The researchers measured dopamine transporter levels in 20 adult ADHD subjects who had never received medication, never abused drugs (except nicotine), and had no past or present history of mental or neurological di...

Cougar predation key to ecosystem health

...o mount, land managers may have to acknowledge the potentially enormous impact of these grazing animals on other ecosystem processes, scientists say. This could open the way to new management options once the role of herbivory by deer, elk, or other grazing animals is more fully understood. In sys...

Results with newer bladeless LASIK equivalent to standard microkeratome LASIK

...ed to compare risks," he says. "Bladeless LASIK is potentially safer because of its computer-controlled precision, the ability to visualize the flap being created, and to stop the procedure whenever necessary. That said, however, the risk of complications with a traditional, microkeratome blade is very small: so...

Tests may help answer questions about GMOs and allergies

...e best known case of a genetically engineered crop potentially causing allergies was StarLink corn. Created by Aventis in 1996, StarLink contained the cry9C protein from a common soil bacterium, a strain of Bacillus thuringiensis. The cry9C protein protected the corn from several types of corn borers and black c...

Liquorice cancer care
