Phys.org / Overlooked threat: Dams trigger temperature-driven disease in iconic salmonid fish
A new study published in Communications Biology reveals a critical, yet previously overlooked, environmental consequence of man-made dams constructed across rivers and streams. By investigating a key indicator species of ...
Tech Xplore / As fossil fuel use declines, experts urge planning and coordination to prevent chaotic collapse
As the world shifts toward renewable energy sources, some experts warn that a lack of planning for the retirement of fossil fuels could lead to a disorderly and dangerous collapse of existing systems that could prolong the ...
Phys.org / Laser beam flips a ferromagnet's polarity without heating the material
Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create adaptable electronic circuits ...
Phys.org / Gold 'supraballs' nearly double solar energy absorption in tests
Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn't capture as much as it could. Now, in ACS Applied Materials & Interfaces, researchers report that gold nanospheres, named supraballs, ...
Medical Xpress / How the brain's 'memory replay' goes wrong in Alzheimer's disease
Memory dysfunction in Alzheimer's disease may be linked to impairment in how the brain replays our recent experiences while we are resting, according to a new study in mice by University College London (UCL) scientists. The ...
Medical Xpress / The statin gap: Survey reveals many Americans are unaware of life-saving cholesterol alternatives
Unhealthy cholesterol levels are a major risk factor for heart disease and stroke. When lifestyle changes like diet and exercise aren't enough to lower cholesterol, medications can help. A new national survey commissioned ...
Medical Xpress / Fruit fly 'Fox' neurons show how brains assign value to food
Why do we sometimes keep eating even when we're full and other times turn down food completely? Why do we crave salty things at certain times, and sweets at other times? The answers, according to new neuroscience research ...
Phys.org / How a superionic state enables long-term water storage in Earth's interior
The cycling of water within Earth's interior regulates plate tectonics, volcanism, ocean volume, and climate stability, making it central to the planet's long-term evolution and habitability and a key scientific question. ...
Phys.org / NASA telescopes spot surprisingly mature cluster in the early universe
Astronomers at The University of Manchester have played a leading role in the discovery of a new cosmic object that is much larger than anything astronomers have seen before in the distant universe. This new discovery captures ...
Medical Xpress / Vaping zebrafish suggest e-cigarette exposure disrupts gut microbial networks and neurobehavior
Electronic cigarettes (e-cigarettes), widely marketed as a safer alternative to traditional cigarettes, are now hooking younger generations. World Health Organization data from 2025 show that at least 15 million adolescents ...
Phys.org / CERN chief upbeat on funding for new particle collider
Mark Thomson, the new head of Europe's physics laboratory CERN, voiced confidence Tuesday about raising the billions of dollars needed to build by far the world's biggest particle accelerator.
Medical Xpress / Diagnosis of cardiomyopathy is on the rise in Sweden
The number of patients diagnosed with cardiomyopathy has increased substantially over the past two decades. This is the finding of a new study from Uppsala University that mapped all cases of cardiomyopathy in Sweden. Despite ...
