Extreme conditions prevail inside stars and planets. The pressure reaches millions of bars, and it can be several million degrees hot. Sophisticated methods make it possible to create such states of matter in the laboratory—albeit only for the blink of an eye and in a tiny volume. https://phys.org/news/2024-09-laser-ray-combo-star-conditions.html General Physics Thu, 12 Sep 2024 11:51:08 EDT news645360655 Superconducting wires can transport electricity without loss. This would allow for less power production, reducing both costs and greenhouse gasses. Unfortunately, extensive cooling stands in the way, because existing superconductors only lose their resistance at extremely low temperatures. In the journal Angewandte Chemie, scientist have now introduced new findings about hydrogen sulfide in the H3S form, and its deuterium analog D3S, which become superconducting at the relatively high temperatures of -77 and -107 °C, respectively. https://phys.org/news/2020-09-road-conductors-future.html Materials Science Mon, 14 Sep 2020 11:16:29 EDT news519300986 Coronary artery disease (CAD) is a condition in which plaque forms on the walls of coronary arteries, causing them to narrow. Eventually, this could lead to a heart attack, or death. This condition is now the single largest health problem in the world, with over one million people in the US undergoing cardiac catheterization – where a stent is placed in the artery to prevent blockage – each year. https://phys.org/news/2018-10-clearer-picture-heart-machine.html Computer Sciences Fri, 05 Oct 2018 09:42:26 EDT news457951340 (PhysOrg.com) -- In 2008, scientists built a loudspeaker made of carbon nanotubes that produced sound and music based on the thermoacoustic effect. Now, a different team of scientists has built a loudspeaker made of tiny aluminum wires suspended like a bridge between two supports, producing sound in a similar way. The new wire bridge also has the advantage of being much easier to fabricate than the nanotube device, offering the potential for a wide range of audio applications. https://phys.org/news/2009-11-tiny-music-player-wire-bridge.html General Physics Wed, 04 Nov 2009 09:00:01 EST news176543078
