Single gene controls jet lag

August 14, 2014 2:25 pm | by EurekAlert! | Comments

LA JOLLA–Scientists at the Salk Institute for Biological Studies have identified a gene that regulates sleep and wake rhythms. The discovery of the role of this gene, called Lhx1, provides scientists with a potential therapeutic target to help night-shift workers....

New material could enhance fast and accurate DNA sequencing

August 14, 2014 2:20 pm | by EurekAlert! | Comments

Gene-based personalized medicine has many possibilities for diagnosis and targeted therapy, but one big bottleneck: the expensive and time-consuming DNA-sequencing process. Now, researchers at the University of Illinois at Urbana-Champaign ...

Patent examiners more likely to approve marginal inventions when pressed for time

August 14, 2014 2:16 pm | by EurekAlert! | Comments

Haste makes waste, as the old saying goes. And according to research from a University of Illinois expert in patent law, the same adage could be applied to the U.S. Patent and Trademark Office, where high-ranking examiners have a tendency to rubber-stamp patents of questionable merit....


Monitoring meteor showers from space

August 14, 2014 2:12 pm | by EurekAlert! | Comments

Those who enjoy the spectacle of the Perseids, Geminids or other annual meteor showers likely aren't thinking about where these shooting stars originated or whether they might pose a danger. Scientists, however, think about such things and will use the vantage point....


NERSC launches next-generation code optimization effort

August 14, 2014 2:03 pm | by EurekAlert! | Comments

With the promise of exascale supercomputers looming on the horizon, much of the roadmap is dotted with questions about hardware design and how to make these systems energy efficient enough so that centers can afford to run them. Often taking a back seat ...

Novel chip-based platform could simplify measurements of single molecules

August 14, 2014 2:01 pm | by EurekAlert! | Comments

Researchers at UC Santa Cruz have developed a new approach for studying single molecules and nanoparticles by combining electrical and optical measurements on an integrated chip-based platform. In a paper published July 9 in Nano Letters, the researchers reported using the device....

Virginia Tech unmanned aircraft test site 'fully operational,' FAA says

The Mid-Atlantic Aviation Partnership's Unmanned Aircraft Systems test site program is fully operational and ready to conduct research vital to integrate unmanned aircraft into the nation's airspace, Federal Aviation Administration officials announced Wednesday....


People fake to look authentic on social media

August 14, 2014 1:48 pm | by EurekAlert! | Comments

Presenting an authentic image on social network sites (SNSs) includes an element of fakery according to a new study by researchers at Aalto University. During the study, researchers discovered that being authentic is very important for social media users....


Genetic signal prevents immune cells from turning against the body

August 14, 2014 1:45 pm | by EurekAlert! | Comments

When faced with pathogens, the immune system summons a swarm of cells made up of soldiers and peacekeepers. The peacekeeping cells tell the soldier cells to halt fighting when invaders are cleared. Without this cease-fire signal, the soldiers, known as killer T cells ...

Inside the cell, an ocean of buffeting waves

August 14, 2014 1:40 pm | by EurekAlert! | Comments

Conventional wisdom holds that the cytoplasm of mammalian cells is a viscous fluid, with organelles and proteins suspended within it, jiggling against one another and drifting at random. However, a new biophysical study led by researchers at Harvard University challenges this model....

Scientists use lasers to control mouse brain switchboard

August 14, 2014 1:36 pm | by EurekAlert! | Comments

Ever wonder why it's hard to focus after a bad night's sleep? Using mice and flashes of light, scientists show that just a few nerve cells in the brain may control the switch between internal thoughts and external distractions. The study, partly funded by the National Institutes of Health ...

Stanford professor 1st woman to win top math prize

August 14, 2014 1:30 pm | by Associated Press | Comments

An Iranian-born Stanford University professor is the first woman to win math's highest honor, the Fields Medal. The International Mathematics Union awarded the prize to Maryam Mirzakhani and three others at a meeting in Seoul on Wednesday....

Police to citizens: Be careful what you tweet

August 14, 2014 1:27 pm | by DONNA GORDON BLANKINSHIP, Associated Press | Comments

Police in Washington state are asking the public to stop tweeting during shootings and manhunts to avoid accidentally telling the bad guys what officers are doing. The "TweetSmart" campaign began in late July by a coalition of nine agencies....


Three radars are better than one: Field campaign demonstrates two new instruments

August 14, 2014 8:33 am | by EurekAlert! | Comments

Putting three radars on a plane to measure rainfall may seem like overkill. But for the Integrated Precipitation and Hydrology Experiment field campaign in North Carolina recently, more definitely was better. The three instruments, developed by the High Altitude Radar group ...


Bypass commands from the brain to legs through a computer

August 14, 2014 8:28 am | by EurekAlert! | Comments

Gait disturbance in individuals with spinal cord injury is attributed to the interruption of neural pathways from brain to the spinal locomotor center, whereas neural circuits locate below and above the lesion maintain most of their functions. An artificial connection ...
