Researchers have developed and tested a new locking method for gravitational wave detectors that will advance the discovery of distant black holes and neutron stars colliding.
Atoms confined to a single line can bind into clusters called Bethe strings. A new experiment points to a mix of many such clusters, though the evidence is still indirect.
Researchers used the European XFEL to create X-ray flashes that were not only extremely short but also reached record intensity for this type of pulse. The researchers focused the X-rays to an area roughly 100,000 times smaller than the cross section of a typical human hair. This concentrated the X-ray light into a tiny but extremely powerful spot. The method could enable detailed studies of how electrons behave in atoms and molecules and, in the long term, could even allow researchers to control electrons during chemical reactions. The team has now published the results of the experiment, carried out in April 2026, in the journal Optica.
Changes in our genes affect health risks from heart disease to cancer, but how those genes are turned on and off is just as crucial to health. What's more, almost all genes occur as two copies—one from each parent—that aren't necessarily turned on and off in sync. When that differential gene regulation goes awry, it can cause serious health problems.
Neutrinos come in three different flavors. A new study finds that neutrino flavor could play a significant role in whether a dying star becomes a supernova or collapses directly into a black hole.

Astronomers have discovered a star being torn apart by a massive black hole more than 1,000 parsecs from the center of its host galaxy. The tidal disruption event, TDE 2023mfm, was first discovered by ZTF and then studied with a wide range of telescopes, including Keck, Lick, Hubble, Swift, Chandra, XMM-Newton and the VLA. The discovery paper was posted to the arXiv preprint server on Sept. 28.
Scientists have discovered that black holes of vastly different sizes appear to launch powerful jets according to the same universal rule. The breakthrough could explain why some black holes suddenly erupt years after devouring a star and help astronomers predict when these spectacular outbursts will happen.
Scientists discovered that atomic steps just one atom high can guide quantum vortices through superconductors, making them move more than 1,000 times more easily in one direction than another. This remarkable control over quantum motion could lead to a new generation of ultra-efficient superconducting electronics.
Glimpses of the "gallium anomaly" were first seen in the mid-1990s, but it was first clearly discovered and stated in 2007 by neutrino physicist Carlo Giunti of Italy. The problem is simple to state but potentially very important: about 20% fewer electron neutrinos were seen to be captured by gallium nuclei than expected.

New materials and catalysts have the potential to transform everything from food production and medicine to batteries and stainless steel. Computer simulations help scientists narrow down promising candidates before testing them in a lab, but those simulations can be unreliable, especially for molecules that contain multiple metals.
Humanity's ongoing disruption of atmospheric carbon dioxide (CO₂) concentrations, temperatures, and global nutrient cycles is starving the oceans of oxygen. Although we can measure ongoing changes to ocean circulation and marine life, we still don't know how far the oxygen loss and the damage to ocean ecosystems could go. One way to foresee the oceans' future is to look back at how our seas and their inhabitants responded to higher CO₂ levels and warmer climates in the past.
Silicon spin qubits are a promising platform for building scalable quantum computers as they are compatible with the semiconductor manufacturing technologies used to produce today's computer chips. However, they have an important weakness: silicon spin qubits typically lose accuracy when several qubits are under parallel control. To be useful, quantum computers will need to operate many qubits simultaneously without compromising the accuracy of their operations.
When corals are stressed by pollution, high water temperatures or other environmental changes, they can lose the microscopic algae living inside them and on which they depend for food. As a result, they turn white, a phenomenon known as coral bleaching. They will not die straight away, but it will be game over if the stress continues long enough for them to starve.
The work could help improve quantum computers’ accuracy in complex calculations
Physicists at Auburn University have used flashes of laser light to bring order to tiny electrically charged "islands" inside a crystal.

Einstein's theory of general relativity describes gravity as the bending of spacetime, a mathematical model that combines three-dimensional space and time into a single, four-dimensional continuum. The theory also predicts that a rotating object, such as Earth, slightly drags the surrounding spacetime as it rotates, a phenomenon known as frame-dragging.

Fine particulate matter consists of tiny particles with diameters in the nanometer range. They are produced, for example, by fuel combustion, remain suspended in the air and can penetrate deep into the respiratory tract. There, they can trigger oxidative stress, a process that promotes inflammation and, over the long term, can lead to serious health problems such as respiratory or cardiovascular diseases. Scientists call this harmful property the particles' oxidative potential.

Researchers at Friedrich Schiller University Jena and the University of Regensburg have developed a method for determining, using light, a quantum property of electrons that has hitherto been difficult to access. The focus is on what is known as Berry curvature—a quantity that describes certain geometric properties of the quantum mechanical states of electrons. The researchers measured it in a layer of the semiconductor tungsten diselenide, just one atomic layer thick, using ultrashort laser pulses. The results have been published in the latest issue of the journal Nature Photonics.
Magnetic skyrmions (MSks) are swirling patterns of magnetization that form inside certain magnetic materials. They can behave like actual particles in many ways, exhibiting a stable internal structure and distinct boundaries. Because they are extremely small and can be pushed around with relatively little energy, MSks are regarded as promising information carriers in emerging technologies, including low-power memories and logic circuits. However, a major goal in the field has been to find practical ways to control their motion with high precision.
A faster way of finding the best diamond-based materials for quantum computers has been developed by a researcher at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL). The new approach has already identified promising materials for practical quantum sensors and computers that could one day transform scientific research as a whole. The research was recently published in the journal ACS Central Science and has already garnered attention from other experts in the field.
For decades, physicists have sought a practical two-dimensional topological insulator: an ultrathin material whose interior blocks electricity but whose edges conduct it. In ordinary wires, electrons constantly bounce off imperfections, losing energy. But along the edges of a 2D topological insulator, electrons with opposite spins travel in opposite directions, like cars in one-way lanes, so they rarely scatter and lose energy.
A concept from the field of quantum mechanics, spin is a property of particles that has no direct counterpart in everyday experience. Since the early 20th century, researchers have learned to manipulate it deliberately by means of precisely shaped electromagnetic pulses. This has resulted in two technologies that are widespread today: magnetic resonance imaging (MRI) is commonplace in hospitals, and nuclear magnetic resonance spectroscopy (NMR) is used to determine the structures of proteins and to develop new drugs. The mathematical framework of optimal control theory can be used to improve these technologies.
When drugmakers want to improve on compounds they have already created, they can replace a carbon atom with a nitrogen atom. While effective, the techniques they use to perform this chemical swap, known as skeletal editing, have some downsides. For example, older approaches often require harsh chemicals or only work on specific types of molecules.

When we think about a diamond, we often think about a material whose value comes from its perfection.

The challenge is learning how to control these defects without disturbing the others.
