Secrets of 'Magic' Antidepressant by Yale Team

Submitted by Anonymous Coward
An anonymous reader writes "Yale researchers have discovered how a novel anti-depressant can take effect in hours, rather than the weeks or months usually required for most drugs currently on the market. The findings, described in the August 20 issue of the journal Science, should speed development of a safe and easy-to-administer form of the anti-depressant ketamine, which has already proven remarkably effective in treating severely depressed patients. The Yale scientists found that, in rats, ketamine not only quickly improves depression-like behaviors but actually restores connections between brain cells damaged by chronic stress."

grrlscientist writes "Laurie Santos is trying to find the roots of human irrationality by watching the way our primates make decisions. This video documents a clever series of experiments in 'monkeynomics' and shows that some of the stupid decisions we make are made by our primate relatives too."

Gisg writes "The University of Arizona team reported that their genetically modified mosquitoes are immune to the malaria-causing parasite, a single-cell organism called Plasmodium. Riehle and his colleagues tested their genetically-altered mosquitoes by feeding them malaria-infested blood. Not even one mosquito became infected with the malaria parasite."

Increasing Algal Blooms Threaten China's Coasts

eldavojohn writes "While the United States deals with oil on its southern shores, China faces hundreds of square kilometers of algal blooms headed toward its shores. One large 200 sq km blob is about 13 kilometers (eight miles) away from Jiaonan in Shandong province. In 2008, China employed 10,000 people to clean a similar algal bloom in order to keep its nearby shore pristine for the Olympics. China has had several case studies (PDF) done of its algal blooms, which many attribute to nutrient pollution in lakes and shores. An Alaskan blob also amounted to an algal bloom, while West Coast red tide algal blooms are making wild shellfish deadly to consume."
