| NASA Curiosity rover detects no methane on Mars Posted: 22 Sep 2013 07:28 PM PDT Data from NASA's Curiosity rover has revealed the Martian environment lacks methane. This is a surprise to researchers because previous data indicated positive detections.  |
| Posted: 22 Sep 2013 05:59 PM PDT People can be easily tricked into believing an artificial finger is their own, shows a new study. The results reveal that the brain does not require multiple signals to build a picture body ownership, as this is the first time the illusion has been created using sensory inputs from the muscle alone.  |
| Creating electricity with caged atoms Posted: 22 Sep 2013 12:51 PM PDT Clathrates are crystals consisting of tiny cages in which single atoms can be enclosed. These atoms significantly alter the material properties of the crystal. By trapping cerium atoms in a clathrate, scientists have created a material which has extremely strong thermoelectric properties. It can be used to turn waste heat into electricity.  |
| Protein identified that regulates cellular trafficking, potential for anti-cancer therapy Posted: 22 Sep 2013 12:51 PM PDT Scientists have identified a new regulator for the intracellular trafficking of proteins between the endoplasmic reticulum and Golgi apparatus, which is a crucial process for maintaining homeostasis and prevention of human disease. The study provides a new avenue to investigate anti-cancer agents that target the regulatory protein UVRAG and/or intracellular trafficking process.  |
| Formation of unusual ring of radiation around Earth explained Posted: 22 Sep 2013 12:51 PM PDT Since the discovery of the Van Allen radiation belts, scientists believed these belts consisted of two rings of highly charged particles. In February, scientists reported the discovery of a previously unknown third radiation ring -- a narrow ring that briefly circled the Earth for a month. Space scientists have successfully modeled and explained the unprecedented behavior of this third ring, and show that its energetic particles are driven by very different physics than the others.  |
| Posted: 22 Sep 2013 12:51 PM PDT A fear memory was reduced in people by exposing them to the memory over and over again while they slept. It's the first time that emotional memory has been manipulated during sleep, report scientists. The finding potentially offers a new way to enhance the typical daytime treatment of phobias through exposure therapy by adding a nighttime component. A common treatment for phobias is gradual exposure to the feared object until the fear is extinguished.  |
| Scientists closer to universal flu vaccine after pandemic 'natural experiment' Posted: 22 Sep 2013 12:50 PM PDT Scientists have moved closer to developing a universal flu vaccine after using the 2009 pandemic as a natural experiment to study why some people seem to resist severe illness.  |
| Propofol discovery may aid development of new anesthetics Posted: 22 Sep 2013 12:49 PM PDT Researchers for the first time have identified the site where the widely used anesthetic drug propofol binds to receptors in the brain to sedate patients during surgery.  |
| A boost for cellular profiling Posted: 22 Sep 2013 12:49 PM PDT A team of researchers report a dramatically improved technique for analyzing the genes expressed within a single cell — a capability of relevance to everything from basic research to future cancer diagnostics.  |
