New Laser Provides Spectrum Of Sensing Data
Like artists, scientists use color to paint clearer pictures of the things -- everything from combustion gases to cancer cells -- they study. And as a result of a new laser system that rapidly delivers a pulsed rainbow of colors, those pictures will contain more information than ever before. Mechanical Engineering Assistant Professor Scott Sanders developed the system, which is highlighted in the cover story of the May issue of Optics and Photonics News. Gene's Activity Points To More Lethal Subtype Of Acute Myeloid Leukemi
A new study shows that the activity of a particular gene can identify people who have a more lethal form of acute myeloid leukemia, singling out those patients who should receive more intense therapy. The gene, called ERG (for ETS-related gene), has also been linked to chronic leukemia and to breast and prostate cancer. Arctic Ice Meltdown Continues With Significantly Reduced Winter Ice Co
As far as temperatures drop in the Arctic winter, a new study shows that in the last two years sea ice is shrinking on the surface of Arctic waters to record low levels. Using satellite data, scientists have observed unusually warm wintertime temperatures in the region and a resulting decline in the length of the Arctic ice season. Scientists Unveil Piece Of HIV Protein That May Be Key To AIDS Vaccine
In a finding that could have profound implications for AIDS vaccine design, researchers led by a team at the NIAID have generated an atomic-level picture of a key portion of an HIV surface protein as it looks when bound to an infection-fighting antibody. Unlike much of the constantly mutating virus, this protein component is stable and -- more importantly, say the researchers -- appears vulnerable to attack from this specific antibody, known as b12, that can broadly neutralize HIV. Study Identifies Energy Efficiency As Reason For Evolution Of Upright
A new study provides support for the hypothesis that walking on two legs, or bipedalism, evolved because it used less energy than quadrupedal knucklewalking. Humans walking on two legs only used one-quarter of the energy that chimpanzees who knuckle-walked on four legs did. Alcohol Consumption Linked To HIV Disease Progression, Study Shows
Researchers have found a link between alcohol consumption and HIV disease progression in HIV-infected persons. Alcohol use is common among HIV-infected persons, and its impact on HIV disease progression has been examined in in-vitro, animal and human studies. Alcohol may adversely affect immunologic function in HIV-infected persons by various mechanisms, including increased HIV replication in lymphocytes. Popular Mechanics: Geek the Vote 2008
Coverage of the 2008 U.S. presidential election with an emphasis on science and technology issues. Find candidate proposals for issues such as automotive technology, digital privacy, energy, climate change, firearms, and infrastructure. Also includes related election news. From the website for Popular Mechanics magazine. Restless Legs Genetics On The Move
Anybody who suffers from restless legs syndrome (RLS) is bothered by unpleasant sensations in the legs at night, the only remedy for which is moving. It has always been completely unclear what triggers this condition. Scientists have finally identified sequence variants in the genome, which are more frequent in RLS patients than in the normal population. For the first time ever this allowed insights into the underlying cause of this disease. Pigeons Provide Clue To Solving Common Problem In Heart Patients
Through studying pigeons with genetic heart disease, researchers at Wake Forest University School of Medicine have discovered a clue about why some patients' heart vessels are prone to close back up after angioplasty. Jupiter's Moon Europa Should Be NASA's Next Target, Says Researcher
As NASA develops its next "flagship"mission to the outer solar system, Jupiter's enigmatic moon Europa should be the target, says Arizona State University professor Ronald Greeley. Although Europa lies five times farther from the Sun than Earth, he notes it may offer a home for life. He is presenting the Europa proposal today (February 18) at the annual meeting of the American Association for the Advancement of Science in San Francisco.
