Running cockroaches start to recover from being shoved sideways before their dawdling nervous system kicks in to tell their legs what to do, researchers have found. These new insights on how biological systems stabilize could one day help engineers design steadier robots and improve doctors' understanding of human gait...

By analyzing data from DNA microarrays, a UNC-led team has completed a study that confirms the presence of four molecular classes of the disease and extends previous results by suggesting that there may be an underlying connection between the molecular classes and observed genomic events, some of which affect known cancer...

For years researchers have been searching for a way to treat diabetics by reactivating their insulin-producing beta cells, with limited success. The "reprogramming" of related alpha cells into beta cells may one day offer a novel and complementary approach for treating Type 2 diabetes. Treating human and mouse cells with...

Geology articles posted online ahead of print on Feb. 20, 2013, include several modeling and simulation studies as well as studies on the Exmouth Sub-basin, Australia; the West Kunlun Range, northern Tibetan Plateau; Krakenes Lake, Norway; the Azores islands; and the hot springs of Colorado.

Washington University engineering researchers have created a new type of air-cleaning technology that could better protect human lungs from allergens, airborne viruses and ultrafine particles in the air. The device, known as the SXC ESP, was created by a team led by Pratim Biswas, Ph.D., the Lucy & Stanley Lopata Professor...

A protein known for turning on genes to help cells survive low-oxygen conditions also slows down the copying of new DNA strands, thus shutting down the growth of new cells, Johns Hopkins researchers report. Their discovery has wide-ranging implications, they say, given the importance of this copying -- known as DNA...

Flowers' methods of communicating are at least as sophisticated as any devised by an advertising agency, according to a new study. The research shows for the first time that pollinators such as bumblebees are able to find and distinguish electric signals given out by flowers. However, for any advertisement to be successful, it...

Researchers propose a new technique that might one day reveal in higher detail than ever before the composition and characteristics of the deep Earth. There's just one catch: it relies on a fifth force of nature that has not yet been detected, but which some particle physicists think might exist. If it does, this new force...

Evidence from Siberian caves suggests that a global temperature rise of 1.5 degrees Celsius could see permanently frozen ground thaw over a large area of Siberia, threatening release of carbon from soils, and damage to natural and human environments. Fuente :...

Preliminary research findings suggest learning to use Facebook may help give adults older than 65 a cognitive boost. The study shows that seniors who learned to use Facebook saw improvements in their ability to continuously monitor and quickly add or delete the contents of their working memory....

Solar geoengineering is a proposed approach to reduce the effects of climate change due to greenhouse gasses by deflecting some of the sun's incoming radiation. This type of proposed solution carries with it a number of uncertainties, however, including geopolitical questions about who would be in...

Researchers have developed a robotic bat wing that is providing valuable new information about dynamics of flapping flight in real bats. From an engineering perspective, the researchers hope the data may make for better aircraft, especially micro air vehicles. From a biological and evolutionary...

Researchers have developed a way to melt or "weld" specific portions of polymers by embedding aligned nanoparticles within the materials. Their technique, which melts fibers along a chosen direction within a material, may lead to stronger, more resilient nanofibers and materials. Fuente :...

Scientists have found compelling evidence that older adults can eliminate forgetfulness and perform as well as younger adults on memory tests. The cognitive boost comes from a surprising source -- a distraction learning strategy. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/4...

Black holes shape the growth and death of the stars around them through their powerful gravitational pull and explosive ejections of energy. In a recent article, researchers predicted the formation of accretion disks and relativistic jets that warp and bend more than previously thought, shaped by the extreme gravity of the...

The sounds uttered by birds offer in several respects the nearest analogy to language," Charles Darwin wrote in "The Descent of Man" (1871), while contemplating how humans learned to speak. Language, he speculated, might have had its origins in singing, which "might have given rise to words expressive of various complex...

Each fall millions of monarch butterflies migrate south in order to escape frigid temperatures, traveling up to 2,000 miles to an overwintering site in a specific grove of fir trees in central Mexico. A new study suggests that exposure to coldness found in the microenvironment of the monarch's overwintering site triggers their...

There is research that is off the wall, some off the charts and some off the planet, such as what a Texas A&M University aerospace and physics professor is exploring. It’s a plan to deflect a killer asteroid by using paint, and the science behind it is absolutely rock solid, so to speak, so much so that NASA is getting...
