Dec. 22, 2022 — As the supersonic solar wind surges towards Earth, its interaction with our planet's magnetic field creates a shock to deflect its flow, and a foreshock filled with electromagnetic waves. How ...
May 10, 2021 — Researchers show that, unlike the crystalline close packing of spheres, random close packing or jamming of spheres in a container can take place in a broad range of densities and anisotropies. ...
Mar. 4, 2021 — Using data collected in a NASA wind tunnel, researchers replicated the hypersonic flow conditions of a compression ramp flow using Direct Numerical ...
Dec. 15, 2022 — Scientists have designed and fabricated a simple device capable of imaging a gas injected into it in multiple colors in accordance with its gaseous properties, enabling chromatic discrimination of ...
Mar. 31, 2021 — For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than cubic diamonds found in nature and often used in jewelry. Hexagonal diamonds have been found at ...
Nov. 25, 2021 — Researchers have developed a jelly-like material that can withstand the equivalent of an elephant standing on it, and completely recover to its original shape, even though it's 80% ...
Nov. 16, 2021 — Turbulence makes many people uneasy or downright queasy. And it's given researchers a headache, too. Mathematicians have been trying for a century or more to understand the turbulence that ...
Apr. 12, 2022 — When triggered by some external agent, shockwaves can propagate through molecular clouds of gas and dust to create pockets of dense material. At a certain limit, that dense gas and dust collapses and ...
Mar. 15, 2022 — Greenhouse gas emissions from air conditioners are expected to climb as economic growth drives efforts to control both temperature and humidity, according to a new ...
May 19, 2023 — Better understanding the formation of swirling, ring-shaped disturbances -- known as vortex rings -- could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to ...
