Solar distillation is an age old practice. But Terry Thomas of Kerala has devised a simple and inexpensive apparatus which can supply a family's daily potable water needs for just Rs.3000. The simple 'window-like' apparatus or 'still' is made of aluminium and glass and is light weight. Each panel costs …
Nitrogen Oxides produced by huge fires and fossil fuel combustion are a major component of air pollution.They are the primary ingredients in ground-level ozone, a pollutant harmful to human health and vegetation.But new research led by a University of Washington atmospheric scientist shows that, in some regions, nitrogen oxides emitted …
us scientists have found an ingenious use for empty plastic bottles. Instead of disposing them in landfills, the non-biodegradable waste can be used to make engine oil for cars, say researchers at the University of Kentucky and the Chevron Energy Technology Company. They converted the plastic bottles into high-grade oil, …
deep sea genetic resources need to be protected from excessive commercial exploitation for pharmaceutical or industrial applications, warns a report by the United Nations University
owing to rising temperatures due to global warming, the Parbati glacier in Himachal Pradesh is melting fast. A study of satellite images shows the glacier has retreated by 578 metres between 1990 and 2001, a decline of almost 52 metres per year. This is bad news, as the glacier is …
On the site of a former hat factory in Danbury, Connecticut, a stand of genetically altered cottonwood trees sucks mercury from the contaminated soil.Across the continent in California, researchers use transgenic Indian mustard plants to soak up dangerously high selenium deposits caused by irrigation of the nation's bread basket. Still …
From fossils of thecamoebians, scientists know that Uttarkashi and Kedarnath areas in Uttaranchal were once covered by glacial lakes. This group of Thecamoebians are predominantly found in arctic ice cores. They are known to survive the freezing temperatures of the arctic. GSI Geologists recovered them at altitudes ranging between 1200 …
Thousands of marine species are at risk from global warming because of acidification of the world's oceans, scientists said. Britain's Royal Society said in a report that the seas were currently absorbing one tonne of carbon dioxide -- the prime greenhouse gas -- per person per year and were simply …
Scientists at a Pune lab have found a way of producing cheap and clean drinking water from contaminated water by using a membrane as filter. The device does not depend on electricity as most other water filters do and can thus be used in remote rural areas as well as …
Thousands of marine species are at risk from global warming because of acidification of the world's oceans, scientists said. Britain's Royal Society said in a report that the seas were currently absorbing one tonne of carbon dioxide -the prime greenhouse gas - per person per year and were simply running …
Global temperatures in the future could be much hotter than scientists have predicted if new computer models on climate change are correct, researchers said. Improvements in air quality will lead to a decrease in aerosols, small particles in the atmosphere that act as a brake on the impact of greenhouse …
Fluoride in tap water can cause bone cancer in boys, a disturbing new study indicates, although there is no evidence of a link for girls. New American research suggests that boys exposed to fluoride between the ages of five and 10 will suffer an increased rate of osteosarcoma
long hours of daylight enhance fertility of female adult Catla catla, a major freshwater Indian carp, claim researchers from West Bengal's Visva-Bharati University. They found exposing the fish to long photoperiods during the pre-spawning phase (April-May) increased the activity of vital chemicals and steroid enzymes known to aid ovarian growth. …
researchers from the Gauhati University, Assam, have developed a neem leaf powder (nlp) that acts as a dye remover and also helps get rid of heavy metals such as lead and chromium from solutions. "A small amount (1 gramme) of nlp could remove as much as 95 per cent of …
Climate change in Africa gave rise to modern humans. Now experts fear that global warming linked to carbon emissions will have its worst impact on humanity's cradle. "Africa is the most vulnerable continent to climate change', said Jennifer Morgan director of the Global Climate Change Programme at conservation group WWF. …
Lemon juice spruces up not only exhausted humans but car exhausts too, say researchers from the Institute of Catalysis and Petrochemistry in Madrid, Spain. Their report appeared online in Environmental Science and Technology recently. Catalytic converters of cars that run on diesel become inefficient after the vehicles are driven for …
pesticide levels thought safe for pollinators may prove harmful for the wild bee, says a Canadian study. It shows adult bumblebees exposed to significant levels of the pesticide spinosad during larval development have impaired foraging (food collecting) ability. In developed countries, about one third of human food depends on pollinating …
Over-exposure to carbon monoxide (C0) of low-level can cause damage to kids' ears leading to permanent hearing-loss.In a research conducted over rats, UCLA scientists have discovered how chronic exposure to low levels of carbon monoxide (CO) damages the inner ear of young rats, resulting in permanent hearing-loss. This study appeared …
Traffic jams can be more dangerous than you think. The vehicular fumes not only choke your lungs, ruin your skin and peak your stress levels, now doctors claim it can also bring down your fertility. After physiological imbalances and stress, pollution is emerging as the new-age contributing factor to low …
Climate change not the actions of humans, is likely to have led to the dying out of Australia's giant wombats, and kangaroos , according to a new study. Gilbert Price, who is studying for his PhD at Queensland University of Technology, has been analysing fossils found on a site at …
