Layered ZnPS₃ emits single photons, opening new path for quantum chips‎

Scientists from the Faculty of Physics at the University of Warsaw, in collaboration with teams from the National University of Singapore and Radboud University in the Netherlands, have observed single-photon emission from layered two-dimensional material ZnPS₃. This discovery represents a crucial step toward establishing low-dimensional materials as a versatile platform for quantum information science. The research findings were published in the journal ACS Nano.

One‑step process generates high entropy alloy nanoparticles in milliseconds for catalyst creation‎

A University at Buffalo-led team of researchers has developed a method for producing advanced nanoparticles that could accelerate the discovery of new materials for energy and electronic applications. The study, published in Nature Communications, introduces a one-step process that rapidly combines multiple metals into uniform nanoparticles in milliseconds. This allows researchers to quickly produce and explore a wider range of material combinations than was previously possible.

Medici brothers' remains reveal Renaissance-era malaria strains, closing the book on a murder mystery‎

In 1562, Cardinal Giovanni de Medici, a scion of the dynastic family that dominated politics and banking in Tuscany during the Renaissance, died of malaria. Twenty-five years later, his older brother, Grand Duke Francesco de Medici, succumbed to the same disease.

Super-deep diamond discovery may rewrite Earth's role in preserving the building blocks of life‎

Two diamonds formed 700 kilometers below the Earth's surface reveal a life-giving synchronicity between shifting continents and the cycling of phosphorus, a vital building block of DNA and cell membranes.

Extreme droughts in the rainforest reduce important feedback between soil and atmosphere, study finds‎

Isoprene is a volatile organic compound (VOC) that is produced naturally by plants. More than 500 megatonnes of isoprene are emitted each year into Earth's atmosphere, primarily from tropical forests. Soils are recognized sinks for atmospheric isoprene, but their behavior in natural environments remains poorly understood, particularly in the Amazon, where emissions are globally significant.

Mice actively seek better views to make visual decisions, virtual reality experiments show‎

Animals don't experience the world passively. A hawk tilts its head to track prey. A person leans forward to read a sign. Scientists call this "active sensing": moving the body to gather better information. A specific version of active sensing is infotaxis, which describes how animals move strategically to maximize the information they gain from their surroundings. Whether mice use this strategy has remained an open question, despite their central role in neuroscience research.

Sound waves reconstruct Alaska fireball path after cameras miss key details‎

When a bright fireball streaked across the Alaska sky last spring, the usual tools scientists rely on to track such events—cameras and satellites—did not provide a detailed picture. But the meteoroid left behind something else: low-frequency sound waves that traveled hundreds of miles and were captured by a dense network of earthquake and volcano-monitoring sensors on the ground.
