Just in time for World Space Week, NASA has released a new mobile application that challenges gamers to take on the role of a space communications network manager and puts them in charge of building a communications network to support scientific missions. http://phys.org/news268648372.html Space & Earth Fri, 05 Oct 2012 09:32:59 EST news268648372 (Phys.org)—A team of German physicists has successfully demonstrated an ability to perform quantum key distribution (QKD) exchange between an airplane in flight and a ground station, paving the way perhaps to the same kinds of communications between satellites and ground stations which could lead to a global quantum based secure communications network. The team presented their results at the QCrypt convention this past week. http://phys.org/news267167233.html Physics Tue, 18 Sep 2012 06:07:35 EST news267167233 Creation of a next-generation public safety communications network requires leadership from a single non-profit organization devoted to this purpose, according to a report released today by a federal advisory committee. Such a network would support voice, video and data transmissions, and ideally be at the disposal of all first responders—the medical, emergency, law enforcement or military personnel who are first on the scene of events that threaten public safety. http://phys.org/news247320565.html Technology Wed, 01 Feb 2012 12:09:34 EST news247320565 Engineering researchers at the University of Arkansas are developing an emergency communications network that will maintain operation during natural disasters and provide critical warnings and geographic information to people affected by the disasters. The researchers are honing and testing the system now and expect to deploy a pilot network at the end of 2012.  http://phys.org/news247316412.html Technology Wed, 01 Feb 2012 11:00:17 EST news247316412 (PhysOrg.com) -- Hackers at the Chaos Communication Congress in Berlin, which wrapped up over the weekend, are toasting the New Year with a newly announced plan for a hacker-owned satellite communications network. The anti-censorship allies want to counter the spate of legislative and government efforts that seek to interfere with Internet freedoms. http://phys.org/news244724873.html Technology Mon, 02 Jan 2012 11:09:32 EST news244724873 At a time when the Internet puts an untold amount of information at anyone’s fingertips, and automated scientific experiments churn out data faster than researchers can keep up with it, and communications networks can include billions of people, even the simplest computational tasks can become so enormous that they would overwhelm even a powerful supercomputer. But sometimes it’s enough to know just a little bit about the solution to a monstrous calculation: biologists mining genomic data, for instance, might be interested in just a handful of genes. http://phys.org/news220773681.html Technology Thu, 31 Mar 2011 07:03:10 EST news220773681 (AP) -- Paul Baran, whose work with packaging data in the 1960s has been credited with playing a role in the later development of the Internet, has died at age 84, his son said. http://phys.org/news220514015.html Technology Mon, 28 Mar 2011 06:53:57 EST news220514015 The maximum-flow problem, or max flow, is one of the most basic problems in computer science: First solved during preparations for the Berlin airlift, it’s a component of many logistical problems and a staple of introductory courses on algorithms. For decades it was a prominent research subject, with new algorithms that solved it more and more efficiently coming out once or twice a year. But as the problem became better understood, the pace of innovation slowed. Now, however, MIT researchers, together with colleagues at Yale and the University of Southern California, have demonstrated the first improvement of the max-flow algorithm in 10 years. http://phys.org/news204806137.html Technology Mon, 27 Sep 2010 11:36:23 EST news204806137 (AP) -- The government and Australia's largest telecommunications company announced a deal Sunday that clears a major hurdle to Prime Minister Kevin Rudd's plans for a superfast national broadband network. http://phys.org/news196222510.html Technology Sun, 20 Jun 2010 03:40:01 EST news196222510 With awiloc, the WLAN positioning technology, Fraunhofer researchers present new tools and an adaptable portfolio of services for building reference databases to be used throughout Europe. The technology will enable partners to realize localization solutions and services in cities and buildings. At the Mobile World Congress 2010, the experts show you how you can utilize awiloc on your own terminal devices for navigation, positioning or as a guidance system. http://phys.org/news185199449.html Technology Fri, 12 Feb 2010 12:40:01 EST news185199449 (PhysOrg.com) -- Similarities between webs of terrorists and networks of rescue personnel may seem unlikely. To an eclectic collaboration of engineers and social scientists, the connections are not only possible, but a potential source of deep insights. http://phys.org/news180371964.html Other Sciences Fri, 18 Dec 2009 15:30:02 EST news180371964 (PhysOrg.com) -- The huge increases in the power and capacity of computers, cell phones and communications networks in the last 40 years have been the result of ever-shrinking silicon transistors. But silicon transistors are now getting so small that they’re running up against fundamental physical limits: soon, it will be impossible to squeeze any better performance out of them. http://phys.org/news179518970.html Technology Tue, 08 Dec 2009 18:25:46 EST news179518970 (PhysOrg.com) -- For the first time ever, a modern dance company has performed to music generated from seismic data, recorded from four volcanoes across three continents. This unique event was facilitated by DANTE, the provider of high speed research and education networks, the two distributed computing projects, Enabling Grids for E-sciencE (EGEE) and E-science grid facility for Europe and Latin America (EELA), as well as CityDance Ensemble, a prestigious company based in Washington, DC. http://phys.org/news157308512.html Other Sciences Thu, 26 Mar 2009 17:49:14 EST news157308512
