(PhysOrg.com) -- Scientists at the U.S. Department of Energy`s Brookhaven National Laboratory have found a new way to use a synthetic form of DNA to control the assembly of nanoparticles - this time resulting in switchable, three-dimensional and small-cluster structures that might be useful, for example, as biosensors, in solar cells, and as new materials for data storage. The work is described in Nature Nanotechnology, published online December 20, 2009. http://www.physorg.com/news180624054.html Nanotechnology Mon, 21 Dec 2009 13:21:26 EST news180624054 The field of artificial-intelligence research (AI), founded more than 50 years ago, seems to many researchers to have spent much of that time wandering in the wilderness, swapping hugely ambitious goals for a relatively modest set of actual accomplishments. Now, some of the pioneers of the field, joined by later generations of thinkers, are gearing up for a massive 'do-over' of the whole idea. http://www.physorg.com/news179400180.html Technology Mon, 07 Dec 2009 09:23:41 EST news179400180 The Casimir force, also known as the Casimir effect, is typified by the small attractive force that acts between two close parallel uncharged conducting plates. Today, this force has become an interdisciplinary subject of study, playing an important role in condensed matter physics, quantum field theory, atomic and molecular physics, gravitation and cosmology, and mathematical physics. Most recently the Casimir force has been applied to nanotechnology. http://www.physorg.com/news168796398.html Physics Thu, 06 Aug 2009 17:10:01 EST news168796398 NComputing is out to span the digital divide with a version of cloud computing called "virtualization," which essentially turns one machine into many. http://www.physorg.com/news168768348.html Technology Thu, 06 Aug 2009 09:06:16 EST news168768348 Emeralds, rubies and the like are referred to as colored gemstones by experts.

New simulation results were needed for presentation at the Quark Matter physics conference; but all the computational resources were either committed to other tasks or did not support the environment needed for STAR computations. Fortunately, working with technology developed by the Nimbus team at the U.S. Department of Energy's (DOE) Argonne National Laboratory, the STAR researchers were able to dynamically provision virtual clusters on commercial cloud computers and run the additional computations just in time. http://www.physorg.com/news157974755.html Technology Fri, 03 Apr 2009 10:55:03 EST news157974755 (PhysOrg.com) -- The conficker worm created havoc last year when it infected over 10 million computers on a global scale.
