Phys.org / Evidence of cosmic-ray acceleration from a nearby supernova remnant
Cosmic rays seen at Earth show a wide range of particle energies, from 107 electron-volts (eV) to more than 1020 eV, the latter being about the same as the kinetic energy of a 450 gram football (soccer ball) being kicked ...
Phys.org / Pulsar wind nebula inside supernova remnant explored with Chandra
Astronomers from the George Washington University (GWU) in Washington, DC, and elsewhere have employed NASA's Chandra X-ray spacecraft to observe a pulsar wind nebula inside a supernova remnant known as CTA 1. Results of ...
Phys.org / Survey shows little shift in Americans' views on political violence
A large, nationally representative survey of U.S. adults finds that support for, and willingness to engage in, political violence remained largely stable from mid-2024 to mid-2025, despite a highly contentious national election ...
Phys.org / IceCube detects break in cosmic neutrino spectrum, ruling out simple power-law model
A new study published in Physical Review Letters by the IceCube Collaboration reports evidence that the energy spectrum of astrophysical neutrinos is not a simple straight line.
Phys.org / Famous wildlife coexistence scheme is slipping due to frozen funding
A celebrated scheme for human-wildlife coexistence is now at risk of failing due to lack of long-term government investment, new research has found.
Phys.org / Precise polymer 'knots' uncover hidden slack for designing ultra-tough and responsive smart materials
From household plastic packaging to the flexible frameworks that support wearable electronics, polymer materials form the invisible backbone of modern life. At a microscopic level, polymers consist of long, ribbon-like molecular ...
Medical Xpress / Magnetic particle imaging may help tailor cell therapy delivery, mouse study suggests
Scientists at Johns Hopkins Medicine say they used a form of magnetic imaging to track cell therapy injections commonly used to treat certain autoimmune diseases and cancers. The findings, from a study of mice, add to a growing ...
Medical Xpress / Children's brain tumors may spread faster when microglia build invasion-friendly scaffolding
Researchers at the Institute of Environmental Medicine (IMM), Karolinska Institutet, have identified a possible mechanism behind the spread of the aggressive brain tumor diffuse midline glioma. The study shows that the brain's ...
Medical Xpress / Tiny brain probe reveals how deep-brain neurons can be measured and manipulated
A new breakthrough technology, co-developed by UCL scientists, that simultaneously records and manipulates neuron activity deep within the brain could transform our understanding of neural circuits and neurological conditions, ...
Science X / When Earth went dark after Chicxulub, tiny ocean dwellers held the secret to survival
When a 10-kilometer asteroid struck Earth 66 million years ago, the planet was plunged into darkness—and about 75% of species vanished, including marine life. Now, a new study reveals that the planetary effects from the impact ...
Medical Xpress / Baby brain myth fades as 300 new parents match non-parents on cognition
The largest and most comprehensive study of memory and cognition in new parents has found no evidence for "baby brain" in mums and dads. New mums often complain about having "baby brain," where memory and cognition become ...
Medical Xpress / National index tracks AI health care regulations as policy patchwork grows
As artificial intelligence rapidly enters health care, policymakers and health systems are struggling to keep pace with the implications for how the technology should be governed to ensure patient safety, provider accountability, ...
