Chelyabinsk meteorite's rocky past: Research points to previous collision or near miss in space Posted: 26 Aug 2013 06:56 PM PDT Where did the Chelyabinsk meteorite come from? As a meteoroid, it either collided with another body in the solar system or came too close to the Sun before it fell to Earth, according to new research.

Scientists shut down reproductive ability, desire in pest insects Posted: 26 Aug 2013 03:29 PM PDT Entomologists have identified a neuropeptide named natalisin that regulates the sexual activity and reproductive ability of insects. The finding may open new possibilities for environmentally friendly pest management.

Language can reveal the invisible, study shows Posted: 26 Aug 2013 03:05 PM PDT It is natural to imagine that the sense of sight takes in the world as it is -- simply passing on what the eyes collect from light reflected by the objects around us. But the eyes do not work alone. What we see is a function not only of incoming visual information, but also how that information is interpreted in light of other visual experiences, and may even be influenced by language.

Immune system, skin microbiome 'complement' one another Posted: 26 Aug 2013 03:05 PM PDT Researchers demonstrate for the first time that the immune system influences the skin microbiome. A new study found that the skin microbiome -- a collection of microorganisms inhabiting the human body -- is governed, at least in part, by an ancient branch of the immune system called complement.

Why do haters have to hate? Newly identified personality trait holds clues Posted: 26 Aug 2013 09:31 AM PDT New research has uncovered the reason why some people seem to dislike everything while others seem to like everything. Apparently, it's all part of our individual personality -- a dimension that researchers have coined "dispositional attitude."

Climate change: Ocean acidification amplifies global warming Posted: 26 Aug 2013 06:58 AM PDT Scientists have demonstrated that ocean acidification may amplify global warming through the biogenic production of the marine sulfur component dimethylsulphide (DMS). Ocean acidification has the potential to speed up global warming considerably, according to new research.
