UCLA life scientists have identified six "words" that specific immune cells use to call up immune defense genes — an important step toward understanding the language the body uses to marshal responses to threats. In addition, they discovered that the incorrect use of two of these words can activate the wrong genes, resulting in the autoimmune disease know...

The advance, researchers say, is like the cellular equivalent of discovering the Rosetta stone and may eventually lead to new treatments for diseases.

Temperature Explains Why Aquatic Life More Diverse Near Equator Details Share This The bulging, equator-belted midsection of Earth currently teems with a greater diversity of life than anywhere else — a biodiversity that generally wanes when moving from the tropics to the mid-latitudes and the mid-latitudes to the poles. The bulging, equator-belted midsection of Earth currently teems with a greater diversity of life than anywhere else — a biodiversity that genera...

VIDEO: This video is footage from an experimental trial, where the bonnetheads swimming behavior is affected by the magnetic field it is experiencing. view more  Credit: Bryan Keller Sea turtles are known for relying on magnetic signatures to find their way across thousands of miles to the very beaches where they hatched. Now, researchers reporting in the journal Current Biology on May 6 have some of the first solid evidence that sharks also rely on magnetic fields for ...

 E-Mail The decision to donate to a charity is often driven by emotion rather than by calculated assessments based on how to make the biggest impact. In a review article published on April 29 in the journal Trends in Cognitive Sciences, researchers look at what they call "the psychology of (in)effective altruism" and how people can be encouraged to direct their charitable contributions in ways that allow them to get more bang for the buck--and help them to have a larger influence. "In the pas...

VIDEO: This video shows the flexible TEG wristband converts heat emitted by skin into electric power and light up an LED. view more  Credit: Yijie Liu Scientists in China have developed a small, flexible device that can convert heat emitted from human skin to electrical power. In their research, presented April 29 in the journal Cell Reports Physical Science, the team showed that the device could power an LED light in real time when worn on a wristband. The findings sug...

Scale bar, 20 mm. view more  Credit: Calvin Ly Psychedelic drugs have shown promise for treating neuropsychiatric disorders such as depression and posttraumatic stress disorder. However, due to their hallucinatory side effects, some researchers are trying to identify drugs that could offer the benefits of psychedelics without causing hallucinati...
