World’s most sensitive table-top experiment sets new limits on very high-frequency gravitational waves

The world’s most sensitive table-top interferometric system—a miniature version of miles-long gravitational-wave detectors like LIGO—has completed its first science run.

Nobel Prize in physics awarded for ultracold electronics research that launched a quantum technology

Quantum mechanics describes the weird behavior of microscopic particles. Using quantum systems to perform computation promises to allow researchers to solve problems in areas from chemistry to cryptography that have so many possible solutions that they are beyond the capabilities of even the most powerful nonquantum computers possible.

Tiny engine runs hotter than the sun to probe the frontiers of thermodynamics

Scientists have created the world’s hottest engine running at temperatures hotter than those reached in the sun’s core. The team from King’s College London and collaborators believe their platform could provide an unparalleled understanding of the laws of thermodynamics on a small scale, and provide the foundation for a new, efficient way to compute how proteins fold—the subject of last year’s Nobel Prize in Chemistry.

Nanoscale X-ray imaging reveals bulk altermagnetism in MnTe

Magnetic materials have been known since ancient times and play an important role in modern society, where the net magnetic order offers routes to energy harvesting and data processing. It is the net magnetic moment of ferromagnets that has so far been key to their applications, with an alternative type of magnetic material, the antiferromagnet, deemed “useless” by their discoverer Louis Néel in his Nobel Prize lecture.

Simulations unveil the electrodynamic nature of black hole mergers and other spacetime collisions

Gravitational waves are energy-carrying waves produced by the acceleration or disturbance of massive objects. These waves, which were first directly observed in 2015, are known to be produced during various cosmological phenomena, including mergers between two black holes that orbit each other (i.e., binary black holes).

Mars dust devils mapped in detail, revealing faster winds than expected

Combing through 20 years of images from the European Space Agency’s Mars Express and ExoMars Trace Gas Orbiter spacecraft, scientists have tracked 1,039 tornado-like whirlwinds to reveal how dust is lifted into the air and swept around Mars’s surface.

Composing crews for Mars missions: Team diversity may foster resilience

Simulation results highlight how team composition shapes stress, health, performance, and cohesion in long-duration space missions, according to a study published October 8, 2025, in the open-access journal PLOS One by Iser Pena and Hao Chen of the Stevens Institute of Technology, U.S. In particular, team diversity in personality traits may contribute to greater resilience under extended isolation and operational load.

Open source mega-constellations could solve overcrowding

Duplicating expensive resources is expensive and wasteful, and most people would agree it’s unnecessary. However, the planned increase in major satellite constellations is currently causing a massive duplication of resources as individual companies and even countries try to set up their own infrastructure in space.

Cosmic tug-of-war: Gravity reshapes magnetic fields in star clusters

Astronomers have captured the clearest picture yet of how massive stars are born, revealing a dramatic interplay between gravity and magnetic fields in some of our galaxy’s most dynamic star forming regions. A team led by Dr. Qizhou Zhang from the Center for Astrophysics | Harvard & Smithsonian used the Atacama Large Millimeter/submillimeter Array (ALMA) to conduct the largest and most detailed survey to date of magnetic fields in 17 regions where clusters of massive stars are forming.

Research shines light on ‘double-yielding’ behavior in soft materials

For decades, scientists have observed, but been unable to explain, a phenomenon seen in some soft materials: When force is applied, these materials exhibit not one, but two spikes in energy dissipation, known as overshoots. Because overshoots are generally thought to indicate the point at which a material yields, or transitions from solid-like to fluid-like behavior, the dual response was therefore assumed to indicate “double yielding”—the idea that to fully fluidize a material, it needed to yield twice.

Researchers discover a hidden atomic order that persists in metals even after extreme processing

For decades, it’s been known that subtle chemical patterns exist in metal alloys, but researchers thought they were too minor to matter—or that they got erased during manufacturing. However, recent studies have shown that in laboratory settings, these patterns can change a metal’s properties, including its mechanical strength, durability, heat capacity, radiation tolerance, and more.
