Reports that the James Webb Space Telescope killed the reigning cosmological model turn out to have been exaggerated. But astronomers still have much to learn from distant galaxies glimpsed by Webb.

Whether you’re passing secret notes in class or downloading images from a space probe, Reed-Solomon codes offer an ingenious way to embed information and correct for errors.

In three-dimensional space, the surface of a black hole must be a sphere. But a new result shows that in higher dimensions, an infinite number of configurations are possible.

In Shang-Hua Teng’s work, theoretical and practical questions have long been intertwined. Now he’s turning his focus to the impractical.

Depression has often been blamed on low levels of serotonin in the brain. That answer is insufficient, but alternatives are coming into view and changing our understanding of the disease.

Two teams have made photons act as if time were simultaneously flowing in two directions. The experiments demonstrate a way to potentially boost the performance of quantum devices.

Theory has it that “Population III” stars brought light to the cosmos. The James Webb Space Telescope may have just glimpsed them.

The critical brain hypothesis suggests that neural networks do their best work when connections are not too weak or too strong.

A wave of research improves reinforcement learning algorithms by pre-training them as if they were human.

A new proof shows that a knot some thought would contradict the famed slice-ribbon conjecture doesn’t.

Richard Feynman’s path integral is both a powerful prediction machine and a philosophy about how the world is. But physicists are still struggling to figure out how to use it, and what it means.

“Liquid” neural nets, based on a worm’s nervous system, can transform their underlying algorithms on the fly, giving them unprecedented speed and adaptability.

Type Ia supernovas are astronomers’ best tools for measuring cosmic distances. In a first, researchers have managed to re-create one on a supercomputer, giving a boost to a leading hypothesis for how they form.

As The Joy of Why podcast returns for a second season, producer Polly Stryker and host Steven Strogatz invite listeners to join them and their brilliant new guests on another voyage of discovery.

Is it possible to fill space “cubically” with shapes that act like spheres? A proof at the intersection of geometry and theoretical computer science says yes.

Regenerative medicine researcher Kristy Red Horse’s discoveries may someday help damaged hearts heal better. Her stewardship of her Native American heritage may advance science in other ways too.

The neocortex of our brain is the seat of our intellect. New data suggests that mammals created it with new types of cells that they developed only after their evolutionary split from reptiles.

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.

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

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

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