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

Homeopathic remedies are ‘nonsense and risk significant harm’ say 29 European scientific bodies | The Independent

http://www.independent.co.uk/news/uk/home-news/homeopathy-nonsense-risk-harm-29-european-academies-science-advisory-council-remedies-a7963786.html A scientific organisation intended to influence EU policy has called for tougher regulations of alternative medicine, branding homeopathy“nonsense” and warning the “promotion and use of homeopathic products risks significant harms”. The statement was made by the European Academies Science Advisory Council (EASAC). Homeopathy uses vastly diluted amounts of a substance that causes symptoms in the hope of curing a

Turning up the heat on electrons reveals an elusive physics phenomenon | Science News

https://www.sciencenews.org/article/turning-heat-electrons-reveals-elusive-physics-phenomenon Electrons in platinum move in different directions depending on their spin when the metal is heated at one end. Scientists have observed this phenomenon, called the spin Nernst effect, for the first time. “The measurement was a tour de force; the measurement was ridiculously hard”  The effect and its brethren — with names like the

Scientists Connect A Human Brain To The Internet For The First Time | IFLScience

http://www.iflscience.com/brain/scientists-connect-human-brain-internet-first-time/ According to a press release, the team of neuroscientists and engineers have used an electroencephalogram (EEG) – a device that detects electrical signals in the brain – to transmit neurological activity to a cheap Raspberry Pi computer. This then live streams the data to a program running on a website that anyone can view at any time.

Scientists Have Managed To Store Light As Sound For The First Time | IFLScience

http://www.iflscience.com/technology/scientists-have-managed-to-store-light-as-sound-for-the-first-time/ A team of researchers from the University of Sydney has managed to convert the digital information carried by light waves into sound waves inside a microchip. As reported in Nature Communications, the researchers were able to build a chip that slows down light by turning it into sound waves. “The information in our chip in acoustic

Plastic-Eating Fungus Found At A Landfill Site In Pakistan | IFLScience

http://www.iflscience.com/plants-and-animals/plasticeating-fungus-found-at-a-landfill-site-in-pakistan/ Researchers have found a species of fungus, known as Aspergillus tubingensis, that is able to feed off of plastic. In lab experiments, published in Environmental Pollution, scientists found that the mycelium of the fungus colonizes polyester polyurethane plastic, causing surface degradation and scarring. This is not the first time that organisms have been found to be able to feed
