An embryonic cell's fate is sealed by the speed of a signal

August 5, 2014 2:56 pm | by EurekAlert! | Comments

When embryonic cells get the signal to specialize the call can come quickly. Or it can arrive slowly. Now, new research from Rockefeller University suggests the speed at which a cell in an embryo receives that signal has an unexpected influence on that cell's fate....

Scientists uncover combustion mechanism to better predict warming by wildfires

August 5, 2014 2:52 pm | by EurekAlert! | Comments

Scientists have uncovered key attributes of so-called "brown carbon" from wildfires, airborne atmospheric particles that may have influenced current climate models that failed to take the material's warming effects into account. The work was described by a collaborative team of researchers....

New idea for hearing improvement in patients with hearing aids under background noise

August 5, 2014 2:49 pm | by EurekAlert! | Comments

Patients with implanted artificial cochlea often complain that they cannot recognize speech well in natural environments, especially if background of noise is present. Researchers think that a poor ability to localize sound in a complex auditory environment is responsible for the weak speech perception....

When highest perceptual ability occurs in a day?

August 5, 2014 2:41 pm | by EurekAlert! | Comments

Many previous chronobiological studies have reported on detection of circadian fluctuation in performing simple motor tasks, fine skilled movement, and anaerobic exercise. However, to the best of our knowledge, literature concerning variation of sensory function ...

Surprise discovery could see graphene used to improve health

August 5, 2014 1:48 pm | by EurekAlert! | Comments

A chance discovery about the 'wonder material' graphene – already exciting scientists because of its potential uses in electronics, energy storage and energy generation – takes it a step closer to being used in medicine and human health. Researchers from Monash University ...

LEDs made from 'wonder material' perovskite

August 5, 2014 1:46 pm | by EurekAlert! | Comments

A hybrid form of perovskite - the same type of material which has recently been found to make highly efficient solar cells that could one day replace silicon - has been used to make low-cost, easily manufactured LEDs, potentially opening up a wide range of commercial applications....

Carnegie Mellon photo editing tool enables object images to be manipulated in 3-D

August 5, 2014 1:43 pm | by EurekAlert! | Comments

Editors of photos routinely resize objects, or move them up, down or sideways, but Carnegie Mellon University researchers are adding an extra dimension to photo editing by enabling editors to turn or flip objects any way they want, even exposing surfaces not visible in the original photograph....

Diamond defect interior design

August 5, 2014 1:36 pm | by EurekAlert! | Comments

By carefully controlling the position of an atomic-scale diamond defect within a volume smaller than what some viruses would fill, researchers have cleared a path toward better quantum computers and nanoscale sensors. They describe their technique in a paper published in the journal....

A group of scientists from South Korea have converted used-cigarette butts into a high-performing material that could be integrated into computers, handheld devices, electrical vehicles and wind turbines to store energy. Presenting their findings today ...

A Closer Look: Secure your phone without passcodes

August 5, 2014 1:28 pm | by ANICK JESDANUN, AP Technology Writer | Comments

Passcodes are outdated. They're a pain to use, and they aren't secure when they are based on easy-to-guess digits, such as a birth date or street address. Many people don't bother using them on phones, even though that means any thief can get instant access....

More than six decades in Everitt Lab

August 5, 2014 12:18 pm | by University of Illinois | Comments

Outside an unassuming room in Everitt Laboratory, which most recently served as the business office, there’s a small plaque, set in a wood frame. “In this room,” the inscription reads, “during the spring semester of 1952, John Bardeen—the two-time Nobel laureate ...

History of culture visualized through art history, physics, complexity

August 4, 2014 4:51 pm | by EurekAlert! | Comments

Quantifying and transforming the history of culture into visual representation isn't easy. There are thousands of individual stories, across thousands of years, to consider, and some historical conditions are nearly impossible to measure. Addressing this challenge, Dr. Maximilian Schich ...
