The device is being developed to sequence DNA at speeds 20,000 times faster than second-generation sequencers currently on the market and will ultimately have a price tag of $100 per genome.
Half of all Americans will be diagnosed at some point in their lives with cancer, the number two killer in the United States. One of the most common types, especially among women, is breast cancer. According to the National Cancer Institute, 192,370 women will be diagnosed with breast cancer in 2009, and more than 40,000 women will die from the disease this year alone.

Task Force on American Innovation to Honor U.S. House Speaker Pelosi with "˜Legislator of the Year Award' for Outstanding Support of Scientific Research.
Salad dressing aside, a pile of spinach has more nutritional value than a wedge of iceberg lettuce. That's because darker colors in leafy vegetables are often signs of antioxidants that are thought to have a variety of health benefits. Now a team of plant physiologists has developed a way to make lettuce darker and redder"”and therefore healthier"”using ultraviolet light-emitting diodes (LEDs).
Sound has a long history in medicine, from the earliest 19th century stethoscopes to the latest ultrasound techniques that image growing fetuses and beating hearts. These days, sound waves are emerging as the basis of many new medical technologies -- helping to deliver genes and drugs to specific tissues, detecting bacterial infections and kidney stones, trimming the prostate, and many other applications. Acoustics is also blending with other disciplines such as neuroscience to help people with speech and hearing problems.

When its rocket lifted off from Cape Canaveral, FL on June 11, 2008, the Fermi Gamma-ray Space Telescope (formerly called GLAST) began its active life with short trip into orbit above the Earth, where it was safely delivered 75 minutes later. From a vantage 350 miles high, the Fermi telescope surveys the entire sky every three hours, detecting gamma rays, the highest-energy light in the universe.
In a recent issue of The Journal of Chemical Physics, published by the American Institute of Physics (AIP), a group of researchers at the University of California, Berkeley and Los Alamos National Laboratory describe the first comprehensive, molecular-level numerical study of gene therapy. Their work should help scientists design new experimental gene therapies and possibly solve some of the problems associated with this promising technique.
Deteriorating screws in bridges, fish that listen in the dark, medical devices that use sound to treat disease, the detected comeback of a long-gone whale, the sound of hyenas, cheese, and bagpipes, and what evolution can teach us about cowardice.
On April 19, CBS aired a "60 Minutes" segment on "cold fusion," a process that proponents claim could solve the world's energy problems. The script stated that "... ["˜60 Minutes'] asked the American Physical Society, the top physics organization in America, to recommend an independent scientist. They gave us Rob Duncan, vice chancellor of research at the University of Missouri and an expert in measuring energy." That statement is false.
From head-banging termites to laughing hyenas, from noisy rocket launches to silent hybrid cars, and from bacteria that cause heart attacks to the acoustics of wind turbines, few fields span as many subjects as acoustics, the study of sound.
The American Institute of Physics (AIP) announces the winners of the 2009 Dannie Heineman Prizes for Mathematical Physics and for Astrophysics.
Sleep is such an essential part of human existence that we spend about a third of our lives doing it -- some more successfully than others. Sleep disorders afflict some 50-70 million people in the United States and are a major cause of disease and injury. People who suffer from disturbed sleep have an increased risk of heart attack, stroke, hypertension, obesity, depression, and accidents. Nearly a fifth of all serious car crashes, in fact, are linked to sleeplessness.
New research described in AIP's the Journal of Chemical Physics may lead to better molecular electronics, ultra-thin materials, and understanding of proteins in the human body.
After about seven months growing in the womb, a human fetus spends most of its time asleep. Its brain cycles back and forth between the frenzied activity of rapid eye movement (REM) sleep and the quiet resting state of non-REM sleep. But whether the brains of younger, immature fetuses cycle with sleep or are simply inactive has remained a mystery, until now.
College Park, MD, April 9, 2009 -- The American Institute of Physics (AIP) announced today that Neal F. Lane, a Rice University professor and former U.S. presidential science advisor, is the winner of AIP's 2008 Karl T. Compton Medal for Leadership in Physics.
Roughly 20 percent of the electricity consumed worldwide is used to light homes, businesses, and other private and public spaces. Though this consumption represents a large drain on resources, it also presents a tremendous opportunity for savings. Improving the efficiency of commercially available light bulbs -- even a little -- could translate into dramatically lower energy usage if implemented widely.
Proton therapy has been hailed as a revolutionary cancer treatment, with higher cure rates and fewer side effects than traditional X-ray photon radiotherapy. Proton therapy is the modality of choice for treating certain small tumors of the eye, head, head or neck. It is also safer -- especially for young children -- because it exposes less of the tissue surrounding a tumor to the dosage, proton therapy lowers the risk of secondary cancers later in life.

These are a few of the topics that will be covered at the 156th meeting of the Acoustical Society of America (ASA) next month in Miami, FL.
Two groups of researchers, one in the United States and one in Australia, are announcing the development of new optical techniques for visualizing the invisible processes at work in several human diseases. The published results are the first to showcase the Optical Society's (OSA) Interactive Science Publishing (ISP) initiative, which allows authors to submit a manuscript that includes large three-dimensional data and gives researchers, scientists and engineers a way to evaluate new research results more thoroughly.
Scientists at Clemson University for the first time have been able to make a practical optical fiber with a silicon core, according to a new paper published in the current issue of the Optical Society's open-access journal, Optics Express. Led by Professor John Ballato and including fiber pioneer Roger Stolen, the team of scientists was able to create this new fiber by employing the same commercial methods that are used to develop all-glass fibers, making silicon fibers viable alternatives to glass fibers for selected specialty applications.
