UC San Diego computer scientists are one step closer to building low cost networks of underwater sensors for real time underwater environmental monitoring. At the IEEE Reconfigurable Architectures Workshop in Rome, Italy, on May 25, computer scientists from the Jacobs School of Engineering presented a paper highlighting the energy conservation benefits of using reconfigurable hardware rather than competing hardware platforms for their experimental underwater sensor nets.

Immigration officials held a cancer patient for four hours before they allowed him to enter the USA because one of his cancer drugs caused his fingerprints to disappear. His oncologist is now advising all cancer patients who are being treated with the commonly used drug, capecitabine, to carry a doctor's letter with them if they want to travel to the USA.
Soil moisture is essential for seeds to germinate and for crops to grow. But record droughts and scorching temperatures in certain parts of the globe in recent years have caused soil to dry up, crippling crop production. The falling food supply in some regions has forced prices upward, pushing staple foods out of reach for millions of poor people.
WASHINGTON, May 26--Researchers from around the world will present the latest breakthroughs in electro-optics, lasers and the application of light waves at the 2009 Conference on Lasers and Electro-Optics/International Quantum Electronics Conference (CLEO/IQEC) May 31 to June 5 at the Baltimore Convention Center in Baltimore.
RESEARCH HIGHLIGHTS OF THE MEETING:
Seattle – Non-invasive imaging can measure how well patients with the most common form of breast cancer - estrogen receptor positive type - respond to standard aromatase inhibitor therapy after only two weeks and shows similar findings that more invasive needle sampling identifies, according to a poster presentation to be presented at the ASCO annual meeting next week.
Berkeley -- Trying to quit cigarettes but don't know how? A new analysis led by researchers at the University of California, Berkeley, School of Public Health, suggests that Web- and computer-based smoking cessation programs are worth a try, and fortunately during these tough economic times, many of them are free.
Available evidence supports the use of online or other computer-based smoking cessation programs for helping adults quit smoking, according to a meta-analysis of previously published studies appearing in the May 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
"Smoking is the single greatest cause of preventable disease and premature death," the authors write as background information in the article. Currently recommended smoking cessation strategies include individual or group counseling, medications and telephone quit-line counseling.
HOUSTON -- (May 24, 2009) -- Using a specially adapted tool called P[acman], a collaboration of researchers led by Baylor College of Medicine has established a library of clones that cover most of the genome of Drosophila melanogaster (fruit fly) and should speed the pace of genetic research.
One well-known and often deadly consequence of alcohol intoxication is impaired driving. Yet still today, it is difficult for even trained observers to fully identify "intoxication," given that so many factors contribute to it. This review examines the very definition of intoxication, as well as methods designed to prevent impaired driving.
The review will be published in the September issue of Alcoholism: Clinical & Experimental Research and is currently available at Early View.
Nearly 20% of patients with recently diagnosed breast cancer had additional malignant tumors found only by MRI, according to a study performed at Dartmouth Hitchcock Medical Center.
Boston, MA -- A new study from Harvard School of Public Health (HSPH) researchers found that participants who drank for a week from polycarbonate bottles, the popular, hard-plastic drinking bottles and baby bottles, showed a two-thirds increase in their urine of the chemical bisphenol A (BPA). Exposure to BPA, used in the manufacture of polycarbonate and other plastics, has been shown to interfere with reproductive development in animals and has been linked with cardiovascular disease and diabetes in humans.
Chip manufacturers beware: There's a newfound flaw in our understanding of transistor noise, a phenomenon affecting the electronic on-off switch that makes computer circuits possible. According to the engineers at the National Institute of Standards and Technology (NIST) who discovered the problem, it will soon stand in the way of creating more efficient, lower-powered devices like cell phones and pacemakers unless we solve it.
A working definition for cloud computing—a new computer technique with potential for achieving significant cost savings and information technology agility—has been released by a team of computer security experts at the National Institute of Standards and Technology (NIST). Since the federal government is considering cloud computing as a component of its new technology infrastructure, it is NIST's role to evaluate it and then promote its effective and secure use within government and industry by providing technical guidance and developing standards.

Improving communications skills and the use of a simple blood test could help cut the growing number of inappropriate prescriptions of antibiotics, a joint Cardiff University trial has discovered.
