the decreasing snow cover in Southwest Asia and the Himalaya is threatening marine life in central and western parts of the Arabian Sea, which lie thousands of kilometres (km) away. According to a study published in Science (April 22, Vol 308, No 5721), reduced winter and spring snow cover in …
The London Underground might seem dusty and polluted but the air beneath the capital is safer to breathe than that on the surface. A new report suggests taking the tube might be better for the lungs than cycling or walking.The report published in medical journal Occupational and Environmental Medicine says …
A weed that spreads rapidly through ponds, lakes and rivers could provide a cheap yet effective way of removing arsenic from drinking water. A research team at UK's De Montfort University, led by Parvez Haris, has found a powder made from the dried roots of water hyacinth (Eichhornia crassipes) removed …
a recent study mapping the municipal solid waste (msw) produced and dumped in Guwahati, the chaotic capital of Assam, has shown its waste disposal system is getting choked and the city needs to quickly find a scientifically determined alternative to get out of the mess. The study used geographic information …
if people in Africa were to switch to charcoal as cooking fuel from wood, it would not only significantly reduce greenhouse gas (ghg) emissions but also save millions of lives, claim researchers. Led by Dan Kammen of the University of California, Berkeley, the scientists calculated the health and environmental effects …
salmon farms pose a massive threat of sea louse infection to wild populations of the fish, says a study conducted in a fjord in British Columbia, Canada (Proceedings of the Royal Society B, published online April 1, 2005). The researchers believe the results are also relevant to fish farms in …
a household arsenic filter has been developed under the Nepal Water Project, which not only removes the carcinogenic chemical but also pathogens, iron, turbidity and odour. The project is being implemented jointly by the us -based Massachusetts Institute of Technology (mit), the Nepal-based non-governmental organisation Environment and Public Health Organisation …
What do clothes and countries have in common other than the fact that both start with the same letter? Both can shrink, according to a US seismologist. Roger Bilham of the Colorado University in the US says Nepal is shrinking by 18 millimetre (mm) each year as a result of …
indian scientists have developed a simple and cheap technique to remove crystal violet (cv), a toxic dye used in lab experiments, from waste water. The researchers from the Indian Institute of Technology in Kharagpur used hardwood sawdust to trap (adsorb) the cv molecules. "We found 1 gramme (g) of sawdust …
Environmentalists pollutants from domestic and industrial waste and pesticides could be changing the ratio of sex chromosomes in sperm, researchers said. They found that Swedish fishermen exposed to high levels of organochlorine pollutants have a higher proportion of the male Y chromosomes in their sperm. But they do not know …
thanks to a new us study, the science of climate change may no longer be abused by nations to shrug off responsibility of reducing greenhouse emissions. Scientists from the Scripps Institution of Oceanography, and the Lawrence Livermore National Laboratory have produced the first clear evidence of human-produced global warming in …
firewood and other biofuels, such as animal manure and agricultural waste, used for cooking in India could be a potential trigger for climate change in the region, according to a study by an Indo-us team. But some Indian scientists have questioned the methodology adopted to arrive at the conclusion. The …
The immediate need to reduce vehicular emission levels has been brought out by a recent study which found that exposure of expectant mothers to combustion-related urban air pollution has the potential to alter the structure of foetus' chromosomes. Sixty newborns were studied before reaching this conclusion. Experiments done in the …
concerned at the urban air quality due to emissions from diesel vehicles, the Clean Air Initiative for Asia (cai Asia) sponsored a study in three typical Asian cities
scientists have deciphered the genome of Dehalococcoides ethenogens bacterium, which is the only microbe known to detoxify two of the most pervasive groundwater pollutants
Exposure to air pollution, even in the womb, may be linked to genetic changes associated with an increased risk of cancer, researchers said. That finding, from a study done in New York City by scientists at Columbia University, followed 60 newborns and their nonsmoking mothers in low-income neighborhoods, primarily in …
the area hit by severe drought worldwide has increased from nearly 12 per cent in the 1970s to 30 per cent in the early 2000s, according to scientists at the National Center for Atmospheric Research (ncar), Colorado, usa . Almost half of that change is due to global warming rather …
Reactions between smog and plant proteins could explain the mysterious increases in allergies. Exhaust fumes from traffic could be turning airborne proteins into more powerful allergens, explaining why asthma and other allergies are on the rise in urban areas. Researchers have found that the mixture of nitrogen dioxide and ozone …
