Insignia -- A new way to identify viruses and bacteria
...d to rapidly compute signatures for any particular target
species. The program can have a wide range of applications, from diagnosing infections in humans to detecting harmful microbes in a water supply. To maximize its use by scientists in a variety of disciplines, Insignia is freely available on the autho...
Combining NSAIDs with chemotherapy, radiation may improve cancer treatment
...f cells in S phase suggests this class of drug may target
the radio-resistant cells, and use of the drug together with radiation might provide better tumor control than radiation alone. Because inflammation is thought to play a role in the development of certain cancers, numerous studies have investigated...
Newly identified mechanism for silencing genes points to possible anti-cancer strategies

New study examines 'brain's own marijuana'
...nxiety. An alternative strategy may be to directly target
the brains own marijuana. The success of such a strategy requires a better understanding of how endocannabinoid moderates stress-related behaviors and how stress and stress hormones activate the endocannabinoid system. Haj-Dahmane and his co-investi...
