Multi-disciplinary Penn research identifies protein required for cell movement - 12/08/2013

A new multi-disciplinary study by University of Pennsylvania researchers has now illuminated a crucial step in the process of cell movement. The protein they examined, Exo70, induces a reshaping of the cell's plasma membrane, a necessary step in how a cell migrates from one location to another....

Researchers find 'grammar' plays key role in activating genes - 12/08/2013

Researchers have probed deep into the cell's genome, beyond the basic genetic code, to begin learning the "grammar" that helps determine whether or not a gene gets switched on to make the protein it encodes. Fuente : http://www.eurekalert.org/pub_releases/2013-08/uoc...

Seasonal carbon dioxide range expanding as more is added to Earth's atmosphere - 12/08/2013

Levels of carbon dioxide in the atmosphere rise and fall each year as plants, through photosynthesis and respiration, take up the gas in spring and summer, and release it in fall and winter. Fuente : http://www.eurekalert.org/pub_releases/2013-08/nsf...

Brain's flexible hub network helps humans adapt - 12/08/2013

New research from Washington University in St. Louis offers compelling evidence that a well-connected core brain network based in the lateral prefrontal cortex and the posterior parietal cortex -- parts of the brain most changed evolutionarily since our common ancestor with chimpanzees -- contains...

New gene repair technique promises advances in regenerative medicine - 12/08/2013

Using human pluripotent stem cells and DNA-cutting protein from meningitis bacteria, researchers from the Morgridge Institute for Research and Northwestern University have created an efficient way to target and repair defective genes. Fuente : http://www.eurekalert.org/pub_releases/2013-08/uow...

Research on which gender pays for dates shows change and resistance from convention - 12/08/2013

Conventional notions of chivalry dictate that on a "date," the man pays, whereas egalitarian ideals suggest gender should not determine who pays for the entertainment expenses. This research examines the extent to which people embrace or reject these competing notions after nearly 50 years of...

African-American females have good odds to get a loan - 12/08/2013

Lenders have high impressions of African-American females and are apt to loan them as much money as white males, according to a new study by University of Iowa sociologist Sarah Harkness. Conversely, loan applications from African-American males and white females are judged more strictly....

'Fifty Shades of Grey' perpetuates violence against women - 12/08/2013

"Fifty Shades of Grey," the best-selling novel that's promoted as a tale of erotic romance, actually perpetuates the problem of violence against women, a new study finds. Fuente : http://www.eurekalert.org/pub_releases/2013-08/msu...

Study finds better-performing elementary students receive disproportionate attention from parents - 12/08/2013

New study redefines how plaques grow in heart disease - 11/08/2013

The growth of deadly plaque inside the walls of arteries may not happen as scientists believed, researchers have found. New research also suggests a new potential target in the treatment of atherosclerosis, a leading cause of cardiovascular disease and death globally. Fuente :...

Magnetization controlled at picosecond intervals - 11/08/2013

A terahertz laser makes it possible to control a material's magnetization at a timescale of picoseconds (0.000,000,000,001 seconds). In their experiment, the researchers shone extremely short light pulses from the laser onto a magnetic material, where the magnetic moments - "elementary magnets" -...

Greenland ice is melting -- even from below: Heat flow from the mantle contributes to the ice melt - 11/08/2013

The Greenland ice sheet is melting from below, caused by a high heat flow from the mantle into the lithosphere. This influence is very variable spatially and has its origin in an exceptionally thin lithosphere. Consequently, there is an increased heat flow from the mantle and a complex interplay...

Device captures signatures and fingerprints with tiny LEDs - 11/08/2013

Researchers want to put your signature up in lights. Using thousands of nanometer-scale wires, the researchers have developed a sensor device that converts mechanical pressure – from a signature or a fingerprint – directly into light signals that can be captured and processed optically.
