A nonprofit team is using open-source HF #radios to transfer encrypted files between remote communities and the rest of the world without relying on satellites or terrestrial networks. buff.ly/mzn4GJv

“It's our estimate that there's 50,000 gigawatt hours of energy wasted by utility-scale solar every year” https://spectrum.ieee.org/data-center-excess-solar?share_id=10074003

There’s a new way to produce #hydrogen, used as a clean #energy source in transportation, fuel cells, and space exploration. Using an electric pulse deep underground, engineers can crack rocks and capture hydrogen released from stimulated reactions.

#Solar cells submerged in the ocean can still generate power, even 10 meters underwater, opening up a new source for powering submerged vessels. buff.ly/sXJZIPz

#Apple’s new Reference Image software is meant to combat #deepfakes. It uses a secure key, but its closed implementation means that people without access to expensive Apple devices might lose credibility with their audience. buff.ly/0XEw5Gu

#Quantum computers need near-absolute-zero temperatures to function. As they scale, increasing their connections increases heat. Startup S-Transistors is creating control electronics out of transistors that can operate in that necessarily cold environment to minimize cabling needs. buff.ly/AHviJPH

Human sweat commonly causes prosthetics to fail by interfering with electrical sensors, which is not ideal for users. What if we used light-based #sensors instead?

The #Nobel Prize in Physics has been awarded to Francis Halzen for his discovery of high-energy #neutrinos, which provide direct paths to their origin. Read how the IceCube Observatory actually works and the way a team of scientists was able to track such an elusive particle: buff.ly/yKfgC1P

Revoy’s electric dollies can attach to semitrucks, turning them into #hybrid vehicles without modifying the engine. A 36-ton truck can run 320 to 400 kilometers on electric power. buff.ly/Ai5xSUn

The #NobelPrize for Medicine just went to the pioneers of optogenetics, a technique that lets scientists control neurons with light! Revisit our 2016 feature on the tiny wireless implants that brought this remarkable capability to freely moving lab mice: buff.ly/miuDBxC
