|  Formation of unusual ring of radiation around Earth explained  | 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. | Read More » Calming fear during sleep  | 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. | Read More » Protein identified that regulates cellular trafficking, potential for anti-cancer therapy  | 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. | Read More » Scientists closer to universal flu vaccine after pandemic 'natural experiment'  | 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. | Read More » A boost for cellular profiling  | 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. | Read More » Is this my finger?
