When an Immigration and Customs Enforcement agent shot and killed Renee Nicole Good in south Minneapolis on Jan. 7, 2026, what happened next looked familiar, at least on the surface. Within hours, cellphone footage spread online and eyewitness accounts contradicted official statements, while video analysts slowed the clip down frame by frame to answer a basic question: Did she pose the threat federal officials claimed?

In a week filled with news about President Donald Trump's aggressive moves to take control of Greenland, the world got a window into his thinking about the concept of "peace."

The UK government has launched a consultation on introducing an Australian-style ban on social media for under-16s. The proposal is framed as a bold response to rising concerns about young people's mental health, online abuse and exposure to harmful content.

The rapid growth of artificial intelligence has sharply increased electricity and water consumption, raising concerns about the technology's environmental footprint and carbon emissions. But the story is more complicated than that.

Scientists from the National University of Singapore (NUS) have discovered that atomic-scale substitutional dopants in ultra-thin two-dimensional (2D) materials can act as stable quantum systems operating at terahertz (THz) frequencies.

Every medication in your cabinet, every material in your phone's battery, and virtually every compound that makes modern life work started as a molecular guess, with scientists hypothesizing that a particular arrangement of atoms might do something useful—kill a bacterial infection, store electrical charge, or absorb sunlight efficiently.

U.S. forests have stored more carbon in the past two decades than at any time in the last century, an increase attributable to a mix of natural factors and human activity, finds a new study.

The Northwest Forest Plan, adopted in 1994, helped quell mounting tensions between timber companies and environmentalists. It protected large swaths of old-growth forest in Washington, Oregon and California to preserve habitat for endangered species, including the Northern spotted owl and marbled murrelet.

Human activity continues to expand ever further into wild areas, throwing ecology out of balance. But what begins as an environmental issue often evolves into a human problem.

In a new study, an international group of researchers has found that chiral phonons can create orbital current without needing magnetic elements—in part because chiral phonons have their own magnetic moments. Additionally, this effect can be achieved in common crystal materials. The work has potential for the development of less expensive, energy-efficient orbitronic devices for use in a wide array of electronics.

Ask people how Stonehenge was built and you'll hear stories of sledges, ropes, boats and sheer human determination to haul stones from across Britain to Salisbury Plain, in south-west England. Others might mention giants, wizards, or alien assistance to explain the transport of Stonehenge's stones, which come from as far as Wales and Scotland.

New research into the impact of climate change on snow sports provides recommendations to increase the climate-resilience of the Olympic and Paralympic Winter Games.

When a new CEO takes over at a firm, it creates uncertainty for important stock market participants such as financial analysts who meet regularly with them and influence the investing patterns for the world's largest institutional investors. They wait eagerly for the new leader to reveal their first major strategy and the future direction of the firm.

A research group has achieved a new plasma confinement regime using small 3D magnetic perturbations that simultaneously suppress edge instabilities and enhance core plasma confinement in the Experimental Advanced Superconducting Tokamak (EAST). The research results are published in PRX Energy.

A research team led by Profs. Li Jing and Liu Qinhuo from the Aerospace Information Research Institute of the Chinese Academy of Sciences (AIRCAS) has developed the world's first global, high-resolution map of leaf chlorophyll content (LCC), providing a new method for closely tracking plant health and ecosystem productivity worldwide. The study was recently published in Scientific Data.

Researchers at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), have found that a key protein can help to regenerate neural stem cells, which may improve aging-associated decline in neuronal production of an aging brain.

Researchers at the Waltham Petcare Science Institute in the UK recently revealed a complete taxonomic and functional catalog of the canine gut microbiome after analyzing samples from 107 healthy dogs across the U.S. and Europe. The study, published in the journal Microbiome, unveiled an array of new bacterial strains and their role in gut health. The resulting catalog is now the most comprehensive resource for the gut microbiome in companion animal research.

Cities are known to shape the evolution of wildlife within them, but according to a study of European cities published in the journal Proceedings of the Royal Society B: Biological Sciences, this is not a one-off event. Rather than a single urban genotype of a species spreading from one place to another, scientists found that evolution often starts from scratch, creating distinct genotypes in different cities.

A hand stencil on the wall of a cave in Indonesia has become the oldest known rock art in the world, exceeding the archaeologists' previous discovery in the same region by 15,000 years or more.

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the solar wind, high-energy particle transport, and galaxy formation. Small-scale magnetic fields are generally turbulent and chaotic, yet large-scale fields are organized, a phenomenon that plasma astrophysicists have tried explaining for decades, unsuccessfully.

Neural tissue normally dies quickly without oxygen. Yet bird retinas—among the most energy-demanding tissues in the animal kingdom—function permanently without it. This may be relevant in future treatment of stroke patients.

During the last ice age, the Atlantic Ocean's powerful current system remained active and continued to transport warm, salty water from the tropics to the North Atlantic despite extensive ice cover across much of the Northern Hemisphere, finds new research led by UCL scientists.

In a paper published in Nature, a team led by University of Chicago paleoanthropologist Professor Zeresenay Alemseged reports the discovery of the first Paranthropus specimen from the Afar region of Ethiopia, 1,000 km north of the genus' previous northernmost occurrence.

A research team led by the University of Oxford's Department of Engineering Science has shown it is possible to engineer a quantum mechanical process inside proteins, opening the door to a new class of quantum-enabled biological technologies.

Imagine Max, a well-trained border collie, manages to ignore a squirrel in the park when his owner tells him to sit. His owner says, "Max, stop chasing that squirrel and sit down," and Max obeys. Can dogs learn and understand words the way humans do?
