A paper in Nature reports the discovery of a superconductor that operates at room temperatures and near-room pressures. The claim has divided the research community.

New calculations suggest that the event horizons around black holes will ‘decohere’ quantum possibilities — even those that are far away.

By replacing thousands of equations with just one, ecology modelers can more accurately assess how close fragile environments are to a disastrous “tipping point.”

Cryptographers have shown how perfect security can undermine machine learning models.

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.
