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 / 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 / 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 / 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 / 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 / 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 ...
Phys.org / Burned permafrost peatlands release carbon for years after wildfires, researchers find
In the face of climate change, permafrost peatland wildfires could play more of a role in the destructive cycle of global warming, University of Alberta research suggests.
Phys.org / Real-time imaging of microplastics in the body improves understanding of health risks
Microplastics (MPs), defined as plastic fragments with sizes ranging from millimeters (
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 / The secret lives of catalysts: How microscopic networks power reactions
Catalysts are essential to modern industry, accelerating reactions used to produce everything from fertilizers and fuels to medicines and hydrogen energy. But until now, scientists could not directly observe how reactions ...
Phys.org / Paleontologists challenge use of bone growth rings to age crocodiles, dinosaurs
Do the bones of all Nile crocodiles have the same number of growth marks as their age? And can such growth rings be counted to accurately gauge the age of these reptiles? Is this also an accurate method to use when trying ...
