| Our hands evolved for punching, not just dexterity Posted: 19 Dec 2012 07:31 PM PST Men whacked punching bags for a new study that suggests human hands evolved not only for the manual dexterity needed to use tools, play a violin or paint a work of art, but so men could make fists and fight.  |
| Multi-tasking whales sing while feeding, not just breeding Posted: 19 Dec 2012 02:41 PM PST Humpback whales are famed for their songs, most often heard in breeding season when males are competing to mate with females. In recent years, however, reports of whale songs occurring outside traditional breeding grounds have become more common. A new study may help explain why.  |
| Lizard tails detach at a biological 'dotted line' Posted: 19 Dec 2012 02:39 PM PST Like sheets of paper marked with perforated lines, gecko tails have unique structural marks that help them sever their tails to make a quick getaway. Though voluntarily shedding a body part in this manner is a well-known phenomenon, research reveals aspects of the process that may have applications for structural engineers making similar, quickly detachable structures.  |
| Pocket test measures fifty things in a drop of blood Posted: 19 Dec 2012 12:26 PM PST A new device about the size of a business card could allow health care providers to test for insulin and other blood proteins, cholesterol, and even signs of viral or bacterial infection all at the same time —- with one drop of blood.  |
| Are bacteria making you hungry? Posted: 19 Dec 2012 11:23 AM PST Over the last half decade, it has become increasingly clear that the normal gastrointestinal (GI) bacteria play a variety of very important roles in the biology of human and animals. Now researchers propose yet another role for GI bacteria: that they exert some control over their hosts' appetites.  |
| When the ice melts, the Earth spews fire Posted: 19 Dec 2012 10:35 AM PST It has long been known that volcanic activity can cause short-term variations in climate. Now, researchers have found evidence that the reverse process also occurs: Climate affects volcanic activity.  |
| For power and status, dominance and skill trump likability Posted: 19 Dec 2012 05:42 AM PST Finding the next Barack Obama or Warren Buffett might be as simple as looking at who attracts the most eyes in a crowd, a new study finds. For the study, which used eye-tracking technology, participants who observed groups of strangers were able to accurately predict who would emerge as leader of the group in 120 seconds or less.  |
| Paper waste used to make bricks Posted: 19 Dec 2012 05:40 AM PST Researchers have mixed waste from the paper industry with ceramic material used in the construction industry. The result is a brick that has low thermal conductivity meaning it acts as a good insulator. However, its mechanical resistance still requires improvement.  |
