For more than 60 years, fusion scientists have tried to use "magnetic bottles" of various shapes and sizes to confine extremely hot plasmas, with the goal of producing practical fusion energy. But turbulence in the plasma has, so far, confounded researchers' ability to efficiently contain the intense heat within the core of the fusion device, reducing performance. Now, scientists have used one of the world's largest supercomputers to reveal the complex interplay between two types of turbulence known to occur in fusion plasmas, paving the way for improved fusion reactor design.

Placebo-controlled trials are the recognized standard for demonstrating the efficacy of clinical and pharmacological treatments so it is significant to proponents of mindfulness meditation that it reduced pain more effectively than placebo.

The paper Journal of Neuroscience says that study participants who practiced mindfulness meditation reported greater pain relief than placebo. The study used a two-pronged approach - pain ratings and brain imaging - to determine whether mindfulness meditation is merely a placebo effect. Seventy-five healthy, pain-free participants were randomly assigned to one of four groups: mindfulness meditation, placebo meditation ("sham" meditation), placebo analgesic cream (petroleum jelly) or control.

You know our eyelids blink but less know is that so does the human brain, dropping a few frames of visual information here and there.

Those lapses of attention come fast -- maybe just once every tenth of a second. But some people may be missing more than others, according to psychologists at the University of Wisconsin-Madison.

"Intuitively we have this sense that we're viewing the world in a continuous stream, constantly taking in the same amount of information," says Jason Samaha, a University of Wisconsin-Madison doctoral student in psychology. "So if I told people that every 100 milliseconds their brains were taking a bit of a break, I think that would surprise a lot of them."

Gymnastic feats like balance beam routines clearly require a great deal of coordination. But even seemingly trivial actions such as crossing stepping-stones on a river or just walking in a straight line require these very same skills. The group of Dr. Megan Carey, principal investigator at Champalimaud Centre for the Unknown, has developed a novel tool to investigate how the brain generates coordinated movement.

A recent paper explores the evolution of disease classification practices and the progress made since William Cullen's seminal Nosolagae Methodicae synopsis published in 1769. The paper discusses some of the additions to the ICD-10 including some of the less obvious conditions like obesity that may set the precedent for classifying aging as a disease.

The long, shallow grooves lining the surface of Phobos are likely early signs of the structural failure that will ultimately destroy this moon of Mars.

Orbiting a mere 3,700 miles (6,000 kilometers) above the surface of Mars, Phobos is closer to its planet than any other moon in the solar system. Mars' gravity is drawing in Phobos, the larger of its two moons, by about 6.6 feet (2 meters) every hundred years. Scientists expect the moon to be pulled apart in 30 to 50 million years.

"We think that Phobos has already started to fail, and the first sign of this failure is the production of these grooves," said Terry Hurford of NASA's Goddard Space Flight Center in Greenbelt, Maryland.

A team of physicists led by Stephen Jardin of the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has discovered a mechanism that prevents the electrical current flowing through fusion plasma from repeatedly peaking and crashing. This behavior is known as a "sawtooth cycle" and can cause instabilities within the plasma's core. The results have been accepted for publication in Physical Review Letters. The research was supported by the DOE Office of Science (Office of Fusion Energy Sciences).

Childhood cancer survivors are at heightened risk of a wide range of autoimmune diseases, reveals research published online in the Annals of the Rheumatic Diseases.

Diabetes and Addison's disease--a condition in which the adrenal gland doesn't work properly--make up almost half of the excess cases, the findings show.

Over the past 40 years, the number of childhood cancer survivors has risen sharply, resulting in a five year survival rate of 80% among children who succumb to the disease.

But mounting evidence suggests that these survivors are at heightened risk of various health problems as adults, which increase in number and severity as they get older.

Intensive farming practices such as larger herd size, maize growth, fewer hedgerows and the use of silage have been linked to higher risk of bovine TB, new research has concluded.

A study by the University of Exeter, funded by BBSRC and published in the Royal Society journal Biological Letters, analysed data from 503 farms which have suffered a TB breakdown alongside 808 control farms in areas of high TB risk.
