MIT engineers develop a magnetic transistor for more energy-efficient electronics

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it’s a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits that restrict how compact and energy-efficient a transistor can be.MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable smaller, faster, and more energy-efficient circuits. The material’s magnetism strongly

My response to the White House executive order on QC

I’ve been getting emails from journalists asking me to comment on the new White House executive order on quantum computing. Alas, I don’t have time for a long response or interviews since I’m at a beautiful science camp in the California mountains, and heading soon to STOC’2026 in Salt Lake City. But I gave anyone who asked me the following statement, which I thought might be of interest to readers of this blog as well.“I hope that at least some of the new funds made available from this Executi

A rare interstellar visitor triggered a SETI search for alien technology

SETI scientists searched the interstellar object 3I/ATLAS for radio signals that could indicate extraterrestrial technology but found nothing beyond human-made interference. Even so, the rapid-response observations helped confirm the object's natural origin and showcased how future interstellar visitors can be investigated for signs of intelligent life.

A tiny diamond defect could reveal a mysterious new kind of magnetism

A newly proposed quantum sensing technique could make it much easier to identify one of physics’ newest and most intriguing classes of magnets: altermagnets. These unusual materials, discovered only a few years ago, appear to combine the speed and efficiency of antiferromagnets with some of the useful electronic properties of traditional magnets, making them promising candidates for next-generation electronics.

Horizon edge states gain finite description in string theory calculation

Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a variety of cosmological and gravitational phenomena. Two renowned examples of these boundaries are event horizons in black holes and the cosmological horizon of the de Sitter spacetime, a model of an expanding universe with a positive vacuum energy.

Solid-state material turns visible light into high-energy UV at sunlight intensity, expanding solar energy potential

Two cups of warm water don't make one cup of boiling water. But in the quantum world, multiple low-energy photons can combine to produce a single, higher-energy photon.

Meteorite reveals a lost moon-sized world from the dawn of the solar system

A rare meteorite has revealed evidence of a massive lost world that once orbited the young Sun before being destroyed in a catastrophic collision. The discovery suggests some early planets formed from dramatically different materials than Earth and Mars, rewriting part of the solar system’s origin story.

The experiments could unlock new discoveries about the universe while paving the way for powerful future technologies in space and on Earth.

Can Psychedelics Reboot Aging Brains? We’re About to Find Out

An audacious trial will test psylocibin in people over age sixty to see if increases plasticity in healthy aging brains. A handful of healthy senior citizens are about to trip on psylocibin—to see if the psychedelic protects aging brains.Psylocibin, the active ingredient in magic mushrooms, is best known for its ties to 1960s counterculture. But now it may also herald a new genre of mental health treatment. From severe depression to post-traumatic stress disorder, studies have highlighted psyche

Matter may entangle with light far more easily near quantum critical points

Quantum entanglement is a state in which particles are entwined with each other. In this entwined state, the properties of one particle influence the other, even when they aren't physically close to ...

Broken time-reversal symmetry phase in kagome metals may establish conditions for superconductivity

Physicists have long suspected that a peculiar quantum state lurks inside a class of materials known as kagome metals, but proving its existence has been elusive. Now, a team led by Yeongkwan Kim at the Korea Advanced Institute of Science and Technology has performed experiments on a kagome metal that provide the strongest evidence yet for this exotic state.

How languages recycle parts of words to avoid confusion

Many languages recycle words, giving them different meanings. For example, in English, "run" can mean to move quickly but also to manage something, like "run a company." In Spanish, "lengua" is both the word for tongue and language, as in "la lengua española." This type of word reuse is known as colexification.

Investigating quantum and molecular plumbing in nanofluidics research

Our body contains an intricate system of tiny vessels through which blood, water and other molecules flow. When the size of the pipes shrinks to the nanoscale, where only a few molecules can fit side by side, the classical laws of physics governing the behavior of water are influenced by the atomic structure of the walls. "It's not that classical hydrodynamics breaks down, but rather that it gets mixed with the condensed matter physics of the solid walls," says Nikita Kavokine, tenure-track assi

Future astronauts could walk across rocks from deep inside the Moon

A colossal ancient collision may have left some of the Moon’s deepest secrets surprisingly close to future Artemis landing sites. By recreating the impact that formed the giant South Pole-Aitken basin—the Moon’s largest and oldest crater—scientists found that a low-angle strike from a large, iron-cored object blasted material from deep inside the Moon, including mantle rocks.
