With first neutrino events, physicists closer to answering why only ma
Physicists have just announced that they have detected the first neutrino events generated by the newly built neutrino beam at the J-PARC accelerator laboratory in Tokai, Japan. Neutrino oscillations, which require neutrinos to have mass and therefore were not allowed in previous theoretical understanding of particle physics, probe new physical laws and are of great interest in the study of the fundamental constituents of matter. There are lasers, and then there are compact, multibeam, multi-wavelen
Scientists have demonstrated compact, multibeam, and multi-wavelength lasers emitting in the invisible part of the light spectrum (infrared). By contrast, typical lasers emit a single light beam of a well-defined wavelength. The innovative multibeam lasers have potential use in applications related to remote chemical sensing pollution monitoring, optical wireless, and interferometry. Geologists Make Better Estimates Of Rock Ages, Study Global Climate Ch
Ohio State University geologists have found that important rocks from Niagara Gorge -- rock formations that are used to judge the ages of rocks and fossils around North America -- formed five times faster than previously thought. The finding means that scientists will have to re-examine studies of sedimentary rock deposited across North America during the Silurian period, from 416 to 443 million years ago. To Catch An Intermediate: Scientists Find New Way To Trap And Hold Int
A new technique for capturing the short-lived but critical "intermediate"compounds that help carry chemical reactions which take place in aqueous solution from their starting point to the final product has been developed by researchers with the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab). This technique basically entails temporarily trapping the elusive transients inside molecular pyramids. Mayo Researchers Seek Methods To Make New Cancer Therapies Available M
In their efforts to explore more effective and efficient ways to conduct clinical trials, Mayo Clinic cancer researchers will present new recommendations about how long studies should track results when evaluating new cancer therapies. Robotic Crawler Detects Wear In Power Lines
To your left runs a high-voltage power cable that is worn, but still physically sound. To your right runs a cable that looks identical, but damaged insulation means the cable is vulnerable to a short. Can you tell the difference? Even most power companies don't know the weak points in their electrical grids. And although lights get turned on after a storm, the long-term effects of hurricanes, landslides or wind storms lie unnoticed. Now a robot can roll along the miles of cable, performing a utilities' equivalent of check-ups. Mary Ellen Pleasant
"This site is dedicated to accurate presentation of the life of Mary Ellen Pleasant, called the 'Mother of Civil Rights in California.' ... We also support the work of scholar/performer Susheel Bibbs, who ... has re-researched Pleasant's life and is presenting it accurately for the first time."The site features an illustrated biography of Pleasant, including information about her study with Voodoo Queen Marie LaVeaux. Also includes information about Bibb's chautauqua performances and related activities. What Factors Are Associated With Survival In Advanced Laryngeal Cancer
Type of treatment, sex, race and insurance status are associated with survival rates among patients with advanced laryngeal cancer, according to a new article. How can some athletes play on through intense pain?
How can some sportsmen and women, in the heat of the moment, play on through pain that would floor anyone else? Bert Trautmann, the Manchester City goalkeeper, famously played on through to the end of the 1956 FA Cup final -- holding on for a 3-1 win -- despite suffering a broken neck from a collision in the second half. Health-care Workers' SARS Protective Clothing Systems
Health-care workers who don protective clothing to stave-off infection from threats such as SARS, other emerging infectious diseases, and bioterrorism are still vulnerable to contamination, a Queen's University study has found.
