New experiments show that the brain distinguishes between perceived and imagined mental images by checking whether they cross a “reality threshold.”

Simple math can help explain the complexities of the newly discovered aperiodic monotile.

Researchers uncover striking parallels in the ways that humans and machine learning models acquire language skills.

In steganography, an ordinary message masks the presence of a secret communication. Humans can never do it perfectly, but a new study shows it’s possible for machines.

Several areas of physics suggest reasons to think that unobservable universes with different natural laws could lie beyond ours. The theoretical physicist David Kaplan talks with Steven Strogatz about the mysteries that a multiverse would solve.

Memories may affect how well the brain will learn about future events by shifting our perceptions of the world.

For the first time, mathematicians have proved that planetary orbits in a solar system will always be unstable.

A new theory describes how particle interactions fuel fast magnetic reconnection, the process behind solar flares and other astrophysical jets.

Today’s language models are more sophisticated than ever, but they still struggle with the concept of negation. That’s unlikely to change anytime soon.
