New research finds sexual selection to greatly enlarge the scope for adaptive speciation by triggering a positive feedback between mate choice and ecological diversification that can eventually eliminate gene flow between species. http://www.physorg.com/news178458331.html Biology Thu, 26 Nov 2009 14:00:07 EST news178458331 (PhysOrg.com) -- A new generation of ultrasmall transistors and more powerful computer chips using tiny structures called semiconducting nanowires are closer to reality after a key discovery by researchers at IBM, Purdue University and the University of California at Los Angeles. http://www.physorg.com/news178459486.html Nanotechnology Thu, 26 Nov 2009 14:00:05 EST news178459486 (PhysOrg.com) -- The copper sequestering drug tetrathiomolybdate (TM) has been shown in studies to be effective in the treatment of Wilson disease, a disease caused by an overload of copper, and certain metastatic cancers.

These predatory mites then exterminate the spider mite population, thus acting as a type of 'bodyguard' for the plant. However, if the plant is simultaneously attacked by whiteflies, insects that are related to aphids, the plant becomes less attractive to the predatory mites and therefore more vulnerable to spider mites. http://www.physorg.com/news178451189.html Biology Thu, 26 Nov 2009 09:47:54 EST news178451189 (PhysOrg.com) -- It may be a long time before we see robots shooting pucks and making saves in professional hockey, but second-year mechanical engineering students at the University of Alberta put some pretty impressive players to the test as part of a creative design course. http://www.physorg.com/news178449090.html Technology Thu, 26 Nov 2009 09:40:02 EST news178449090 (PhysOrg.com) -- A flute playing robot unveiled by Waseda University last year has been joined by a robot saxophonist in a Classical music duet.
