(PhysOrg.com) -- Colonies of social insects such as ants and bees could collectively make decisions using mechanisms similar to those used in primate brains, according to new research from the University of Bristol. http://www.physorg.com/news154795756.html Biology Wed, 25 Feb 2009 14:50:36 EST news154795756 (PhysOrg.com) -- A study of natural pest control on conventional and organic farms in the southwest has found no difference between the two systems. http://www.physorg.com/news152895747.html Biology Tue, 03 Feb 2009 15:02:49 EST news152895747 New data, published today, disproves the recent theory that a large comet exploded over North America 12,900 years ago, causing a shock wave that travelled across North America at hundreds of kilometres per hour and triggering continent-wide wildfires. http://www.physorg.com/news152212774.html Space & Earth Mon, 26 Jan 2009 17:20:22 EST news152212774 (PhysOrg.com) -- Exciting research into blood clotting by British Heart Foundation (BHF) researchers working at the University of Bristol will take us a step closer to better heart attack prevention and treatment. Blood clots can be both life-saving and life-threatening; life-saving when they stop bleeding, but life-threatening when they form in diseased arteries feeding the heart. Here they can cause a heart attack, and do so in 146,000 people in the UK every year. http://www.physorg.com/news151679743.html Medicine & Health Tue, 20 Jan 2009 13:16:09 EST news151679743 (PhysOrg.com) -- By carefully selecting which varieties of food crops to cultivate, much of Europe and North America could be cooled by up to 1°C during the summer growing season, say researchers from the University of Bristol, UK. This is equivalent to an annual global cooling of over 0.1°C, almost 20% of the total global temperature increase since the Industrial Revolution. http://www.physorg.com/news151243486.html Biology Thu, 15 Jan 2009 12:04:46 EST news151243486 (PhysOrg.com) -- The fossil record is known to be biased by the unevenness of geographical and stratigraphical sampling, and the lack of exposed rocks containing fossils. In a recent Perspective in Science [2 January 2009] Professor Chris Hawkesworth from the University of Bristol and colleagues suggest that a similar unevenness biases the record of the evolution of the continental crust. http://www.physorg.com/news151164927.html Space & Earth Wed, 14 Jan 2009 14:15:27 EST news151164927 (PhysOrg.com) -- Plants and their pollinators are the focus of ground-breaking research by Dr Heather Whitney, recently appointed Lloyds Fellow in the School of Biological Sciences. Her latest work, carried out at the University of Cambridge and published this month in Science, showed for the first time that bees see some flowers in multi-colour because of previously unknown iridescence of the petals. http://www.physorg.com/news150727129.html Biology Fri, 09 Jan 2009 12:38:49 EST news150727129
