Graphene organic photovoltaics: Flexible material only a few atoms thick may offer cheap solar power (July 24, 2010) -- A research team has produced flexible transparent carbon atom films that the researchers say have great potential for a new breed of solar cells. ... > full story
Virtual reality gives insight on protein structures (July 24, 2010) -- To understand a protein, it helps to get inside of it, and a professor has now figured out a way to do so. A new computer software program and projection system lets a person look at larger-than-life, 3-D structures of proteins in virtual reality. This allows scientists to walk inside, through or around the protein of interest for investigating its structure and function. ... > full story
NASA spacecraft camera yields most accurate Mars map (July 24, 2010) -- A camera aboard NASA's Mars Odyssey spacecraft has helped develop the most accurate global Martian map ever. Researchers and the public can access the map via several websites and explore and survey the entire surface of the Red Planet. ... > full story
Charging up electric car batteries in environmentally-friendly way (July 24, 2010) -- Electromobility makes sense only if car batteries are charged using electricity from renewable energy sources. But the supply of green electricity is not always adequate. An intelligent charging station can help, by adapting the recharging times to suit energy supply and network capacity. ... > full story
Out of the gait: Robot ranger sets untethered 'walking' record at 14.3 miles (July 23, 2010) -- The loneliness of the long-distance robot: A robot named Ranger walked 14.3 miles in about 11 hours, setting an unofficial world record. A human -- armed with nothing more than a standard remote control for toys -- steered the untethered robot. ... > full story
Cancer-metabolism link runs deep in humans, novel network algorithm suggests (July 23, 2010) -- Eighty years ago, the medical establishment believed cancer was caused by a dysfunction of metabolism, but the idea went out of vogue. Now, scientists are again looking at metabolism and its role in cancer and other common diseases. ... > full story
Supercomputer reproduces a cyclone's birth, may boost forecasting (July 23, 2010) -- Scientists have employed NASA's Pleiades supercomputer and atmospheric data to simulate tropical cyclone Nargis -- with the first model to replicate the formation of the tropical cyclone five days in advance. ... > full story
How do cells die? Biophotonic tools reveal real-time dynamics in living color (July 23, 2010) -- Apoptosis, programmed cell death, is essential to normal development, healthy immune system function, and cancer prevention. The process dramatically transforms cellular structures but the limitations of conventional microscopy methods have kept much about this structural reorganization a mystery. ... > full story
Nanoparticles as destructive beacons to zap tumors (July 23, 2010) -- A group of researchers is developing a way to treat cancer by using lasers to light up tiny nanoparticles and destroy tumors with the ensuing heat. ... > full story
New technique for studying dark energy (July 23, 2010) -- A new but technically challenging observational "shortcut" will help make large-scale cosmic maps that can yield clues to to the nature of the mysterious "dark energy" that pervades the universe. ... > full story
New quantum state of matter discovered in Heusler compounds: Applications in spintronics, quantum computing and new physical effects (July 23, 2010) -- Scientists have been researching Heusler compounds, which are an important material class for the use in spintronic applications. Over the past few years, new application areas have emerged in the field of renewable energy, such as solar energy and thermoelectrics. And now Heusler compounds are also being considered for future technologies such as quantum computers. ... > full story
Transparency through open notes: Risks and rewards of inviting patients to review their medical records (July 23, 2010) -- Technology has placed vast amounts of medical information literally a mouse click away. Yet what often may be central -- a doctor's notes about a patient visit -- has traditionally not been part of the discussion. In effect, such records have long been out of bounds. In a new article, researchers speculate about the risks and rewards of making clinicians' notes transparent to patients. ... > full story
