[ad_1] When a supermassive black hole features such jets, it’s classified as a blazar. Astronomers posit that the magnetic poles of the black hole channel the energy up from the accretion disc and shoot it out with a tremendous amount of energy — the jet captured in the image is traveling at about 0.995 times […]

Amazon will deliver at-home COVID-19 test kits in Seattle trial
[ad_1] Every driver involved has been trained in handling medical material, Amazon told CNBC. The tests revolve around the familiar swabs used at drive-through testing locations. If a recipient tests positive, healthcare workers will get in touch. Amazon Care director Kristen Helton said in a statement that the company knows fighting COVID-19 will require help […]
NASA warns Moon base plans might slip by a year
[ad_1] Loverro stressed that NASA wasn’t ditching the Gateway. Rather, he saw the administration pursuing a slower spending increase that would help attract foreign partners. The statements (along with delays in Boeing’s Space Launch System) suggest that NASA’s schedule for the Artemis program might be too aggressive. Critics have argued that the White House’s timetable, […]

[ad_1] Exclusive: ‘Dead Sea Scrolls’ at the Museum of the Bible are all forgeriesMichael GreshkoNational Geographic When the Museum of the Bible opened in Washington, DC in 2017, it funded a research project that examined pieces of what was thought to be Dead Sea Scroll fragments. In 2018, the museum announced that all five sections […]
Robot learns to set the dinner table by watching humans
[ad_1] To nudge the robot toward the right outcome, the team set criteria that helps the robot satisfy its overall beliefs. The criteria can satisfy the formulas with the highest probability, the greatest number of formulas or even those with the least chance of failure. A designer could optimize a robot for safety if it’s […]
NASA wants students’ help designing tech for the Moon and Mars
[ad_1] The awards will be relatively modest at $15,000 to $50,000, but NASA stressed that this doesn’t necessarily involve tangible products. It can also involve research that fills “knowledge gaps” or reduces risks, for instance. Proposals are due by April 24th. The competition may not lead to a major breakthrough in NASA’s Moon and Mars […]
AI can help find more places to store captured CO2 underground
[ad_1] The team trained a convolutional neural network to find the “hidden correlations” in components of high-frequency data from simulated earthquakes. The AI learned how to find patterns that could be used to infer the ‘missing’ low frequencies, to put it another way. The result is an algorithmic system that, in the right circumstances, can […]
Smithsonian opens up 2.8 million images to the public
[ad_1] The Smithsonian is encouraging the public to view, use and reuse the content however they see fit. The collection is listed under a Creative Commons Zero (CC0) license, which removes previous restrictions and copyrights, and it includes everything from portraits of Ida B. Wells to images of Amelia Earhart’s Lockheed Vega 5B, 3D models […]
AI discovers antibiotic that kills even highly resistant bacteria
[ad_1] The team succeeded by developing a system that can find molecular structures with desired traits (say, killing bacteria) more effectively than past systems. Unlike previous methods, the neural networks learn representations of molecules automatically, mapping them into continuous vectors that help predict their behavior. Once ready, the researchers trained their AI on 2,500 molecules […]
Minuscule ID chips could help spot even the smallest counterfeits
[ad_1] The security itself is relatively strong. The chip relies on elliptic curve cryptography that uses a mix of public and private keys to only reveal data to valid readers. You can’t just snoop on wireless traffic to determine which devices are involved and what’s being sent. As is often the case, there’s more to […]
