Researchers clarify function of glucose transport molecule Researchers at the David Geffen School of Medicine at UCLA have solved the structure of a class of proteins known as sodium glucose co-transporters (SGLTs), which pump glucose into cells. These transport proteins are used in the treatment of chronic diarrhea via oral rehydration therapy, saving the lives of millions of children each year. The solution of the SGLT structure will accelerate development of new drugs designed to treat patients with diabetes and cancer. New study points to agriculture in frog sexual abnormalities A farm irrigation canal would seem a healthier place for toads than a ditch by a supermarket parking lot. But University of Florida 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, UF zoologists have found that toads in suburban areas are less likely to suffer from reproductive system abnormalities than toads near farms - where some had both testes and ovaries. Parasite vaccines within reach Even though parasites are complex creatures, the mammalian immune response to them is surprisingly simple, leading University of California, Berkeley, researchers to predict that creating vaccines for parasitic diseases such as malaria may be more straightforward than initially thought. Red wine ingredient wards off effects of age on heart, bones, eyes and muscle Large doses of a red wine ingredient can ward off many of the vagaries of aging in mice who begin taking it at midlife, according to a new report published online on July 3rd in Cell Metabolism, a Cell Press publication. Those health improvements of the chemical known as resveratrol—including cardiovascular benefits, greater motor coordination, reduced cataracts and better bone density—come without necessarily extending the animals' lifespan. Geologists push back date basins formed, supporting frozen Earth theory Even in geology, it's not often a date gets revised by 500 million years. But University of Florida geologists say they have found strong evidence that a half-dozen major basins in India were formed a billion or more years ago, making them at least 500 million years older than commonly thought. GoLive2 Introduces a Wiimote for PC Games For all Wii-lovers out there, GoLive2 has recently announced the Stix, a motion-sensing remote control that can be used to play PC games. Case dropped against parents who put baby on eBay (AP) -- A baby boy removed from his parents' custody after they offered to sell him on eBay for just a euro - $1.59 - as a joke is back at home, a prosecutor said Thursday. EU musicians oppose Europe-wide online licensing (AP) -- The Bee Gees' Robin Gibb and other European music composers warned Thursday that standardizing music royalties across Europe could hurt musicians and the songs they write. Researchers identify tumor suppressor that manages cellular cleaning and recycling proceses Researchers at the University of Southern California (USC) have identified a specific tumor suppressor that manages membrane traffic routes for cellular cleaning and recycling. New antibiotic beats superbugs at their own game The problem with antibiotics is that, eventually, bacteria outsmart them and become resistant. But by targeting the gene that confers such resistance, a new drug may be able to finally outwit them. Rockefeller University scientists tested the new drug, called Ceftobiprole, against some of the deadliest strains of multidrug-resistant Staphylococcus aureus (MRSA) bacteria, which are responsible for the great majority of staphylococcal infections worldwide, both in hospitals and in the community. ... |
