Dialog / Amazon fish contaminated with toxic metals threaten riverine communities' health
For riverside communities along the Amazon, fish is not a menu choice—it is a lifeline. Millions of people in the Brazilian Amazon depend on fish as their primary source of protein, consuming it daily in quantities far ...
Phys.org / Multifractal patterns across deep time: What measurement density reveals about Earth's history
Much of our understanding of Earth's past is derived from stratigraphic records exposed in rock outcrops or recovered from drilled cores. These records span immense time intervals, from thousands to billions of years, and ...
Phys.org / AI-designed diffractive optical processors pave the way for low-power structural health monitoring
A team of researchers at the University of California, Los Angeles (UCLA) has introduced a novel framework for monitoring structural vibrations using diffractive optical processors. This new technology uses artificial intelligence ...
Phys.org / Shrinking the carbon footprint of chemical manufacturing with lasers and solar radiation
Researchers have found a way to use solar energy to power a key chemical reaction that drives many manufacturing industries. This new method can significantly reduce the energy required to run these operations, eliminate ...
Phys.org / Protecting wildlife from genetic collapse with newly identified 'early warning signals'
A new study reveals that habitat fragmentation can lead to sudden "tipping points" where a species' genetic health unexpectedly collapses after appearing stable for long periods. By merging network theory with population ...
Phys.org / Polymers that crawl like worms: How materials can develop direction without being told where to go
Researchers at the University of Vienna have uncovered a surprising phenomenon: polymer chains with segments that simply fluctuate at different intensities can spontaneously develop directional, persistent motion when densely ...
Phys.org / Drones capture rare harbor porpoise mating behavior off Shetland
Drones flying above the waters of Shetland have captured rare footage of harbor porpoises gathering in unusually large groups and engaging in mating behavior. The footage, gathered between 2019 and 2023, provides one of the ...
Phys.org / 3D imagery helps bring world's ant diversity to life
For more than a decade, Evan Economo's lab has been using micro-CT machines to scan insect specimens. The resulting X-ray images help researchers study the form and structure of insects—a subfield of entomology known as ...
Phys.org / ESA's Mars orbiters watch solar superstorm hit the red planet
What happens when a solar superstorm hits Mars? Thanks to the European Space Agency's Mars orbiters, we now know: glitching spacecraft and a supercharged upper atmosphere.
Phys.org / Tracking the toxic metals left behind by wildfires
Between 2023 and 2025, more than 30 million hectares burned in Canada due to wildfires. The threat from increasingly frequent and intense wildfires goes beyond fire and smoke—the heat can also transform naturally occurring ...
Phys.org / How evolution shapes color diversity in coral reef fish
Why does a Caribbean angelfish sometimes resemble its Indo-Pacific cousin, even though they have never lived in the same ocean? Why do coral reefs harbor such a wide range of stripes, spots and patterns? A study conducted ...
Phys.org / Ocean currents drive disease spread between oyster reefs: Research identifies restoration sites at risk
The European flat oyster (Ostrea edulis) was once widespread in the North Sea. However, overfishing, habitat destruction and infectious diseases pushed the species to the brink of extinction in some regions nearly one hundred ...
