Lek-Heng Lim uses tools from algebra, geometry and topology to answer questions in machine learning.

Feelings of loneliness prompt changes in the brain that further isolate people from social contact.

There appear to be too many gamma rays coming from the sun. New higher-energy measurements reveal that this excess continues for a bit, then disappears — a cutoff that could help clarify what’s going on.

Several real-life pathogens can change a host’s behavior against their will. Here’s what we know about these zombie-like infections.

The quantum energy teleportation protocol was proposed in 2008 and largely ignored. Now two independent experiments have shown that it works.

Big Freeze, Big Rip, Big Crunch, Bounce or vacuum decay? Steven Strogatz speaks with theoretical cosmologist Katie Mack about the five ways that scientists think the universe could come to an end.

“Virovores” — organisms that survive and multiply by eating viruses — might influence the flow of energy through ecosystems.

Mathematicians have struggled to understand the moduli space of graphs. A new paper uses tools from physics to peek inside.

Large language models still struggle with basic reasoning tasks. Two new papers that apply machine learning to math provide a blueprint for how that could change.
