Lab rat debate

The Indian National Science Academy (INSA), an influential body of peers that advises the government on policy issues, has now observed that banning use of animals in labs completely might not be such a great thing after all. The academy has compiled a report that goes to India’s ministry of environment and forests next month.

The University Grants Commission (UGC) had suggested banning use of lab animals for research some time back. However, the draft bill that came in July last year was not taken very well by one and all. Subsequently, INSA held its own consultation sessions and found that completely eliminating the use of lab animals would be detrimental for life science and medicine students. Their line seems to be: “reduce use of animals in labs — yes, completely remove them from labs — no”.

Animal rights activists worldwide have been clamouring for the ban for long. Their suggestion — replacing animals with computer simulations and models — has not been received well by sections of science teachers in schools and Universities.

At least in India, it doesn’t look like we might have seen the end of the debate yet as it appeared when UGC released its guidelines last year.

Young astronomy

About a year and a half back in September 2010, this picture bagged top honors at the Astronomy Photographer of the Year competition in the under-16 category. The photograph will now make it to an official annual book on the competition held by the Royal Observatory of Greenwich, UK.

The picture shows an annular eclipse, which occurs when the Moon is too far from the Earth to completely cover the Sun’s disc unlike what happens during a solar ecplise. Through a layer of cloud, Dhruv shot the bright ring that appeared as the Sun shone around the edges of the Moon.

The young photographer

“My father got me a telescope and a digital camera, and the annular eclipse was a perfect opportunity to test my skills. The photograph was clicked from the southernmost tip of the Indian Peninsula, Kanyakumari,” Dhruv, now 16, says. Dhruv’s father Arvind Paranjpye is an avid astronomy photographer himself and is presently the director of Nehru Planetarium in Mumbai. “Almost everyone had cameras attached to big telescopes with zoom lenses. While they were all disappointed that clouds had come in, he made full opportunity of the fact that clouds can act as natural filter,” the proud father says.

The photograph called ‘A Perfect Circle’ was taken with a basic 3.2 megapixel point-and-shoot camera, and got the first prize in that category. The stand out quality that got him the prize was the perfect geometry of the eclipsed Sun contrasted with the chaotic shapes of the clouds. By using the clouds as a filter, Dhruv was able to reproduce wonderful, contrasting colours.

This recognition would certainly motivate a lot of young astronomy enthusiasts and photographers to pursue their passion.

Booze buzz

A recently concluded global meet of cardiologists  — the World Congress of Cardiology —  in Dubai (April 18-21, 2012) discussed some interesting research stories from India. One among them was how Bollywood is impacting alcohol use among Indian adolescents.

Though the study is yet to be published in a peer-reviewed journal (it was peer-reviewed to be presented at the congress, the organisers said), it has found that overall 10% of students ( between 12–16 years age) surveyed had already tried alcohol. However, students who had seen their stars drink on screen were  about three times more likely to have tried alcohol as compared with those who were not exposed to these films.

G. P. Nazar  from Health Related Information Dissemination Against Youth (HIRDAY) — a voluntary organisation of health professionals and social scientists — who presented the study said while alcohol advertising is banned in Indian media and scenes glorifying or justifying drinking are censored out from Hindi films, there is no dedicated health legislation that prohibits the depiction of alcohol in these films.

This is ground enough for an immediate alcohol control policy, he said.

The study used 59 Bollywood movies to record the number of alcohol use occurrences and interviewed 3,956 adolescents on whether they had seen these movies. They were grouped according to their exposure level and then asked about their alcohol consumption status to arrive at the results.

In another study presented at the congress, not surprisingly, Indians have been found to be at a higher risk for cardiovascular diseases (CVD) than the CVD hotbeds of USA or Western Europe. Called the Indian Heart Watch (IHW) study, it looked at the prevalence of lifestyle and biological CVD risk factors across the country. The study took place over a five-year period (2006–2010) and involved 6,000 men and women from 11 cities across various regions of India

In this yet unpublished study, 79% men and 83% women were found to be physically inactive. Also, 51% men and 48% women were found to have high fat diets. Nutritional intake, alcohol consumption and smoking were also considered to assess the results. Biological and metabolic parameters such as weight, blood pressure, cholesterol and diabetic tendencies were also considered. Prakash Deedwania of the University of California, San Francisco, USA said these results must prompt the government to develop public health strategies that will change lifestyles.

The results show that there is low awareness of these risk factors even among literate middle-class urban Indians.

Satellite launch

This week, the Indian Space Research Organisation (ISRO) is all set to launch its radar imaging satellite RISAT-1 on board the organisation’s workhorse, the Polar Satellite Launch Vehicle (PSLV).

Early on April 26 morning, RISAT-1, a microwave remote sensing satellite carrying a synthetic aperture radar (SAR), will be launched into space. RISAT-1 weighs around 1858 kg — the heaviest satellite to be lifted by the PSLV thus far — and is scheduled to be put into a 536 km orbit, according the ISRO chairman K. Radhakrishnan. It’s life span is five years.

The 71-hour countdown for the launch of  started this morning at the Satish Dhawan Space Centre at Sriharikota in Andhra Pradesh.

India currently depends on images from a Canadian satellite as its domestic remote sensing spacecraft can’t take pictures of the ground during cloud cover. RISAT-1 being launched at a mission cost of Rs. 498 crore  will operate in a multi-polarisation and multi-resolution mode to provide images with coarse, fine and high spatial resolutions. Pictures beamed from RISAT-1 would be used to estimate crop yield, assess acreage and predict crop health during monsoons, when the sky is covered with clouds. The images can also be used for disaster management during cyclones and floods.

ISRO had launched RISAT-2 in 2009 with an all weather capability to take images of the earth. The satellite was aimed to enhance ISRO’s capability for disaster management applications.

PSLV-C19 was launched into space from Sriharikota early this morning (April 26, 2012) putting RISAT-1 in a polar circular orbit. It was a successful lift-off, according to ISRO chairman K. Radhakrishnan.

RISAT-1 will start beaming images in five days.

Notably, PSLV C-19 is the third in this series of launch vehicles to involve the high-end version PSLV-XL (XL meaning extra large). It is equipped with six extended strap-on motors, each carrying 12 tonnes of solid propellant. ISRO’s Chandrayaan-1 was also launched on board a PSLV-XL.

Royal fellows

This year’s fellows for The Royal Society — one of the most coveted fellowships in the world of science — announced today, include six names of Indian origin. The fellowship is made up of the most eminent scientists, engineers and technologists from the UK and the Commonwealth. It boasts of more than 80 Nobel Laureates among its fellows.

This year’s list features, right on top, Varinder Kumar Aggarwal, a professor of synthetic biology in the University of Bristol. Born in North India, Aggarwal did all his science in the UK where he studied and worked all his life. In awarding him the fellowship, the society has acknowledged his  “productivity and breadth (that) make him one of the foremost organic chemists of his generation and one who is very widely recognised internationally”.

Like Aggarwal, Shankar Balasubramanian, a professor of medicinal chemistry at the University of Cambridge and a senior group leader at the Cancer Research UK, Cambridge Research Institute also left India as an infant. Born in Chennai (then Madras) he is an internationally recognised leader in the field of nucleic acids. The society makes special mention of his leading next generation sequencing methodology, Solexa sequencing, that makes routine, accurate, low-cost sequencing of human genomes a reality and has revolutionised biology.

However, the true blue Indian in the coveted list is Krishnaswamy Vijayraghavan, a senior professor and Director of the National Centre for Biological Sciences, Bangalore. An alumnus of the Indian Institute of Technology Kanpur, Vijayraghavan has “worked to establish new institutions, drawing the best young scientists to India”. Under his leadership, NCBS has indeed evolved into a world-class institution. He has been recognised by the society for being an “outstanding developmental geneticist”.

Mathematician Chandrashekhar Bhalchandra Khare, who was featured in this blog when he bagged the Infosys Prize for 2010, started his career with the Tata Institute of Fundamental Research in India and later moved out of the country. Presently he works as a professor in the department of mathematics, University of California, Los Angeles. He  has been called an ‘extremely original mathematician’ studying the relationship between Galois representations and modular forms. His forte is finding ingenious but relatively simple new ideas, The Royal Society notes.

Guntur-born Mathukumalli Vidyasagar studied and worked in the US through his adult life. Vidyasagar, born in the year of Indian independence, has made outstanding contributions to the control and systems theory and statistical learning. He has combined probability theory, combinatorics, and artificial intelligence to produce a beautiful unified theory of statistical learning.

Particle physicist Tejinder Singh Virdee of Imperial College, London is distinguished for the design, construction and exploitation of the huge CMS experiment at the CERN Large Hadron Collider on the Franco-Swiss border.  He originated the concept of CMS with four colleagues around 1990 and there are now over 3000 participants from 38 countries. He now concentrates on the search for the Higgs boson.

Congratulations to all the new fellows! They now share their fellowship with the likes of Sir Isaac Newton, Robert Boyle, Charles Darwin, Sir Alexander Fleming, Dorothy Hodgkin, Stephen Hawking, Sir Ernest Rutherford, Sir J.J. Thompson, William Thomson (Baron Kelvin) and Sir Christopher Wren.

Nice ice

In an interesting paper published in Nature Geoscience this week, scientists studying the glaciers in the Karakoram mountain range along the Sino-Indian border suggest that the ice masses there are actually growing contrary to the ‘glacier waning’ phenomenon elsewhere in the world.

Based on satellite images, they say that some of the glaciers in the central Karakoram range, spread across China’s borders with India and Pakistan, are gaining thickness.  The researchers measured thickness of the glaciers in more than 5,500 square kilometre are and compared them with previous satellite data. They have reported an ice thickness which when melted would yield 11 centimeters of water. Though not an enormous change,  this reverse trend despite the scare of global warming is surprising and perhaps happy.

The researchers, however, have no clue yet on why this might be happening. Another group of scientists working in the Karakoram range had hinted in 2005 that the ice masses there might be growing. But it wasn’t clear then if the glaciers in the region were spreading to cover more area and making the ice thinner.

The Himalayan glaciers had hogged headlines in 2010 for the wrong reasons when an erroneous report by a working group of the Intergovernmental Panel on Climate Change had predicted that they we would see the end of them by 2035. The IPCC was, however, quick to correct its stand.

Here’s wishing our glaciers more health!

Arrest irks scientists

The arrest of an Indian molecular biologist on flimsy grounds has irked the scientific community of the country. Partho Sarothi Ray is under arrest and subsequent detention since April 8, 2012, along with some others for peacefully protesting against the eviction of slum dwellers in the West Bengal state capital Kolkata. He has been charged under a number of sections under the Indian Penal Code, which his supporters say hold no ground.

The arrest of the scientist with an enviable record — his science is rated among the best in this country as evident from the list of publications  — has been criticised by eminent scientists, colleagues and friends. The community has written to the Prime Minister Manmohan Singh to intervene in the matter and get Ray released. An online petition by a pro-people group had already amassed close to 900 signatures (and counting) from across the world.  Mriganka Sur, an eminent professor of neuroscience at Massachusetts Institute of Technology, who was  a member of a review committee of the Wellcome Trust-India Alliance that awarded Ray the prestigious Wellcome Trust-India Alliance Intermediate Fellowship in 2010, has also expressed concern over the arrest of the young life scientist.

In my personal interaction with Ray after one of his papers got published in Nature, this assistant professor at the Indian Institute of Science Education and Research (IISER) Kolkata came across as a scientist with a purpose and sense of societal responsibility. That explains his being involved in the cause for the downtrodden. His interesting work on a molecular solution to the ‘dilemma’ that cells face was featured in Nature India. 

We hope the mounting pressure on the government makes it take a fresh look at Ray’s arrest.
