☆ Archimedes’ death ray might have worked, teen science project suggests
  + stars: | 2024-03-08 | by ( Taylor Nicioli | ) edition.cnn.com   time to read: +7 min
But one fabled device has left scientists speculating on its existence for hundreds of years — the death ray. For his 2022 science project, Sener recreated the Archimedes screw, a device for raising and moving water. Sener found the death ray to be one of the more intriguing devices — sometimes referred to as the heat ray. Archimedes’ death ray is more commonly speculated to have been an array of several mirrors or polished shields. Sener’s mom, Melanie, was not surprised by her son’s choice in science project.

☆ US Moves Closer to Underground Testing of Nuclear Weapons Stockpile Without Any Actual Explosions

The hope is to answer many pivotal questions about whether the nation's aging nuclear weapons still work as designed. Political Cartoons View All 1202 ImagesDuring the Cold War, those questions were answered by actually setting off nuclear explosions. The experimental machine the length of a football field eventually will sit 1,000 feet (304 meters) below the ground at the Nevada National Security Site. Custer said above-ground facilities have tested explosive behaviors of other materials but the Scorpius experiments will use real plutonium, which is unique. Assembly testing is planned through most of 2025 before the Nevada site will move the injector underground.

☆ Self-healing metal? It's not just the stuff of science fiction

Self-healing metal is still just science fiction, right? Metal fatigue can cause catastrophic failures in areas including aviation - jet engines, for instance - and infrastructure - bridges and other structures. It occurs at the nanoscale, and we have yet to be able to control the process," Boyce added. Scientists in the past have fashioned some self-healing materials, mostly plastics. Study co-author Michael Demkowicz, a Texas A&M University professor of materials science and engineering, predicted self-healing in metal a decade ago.

Efforts to address the security of EV charging stations are in early stages. A U.S. infrastructure law passed in 2021 includes $7.5 billion in funding for states to expand EV charging stations. Newsletter Sign-up WSJ Pro Cybersecurity Cybersecurity news, analysis and insights from WSJ's global team of reporters and editors. Tesla is poised to dominate EV charging in the U.S., and auto manufacturers including General Motors, Ford, Volvo and Rivian signed on to adopt Tesla’s charging standard this year. Last year, the city of Amsterdam for the first time included cybersecurity requirements in a public tender for public EV charging stations.

☆ Balloons detect mysterious sounds in the stratosphere below the human hearing limit. Scientists can't explain.
  + stars: | 2023-05-13 | by ( Morgan Mcfall-Johnsen | ) www.businessinsider.com   time to read: +6 min
Solar-powered balloons are recording mysterious sounds below human hearing in the stratosphere. These balloons listen to the Earth from a dozen miles up, but not in frequencies that the human ear can detect. "In the infrasound domain our planet is very rich," Bowman, a scientist at Sandia National Laboratories, told Insider. "I think one of the reasons humans can't hear infrasound is because we'd go nuts if we could." But Bowman wants to see more people flying infrasound-recording stratosphere balloons.
☆ Pentagon successfully flight tests hypersonic weapon components
  + stars: | 2022-10-26 | by ( Mike Stone | ) www.reuters.com   time to read: +2 min
[1/2] The U.S. Department of Defense launches a sounding rocket from NASA's launch range at Wallops Flight Facility carrying hypersonic weapon experiments that will inform the development of the hypersonic class of weapons, on Wallops Island, Virginia, U.S., October 26, 2022. Wednesday's test was intended to validate future aspects of the Navy's Conventional Prompt Strike (CPS) and the Army's Long Range Hypersonic Weapon (LRHW). Glide bodies are different from their air-breathing hypersonic weapon cousins, which use scramjet engine technology and the vehicle's high speed to forcibly compress incoming air before combustion to enable sustained flight at hypersonic speeds. Companies such as Lockheed Martin Corp and Raytheon Technologies Corp are working to develop U.S. hypersonic weapon capability.
