Solar energy gets a boost

July 8, 2014 3:04 pm | by EurekAlert! | Comments

A perspective article published last month by University of California, Riverside chemists in the Journal of Physical Chemistry Letters was selected as an Editors Choice—an honor only a handful of research papers receive. The perspective reviews the chemists' work on "singlet fission," a process in which a single photon generates a pair of excited states....

A hotspot for powerful cosmic rays

July 8, 2014 2:59 pm | by EurekAlert! | Comments

An observatory run by the University of Utah found a "hotspot" beneath the Big Dipper emitting a disproportionate number of the highest-energy cosmic rays. The discovery moves physics another step toward identifying the mysterious sources of the most energetic particles in the universe....

Bioelectronics could lead to a new class of medicine

July 7, 2014 3:35 pm | by EurekAlert! | Comments

Imagine having tiny electronics implanted somewhere in your body that can regulate nerve signals and make symptoms of various disorders go away. That's the vision of the field of bioelectronic medicine — the emerging discipline that has made enough promising advances to draw a big investment by a pharmaceutical giant....

Finding real value in big data for public health

July 7, 2014 3:28 pm | by EurekAlert! | Comments

Media reports of public health breakthroughs made possible by big data have been largely oversold, according to a new study, published today in the American Journal of Preventive Medicine. "Many studies deserve praise for being the first of their kind....

Toward a new way to keep electronics from overheating

July 7, 2014 3:21 pm | by EurekAlert! | Comments

Computer technology has transformed the way we live, but as consumers expect ever more from their devices at faster speeds, personal computers as well as larger electronic systems can overheat. This can cause them to slow down, or worse, completely shut down....

Inspired by nature, researchers create tougher metal materials

July 7, 2014 3:19 pm | by EurekAlert! | Comments

Drawing inspiration from the structure of bones and bamboo, researchers have found that by gradually changing the internal structure of metals they can make stronger, tougher materials that can be customized for a wide variety of applications – from body armor to automobile parts....

The time devoted to both conventional and social media each day is growing

July 7, 2014 3:14 pm | by EurekAlert! | Comments

Smartphones have made it far easier for people to find and exchange information and to make their views heard. In 2010, 14 per cent of the people of Sweden had access to a smartphone; three years later, in 2013, the figure is 67 per cent. More time is devoted to both online editions of traditional media and social media....

A million times better

July 7, 2014 1:19 pm | by EurekAlert! | Comments

Lasers have a fixed place in many fields of application. Yet, there are still wavelengths for which either no systems exist, or at best only large and expensive ones. On the other hand remote sensing and medical applications call for compact laser systems....

Power consumption of robot joints could be 40 perecnt less, according to a laboratory study

July 7, 2014 11:13 am | by EurekAlert! | Comments

Let us imagine, for a moment, the arm of a robot that lifts a cup of coffee to its "lips" over and over again. The joint of this robotic arm needs a certain flexibility plus an electric motor to drive the upward and downward movements. So orders have to be sent to the motor so that the joint can perform the corresponding movements....
