Panaji, Nov 6,2k9 (UNI) The first batch of the 29th Indian Scientific Expedition to Antarctica left today to the Maitri base research station in the icy continent to explore the area for benefiting humanity.

Dr P Elango of the Indian Institute of Geomagnetism led the 12-member team of scientists by flight via Mumbai through Cape Town. He will replace the leader of the 28th expedition Dr Pradeep Malhotra.

Informing this to UNI here today, director of the National Centre for Antarctic and Ocean Research (NCAOR) Dr Rasik Ravindra said three other batches of scientists would leave for Antarctica by the end of this year to meet the mission objectives.

The main objective this year was to reach Larsemann Hills in the continent for setting up the third Indian base research station, 3000 KM away from the existing Maitri station.

The new station was likely to be launched by the year 2011-12 if everything goes well. The logistics operations had been completed earlier so that the new batch of scientists could start laying approach roads to the Larsemann Hills before dispatching modules for setting up of the station.

It might be recalled that the existing station Maitri had been in use by the scientists since 1988 after abandoning the first station named after the north Indian river the Dakshin Gangotri following a blizard.

The scientists however completed deep drilling operations in the Antarctica but continued shallow drilling, 100 to 150 Metres deep for collection of ice-cores to study the environment and various other aspects of the atmosphere and the continent datable to 20,000 years back.

Setting of the third station would further facilitate research by the Indian scientific team which had been coordinating as a nodal agency by the NCAOR under the union ministry of earth sciences through an integrated approach coordinating different universities and research bodies across the countries.

''No purpose would be served if the scientists engaged in deep drilling with several other countries already drilling several Kms deep into the ice-core,'' he said.

Interestingly, Indian scientists had identified As many as 25 new species of life in the icy continent collected in the ice cores during analysis made at the Hyderabad-based Centre for Cellular and Molecular Biology as against 125 made by other countries.

The ice-core studies for new life was expected to unravel the mysteries and origins of life of the earth besides exploring the various climates existing over the years millions of years.//EOM//

Third Experiment for Extra-Terrestrial Life beyond Earth in 2010

2009-10-12T23:36:00.001-07:00

Panaji, Oct 11-2k9 (UNI) Bouyed with the first two experiments, Indian
astrophysicists, in collaboration with the space scientists have
decided to conduct a third experiment of sending a balloon with a
payload into atmosphere to collect unpolluted air samples for
proving the existance of life beyond the Planet Earth next year.
Disclosing this to UNI on the sidelines of a public lecture
on ''Searches for micro-life in the erarth's atmosphere'' at Kala
Academy here today, celebrated astrophysicist Dr.Jayant V.Narlikar
said the concerned scientists had now been engaged in a ''brain
storming session'' on the experiment at the Pune-based
Inter-University Centre for Astronomy and Astrophysics(IUCAA).
Unlike in the first two experiments in 2001 and 2005, the
scientists would like to subject the air samples to ''isotopic
composition study'' to find out the anomaly whether the carbon and
nitrogen present in the bacteria collected was not similar to the
ones similar to those on the earth.
''The anomaly could be established by nucldear analysis of the
bacteria to be collected from the atmosphere far above the Earth to
find the existance of extra-terrestrial life beyond the Earth,''
Dr.Narlikar said.
In the first ISRO-Cryosample experiment in 2001, the scientists
had sent a huge balloon from Hyderabad facility to collect air
samples at heights of 41 km above the sea level.
The samples, tested unhder confocal microscppe at two different
foreign laboratories and at the Centre for Cellular and Molecular
Biology at Hyderabad noticed rod and sophere like bacteria besides
fungus.
Their analysis, completed in 2003 found that the new bacteria
could survive even the ultra violet radiation meaning it originated
from the space, but not the earth.he said.
Encouraged by the discovery, the scientists had conducted the
second improved version of the experiment with astrobiology payload
in April 2005 to complete the analysis in 2008.
Surprisingly, the samples collected included 12 bacterial and 6
fuingal coloies. Gene Sequencing of the 9 samples revealed that 98
per cent of them were similar to the species known on the earth
whereas three others were different.
Two of them were named after ISRO and Aryabhatta and the third as
Jankibacger Boylei. It was conclusively proved that the species were
from extra terrestrial source, debunking the suspicion that it could
have been molecules out of volcano eruption which however could not
spew beyond 24 km into the atmosphere.
Dr.Narlikar, who doled out the details of the two experiments in
the public lecture after explaining the ''socmic hierarchy'' that
included the Earth, said the two experiments hitherto had revived
the hope of existance of extra-terrestrial life which needs to be
found out through more experiments for conclusive evidence.
''I hope, we can succeed in having a dialogue with
extra-terrestrial life in the finest form. Life exists in the
universe resembling that on the Earth as per circumstantial evidence
gathered,'' the Padmavibhushan said.
There are as many as 10 to the power of 21 stars(put 21 zeros
after the number 10) in the ''observable universe''. Studies showed
that the space environs contained organis and inorganic
molecules/complunds such as carbon monoxide, carbon dioxide, alcohol
and syanide.
The search for primitive life form in the form of cells, bacteria
and micro-organisms should continue as thdey were responsible for
evolution of life on earth as per the Darvinian therory, he said.
The theory of fifth century BC greek philosopher Amaxagoras saying
the presence of seeds of life(panspermia) travelling across the vast
stellar spaces(spores of life) got further support in 19th century
AD by LOord Kelvin and later by Svente Ahnius(1903).
It was however rejected by Bacque (1924) sayuing micro-organisms
could not survive the ultraviolet radiation in space.The theory
oflife was later revived in 1978 by Fred Hoyle and Chandra
Wikramsinghe.
They revealed that ''comets can be carriers iof micro-organisms in
frozen state releasing them into the earth's atmosphere if their
tails brush them like dust particles by a broomstick after cleansing
the floor''.
''Cometary debris in inter-stellar showers can alsos bring
micro-organisms tothe upper parts of the atmosphere, which might
have planted seeds of life on earth through the sohwers,''
Dr.Narlikar said.
With the stratosphere between 40 and 45 km above the earth not
contaminated, the two baloon experiments were carried out to collect
the sample air particles in 2001 and 2005 with encouraging results.
The samples from the troposphere(upto 18 km above earth) and
ionosphere(beyond stratosphdre) could not be depended upon as they
contain contamination air in the former and low density air with a
few particles in case of the latter, he added.
The air samples were collected using payload containing 16 sterile
stainless tubes that could be opened and closed through a remoter
command from the ground.
Replying to a querry from the audience, Dr.Narlikar said Russians
had conducted a similar experiment using payload attached to a
rocket during 1978-79 without observing biological aspects of the
protocol which was done by the Indian scientists for the first time.
Doing a similar experiment in the Moon environs was of no use
because there was no atmosphere itself but could be tested by
analhsing the surface samples.
He also ruled out hanging of the bacteria from out of space debris
coming back to the earth's atmosphere, interfering with the
experiments as it could be very rare event.
Referring to the phenomenon of the Unidentified Falyign
Objects(UFOs), he asked the people not to be carried away by the
claims reported in media as they were not a reality but optical
illusion of the Venus.
He also dubbed ''astrology as unscientific'' as experiments on
predicting the mentally challenged people on the basis of 400
horoscopes by astrologeres failed to yield results as much as
''predicting the possibility through chance tossing of a coin''.
The scientist had earlier inaugurated an exhibition on astronomy
aimed at popularising the science,particularly among the youth.The
event was organised under the aegis of the Association of Friends of
Astronomy and the Department of Science,Technology and
Envionment,Goa.//EOM//

Toddy drinkers munch endangered turtles meat in literate Kerala

2009-08-28T03:41:00.000-07:00

BY: Y.Bala Murali Krishna
Panaji, Aug 16-2k9(UNI) Scores of soft shelled fresh water turtles, hitherto included in the most endangered list of wildlife species, have been poached and butchered to serve as delicacy for munching by the customers of toddy shops and restaurants in the highly literate state of Kerala in South India.

The traditional belief among the locals that consumption of the turtle meet would cure them joint pains and other diseases, had worsened the situation with poachers hunting these creatures along the course of the Vembanad Lake and Punnamada wetlands

A study conducted by three Kerala-based researchers found that the Indian pond Terrapins and flat-shelled turtles have been poached and killed to meet the growing demand particularly of the toddy shop customers.

“Despite being accorded the highest level of protection in the Indian Wildlife Protection Act, very little law enforcement takes place and the turtles are exploited and traded in this region,” the researchers bemoaned.

They urged the authorities for immediately launching an awareness drive to “sensitize” the local fishermen, turtle hunters and restaurant owners on the need for observing the relevant wildlife laws as also biological and socio-economic impacts of turtle exploitation and trade.

Their findings were published recently in the popular journal of “Tropical Conservation Science” under the title “Protected on paper, hunted in wetlands: exploitation and trade of freshwater turtles
(Melanochelys trijuga coronata and Lissemys punctata punctata) in Punnamada, Kerala, India.

Tropical Conservation Science, a peer-reviewed, open-access academic journal, seeks to provide opportunities for scientists in developing countries to publish their research in their native languages.

The researchers are K. Krishnakumar, Conservation Research Group, St. Albert’s College, Kochi, Rajeev Raghavan, Community Environmental Resource Center, Ashoka Trust for Research in Ecology and Environment, Alappuzha, Kerala, and Benno Periera,
Department of Aquaculture( St. Albert’s College) and Durrell Institute of Conservation and Ecology, University of Kent, Canterbury, UK.

“Soft shell turtles are among the most threatened groups of freshwater animals that are in need of urgent conservation attention, ” the researchers said.

In Kerala, two species of freshwater turtles, the Indian black turtle or Indian pond terrapin, Melanochelys trijuga coronata (Schweigger, 1812) and the Indian Flap-shelled turtle Lissemys punctata punctata (Lacépède, 1788) are exploited from Vembanad lake and associated wetlands in Punnamada to meet the demand from local restaurants and toddy shops.

Eight hundred and forty three turtles belonging to the two species (499 pond terrapins and 344 flap-shelled turtle) were observed during a field survey conducted in 2007 at Punnamada.

“Despite being listed at the highest level in the Indian wildlife protection act, very little law enforcement takes place and turtles are
exploited and traded regularly, the researchers observed.

Collection and trade have also become an important component of the local livelihoods in Punnamada, with the involvement of around five full-time and 25 part-time collectors.

The international trade in wildlife, worth billions of dollars, is known to threaten around one-third of birds and mammals worldwide making it the second-largest direct threat to many species after habitat loss. Much of the wildlife trade is illegal and unsustainable, driven by high profit margins and, in many cases, high prices paid for rare species, the researchers argue.

Turtles are considered to be of particular conservation concern because their life history includes low reproductive output, late maturity, and habitat requirements of wetlands and terrestrial environments.

Many turtle and tortoise species depend on high adult survival to offset high egg and juvenile mortality in the wild. Removing even small fractions of adults from a population can cause declines or delay a population recovery.

Freshwater turtles around the world are threatened by increasing collection for food, perceived medical purposes, and the pet trade, with 159 species, or ca. 60%, of the group being more or less threatened.

In Southeast and East Asia, more than half of all freshwater tortoises and turtles are listed as “critically endangered” or “endangered”. Although tropical Asia supports the world’s richest assemblage
of freshwater turtles and terrapins, it is also the region where exploitation and trade of the group are at their maxima.

Over-exploitation has been observed to be the single most important threat to Asia’s freshwater turtles, with collections largely carried out to satisfy local markets in the Far East and also to support an
extensive international trade for food, or as pets, or as ingredients in traditional Chinese medicine.

The trade nexus is China, the world’s largest consumer of turtles, where the meat and shells are thought to have medicinal value. The growing importance of China as the focal point for trade has resulted in an increased attention to the region in terms of research,and several publications have documented the collection and trade of turtles in the country.

However, compared to China and the Far East, there is very little
information available regarding exploitation and trade of freshwater turtles from other parts of Asia, especially India, the researchers said.

India has one of the most diverse chelonian faunas in the world with the presence of 28 species of tortoises and freshwater turtles. However, 40% of this fauna is threatene, making India one of the top five Asian countries in terms of its importance for turtle conservation.

The most important driver of endangerment for India’s freshwater turtles is the thriving trade that exist in the northeastern and central regions.

In India, nine species of chelonians are known to be harvested on a commercial scale and several others on subsistence levels, leading to localized loss of species diversity and declining turtle populations.

Anecdotal reports point to the extinction of freshwater turtles from the state of West Bengal. Mahanadi river basin in the Eastern Indian state of Orissa is currently the “hub” of freshwater turtle exploitation and trade in the country.

It is estimated that around 200-300 kg of freshwater turtles are transported out of the area on an annual basis. Excepting a few studies from Northeast India , trade in freshwater turtles and tortoises has not been documented from other regions of the country, especially the south.

In Kerala, the southernmost state of India, where large areas are under wetland ecosystems, no study had focused on the collection and trade of freshwater turtles.

The present study was undertaken to assess the exploitation and marketing of freshwater turtles in the Punnamada region of Vembanad Lake—a large wetland ecosystem in Kerala.

The Vembanad-Kol wetland system and its 10 associated drainage basins on the southwest coast of the Indian peninsula are characterized by a continuous chain of lagoons or backwaters—one of the largest estuarine systems in the region. MORE/BM/

The wetland system covers an area of 1,512 sq km. and has been designated as a “Ramsar Site” (Wetlands of international importance) in view of the rich biodiversity and socio-economic profile of local communities.

Punnamada, with a population of 3,562 people comprising 953 households, is a low-lying area connected to several kilometers of extant paddy fields in the southern region of the Vembanad lake.

Of all the freshwater turtles that are consumed, softshells (Family Trionychidae) are considered the best, due to their low bone-to-body ratio and larger proportions of cartilage and gelatinous skin.

This demand has made softshells the most important component of the freshwater turtle trade in Asia. A total of 950,251 individuals of 157 turtle species were recorded during a 35-month survey of the turtle trade in Hong Kong and southern China, revealing the magnitude of collection and trade in the region.

The quantification of 843 individuals in 12 months, observed in the present study, is higher when compared to 245 freshwater turtles in eight months recorded from Nanmao, Hainan Province, China, during a survey in 2003.

The collection techniques for freshwater turtles in Punnamada are similar to those practiced elsewhere in India as well as the rest of Asia. In the Malaysian island of Borneo, local fishermen are known to
routinely set hooks and lines to catch turtles, whereas fish traps are known to be more common in Laos.

In Mahanadi basin on the east coast of India, freshwater turtles are caught with a variety of gear including floating hooks, harpoons, and baits.
All turtles observed in the trade at Punnamada were larger than 15cm TCL. This preference for medium- and larger-sized turtles is different from that seen in other parts of Asia.

Turtles collected from parts of Southeast Asia are generally destined for two important markets—the growing pet trade based in Singapore and the food market based all over Southeast and Far East Asia.

Most turtle dishes served in Southeast and East Asia use whole animals as compared to South India and Punnamada where an individual turtle is cut up and used to serve many.

Since most dishes served in Southeast and Far East Asia use whole turtles, they require small or medium-sized individuals that can fit on such plates. The ever-growing pet trade in the region also requires smaller individuals for keeping in homes.

Young turtles that weigh less than 200g fetch a high price in the market of Assam, India. The price of turtle meat/Kg in Assam is around US $7.5 which is higher than the market prices that we observed in Punnamada (4-6 US$/Kg, given the fact that 200g to 400g of meat is obtained from an individual turtle).

In many parts of India (e.g., in Assam), turtle blood is believed to be a cure for piles and fistulas. Contrary to this, consumers in Kerala dislike turtle blood and are never known to drink it. Large-scale cultural differences exist between people residing in different parts of India and are largely responsible for this difference.

However, the perceived medicinal property of turtle meat as a remedy for gout, rectal disorders, and arthritis is known among people of all regions in the country , including Punnamada as revealed in
the present study.

The study had recommended undertaking of extensive micro-geographic surveys throughout Kerala and particularly in Vembanad Lake to assess the demography and current conservation status of M. trijuga and L. punctata species, and for generating baseline data on their life history and ecology.

They further favoured proper protection of turtle habitats in the Vembanad wetland, especially nesting sites of the two species
and a community-based monitoring and conservation program involving local fishermen and turtle collectors after completion of the baseline studies.

The study also recommended continuous monitoring of the local turtle trade in conjunction with toddy shop owners, and public awareness campaigns directed at fishers, turtle collectors, and toddy
shop owners to sensitize them to the need for conserving turtles.

Development of a cluster of turtle breeding and farming units was also suggested to diminish the pressure on wild stocks, providing
The local communities with a livelihood opportunity, besides programs to organize turtle collectors in the region to take up breeding and culture of local species.UNI/BM/

We Can Easily Sail to Arctic by the year 2020!

2009-04-16T07:12:00.000-07:00

BY: Y.Bala Murali Krishna

Panaji, Apr 16-2k9(UNI) Can any one dream of sailing easily to the North Pole, wading through the icebergs amid bone biting sub-zero temperature?

“ Yes, by the year 2020,” says Dr.Simon Boxall, a specialist on climate change attached with the University of Southampton, National Oceanography Centre (UK).

This is possible owing to decrease in ice cover following drastic climate change that is melting the ice in the Arctic continent, he says.

The scientist was delivering a public lecture in collaboration with British Council on "Climate Change from the Arctic to India - Myths, facts and ways forward" at the National Institute of Oceanography (NIO) here today.

The significant impact of climate change would be noticed in India where a majority of the population live along the coast or in flood prone regions, he opines.

New political moves in the US, the world's greatest contributor to climate change, look set to address some of the issues related.

“However it is in India and China where the biggest advances must be made in the next twenty years if climate change is not to effect a global change,” Dr.Boxall says.

Technology in India needs to lead the way in defying convention for power supply and technology in homes, transport and industry.

It has the most to gain, both in terms of a sustainable environment and in profit from novel science and technology, he said.

Dr. Simon Boxall began his career at the University of Liverpool and has worked with the UNESCO, The European Union Research Centre, The World Bank and European Space Agency over the years.

His current research interest covers a spectrum of topics from oil spills to coastal dynamics but he had spent most of his time on studying climate change and the ocean. UNI/BM/

Experiment on Southern Ocean to Reduce Global Warming Fails

2009-04-16T07:01:00.000-07:00

BY: Y.Bala Murali Krishna

Panaji, Apr 13-2k9(UNI) An ambitious Indo-German experiment, just concluded on far-off Southern Ocean, to sequester atmospheric carbon dioxide by dumping iron power, has dampened the hopes of the scientists.

The experiment, christened “LOHAFEX”, launched amid severe criticism from the environmental groups, however yielded some “surprising insights on plankton ecology” which are under study.

Loha in Hindi stands for iron and Fex for fertilization experiment. The scientists hoped that dumping of iron power in the oceans may result in oceans absorbing atmospheric carbon dioxide thus reducing global warming in a big way.

Emboldened by the initial success of similar small scale experiments on the ocean, the scientists of the National Institute of Oceanography (NIO) here under the umbrella of the Council for Scientific and Industrial Research and Germany’s Alfred Wegener Institute for Polar and Marine Research (AWI) had undertaken the experiment through the research vessel Polarstern for about 75 days.

They, along with scientists from five other nations who joined the study, returned home after the ardous expedition, to analyse the data they obtained from the “Roaring Forties” of the Southern Ocean where they had fertilized a patch of 300 square kilometers area with four tonnes of dissolved iron powder.

They studied its “effect on the plankton and on ocean chemistry
including concentrations of carbon dioxide and other radioactively important gases continuously for 39 days.

“The experiment has yielded new insights on how ocean ecosystems function but has dampened hopes on the potential of the Southern Ocean to sequester significant amounts of carbon dioxide from the atmosphere and thus help mitigate global warming,” The NIO source said.

As expected, iron addition stimulated growth of the planktonic algae (phytoplankton) which doubled their biomass within the first two weeks by absorbing carbon dioxide (CO2) from the water. The initial uptake depressed partial pressure of CO2 by up to 15 micro-atmosphere, says Co-Chief Scientist Dr. Wajih Naqvi of NIO who was on the voyage although.

However, contrary to expectation, further growth of the phytoplankton bloom was stopped by increasing grazing pressure of abundant,
small crustacean zooplankton (copepods), after which the planktonic ecosystem entered a recycling mode.

As a result, further CO2 uptake declined and only a modest amount of carbon sank out of the surface layer by the end of the experiment. Hence, the transfer of CO2 from the atmosphere to the ocean to compensate the deficit caused by the LOHAFEX bloom was smaller than in most previous experiments, he said.

The larger blooms stimulated by earlier experiments were due to a group of algae known as diatoms which were protected against grazers by shells made of glass (silica) and were known to sink to great depths after blooming.

Diatoms could not grow in the LOHAFEX experiment because all the silicic acid (the raw material of diatom shells) had already been extracted by previous, natural blooms. These were presumably fertilized by natural sources of iron such as melting icebergs and dust blown off Patagonia.

Hence a major finding was that other algal groups, although stimulated by iron fertilization, were unable to make blooms equivalent to those of diatoms. Since the silicic acid content of surface waters in the sub-Antarctic zone (the region located between the Polar Front and the Subtropical Convergence that accounts for half of the total area of the Southern Ocean) is low, iron fertilization in this vast region is unlikely to result in removal of significant amounts of CO2 from the atmosphere.

“To our surprise, the iron-fertilized patch attracted large numbers of zooplankton predators belonging to the crustacean group known as amphipods” explains Professor Dr Victor Smetacek, co-chief scientist from the AWI.

These shrimp like crustaceans are between two and three centimeters long and feed indiscriminately on other zooplankton including copepods but also organisms much larger than themselves such as salps and chaetognaths.

The dominant species (Themisto gaudichaudii) is the main food of squid and fin whales in the south-western Atlantic. This finding is of particular interest because the amphipods’ biomass in the patch approached that of the better-known krill in productive waters further to the south.

Indeed, before decimation of the populations of great whales by the 1960s, there were many more fin whales feeding on amphipods in the northern zone of the Southern Ocean, than there were blue whales feeding on krill in the southern zone.

However, much less is known about the biology of Themisto than of krill, although it provides the food base of the extensive squid fishery in the south-western Atlantic.

LOHAFEX thus provided unexpected insights into the ecology of this neglected key species. A second fertilization of the patch after 3 weeks had no further effect on the phytoplankton indicating that the ecosystem was already saturated with iron.

Algal species which regularly make blooms in coastal regions including the Antarctic, were most heavily grazed and replaced by tiny algal cells, only slightly larger than bacteria, that are too small to be gathered by copepods.Up to 20 million cells per litre of these minute algae were recorded.

Interestingly, the plankton community in the unfertilized water surrounding the patch developed in the same way and had the same species diversity but was operating at a lower level of biomass.

“The bacterial community both inside and outside the patch was very
similar and their cell numbers remained unusually low throughout”, said Dr. Bernhard Fuchs of the Max Planck Institute for Marine Microbiology (Bremen).

This implies that most of the nutrient recycling (including iron) was carried out by the zooplankton. This is a articularly surprising finding because the microbial food web based on bacteria is believed to be the base of all recycling planktonic ecosystems.

Concentrations of gases other than CO2 produced by the plankton, some of which are potent greenhouse gases such as nitrous oxide and methane and others, such as halogenated hydrocarbons which contribute to stratospheric ozone depletion, either did not change or increased negligibly in the bloom.

By the end of the experiment, chlorophyll concentrations were in decline and the patch will by now have merged with its surroundings leaving behind no trace other than swarms of well-fed amphipods that will probably disperse to feed in less productive waters.

These preliminary findings will be supported by additional measurements to be accomplished in the home labs on the many frozen and preserved samples collected during the cruise. The data will be refined and interrelationships between the organisms quantified in the coming months.

These will be intensely discussed and prepared for joint publication in scientific journals at workshops to be held in Goa by the end of the year. Participants of LOHAFEX are,however, extremely satisfied with the results.

“It was a strenuous cruise, full of anxiety and hope as we chased our patch around the collapsing eddy. On one occasion we expected it to be sucked out and dispersed by the strong currents surrounding it, but the
patch was stayed as if by a miraculous hand at the exit and hovered there for two weeks until we had to leave”, said Victor Smetacek.

Strong winds were almost the rule, and the vessel had to leave the area to avoid big storms twice, although shorter storms with wind speeds of over 120 km per hour were weathered on site. Nevertheless, despite the hard work under difficult circumstances, LOHAFEX has been an exciting experience laced with the spirit of adventure and haunted by uncertainty quite unlike other scientific cruises.

“Despite coming from seven different countries and having diverse scientific backgrounds, scientists on LOHAFEX worked for a common cause and lived like a big family.

The experiment thus provides an excellent example of international collaboration in interdisciplinary ocean sciences”, said Wajih Naqvi.”

“The officers and crew of the Polarstern did a fantastic job in providing
technical support under testing conditions without which the expedition could not have achieved its objectives”, he added.//EOM//

Marine Bacteria May Be Future Source of Batteries

2009-04-07T09:18:00.000-07:00

BY: Y.Bala Murali Krishna
Panaji,April-7-2k9 (UNI) Marine bacteria may be the future source of portable and rechargeable batteries.

They could be used in mobile phones, calculators,microsensors or even body implants like the pace makers for heart patients.

Termed as Microbial Fuel Cells, the Bacterial Batteries,if introduced in even the water treatment plants, could produce electricity by consuming the organic waste.

"This provides us a very clean, efficient and emission free source of generating electricity," if the experiment at the biotechnology department of a local college is to be believed.

The department's student Ms.Natalie D'Silva of the Dhempe College of Arts and Science, run under the Dempo Charities Trust, at Miramar,had today proved she could produce a voltage of 0.47 volts through a circuit of two poles kept in a test tube using the marine bacteria as the source and different organic waste as the media.

These values are much higher than those reported in scientific journals so far. The electricity thus generated could be stored in rechargeable cells or capacitors and utilised whenever needed, thus providing a potential energe source.

Yet to be identified, the bacteria was isolated from three types of marine sponges found in the sea waters of Betul in South Goa. A prototype experiment was carried out in Austraila.

Experiments are at the initial stage and it is to be found whether the voltage and the current output could be enhanced using different media.The project baged a special prize at the state level S&T exhibition recently.

"But the Goan experiment has potential to emerge as a source for cheaper and portable rechargeable source of energy with many applications in modern life," claims Ms.Natalie and her guide Mrs.Arina Frank, the department lecturer.

The objective of the project is to develop MFCs or bacterial cells in which chenical energy is converted into electric energy by bacteria, with non-renewable sources depleting besides causing environmental damage.

Most of us hear of the phenomena of "bioluminiscence" in marine oranisms that illuminate the objects around in the oceans. On similar lines, certain bacteria have the potential to generate
electricity as they work like fuel cells.

This happens when the microbes feed on biomass for respiration releasing electrons and protons.The electrons are transferred to the cathode compartment through an external electric circuit and the protons to the anode through the membrane.

"The biotechnology deparment of the college encourages students to take up research projects to enhance their knowledge, skills and confidcence tobecome future scientists as envisoned by former president APJ Abdul Kalam," claims the college principal Dr.Deshpande.

Some of the projects had been funded by the Department of Atomic Energy and the Department of Biotechnology,tand the subjects ranged from enzymology, solid wasgte management, plant and animal cell culture and immunology, he added. //EOM//

Indo-German scientists team to sprinkle iron in Antarctic

2009-04-04T08:35:00.000-07:00

By Y. Bala Murali Krishna

Panaji, Jan 12-2K9 (UNI) Can sprinkling of dissolved iron in the oceans help absorb the deadly green house gas of carbon dioxide from the atmosphere?
Possibly yes, say scientists.
Amid protests by global environmental groups, an India-Germany scientific research team has now set sail for the Southern Ocean in a bid to test the efficacy of sprinkling of iron in the Antarctic in absorbing atmospheric carbon to reduce green house gas effect at low cost.

Code-named "LOHAFEX", the joint experiment tests the effects of iron fertilisation on ecology and carbon uptake potential of the Southern Ocean. A team of 48 scientists, 30 of them from India, had already left for Cape Town in South Africa by the German research vessel "Polarstern" on January 7 without any publicity blitz.

LOHAFEX is an international collaborative research project jointly conducted by Germany's Alfred Wegener Institute for Polar and Marine Research (AWI) and the Goa-based National
Institute of Oceanography (NIO), together with scientists from nine other institutions in India, Europe and Chile.

NIO sources told UNI here today that Victor Smetacek(AWI) and Dr. Wajih Naqvi (NIO) are Co-Chief Scientists of the project for which heads of the parent organisations-Helmholtz

Association, Germany and the Council of Scientific and Industrial Research (CSIR), India had signed a Memorandum of Understanding in the presence of the German Chancellor
Angela Merkel and Prime Minister Manmohan Singh in New Delhi on October 30, 2007.

LOHA in Hindi stands for Iron and FEX stands for fertilisation experiment that is to be conducted in the Southwest Atlantic sector of the southern ocean. It takes at least 20 days to reach the area where after the selection of a suitable site, the scientists will dump six tonnes of

dissolved iron in a patch of 300 sq. km. The cruise will end at Punta Arenas, Chile on March 17.
The iron fertilisation experiment, the scientists expect, will "lead to rapid growth of the minute, unicellular algae(phytoplankton) that not only provide the food sustaining all oceanic life but also play a vital role in regulating concentrations of the greenhouse gas CO2 in the atmosphere,"sources said.

Scientists claim five earlier experiments carried out in the southern ocean, including two conducted from RV Polarstern, induced phytoplankton blooms of similar size and composition to natural blooms fertilised by iron in settling dust and from melting ice bergs.

However, in contrast to the land-remote regions previously fertilised, LOHAFEX will be located in a more productive region of the southern ocean inhabited by coastal species ofphytoplankton. These grow faster and are more palatable to the zooplankton, including the shrimp-like krill, than their spiny open-ocean counterparts.

Krill is the main food of Antarctic penguins, seals and whales but their stocks have declined by over 80 per cent during the past decades, so their response to the iron-fertilized bloom (if they are present in the experimental area) will indicate whether the alarming decline is due to declining productivity of the region, for which there is evidence.

Because it will last much longer, the LOHAFEX patch will also be twice the size of previous experiments to counteract the effects of dilution due to spreading over the 45 days ofthe experiment. Previous experiments showed that effects on the environment were benign and short-lived, scientists stated.

Dismissing media reports against the experiment and protests by environmentalists, the scientists said the LOHAFEX experiment does not violate any existing international law.

"It is being erroneously reported that there exists a moratorium on Ocean Iron Fertilisation (OIF) experiments placed by the UN Convention on Biological Diversity (CBD). The CBD recommendation was aimed at preventing large-scale commercial OIF activities, making an exception for scientific experiments," the scientists maintained.

That such experiments were to be restricted to coastal waters was perhaps an aberration, which has since been amended. The resolution adopted by the parties to the London Conventionand Protocol of the International Maritime Organization(IMO)during a meeting held at London in October 2008 does, in fact, call for further research on OIF, the scientists clarified.

"It clearly states that legitimate scientific experiments should go on, without restricting such experiments to coastal waters. The IMO resolution, although not legally binding, prescribes that proposals for such experiments be evaluated on a case-to-case basis taking into account possible environmental impact," the scientists said.

The LOHAFEX experiment is a small-scale experiment that will not cause any damage to the environment. As an example, the level to which the surface-water iron concentrations will be enhanced during this experiment is an order of magnitude lower than natural iron levels in coastal marine environments, they claimed.

"In fact, this concentration is so low that most analytical laboratories in the world cannot measure it. In addition, the scale of the experiment will be of the same order as that ofprevious OIF experiments," the scientists noted.

They alleged that the groups opposing LOHAFEX were not only unaware of the legal status, but were also not knowledgeable enough about marine environments. Thus, they were indulging indisruptive activities merely to draw media attention to themselves, the scientists added.

Environmental campaigners said LOHAFEX should not have been granted permission under international rules and that the 300 sq. km. experiment is neither small-scale, nor confined to coastal waters.
"We are taken aback by this flagrant disregard of international law," Mariam Mayet, director of the African Centre for Biosafety in Johannesburg said.
"Of all countries, Germany, which brokered the moratorium, has jumped the gun on the ocean fertilisation issue again," she added. //EOM//

Pollution: CB has Ambitious Monitoring Plans in Goa

2009-04-04T08:29:00.000-07:00

By Y Bala Murali Krishna

Panaji, Jan 11-2k9 (UNI) The Goa State Pollution Control Board (GSPCB) has plans to install automatic display boards indicating the levels of pollutants in ambient air at different places. It has also planned to prepare ''status reports'' on various waste management aspects, including solid waste, sewage, biomedical, plastic, e-waste, batteries and hazardous industrial wastes, allwith funds from the Central Pollution Control Board (CPCB).

Talking to UNI here today, GSPCB chairman L U Joshi said the board was also trying to develop a software package for total computerisation of its activities like consent management, which fetches considerable revenue to the board.

The board with Rs 2.71 crore fixed deposits base and earning of Rs 1.15 crore as consent fee from different industries in 2003 has now achieved a whooping Rs 21 crore FD base and an annual consent fee of Rs 2.5 crores under his stewardship.

He also claimed to have provided sixth pay commission recommended wages to all its employees alongwith a highly computerised work environment at its Patto office headquarters in the heart of the capital city.

Meanwhile, the board had prepared the State Environment Atlas, the Zoning Atlas and Sitting Guidelines for Industries under a project funded by the CPCB for Spatial Planning.

''The documents were forwarded to the state government for consideration and implementation after getting approval from the CPCB. The recommendations made in the reports were considererd in the Draft Regional Plan 2021 for Goa,'' he said.

The board was also trying to dfisplay information of all industries in the state on its website. It had also sought the assistance of the Union Ministry of Environment and Forests for procuring a mass spectrometre, Liquid Scintillation Counter and HPLC equippment for measuring various types of pollutants in Goa.

At present, it was engaged in collecting and analysing water samples from 29 locations from rivers and other water bodies in Goa for passing on to the CPCB apart from analysing ambient air quality at the most polluting Mormugao Port, besides Vasco-da-Gama and Panaji.
Meanwhile, efforts were on to acquire a common site by the state government for disposal of hazardous waste and bio-medical waste at Darbandora.

Presently, the hazzardous waste was beiong treated and disposed at Maharashtra's Taloja facility. Goa generates about 10,000 tonnes of hazardous waste. Interestingly, Bombay High Court at Goa, hearing a case suo moto on waste management as a public issue recently directed the GSPCB to present status reports on disposal of various wastes including municipal,biomedical and hazardous.

The board headquarters is now fully equipped with sophisticated instuments to analyse toxic and trace metals, ambient air and water quality in its analytical laboratory set up in collaboration with the CPCB and MOEF.

It was also in the process of introducing more mobile laboratoties to determine pollutants in the state. //EOM//

Rain Water Harvesting to be Compulsory in Goa

2009-04-04T08:18:00.000-07:00

BY: Y.Bala Murali Krishna
Panaji,Aug 3-2k8(UNI) Goa,perched on the wastren ghats receiving abundant rainfal every year but often experiencing shortage of water,is keen to make rainwater harvesting compulsory soon.

Visited by tourists numbering more than its own 14 lakh population, this international tourist destination feels choaked at most of the favourite tourist hotspots where ground water is contaminated, causing concern to the authorities.

To circumvent this situation, the government is also seriously examining a proposal to offer incentives to individual households, residential and commercial complexes besides hotels and industries to encourage them undertake scientific techniques of rainwater harvesting.

Similar schemes have been in vogue in neighbouring states like Kerala and water starved Tamilnadu and Andhra Pradesh where rain water harvesting,along with cloud seeding techniques gathered momentum to save precious life saving liquid resource.

The proposal of the Goa water resources department is yet to get the cabinet nod. It is likely to come up for discussion and approval very soon, informed sources told UNI.

Goa,spread over an area of only 3,702 square kms, receives an average 300 CMs rainfall every year during June to September and most of it drains into the sea,bemoan scientists.

Hydrologists estimate basinwise average rainwater runoff at a total of 8570 million cubic metres every year and maintain that this entire water resource should not be mistaken as available for
harnessing.

There are nine river basins in Goa with Zuari having the highest length of 145 km. Many of these rivers are tidal prone upto a distance of 20 to 40 kms and the utilisable part of the yield should be identified basinwise.

Macro level surveys indicate that the ground water is availalble to the tune of 267 million cubic metres(MCM) and its utilisation to the tune of 27 per cent which is considered safe, though authorities noticed some stressed areas in the coast and industrial belts.

In the post monsoon period, the effluent river flows start dwindling and very few rivers or rivulets remain perinnial, obviating the developmental water resources scenario calling for a blend of storage and run of the river schemes for optimal surface water utilisation.

As against an estimated 1465 MCM water available, Goa has a storate capacity of only 690 MCM. Ever increasing demand for more wager and global warming threat calls for increased storage capacity which could best be met by rainwater harvesting and water recycling
techniques, authorities argue.

They maintain that even if a small percentage of rainwager falling on the rooftop is saved, it will go a long way in reducing the load on drinking water supply which is on rapid rise particularly in
urban areas.

It is estimated that the consumptive use of water is only about 15 o 20 per cent against 135 litres per capita per day water required for different needs including bathing,cooking,washing, flushing and gardening.Use of rainwater can suffice many of the needs of non-consumptive uses.

The authorities had proposed to make rainwater harvesting compulsory on residential complexes including apartments on a plot of area of 2000 square metres(SM) and above, commercial complexes on plot area of 100 SM and above and industrial units with 10,00 SM and above.

They had also favoured subsidies by way of incdentives on reimbursable basis 50 per cent of cost of Rs.50,000 whichever is less for individual households and 50 per cent of the cost or Rs.2.5 lakhs whichever is less for residential complexes/apartments/commercial complexes.

In case of industries, they proposed to offer 50 per cent of the cost or Rs.5 kakhs which ever is less as incentive for adopting approved rainwater harvesting mechanisms.

In addition, the government proposes to offer 10 per cent rebvate in license fee chargeable to the beneficiaries.

It also plans to institute an award annually carrying citastion and cash prize for ghe best rainwater harvesting practices. The authorities had also come out with a mechanism for
implementation of the incentive reimbursement schemes by appointing canal officers as supervisors.

Once approved, the authorities had to bring about suitable amendments to related laws and regulations for implementation of the scheme besides making a budgetary provision for the incentives.

"All this will go a long way in not only reducing the load on treated piped water supply,but creating an awareness and saving inwater utiloisation in the long run," the authorities opined.

Mimic nature to develop anti-corrosive nano-materials

2009-04-04T08:06:00.000-07:00

BY: Y.Bala Murali Krishna

Panaji, Mar 1-2k9 (UNI) Mimic the mother Nature that gives clues to develop sticky and non-sticky nano-materials with vital strategic applications like mitigating corrosion claiming Rs 50,000 crore annual loss to the Indian industry, says a nano-technology expert.

'Nature has plenty of examples like the shark having anti-sticky skin, the gecko (lizard) and the frog with sticky foot/pods. Even the Lotus leaf on the surface of which water does not stick, provides us clues to develop materials with stain resistant, self-cleansing surface texture properties,' avers Prof Asutosh Sharma, department of Chemical Engineering, IIT-Kanpur.

The research could be enhanced using the nano-technology tools through the novel approach to develop anti-stick and anti-skid coatings/paints for potential marine applications to save precious foreign exchange, Prof Sharma told UNI.

He was here recently in connection with the just concluded four-day International symposium on 'Surface Protective Coatings and Paint Exhibition' organised by the Indian Chapter of the Society for Surface Protective Coatings.

Prof Asutosh, also a member of the National Nano Science and Technology Mission, had urged the researchers to take the benefits of the Nano Mission for developing micro/nano-coatings to benefit the industry.

He called for interaction between the academia and the industry for enhancing research on developing anti-corrosion nano-materials using the Nano Mission which offers Rs 50 lakhs soft loans for the researchers.

One can use electric field methods to develop nano-surfaces and textures in fabricating the materials with critical applications. ''Think ahead of the world. No reverse engineering in this research,' he said.

The anti-corrosion market is worth Rs 15,000 crore even as the expenditure on the account was on rise every year with applications on the hydrocarbon sector, particularly offshore structures, power, aerospace and infrastructure sectors. India had been importing anti-corrosion material to the tune of 25 million USD to mitigate the menace.

The Centre has initiated the Nano Mission with a corpus of Rs 1,000 crores for five years with the Department of Science and Technology being the nodal agency for implementing its projects.

Capacity-building in this upcoming area of research will be of utmost importance for the Nano Mission so that India emerges as a global knowledge-hub in this field also.

For this, research on fundamental aspects of nanoscience and training of large number of manpower will receive prime attention. Equally importantly, the Nano Mission will strive for development of products and processes for national development, especially in areas of national relevance like safe drinking water, materials development, sensors development, drug delivery and the like.

The mission will forge linkages between educational and research institutions and industry to promote Public Private Partnerships. The Nano Mission was so structured that it could achieve synergy between the national research efforts of various agencies in Nano Science and Technology and launch new programmes in a concerted fashion. International collaborative research efforts will also be
made wherever required.

The Nano Mission is the result of considerable promotional efforts already put in by the Government of India to promote nanotechnology research. Over 100 research projects have been funded so far. Several centres of excellence on nanoscience and nanotechnology have also been established.

A number of post-doctoral fellowships have been awarded and national and international conferences organized. The Government has spent approximately Rs 200 crore over the past five years to promote R&D in this area. These scientists, facilities and centres will form part of the network of the Nano Mission.//EOM//

Ocean Drilling to Study Age of Himalayas

2009-04-04T07:56:00.000-07:00

BY: Dr.Y.Bala Murali Krishna
Panaji, Mar 2-2k9(UNI) An Indo-British joint scientific study has established that mighty Himalayas that have a bearing on Indian economy through onset of monsoons, started growing 15.4 to 13.9 millions years ago, but not 8 million years as is popularly believed.

To validate the finding further, Scientists of the prestigious National Institute of Oceanography (NIO) here may join the UK team of researchers in deep-sea drilling of the Central Indian Ocean to unlock the secrets of the birth and growth of Himalayas and the strengthening of the India-Asian monsoons.

Disclosing this to UNI here today, a member of the joint study team Dr.K.S.Krishna of the NIO said the deep sea drilling programme, to begin in February 2011 and completed within two months, will be launched under the Integrated Ocean Drilling Programme (IODP) based in the USA and Japan under a consortium for which India has become an associate member recently.

The consortium had cleared the proposal submitted by noted marine geologist Prof. Petre Clift of the University of Aberdeen, UK with the multi-national scientific research focusing on “Mission Monsoon: Climate-Tectonic Interaction in Cenozoic Asia”.

The findings of the Indo-UK study were published in the latest issue of the Geological Society of America journal Geology, on the tectonics-related deformation of the lithosphere below the central Indian Ocean.

India’s Council of Scientific and Industrial Research (CSIR), and the United Kingdom’s Royal Society and Natural Environment research Council (NERC) funded the joint research project, Dr.Krishna said.

The study found that the Earth’s strong outer shell – the ‘lithosphere’ – within the central Indian Ocean began to deform and fracture 15.4–13.9 million years ago, much earlier than previously thought, impacting our understanding of the birth of the Himalayas and the strengthening of the Indian-Asian monsoon.

Other members of the Indo-UK study group, apart from Dr.Krishna, were his British colleagues Prof. Jon Bull of the University of Southampton, and Prof. Roger Scrutton of Edinburgh University.

They analysed seismic profiles of 293 faults (vertical cracks in the ocean floor) in the accumulated sediments of the Bengal Fan. This is the world’s largest submarine fan, a delta-shaped accumulation of land-derived sediments covering the floor of the Bay of Bengal.

They demonstrate that deformation of the lithosphere within the central Indian Ocean started around 15.4–13.9 million years ago, much earlier than most previous estimates.

This implies considerable Himalayan uplift before 8.0 million years ago, which is when many geologists believe that the strong seasonal winds of the India-Asia monsoon first started.

“However,” says Dr. Krishna, “the realisation that the onset of lithospheric deformation within the central Indian Ocean occurred much earlier fits in well with more recent evidence that the strengthening of the monsoon was linked to the early geological uplift of the Himalayas and Tibetan plateau up to 15-20 million years ago.”

The proposed intensive deep-sea drilling within the Bengal Fan would provide better age estimates for the onset of deformation of the lithosphere in the central Indian Ocean and concretise the recent findings.

There are more weighty geological questions related to the geodynamics of the Indian Plate yet to be understood. Principal among them being the issue of how exactly did the ocean floor buckle and crack in space and time, and what will be the future course of this compress ional activity in the central Indian Ocean.

The scientists would like to gather new evidences for understanding of why and how the central Indian Ocean region has now become site where mountains are rising up from the ocean floor and cracks are propagating within the crust.

They would also like to find whether the present process could be a pre-cursor to the formation of a subduction zone in the central Indian Ocean.

India and Asia collided around 50 million years ago as a result of plate tectonics – the large-scale movements of the lithosphere, which continue to this day.

“Compression of the lithosphere has caused large-scale buckling and cracking. The ocean floor has been systematically transformed into folds 100-300 kilometres long and 2,000-3,000 metres high, and there are also regularly spaced faults or cracks that are evident from seismic surveys and ocean drilling, ” says Dr.Krishna.
The onset of this deformation marks the start of major geological uplift of the Himalayas and the Tibetan Plateau, some 4,000 km further to the north, due to stresses within the wider India-Asia area.

Some earlier studies indicated that it began around 8.0–7.5 million years ago, while others have indicated that it started before 8.0 million years ago, and perhaps much earlier. UNI/BM/

Seahorses bred in Captivity at NIO-Goa

2008-09-13T07:26:00.000-07:00

Dr.Y.Bala Murali Krishna
Panaji,Sept 1-2k8(UNI) The scientists of the premier National Instituteof Oceanography(NIO) here have succeded in breeding the Indianseahorse species under captivity for the first time in the country.

The team of researchers led by R.A.Sreepada are confident ofstandardizing the hatchery and mass culture technology that couldhelp conserve and reproduce the species(Hippocampus Kuda), popularlyknown as yellow or spotted seahorse.
The demand for the seahorse species has been rising particularly inthe use of traditional medicine as "aphrodisics and rejuvenators",and as show pieces in the marine aquaria.
The technology, if perfected, would go a long way in supplementingthe revenue of the fisherfolk and self-help groups depending on thetrade, scientists said.
Uneer the project funded by the Department of Biotechnology,government of India, the NIO biologists collected the seahorsespecies from the wild, grew them to maturity,and allowed them tomate and spawn under laboratory conditions through manipulation offeed and environmental conditions.
Their joy knew no bounds on August 29 last when two male seahorsesdelivered 320 new born juveniles which were being taken care in theaquaculture laboratory, known as fraternity home.
Interestingly, the seahorses comprise of a remarkable andfascinating group of marine fish with unusual body shape andbiology, with the males incubating the fertilised eggs in a broodpouch they carry.
Next 15 days are very criticalfor their survival since they shiftfrom pelagic to the settlement phase, the scientists said.
It might be recalled that NIO is one of the renowned ocean researchlaboratories in the world under the umbrella of the Council forScientific and Industrial Research(CSIR).
Horseshoe Crab's Gene Secrets under Scanner:

Significantly, the NIO scientists had also been credited withartificially breeding yet another marine species of horseshoe crabwhich had been facing extinction following indiscriminate drawal ofits blue blood by the pharmaceutical industry.
Known as the "living fossil", the horseshoe crab's blood serum hadbeen used to detect instantly the impurities of even the minutestlevel including the viruses and bacteria in the blood andpharmaceutical storehouses and even spacecrafts.
The scientists had also succeeded in cloning the seahorse in thelaboratory condition and had been trying to perfect the technologyin shortening the process.
The marine creature, which did not undergo an iota of change in itsbody structure for millions of years, was expected to yield clues toits youtufulness and longivity,with appalling applications on human beings.
The scientisrs, through a collaborative research project, were alsotrying to unravel the secrets of regeneration of its gill within sixmonths of its removal from the body by trying to identify the generesponsible for the factor.
If succeeded, the NIO will have the credit of developing atechnology for natural regeneration of affected/mutated human organsinstead of depending on the artificial cloning technology usingfrontier genetic engineering.//EOM//

Himalayas Contributing to Global Cooling,Absorbing Carbon Dioxide

Himalayan basin rivers fast weathering, depleting carbon dioxide:scientist

BY: Y.Bala Murali krishna

Panaji,Sept 26(UNI) Faster chemical weathering of Himalayan rockshave been contributing to global cooling in the region, with itsriver basins rapidly absorbing emissions of the noxious green housegas of carbon dioxide,says a study.

"That earth has been cooling since the last 55 millions of years iswell estalished by scientists. But the contribution of the young andgrowing mountains of Himalayas to the cooling is much more than theglobal average," claims nuclear oceanography expert Prof.S.Krishnaswami.

He was part of the group that had been studying various potentialgeochenical aspects of Indian rivers for the last 15 years under theaegis of the prestigious Physical Research Laboratories, Ahmedabad,one of the 38 laboratories under the Council of Scientific andIndustrial Research(CSIR) umbrella.

Recepient of top science awards including fellowship of the AmericanGeophysical Union and now senior scientist of the Indian NationalScience Academy(INSA),Prof.Krishnaswami was in the capital here todeliver the CSIR foundation Day lecture on "Erosion in River Basins of India: Causes and Consequences" at the National Institute of Oceanography(NIO).

Interacting with this UNI orrespondent on its sidelines, he said the group was yet to undertake the study of the South Indian riverbasins even as it had finished the research on Ganga-Brahmaputraunder the Himalayan region besides the Indus and Krishna rivers.

The rapid chemical breakdown of the rocks in the Himalayan regionhas been contributing to the equally rapid control of carbon dioxideemissions into the atmosphere,, thus resulting in lowering of thetemperature,he said.

The extent of the decrease in temperature and the quantum of thecarbon dioxide drawn-down was yet to be studied on other river basins.

Ocean, he said, occupies 95.96 per cent of the earth followed by2.97 per cent by ice caps and glaciers, 1.05 per cent by groundwater, 0.009 per cent buy lakes and 0.0001 per cent by the rivers water.

In this connection, he had quoted a saying from Srimad Bhagwatam which reads ,"O King!,the rivers are the veins of the gigantic body,the trees are the hairs of His body, and the omnipotent air is His breath. The passing ages are His movements and His activities are the three modes of material nature."UNI/BM/

Indian Scientists Set Foot on Arctic First Time

2007-08-05T07:14:00.000-07:00

BY: Dr. Y Bala Murali Krishna
Panaji, Aug 3-2k7 (UNI) For the first time, India is setting its foot on the Arctic, the icy continent in the extreme north of the globe, inits quest for unlocking the secrets of life and the environment around.

S&T Minister Kapil Sibal flagged off the expedition in New Delhi on Saturday. A five-member team of inter-disciplinary scientists, led by the director of the prestigious National Centre for Antarctic and OceanScience (NCAOR) Dr Rasik Ravindra at Vasco-da-Gama in Goa, headed for Norway from New Delhi.

Informed sources told UNI today the scientists will reach the research base--Nyalesund, situated 1200 km from North Pole and 79 degrees north of the equator among a group of islands called Svalbard.

They will reach the place from Oslo via London and camp there for about a month to undertake experiments on climate changes,earth sciences and microbiology.

The Expedition is being undertaken in collaboration with Norway under the ''Svalbard Treaty'' signed in the 1920's.

It mightbe recalled that the union ministry of Earth Sciences had given the green signal to scientists to undertake the Arctic Expedition last year as NCAOR celebrated its silver jubilee of the Indian Expedition to the Antarctica which it launched in 1981.

It had also decided to explore the Southern Ocean even as several countries continued their expeditions for many years both in theArctic and the Southern Ocean, revealing startling information onbi-polar sciences.

Negotiations with the Centre were still underway on its expedition to the Southern Ocean, which will be undertaken after acquiring what was termed as ''ice-class vessel'' of our own instead of depending on Russia and other countries for such expeditions in the icy continent.

The debut Arctic Expedition by Indian scientists was expected to enrich the treasure of knowledge on polar sciences, which provide a key to secrets of the origin of the earth and the life around, scientists said.

The other scientists of the expedition team, apart from DrRavindra included Dr S Shivaji, deputy director, Centre forCellular and Molecular Biology (CCMB), Hyderabad, Dr Dhruva Sen Singhof the university of Lucknow, Dr S M Singh of NCAOR and Dr C GDeshpande, IITM, Pune.

Meanwhile, buoyed by the Larsemann Bay site clearance for locatingthe third Antarctic Research Base Station, 600 km east of thepresent site Maitri in Antarctica, the NCAOR scientists had now beenengaged in ''baseline data'' collection.

It might be recalled thatIndia had hosted for the first time the high-level Antarctic TreatyConsultative Meeting (ATCM) in New Delhi last April. It had given clearance to the proposed site for building the thirdresearch station in Antarctica, which could come up in two years once the work begins.

The scientists, however, continued to collect various data onbiology, geology, lake sediments and geographical mapping at theLarsemann Bay.

To begin with, the Arctic team will work at Ny-Alesund in collaboration with the Norwegian Polar Research Institute, for a period ranging from two weeks to four weeks during August and September.

It will initiate projects on Arctic microbes as work horses of biotechnology, measurement of atmospheric aerosols and ions in theArctic region, and Earth Science studies at Svalbard.

In the second phase, beginning February 2008, the Indian scientists will start work on four projects - Snowpack production of carbon monoxide and its diurnal variability, Sea ice microbial communities project, Carbon-cycling in the near-shore environments of Kongsfjorden and
Understanding the link between the Arctic and tropical Indian Ocean climatic variations.

At present, eight countries-- Norway, Germany, France, Britain,Italy, the Republic of Korea and China-- have their research stations for Arctic research at Ny-Alesund. UNI/BM/

Parliamentary Panel Pulls UP S&T Ministry for Dalays

2007-05-06T04:05:00.000-07:00

New Delhi, May 2-2k7 (UNI) A Parliamentary panel has pulled up the Science and Technology Ministry for dilly-dallying in implementing the programmes relating to Ocean Science, dubbing the delays as ''serious instances of bad planning and management''.

''Same old excuses have been given for disproportionate variationsin the utilisation of allocated funds under various programmes,''says the Standing Committee on Science and Technology, Environmentand Forests, in its 173rd Report.

The Ministry informed the Committee that during 2006-07, onlyRs 85.54 crore could be spent on Indian Meteorological Departmentagainst the Budgetary provision of Rs 105 crore due to delays inprocurement of DCWDS, automatic message switching system (AMSS) andtelecom facilities at field stations.

For tsunami and storm surge warning system, Rs 56 crore werespent against the allocated Rs 95 crore. The savings, the Ministrysaid, was due to delay in finalisation of hardware and softwarerequired for the programme.

Similarly, Rs 47 crore were used on the National Institute ofOcean Technology against Rs 87 crore. The variation was due to delayin commissioning the operation of barge-based desalination plant andin obtaining clearances for acquisition of land towards developmentof sea front facilities.

Advising the Ministry to avoid such administrative delays, theCommittee says it should strategically plan all its activities andaspire for timely implementations of all major projects. The panel has also pointed to the stagnation and lack of avenuesin scientific fields, and has advocated a comprehensive programmethat will have a positive impact on the scientific fraternity.

It has appreciated the research work carried out in Antarctica,and asked the Ministry to undertake every possible institutional andlogistic activity to establish the third permanent Indian Base inthe Larsemann Ranges. It has also recommended that the two new schemes-- Expedition toArctic and Ice-class Research Vessel-- proposed in the XIth FiveYear Plan, should be pursued in a well-planned manner.//EOM//

Bhatnagar Awardee's Cancer Research Dubious:Evidence

2007-05-06T03:59:00.000-07:00

By Yashovardhan Joshi
New Delhi, May 6-2k7 (UNI) The controversial Kundu papers on cancer research, which were cleared by a government committee, have now been found to be dubious by a body of eminent scientists.

The Society for Scientific Values (SSV), a watchdog of ethics andvalues in Indian Science, has found clinching evidence that the 2004Bhatnagar awardee Gopal Chandra Kundu and his coworkers are primafacie quilty of misconduct for falsification and fabrication of datain their research papers.

Through its independent investigation, the results of which havecome out this week, the SSV has found that Dr Kundu and hiscoworkers from the National Centre for Cell Science (NCCS), Punefraudulently reused the same data within Paper 1 and Paper II once,and from Paper I and Paper II five times.

''Our own consultations with independent experts, including adigital image analyst, indicate that the similarities between thefigures are too substantial to be dismissed as superficial,'' SSVPresident K L Chopra, a former director of IIT, Karagpur, told UNI today.

The prestigious American Journal of Biological Chemistry (JBC),which published the two research papers-- on interaction of proteinsin a particular cancer-- also found the reuse of data from one paperto another, and withdrew Paper II from its publication in Februarythis year.

The two independent parallel investigations by the JBC and theSSV have, thus, come to the same conclusion about misconduct by theauthors of the two papers, bringing into question the reliability ofthe government inquiry committee, headed by Prof G Padmanabhan,which exonerated Dr Kundu and his coworkers of all the charges.

''In the light of these findings, Dr Kundu must take most of theblame for the misconduct as head of the group, and the authoritiesconcerned should seriously reconsider their position in this caseand take exemplary action against all the authors,'' Dr Chopra said.

''Any disproportionate punishment of the students/post-doctorswhile shielding the senior scientists will open up new issues of injustice,'' he added. In fact, an internal inquiry conducted by NCCS, on the e-mailcomplaints of its two students in May June last year, had found Dr Kundu and his coworkers guilty and sought withdrawal of the JBCpapers.

Dr Kundu confessed in writing about the problems in thepapers and agreed to their withdrawal. It was only after he retracted his confession and accused thecommittee of extracting a confession from him under duress that thePadmanabhan inquiry committee was appointed.

The SSV came to know of the two inquiries after Prof Sonan PModak, a former member of the Governing Council of NCCS, made asigned complaint to it. ''The SSV then made several requests for the official record ofthe internal inquiry, but the requests were never answered,'' DrChopra said.

It was during his e-mail interaction with the Society that DrKundu accepted that he had confessed in writing but said theconfession was made under duress. ''We regret the lack of response of the Secretary, Department ofBiotechnology to our queries for six months, and the failure of theNCCS Director to provide information to us regarding the findings ofthe first committee appointed by him, even though he readily sentthe report of the second committee,'' the SSV President said.

''It is extremely important for the NCCS and the Department ofBiotechnology to repair the damage done to the reputation of Indianscience and prove their commitment to research integrity andscientific values through exemplary action,'' he said. The Society also requested the scientific community to develop arigorous, analytical and quantitative scientific method fordetection of image manipulation beyond any doubt and make it widely available.//eom//

Scientists for Unlocking Ancient Tide Guaging Technique

2007-03-15T09:05:00.000-07:00

BY: Dr.Y.Bala Murali Krishna

Panaji,Mar 14-2k7(UNI) There is every need to unlock the secret of predicting the crest and trough of ocean tides expertised 4000 years ago by marine engineers at Lothal in Gujarat's Gulf of Cambay, says director of the prestigious National Institute of Oceanography(NIO) Dr.Satish Shetye here.

It is the only place in the country where the tides reach as high as 10 metres and the engineers of the shipyard there knew how to predict the natural phenomenon of high and low tide with precision so that they could allow the ships into the sea or anchor out, he said.

Their ancient wisdom, which had remained a secret since 2000 BC, needs to be explored by the modern ocean scientist with tremendous applications in physical oceanography, Dr.Shetye, himself a top physical oceanography expert observed.

He was addressing the people at the Goa Science Centre in connection with the inauguration of the Goa chapter of the "Vidnyan Parishad", a unit of the Vijnana Bharati championing the promotion of "Swadeshi Science Movement" in the country.

The lunching of the chapter coincided with the birth day of physicist Albert Einstein.

Dr.Shetye also underlined the need for unravelling the science behind the technique of allowing sea water into "Khazan Lands" in Goa where agriculture and aquaculture had been practised side by side successfully for more than 1000 years.

Expressing concern over "rapid decline of Khazan Lands" in the current socio economic conditions, the NIO chief called for exploring the sophisticated tools used for controlling the tides used for promoting the dual culture. Careful recording of nature was a central theme in ancient India and it should be preserved for future, he said.

"Ability to learn gives us ability to earn in the knowledge economy. We have to make use of the ancient wisdom and modern knowledge capabilities with confidence," he said.

Earlier, Prof.K.I.Vasu, president of Vijnana Bharati,explained how Swadesi Science Movement had been striving for promoting ancient and traditional science along with modern science among the masses.

India's contribution to science since ages had been tremendous and continuous whereas there was a vacuum from 2C BC till 15th century AD in the West.There was need to translate the ancient wisdom into applications in modern days, he said.

Vedas, he said, contained roots of sciences including engineering and technology and the Vijnana Bharati's thrust was to expose them to the public particularly the youth.

In this connection, he recalled glorious contribution of scientists like CV Raman,Ramanujam, Aryabhatta, Charaka and Sushruta besides Bose and Y.Subbarao and Patanjali.

Organising Secretary of the Parishad Mr.A.Jaykumar stressed the need for popularising sciences through "regional languages" and with this mind, the parishad had started organising science congresses in regional languages to go to the masses involving scientists and communicators.

He also asked the Centre to ensure that the IIT products should compulsorily serve India for at least ten years to realise the dream of making India a developed country the year 2020 as envisioned by President Abdul Kalam.

President of Vidnyan Parishad Dr.Arvind Untawale said the Parishad was contemplating to work for revival of "sacred grooves" of Goa and rich biodiversity besides organizing Ayurvedic camps and vedic mathematics classes for students as part of its activities in the near future.

Dr.Shetye later distributed prizes to students who participated in the All Goa Science Talent Search Examination for junior and senior high school students. //EOM//

NOTE Dashes Letter to PM on Novartis Issue

2007-02-26T22:55:00.000-08:00

National Organisation for Tobacco Eradication (NOTE-India) general secretary Dr.Sekhar Salkar has today expressed its grave concern over the Swiss pharmaceutical company Novartis' legal action in the Chennai High Court challenging the "Glivec patent rejection and critical public health safeguards of Indian patent law".

In a letter to prime minister Manmohan singhji,he sought his intervention to safeguard the public health and India's patent law that have a very real impact on the lives of millions of patients - not just people living with HIV, but those living with cancer, asthma, heart disease, mental illness.

He pleaded for Singh’s continued support for access to affordable medicines and treatment and commitment to the constitutional guarantee of health and life.

Novartis is not only arguing to re-open the Glivec patent examination but also seeking a declaration from the high court that section 3(d) of the Indian Patent Act is not in compliance with TRIPS and that it violates Article 14 of the Indian Constitution. Section 3 (d) is the provision that protects against extension of patent monopolies on essential medicines.

Novartis sells Glivec, a life saving medicine for patients suffering from ‘Chronic Myeloid Leukemia’ at prohibitive prices of Rs 1.20 lakh per month to be taken almost life long. At the same time Indian companies give the same medicine for Approximately 11 to 12 thousand a month which is affordable for some patients and they can live a fruitful life

The price of Glivec, is well beyond the capacity of most patients. Novartis is aware that only a very small percentage of patients in India can afford this drug. Access to health care and medicine depends on solutions at various levels. It is our duty to try and remove barriers to the best of our ability.

On the issue of constitutionality of the Indian patent law, the government s constitutional expert, the Solicitor General of India was not present in court on February 15 and 16 at the time of arguments. In the absence of the government’s legal expert on constitutional matters, Indian parliament’s patent law and patient groups access to affordable medicines is at stake.

”We trust that the Solicitor General has now been authorized to take up this matter and will be in the Chennai high court defending the sovereign right of the Indian parliament to safeguard the health of its people and patients across the world,” Dr.Sekhar said.

We look forward to your continued support for access to affordable medicines and treatment and your commitment to the constitutional guarantee of health and life.

Note India strongly support Indian Cancer Society and other NGO’s in convincing Indian Government to fight in the court with constitutional experts so that the patients suffering from ‘Chronic Myeloid Leukemia’ receives medicine at cheaper rates. This judgment is likely to have consequences in the long term on many other medicines which are essential for the treatment of many types of Cancer. UNI/BM/

India to host Antarctic Treaty Consultative Meeting in Delhi

2006-12-03T01:28:00.000-08:00

BY: Y.Bala Murali krishna
Panaji,Dec 3-2k6(UNI) In a significant development, India is hosting the crucial Antarctic Treaty Consultative(ATC) Meeting for the first time in New Delhi even as the apex body is to clear the site for the proposed third Indian Research Base Station at Larsemann's Bay, 600 nautical miles east of the existing Maitri station in the icy continent.

"We are hosting the 15-day ATC meeting for the first time in New Delhi during March-April next in which about 300 delegates connected with the Antarctic research would participate," Dr.P.S.Goel,secretary, Union Ministry of Earth Sciences told UNI.

Meanwhile, Indian polar scientists are busy preparing a "Comprehensive Environment Evaluation Report(CEER)" for submission to the "Committee on Environment Protection(CEP)" which is to clear the report before its ratification by the ATC for setting up the third research station at Larsemann's Bay.

The report had to be circulated to all the member countries of the ATC for their comments/guidelines if any for modifiction/changes in the site plan as the site involved many aspects of preservation of ecology and environment at the Larsemann's Bay.

"Though some countries like Australia and New Zealand which dominate the area are initially opposing the idea because of 'terrotorial claims'.There would not be any problem for India to get the site clearance for the new research base station," says Dr.Rasik Ravindra,director,National Centre for Antarctic and Ocean Research (NCAOR),Vasco-da-Gama,Goa.

If everything goes well and clearance obtained, it would take at least 2 years for setting up the research base station at Larsemann's Bay. We have already floated quotations for the design of the state-of-the-art station," he said.

The prestigious NCAOR is the nodal agency for undertaking and coordinating the multi-disciplinary Indian Antarctic expeditions besides setting up of the third research station.

"They donot oppose the proposal but seek details regarding waste disposal at the proposed site probably to drag on the issue. But we are ready with all our explanations to maintain the ecology at the proposed site at the Larsemann's Bay," says NCAOR's logistics director Dr.T.V.P.Bhaskara Rao.

India had undertaken its first Antarctic Expedition in 1981 under the stewardship of the noted polar scientist Dr.S.Z.Quasim and later set up its first research station base "Dakshin Gangotri" in 1983.

The second base research station "Maitri" was later set up in 1988-89 following the caving in of the first one as it was located on an ice sheet.

The third one was necessiated for intensifying the polar research in the icy contineut even as India had decided to set its foot on the Southern Ocean with research proposed in the Arctic continent next year.

India had also proposed to acquire a state-of-the-art ice-class vessel at a cost of about Rs.400 crores next year for its research activities instead of depending on vessels chartered from other countries.

India, according to Dr.Rasik Ravindra,had during the last 25 expeditions had contributed 500 research papers to various prestigiouis international journals besides sending 1000 scientists from various disciplines to the icy continent for undertaking multi-disciplinary research since inception.

Only last month end, the NCAOR had flagged off its 26th Indian Antarctic Expedition in batches for the first time by flight through Capetown in South Africa to undertake research.Another batch is due to leave for the icy continent any time this month.

Research in the icy continents had been attracting many countries,the latest being Malaysia, among the 30 countries. Besides India,China,Japan and South Kores were the only countries from Asia participating in the Antarctic research.

The study of the ice-core shelf and lake sediments, flora and fauna besides the auroras,seismic changes and glaceology enables the scientists to study the climatic changes of the past millions of years.

This in turn help them collect,codify and collate data on the factors responsible for the past climatic changes so that they could generate cilmatic models to predict future climatic changes in the world. //EOM//

XXVI Indian Antarctica Expedition flagged off from Goa

2006-11-26T09:08:00.000-08:00

By: Y Bala Murali Krishna

Vasco-da-Gama, Goa, Nov 26-2k6: The XXVI Indian expedition to Antarctica took off today through Capetown to undertake climate studies using ice-core shelf besides upgrading the sophisticated facilities of the seismology and global positioning systems at the Maitri research station base in the icy continent.

''For the first time, we have flown our scientists from Capetown through a special arrangement with Antarctic Logic Consortium International of Russia, which operates flights to the icy continent,'' said Rasik Ravindra, director of the prestigious
National Centre Antarctic and Ocean Research (NCAOR) here.

Talking to the visiting UNI correspondent before flagging off the expedition, the NCAOR chief said the organisation used to fly the scientists from Mumbai to Capetown from where they set sail to Antarctic by a special ship taking about 20 days.

''Now that summer had set in the Antarctic, we have decided to fly the team allowing for early research activities and faster reach,'' said Mr Ravindra, who was the leader of the first winting team of the Indian expedition to Maitri station.

A batch of nine top scientists are now flying to the Capetown today, while another batch of 14 including logistics, scientific and technical experts from the Indian Army on deep drilling mission, had left the previous week.

In all, 50 scientists would be working in the expedition. Others would, however, reach the Antarctic through the ship from Capetown later this week for different missions.

The study of the ice-core that contains of signatures of the climate of the last thousands of years through its entrapped gases of the past atmosphere, was one of the core research activities of the NCAOR.

They had already brought ice-core, drilled 210 metres deep of the shelf, and started studying it at the state-of-the-art Ice-Core Laboratory set up in the NCAOR here.

Significantly, the scientists detected presence of about half a dozen microbes in the ice-core, which had now been analysed with the help of the Centre for Cellular and Molecular Biology, Hyderabad for strategic applications.

The task of reaching the icy continent became easier using Russian flights, with India joining the ''DROMLAN'' network, a consortium of 11 exploration countries, claims Mr Ravindra.

The Russian flight from Capetown takes just 6 hours to reach Antarctic and the India's Maitri research station was located just 8 km away from the airstrip of Central Droning Maudland in Antarctica,he said.

India had set sail to unravel the mysteries of the icy continent first in 1981, headed by top scientist and visionary S Z Quasim. The first research base station ''Dakshin Gangotri'' was set up in 1983.

The second station Maitri was set up in 1988-89, when the first station caved in due to vagaries of nature in the icy continent as it was located on an ice sheet.

Efforts were now underway to set up the third research base station 600 nautical miles east of Maithri at Larsermann Bay on a plateu. The experts had now been finalising the draft for obtaining clearance of the site by the Apex Antarctic Treaty Consultative Committee.

For the first time, the current expedition included specialists from the Border Roads Organisation (BRO) for assisting the logistics. The multi-disciplinary research involved about 30 institutions including the Defence Research and Development
Organistion (DRDO).

Others included Birbal Sahani Institute of Paleobotony, National Geophysical Research Institute, Geological Survey of India, Indian Institute of Geomagnetism and Sriram Institute for Industrial Research, Indian Mteorological Deprtment, Centre for Cellular and Molecular Biology and Annamalai University.//EoM//

Policies needed for sharing remotely sensed data among nations

BY: Y.Bala Murali Krishna

Panaji, Nov 12,2k6:Indian Space Research Organisation(ISRO)'s chairman G.Madhavan Nair has called respective nations for evolving policies so that the remotely sensed satellite data on earth observation could be shared,analysed and utilised on real time basis for mutual benefit with an integrated approach.

The ISRO chief had also pleaded with the scientists to develop high-resolution sensors/detectors for placement on earth,ocean and skies to collect data to monitor depletion of rare gases like Ozone and Nitrous Oxide that leave a signature on the imminent atmospheric changes for sharing.

"Unfortunately,many governments do not allow sharing of the real time data collected from the satellites and other monitoring mechanisms. We need to evolve policies that allow us to share the data on earth observation for various purposes including
drought,cyclones and weather monitoring," Dr.Nair said.

He was delivering the keynote address in the inaugural session of the fifth biennial Asia Pacific symposium on 'Remote Sensing for Resource Management and Disaster Warning and Mitigation' attended by about 600 delegates from across the world here today.

It was being organised for the first time in India on the precincts of the prestigious National Institute of Oceanography (NIO) here under the aegis of the International Society for Optical Engineering (SPIE), USA.

The scientists including Dr Upendra Singh from National Aeronautic and Space Administration (NASA), USA, and several others from Japan, China, Australia, Russia, France, UK, Germany, Sri Lanka and India and students were participating.

It was sponsored,among others,by the ISRO,Japan Aerospace Exploration Agency (JAXA),Japan, Natiojal Atmospheric and Oceanic Administration(NOAA)mUSA,National Institute of Information and Communications Technology(NICT),Japan,National Polar-orbiting Operation Environmental Satellite System integrated Programme Office
and Science Tecnology Corporation,USA.

The ISRO chief had disclosed that the final pase of the development of National Disaster Management Support System,now underway,would be completed this year so that data through dedicated and secure systems was made available for use in disaster management operations.

At the sametime, Dr.Nair had called for upgrading technologies through analytical models for earth monitoring so that data on droughts, cyclones and other diasters like the recent Tsunami could be obtained on real time basis.

The ISRO, he said, had contributed significantly for space research with applications on many aspects of life,over the last 25 years through launcing of its INSAT series of satellites.

The efforts were being stepped up in the realm of earth observation from space platforms the importance of which had increased recently for analysing data on national natural resources that help us understand the climate changes for disaster mitigation, he said.

Inaugurating the symposium,governor S.C.Jamir pleaded with the authorities to make available the satellite images cheaper to help the governments and even NGO's could to make plans for national and regional level development. He had also called for developing simple devices that could best be used in all educational programmes.

Dr.A.S.Kiran Kumar,belonging to the electro optical systems department at Ahmmedabad-based Space Applications Centre said the 58th International Astronautical Congress would be held in September next at Hyderabad in collaboration with the ISRO and the Department of Space.

Dr.Upendra N.Singh, belonging to the NASA said the scope of the symposium includes global environmentalchnge and its human dimension, disaster prediction, tracking and mitigation, enabling remote sensing technologies, present and future, and natural
resources management and sustainability.

The event brings together policy makers, scientists and engineers from across the world for sharing knowledge and ideas on these issues in the backdrop of latest developments in remote sensing technologies for societal benefits and socio ecpojomic
payoffs,Dr.Upendra added.//eom//
