For the first time, physicists have demonstrated that a material’s superconductivity can be altered by coupling it to an in-built, light-confining cavity. In experiments published in Nature, a team led by Itai Keren at Columbia University show how quantum properties can be deliberately engineered by bonding carefully chosen materials together—without applying any external light, pressure, or magne

Local recreation areas play an important role in reducing stress. In two new publications, researchers at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL show how visual impressions and sounds interact in this process—and how this knowledge can be used to increase the attractiveness of green spaces.

Roughly 425 million years ago, in the warm seas over what is now southern China, there lived a meter-long bony fish with jaws full of clusters of spiky teeth.

In physics, the mesoscale lies between the microscopic and the macroscopic. It is not just the domain of tiny living creatures like small larvae, shrimp, and jellyfish, but also where physics equations become extreme. While the macroscopic realm is governed by inertia and the microscopic by viscosity, the mesoscale is both and neither, requiring a new set of physics to describe it.

Nonsense-mediated mRNA decay (NMD) is one of the most important processes in our cells to ensure that no faulty or incomplete proteins are produced. Scientists have now identified a central mechanism behind this control system.

Evidence suggests that China’s “cradle of civilization” experienced marked climate disasters and social upheavals during the mid-late Holocene (around 3,000 years ago). However, the direct causes and impacts of these ancient inland disasters were unclear. In a new study, published in Science Advances, a team of Chinese researchers points to intensified typhoon activities during this time as a main

Payments that enable landowners to rewild ecologically degraded land—in the form of biodiversity credits bought by investors wishing to offset their impact on nature—could be an effective component of the emerging market for nature recovery, but will not work as a standalone approach.

The electronic and magnetic properties of two-dimensional materials both have strong potential for technological applications. Researchers have long assumed that they are distinct phenomena, but Illinois Grainger engineers have demonstrated that they share a mathematical language.

Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical sources at the single-photon level. Published in Nature, a team led by Pieter-Jan Stas at Harvard University showed how extremely weak light signals could be detected across a fiber link spanning more than 1.5 km—possibly paving the way for optical telescopes with unprecedente

The Doomsday Clock—a symbolic device to signal an array of existential threats to the world since 1947—was recently moved to 85 seconds before midnight, the closest it has ever been to midnight. And that was before all-out war broke out in Iran.

At some point, most people have found themselves holding a tilted carton of milk or bottle of cooking oil, patiently waiting for the last drops to drip out. Now, physicists at Brown University have done the math to show just how long you might have to wait.

Europe is struggling more and more with extreme heat in the summer. While climate change is the main reason for this increase, what specific physical mechanisms cause a heat wave? One important driver of weather conditions in Europe is the North Atlantic. For example, studies by the Max Planck Institute for Meteorology (MPI-M) have shown that heat build-up in the subtropical North Atlantic can lea

Long-term ecosystem warming changes not only plants but the fungi in the soil below, according to a new study including researchers from the University of Tennessee, Knoxville. “Hidden mycorrhizal fungi below ground are much more vulnerable to warming winters than we expected before,” said Associate Professor Stephanie Kivlin from UT’s Department of Ecology and Evolutionary Biology, senior author

Artificial intelligence (AI) is transforming the way scientists discover and design new materials. In a specially invited review published in Angewandte Chemie International Edition, Tohoku University researchers highlight how large AI models are redefining catalyst discovery and paving the way for faster, smarter innovation in clean energy and sustainable technologies.

Red dwarfs make up the vast majority of stars in the galaxy. Such ubiquity means they host the majority of rocky exoplanets we’ve found so far—which in turn makes them interesting for astrobiological surveys. However, there’s a catch—astrobiologists aren’t sure the light from these stars can actually support oxygen-producing life. A new paper, available on the arXiv preprint server, by Giovanni Co

A new study from the University of Helsinki reveals how plant mitochondria draw molecular oxygen away from chloroplasts, an interaction not previously documented. The discovery sheds new light on how plants regulate oxygen inside their tissues, with implications for understanding plant metabolism and stress acclimation. The research, led by Dr. Alexey Shapiguzov (Ph.D., Docent) from the University

The Environment Agency and the University of Stirling have published a new report on the links between phosphorus concentrations and ecology in English rivers. Phosphorus remains one of the most significant pollutants in England’s rivers. In recent decades, the overall concentration of phosphorus in English rivers has declined, most likely due to the introduction of phosphorus removal technologies

Life’s capacity to survive in simulated lunar and Martian soils has been explored in two papers published in Scientific Reports. Treating simulated lunar soil with both symbiotic fungi and worm-produced compost can significantly improve the likelihood of reproduction for chickpea plants growing in the soil, indicates one study. A separate paper suggests that some microbes may be able to absorb eno

Superconductivity is a quantum state of matter characterized by an electrical resistance of zero and the expulsion of magnetic fields at low temperatures below a critical point. Superconductors, materials in which this state occurs, have proved to be highly advantageous for the development of various technologies, including medical imaging devices, particle accelerators and quantum computers.

Ever since physicist Freeman Dyson first proposed the concept in 1960, the “Dyson sphere” has been the holy grail of techno-signature hunters. A highly advanced civilization could build a “sphere” (or, in our more modern understanding, a “swarm” of smaller components) around their host star to harvest its entire energy output. We know, in theory at least, that such a swarm could exist—but what wou

Honeybees collecting nectar from a “buffet” of Australian native plants made honey with anti-microbial abilities that is more potent than “single origin” honey made from only one source of plant or flower, a University of Sydney-led study has found.

Every time we feel a gentle tap on the skin, specialized nerve cells convert that physical force into an electrical signal the brain can interpret as touch. While scientists have long known that a protein called PIEZO2 acts as a key sensor for touch, it remained unclear why PIEZO2 is specialized for the localized mechanical forces experienced by sensory neurons, whereas its close relative PIEZO1 r
