A previous six-month study by Iowa State University researchers had indicated that consuming modest amounts of soy protein, rich in isoflavones, lessened lumbar spine bone loss in midlife, perimenopausal women. But now an expanded three-year study by some of those same researchers does not show a bone-sparing effect in postmenopausal women who ingested soy isoflavone tablets, except for a modest effect at the femoral (hip) neck among those who took the highest dosage. http://www.physorg.com/news184962843.html Medicine & Health 2010-02-09T19:10:03-07:00 Seagate today announced worldwide shipments of its Savvio 10K.4 hard disk drive (HDD), the world's highest-capacity and most reliable 2.5-inch enterprise-class drive. http://www.physorg.com/news184964106.html Electronics 2010-02-09T19:10:02-07:00 Scientists have shown that cells' DNA-reading machinery can skim through certain kinds of damaged DNA without skipping any letters in the genetic "text." The studies, performed in bacteria, suggest a new mechanism that can allow bacteria to develop resistance to antibiotics. http://www.physorg.com/news184962719.html Biology 2010-02-09T19:10:01-07:00 A new, more efficient low-cost microring resonator for high speed telecommunications systems has been developed and tested by Professor Roberto Morandotti's INRS team in collaboration with Canadian, American, and Australian researchers.

These tubes or capillaries, formed by a single cell, connect the main tubes of the respiratory system with organs and tissues, thereby providing oxygen. The study has been published in the journal Current Biology. http://www.physorg.com/news184958995.html Biology 2010-02-09T19:00:02-07:00 A sick or sad child might cling to mom's leg.

An important part of the individual difference in personality is due to variation in the underlying genes. One gene, the dopamine receptor D4 gene, however, is known to influence novelty seeking and exploration behaviour in a range of species, including humans and birds. Researchers of the Max Planck Institute for Ornithology in Seewiesen now show that the gene`s influence on birds` behaviour differs markedly between wild populations of great tits.
