One planet, two stars: New research shows how circumbinary planets form Posted: 31 Jan 2014 10:07 AM PST Luke Skywalker's home planet Tatooine would have formed far from its current location in the Star Wars universe, a new study into its real world counterparts, observed by the Kepler space telescope, suggests.

Teaching young wolves new tricks: Wolves are considerably better imitators than dogs Posted: 31 Jan 2014 05:34 AM PST Although wolves and dogs are closely related, they show some striking differences. Scientists have undertaken experiments that suggest that wolves observe one another more closely than dogs and so are better at learning from one another. The scientists believe that cooperation among wolves is the basis of the understanding between dogs and humans.

Worry on the brain: Researchers find new area linked to anxiety Posted: 30 Jan 2014 11:13 AM PST Previous studies of anxiety in the brain have focused on the amygdala, but a team of researchers had a hunch that understanding a different brain area, the lateral septum (LS), could provide more clues into how the brain processes anxiety. Their instincts paid off -- the team has found a neural circuit that connects the LS with other brain structures in a manner that directly influences anxiety.

Cell cycle speed is key to making aging cells young again Posted: 30 Jan 2014 09:16 AM PST Researchers identified a major obstacle to converting cells back to their youthful state -- the speed of the cell cycle, or the time required for a cell to divide. When the cell cycle accelerates to a certain speed, the barriers that keep a cell's fate on one path diminish. In such a state, cells are easily persuaded to change their identity and become pluripotent, or capable of becoming multiple cell types.

Mysterious ocean circles off the Baltic coast explained Posted: 30 Jan 2014 07:20 AM PST Are they bomb craters from World War II? Are they landing marks for aliens? Since the first images of the mysterious ocean circles off the Baltic coast of Denmark were taken in 2008, people have tried to find an explanation. Now researchers finally present a scientific explanation.

Sea level variations escalating along eastern Gulf of Mexico coast Posted: 29 Jan 2014 01:55 PM PST Around the globe, sea levels typically rise a little in summer and fall again in winter. Now, a new study shows that, from the Florida Keys to southern Alabama, those fluctuations have been intensifying over the past 20 years.

'Rogue' asteroids may be the norm Posted: 29 Jan 2014 10:51 AM PST A new map developed by astronomers charts the size, composition, and location of more than 100,000 asteroids throughout the solar system, and shows that rogue asteroids are actually more common than previously thought. Particularly in the solar system's main asteroid belt -- between Mars and Jupiter -- the researchers found a compositionally diverse mix of asteroids.

First weather map of brown dwarf: Surface of nearest brown dwarf charted Posted: 29 Jan 2014 10:49 AM PST The European Southern Observatory's Very Large Telescope has been used to create the first ever map of the weather on the surface of the nearest brown dwarf to Earth. An international team has made a chart of the dark and light features on WISE J104915.57-531906.1B, which is informally known as Luhman 16B and is one of two recently discovered brown dwarfs forming a pair only six light-years from the Sun.

Caffeine use disorder: Widespread health problem that needs more attention Posted: 28 Jan 2014 12:40 PM PST "I'm a zombie without my morning coffee." "My blood type is Diet Coke." "Caffeine isn't a drug, it's a vitamin." Most people make jokes like these about needing a daily boost from their favorite caffeinated beverage -- whether first thing in the morning or to prevent the after-lunch slump. But a recent study indicates that more people are dependent on caffeine to the point that they suffer withdrawal symptoms and are unable to reduce caffeine consumption even if they have another condition that may be impacted by caffeine -- such as a pregnancy, a heart condition, or a bleeding disorder.
