U.S. chemist Frank Raushel says he's using a $1.2 million federal grant to develop an enzyme that might neutralize a type of deadly nerve agent. Raushel, a professor at Texas A&M University, said he's focusing his research on neutralizing organophosphates, which initially were used as insecticides during the 1930s, but were soon being used during World War II as chemical warfare nerve agents. In 1988, an Iraqi Kurdish village was exposed to multiple chemical agents, killing about 5,000...

The U.S. Environmental Protection Agency has revoked regulations allowing residues of the pesticide carbofuran in food and drinking water. The agency said it is concerned about possible safety risks to young children. Carbofuran is a broad spectrum insecticide sprayed directly onto soil and plants to control beetles, nematodes and rootworm. The EPA said the greatest use of carbofuran is on alfalfa and rice, although it is also used on turf and grapes. Even though carbofuran is used on a...

Algerian scientists say they've found oregano oil works as well as synthetic insecticides to combat infestation by a common beetle found in stored cereals. The researchers say not only does oregano oil work well in fighting infestations of the beetle Rhizoppertha dominica, but it has none of the associated side effects of synthetic insecticides on the environment. Oregano, a member of the Lamiaceae family of plants, has been known to be a natural insecticide by apparently inhibiting egg...

A new study has found that Antarctica's Adelie penguins have recently been exposed to trace levels of the chemical DDT as a result of frozen stores of the pesticide seeping out of the continent's melting glaciers.The chemical's presence could indicate that other frozen toxins will be released as a result of climate change in the environment, according to Heidi Geisz, a marine biologist at Virginia Institute of Marine Science.  Geisz, who has worked in Antarctica since 1999, led the team...

WASHINGTON - The World Health Organization is poised to promote broader use of the pesticide DDT in the battle against malaria. Long banned in the United States because of environmental damage, DDT is used legally in a few impoverished countries to kill malaria-bearing mosquitoes. It no longer is sprayed outdoors, but indoors "” to coat the inside walls of mud huts or other dwellings where mosquitoes lurk. The aim is to protect sleeping families from bites at night. There has been...

By George Obulutsa NAIROBI (Reuters) - Researchers have developed an organic pesticide that can control deadly locust swarms in Africa, reducing the need to use traditional insecticides that harm the environment, a senior scientist said on Wednesday. Last year West Africa's worst locust infestation for more than a decade wreaked havoc and worsened food shortages in some of the world's poorest nations, causing major damage to grain crops across a region where many are subsistence...

NEW YORK (Reuters Health) - Although reported illnesses due to pesticide exposures at schools in the US are relatively uncommon, the incidence of such exposures among schoolchildren has increased in recent years, investigators report. There are no specific federal guidelines limiting pesticide exposures at schools, Dr. Walter A. Alarcon and colleagues note in their report in this week's Journal of the American Medical Association. To assess the magnitude of the problem, Dr. Alarcon, with...
