Exposure to light and possibly photosynthesis itself could be helping disease-causing bacteria to be internalized by lettuce leaves, making them impervious to washing, according to research published in the October issue of the journal Applied and Environmental Microbiology. http://www.physorg.com/news173369531.html Biology Mon, 28 Sep 2009 15:30:02 EST news173369531 Researchers Antonio G. Pisabarro (Professor of Microbiology) as well as José Luis Lavín and José Antonio Oguiza, from the Genetic and Microbiology Group at the Public University of Navarre, have taken part in the international project for the sequencing of the genome of the Postia placenta fungus. The results, published recently in the American National Academy of Sciences' scientific journal (PNAS), has enabled the determination of the mechanisms with which this fungus attacks wood in order to use the cellulose contained within. These results are important for designing processes using wood to produce bioethanol. http://www.physorg.com/news154958548.html Biology Fri, 27 Feb 2009 12:02:55 EST news154958548 Recently, the U.S. Department of Energy awarded Montana State University and Utah State University a three-year, $900,000 grant to study the oil produced by algae, which could be a renewable source of biodiesel. http://www.physorg.com/news145801168.html Chemistry Thu, 13 Nov 2008 12:19:28 EST news145801168 If the biofuel known as bioethanol is to make a major contribution to our fuel supplies, then we may well require the assistance of some tiny insect helpers, says Michael Scharf, an assistant professor of entomology at the University of Florida, Gainesville. http://www.physorg.com/news143866897.html Biology Wed, 22 Oct 2008 04:01:37 EST news143866897 (PhysOrg.com) -- When a newly developed technology for producing hydrogen gas from biowaste is brought to commercial use - as researchers believe it can be - then it appears the world will have plenty of energy if it can just solve the stubborn shortage of sewage. http://www.physorg.com/news142702016.html Technology Wed, 08 Oct 2008 16:26:56 EST news142702016 Widespread reports had most people afraid to eat tomatoes this summer and when tomatoes were vindicated, eating peppers became a fear. A University of Missouri food safety expert says there is only so much that can be done to assure produce is safe to eat. http://www.physorg.com/news141316825.html Medicine & Health Mon, 22 Sep 2008 15:40:25 EST news141316825 A North Carolina State University engineer has been awarded a $1.6 million grant from the U.S. Department of Energy to learn more about the microbiology, genetics and genomics behind how and why heat-loving bacteria called thermotogales produce large amounts of hydrogen with unusually high efficiencies. These microorganisms are found all over the globe in areas which are naturally hot - including volcanic sediments, hot springs and brines from deep oil wells. http://www.physorg.com/news136653203.html Biology Wed, 30 Jul 2008 16:13:23 EST news136653203 Researchers have combined the efforts of two kinds of bacteria to produce hydrogen in a bioreactor, with the product from one providing food for the other. According to an article in the August issue of Microbiology Today, this technology has an added bonus: leftover enzymes can be used to scavenge precious metals from spent automotive catalysts to help make fuel cells that convert hydrogen into energy. http://www.physorg.com/news135482832.html Biology Thu, 17 Jul 2008 03:07:12 EST news135482832 A greener, less expensive method to produce hydrogen for fuel may eventually be possible with the help of water, solar energy and nanotube diodes that use the entire spectrum of the sun's energy, according to Penn State researchers. http://www.physorg.com/news135349137.html Nanotechnology Tue, 15 Jul 2008 13:58:57 EST news135349137
