New digital map reveals stunning hidden archaeology of Stonehenge Posted: 09 Sep 2014 04:21 PM PDT A host of previously unknown archaeological monuments have been discovered around Stonehenge as part of an unprecedented digital mapping project that will transform our knowledge of this iconic landscape -- including remarkable new findings on the world's largest 'super henge,' Durrington Walls.

'Solid' light could compute previously unsolvable problems Posted: 09 Sep 2014 10:08 AM PDT Researchers have begun crystallizing light as part of an effort to answer fundamental questions about the physics of matter. As part of an effort to develop exotic materials such as room-temperature superconductors, the researchers have locked together photons, the basic element of light, so that they become fixed in place.

First evidence for water ice clouds found outside our solar system Posted: 09 Sep 2014 08:07 AM PDT A team of scientists has discovered the first evidence of water ice clouds on an object outside of our own Solar System. Water ice clouds exist on our own gas giant planets -- Jupiter, Saturn, Uranus, and Neptune -- but have not been seen outside of the planets orbiting our Sun until now.

Intervention in 6-month-olds with autism eliminates symptoms, developmental delay Posted: 09 Sep 2014 06:37 AM PDT Treatment at the earliest age when autism spectrum disorder is detectable -- in infants as young as 6 months old -- significantly reduces symptoms so that by age 3 most who received the therapy had neither autism nor delay, a research study has found.

Interactive dark matter could explain Milky Way's missing satellite galaxies Posted: 08 Sep 2014 05:46 PM PDT Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected. Computer simulations of the formation of our galaxy suggest that there should be many more small galaxies around the Milky Way than are observed through telescopes. This has thrown doubt on the generally accepted theory of cold dark matter, an invisible and mysterious substance that scientists predict should allow for more galaxy formation around the Milky Way than is seen. Now cosmologists think they have found a potential solution to the problem.

In one of nature's innovations, a single cell smashes and rebuilds its own genome Posted: 08 Sep 2014 12:29 PM PDT A pond-dwelling, single-celled organism has the remarkable ability to break its own DNA into nearly a quarter-million pieces and rapidly reassemble those pieces when it's time to mate. This elaborate process could provide a template for understanding how chromosomes in more complex animals such as humans break apart and reassemble, as can happen during the onset of cancer.

Study traces ecological collapse over 6,000 years of Egyptian history Posted: 08 Sep 2014 12:29 PM PDT Depictions of animals in ancient Egyptian artifacts have helped scientists assemble a detailed record of the large mammals that lived in the Nile Valley over the past 6,000 years. A new analysis of this record shows that species extinctions, probably caused by a drying climate and growing human population in the region, have made the ecosystem progressively less stable.

There could be increased numbers of psychopaths in senior managerial positions, high levels of business, research shows Posted: 08 Sep 2014 09:07 AM PDT For the first time, it has been demonstrated that people with psychopathic tendencies who have high IQs can mask their symptoms by manipulating tests designed to reveal their personalities. It raises the possibility that large numbers of ruthless risk-takers are able to conceal their level of psychopathy as they rise to key managerial posts.

Taking short walking breaks found to reverse negative effects of prolonged sitting Posted: 08 Sep 2014 05:37 AM PDT Three easy -- one could even say slow -- 5-minute walks can reverse harm caused to leg arteries during three hours of prolonged sitting, researchers report. Sitting for long periods of time is associated with risk factors such as higher cholesterol levels and greater waist circumference that can lead to cardiovascular and metabolic disease. When people sit, slack muscles do not contract to effectively pump blood to the heart. Blood can pool in the legs and affect the endothelial function of arteries, or the ability of blood vessels to expand from increased blood flow.
