Stars like our sun may maintain the same rotation pattern for life, contrary to 45 years of theoretical predictions

Researchers at Nagoya University in Japan have conducted the most detailed simulation of the interior of stars and disproved a theory scientists have believed for 45 years: that stars switch their rotation patterns as they age, with poles rotating faster than the equator in older stars. Scientists have now found that this switch may not […]

What’s inside neutron stars? New model could sharpen gravitational-wave ‘tide’ clues

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of atomic nuclei, and they possess some of the strongest gravitational fields of any known objects, surpassed only by black holes. First observed in the 1960s, much of the internal composition of neutron stars is still […]

Material previously thought to be quantum is actually a new, non-quantum state of matter

Magnetic materials in a quantum spin liquid phase are of great interest in the pursuit of exotic state of matter and quantum computation. But in the quantum realm, things are not always what they seem. A study, published in Science Advances and co-led by Rice University’s Pengcheng Dai, found that the material cerium magnesium hexalluminate […]

Water-window X-rays without a synchrotron: How graphite flakes could shrink bioimaging tools

Researchers from Nanyang Technological University, Singapore (NTU Singapore) have found a new way to produce X-rays with wavelengths in what is called the “water window.” This new method holds promise in making bioimaging X-ray machines smaller and more flexible to use.

Large area MoS₂ reduces energy loss in magnetic memory films

Scientists at the University of Manchester have discovered that placing magnetic films on atomically thin molybdenum disulfide (MoS₂) fundamentally changes how they lose energy, a finding that could bring 2D‑material spintronics a step closer to real devices. The team found that growing a widely used magnetic alloy, permalloy, on ultra‑thin MoS₂ alters the film’s internal […]

Can we observe Earth-like exoplanets from our own planet?

Finding Earth-like planets orbiting sun-like stars and identifying signs of life such as oxygen or water is a major goal in astronomy and a key interest for the public. Addressing this challenge speaks directly to one of humanity’s most fundamental questions: Are we alone in the universe? However, these planets are about 10 billion times […]

Gravitational waves reveal hidden structure of galactic centers

A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into each cubic parsec. The team used gravitational-wave data from pulsar timing arrays to probe galactic centers that are otherwise impossible to observe directly.

Can we design sports shoes that don’t squeak? Here’s what the science says

The unofficial soundtrack of every basketball, squash or hard-court tennis match is the constant high-pitched squeak or shriek of the players’ shoes. But can this squeak be designed out of them while retaining the grip?

NASA rules out asteroid smashup on the moon in 2032

Here’s one less thing to worry about—or to look forward to: NASA has ruled out any chance that an asteroid called 2024 YR4 will hit the moon in 2032. Last year, the uncertainty surrounding the space rock’s orbital path held out a slight chance of impact, but fresh observations from NASA’s James Webb Space Telescope […]

A superradiant clock phase emerges when Rydberg atoms meet quantum light, simulations suggest

Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and develop quantum technologies, as they can give rise to exotic and rare phases of matter.

Engineers improve infrared devices using century-old materials

After decades of intense research, surprises in the realm of semiconductors—materials used in microchips to control electrical currents—are few and far between. But with a pair of published papers, materials engineers at Stanford University debut a promising approach to using a well-studied semiconductor to improve infrared light-emitting diodes and sensors. They say the approach could […]

AI-designed diffractive optical processors pave the way for low-power structural health monitoring

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a novel framework for monitoring structural vibrations using diffractive optical processors. This new technology uses artificial intelligence to co-optimize a passive diffractive layer and a shallow neural network, allowing the system to encode time-varying mechanical vibrations into distinct spatiotemporal optical patterns.
