Curvy mountain belts Posted: 29 Jun 2012 06:19 PM PDT Mountain belts on Earth are most commonly formed by collision of one or more tectonic plates. The process of collision, uplift, and subsequent erosion of long mountain belts often produces profound global effects, including changes in regional and global climates, as well as the formation of important economic resources, including oil and gas reservoirs and ore deposits. Understanding the formation of mountain belts is thus a very important element of earth science research.

Easter Island drug raises cognition throughout life span in mice Posted: 29 Jun 2012 06:19 PM PDT Rapamycin, a compound first isolated from soil on Easter Island, enhanced learning and memory in a study of young, middle-aged and older mice. The findings are from the School of Medicine and Barshop Institute at The University of Texas Health Science Center San Antonio.

New fuel cell keeps going after the hydrogen runs out Posted: 29 Jun 2012 06:19 PM PDT Materials scientists have demonstrated a solid-oxide fuel cell that converts hydrogen into electricity but can also store electrochemical energy like a battery. This fuel cell can continue to produce power for a short time after its fuel has run out.

Scientists urge new approaches to plant research Posted: 29 Jun 2012 06:18 PM PDT If humans are to survive as a species, we must turn more to plants for any number of valuable lessons, experts say.

New gene mutations that lead to enlarged brain size, cancer, autism, epilepsy identified Posted: 29 Jun 2012 06:18 PM PDT Scientist have discovered new gene mutations associated with markedly enlarged brain size, or megalencephaly.

Bees shed light on human sweet perception and metabolic disorders Posted: 29 Jun 2012 06:18 PM PDT Scientists have discovered that honey bees may teach us about basic connections between taste perception and metabolic disorders in humans. By experimenting with honey bee genetics, researchers have identified connections between sugar sensitivity, diabetic physiology and carbohydrate metabolism. Bees and humans may partially share these connections.

Clothing the body electric: Cotton T-shirt fabric can store electricity, maybe keep your cell phone charged Posted: 29 Jun 2012 06:15 PM PDT The fabric in a cotton T-shirt was converted into a material that can store electricity. A flexible source of electrical power made from this kind of material might one day be able to charge your cell phone, or any number of other mobile electronic devices.

Making the shortest light bursts leads to better understanding of nature Posted: 29 Jun 2012 06:15 PM PDT An attosecond is a ridiculously brief sliver of time – a scant billionth of a billionth of a second. This may seem too short to have any practical applications, but at the atomic level, where electrons zip and jump about, these vanishingly short timescales are crucial to a deeper understanding of science.

New properties of stem cells via simulated microgravity Posted: 29 Jun 2012 06:14 PM PDT A recent study set out to illustrate novel mechanical transduction properties of hematopoietic stem cells in relation to defining the expression of humoral factors by facilitating paracrine/autocrine signalling via microgravity.

Stealthy microscopy method visualizes E. coli sub-cellular structure in 3-D Posted: 29 Jun 2012 11:26 AM PDT A sub-cellular world has been opened up for scientists to study E. coli and other tissues in new ways, thanks to a microscopy method that stealthily provides 3-D, high-quality images of the internal structure of cells without disturbing the specimen.

Scientists help create an extra second of summer: Leap second to be added on July 1, 2012 Posted: 29 Jun 2012 11:26 AM PDT Scientists will be adding a leap second at 00:59 BST on July 1 to its atomic clocks, to ensure UK time remains synchronized with international time.

'Ambient' bullying gives employees urge to quit Posted: 29 Jun 2012 11:25 AM PDT Merely showing up to work in an environment where bullying goes on is enough to make many of us think about quitting, a new study suggests.

Welsh reindeer is Britain's oldest rock art, U-series dating suggests Posted: 29 Jun 2012 11:25 AM PDT A reindeer engraved on the wall of a cave in South Wales has been found to date from at least 14,505 years ago -- making it the oldest known rock art in the British Isles.

Caffeine boosts power for elderly muscles Posted: 29 Jun 2012 09:04 AM PDT Caffeine boosts power in older muscles, suggesting the stimulant could aid elderly people to maintain their strength, reducing the incidence of falls and injuries, according to new research.

How to bend it like Beckham: Physics students calculate perfect soccer ball kicking formula Posted: 29 Jun 2012 09:03 AM PDT Now that David Beckham won't be appearing at the London 2012 Olympics, other members of Team GB wanting to brush up on their free-kicks can rest easy. A physics students has figured out the optimum way of kicking a soccer ball in order to make it bend into the goal. The ex-England captain's curling free-kicks became legendary, and even inspired the title of the 2002 film Bend It Like Beckham.

Multiple mergers generate ultraluminous infrared galaxy Posted: 29 Jun 2012 09:03 AM PDT Ultraluminous infrared galaxies are the most luminous class of galaxies in the relatively near or local Universe. Most of their energy output is in the infrared range, suggesting that they contain a large amount of dust, an indication of immense star formation.

Colorful light at the end of the tunnel for radiation detection Posted: 29 Jun 2012 08:56 AM PDT Nanomaterials researchers have developed a new technique for radiation detection that could make radiation detection in cargo and baggage more effective and less costly for homeland security inspectors.

First heralded single photon source made from silicon Posted: 28 Jun 2012 11:57 AM PDT In an important step towards more practical quantum information processing, researchers have built the first heralded single photon source made from silicon. This source complements two other recently developed silicon-based technologies needed to build a quantum optical circuit or a secure quantum communication system.
