(PhysOrg.com) -- European researchers are making an impressive effort to link up digital repositories to create a vast network of easy to search online data. The DRIVER project work - one of the largest efforts of its kind - aims to make some sense and better use of the growing online digital world, the 'data-sphere'. http://www.physorg.com/news172821794.html Technology Tue, 22 Sep 2009 07:20:03 EST news172821794 Small-bowel transplant patients with an ileostomy -- an opening into their small bowel -- have a very different population of bacteria living in their gut than patients whose ileostomy has been closed, researchers from UC Davis and Georgetown University Medical Center have found.

Researchers at the Swiss Tropical Institute, Basel, Switzerland, and the Noguchi Memorial Institute for Medical Research, Legon, Ghana, developed SNP typing assays to systematically profile genetic diversity among M. ulcerans isolates by sequencing and comparing the genomes of selected strains. http://www.physorg.com/news171865147.html Biology Fri, 11 Sep 2009 05:30:01 EST news171865147 Wheat experts from 26 countries warn that rapidly-moving, wind-borne transboundary wheat diseases continue to threaten food security and wheat genetic diversity worldwide - particularly in the ancient breadbasket stretching from the Middle East to India - as they vowed new action to isolate and interrupt the steady march of dangerous wheat rust diseases. http://www.physorg.com/news171865283.html Biology Fri, 11 Sep 2009 05:22:12 EST news171865283 At one time or another most of us wonder where we came from, where our parents or grandparents and their parents came from. Did our ancestors come from Europe or Asia? As curious as we are about our ancestors, for practical purposes, we need to think about the ancestry of our genes, according to Cecil Lewis, assistant professor of anthropology at the University of Oklahoma. Lewis says our genetic ancestry influences the genetic traits that predispose us to risk or resistance to disease. http://www.physorg.com/news169474130.html Biology Fri, 14 Aug 2009 13:09:49 EST news169474130 (PhysOrg.com) -- African village dogs are not a mixture of modern breeds but have directly descended from an ancestral pool of indigenous dogs, according to a Cornell-led genetic analysis of hundreds of semi-feral village dogs. http://www.physorg.com/news168619238.html Biology Tue, 04 Aug 2009 15:41:07 EST news168619238 The progressive degradation of useful soils for agriculture and farm animal husbandry is a growing environmental and social problem, given that it endangers the food safety of an increasing world population. This fact prompted the Basque Institute for Agricultural Research and Development - Neiker-Tecnalia - to design a series of research projects in order to evaluate alternative agricultural practices, as a function of their capacity to combine the productivity of crops with the health of the soil. http://www.physorg.com/news167657289.html Space & Earth Fri, 24 Jul 2009 12:28:38 EST news167657289 Rice is the world's most important food crop.

Fortunately, for all of us who do not relish the thought of spending our days searching for nuts and berries, early civilizations successfully cultivated many species of animals and plants found in their surroundings. Current studies of the domestication of various species provide a fascinating glimpse into the past. http://www.physorg.com/news164639448.html Biology Fri, 19 Jun 2009 14:11:27 EST news164639448 The health of our skin -- one of the body's first lines of defense against illness and injury - depends upon the delicate balance between our own cells and the millions of bacteria and other one-celled microbes that live on its surface. To better understand this balance, National Institutes of Health researchers have set out to explore the skin's microbiome, which is all of the DNA, or genomes, of all of the microbes that inhabit human skin. Their initial analysis, published today in the journal Science, reveals that our skin is home to a much wider array of bacteria than previously thought. http://www.physorg.com/news162740258.html Medicine & Health Thu, 28 May 2009 14:38:11 EST news162740258 Ethnicity is having a significant impact on timely access to cardiac care in Calgary and likely across Canada as the population's ethnic diversity grows, according to new research led by a team from the University of Calgary. http://www.physorg.com/news160754247.html Medicine & Health Tue, 05 May 2009 14:57:58 EST news160754247 The grey wolf was Monday taken off the US list of endangered species, making a comeback 35 years after it virtually disappeared and can now be hunted in most US states, officials said. http://www.physorg.com/news160675250.html Biology Mon, 04 May 2009 17:01:27 EST news160675250 Dinosaurs were dying out much earlier than the mass extinction event 65 million years ago, Natural History Museum scientists report in the Proceedings of the Royal Society journal today. http://www.physorg.com/news160324445.html Other Sciences Thu, 30 Apr 2009 15:34:45 EST news160324445 When grasslands are fertilized their productivity is increased but their plant diversity is diminished. In the last 50 years levels of plant-available nitrogen and phosphorous have doubled worldwide. This additional supply of plant nutrients is predicted to be one of the three most important causes of biodiversity loss this century. The research, under the leadership of Professor Andy Hector from the University of Zurich, shows for the first time the exact mechanisms that lead to the loss of biodiversity from grasslands following fertilization. http://www.physorg.com/news160320894.html Biology Thu, 30 Apr 2009 14:35:43 EST news160320894 African, American, and European researchers working in collaboration over a 10-year period have released the largest-ever study of African genetic data--more than four million genotypes--providing a library of new information on the continent which is thought to be the source of the oldest settlements of modern humans. http://www.physorg.com/news160319662.html Biology Thu, 30 Apr 2009 14:14:45 EST news160319662 The situation of bears in the Iberian Peninsula is critical.
