U.S. researchers face new restrictions on publishing with foreign collaborators - Science | AAAS

An ideologue should hate paleontology. It is always turning up something new. And sometimes the new stuff is really inconvenient. At one time, Neanderthal man was our dumb cousin. His stupidity caused him to lose the Darwinian battle for survival. National Geographic had the story back then.

This is the sound of our solar system's giants. By converting astronomical data into audio, we can now 'listen' to Jupiter, Saturn, and Uranus. This process, called sonification, translates light detected from the planets into unique and ethereal soundscapes.

While these grainy, black-and-white images might not look like much today, they were a huge deal at the time.

Chen and his team pioneered an innovative "negative-curvature interface" strategy in alloys. The graphic illustrates how negative-curvature interfaced nanoprecipitates harden the novel microstructures of the designed alloy. Credit: Nature Communications (2026). DOI: 10.1038/s41467-026-74629-1 Metallic materials used in extremely cold environments must maintain high strength, ductility and fracture toughness to support applications in aerospace, clean energy, superconducting systems and deep-space exploration. However, traditional alloys often suffer performance degradation at ultralow temperatures because of the long-standing trade-off between strength, ductility and toughness. Although metals may become stronger at lower temperatures, they can also become more brittle and prone to fracture.
