| Emotion reversed in left-handers' brains Posted: 02 May 2012 03:48 PM PDT The way we use our hands may determine how emotions are organized in our brains, according to a recent study. Motivation, the drive to approach or withdraw from physical and social stimuli, is a basic building block of human emotion. |
| Zombie-ant fungus is under attack, research reveals Posted: 02 May 2012 03:47 PM PDT A parasite that fights the zombie-ant fungus has yielded some of its secrets to an international research team. The research reveals, for the first time, how an entire ant colony is able to survive infestations by the zombie-ant fungus, which invades an ant's brain and causes it to march to its death at a mass grave near the ant colony, where the fungus spores erupt out of the ant's head. |
| Genes may explain why some people turn their noses up at pork Posted: 02 May 2012 03:46 PM PDT If you don't like the taste of pork, the reason may be that your genes cause you to smell the meat more intensely, according to a new study. |
| Iceman mummy: 5,000-year-old red blood cells discovered -- oldest blood known to modern science Posted: 02 May 2012 11:11 AM PDT His DNA has been decoded; samples from his stomach and intestines have allowed us to reconstruct his very last meal. The circumstances of his violent death appear to have been explained. However, what had, at least thus far, eluded the scientists, was identifying any traces of blood in Ötzi, the 5,000-year-old glacier mummy. Examination of his aorta had yielded no results. Yet recently, a team of scientists from Italy and Germany, using nanotechnology, succeeded in locating red blood cells in Ötzi's wounds, thereby discovering the oldest traces of blood to have been found anywhere in the world. |
| Mining for heat: Abandoned mine tunnels might ferry geothermal energy from deep underground Posted: 02 May 2012 08:29 AM PDT Abandoned mine tunnels might ferry geothermal energy from deep underground to help heat homes and offices. |
| Electronic nanotube nose out in front Posted: 02 May 2012 08:29 AM PDT A new nanotube super sensor is able to detect subtle differences with a single sniff. For example, the chemical dimethylsulfone is associated with skin cancer. The human nose cannot detect this volatile but it could be detected with the new sensor at concentrations as low as 25 parts per billion. |
| Artificial muscle: Squid and zebrafish cells inspire camouflaging smart materials Posted: 02 May 2012 06:19 AM PDT Researchers have created artificial muscles that can be transformed at the flick of a switch to mimic the remarkable camouflaging abilities of organisms such as squid and zebrafish. They demonstrated two individual transforming mechanisms that they believe could be used in 'smart clothing' to trigger camouflaging tricks similar to those seen in nature. |
| Vibrating suit gives Olympic hopefuls competitive advantage Posted: 02 May 2012 06:19 AM PDT Pioneering research has applications in both health and sports. The suit is designed to give wearers feedback about where their body is in space. It does this by focusing on key points in the body, taking relative measurements between them to check the user's position. This data, much more simple to acquire and treat in real time than more complex motion capture systems, is then used to give the wearer feedback in real time about their movement. |
| Dental fillings that kill bacteria and re-mineralize the tooth Posted: 01 May 2012 03:28 PM PDT Scientists using nanotechology have created the first cavity-filling composite that kills harmful bacteria and regenerates tooth structure lost to bacterial decay. This first-of-a-kind nanocomposite will be tested in animal teeth then human volunteers next. |
