Mathematical model shows how brain remains stable during learning

Posted: 22 Oct 2014 09:30 AM PDT

Complex biochemical signals that coordinate fast and slow changes in neuronal networks keep the brain in balance during learning, according to an international team of scientists. Neuronal networks form a learning machine that allows the brain to extract and store new information from its surroundings via the senses. Researchers have long puzzled over how the brain achieves sensitivity and stability to unexpected new experiences during learning -- two seemingly contradictory requirements.

An effective, cost-saving way to detect natural gas pipeline leaks

Posted: 22 Oct 2014 07:35 AM PDT

Major leaks from oil and gas pipelines have led to home evacuations, explosions, millions of dollars in lawsuit payouts and valuable natural resources escaping into the air, ground and water. Scientists say they have now developed a new software-based method that finds leaks even when they're small, which could help prevent serious incidents -- and save money for customers and industry.

A 'Star Wars' laser bullet -- this is what it really looks like

Posted: 22 Oct 2014 07:35 AM PDT

Action-packed science-fiction movies often feature colourful laser bolts. But what would a real laser missile look like during flight, if we could only make it out? How would it illuminate its surroundings?

Skin patch could replace the syringe for disease diagnosis

Posted: 22 Oct 2014 07:35 AM PDT

Drawing blood and testing it is standard practice for many medical diagnostics. As a less painful alternative, scientists are developing skin patches that could one day replace the syringe. Scientists now they have designed and successfully tested, for the first time, a small skin patch that detected malaria proteins in live mice. It could someday be adapted for use in humans to diagnose other diseases, too.

Association between air toxics, childhood autism

Posted: 22 Oct 2014 07:35 AM PDT

Children with autism spectrum disorder were more likely to have been exposed to higher levels of certain air toxics during their mothers' pregnancies and the first two years of life compared to children without the condition, according to the preliminary findings of an investigation of American children.

New devices based on metamaterials

Posted: 22 Oct 2014 07:33 AM PDT

Researchers have designed and manufactured new devices based on metamaterials (artificial materials with properties not found in nature). They achieved the first experimental demonstration ever with epsilon-near-zero metamaterials. "These materials have surprising characteristics, such as the fact that a wave traveling within them can do so at almost infinite speed and, thus, can be transmitted from one place to another without hardly any loss of energy, no matter how unusual or complicated the shape of the material," according to a researcher.

New window on the early Universe

Posted: 22 Oct 2014 05:43 AM PDT

Scientists see good times approaching for astrophysicists after hatching a new observational strategy to distill detailed information from  galaxies at the edge of the Universe. Using two world-class supercomputers, the researchers were able to demonstrate the effectiveness of their approach by simulating the formation of a massive galaxy at the dawn of cosmic time. The ALMA radio telescope – which stands at an elevation of 5,000 meters in the Atacama Desert of Chile, one of the driest places on earth – was then used to forge observations of the galaxy, showing how their method improves upon previous efforts.

Susceptibility for relapsing major depressive disorder can be calculated

Posted: 22 Oct 2014 05:43 AM PDT
