(Phys.org)—Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today's electricity expenses, according to new research by the University of Delaware and Delaware Technical Community College. http://phys.org/news274367809.html Technology Mon, 10 Dec 2012 13:17:20 EST news274367809 The real-time data of cyberspace, detailing every like, dislike, spur of the moment thought—and more—provide unprecedented opportunities for research by scientists from all areas. http://phys.org/news267800430.html Technology Tue, 25 Sep 2012 14:01:25 EST news267800430 (Phys.org)—UT Dallas computer scientists have developed a technique to automatically allow one computer in a virtual network to monitor another for intrusions, viruses or anything else that could cause a computer to malfunction. http://phys.org/news267266671.html Technology Wed, 19 Sep 2012 09:44:40 EST news267266671 Do you have what it takes to be an ethical hacker? Can you step into the shoes of a professional paid to outsmart supposedly locked-down systems? Now you can at least try, no matter what your background, with a new card game developed by University of Washington computer scientists. http://phys.org/news262366343.html Technology Tue, 24 Jul 2012 16:32:36 EST news262366343 The chances of our planet being hit by a global warming of 3 degrees Celsius by 2050 is as likely as it being hit by an increase of 1.4 degrees, new research shows. Presented in the journal Nature Geoscience, the British study ran close to 10 000 climate simulations on home computers via a sophisticated climate model to get the results, which suggest that failure to stop emissions will force Earth to cross the two-degree barrier before this century ends. http://phys.org/news256889225.html Space & Earth Tue, 22 May 2012 07:07:21 EST news256889225 Your typing style is as individual as your fingerprints.

But where the earliest ideas might have been conveyed in something as simple as a cave painting, modern-day scientists are wrestling with phenomena as big and complicated as intercontinental air pollution, desertification and global warming. http://phys.org/news248790039.html Other Sciences Sat, 18 Feb 2012 13:00:03 EST news248790039 Intersections of the future will not need stop lights or stop signs, but will look like a somewhat chaotic flow of driverless, autonomous cars slipping past one another as they are managed by a virtual traffic controller, says computer scientist Peter Stone. http://phys.org/news248789776.html Technology Sat, 18 Feb 2012 12:40:01 EST news248789776 Saturn's largest moon, Titan, is an intriguing, alien world that's covered in a thick atmosphere with abundant methane. With an average surface temperature of a brisk -297 degrees Fahrenheit (about 90 kelvins) and a diameter just less than half of Earth's, Titan boasts methane clouds and fog, as well as rainstorms and plentiful lakes of liquid methane. It's the only place in the solar system, other than Earth, that has large bodies of liquid on its surface. http://phys.org/news244897912.html Space & Earth Wed, 04 Jan 2012 13:00:01 EST news244897912 Light-emitting diodes (LEDs) are an increasingly popular technology for use in energy-efficient lighting. Researchers from North Carolina State University have now developed a new technique that reduces defects in the gallium nitride (GaN) films used to create LEDs, making them more efficient. http://phys.org/news215183256.html Physics Tue, 25 Jan 2011 13:09:53 EST news215183256 Having a computer that can read our emotions could lead to all sorts of new applications, including computer games where the player has to control their emotions while playing. Thomas Christy, a Computer Science PhD student at Bangor University is hoping to bring this reality a little nearer by developing a system that will enable computers to read and interpret our emotions and moods in real time. http://phys.org/news214751728.html Technology Thu, 20 Jan 2011 13:16:21 EST news214751728 (PhysOrg.com) -- Physicists at Ohio State University have discovered that tiny defects inside a computer chip can be used to tune the properties of key atoms in the chip. http://phys.org/news211127786.html Physics Thu, 09 Dec 2010 14:36:55 EST news211127786 Barbie has become a computer engineer, with pink sensible shoes and a pink laptop. One of the most-watched sitcoms on network TV tells the story of three physicists and one engineer working at an institution that resembles Caltech in Pasadena.

But now, Cornell researchers offer a way to build security into computer systems from the start, by incorporating security in the language used to write the programs. http://phys.org/news205140710.html Technology Fri, 01 Oct 2010 08:32:15 EST news205140710 A new study indicates that methane in the atmosphere of Mars lasts less than a year. Methane is replenished from localized sources that show seasonal and annual variations. This pattern of methane production raises questions as to whether the methane comes from geological activity - or biological processes. http://phys.org/news204286796.html Space & Earth Tue, 21 Sep 2010 11:20:12 EST news204286796 In the 1950s and '60s, artificial-intelligence researchers saw themselves as trying to uncover the rules of thought. But those rules turned out to be way more complicated than anyone had imagined. Since then, artificial-intelligence (AI) research has come to rely, instead, on probabilities -- statistical patterns that computers can learn from large sets of training data. http://phys.org/news189178495.html Technology Tue, 30 Mar 2010 14:35:23 EST news189178495 (PhysOrg.com) -- A new generation of ultrasmall transistors and more powerful computer chips using tiny structures called semiconducting nanowires are closer to reality after a key discovery by researchers at IBM, Purdue University and the University of California at Los Angeles. http://phys.org/news178459486.html Nanotechnology Thu, 26 Nov 2009 14:00:05 EST news178459486 A multidisciplinary team led by Carnegie Mellon University computer scientist Edmund M.

These arc volcanoes, which account for about 10 to 25 percent of all volcanoes, are produced when one of the plates that make up Earth’s crust plunges beneath another plate, a process called subduction. http://phys.org/news163684334.html Space & Earth Mon, 08 Jun 2009 12:54:21 EST news163684334 US astronauts on Sunday will undertake a fourth in a series of five daily spacewalks intended to equip the 19-year-old Hubble Space Telescope for at least another five years of valuable scientific work. http://phys.org/news161749636.html Space & Earth Sun, 17 May 2009 03:29:38 EST news161749636 Science and engineering are advancing rapidly in part due to ever more powerful computer simulations, yet the most advanced supercomputers require programming skills that all too few U.S. researchers possess. At the same time, affordable computers and committed national programs outside the U.S. are eroding American competitiveness in number of simulation-driven fields. http://phys.org/news160411089.html Technology Fri, 01 May 2009 15:38:32 EST news160411089 DNA sequencing is the next frontier in biological research.
