Researchers have completely suppressed superconductivity in magic-angle graphene by screening interactions between electrons, helping resolve a long-running debate about the origin of the phenomenon.

How Mercury formed its graphite crust and core

As the BepiColombo mission prepares to enter the final phase of its journey to Mercury, a series of studies conducted by researchers at the University of Liège and KU Leuven sheds new light on the early stages of the evolution of the planet closest to the sun. Using experimental petrology, the researchers are reconstructing in the laboratory the formation of Mercury’s core, the crystallization of its magma ocean and the formation of its mantle. The studies are published in Earth and Planetary Science Letters, Nature Communications and Advances in Geochemistry and Cosmochemistry.

Embedded platinum channels bring nanoscale spin-based thermoelectric conversion to bulk materials

A joint research team from NIMS and the University of Tokyo has developed a new composite in which three-dimensional nano-interfaces are distributed throughout the material by coating the surfaces of magnetic-insulator powders with a metal and sintering them. Using this structure, the team succeeded in observing thermoelectric conversion driven by spins in an insulator, a phenomenon previously observed only at nanoscale thin-film interfaces, in a macroscale material.

Particle shape and size predict asteroid strength, revealing Bennu’s surface is 50 times weaker than ground coffee

In a new Nature Communications study, researchers developed a universal scaling framework for the strength of granular asteroids, showing that their tensile strength can be predicted from the size and shape of their constituent particles.

Turbulent times for star formation in Stephan’s Quintet

Star formation in galaxies is closely linked to molecular gas. In the distant past, when galaxy interactions were more common, these encounters compressed molecular gas, causing dense clouds to collapse under their own gravity and form new stars.

Betelgeuse’s atmosphere is becoming spotty and asymmetric—and a nearby companion could be shaping the pattern

For the first time since its dramatic dimming in 2020, a team of astronomers has observed the inner atmosphere of Betelgeuse using the Atacama Large Millimeter Array (ALMA). Led by Bill Dent at the University of Manchester, the team found that the giant star’s inner atmosphere has become increasingly uneven and asymmetric, in a way that could be connected to a far smaller companion star.

Ultrafast electrons and lasers reveal unexpectedly strong radiation signals in common semiconductors

Detecting radiation is key to technologies ranging from particle accelerators and scientific instruments to medical imaging and security screening. But current detectors must often make trade-offs, providing signals that are strong but slow or fast but weak. The trade-off between signal strength and speed can limit precision detection.

Soft nanoscale confinement prevents ice, exposing water’s liquid-to-glass transition

An international collaboration of researchers has used ANSTO’s facilities to uncover new properties of one of the most fundamental everyday materials, water, and answer an important scientific question. The findings, published in Nature Communications, have practical implications for understanding water at very low temperatures. The findings are relevant to cryopreservation of biological materials, food-freezing technologies and understanding water in living cells, where it is often confined at the nanoscale.
