Bright galaxies put dark matter to the test

For the past year and a half, the James Webb Space Telescope has delivered astonishing images of distant galaxies formed not long after the Big Bang, giving scientists their first glimpses of the infant universe. Now, a group ...

Lopsided galaxies shed light on the speed of dark matter

In new research published in Astronomy & Astrophysics, researchers have figured out how to precisely calculate the forces that affect galaxies in tidal cycles. The next stage is to find galaxies sufficiently lopsided in the ...

Coastal chemistry improves methane modeling

Scientists at Oak Ridge National Laboratory are using a new modeling framework in conjunction with data collected from marshes in the Mississippi Delta to improve predictions of climate-warming methane and nitrous oxide emissions ...

New research challenges hunter-gatherer narrative

The oft-used description of early humans as "hunter-gatherers" should be changed to "gatherer-hunters," at least in the Andes of South America, according to groundbreaking research led by a University of Wyoming archaeologist.
