How does evolution innovate? We exist because our ancestors have had the ability to adapt successfully to changes in their environment; however, merely examining present-day organisms can limit our understanding of the actual evolutionary processes because the crucial events have been masked by the passage of aeons – what we need is a time machine. Scientists from VIB, KU Leuven, University of Ghent and Harvard have done the next-best thing; by reconstructing DNA and proteins from prehistoric yeast cells, they were able to directly examine the evolutionary forces that have acted over the last 100 million years to shape modern-day enzymes – biological catalysts that enable organisms to manipulate molecules to their will. http://phys.org/news274465289.html Biology Tue, 11 Dec 2012 17:00:17 EST news274465289 This week it became official: the Titan supercomputer at Oak Ridge National Laboratory in Tennessee was crowned  the fastest computer on Earth, according to the Top500 list released this week that tracks these systems. http://phys.org/news272708634.html Electronics Wed, 21 Nov 2012 08:24:02 EST news272708634 Researchers at Carnegie Mellon University's Robotics Institute, working with colleagues at Google and the U.S. Geological Survey (USGS), have adapted their technology for interactively exploring time-lapse imagery to create a tool that enables anyone to easily access 13 years of NASA Landsat images of the Earth's surface. http://phys.org/news262870422.html Technology Mon, 30 Jul 2012 12:34:04 EST news262870422 The DeLorean - yes, that DeLorean - is back. http://phys.org/news238768488.html Technology Tue, 25 Oct 2011 14:00:01 EST news238768488 (AP) -- Good news for those who thought their copies of Playboy were gone forever when their moms found them and threw them away. http://phys.org/news225034154.html Technology Thu, 19 May 2011 14:29:22 EST news225034154 Researchers at Carnegie Mellon University's Robotics Institute have leveraged the latest browser technology to create GigaPan Time Machine, a system that enables viewers to explore gigapixel-scale, high-resolution videos and image sequences by panning or zooming in and out of the images while simultaneously moving back and forth through time. http://phys.org/news222614595.html Technology Thu, 21 Apr 2011 14:23:31 EST news222614595 (PhysOrg.com) -- If the latest theory of Tom Weiler and Chui Man Ho is right, the Large Hadron Collider – the world's largest atom smasher that started regular operation last year – could be the first machine capable causing matter to travel backwards in time. http://phys.org/news219425928.html Physics Tue, 15 Mar 2011 16:40:01 EST news219425928 (PhysOrg.com) -- Generally, scientists prefer to avoid the concept of perpetual motion. The idea of a machine that could produce movement that goes on forever, and using that movement to generate an endless stream of energy, is usually considered more science fiction than science. But recently, physicist Pavel Ivanov has investigated previous speculation that an exotic fluid with unusual properties could cause energy to flow continuously between different regions of space, resulting in a runaway transfer of energy. If an advanced civilization were able to construct a device to capture this energy, it might finally possess its own "perpetuum mobile" -- or perpetual motion. http://phys.org/news172225206.html Physics Tue, 15 Sep 2009 09:50:02 EST news172225206 With a brilliant idea and equations based on Einstein’s relativity theories, Ronald Mallett from the University of Connecticut has devised an experiment to observe a time traveling neutron in a circulating light beam. While his team still needs funding for the project, Mallett calculates that the possibility of time travel using this method could be verified within a decade. http://phys.org/news63371210.html Physics Tue, 04 Apr 2006 12:06:50 EST news63371210
