Boron arsenide semiconductor sets record in quantum vibrations

You may not be able to hear it, but all solid materials make a sound. In fact, atoms—bound in lattices of chemical bonds—are never silent nor still: Under the placid surface of each and every object in our surroundings, a low hum hovers or a high-energy squeak titters.

Chandra resolves why black holes hit the brakes on growth

Astronomers have an answer for a long-running mystery in astrophysics: why is the growth of supermassive black holes so much lower today than in the past? A study using NASA’s Chandra X-ray Observatory and other X-ray telescopes found that supermassive black holes are unable to consume material as rapidly as they did in the distant past. The results appeared in the December 2025 issue of The Astrophysical Journal.

Fish gill-inspired panels reveal path to efficient thermal mixing

A fascination with fish gills has led researchers at Cornell to develop a bio-inspired approach to mixing heat and molecules in fluids—findings that could inform future biomedical devices, heat exchangers and soft robotics.

NASA to ‘pause’ orbital lunar space station project

NASA’s chief on Tuesday said the US space agency “intends to pause” its Gateway project that would have created a space station in orbit around the moon, instead shifting focus toward “building a lunar base.”

CERN hails delicate test on transporting antimatter as a scientific success

Scientists in Geneva took some antiprotons out for a spin—a very delicate one—in a truck, in a never-tried-before test drive that has been deemed a success.

A solar system in the making? Two planets spotted forming in disk around young star

Astronomers have observed two planets forming in the disk around a young star named WISPIT 2. Having previously detected one planet, the team has now employed European Southern Observatory (ESO) telescopes to confirm the presence of another. These observations, and the unique structure of the disk around the star, indicate that the WISPIT 2 system could resemble a young solar system.

A spinel crystal structure exhibits unusual, pressure-induced superconductivity

Superconductors are materials that conduct electricity with an electrical resistance of zero. Superconductivity is generally observed when materials are cooled down to extremely low temperatures. In some cases, however, like in so-called high-temperature superconductors, this property emerges at higher temperatures.

XRISM identifies gamma Cas X-ray origin, solving a 50-year-old stellar mystery

Visible to the naked eye in the constellation Cassiopeia, the star γ Cas has puzzled astrophysicists for half a century. It emits X-rays of an intensity and temperature incompatible with what one would expect from an ordinary massive star. Observations, carried out using the Resolve instrument aboard the Japanese XRISM telescope, now allow us to attribute this emission to the white dwarf orbiting γ Cas. This also confirms the existence of a family of binary systems long predicted to exist but never identified.

Shift in key cosmic inflation measurement could be a statistical artifact

For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally accepted that the universe expanded exponentially in the first fraction of a second after the Big Bang. Researchers use ns, the scalar spectral index, to characterize how primordial density fluctuations were distributed across different length scales in the early universe. The value of ns is a central observable in inflationary cosmology, since different inflationary scenarios predict distinct values for this quantity, making it a powerful discriminator between models.
