The Biggest Breakthroughs in Mathematics: 2025

December 19, 2025

2025 marked a historic year in mathematics. Researchers solved a major case of Hilbert’s ambitious sixth problem, proved a sweeping new theorem about hyperbolic surfaces, and settled the longstanding three-dimensional Kakeya conjecture.

The Biggest Breakthroughs in Physics: 2025

December 17, 2025

In 2025, physicists spotted a paradigm-shifting new black hole, doubled down on weakening dark energy, and discovered that the Earth’s deep interior may be more connected than previously thought, reshaping our picture of the planet’s engine.

Carlo Rovelli: ‘Time Is an Illusion’

October 29, 2025

Carlo Rovelli discusses his research on time and his view that it should not appear in the quantum theory of gravity.

A Once-in-a-Century Proof: The Kakeya Conjecture

October 6, 2025

What is the Kakeya conjecture, and what are the ideas behind the new groundbreaking proof?

Is Information a Fundamental Force of the Universe?

August 4, 2025

Robert Hazen and Michael Wong discuss their bold proposal for a new law of nature, centered around the idea that information is as fundamental to the cosmos as mass, energy or charge.

Mirror Molecules: The Symmetry Rule Life Never Breaks

June 7, 2025

Most organic molecules have a mirror-image twin. This concept is known as chirality. Yet life only uses one chiral molecule, not the other. The reason for this asymmetry is one of the greatest mysteries of biology.

How to ‘See’ the 4th Dimension with Topology

May 15, 2025

Mathematician Maggie Miller explores the strange and fascinating world of 4D topology — the study of shapes, or manifolds, that resemble flat Euclidean space when viewed up close.

Amateurs Solve a Famous Computer Science Problem On Discord

April 21, 2025

A team of amateurs recently came together in an online collaboration called the Busy Beaver Challenge to pin down the value of BB(5), the fifth “busy beaver” number — a notoriously difficult problem in theoretical computer science.
