Cleaner groundwater

Scientists from the US Department of Energy (DoE) claim to have developed a cheaper and easier way to remove toxic contaminants from groundwater. The technique could be used to clean up military bases, chemical and petroleum plants and weapon production facilities. Researchers at the DoE's Pacific Northwest Laboratory said the …

Lawnful of pollution

do you know that each time you mow that beautiful lawn in front of your house, you are contributing to one of the biggest nightmares of urban living

Poisoned land

spain recently congratulated itself on saving Donana national park, one of the continent's most important wetlands, from a flood of toxic sludge from a mine. The celebrations, however, may be short-lived, for mining engineers and naturalists fear that land outside the park may have been contaminated with enough heavy metals …

Bugged

In the recent years, scientists have employed diverse means to protect the environment, among which bioremediation has shown great potential as an effective method to clean up toxic wastes. But how do we know whether the genetically-modified bacteria that are used in this process are doing their job or not? …

Food fighters

among all the myriad animal, bird and insect species that we share this planet with, one behavioural phenomenon that has always interested scientists is that of parent-offspring and inter-sibling conflicts. Common to almost all these species - including humans - it has never failed to generate curiosity among experts who …

Conservation kills

alarmed by the decline of certain species such as ibex, deer and chamois in the forests of the Alps through hunting, conservationists had urged governments to restrict all activities that would further endanger these animals and disrupt the natural ecology of the Alps. But now, they have discovered that it …

Edged to extinction

rainforests are one of the most severely threatened ecosystems on Earth today. Every passing year sees ambitious plans drawn up to prevent them from further degradation or preserve whatever little of them might be left. A new study, however, says that small patches of these forests may not be worth …

Hair oil

thanks to hairdresser Phillip McCrory from Alabama, usa, we now have a potential weapon against oil spills - those hair-raising environmental nightmares. Inspired by the media coverage of the 1989 Exxon Valdez oil spill, McCrory asked himself a very interesting question: if oil can coat animal fur readily, why not …

Venom variations

The venom of the Malaya pitviper Calloselasma rhodostoma , collected from Vietnam, Thailand, Malaysia and Java, shows considerable variations in its chemical composition. The pattern of variation is due to the changes in the diet of the snakes in these regions. Since the function of the venom is to immobilise …

Mussel bound

Invading zebra mussels have colonised at least 2,000 sq km of soft sediment on the beds of the Great Lakes in the US, says a recent report. Till now, it was thought that these mussels could grow only on hard surfaces. Paul Berkman of Ohio State University, USA, says his …

Laser to probe Philly sky in study of smog

A green laser beam will be shooting nearly two miles into the night sky above the streets of Philadelphia in an effort to study the smog and soot that plague cities. The $3 million urban atmosphere study funded by the US EPA has an aura of "Star Wars" and is …

U.S.'s Los Alamos finds way to cut chip waste

The U.S.'s Los Alamos National Laboratory said it has developed an environmentally friendly way of reducing water use and cutting toxic waste at chip manufacturing plants. The federal laboratory in Los Alamos, New Mexico, in conjunction with Hewlett-Packard Co., said it has figured out how to use carbon dioxide under …

Corals with stories

For years foresters and scientists have studied the rings found in treetrunks to determine the age of the growths. In a similar fashion, scientists are now scrutinising the rings lining coral skeletons. Since 1993, a team of Malaysian scientists have been cutting up corals,looking for traces of heavy metals. They …

Bacteria to clean up contaminants

Australian scientists are testing an improved technique for applying bioremediation to pollution problems. The researchers from CSIRO, the national research organisation, are treating groundwater contaminated with a common pesticide called atrazine in Perth.

Where green is also penny-wise

Using new technology developed by the Jamshedpur-based National Metallurgical Laboratory(NML), it is now possible to design eco-friendly melting furnaces which can convert the large number of foundries in and around Agra into less-polluting units. The system can also be replicated elsewhere in the country where clusters of foundries operate.
