The original application was registered suo-motu based on the news item titled "Nayar …
Pilot studies conducted in a former mine-drainage tunnel were conducted at Leadville, Colorado, a part of the Rocky Mountains from which silver and other precious metals have been extracted. The study is reported in the specialist journal Ground Engineering. It found that nearly three quarters of heavy-metal contamination could be …
Researchers in the Faculty of Environmental Engineering and Science at the University of Illinois Urbana-Champaign have developed a device which captures and recovers dilute volatile organic compounds and other hazardous air pollutants.The industrial system which is about the size of a large filing cabinet, according to the researchers, comprises activated-carbon-fibre …
A little more green and white instead of black can help keep Louisiana's capital of Baton Rouge cooler, federal scientists say after analyzing infrared photographs of the city.A NASA-Environmental Protection Agency study showed that white roofs, lighter-colored pavement and trees providing shade to parking lots and streets can reduce heat …
A cost effective and eco-friendly construction material that could be an alternative to asbestos cement corrugated sheets has been developed by the Indian Plywood Industries Research and Training Institute (IPIRTI) in Bangalore.
In industries such as mining, farming and forestry, ants can help gauge the health of the environment by just crawling around and being antsy.And now it will be possible to do that more quickly and cheaply, thanks to a new technique developed by scientists from CSIRO. It has been recognised …
Researchers have come up with a way to use old tires and pistachio shells to remove mercury emissions from power plants. Activated-carbon adsorbents made from the tires and shells work as well as or better than current commercial products and might even be cheaper to produce, say researchers at the …
The fungus Armillaria ostoyae , commonly called the honey mushroom, has grown so extensively in Malheur National Forest, usa , that it has become the largest living organism ever found. The fungal spore seems to have germinated approximately 2,400 years ago and now covers an area of 890 hectares and …
Scientists have developed a new way of tackling global warming by feeding cattle a daily dose of bacteria to stop them belching out methane as they graze. Cows, and to a lesser extent sheep, are responsible for nearly a quarter of the global emissions of methane, a greenhouse gas. Contrary …
a team of scientists at Ohio University in the us is working on technology that uses algae, sunlight and the natural process of photosynthesis to absorb carbon dioxide ( co 2 ) from the combustion of coal. The result: reduced greenhouse gas emissions. co 2 has been identified as the …
Researchers in the us have found out that the nitrate in snow interacts with sunlight and sets off a very rapid series of photochemical reactions, producing oxides of nitrogen (no x ). "We found very high concentrations of no x in the snow of areas which are beyond the reach …
The number of wild and domesticated bees in the us has dropped considerably in recent years. In some parts of the country, nearly 90 per cent of the bees are estimated to have disappeared. "The biggest reason behind the decline is a bee-killing parasite, known as the varroa mite, which …
a team of us and European scientists have identified a new greenhouse gas that traps heat more effectively than all other known greenhouse gases. Trifluoromethyl sulfur pentafluoride ( sf5 cf3 ) is a synthetic gas and is 18,000 times more effective in trapping atmospheric heat as compared to carbon dioxide, …
a canadian researcher has discovered answer to one of the most crucial environmental challenges facing the world: how to save coral reefs. Ellsworth LeDrew, a geography professor at the University of Waterloo in Ontario, has devised a mathematical formula that will automatically scan satellite images to uncover changes in coral …
slash-and-burn farming practised by poor farmers in the Indian Northeast, known as jhum , is often said to be damaging to the environment. This traditional mode of agriculture has been discouraged through several measures. A recent study, one of the very few to scientifically assess the impact of jhum on …
there is no end to human wants and an evergreen tree is the latest prey of this. Prunus africana, a tree found only in Africa, may become extinct within 5-10 years. The tree is being cut down by the poachers just for its bark, which provides the best natural cure …
cement and steel production may be more energy efficient in many developing countries than in the us , according to a recent study published in Europe. Among the six countries studied, iron and steel production is reported to be the most energy efficient in South Korea, while Brazil, Mexico, India …
global warming is all set to play havoc with the world's transport systems. In the coming years, it will lead to traffic jams and delay train services, says Anthony Astbury, a scientist at Britain's meteorological office. According to him, the atmospheric temperature will rise by a further 3
Artificial plantations are generally monocultures, but in general forests, many species thrive. Why this should be so is one of those questions that is so obvious that people rarely bother to ask it. Alissa Packer and Keith Clay, of Indiana University, have however, not only asked it but believe they …
Norway's food safety agency has issued a warning to people in the north of the country to reduce their consumption of seagull eggs. The agency claimed the eggs are contaminated with high levels of toxic polychlorinated biphenyls ( pcb s). The people of Troms
