Shining a light on the elusive 'blackbody' of energy research: Designer material has potential applications for thermophotovoltaics (July 23, 2011) -- A designer metamaterial can engineer emitted "blackbody" radiation, a feat that transcends many of the limits governing natural materials and an advance that could potentially lead to the development of new thermophotovoltaic technologies, researchers report. ... > full story
Test for classifying force used in bottle stabbings: New study aids understanding of force required for creating injury (July 23, 2011) -- Engineers in the UK have for the first time created a way of measuring how much force is used during a stabbing using a broken bottle. The advance is expected to have significant implications for legal forensics. ... > full story
Inside the innards of a nuclear reactor: Tiny robots may monitor underground pipes for radioactive leaks (July 22, 2011) -- Scientists have develop robots equipped with cameras that can navigate the underground pipes of a nuclear reactor to check for corrosion by propelling themselves with internal networks of valves and pumps. ... > full story
Astronomers discover largest and most distant reservoir of water yet (July 22, 2011) -- Two teams of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe. Looking from a distance of 30 billion trillion miles away into a quasar -- one of the brightest and most violent objects in the cosmos -- the researchers have found a mass of water vapor that's at least 140 trillion times that of all the water in the world's oceans combined. ... > full story
Smartphone making your eyes tired? Images placed in front of the screen increase visual discomfort (July 22, 2011) -- Several reports indicate that prolonged viewing of mobile devices and other stereo 3-D devices leads to visual discomfort, fatigue and even headaches. According to a new study, the root cause may be the demand on our eyes to focus on the screen and simultaneously adjust to the distance of the content. ... > full story
Chemists create molecular flasks: Researchers design a self-assembling material that can house other molecules (July 22, 2011) -- Recently, researchers at New York University demonstrated an ability to make new materials with empty space on the inside, which could potentially control desired and unwanted chemical reactions. ... > full story
Computer simulations aid understanding of bacterial resistance against commonly used antibiotics (July 22, 2011) -- A recent study into the interactions between aminoglycoside antibiotics and their target site in bacteria used computer simulations to elucidate this mechanism and thereby suggest drug modifications. ... > full story
Software helps synthetic biologists customize protein production (July 22, 2011) -- A software program developed by a Penn State synthetic biologist could provide biotechnology companies with genetic plans to help them turn bacteria into molecular factories, capable of producing everything from biofuels to medicine. ... > full story
Juvenile diarrhea virus analyzed down to the atomic level (July 22, 2011) -- Scientists have used X-ray crystallography to define the structure -- down to the atomic level -- of a common virus that causes juvenile diarrhea. The new research could help direct efforts to develop medications that block the virus before it becomes infectious. ... > full story
New discovery paves the way for using super strong nanostructured metals in cars (July 22, 2011) -- Super strong nanometals are beginning to play an important role in making cars even lighter, enabling them to stand collisions without fatal consequences for the passengers. A student has discovered a new phenomenon that will make nanometals more useful in practice. ... > full story
Ohio Supercomputer Center lifts land speed racer toward 400-mph goal (July 22, 2011) -- A team of engineering students at the Ohio State University's Center for Automotive Research recently began running aerodynamics simulations at the Ohio Supercomputer Center, one of the first steps in the long and careful process of researching, designing, building and racing the fourth iteration of their record-breaking, alternative-fuel streamliner. In partnership with Venturi and A123 Systems, the team began the development process for a completely re-engineered test vehicle designed to break the 400-mph mark. ... > full story
Farthest, largest water mass in universe discovered (July 22, 2011) -- An international team of astronomers has discovered the largest and farthest reservoir of water ever detected in the universe. ... > full story
