Selenium makes more efficient solar cells (August 6, 2010) -- By embedding the element selenium in zinc oxide, researchers have made a relatively inexpensive material that could be promising for solar power conversion by making more efficient use of the sun's energy. ... > full story
Reading zip codes of 3,500-year-old letters: Non-destructive X-ray scanning of archaeological finds (August 6, 2010) -- A researcher in Israel uses a hand-held device based on x-ray fluorescence, a device that can be found in many chemistry labs, to non-destructively ascertain the chemical composition of ancient tablets. Using an index that he's developed, he can determine the geographical origin of coins, ancient plasters, glass and tablets to investigate the secrets of ancient history. ... > full story
Robot climbs walls (August 6, 2010) -- Wielding two claws, a motor and a tail that swings like a grandfather clock's pendulum, a small robot named ROCR ("rocker") scrambles up a carpeted, 8-foot wall in just over 15 seconds -- the first such robot designed to climb efficiently and move like human rock climbers or apes swinging through trees. ... > full story
'Asynchronous telepsychiatry' found effective for assessing patients' mental health (August 6, 2010) -- A new study has found that psychiatrists can accurately assess a patient's mental health by viewing videotaped interviews that are sent to them for consultation and treatment recommendations. ... > full story
Artificial bee eye gives insight into insects’ visual world (August 6, 2010) -- Despite their tiny brains, bees have remarkable navigation capabilities based on their vision. Now scientists have recreated a light-weight imaging system mimicking a honeybee's field of view, which could change the way we build mobile robots and small flying vehicles. ... > full story
Nanofluidic 'multi-tool' separates and sizes nanoparticles (August 6, 2010) -- Researchers have engineered a nanoscale fluidic device that functions as a miniature "multi-tool" for working with nanoparticles-objects whose dimensions are measured in nanometers, or billionths of a meter. ... > full story
Quantum networks advance with entanglement of photons, solid-state qubits (August 5, 2010) -- A team of physicists has achieved the first-ever quantum entanglement of photons and solid-state materials. The work marks a key advance toward practical quantum networks, as the first experimental demonstration of a means by which solid-state quantum bits, or "qubits," can communicate with one another over long distances. ... > full story
Computer scientists build 'pedestrian remover' (August 5, 2010) -- Imagine encountering leashed dogs without dog walkers, or shoes filled just with ankles -- when scoping out potential apartments using Google Street View. These are the sorts of visual hiccups that an experimental computer vision system occasionally generates when it automatically removes individual pedestrians from images that populate Google Street View. ... > full story
Unprecedented look at oxide interfaces reveals unexpected structures on atomic scale (August 5, 2010) -- Thin layers of oxide materials and their interfaces have been observed in atomic resolution during growth for the first time by researchers, providing new insight into the complicated link between their structure and properties. ... > full story
Physicists use offshoot of string theory to describe puzzling behavior of superconductors (August 5, 2010) -- Physicists have now used the connection between quantum and gravitational mechanics, known as gauge/gravity duality to describe a specific physical phenomenon -- the behavior of a type of high-temperature superconductor, or a material that conducts electricity with no resistance. ... > full story
Seeing a stellar explosion in 3D (August 5, 2010) -- Astronomers using ESO's Very Large Telescope have for the first time obtained a three-dimensional view of the distribution of the innermost material expelled by a recently exploded star. The original blast was not only powerful, according to the new results. It was also more concentrated in one particular direction. This is a strong indication that the supernova must have been very turbulent, supporting the most recent computer models. ... > full story
Invisibility cloak advance: New findings promising for 'transformation optics' (August 5, 2010) -- Researchers have overcome a fundamental obstacle in using new "metamaterials" for radical advances in optical technologies, including ultra-powerful microscopes and computers and a possible invisibility cloak. ... > full story
