One planet, two stars: New research shows how circumbinary planets form Posted: 31 Jan 2014 10:07 AM PST Luke Skywalker's home planet Tatooine would have formed far from its current location in the Star Wars universe, a new study into its real world counterparts, observed by the Kepler space telescope, suggests.

Smart Notices could take us beyond copyright Posted: 31 Jan 2014 10:07 AM PST Dynamic Smart Notices could replace standard licencing agreements for software, online services and digital goods, according to a researchers.

Making color: When two red photons make a blue photon Posted: 31 Jan 2014 10:05 AM PST Can scientists generate any color of light? The answer is not really, but the invention of the laser in 1960 opened new doors for this endeavor. Scientists have now demonstrated a new semiconductor microstructure that performs frequency conversion. This design is a factor of 1000 smaller than previous devices.

How neurons control fine motor behavior of the arm Posted: 31 Jan 2014 07:12 AM PST Motor commands issued by the brain to activate arm muscles take two different routes. As a research group has now discovered, many neurons in the spinal cord send their instructions not only towards the musculature, but at the same time also back to the brain via an exquisitely organized network.

Success in targeted therapy for common form of lung cancer, study shows Posted: 31 Jan 2014 06:35 AM PST Researchers have found that a combination of two already-in-use drugs may have an effect on stopping the growth of the most common genetic subtype of lung cancer setting the stage for clinical trials.

Nine steps to save waterways and fisheries identified by researchers Posted: 31 Jan 2014 06:35 AM PST The key to clean waterways and sustainable fisheries is to follow nine guiding principles of water management, says a team of Canadian biologists.

Lemur lovers sync their scents: Strength of a lemur couple's bond is reflected in the similarity of their scents Posted: 31 Jan 2014 05:35 AM PST Mating pairs of lemurs mirror each other's scent-marking behavior and even start to smell alike after they have reproduced. Matched scents are possibly a way to combine territory defenses or to advertise their relationship status to the rest of their group, according to researchers. Couples who haven't had kids yet spend the most time scent-marking and investigating each other's odors.

Vibrations influence circadian clock of fruit fly Posted: 31 Jan 2014 05:35 AM PST The internal circadian clock of a Drosophila (fruit fly) can be synchronized using vibrations, according to new research. The results of the study suggest that an animal's own movements can influence its clock.

Gastric bypass improves insulin secretion in pigs Posted: 31 Jan 2014 05:34 AM PST The majority of gastric bypass patients mysteriously recover from their type 2 diabetes within days, before any weight loss has taken place. A study has now shown that the insulin-producing beta cells increase in number and performance after the surgery.

Teaching young wolves new tricks: Wolves are considerably better imitators than dogs Posted: 31 Jan 2014 05:34 AM PST Although wolves and dogs are closely related, they show some striking differences. Scientists have undertaken experiments that suggest that wolves observe one another more closely than dogs and so are better at learning from one another. The scientists believe that cooperation among wolves is the basis of the understanding between dogs and humans.

New catalyst to convert greenhouse gases into chemicals Posted: 31 Jan 2014 05:32 AM PST Researchers have developed a highly selective catalyst capable of electrochemically converting carbon dioxide -- a greenhouse gas -- to carbon monoxide with 92 percent efficiency. The carbon monoxide then can be used to develop useful chemicals.

Diagnosis just a breath away with new laser that advances breath analysis for disease diagnosis Posted: 31 Jan 2014 05:32 AM PST Physics researchers have developed a new type of laser that will enable exciting new advances in areas as diverse as breath analysis for disease diagnosis and remote sensing of critical greenhouse gases.

NSA pursues quantum technology Posted: 30 Jan 2014 06:08 PM PST Researchers explain how the revelation that the US National Security Agency is developing quantum computers has renewed interest and sparked debate on just how far ahead they are of the world's major labs looking to develop the same technology.

Imaging technique shows brain anatomy change in women with MS, depression Posted: 30 Jan 2014 06:07 PM PST A multicenter research team used a new, automated technique to identify shrinkage of a mood-regulating brain structure in a large sample of women with MS who also have a certain type of depression.

Detailed look at HIV in action: Researchers gain a better understanding of the virus through electron microscopy Posted: 30 Jan 2014 04:04 PM PST Researchers reporting today are the first to have utilized high-resolution electron microscopy to look at HIV infection within the actual tissue of an infected organism, providing perhaps the most detailed characterization yet of HIV infection in the gut.

Childhood depression may increase risk of heart disease by teen years Posted: 30 Jan 2014 01:44 PM PST Children with depression are more likely to be obese, smoke and be inactive, and can show the effects of heart disease as early as their teen years, according to a newly published.

Researcher turns sights on prostate cancer, tissue engineering, blood vessel repair Posted: 30 Jan 2014 01:43 PM PST When biology and materials science converge, the results can be new materials that can be used to deliver targeted drugs, repair damaged arteries or rebuild failing tissues, such as the anterior cruciate ligament, the ACL injury that can end sports careers. One bioengineer is developing polymers designed to target all three.

Revealing how the brain recognizes speech sounds Posted: 30 Jan 2014 11:13 AM PST Researchers are reporting a detailed account of how speech sounds are identified by the human brain. The finding, they said, may add to our understanding of language disorders, including dyslexia.

Storage system for 'big data' dramatically speeds access to information Posted: 30 Jan 2014 08:10 AM PST As computers enter ever more areas of our daily lives, the amount of data they produce has grown enormously. But for this "big data" to be useful it must first be analyzed, meaning it needs to be stored in such a way that it can be accessed quickly when required.
