Agriculture Linked To Frog Sexual Abnormalities (July 5, 2008) -- A farm irrigation canal would seem a healthier place for toads than a ditch by a supermarket parking lot. But scientists have found the opposite is true. In a study with wide implications for a longstanding debate over whether agricultural chemicals pose a threat to amphibians, zoologists have found that toads in suburban areas are less likely to suffer from reproductive system abnormalities than toads near farms -- where some individual animals had both testes and ovaries. ... > full story
Bone Marrow Alternative: Stem Cells From Umbilical Cord May Be Used To Treat Hepatic Diseases (July 5, 2008) -- Researchers from the Universities of Granada and León have shown that mononuclear blood cells from human umbilical cord can be an effective alternative to bone marrow. This work, to be published in the journal Cell Transplantation, could potentially mean a great advance in regenerative hepatic medicine. ... > full story
Mercury's Surface Dominated By Volcanism And Iron-deficiency (July 5, 2008) -- Multispectral data on the composition of rock untis of the surface of Mercury show a widespread role for volcanism and an apparent deficiency in iron in the rocks' minerals. ... > full story
Women Over 90 More Likely To Have Dementia Than Men (July 5, 2008) -- Women over 90 are significantly more likely to have dementia than men of the same age, according UC Irvine researchers involved with the 90+ Study, one of the nation's largest studies of dementia and other health factors in the fastest-growing age demographic. ... > full story
Undergraduates Forge New Area Of Bioinformatics (July 5, 2008) -- A group of undergraduate students have forged a new area of bioinformatics that may improve genomic and proteomic annotations and unlock a collection of stubborn biological mysteries. Their work will be published in the journal Genome Research. ... > full story
Scientists Set Out To Measure How We Perceive Naturalness (July 5, 2008) -- Scientists at the National Physical Laboratory are working towards producing the world's first model that will predict how we perceive naturalness. The results could help make synthetic products so good that they are interpreted by our senses as being fully equivalent to the "real thing," but with the benefits of reduced environmental impact and increased durability. ... > full story
Music Went With Cave Art In Prehistoric Caves (July 5, 2008) -- Thousands of years later, we can view stone-age art on cave walls, but we can't listen to the stone-age music that would have accompanied many of the pictures. Researchers report that the most acoustically resonant place in a cave -- where sounds linger or reverberate the most -- was also often the place where the pictures were densest. In many sites, flutes made of bone are to be found nearby. ... > full story
Seizures In Newborns Can Be Detected With Small, Portable Brain Activity Monitors (July 5, 2008) -- Compact, bedside brain-activity monitors detected most seizures in at-risk infants. That means the compact units could assist clinicians in monitoring for electrical seizures until confirmation with conventional EEG, the researchers assert in an article in Pediatrics. ... > full story
Puzzle In The Control Of Cell Division Unraveled (July 5, 2008) -- A puzzle in the control of cell division, one of the most fundamental processes in all biology, has been unraveled. Although the steps of cell division are familiar to all pupils studying biology in schools, the details of how cell division is controlled and errors avoided have still to be sorted out. ... > full story
Coronary Arterial Calcium Scans Help Detect Overall Death Risk In The Elderly (July 5, 2008) -- Measuring calcium deposits in the heart's arteries can help predict overall death risk in American adults, even when they are elderly, according to a new study in the Journal of the American College of Cardiology. ... > full story
Researchers Use Supercomputer To Track Pathways In Myoglobin (July 5, 2008) -- Myoglobin is responsible for oxygen storage in cells. But how does oxygen travel through the solid protein wall to be anchored by an iron atom deep within the protein? Scientists have now provided a computational solution to the decades-old puzzle. ... > full story
Weight Watchers Vs. Fitness Centers (July 5, 2008) -- The nationally known commercial weight loss program, Weight Watchers, was compared to gym membership programs to find out which method wins in the game of good health. Researchers examined the real-life experiences of participants to determine which program helps people lose pounds, reduce body fat and gain health benefits. ... > full story
