A study released on Wednesday warned that one of the world's most common insect repellents acts on the central nervous system in the same way as some insecticides and nerve gases, AFP reported. Researchers say moderate use of the chemical compound deet is most likely safe, but experiments on insects, as well as on enzymes extracted from mice and human neurons, showed for the first time that it can interfere with the proper functioning of the nervous system. Many experts are urgently calling...

DEET, the active ingredient in many insect repellents, has been found to be neurotoxic in insects and mammals, French researchers reported Tuesday. Because of their finding, researchers are saying more investigations are needed quickly to either confirm or dismiss potential neurotoxicity to humans, the researchers said in a news release. We've found that DEET is not simply a behavior-modifying chemical but also inhibits the activity of a key central nervous system enzyme, acetycholinesterase,...

A study published this week in the open access journal PLoS Medicine finds no evidence to suggest that a controversial antidote recommended by the World Health Organisation (WHO) to treat patients poisoned with highly toxic insecticides improves their chance of survival. The results may even add weight to existing concerns about pralidoxime, the treatment recommended by the WHO, by suggesting that it could be harmful in patients who have deliberately poisoned themselves with...

 The cause of Parkinson's disease (PD), the second most frequent neurodegenerative disease after Alzheimer's disease, is unknown, but in most cases it is believed to involve a combination of environmental risk factors and genetic susceptibility. Laboratory studies in rats have shown that injecting the insecticide rotenone leads to an animal model of PD and several epidemiological studies have shown an association between pesticides and PD, but most have not identified specific pesticides...

The U.S. Environmental Protection Agency has revoked all regulations permitting small amounts of the residue of carbofuran in food. The EPA's Monday decision was hailed by the American Bird Conservancy as marking a huge victory for wildlife and the environment. The action involves a pesticide sold under the name Furadan by the FMC Corp. The EPA said the toxic insecticide does not meet current U.S. food safety standards. The EPA said its ruling will eliminate residues of carbofuran in food,...

A U.S.-led study suggests insecticides that would kill just older mosquitoes would be a better way of controlling malaria. Pennsylvania State University Professor Andrew Read said such an approach would be a more sustainable way of controlling the disease and might lead to evolution-proof insecticides that never become obsolete. Each year malaria kills about a million people, but many of the chemicals used to kill the insects become ineffective, the scientists said, since repeated exposure to...

Killing just the older mosquitoes would be a more sustainable way of controlling malaria, according to entomologists who add that the approach may lead to evolution-proof insecticides that never become obsolete.Each year malaria -- spread through mosquito bites -- kills about a million people, but many of the chemicals used to kill the insects become ineffective. Repeated exposure to an insecticide breeds a new generation of mosquitoes that are resistant to that particular...

Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
