Win some, lose some

to the dismay of many environmentalists, it seems that a potent ozone-depleting pesticide scheduled for a gradual phase-out would be retained after all. us researchers have found that emissions of the agricultural fumigant gas methyl bromide could be reduced to what they claim are insignificant levels by applying composted manure …

A hot planet is bad health

US researchers recently stated that climate change is most likely to have severe widespread impacts on human health with significant loss of life. The researchers also reported that global warming will put as much as 65 per cent of the world's population at risk of infection

Lobster casualties

An estimated US $2 million worth of lobsters were found either dead or ill off the coast of Maine in the US in 1998. Though some of these lobsters were found to have bacterial infections, researchers believe that the mystery infection is not bacterial. Maya Crosby, marine biologist with the …

Water lilies absorb heavy metal pollution

Recent experiments have shown water lilies to be capable of absorbing large quantities of heavy metals through their leaves and roots. The research was conducted by The Hebrew University of Jerusalem's Department of Agricultural Botany.

Sheryl Tittlemier's newfound chemical behaves like some of the nastiest industrial pollutants in the world and it comes from something natural in the oceans. Man-made pollutants …

Worst case scenarios

while leaders of some 150 countries were negotiating climate deals to curb global warming and climate change in Buenos Aires, Argentina, scientists were busy trying to figure out how global climate will change if the talks fail. Will it be a gradual change from warm to very hot, or a …

Cold diversity

the waters around Antarctica may be teeming with a far greater diversity of larvae than biologists realised. Researchers diving under the ice have discovered 10 times as many different types of larvae as were previously known to be there. They could provide a barometer to check the effects of climate …

Heat before the cold
