An idea derived from string theory suggests that dark matter is hidden in an as-yet-unseen extra dimension. Scientists are racing to test the theory to see if it holds up.

Is This New 50-Year Battery for Real?

BetaVolt’s nuclear battery lasts for decades, but you won’t see one in your next iPhone—powering a mobile device would require a cell the size of a yak.

Google’s Chess Experiments Reveal How to Boost the Power of AI

By rewarding computers that combined different approaches to solve chess puzzles, Google created an enhanced AI that could defeat its existing champion, AlphaZero.

A Celebrated Cryptography-Breaking Algorithm Just Got an Upgrade

Two researchers have improved a well-known technique for lattice basis reduction, opening up new avenues for practical experiments in cryptography and mathematics.

How to Guarantee the Safety of Autonomous Vehicles

As computer-driven cars and planes become more common, the key to preventing accidents, researchers show, is to know what you don’t know.

Why Is Our Solar System Flat?

It started as a big old ball of dust, so how did it end up like a giant pancake? Our resident physicist tells the true story using fake forces.

Fiber Optics Bring You Internet. Now They’re Also Listening to Trains

Par : Matt Simon
“Distributed acoustic sensing” looks for disturbances in fiber to detect earthquakes and even insects. Can it also improve rail safety?

Scientists Just Discovered a New Type of Magnetism

In an atomically thin stack of semiconductors, a mechanism unseen in any natural substance causes electrons’ spins to align.

How to Convince Your Flat-Earth Friends the World Is Round

Two experiments you can do yourself to finally, definitively put this question to rest.

Why the Polar Vortex Is Bad for Balloon Artists

Leave a balloon out in the cold and it’ll shrink and look pathetic. Sorry, but that’s the law—the ideal gas law.

These Rogue Worlds Upend the Theory of How Planets Form

Scientists have recently discovered scores of free-floating planets that defy classification—forcing them to rethink their theories of star and planet formation.

The Tantalizing Mystery of the Solar System’s Hidden Oceans

The moons orbiting Jupiter and Saturn appear to have subsurface oceans which could support life beyond Earth. But it’s not clear why these seas exist at all.

School of Rock: The Physics of Waves on Guitar Strings

Playing the guitar is an art form. But the good vibrations you hear are a science.

Leader of Elite French University Offers to Step Aside, for Now

Mathias Vicherat, the director of Sciences Po, has exchanged accusations of domestic violence with his partner. The police are investigating.

Students at Sciences Po staged a sit-in on campus last week to demand the resignation of Mathias Vicherat, the director of the university. The banner reads, “Protected aggressors, abandoned victims, Sciences Po, paradise of impunity.”

What Can You Do With an Einstein?

Earlier this year, mathematicians discovered a unique shape. Now do-it-yourselfers have found ingenious ways to put it to use.

Math Scores Dropped Globally, but the U.S. Still Trails Other Countries

In a global exam for 15-year-olds, only a handful of places, including Singapore, Japan and Australia, kept math performance high through the pandemic.

In math, the U.S. ranked 28th out of 37 participating countries from the Organization for Economic Cooperation and Development, a group that includes mostly industrialized democracies.

An Invisible ‘Demon’ Lurks in an Odd Superconductor

Physicists have long suspected that hunks of metal could vibrate in a peculiar way that would be all but invisible. Now physicists have spotted these “demon modes.”

Dr. Nergis Mavalvala Detected the First Gravitational Wave. Her Work Doesn’t Stop There

The dean of MIT’s School of Science embraces skepticism and failure, and she wants the next generation of scientists to jump right in.
