Your memory is no video camera: It edits the past with present experiences Posted: 04 Feb 2014 03:56 PM PST Your memory is a wily time traveler, plucking fragments of the present and inserting them into the past, reports a new study. In terms of accuracy, it's no video camera. Rather, memory rewrites the past with current information, updating your recollections with new experiences to aid survival. Love at first sight, for example, is more likely a trick of your memory than a Hollywood-worthy moment.

Kepler finds a very wobbly planet: Rapid and erratic changes in seasons Posted: 04 Feb 2014 10:39 AM PST Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. That is the situation on a weird, wobbly world found by NASA's planet-hunting Kepler space telescope.

First evidence of common brain code for space, time, distance Posted: 04 Feb 2014 09:37 AM PST A new study provides the first evidence that people use the same brain circuitry to figure out space, time and social distances. The results may help to determine whether we care enough to act: Is something happening here, now, to someone I love? Or over there, years from now, to a stranger?

Blue light may fight fatigue around the clock Posted: 03 Feb 2014 04:18 PM PST Researchers have found that exposure to short wavelength, or blue light, during the biological day directly and immediately improves alertness and performance.

Dramatic thinning of Arctic lake ice cuts winter ice season by 24 days compared to 1950 Posted: 03 Feb 2014 09:28 AM PST Arctic lakes have been freezing up later in the year and thawing earlier, creating a winter ice season about 24 days shorter than it was in 1950, a new study has found.

Researchers develop first single-molecule LED Posted: 03 Feb 2014 06:35 AM PST The ultimate challenge in the race to miniaturize light emitting diodes (LED) has now been met: Scientists have developed the first ever single-molecule LED. The device is formed from a single polythiophene wire placed between the tip of a scanning tunneling microscope and a gold surface. It emits light only when the current passes in a certain direction.

Rat islands 'a laboratory of future evolution': Rats predicted to fill in Earth's emptying ecospace Posted: 03 Feb 2014 05:40 AM PST New research predicts that rats will continue to grow and fill a 'significant chunk' of Earth's emptying ecospace. Their global influence is likely to grow in the future as larger mammals continue to become extinct.

Drug trafficking leads to deforestation in Central America Posted: 30 Jan 2014 11:12 AM PST Add yet another threat to the list of problems facing the rapidly disappearing rainforests of Central America: drug trafficking. In a new study, researchers who have done work in Central America point to growing evidence that drug trafficking threatens forests in remote areas of Honduras, Guatemala, Nicaragua and nearby countries.

Poor breakfast in youth linked to metabolic syndrome in adulthood Posted: 29 Jan 2014 04:58 AM PST It is often said that breakfast is important for our health, and a new study supports this claim. The study revealed that adolescents who ate poor breakfasts displayed a higher incidence of metabolic syndrome 27 years later, compared with those who ate more substantial breakfasts.

Social scientists build case for 'survival of the kindest' Posted: 08 Dec 2009 12:53 PM PST Researchers are challenging long-held beliefs that human beings are wired to be selfish. In a wide range of studies, social scientists are amassing a growing body of evidence to show we are evolving to become more compassionate and collaborative in our quest to survive and thrive.
