(PhysOrg.com) -- Researchers have created a new type of optical device small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers.

(PhysOrg.com) -- Researchers from the National Renewable Energy Laboratory (NREL) have reported the first solar cell that produces a photocurrent that has an external quantum efficiency greater than 100 percent when photoexcited with photons from the high energy region of the solar spectrum.

(PhysOrg.com) -- Two Madrid scientists from The Complutense University think they have an algorithm that may impact the nature of the world's leading search engine. In essence, they are saying Hey, world, Google This. "We have found an instance of this class of quantum protocols that outperforms its classical counterpart and may break the classical hierarchy of web pages depending on the topology of the web," say the researchers.

Researchers at the Massachusetts Institute of Technology (M.I.T.) have developed an imaging system that can acquire visual data at a rate of one trillion exposures per second–fast enough to produce a slow-motion video of a burst of light traveling the length of a one-liter bottle, bouncing off the cap and reflecting back to the bottle’s bottom. As Ramesh Raskar, an associate professor in M.I.T.’s Media Lab, explains in the video below, a high-speed camera can capture the image of a bullet mid-flight. The M.I.T

(PhysOrg.com) -- Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and the Universidad San Francisco de Quito in Ecuador have found that, at just the right temperatures, nanoclusters form and improve the flow of electrical current through certain oxide materials.

Psychologists warn that stated beliefs and actual behavior often don't match up when it comes to innovation. Among young entrepreneurs , creativity is like gold, with just about every aspiring business owner proudly honing their reputation as an innovator. Of course this makes sense—no one is going to pay for the same old thing they have already

What would be a case for the repair shop for a car engine is completely normal for a micro engine. If it sputters, this is caused by the thermal motions of the smallest particles, which interfere with its running

The Beryl Companies' chief executive offers three steps to establish employee enthusiasm and confidence. A recent human resources study found that an alarming 70 percent of workers feel disengaged from their jobs

A team of scientists working at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has found that increasing the amount of lithium coating in the wall of an experimental fusion reactor greatly improves the ability of experimentalists to contain the hot, ionized gas known as plasma. Adding more lithium also enhances certain plasma properties aiding the reaction, the researchers found.

Photos taken by the researchers show plasma arcs up to 60 meters long casting an eerie blue glow over buildings and trees at the High Voltage Laboratory at the University of Canterbury in New Zealand.

A recent study showed that certain brain areas expand in people who have greater numbers of friends on Facebook . This was welcome news for online social network addicts, particularly teenagers : "Mom, I'm not just on Facebook ; I'm doing my temporal lobe calisthenics." There was a problem, though

(PhysOrg.com) -- Researchers from the NIST Center for Nanoscale Science and Technology have led the development of a new technique for efficiently out-coupling photons from epitaxially-grown quantum dots directly into a standard single-mode optical fiber.

Aiming to take "clean" to a whole new level, researchers at the University of California at Berkeley and the University of Maryland at College Park have teamed up to study how low-temperature plasmas can deactivate potentially dangerous biomolecules left behind by conventional sterilization methods.
