Phys.org / Using plutonium to probe the universe: Magneto‑ν experiment advances dark matter and neutrino research

Astronomers can't see dark matter directly, but they know it's there: Its gravity shapes galaxies and the large-scale structure of the cosmos. In an effort to uncover the composition of this hidden mass, a team at Lawrence ...

Phys.org / Forty forest drought experiments reveal trees show little physiological acclimation

Forests support much of the world's biodiversity and play a vital role in regulating Earth's climate, but they are increasingly exposed to drought. To understand the potential consequences of drought, a key question is whether ...

Phys.org / JWST reveals a race against time for forming planets

Planets form from disks of gas and dust around young stars, but the gas needed for growth does not last forever. New observations from NASA's James Webb Space Telescope (JWST) now offer a new view of how this gas escapes ...
