Bacteria exposed to antibiotics for long periods find ways to resist the drugs — by quickly pumping them out of their cells, for example, or modifying the compounds so they're no longer toxic.

Antidepressants are the most widely used treatment for people with moderate to severe depression but up to two thirds of people with depression don't respond fully to antidepressants.

A new paper in The Lancet says cognitive behavioral therapy reduces symptoms of depression and helps improve patient quality of life when provided in addition to the usual care.

They say this is the first large-scale trial to test the effectiveness of cognitive behavioral therapy, a type of talking psychotherapy, given in addition to usual care that includes antidepressants. The CoBalT study aimed to determine the best 'next step' treatment for people whose depression had not responded to medication alone. 

In modern times, we have been spoiled by the ability of the private sector to make technology shrink in both cost and size - but Moore's Law can't do that forever using regular electrical signals.

Maybe it is time for Moore's Light to take over? 

Whether or not different species of early humans interbred and produced offspring of mixed ancestry - hybridization - has been the subject of recent studies but the findings are not universally accepted.

Electronic cigarettes are booming. Germans love to smoke, but love dying not so much, and so an estimated two million people in Germany have already turned to the vapor cigarette, which many view as a healthy alternative to conventional smoking.

Some are warning of possible health risks, claiming that the long-term consequences cannot yet be foreseen, the old 'you cannot prove it it safe' impossibility, and studies to-date have been mixed.

Partof the issue is that smoking remains a hot-button issue, and so there is a general lack of substantiated facts. Researchers at the Fraunhofer Institute for Wood Research WKI in Braunschweig say they can be objective and set out to learn if e-cigarettes pollute the surrounding air. Second hand vapor, anyone?

If you looked at the "Black Marble" images of Earth at night released by NASA and the National Oceanic and Atmospheric Administration this week, you may have noticed bright areas in the largely uninhabited western part of Australia.

What's the story?
