Second Google AI Ethics Leader Fired, She Says Amid Staff Protest
Alphabet’s Google on Friday fired scientist Margaret Mitchell, she said in a Twitter post, after weeks of being under investigation for moving thousands of files outside the company amid a battle over research freedom and diversity. From a report: Google’s ethics in artificial intelligence research unit has been under scrutiny since December’s dismissal of scientist Timnit Gebru, which prompted protest from…
Quantum tunneling in graphene advances the age of terahertz wireless communications
Scientists from MIPT, Moscow Pedagogical State University and the University of Manchester have created a highly sensitive terahertz detector based on the effect of quantum-mechanical tunneling in graphene. The sensitivity of the device is already superior to commercially available analogs based on semiconductors and superconductors, which opens up prospects for applications of the graphene detector in wireless communications, security systems, radio…
JADES will go deeper than the Hubble Deep Fields
Astronomers announced this month that a new deep-field survey called JADES will be carried out with the James Webb Space Telescope, Hubble’s much-anticipated successor. The Webb is due to launch later this year. Source: https://earthsky.org/space/jades-deep-field-surveys-epoch-of-1st-galaxies…
China’s huge FAST telescope to open to international observers
FAST’s 500-meter (1,640-foot) dish makes it the world’s largest single-dish radio observatory. It’s expected to open to international observers in 2021. Source: https://earthsky.org/space/worlds-largest-radio-telescope-china-fast…
Russia Breached Update Server Used by 300,000 Organizations, Including the NSA
Sunday Reuters reported that “a sophisticated hacking group” backed by “a foreign government” has stolen information from America’s Treasury Department, and also from “a U.S. agency responsible for deciding policy around the internet and telecommunications.” The Washington Post has since attributed the breach to “Russian government hackers,” and discovered it’s “part of a global espionage campaign that stretches back months, according…
Google’s Look To Speak Taps Gaze-Tracking AI To Help Users With Impairments Communicate
Google today launched an experimental app for Android that leverages AI to make communication more accessible for people with speech and motor impairments. Called Look to Speak, it tracks eye movements to let people use their eyes to select prewritten, customizable phrases and have them spoken aloud. From a report: Approximately 18.5 million people in the U.S. have a speech, voice,…
Research produces intense light beams with quantum correlations
The properties of quantum states of light are already leveraged by such highly sophisticated leading-edge technologies as those of the latest sensitivity upgrades to LIGO, the Laser Interferometer Gravitational-Wave Observatory, deployed to detect gravitational waves since September 2015, or the encryption keys used for satellite on-board security. …
Physicists propose using atomic clocks of GPS network to detect exotic ultralight fields
A team of physicists from the U.S., Poland and Germany proposes to use quantum sensor networks such as atomic clocks of the GPS network or sensors from the Gnome collaboration (a network of shielded atomic magnetometers made up of 13 stations placed strategically on four continents—each of which is equipped with a magnetometer that has sub-picotesla sensitivity) to detect exotic ultralight…
America’s ‘Cyber Command’ Is Trying to Disrupt the World’s Largest Botnet
The Washington Post reports: In recent weeks, the U.S. military has mounted an operation to temporarily disrupt what is described as the world’s largest botnet — one used also to drop ransomware, which officials say is one of the top threats to the 2020 election. U.S. Cyber Command’s campaign against the Trickbot botnet, an army of at least 1 million hijacked…
