New Field-deployable Biosensor Detects Avian Influenza Virus In Minutes
10/2/07
Quick identification of avian influenza infection in poultry is critical to controlling outbreaks, but current detection methods can require several days to produce results. A new biosensor can detect avian influenza in just minutes. In addition to being a rapid test, the biosensor is economical, field-deployable, sensitive to different viral strains and requires no labels or reagents.

Mechanism Behind Nicotine Dependency Revealed
Many more people try to quit smoking than succeed in giving up this nicotine-delivering habit. Now, a group of scientists has identified one neurobiological mechanism that contributes to nicotine dependence, and to the anxiety and craving experienced upon withdrawal. The findings also suggest a new approach to developing drugs that could help smokers quit.
