Use of Insecticides Linked to Lasting Neurological Problems for Farmers

...ides used by the licensed farmers over the past 25 years are no longer available commercially. DDT, a well known example of an organochlorine, has been banned for use in the US since 1972. Organophosphates, such as malathion, chlorypyrifos, and diazinon, have been banned or restricted for home and garden u...

LUCA technologies confirms real-time methane generation

Variation in women's X chromosomes may explain differences among individuals, between sexes

Originally, scientists had assumed that the inactivation process resulted in complete silencing of the genes on...

Gene Signatures Predict Interferon Response For Multiple Sclerosis Patients

These analyses identified genes that increased activity independently of clinical response (interferon can activate genes that have no effect on disease), as well as genes that w...

"Your endothelial cells---the cells that line all of your blood vessels---generate nitric oxide. The nitric oxide prod...

Advances in the characterisation of the oyster mushroom genes
