Physicists break color barrier for sending, receiving photons (October 2, 2010) -- Scientists have invented a method to change the color of single photons in a fiber optic cable. The laser-tweaked feat could be a quantum step forward for transferring and receiving high volumes of secured data for future generations of the Internet. ... > full story
Lightweight construction materials: Suitable for car wheels? (October 2, 2010) -- Are lightweight construction materials suitable for extremely stressed and safety-relevant components such as car wheel? Tests and calculations show that fiber-reinforced plastics are highly damage-tolerant and distinctly superior to aluminum in car wheels. Researchers have already produced a prototype lightweight wheel. ... > full story
Catalyst sandwich: Synthetic PCR mimic could lead to highly sensitive medical, environmental diagnostics (October 2, 2010) -- Researchers have taken another step towards realizing a new class of PCR enzyme mimics, opening the door for the development of highly sensitive chemical detection systems that go beyond nucleic acid targets. The blueprint for building synthetic structures to detect and signal the presence of targets such as small molecule medical analytes and environmental hazards is inspired by biology. The method also could be useful in catalysis and the production of polymers. ... > full story
Underwater robot swims free thanks to wireless controller (October 1, 2010) -- A waterproof controller is allowing an underwater robot, dubbed "AQUA," to go "wireless." While underwater, divers can program the tablet to display tags onscreen, similar to barcodes read by smartphones. The robot's on-board camera scans these tags to receive and carry out commands. ... > full story
Three solid-state qubits entangled: Big step toward quantum error correction (October 1, 2010) -- A research team has achieved the quantum entanglement of three solid-state qubits, or quantum bits, for the first time. Their accomplishment represents the first step towards quantum error correction, a crucial aspect of future quantum computing. ... > full story
New way to view atomic motion of proteins invented (October 1, 2010) -- Using myoglobin, physicists have developed a new way to peer into the inner workings of proteins and detect which specific atoms are at work. ... > full story
Knot in the ribbon at the edge of the solar system 'unties' (October 1, 2010) -- The unusual "knot" in the bright, narrow ribbon of neutral atoms emanating in from the boundary between our solar system and interstellar space appears to have "untied," according to new research. ... > full story
Simple approach could clean up oil remaining from Exxon Valdez spill (October 1, 2010) -- Traces of crude oil that linger on the shores of Alaska's Prince William Sound after the Exxon Valdez oil spill remain highly biodegradable, despite almost 20 years of weathering and decomposition, scientists are reporting in a new study. Their findings suggest a simple approach for further cleaning up remaining traces of the Exxon Valdez spill -- the largest in US waters until the 2010 Deepwater Horizon episode. ... > full story
Spring on Titan brings sunshine and patchy clouds (October 1, 2010) -- The northern hemisphere of Saturn's moon Titan is set for mainly fine spring weather, with polar skies clearing since the equinox in August last year. The visual and infrared mapping spectrometer (VIMS) aboard NASA's Cassini spacecraft has been monitoring clouds on Titan regularly since the spacecraft entered orbit around Saturn in 2004. Now, researchers have analyzed more than 2,000 VIMS images to create the first long-term study of Titan's weather using observational data that also includes the equinox. ... > full story
Finding a buckyball in a photovoltaic cell (October 1, 2010) -- A new technique analyzes the reflection of neutrons to locate buckyballs within composite materials. The work may lead to more effective research on photovoltaic devices. ... > full story
'e-SMART' technologies may help young adults self-manage mental illness (October 1, 2010) -- While many young adults will share the details of their daily lives with dozens -- sometimes hundreds -- of friends on Facebook, communicating with their health care providers about mental illness is another story. A researcher is now developing new patient communications tools, using computer-based techniques to reach young adults already tied to their technology devices. ... > full story
Researchers find phone apps sending data without notification; TaintDroid tool IDs untrustworthy apps (October 1, 2010) -- TaintDroid, a prototype extension to the Android mobile-phone platform designed by researchers, recently identified that 15 of 30 randomly selected, popular, free Android Marketplace applications sent users' private information to remote advertising servers and two-thirds of the apps handled data in ambiguous ways. ... > full story
