EAST LANSING, Mich. — Solar power might be nature's most plentiful and benign source of energy, but shiny black solar cells can lure water insects away from critical breeding areas, a Michigan State University scientist and colleagues warn.

SEATTLE – The bacterium Helicobacter pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix. For years researchers have hypothesized that the bacterium's twisty shape is what enables it to survive – and thrive – within the stomach's acid-drenched environment, but until now they have had no proof.
PITTSBURGH, May 27 – A genetic mutation for inherited lymphedema associated with lymphatic function has been discovered that could help create new treatments for the condition, say researchers at the University of Pittsburgh Graduate School of Public Health. Their findings are reported in the June issue of the American Journal of Human Genetics.
While attempting to solve one mystery about iron oxide-based nanoparticles, a research team working at the National Institute of Standards and Technology (NIST) stumbled upon another one. But once its implications are understood, their discovery* may give nanotechnologists a new and useful tool.
GAINESVILLE, Fla. — The BP oil blowout in the Gulf of Mexico threatens the existence of a critically endangered sawfish and its relative that recently has been proposed to join it as the only two marine fish in United States waters to receive such federal protection, says a University of Florida researcher.
The largetooth sawfish, a popular curio item known for its sawlike snout, was proposed as a federally endangered species on May 7, less than three weeks after massive amounts of oil started gushing into Gulf waters, said George Burgess, a UF ichthyologist and sawfish expert.
Researchers validate a new test for assessing children's and teenagers' fitness to prevent morbidity
Researchers at the UCLA Medical Center found that antiviral therapy during compensated cirrhosis, when compared with all other strategies, is the most cost-effective approach to treating patients with advanced liver disease due to hepatitis C (HCV) infection. Full details appear in the June issue of Liver Transplantation, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases (AASLD).
The title sounds like a crime novel on a dime-store shelf. But "An Invitation to Die" is quite literal in its meaning. And the prime suspect is very, very small.
Rice University evolutionary biologists reported in a paper published this week that the first cells to starve in a slime mold seem to have an advantage that not only helps them survive to reproduce, but also pushes those that keep on eating into sacrificing themselves for the common good.
Researchers at the University of Sheffield have found that there are substantially increased death rates from alcohol-related diseases in socioeconomically deprived areas of England and Wales.
MINNEAPOLIS / ST. PAUL (May 27, 2010) – New research from the University of Minnesota's School of Public Health and Masonic Cancer Center definitively links the use of indoor tanning devices to increased risk of melanoma, the most serious form of skin cancer.
This research study involving 2,268 Minnesotans is the largest of its kind. It found:
BOSTON – A group of "color-coded" laboratory mice are providing researchers with a novel way of tracking T-cells, enabling them to visualize and monitor the cellular immune responses of transplanted tissue in real time. The new imaging system is described in the June issue of Nature Medicine, which appears on-line this week.
London, UK (May 27, 2010) – When we think of ultrasound, it's usually imaging the inside of the body that springs to mind. However, while ultrasound imaging typically requires frequencies that are 50 to 2500 times higher than those human ear can detect, recent increasing evidence indicates that ultrasound at lower frequency can also be used to help certain body tissues to heal and regenerate.
A state-of-the-art heart pump recently approved for use in end-stage cardiac patients has a significantly lower risk for infection than an earlier model of the device, according to researchers at Henry Ford Hospital in Detroit.
A state-of-the-art heart pump, designed to maintain a continuous flow of blood in end-stage cardiac patients with damage to the left side of the heart, also improves function on the right side of the heart, according to researchers at Henry Ford Hospital's Heart and Vascular Institute.
