Astronomers have found stars dating from a long-ago collision between the Milky Way and another galaxy. The crash helps to explain why the Milky Way looks the way it does.
An experiment at the Fermi National Accelerator Laboratory near Chicago has detected far more electron neutrinos than predicted — a possible harbinger of a revolutionary new elementary particle called the sterile neutrino, though many physicists remain skeptical.
The inventors of a “Swiss army knife” for genome editing received prestigious honors, as did pioneering scientists in astrophysics and neuroscience.
By paying more attention to behaviors, and not just the activity of neurons, two researchers critical of most neuroscience learned how brains make sense of spoken language.
Faced with a navigational challenge, neural networks spontaneously evolved units resembling the grid cells that help living animals find their way.
A roundup of some of the most important discoveries gleaned so far from the Gaia space observatory’s new map of the galaxy.
Zeta values seem to connect distant geometric worlds. In a new proof, mathematicians finally explain why.
Two ways of measuring the universe’s expansion rate yield two conflicting answers. Many point to the possibility of new physics at work, but a new analysis argues that unseen errors could be to blame.
To date the branches on the evolutionary tree of life, researchers are looking at horizontal gene transfers among ancient microorganisms, which once seemed only to muddle the record.
