(PhysOrg.com) -- A common type of chronic diarrhoea may be caused by a hormone deficiency, according to new research published in the November issue of Clinical Gastroenterology and Hepatology. The authors of the paper, from Imperial College London, with collaborators from King's College London and the University of Edinburgh, say their results could help more doctors recognise this type of diarrhoeal illness, and may lead to the development of more effective tests and treatments to help improve the lives of many people suffering with chronic diarrhoea. http://www.physorg.com/news176387797.html Medicine & Health Mon, 02 Nov 2009 13:10:03 EST news176387797 Nanotubes, the tiny honeycomb cylinders of carbon atoms only a few nanometers wide, are perhaps the signature material of modern engineering research, but actually trying to organize the atomic scale rods is notoriously like herding cats. A new study* from the National Institute of Standards and Technology and Rice University, however, offers an inexpensive process that gets nanotubes to obediently line themselves up -- that is, self-assemble -- in neat rows, more like ducks. http://www.physorg.com/news151090330.html Nanotechnology Tue, 13 Jan 2009 17:32:10 EST news151090330
