Mimicking the moon's surface in the basement (August 7, 2010) -- A team of scientists used an ion beam in a basement room at Los Alamos National Laboratory to simulate solar winds on the surface of the moon. The table-top simulation helped confirm that the moon is inherently dry. ... > full story
Timely technology sees tiny transitions (August 7, 2010) -- Scientists can detect the movements of single molecules by using fluorescent tags or by pulling them in delicate force measurements, but only for a few minutes. A new technique will allow them to track single molecules without modifying them -- and it works over longer timescales. ... > full story
Nuclear physicists study 'magic' nature of tin (August 7, 2010) -- The metal tin lacks the value and prestige of gold, silver and platinum, but to nuclear physicists, tin is magic. Physicists recently reported studies on the metal tin that add knowledge to a concept known as magic numbers while perhaps helping scientists to explain how heavy elements are made in exploding stars. ... > full story
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
