Researchers have devised a nanoscale sensor to electronically read the sequence of a single DNA molecule, a technique that is fast and inexpensive and could make DNA sequencing widely available.
The technique could lead to affordable personalized medicine, potentially revealing predispositions for afflictions such as cancer, diabetes or addiction. (more…)
Alcoholism is a tough addiction to kick. Eventually, most people return to drinking. But some Dutch and German psychological scientists have tested a short-term regime that promises to help alcoholics stay sober.

To boost treatment success, his team developed cognitive-bias modification, or CBM, which, for the first time, “tries to turn around those impulsive responses.” (more…)
