Phys.org / Low oxygen could limit insects' uphill escape from climate warming

Reduced oxygen levels and air pressure at higher elevations may limit insects' ability to move upslope to escape a warming climate, with potential consequences for the essential services they provide, like pollination, according ...

Phys.org / Milky Way's own gravity can mimic dark matter clues, stellar stream simulations suggest

Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like planets in our solar ...

Phys.org / AI model designs potentially stable protein sequences beyond those found in nature

A protein's function is determined by its structure, and structure—the way a protein folds—is determined by its sequence of amino acids, the building blocks of proteins.

Phys.org / Tiny oxygen gaps may determine whether next-generation memory films store data well

Researchers have captured in real time the "birth moment" when the performance of a next-generation memory material is determined. The key lies in controlling oxygen vacancies, microscopic defects created when oxygen atoms ...
