Psychologists document the age our earliest memories fade Posted: 24 Jan 2014 10:57 AM PST Although infants use their memories to learn new information, few adults can remember events in their lives that happened prior to the age of three. Psychologists have now documented that age seven is when these earliest memories tend to fade into oblivion, a phenomenon known as "childhood amnesia." The study is the first empirical demonstration of the onset of childhood amnesia, and involved interviewing children about past events in their lives.

Mars could have supported life: Ten years on Mars leads to livable mud Posted: 24 Jan 2014 06:37 AM PST Some of the oldest minerals ever analyzed by NASA's Mars Opportunity Rover show that around four billion years ago Mars had liquid water so fresh it could have supported life.

Rainforests in Far East shaped by humans for the last 11,000 years Posted: 24 Jan 2014 05:26 AM PST New research shows that the tropical forests of South East Asia have been shaped by humans for the last 11,000 years. The rain forests of Borneo, Sumatra, Java, Thailand and Vietnam were previously thought to have been largely unaffected by humans, but the latest research suggests otherwise.

A thousand years ago, Central Europeans digested milk as well as us today Posted: 23 Jan 2014 07:19 PM PST Back in the Middle Ages, Central Europeans were already capable of digesting milk, yogurt and cheese just as well as most people of European descent are today. Researchers have discovered that the population of the medieval town of Dalheim had a similar genetic predisposition for milk digestion to present-day Germans and Austrians. Moreover, the study reveals that lactose tolerance was more widespread than previously believed.

Changing climate: How dust changed the face of Earth Posted: 23 Jan 2014 11:20 AM PST In spring 2010, the research icebreaker Polarstern returned from the South Pacific with a scientific treasure -- ocean sediments from a previously almost unexplored part of the South Polar Sea. What looks like an inconspicuous sample of mud to a layman is, to geological history researchers, a valuable archive from which they can reconstruct the climatic history of the polar areas over many years of analysis. This, in turn, is of fundamental importance for understanding global climatic development.

Los Angeles would experience stronger-than-expected ground motion in major earthquake, virtual earthquake generator shows Posted: 23 Jan 2014 11:19 AM PST Scientists have developed a new "virtual earthquake" technique and used it to confirm a prediction that Los Angeles would experience stronger-than-expected ground motion if a major quake occurred along the southern San Andreas Fault.

Fur and feathers keep animals warm by scattering light Posted: 23 Jan 2014 09:58 AM PST In work that has major implications for improving the performance of building insulation, scientists have calculated that hairs that reflect infrared light may contribute significant insulating power to the exceptionally warm winter coats of polar bears and other animals.

Study: Electric drive vehicles have little impact on US pollutant emissions Posted: 21 Jan 2014 11:38 AM PST A new study indicates that even a sharp increase in the use of electric drive passenger vehicles by 2050 would not significantly reduce emissions of high-profile air pollutants carbon dioxide, sulfur dioxide or nitrogen oxides.

Training the brain using neurofeedback Posted: 21 Jan 2014 08:34 AM PST A new brain-imaging technique enables people to "watch" their own brain activity in real time and to control or adjust function in predetermined brain regions. The study is the first to demonstrate that magnetoencephalography can be used as a potential therapeutic tool to control and train specific targeted brain regions. This advanced brain-imaging technology has important clinical applications for numerous neurological and neuropsychiatric conditions.

Blue-eyed Humans Have A Single, Common Ancestor Posted: 30 Jan 2008 02:03 PM PST New research shows that people with blue eyes have a single, common ancestor. Scientists have tracked down a genetic mutation which took place 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today.
