(Phys.org) -- A team of EPFL scientists has developed an algorithm that can identify the source of an epidemic or information circulating within a network, a method that could also be used to help with criminal investigations. http://phys.org/news263817379.html Other Sciences Fri, 10 Aug 2012 12:00:02 EST news263817379 In the growth of crystals, do nanoparticles act as "artificial atoms" forming molecular-type building blocks that can assemble into complex structures? This is the contention of a major but controversial theory to explain nanocrystal growth. A study by researchers at the DOE's Lawrence Berkeley National Laboratory (Berkeley Lab) may resolve the controversy and point the way to energy devices of the future. http://phys.org/news257078986.html Nanotechnology Thu, 24 May 2012 14:00:16 EST news257078986 Last summer, physicist Suzanne Amador Kane at Haverford College in Pennsylvania set up an experiment looking at how flocks of small birds on her campus -- swallows -- defend themselves from predators by ganging up and forming mobs. http://phys.org/news192206159.html Biology Tue, 04 May 2010 15:36:37 EST news192206159
