(PhysOrg.com) -- Antennas aren't just for listening to the radio anymore. They're used in everything from cell phones to GPS devices. Research from North Carolina State University is revolutionizing the field of antenna design - creating shape-shifting antennas that open the door to a host of new uses in fields ranging from public safety to military deployment. http://www.physorg.com/news178897908.html Technology Tue, 01 Dec 2009 13:52:19 EST news178897908 (PhysOrg.com) -- NASA mission managers are assessing options for future operations of the venerable QuikScat satellite following the age-related failure of a mechanism that spins the scatterometer antenna. This spinning antenna had been providing near-real-time ocean- surface wind speed and direction data over 90 percent of the global ocean every day. http://www.physorg.com/news178304391.html Space & Earth Tue, 24 Nov 2009 17:40:02 EST news178304391 (PhysOrg.com) -- Engineering researchers at the University of Arkansas have developed a unique and robust method to prevent cloning of passive radio frequency identification tags. The technology, based on one or more unique physical attributes of individual tags rather than information stored on them, will prevent the production of counterfeit tags and thus greatly enhance both security and privacy for government agencies, businesses and consumers. http://www.physorg.com/news177842859.html Technology Thu, 19 Nov 2009 08:48:17 EST news177842859 She's gone. We were the best of friends, constant companions -- literally, because I carried her day and night in the left-front pocket of my jeans. For five years we roamed the world together, or at least the United States, since she wasn't GSM-compatible. http://www.physorg.com/news177788246.html Electronics Wed, 18 Nov 2009 18:40:01 EST news177788246 More than 120 years after the discovery of the electromagnetic character of radio waves by Heinrich Hertz, wireless data transmission dominates information technology. Higher and higher radio frequencies are applied to transmit more data within shorter periods of time. Some years ago, scientists found that light waves might also be used for radio transmis-sion. So far, however, manufacture of the small antennas has required an enormous expenditure. German scientists have now succeeded for the first time in specifically and reproducibly manufacturing smallest optical nanoantennas from gold. http://www.physorg.com/news175262415.html Nanotechnology Tue, 20 Oct 2009 13:10:01 EST news175262415 Since Apple Inc. announced it would support turn-by-turn GPS applications for the iPhone, a slew of GPS apps have appeared in the iTunes app store. http://www.physorg.com/news174207254.html Technology Thu, 08 Oct 2009 14:00:01 EST news174207254 (PhysOrg.com) -- With a simple press on his shirt insignia, the captain of the Star Ship Enterprise could send and receive messages.

The 40-foot-diameter antenna, weighing about 100 tons, was moved to ALMA's high-altitude Array Operations Site, where the extremely dry and rarefied air is ideal for observing the Universe. http://www.physorg.com/news172925187.html Space & Earth Wed, 23 Sep 2009 12:20:01 EST news172925187 Antennas for the latest implanted medical devices are being developed by Queen Mary University of London and tested through a unique piece of kit at the UK's National Physical Laboratory (NPL). http://www.physorg.com/news171620414.html Technology Tue, 08 Sep 2009 09:30:01 EST news171620414 Anyone who's vacationed in the mountains or lived on a farm knows that it's hard to get good internet access or a strong cell phone signal in a remote area. Communicating across great distances has always been a challenge. So when NASA engineers designed the Lunar Reconnaissance Orbiter (LRO), they knew it would need an extraordinary communications system. http://www.physorg.com/news169912309.html Space & Earth Wed, 19 Aug 2009 15:30:03 EST news169912309 (PhysOrg.com) -- Large numbers of bats are killed by colliding with turbine blades or by experiencing sudden depressurisation immediately adjacent to the blade. http://www.physorg.com/news166978013.html Biology Thu, 16 Jul 2009 15:47:36 EST news166978013 It seemed so simple.
