Seeing things: A new transparent display system could provide heads-up data Posted: 21 Jan 2014 08:34 AM PST Scientists have developed a new approach to produce transparent projection screens. Their result paves the way for a new class of transparent displays with many attractive features, including wide viewing angle, scalability to large size, and low cost.

Energy-dense sugar battery created Posted: 21 Jan 2014 06:30 AM PST A new sugar battery that could be on the market and powering the world's gadgets in three years has an energy density and order of magnitude higher than others.

Toddlers' aggression strongly associated with genetic factors Posted: 20 Jan 2014 04:24 PM PST A new study provides greater understanding of how to address childhood aggression, and suggests that it is strongly associated with genetic factors in the child.

Daily rhythms of our genes are disrupted when sleep times shift Posted: 20 Jan 2014 02:33 PM PST A new study found that the daily rhythms of our genes are disrupted when sleep times shift.

Rosetta: 'Sleeping beauty' wakes up from deep space hibernation Posted: 20 Jan 2014 08:11 AM PST It was a fairy-tale ending to a tense chapter in the story of the Rosetta space mission this evening as the European Space Agency heard from its distant spacecraft for the first time in 31 months.

Ingredients in chocolate, tea, berries could guard against diabetes Posted: 20 Jan 2014 06:06 AM PST Eating high levels of flavonoids including anthocyanins and other compounds (found in berries, tea, and chocolate) could offer protection from type 2 diabetes -- according to research. The study of almost 2,000 people showed that high intakes of these dietary compounds are associated with lower insulin resistance and better blood glucose regulation.

Study reveals how ecstasy acts on brain, hints at therapeutic uses Posted: 17 Jan 2014 07:39 AM PST Brain imaging experiments have revealed for the first time how ecstasy produces feelings of euphoria in users. The findings hint at ways that ecstasy, or MDMA, might be useful in the treatment of anxiety and post-traumatic stress disorder (PTSD).

Vitamin D supplements reduce pain in fibromyalgia sufferers Posted: 17 Jan 2014 06:05 AM PST Researchers say vitamin D may be cost-effective treatment or adjunct for patients with fibromyalgia syndrome and low vitamin D levels.

Large landmasses existed 2.7 billion years ago Posted: 15 Jan 2014 04:54 AM PST Some 71 percent of Earth's surface is covered by oceans and 29 percent by land. The question of when large landmasses emerged from the oceans has always been hotly debated. New investigations by geoscientists have shown that large land masses did indeed exist on Earth 2.7 billion years ago.

Scientists discover new pathway for artificial photosynthesis Posted: 14 Jan 2014 05:31 PM PST Currently, the most efficient methods that we have of making fuel -- principally hydrogen -- from sunlight and water involve rare and expensive metal catalysts, like platinum. In a new study, researchers have found a new, more efficient way to link a less expensive synthetic cobalt-containing catalyst to an organic light-sensitive molecule, called a chromophore.

Where does all Earth's gold come from? Precious metals the result of meteorite bombardment, rock analysis finds Posted: 07 Sep 2011 10:20 AM PDT Ultra high precision analyses of some of the oldest rock samples on Earth provides clear evidence that the planet's accessible reserves of precious metals are the result of a bombardment of meteorites more than 200 million years after Earth was formed.
