The brain not only helps to regulate immune responses, but also stores and retrieves “memories” of them.

New work establishes a tighter connection between the rank of a polynomial and the extent to which it favors particular outputs.

In nonreciprocal systems, where Newton’s third law falls apart, “exceptional points” are helping researchers understand phase transitions and possibly other phenomena.

Results from neural networks support the idea that brains are “prediction machines” — and that they work that way to conserve energy.

Quantum bits are fussy and fragile. Useful quantum computers will need to use an error-correction technique like the one that was recently demonstrated on a real machine.

Ana Caraiani seeks to unify mathematics through her work on the ambitious Langlands program.

The Chinese remainder theorem is an ancient and powerful extension of the simple math of least common multiples.

Through his encyclopedic study of the electron, an obscure figure named Stefano Laporta found a handle on the subatomic world’s fearsome complexity. His algorithm has swept the field.

A mathematical model shows how a thermodynamic mechanism could have made protocells split in two.

By carefully constructing a multidimensional and well-connected graph, a team of researchers has finally created a long-sought locally testable code that can immediately betray whether it’s been…

The solution to our puzzle about Euler’s number explains why e pops up in situations that involve optimality.

The spate of furious wildfires around the world during the past decade has revealed to ecologists how much biodiversity and “pyrodiversity” go hand in hand.

No matter how much we’d like to eradicate SARS-CoV-2, it may be better to settle for other forms of control.

One of the first goals of quantum computing has been to recreate bizarre quantum systems that can’t be studied in an ordinary computer. A dark-horse quantum simulator has now done just that.

The James Webb Space Telescope has the potential to rewrite the history of the cosmos and reshape humanity’s position within it. But first, a lot of things have to work just right.

Rapid advances in large-scale connectomics are beginning to spotlight the importance of individual variations in the neural circuitry. They also highlight the limitations of “wiring diagrams” alone.

Tiny amounts of artificial noise can fool neural networks, but not humans. Some researchers are looking to neuroscience for a fix.

The “gravitational memory effect” predicts that a passing gravitational wave should forever alter the structure of space-time. Physicists have linked the phenomenon to fundamental cosmic symmetries…

More than 30 years ago, Andreas Floer changed geometry. Now, two mathematicians have finally figured out how to extend his revolutionary perspective.

A central pillar of cosmology — the universe is the same everywhere and in all directions — is surviving a storm of possible evidence against it.
