Their study, outlined in a paper published in Physical Review Letters, suggests that training can enhance the performance of BP decoders significantly, helping to solve issues that are commonly associated with their application in quantum research. https://phys.org/news/2019-06-neural-belief-propagation-decoders-quantum-error-correcting.html Quantum Physics Tue, 04 Jun 2019 09:40:02 EDT news478858206 Researchers in Strasbourg, France, have found that mixing two small biomolecules, glyoxylate and pyruvate, in iron-salt-rich water produces a reaction network resembling life's core biochemistry. This discovery provides insight into how chemistry on the early Earth primed the evolution of the most ancient life. The study was published in the journal Nature.  https://phys.org/news/2019-05-life-biochemical-networks-spontaneously-earth.html Biochemistry Fri, 03 May 2019 07:20:22 EDT news476086806 Infrared spectroscopy is the benchmark method for detecting and analyzing organic compounds. But it requires complicated procedures and large, expensive instruments, making device miniaturization challenging and hindering its use for some industrial and medical applications and for data collection out in the field, such as for measuring pollutant concentrations. Furthermore, it is fundamentally limited by low sensitivities and therefore requires large sample amounts. https://phys.org/news/2018-06-nanotech-sensor-molecular-fingerprints-bar.html Materials Science Thu, 07 Jun 2018 14:00:08 EDT news447578434 (Phys.org)—Stanford engineers have designed and built a prism-like device that can split a beam of light into different colors and bend the light at right angles, a development that could eventually lead to computers that use optics, rather than electricity, to carry data. https://phys.org/news/2014-12-big-wires.html Optics & Photonics Wed, 03 Dec 2014 05:59:58 EST news336808791 Sharing on social media helps hackers sharpen "spear phishing" attacks they use to trick their way into computers, security experts said Monday. https://phys.org/news/2013-07-online-hackers-sharpen-spears.html Internet Mon, 29 Jul 2013 19:10:01 EDT news294343156 Fully autonomous cars may still be the stuff of science fiction. Remote driving technology, however, may be much closer than we think. Scientists at the Technische Universität München believe that full-size remote control cars could be hitting the roads within the next five to ten years. So if your next rental car turns up to your door driverless, the chances are that the actual driver is sitting in the car rental headquarters. https://phys.org/news/2013-07-visiom-e-mobility-unveils-remote-technology.html Engineering Mon, 29 Jul 2013 12:08:50 EDT news294318518 (Phys.org)—University of Alabama at Birmingham (UAB) researchers have developed simple but effective techniques to prevent sophisticated malware from secretly attacking smartphones. The Tap-Wave-Rub (TWR) methods – tapping, waving a hand over or rubbing the phone's proximity sensor – are being presented at the 6th Association for Computing Machinery Conference on Security and Privacy in Wireless and Mobile Networks (WiSec'13) April 17-19, 2013, in Hungary, Budapest. https://phys.org/news/2013-02-team-simple-defense-complex-smartphone.html Software Thu, 28 Feb 2013 17:41:57 EST news281295693 Software titan Microsoft and computer security giant Symantec said Thursday that they smashed a hacker-infected computer network that was hijacking Internet searches. https://phys.org/news/2013-02-hacker-botnet-hijacked-online.html Internet Thu, 07 Feb 2013 15:48:18 EST news279474464 (Phys.org)—A Palo Alto-based retail analytics company this week introduced a no-hardware solution for retailers seeking store traffic data on customers. The solution works simply by monitoring people's mobile devices. The company is Euclid and the new product is Euclid Zero, designed to pick up unique mobile device IDs on smartphones when they recognize a store's Wi-Fi network. Euclid Zero will give retailers, malls, and other venues the ability to measure in-store behavior. https://phys.org/news/2013-01-euclid-debuts-capture-in-store-shopper.html Business Sat, 12 Jan 2013 17:40:24 EST news277234788 In its early years, information theory — which grew out of a landmark 1948 paper by MIT alumnus and future professor Claude Shannon — was dominated by research on error-correcting codes: How do you encode information so as to guarantee its faithful transmission, even in the presence of the corrupting influences engineers call "noise"? https://phys.org/news/2012-05-elusive-capacity-networks.html Computer Sciences Tue, 15 May 2012 07:25:51 EDT news256285504 Microsoft on Monday said that cyber crime "command" servers in two US states were seized in an ongoing campaign to sever online crooks from infected computers used as virtual henchmen. https://phys.org/news/2012-03-hacker-servers-seized-microsoft.html Internet Mon, 26 Mar 2012 16:12:37 EDT news251997150 Network coding is an innovative new approach to network design that promises much more efficient use of bandwidth, and MIT researchers have made seminal contributions to its development.
