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

World Wide Web Consortium abandons consensus, standardizes DRM with 58.4% support, EFF resigns / Boing Boing

https://boingboing.net/2017/09/18/antifeatures-for-all.html In July, the Director of the World Wide Web Consortium overruled dozens of members’ objections to publishing a DRM standard without a compromise to protect accessibility, security research, archiving, and competition. EFF appealed the decision, the first-ever appeal in W3C history. 58.4% of the group voted to go on with publication, and the W3C did so today. It

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

DIY optical power meter with SFP module and Arduino idea

Fifer optics power meter is an important tool for debugging fiber optics networks. I have earlier tested a cheap commercial fiber optic power meter a at Fiber optics power meter posting. Hardware hackers ares famous for building their own test equipment. The basic operation of optical power meter is quite simple: take a suitable detector,
