The same results also were achieved ... http://www.newscitech.com/lost-memories-may-prove-merely-inaccessible/ Oxford scientists have for the first time revealed a link between a gene and the activity of human stem cells, giving hope that stem cell transplant success for blood cancer patients may be significantly improved. A team at the MRC www.mrc.ac.uk Molecular Haematology Unit at Oxford Universityhas found that a gene ... http://www.newscitech.com/new-gene-discovered-in-human-stem-cells-may-benefit-transplant-patients/ A major study sheds new light on the role of carbon dioxide once it's transported to the oceans' depths. The research indicates that instead of sinking, carbon dioxide is often consumed by animals and bacteria and recycled in the "twilight zone," a dimly lit area 100 to 1,000 meters below ... http://www.newscitech.com/oceans-twilight-zone-may-be-a-key-to-understanding-climate-change/ Before fish began to invade land, about 365 million years ago, they had some big problems to solve. They needed to come up with new ways to move, breathe, and eat. Take the latter, for example. Fish usually pucker up and suck prey into their mouths. But air is 900 times ... http://www.newscitech.com/when-fish-first-started-biting/ A protein acting as a long-distance signal from leaf to shoot-tip tells plants when to flower, says new research published in Science Express on Thursday 19 April 2007. The study reveals the likely mechanism by which the Arabidopsis plant flowers in response to changes in day length. Earlier research had shown ... http://www.newscitech.com/scientists-unlock-secret-of-what-makes-plants-flower/ Scientists using one of the nation's newest and most capable research aircraft are launching a far-reaching field project this month to study plumes of airborne dust and pollutants that originate in Asia and journey to North America. The plumes are among the largest such events on Earth, so great in scope ... http://www.newscitech.com/scientists-track-impact-of-asian-dust-and-pollution-on-clouds-climate-change/ In the first nationally representative study to examine the relationship between survey measures of household firearm ownership and state-level rates of suicide in the United States, researchers at the Harvard School of Public Health (HSPH) found that suicide rates among children, women, and men of all ages are higher in ... http://www.newscitech.com/hsph-study-shows-guns-in-homes-linked-to-higher-rates-of-suicide/ Bugs in the gut are known as gut microbes and they live symbiotically in human and animal bodies, playing an important role in metabolism. Abnormalities in some types of gut microbes have recently been linked to diseases such as diabetes and obesity. Today's research, published in the Journal of Proteome Research, ... http://www.newscitech.com/dog-study-sheds-new-light-on-why-dietary-restriction-can-lead-to-a-longer-life/ Scientists have confirmed the existence of protein in soft tissue recovered from the fossil bones of a 68 million-year-old Tyrannosaurus rex (T. rex) and a half-million-year-old mastodon. Their results may change the way people think about fossil preservation and present a new method for studying diseases in which identification of proteins ... http://www.newscitech.com/ancient-t-rex-and-mastodon-protein-fragments-discovered-sequenced/
