Economic hardship tied to increased violence across California‎

Economic instability—including job loss, food insecurity, eviction and homelessness—is strongly associated with higher rates of violence among California adults, according to a new statewide survey led by the University of California San Diego. The findings come from the 2025 California Violence Experiences Survey (CalVEX). The new report provides a comprehensive picture of how violence is experienced across the state, including forms of violence that often go unreported in official data.

How microplastics hurt the species that keep our coasts healthy‎

Walk across a mudflat at low tide and you might notice small, neat mounds of sediment scattered across the surface.

Unlocking the value of biodiversity in the UK and Ireland‎

Sequencing the DNA of all complex life in the UK and Ireland could generate up to almost £3 billion for the economy across agriculture, conservation, and research over the next 30 years, according to a new report.

Quantum-inspired algorithm solves 268 million-site quasicrystal simulation in a heartbeat‎

Quantum technologies like quantum computers are built from quantum materials. These types of materials exhibit quantum properties when exposed to the right conditions. Curiously, engineers can also trigger quantum behavior by manipulating a material's structure; for example, by stacking layers of graphene on top of each other and twisting them to create a moiré pattern, which suddenly turns them into a superconductor.

Gravity follows Newton and Einstein's rules, even at cosmic scales‎

Gravity, as most people understand it, is the familiar force that pulls a falling apple toward Earth. But for astronomers and theoretical physicists, it is also a vexing invisible architect that guides the shape and evolution of the largest cosmic structures across the universe.

Crowd flow measurements reveal hidden slowdowns and standstills in dense public spaces‎

How can public spaces remain safe when large crowds move through them? Engineers and researchers who study these environments often rely on physical models borrowed from fluid dynamics—a branch of physics that describes the collective motion of fluids, whose behavior emerges from the interactions of many particles. But a new study published in the Journal of Statistical Physics: Theory and Experiment highlights a crucial issue: The way data are collected and measured within these models lacks standardization and may overlook important features of human collective behavior. Unlike particles, people are living agents with individual decisions and complex interactions, making their movement harder to capture with traditional approaches.

Next-generation CT scanner reveal new details inside 2,300-year-old Egyptian mummy remains‎

Egyptian mummy remains were examined at Semmelweis University's Medical Imaging Center (OKK). The archaeological finds arriving from the Semmelweis Museum of Medical History, Hungarian National Museum Public Collection Center (MNMKK) were analyzed using the institution's newest CT scanner equipped with a photon-counting detector. Thanks to state-of-the-art imaging technology, highly detailed images have been captured that were previously unavailable, and the initial results promise significant scientific advances.

'Interstellar glaciers': NASA's SPHEREx maps vast galactic ice regions‎

NASA's SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) mission has mapped interstellar ice at an unprecedented scale. Covering regions in our Milky Way galaxy more than 600 light-years across, the ice was found inside giant molecular clouds—vast regions of gas and dust where dense clumps of matter collapse under gravity, giving birth to stars. A study describing these findings was published Wednesday in The Astrophysical Journal.

The giants of the reef: New citizen science project races to document centennial corals‎

Coral reefs hide "scientific treasures" that have survived for centuries, yet many of these giant, ancient organisms remain largely unknown to science. A new study published in the journal Nature Conservation introduces "Map the Giants," a pioneering citizen-science initiative launched by researchers from the University of Milano-Bicocca to find these giant coral colonies before they are lost to escalating global pressures.

Shakespeare's 'missing' London house mapped with new discovery‎

The exact location of William Shakespeare's only London property can now be pinpointed to a quiet Blackfriars street, thanks to the discovery of a previously unknown floorplan. The discovery, made by Shakespeare expert Professor Lucy Munro from King's College London, not only identifies the exact place of the property Shakespeare bought in 1613 but also the layout and size. It also paints a different picture of where Shakespeare may have spent some of his time in his later years.
