Filming ICE is legal but exposes you to digital tracking. Here's how to minimize the risk

Phys.org 

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?

Scientists design molecules 'backward' to speed up discovery

Phys.org 

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.

Q&A: Wildfire in protected Northwest forests highlights need for strategy updates

Phys.org 

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.



Chiral phonons create orbital current via their own magnetism

Phys.org 

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.

Grains of sand prove people—not glaciers—transported Stonehenge rocks

Phys.org 

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.

Rushing a major strategy announcement can be a mistake for new CEOs

Phys.org 

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.

World's first high-resolution global leaf chlorophyll map can closely track plant health

Phys.org 

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.

Key protein can restore aging neural stem cells' ability to regenerate

Phys.org 

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.

Largest canine gut microbiome catalog reveals hundreds of new bacterial strains

Phys.org 

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.

How European city life is continually rewriting insect DNA

Phys.org 

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.

Velocity gradients prove key to explaining large-scale magnetic field structure

Phys.org 

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.

2.6-million-year-old Paranthropus fossil expands early hominin range

Phys.org 

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.

Quantum-enabled proteins open a new frontier in biotechnology

Phys.org 

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.
