Vaccine for urinary tract infections is one step closer (November 12, 2010) -- Scientists are one step closer to a vaccine that could prevent a majority of urinary tract infections, which are caused by E. coli bacteria. The researchers studied how bacteria operate in human hosts and discovered key differences between how E. coli genes behave in women and how they behave in mice used in experiments. ... > full story
Scientists demystify an enzyme responsible for drug and food metabolism (November 12, 2010) -- Scientists have solved a 40-year-old puzzle about the mysterious process by which a critical enzyme metabolizes nutrients in foods and chemicals in drugs such as Tylenol, caffeine and opiates. The discovery may help future researchers develop a wide range of more efficient and less-expensive drugs, household products and other chemicals. ... > full story
Scientists explore 1510 influenza pandemic and lessons learned (November 12, 2010) -- History's first recognized influenza pandemic originated in Asia and rapidly spread to other continents 500 years ago, in the summer of 1510. Researcher now explore the 1510 pandemic and what we have learned since then about preventing, controlling and treating influenza. ... > full story
Thousands of turtles captured in Madagascar despite ban (November 12, 2010) -- New research has revealed up to 16,000 endangered turtles are being caught each year by villagers in just one region of Madagascar, despite a government ban. Researchers say the figure, thought to be a conservative estimate, is the first direct assessment of turtle exploitation on the island. ... > full story
Campus-community interventions successful in reducing college drinking (November 12, 2010) -- Heavy drinking among college students results in over 1800 deaths each year, as well as 590,000 unintentional injuries, almost 700,000 assaults and more than 97,000 victims of sexual assaults. In a new study, researchers report on the results of the Safer California Universities study, a successful community-wide prevention strategy targeted at off-campus settings. ... > full story
Modeling autism in a lab dish: Researchers create autistic neuron model (November 12, 2010) -- A collaborative effort between researchers at the Salk Institute for Biological Studies and the University of California, San Diego, successfully used human induced pluripotent stem (iPS) cells derived from patients with Rett syndrome to replicate autism in the lab and study the molecular pathogenesis of the disease. ... > full story
Stem cell transplants in mice produce lifelong enhancement of muscle mass (November 12, 2010) -- Specific types of stem cells transplanted into the leg muscles of mice prevented the loss of muscle function and mass that normally occurs with aging, a finding with potential uses in treating humans with chronic, degenerative muscle diseases. ... > full story
Oldest dinosaur embryos give insights into infancy and growth (November 12, 2010) -- After sitting in collections for nearly 30 years, some remarkably well-preserved dinosaur eggs and their contents are offering new insights into the infancy and growth of early dinosaurs. They represent the oldest embryos of any land-dwelling vertebrate ever found. The eggs, found in 1976 in South Africa, date from the early part of the Jurassic Period, 190 million years ago. They belong to Massospondylus, a member of a group of dinosaurs known as prosauropods that are the ancestors to the later sauropods -- the large, four-legged dinosaurs with long necks, typified by the popular ' Brontosaurus' and Diplodocus. ... > full story
Colorectal cancer risk increases in prostate cancer patients on androgen deprivation therapy, study finds (November 12, 2010) -- Men taking androgen deprivation therapy for prostate cancer may have an increased risk of colorectal cancer, according to a new study. ... > full story
New forms of highly efficient, flexible nanogenerator technology (November 12, 2010) -- Can a heart-implanted micro-robot operate permanently? Can cell phones and tiny robots implanted in the heart operate without having their batteries charged? Such advances may be possible in the near future, thanks to new forms of highly efficient, flexible nanogenerator technology. ... > full story
