The original application was registered suo-motu based on the news item titled "Nayar …
It sounds like something out of an old sci-fi movie. But the plasmatron, a device under development for several years at the Massachusetts Institute of Technology, may one day help reduce smog-producing emissions from cars and other vehicles. Researchers told a recent meeting of the American Physical Society that they …
The centre for Application of Science and Technology for Rural Areas is developing a water purification system using the bactericidal properties of silver which will provide clean and safe water at a low cost.Two prototypes of the system have been developed by Astra at the Indian Institute of Science, one …
A team of scientists is proposing a plan to cut Australia's greenhouse gas emissions by injecting carbon dioxide deep underground.The Commonwealth Scientific and Industrial Research Organisation (CSIRO), and Australian Petroleum Co-operative Research Centre (APCRC) are studying the geological disposal of CO2 in the Gladstone-Rockhampton region of Central Queensland which is …
the lush green Amazonian forests have always left scientists wondering how such a variety was possible. This ecological booty is almost three times more than the flora and fauna found in other parts of the world. Now, a new study, conducted by two American scientists, suggests that this diversity has …
it is easily available and a cheaper alternative to combat the deadly West Nile virus that struck New York city sometime ago: oil from summer cypress, an ornamental prized bush, can possibly save the day for all those trying to fight the virus. The bush might also provide a cheap …
a tree-dwelling African ant prunes branches of host trees to prevent stronger neighbours from invading their tree and ousting them. Crematogaster nigriceps is one of the four ant species that dwell in the Whistling Thorn Tree ( Acacia drepanolobium) in East Africa. However, competition for trees is fierce and Crematogaster …
Spiders probably use polarised light as a compass when they return home after foraging. Marie Dacke of the University of Lund in Sweden studied the spider Drassodes cupreus and found that two of its eight eyes have built-in filters that allow them to detect the polarisation of light. The animals …
it is a fight for survival for Southeast Asia's coral fish like groupers and wrasses. With plenty of people more than willing to pay a handsome price for these fish, Chinese restaurants are encouraging fishing to the point of endangering marine life. The World Wide Fund for Nature (wwf) in …
In order to power tomorrow's cars, researchers are scrambling to exploit the hydrogen-absorbing properties of carbon. Nobody really knows why carbon nano materials are good at storing hydrogen. Michael Heben of America's National Renewable Energy Laboratory, a pioneer in the field, believes that it is something to do with the …
Scientists have found that a species of pine tree thrives in the carbon dioxide-enriched air expected in the future, becoming reproductively mature earlier and producing more cones and seeds than identical trees living in today's CO2 concentrations.The researchers at Duke University, USA, have been investigating the effects of increasing CO2 …
Pearl project to detect pollutants using laster system. Three US universities have drawn up an ambitious project plan to develop a ship-based research laboratory with a high-power laser system to detect pollutants from natural and artificial sources and for a host of other applications including detection of chemical warfare agents, …
Ion Exchange (India) Ltd has came out with sullage recycling systems for the domestic sector, which it claims will help alleviate the perennial water shortage in cities. The company has earlier provided the technology to the industry for recycling waste water.
The public sector Bharat Heavy Electricals (BHEL) has taken a giant stride in developing technology to check air pollution through its indigenous "catalytic converter," a device attached to exhausts of automobiles to filter harmful gases, next only to a US company in the world.
A US professor has developed a process allowing difficult to dispose of sewage sludge to be turned into a combustible gas with a positive by-product, methane gas.Currently sewage sludge, the harmful of the two by-products of treating raw sewage, is incinerated using a substantial amount of fuel, as it is …
The world is beating a path to Edmonton's landfill site to see Dwayne Simmons turn garbage into dirt. They've come from China, Mexico, Japan, Scotland and a bevy of other countries to look at the northern Alberta city's new $100-million compost facility that Simmons manages for TransAlta, an Alberta utility …
Lantana, an exotic species brought to India as a decorative and hedge plant, may no longer be a 'pest', thanks to a Ford Foundation-funded project executed by the Forest Research Institute (FRI)) in Dehra Dun. Experts working at research centres in Haryana, Madhya Pradesh and Orissa, have succeeded in using …
NASA's Goddard Space Flight Center, Greenbelt, MD, will burn landfill gas to heat its buildings under a new contract awarded. "This project will prevent as much pollution as planting 68,000 acres of trees or removing 100,000 cars from Maryland highways by reducing harmful gases produced at the Center and the …
A system that was developed to plot the path of nuclear emissions following the Chernobyl disaster in 1986 could help to improve the monitoring of air pollution. The Name System, developed by the UK's Met Office, takes pollution emission data from across Europe and applies it to a computerised model …
A process called bio-remediation, in which microscopic bacteria clean contaminated soil and water, is proving useful as a method of protecting the environment. Ryuichiro Kurane, chief of the bacteria function department at the Industrial Science and Technology Agency, and Toshihiro Hoaki, vice section chief of Taisei Corp.'s natural environment department, …
