Nanoparticles inspired by lung fluid improve therapies targeting respiratory system

NASA's Juno spacecraft captured this color-enhanced view of Jupiter's northern hemisphere during its 61st close flyby of the giant planet on May 12, 2024.

When researchers founded Anthropic in 2021, they said the race to build powerful AI was moving too recklessly. They inserted detailed safety measures into their products and marketed their commitment to safety as the corporate quality that distinguished them from competitors—notably OpenAI, the rival company they had left. In March 2026, that reputation was tested when the Trump administration declared that Anthropic was a supply chain risk.

Hannah Ray J Childs propelled her kayak into a rapid on Iowa's Maquoketa River on a recent afternoon and dipped her paddle in the water to swing the front of her boat into the air.

Researchers have developed a method for making simultaneous soft X-ray absorption spectroscopy (XAS) measurements of solid-liquid interfaces and bulk liquids. By controlling the thickness of the liquid layer, they obtained the O K-edge XAS spectrum of bulk H2O from a liquid H2O layer on a thin Au film using the transmission method, and they used the electron-yield method to obtain the XAS spectrum of the H2O/Au interface by measuring the drain currents from the Au surface following soft X-ray ab
