MRAM-like Device Could Make Logic Run Backwards

https://spectrum.ieee.org/nanoclast/semiconductors/devices/mramlike-device-could-make-logic-run-backwards This is an interesting idea: Engineers at Purdue University and the University of California at Berkeley have discovered that a simple combination of commonly available devices creates a computing element that could lead to some truly strange circuits: logic that can perform its inverse operation. Some important aspects of modern computing—notably encryption—depend on there being

Sugar Industry Buried Evidence Of Links To Cancer And Heart Disease For Half A Century | IFLScience

http://www.iflscience.com/health-and-medicine/sugar-industry-buried-evidence-links-cancer-heart-disease-half-century/all/ The US government has only recently updated its health guidelines to advise people to cut out a lot of sugar from their diets, but as highlighted in two recent studies, the sugar industry has been aware of its dangers for at least half a century. It’s worth remembering that plenty of industry research is

Nanodevice Maps the Angle of Light to Color and Vice Versa – IEEE Spectrum

https://spectrum.ieee.org/nanoclast/semiconductors/nanotechnology/nanodevice-maps-the-angle-of-light-to-color-and-vice-versa  An international team of researchers has added a small twist to typical light filters. They’ve fabricated a nanoscale device that divides incident light into its different component colors based on the direction the light is coming from. They’ve switched from making filters with equally spaced grooves to an aperiodic architecture wherein the grooves are not equally spaced. The research

New Laser Technique Promises Photonic Devices Inside of Silicon – IEEE Spectrum

https://spectrum.ieee.org/nanoclast/semiconductors/optoelectronics/new-laser-technique-promises-photonic-devices-inside-of-silicon When a laser beam modifies a material, those modifications can either be temporary or permanent, and the change can also be either extremely subtle or drastic. The modified material starts responding differently to the laser beam. Scientists have taken advantage of these interactions to create structures within silicon that enable photonic devices. “We can also imagine

Physicists Will Be Announcing An “Unprecedented Discovery” On Monday – Here’s How To Watch Live | IFLScience

http://www.iflscience.com/space/a-huge-new-gravitational-waves-announcement-is-happening-on-monday/  In the space of just a few weeks, the LIGO and VIRGO collaborations have announced the fourth detection of gravitational waves and three of their most prominent physicists received a Nobel Prize for their work. And on Monday they will announce something new. 

Going to a sauna twice a week cuts pneumonia risk, study finds

http://www.telegraph.co.uk/science/2017/10/09/saunas-cut-pneumonia-risk/ Sauna is good for you in many ways has been known in Finland for a long time. Here is another proof:  Sweating in a sauna at least twice a week could slash the risk of potentially deadly infections like pneumonia, research shows. Men who enjoyed sauna sessions on a regular basis were almost 30 per cent less likely to develop the

Nobel Prize Awarded for Detection of Gravity Waves – IEEE Spectrum

https://spectrum.ieee.org/tech-talk/aerospace/astrophysics/nobel-prize-awarded-for-detection-of-gravity-waves  The three men who won this year’s Nobel Prize in physics helped prove Einstein correct by detecting gravitational waves from a pair of colliding black holes.  Rainer Weiss, Barry C. Barish and Kip S. Thorne were awarded for conceiving and creating the Laser Interferometer Gravitational Wave Observatory, or LIGO.  Just last week, a sister detector in Italy called Virgo
