Early lung cancer detection: Optical technology shows potential for prescreening patients at high risk (October 9, 2010) -- Early detection is critical for improving cancer survival rates. Yet, one of the deadliest cancers in the United States, lung cancer, is notoriously difficult to detect in its early stages. Now, researchers have developed a method to detect lung cancer by merely shining diffuse light on cells swabbed from patients' cheeks. ... > full story
Microfluidic devices advance 3-D tissue engineering (October 9, 2010) -- A new method that generates three-dimensional (3-D) tissue models for studying bacterial infection of orthopedic implants has been developed. ... > full story
Blind inventors develop free software to enable the blind to use computers (October 9, 2010) -- Inventors have developed free, open-source software to enable blind people to use computers. For many blind people, computers are inaccessible. It can cost upwards of 00 to purchase "screen reader" software, but two blind computer programmers have solved this problem. ... > full story
Cassini catches Saturn moons in paintball fight (October 9, 2010) -- Scientists using data from NASA's Cassini spacecraft have learned that distinctive, colorful bands and splotches embellish the surfaces of Saturn's inner, mid-size moons. The reddish and bluish hues on the icy surfaces of Mimas, Enceladus, Tethys, Dione and Rhea appear to be the aftermath of bombardments large and small. ... > full story
Voice phishing: System to trace telephone call paths across multiple networks developed (October 9, 2010) -- Phishing scams are making the leap from email to the world's voice systems, and researchers have found a way to tag fraudulent calls with a digital "fingerprint" that will help separate legitimate calls from phone scams. ... > full story
Effects of hydrogen on growing carbon nanotubes (October 9, 2010) -- Carbon nanotubes have many potential uses in nanotechnology, optics, electronics, and many other fields. Their exact properties depend on their structure, but controlling that structure, which is determined during their initial formation, is difficult, and scientists do not know precisely how they grow. Researchers now shed new light on the process. ... > full story
Haze on Saturn's moon Titan may hold ingredients for life (October 8, 2010) -- Simulating possible chemical processes in the atmosphere of Titan, Saturn's largest moon, a planetary research team found amino acids and nucleotide bases in the mix -- the most important ingredients of life on Earth. ... > full story
Measurements of CO<sub>2</sub> and CO in China's air indicate sharply improved combustion efficiency (October 8, 2010) -- A collaborative, six-year study of carbon dioxide levels in Beijing and surrounding provinces suggests that combustion efficiency, a component of overall energy efficiency, is improving in the region. The findings are generally consistent with official Chinese government statistics and could bolster their credibility as international negotiations proceed on commitments of China and other nations to combat climate change. ... > full story
Half-time gamblers give stock market insight (October 8, 2010) -- Computer-modeled comparison of online football gamblers' behavior during play and during half-time shows distinct real-time differences, raising the question: What motivates betting behavior when play is not underway? ... > full story
NASA's WMAP project completes satellite operations: Mission observed universe's oldest light (October 8, 2010) -- After nine years of scanning the sky, the Wilkinson Microwave Anisotropy Probe (WMAP) space mission has concluded its observations of the cosmic microwave background, the oldest light in the universe. The spacecraft has not only given scientists their best look at this remnant glow, but also established the scientific model that describes the history and structure of the universe. ... > full story
Bacteria can stand-up and 'walk' (October 8, 2010) -- Researchers have discovered that bacteria are capable of "standing up" and moving while vertical. Apart from being an extraordinary insight into the behavior of bacteria, the findings have important biomedical implications. ... > full story
Tracking device fits on the head of a pin: Mini-gyroscopes to guide smartphones and medical equipment (October 8, 2010) -- A researcher in Israel has developed nano-sized optical gyroscopes that can fit on the head of a pin -- and, more usefully, on an average-sized computer chip -- without compromising the device's sensitivity. These gyroscopes will have the ability to pick up smaller rotation rates, delivering higher accuracy while maintaining smaller dimensions. ... > full story
