"For the first time, society is taking scientific predictions like this seriously. We should congratulate ourselves for not only paying attention but taking serious action."
Scientists at Monash University in Australia have developed a process for rapidly and efficiently separating blood plasma at the microscopic level without any moving parts, potentially allowing doctors to do blood tests without sending samples to a laboratory. The technique employs the same principle that Einstein explained when observing the separation of tea leaves in a stirred teacup.
More U.S. high-school students are taking physics than ever before, and the number of physics bachelor's degree recipients in the nation has increased 31 percent since 2000, according to new data presented today by the American Institute of Physics (AIP). In addition, physics bachelor's degree recipients are eight times more likely to go on to earn any kind of PhD than those with non-physics bachelor's, the new data show.
H.

Ray Charles was really good at snapping, says musical acoustician Kenneth Lindsay of Southern Oregon University in Ashland. According to a new computer analysis, Charles's snaps that open his famous song "Fever" with Natalie Cole are timed so well that he is never more than 5 milliseconds off the tight beat, a new study shows.
South Korean researchers have designed and built an inexpensive optical lens that collects light from a large area and produces a virtually distortion-free wide-angle image. Standing in contrast to commonly known "fisheye" lenses, which produce significant amounts of visual distortion, low-distortion wide-angle lenses can potentially improve image-based applications such as indoor security-camera systems and robot navigation.

Students strive to reduce noise-induced hearing loss from personal stereo systems and concerts by inventing projects that detect risky sound levels in music players, and by analyzing their peers' attitudes and beliefs regarding loud noise and their hearing.
At the first-ever conference dedicated to understanding and preventing noise-induced hearing loss in children, researchers will present the first-ever detailed guidelines on safe volume levels for listening to the Apple iPod portable music player with earphones.
Researchers at the University of Missouri-Columbia can now detect the spread of skin cancer cells through the blood by literally listening to their sound. The unprecedented, minimally invasive technique causes melanoma cells to emit noise, and could let oncologists spot early signs of metastases -- as few as ten cancer cells in a blood sample -- before they even settle in other organs.

In an effort to provide safer and more reliable components for aircraft, researchers have invented an optical on-off switch that can replace electrical wiring on airplanes with fiber optics for controlling elevators, rudders, and other flight-critical elements. The technology also has potential applications on the nation's highways, as a "weigh-in-motion" sensor for measuring the weight of fast-moving commercial trucks without requiring them to stop on a scale.

A Scanner Darkly, opening in theaters nationwide today, uses old techniques in a new way to make other-worldly effects pop on the picture screen. Thanks to advances in digital technology and an old animation process called rotoscoping, moviemakers can make motion picture film or video of real, live actors appear as dreamlike as an animation classic.
Health physicists are establishing safe procedures for a promising experimental brain-cancer therapy which uses radioactive scorpion venom. The venom of the yellow Israeli scorpion preferentially attaches to the cells of a type of essentially incurable brain cancers known as gliomas. This preference can be exploited to killing brain cancer cells non-invasively. Information about the study will be presented this week at the Health Physics Society meeting in Providence, RI.

A decision in US federal court today ruled that the concept of "Intelligent Design" does not belong in public school science classrooms. the strong peer-reviewed science of evolution does not conflict with religious belief, many scientists assert, but science belongs in science classes, while religious concepts should be discussed elsewhere.
A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star. By "nulling" out the light of the parent star by exploiting the light's wave nature, remaining reflected light from the planet can be observed in space-based detectors.
A mathematical model predicting the Cy Young award yielded both of the 2005 winners, Chris Carpenter and Bartolo Colon. But the inventors made a small human error they would later regret: before the awards, they overrode the model's AL prediction, choosing Yankees reliever Mariano Rivera rather than the model's choice, Colon"”the actual winner.
Husband-and-wife team combine love of baseball, math to predict sportswriters' voting results.
How many people do airplanes wake up nightly? How different must two drug names sound to prevent doctors and patients from confusing them?
