Aggressive African bees were accidentally released in Brazil in 1957. As "killer bees" spread northward, David Roubik, staff scientist at the Smithsonian Tropical Research Institute, began a 17-year study that revealed that Africanized bees caused less damage to native bees than changes in the weather and may have increased the availability of their food plants. http://www.physorg.com/news173628737.html Biology Thu, 01 Oct 2009 15:30:22 EST news173628737 (PhysOrg.com) -- Misidentifying boll weevils caught in pheromone traps could be easier to avoid, thanks to a new DNA fingerprinting method devised by Agricultural Research Service (ARS) scientists and their collaborators. http://www.physorg.com/news171790886.html Biology Thu, 10 Sep 2009 09:50:03 EST news171790886 (PhysOrg.com) -- When studying cold atoms, scientists often use magnetic or optical traps to keep the atoms in place. However, in some cases experimentalists want to study free atoms, avoiding the effects of a trap. "One way to study free atoms," Cass Sackett tells PhysOrg.com, "is by bouncing them off a surface... most of the time, the atoms are free." He says that scientists have been interested in bouncing atoms for a long time, but that before now only about five bounces have been achieved. "Using magnets and certain lasers, it is possible to bounce atoms. However, they are lost relatively quickly." http://www.physorg.com/news160053848.html Physics Mon, 27 Apr 2009 12:24:47 EST news160053848 Researchers at North Carolina State University have found an exponentially better way to protect streams and lakes from the muddy runoff associated with stormwater around road and other construction projects. http://www.physorg.com/news159190208.html Space & Earth Fri, 17 Apr 2009 12:30:50 EST news159190208 (PhysOrg.com) -- Physicists at the National Institute of Standards and Technology have demonstrated a new ion trap that enables ions to go through an intersection while keeping their cool. Ten million times cooler than in prior similar trips, in fact. The demonstration, described in a forthcoming paper in Physical Review Letters,* is a step toward scaling up trap technology to build a large-scale quantum computer using ions (electrically charged atoms), a potentially powerful machine that could perform certain calculations -such as breaking today`s best data encryption codes -much faster than today`s computers. http://www.physorg.com/news158417507.html Physics Wed, 08 Apr 2009 13:52:14 EST news158417507 (AP) -- Skip Ryan has worked the same channel into Boston Harbor for 50 years, setting and hauling his lobster traps so often that he is certain of one thing. http://www.physorg.com/news157052902.html Biology Mon, 23 Mar 2009 18:49:27 EST news157052902 (PhysOrg.com) -- New England lobstermen have gone high tech by adding low-cost instruments to their lobster pots that record bottom temperature and provide data that could help improve ocean circulation models in the Gulf of Maine. http://www.physorg.com/news155818404.html Space & Earth Mon, 09 Mar 2009 11:54:16 EST news155818404 Mosquito traps that reek like latrines may be no more. A University of California, Davis research team led by chemical ecologist Walter Leal has discovered a low-cost, easy-to-prepare attractant that lures blood-fed mosquitoes without making humans hold their noses. http://www.physorg.com/news139233149.html Biology Fri, 29 Aug 2008 12:52:29 EST news139233149
