Security concerns are one of the key obstacles to the adoption of new non-volatile main memory (NVMM) technology in next-generation computers, which would improve computer start times and boost memory capacity. But now researchers from North Carolina State University have developed new encryption hardware for use with NVMM to protect personal information and other data.

Efficiency is a problem with today's solar panels; they only collect about 20 percent of available light. Now, a University of Missouri engineer has developed a flexible solar sheet that captures more than 90 percent of available light, and he plans to make prototypes available to consumers within the next five years.

These days a bad credit score will get you turned away by a bank, but if you tell a good story about that score, you can improve your chances of getting a microloan from a peer-to-peer lender, according to new research from Rice University and the University of Delaware.

The researchers found that in peer-to-peer lending, unverifiable information such as personal narratives and explanations affected lending decisions above and beyond objective, verifiable information such as credit scores and histories.

OAK RIDGE, Tenn., May 16, 2011 – Billions of dollars lost each year as waste heat from industrial processes can be converted into electricity with a technology being developed at the Department of Energy's Oak Ridge National Laboratory.

The high-efficiency thermal waste heat energy converter actively cools electronic devices, photovoltaic cells, computers and large waste heat-producing systems while generating electricity, according to Scott Hunter, who leads the development team. The potential for energy savings is enormous.

Graduations are a celebration of achievement and growth, but could all the pomp and circumstance increase your risk of exposure to harmful bacteria? A team of researchers from the Johns Hopkins Bloomberg School of Public Health examined the risk of acquiring pathogenic bacteria such as Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) through shaking hands at graduation ceremonies across Maryland. A handshake, a short ritual in which two people grasp one of each other's opposite hands, dates back as far as the 5th century BCE.

Most solid materials are composed of millions of small crystals, packed together to form a fully dense solid. The orientations, shapes, sizes and relative arrangement of these crystals are important in determining many material properties.

There isn't a radio-control handset in sight as several small robots roll briskly up the hallways of an office building. Working by themselves and communicating only with one another, the vehicles divide up a variety of exploration tasks – and within minutes have transmitted a detailed floor map to humans nearby.

U.S. Department of Agriculture (USDA) agronomist Greg McMaster has developed computer software that tells farmers when to spray pesticides. McMaster works at the Agricultural Research Service (ARS) Agricultural Systems Research Unit in Fort Collins, Colo. ARS is USDA's principal intramural scientific research agency.

Getting two fluids to mix in small or confined spaces is a big problem in many industries where, for instance, the introduction of one fluid can help extract another — like water pumped underground can release oil trapped in porous rock — or where the mixing of liquids is the essential point of the process. A key example of the latter is microfluidics technology, which allows for the controlled manipulation of fluids in miniscule channels often only a few hundred nanometers wide.

Plants can overcome their evolutionary legacies to become much better at using biological photosynthesis to produce energy, the kind of energy that can power vehicles in the near future, an all-star collection of biologists, physicists, photochemists, and solar scientists has found.

Computer games are not just for kids. New research published in Journal of NeuroEngineering and Rehabilitation, a BioMed Central open access journal, shows that computer games can speed up and improve a patient's recovery from paralysis after a stroke.

Which is more efficient at harvesting the sun's energy, plants or solar cells? This salient question and an answer are the subject of an article published in the May 13 issue of the journal Science.

Although both photosynthesis and photovoltaics harvest energy from the sun, they operate in distinctly different ways producing different fuels. It is not a simple task to find common ground between the two in order to compare energy conversion efficiency.

Most mechanical resonators damp (slow down) in a well-understood linear manner, but ground-breaking work by Prof. Adrian Bachtold and his research group at the Catalan Institute of Nanotechnology has shown that resonators formed from nanoscale graphene and carbon nanotubes exhibit nonlinear damping, opening up exciting possibilities for super-sensitive detectors of force or mass.

A report commissioned by the US Department of Energy has concluded that a novel University of Colorado Boulder method of producing hydrogen fuel from sunlight is the only approach among eight competing technologies that is projected to meet future cost targets set by the federal agency.
