Thanks to a new development by researchers at the National Institute of Standards and Technology and five partners, you can add one more application to the list: detection and destruction of an aggressive form of breast cancer. http://www.physorg.com/news178982129.html Medicine & Health Wed, 02 Dec 2009 15:20:01 EST news178982129 Novel nanomaterials developed at Rensselaer were sent into orbit on Nov. 16 aboard Space Shuttle Atlantis. http://www.physorg.com/news178304620.html Nanotechnology Tue, 24 Nov 2009 17:04:10 EST news178304620 (PhysOrg.com) -- "Carbon nanotubes are exciting for fundamental physics, and for potential technological applications," Nadya Mason tells PhysOrg.com. "However, we are generally limited in the way that we can study them. Many of these limitations have to do with controlling tunneling, or the way electrons move on and off the nanotube." In order to overcome this limitation, Mason, a scientist at the University of Illinois at Urbana-Champaign, participated in an experiment using a superconducting tunnel probe in a carbon nanotube to observe spectroscopic features. http://www.physorg.com/news177934374.html Nanotechnology Fri, 20 Nov 2009 10:13:55 EST news177934374 (PhysOrg.com) -- Most people would like to be able to charge their cell phones and other personal electronics quickly and not too often.

Now, a different team of scientists has built a loudspeaker made of tiny aluminum wires suspended like a bridge between two supports, producing sound in a similar way. The new wire bridge also has the advantage of being much easier to fabricate than the nanotube device, offering the potential for a wide range of audio applications. http://www.physorg.com/news176543078.html Physics Wed, 04 Nov 2009 09:00:01 EST news176543078 (PhysOrg.com) -- Rice University scientists today unveiled a method for the industrial-scale processing of pure carbon-nanotube fibers that could lead to revolutionary advances in materials science, power distribution and nanoelectronics. The result of a nine-year program, the method builds upon tried-and-true processes that chemical firms have used for decades to produce plastics. The research is available online in the journal Nature Nanotechnology. http://www.physorg.com/news176396559.html Nanotechnology Mon, 02 Nov 2009 15:04:34 EST news176396559 (PhysOrg.com) -- The ability to store and retrieve data is an important component of today's computers, as well as other modern electronic devices such as cell phones, video game consoles, and camcorders. Since their invention in the 1950s, magnetic-based hard disk drives (HDDs) have been the primary method of nonvolatile storage.
