Ultracold disappearing act: 'Matter waves' move through one another but never share space Posted: 02 Nov 2014 01:01 PM PST How can two clumps of matter pass through each other without sharing space? Physicists have documented a strange disappearing act by colliding Bose Einstein condensates that appear to keep their distance even as they pass through one another.

Possible alternative to antibiotics Posted: 02 Nov 2014 01:00 PM PST A novel substance for the treatment of severe bacterial infections has been developed to work without antibiotics. Scientists say that this would prevent the development of antibiotic resistance.

Massive geographic change may have triggered explosion of animal life Posted: 01 Nov 2014 02:32 PM PDT A new analysis of geologic history may help solve the riddle of the "Cambrian explosion," the rapid diversification of animal life in the fossil record 530 million years ago that has puzzled scientists since the time of Charles Darwin. New research suggests a major tectonic event may be connected with the apparent burst of life that occurred 530 million years ago during the Cambrian explosion.

Fun and games make for better learners Posted: 31 Oct 2014 12:00 PM PDT Four minutes of physical activity can improve behavior in the classroom for primary school students, according to new research. A brief, high-intensity interval exercise, or a 'FUNterval,' for Grade 2 and Grade 4 students reduced off-task behaviors like fidgeting or inattentiveness in the classroom.

High prevalence of vitamin D deficiency across the board in neuromuscular disease Posted: 31 Oct 2014 05:19 AM PDT More credence has been added to a growing awareness of the high prevalence of vitamin D deficiency in neuromuscular disease by newly presented research. Vitamin D supplementation has been suggested to improve function in frail elderly patients at risk for falls, as well as individuals with myasthenia gravis and Parkinson's. The impact of vitamin D deficiency and supplementation on function in other neurologic conditions has yet to be explored.

They know the drill: Leading the league in boring through ice sheets Posted: 30 Oct 2014 01:30 PM PDT Hollow coring drills are used to extract ice cores that can analyze the past atmosphere. Scientists have now documented carbon dioxide in the atmosphere between 23,000 and 9,000 years ago, based on data from an 11,000-foot hole in Antarctica.

Emerging disease could wipe out American, European salamanders Posted: 30 Oct 2014 11:22 AM PDT A fungal disease from Asia wiped out salamanders in parts of Europe and will likely reach the US through the international wildlife trade in Asian newts sold as pets, say US experts. Scientists report the fungus arose in Asia 30 million years ago and is lethal to many European and American newt species. It has not yet been found in North American wild amphibians.

Toddlers copy their peers to fit in, but apes don't Posted: 30 Oct 2014 10:33 AM PDT From the playground to the board room, people often follow, or conform, to the behavior of those around them as a way of fitting in. New research shows that this behavioral conformity appears early in human children, but isn't evidenced by apes like chimpanzees and orangutans.

Could copper prevent spread of Ebola? Posted: 30 Oct 2014 07:12 AM PDT Copper could help to prevent the spread of Ebola, researchers have found. While hand washing, disinfectants and quarantine procedures alone have been found to be insufficient to contain the spread of the virus, research has offered promising evidence that antimicrobial copper - engineering materials with intrinsic hygiene benefits - could be a valuable addition to these existing measures.

The science of charismatic voices: How one man was viewed as authoritarian, then benevolent Posted: 29 Oct 2014 05:39 PM PDT When a right-wing Italian politician named Umberto Bossi suffered a severe stroke in 2004, his speech became permanently impaired. Strangely, this change impacted Bossi's perception among his party's followers -- from appearing authoritarian to benevolent. Now researchers think they know why.

Clean smell doesn't always mean clean air Posted: 29 Oct 2014 11:12 AM PDT Scientists are taking a closer look at aerosol formation involving an organic compound -- called limonene -- that provides the pleasant smell of cleaning products and air fresheners. This research will help to determine what byproducts these sweet-smelling compounds are adding to the air while we are using them to remove germs and odors.

In autoimmune diseases affecting millions, researchers pinpoint genetic risks, cellular culprits Posted: 29 Oct 2014 11:12 AM PDT Scores of autoimmune diseases afflicting one in 12 Americans -- ranging from type 1 diabetes, to multiple sclerosis (MS), to rheumatoid arthritis, to asthma -- mysteriously cause the immune system to harm tissues within our own bodies. Now, a new study pinpoints the complex genetic origins for many of these diseases, a discovery that may lead to better diagnosis and ultimately to improved treatments.

How culture influences violence among the Amazon's ‘fierce people' Posted: 27 Oct 2014 03:19 PM PDT When Yanomamö men in the Amazon raided villages and killed decades ago, they formed alliances with men in other villages rather than just with close kin like chimpanzees do. And the spoils of war came from marrying their allies' sisters and daughters, rather than taking their victims' land and women.

Resveratrol may be natural exercise performance enhancer Posted: 19 Jun 2012 07:59 PM PDT A natural compound found in some fruits, nuts and red wine may enhance exercise training and performance, demonstrates newly published medical research.
