Pollutants, Disease And Biological Weapons Detected By Tiny "Lab-On-A-Chip"

For centuries, animals have been our first line of defense against toxins. A canary in a coalmine served as a living monitor for poisonous gases. Scientists used fish to test for contaminants in our water. Even with modern advances, though, it can take days to detect a fatal chemical or organism. Until now. Working in the miniaturized world of nanotechnology, Tel Aviv University researchers have made an enormous - and humane - leap forward in the detection of pollutants. Read more ...

Does Gene Show Link Between Migraine And Stroke Or Heart Attacks?

Does Gene Show Link Between Migraine And Stroke Or Heart Attacks?
New research looks at whether a gene variant may affect the link between migraine and stroke or heart attacks. The study is published in the February 17, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology. The study involved 25,000 women who answered a questionnaire about their history of migraines and migraines with aura. Aura is usually described as visual disturbances, such as flashing lights or geometric patterns.
