Softer fast food restaurant lighting and music can cut calorie intake 18 percent Posted: 28 Aug 2012 04:49 PM PDT Your mood for food can be changed by a restaurant's choice of music and lighting, leading to increased satisfaction and reduced calorie intake, according to a new study.

Small family size increases wealth of descendants but reduces evolutionary success Posted: 28 Aug 2012 04:09 PM PDT Evolutionary biologists have long puzzled over this because natural selection is expected to have selected for organisms that try to maximize their reproduction. But in industrialized societies around the world, increasing wealth coincides with people deliberately limiting their family size -- the so-called 'demographic transition'. In a new study, researchers reject a popular theory put forward to explain the phenomenon. This 'adaptive' hypothesis proposes that low fertility may boost evolutionary success in the long term by increasing offspring wealth, which in turn eventually increases the number of long-term descendants because richer offspring end up having more children.

Less is more for reef-building corals: Surprisingly more flexible corals are more sensitive to environment disturbances Posted: 28 Aug 2012 04:09 PM PDT Researchers have made a discovery that challenges a major theory in the field of coral reef ecology. The general assumption has been that the more flexible corals are, regarding which species of single-celled algae they host in coral tissues, the greater ability corals will have to survive environmental stress. However, scientists documented that the more flexible corals are, the more sensitive to environment disturbances they are.

Chimpanzees create 'social traditions': Unique handclasp grooming behavior reveals local difference Posted: 28 Aug 2012 04:08 PM PDT Researchers have revealed that chimpanzees are not only capable of learning from one another, but also use this social information to form and maintain local traditions. A recent study shows that the way in which chimpanzees groom each other depends on the community to which they belong. Specifically, it is the unique handclasp grooming behaviour that reveals this local difference.

Curiosity rover plays first song transmitted from another planet Posted: 28 Aug 2012 04:06 PM PDT For the first time in history, a recorded song has been beamed back to Earth from another planet. Students, special guests and news media gathered at NASA's Jet Propulsion Laboratory in Pasadena, Calif., today to hear "Reach for the Stars" by musician will.i.am after it was transmitted from the surface of Mars by the Curiosity rover.

NASA's Kepler discovers multiple planets orbiting a pair of stars Posted: 28 Aug 2012 04:01 PM PDT Coming less than a year after the announcement of the first circumbinary planet, Kepler-16b, NASA's Kepler mission has discovered multiple transiting planets orbiting two suns for the first time.

Male snails babysit for other dads: Family secrets of marine whelk Solenosteira macrospira Posted: 28 Aug 2012 01:30 PM PDT Pity the male of the marine whelk, Solenosteira macrospira. He does all the work of raising the young, from egg-laying to hatching -- even though few of the baby snails are his own. Throw in extensive promiscuity and sibling cannibalism, and the species has one of the most extreme life histories in the animal kingdom.

Magnetic vortex reveals key to spintronic speed limit Posted: 28 Aug 2012 01:30 PM PDT Spintronics use electron spin to write and read information. To mobilize this emerging technology, scientists must understand exactly how to manipulate spin as a carrier of computer code. Now, scientists have precisely measured a key parameter of electron interactions called non-adiabatic spin torque that is essential to the development of spintronic devices. This unprecedented precision guides the reading and writing of digital information and sets the spintronic speed limit.

Metabolism in the brain fluctuates with circadian rhythm Posted: 28 Aug 2012 11:33 AM PDT The rhythm of life is driven by the cycles of day and night, and most organisms carry in their cells a common, (roughly) 24-hour beat. In animals, this rhythm emerges from the suprachiasmatic nucleus in the hypothalamus. Take it out of the brain and keep it alive in a lab dish and this "brain clock" will keep on ticking for days. A new study reveals that the brain clock itself is driven, in part, by metabolism.

Heightened visual awareness by following brains natural rhythms? Posted: 28 Aug 2012 10:51 AM PDT Like a melody that keeps playing in your head even after the music stops, researchers have shown that the beat goes on when it comes to the human visual system. Researchers used periodic visual stimuli and electroencephalogram recordings and found, one, that they could precisely time the brain's natural oscillations to future repetitions of the event, and, two, that the effect occurred even after the prompting stimuli was discontinued. These rhythmic oscillations lead to a heightened visual awareness of the next event, meaning controlling them could lead to better visual processing when it matters most, such as in environments like air traffic control towers.
