(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 Brown University researchers have discovered that Candida albicans, a human fungal pathogen that causes thrush and other diseases, pursues same-sex mating in addition to conventional opposite-sex mating. http://www.physorg.com/news169312643.html Biology Wed, 12 Aug 2009 17:10:02 EST news169312643 Orchids are famous for their deceptions. Most of those with nothing of value to offer their pollinators lure them instead with the scents of more rewarding flowers or potential mates. Now, a report published online on August 6th in Current Biology reveals for the first time that a species of orchid, which lives on the Chinese island of Hainan, fools its hornet pollinator by issuing a chemical that honeybees use to send an alarm. http://www.physorg.com/news168791912.html Biology Thu, 06 Aug 2009 16:00:01 EST news168791912 Scientists here have determined that combining bed bugs' own chemical signals with a common insect control agent makes that treatment more effective at killing the bugs. http://www.physorg.com/news163165086.html Biology Tue, 02 Jun 2009 12:38:39 EST news163165086 A new study published online on May 7th in Current Biology, a Cell Press publication, has found the source of silkworms' attraction to mulberry leaves, their primary food source. A jasmine-scented chemical emitted in small quantities by the leaves triggers a single, highly tuned olfactory receptor in the silkworms' antennae, they show. http://www.physorg.com/news160921154.html Biology Thu, 07 May 2009 13:20:44 EST news160921154 (PhysOrg.com) -- Ants colonize. Fish shoal. Flamingos flock and caribou herd. Earth is populated by inherently social beings. Even lowly worms seek out the benefits of companionship. New research at The Rockefeller University has dissected the social proclivities of a model worm, identifying a single type of neuron - RMG - that `decides` whether these worms will mingle with their fellows or keep to themselves. http://www.physorg.com/news158593386.html Medicine & Health Fri, 10 Apr 2009 14:43:47 EST news158593386 A synthetic chemical version of what male sea lampreys use to attract spawning females can lure them into traps and foil the mating process of the destructive invasive species, according to Michigan State University scientists. http://www.physorg.com/news151761214.html Chemistry Wed, 21 Jan 2009 11:53:59 EST news151761214 Bumblebees use flower scent to guide their nest-mates to good food sources, according to scientists from Queen Mary, University of London. http://www.physorg.com/news144069782.html Biology Fri, 24 Oct 2008 12:23:02 EST news144069782 Bumblebees choose whether to search for food according to how stocked their nests are, say scientists from Queen Mary, University of London. http://www.physorg.com/news137852687.html Biology Wed, 13 Aug 2008 13:24:47 EST news137852687 (PhysOrg.com) -- People will pay big bucks for pills that promise to enhance sex or slow aging. Now, a Cornell researcher and colleagues have uncovered a class of small molecules in tiny worms that not only attract mates but also arrest development for months in larvae. http://www.physorg.com/news137340149.html Biology Thu, 07 Aug 2008 15:02:29 EST news137340149 No scent. No sex. If a male Japanese beetle is unable to detect the sex pheromone released by a female, he won't be able to locate her and reproduce. http://www.physorg.com/news134040854.html Biology Mon, 30 Jun 2008 10:34:14 EST news134040854 Researchers at UT Southwestern Medical Center have overturned the current theory of how a pheromone works at the molecular level to trigger behavior in fruit flies. http://www.physorg.com/news133701890.html Medicine & Health Thu, 26 Jun 2008 12:24:50 EST news133701890
