An anonymous reader quotes a report from Ars Technica: GPS is facing a major interference threat from a 5G network approved by the Federal Communications Commission, U.S. military officials told Congress in a hearing on Wednesday. In testimony to the Senate Committee on Armed Services, Department of Defense Chief Information Officer Dana Deasy disputed the FCC’s claims that conditions imposed on…

Trump Administration Drafting ‘Artemis Accords’ Pact For Moon Mining
The Trump administration is drafting a legal blueprint for mining on the moon under a new U.S.-sponsored international agreement called the Artemis Accords, Reuters reported Wednesday. From the report: The agreement would be the latest effort to cultivate allies around NASA’s plan to put humans and space stations on the moon within the next decade, and comes as the civilian space…
What are gravitational waves?
First postulated by Albert Einstein in 1916 but not observed directly until September 2015, gravitational waves are ripples in spacetime. Source: https://earthsky.org/space/definition-what-are-gravitational-waves…
NASA’s Plan To Turn the ISS Into a Quantum Laser Lab
Daniel Oberhaus writes via Wired: Later this summer, physicists at the Argonne and Fermi national laboratories will exchange quantum information across 30 miles of optical fiber running beneath the suburbs of Chicago. One lab will generate a pair of entangled photons — particles that have identical states and are linked in such a way that what happens to one happens to…
Pentagon Watchdog Clears Microsoft’s $10 Billion Win Over Amazon
The Defense Department’s watchdog found no evidence that the Pentagon’s controversial decision to award a $10 billion cloud-computing contract to Microsoft was the result of interference from President Donald Trump, though it said its probe was limited by the White House. From a report: The 317-page report issued Wednesday by the inspector general also found that giving the JEDI contract to…
Will SETI 2.0 lead to a discovery of intelligent aliens?
2020 has been an exciting year so far for SETI – the search for extraterrestrial life – in terms of new technological developments and strategies. Source: https://earthsky.org/space/seti-breakthrough-listen-new-technologies-and-strategies…
FCC To Vote On Adding 6Ghz Band To Wi-Fi 6 To Improve Speeds
An anonymous reader quotes a report from Gizmodo: Devices with Wi-Fi 6 started rolling out at the end of 2019, but now, a new vote proposed by the FCC could open up the 6Ghz band to unlicensed wifi and add a massive speed boost to wireless gadgets. Backed by Chairman Pai, the FCC vote is scheduled to take place on April…
Researchers demonstrate first terahertz quantum sensing
Quantum physicists rely on quantum sensing as a highly attractive method to access spectral regions and detect photons (tiny packets of light) that are generally technically challenging. They can gather sample information in the spectral region of interest and transfer the details via biphoton correlations into another spectral range with highly sensitive detectors. The work is specifically beneficial for terahertz radiation…
Trump Signs Law Banning Use of Federal Funds To Purchase Huawei Equipment
President Trump on Thursday signed into law a bill banning the use of federal funds to purchase equipment from telecom companies deemed a national security threat, such as Chinese telecom group Huawei. From a report: The Secure and Trusted Communications Act, which the Senate passed in February and the House approved last year, will also require the Federal Communications Commission (FCC)…
Photon trick lets you bend the rules of quantum physics
A basic rule of quantum physics is that knowing too much about an experiment will break quantum interference, but now physicists have discovered a way to bend that rule Source: https://www.newscientist.com/article/2232762-photon-trick-lets-you-bend-the-rules-of-quantum-physics/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
