Phys.org / What a dry meteorite tells us about water on Mars
Detecting water where none remains today: Neutron and X-ray tomography make it possible. In an international study conducted with the participation of the Paul Scherrer Institute PSI, researchers have brought to light macroscopic ...
Tech Xplore / Peering inside LLM-based multi-agent systems could expose stealthy attacks
Large language models (LLMs), the models that underpin platforms such as ChatGPT and Gemini, are now used daily by more than a billion people worldwide. Some computer scientists have also been combining several of these models ...
Medical Xpress / Astrocytes directly regulate brain circuits that consolidate memories during sleep, study reveals
Research has shown that a good night's sleep has many benefits, including memory consolidation. How sleep enables the brain to strengthen memories is still not completely understood, but a new study published in Neuron reveals ...
Phys.org / Oldest known giant rock scallop bead suggests California coastal trade began millennia earlier
Archaeologists have discovered two giant rock scallop beads that push back the clock on the first appearance of these high-status ornaments. The discovery shows that these prized marine beads were traded hundreds of miles ...
Phys.org / Magnetic mystery in thorium clusters resolved by new study
Scientists from the University of Manchester's Department of Chemistry, Centre for Radiochemistry Research and Photon Science Institute, led by Professor Steve Liddle, have uncovered why a rare class of metal clusters appears ...
Medical Xpress / Long before adulthood, a chemical mark may quietly shape how the brain handles stress
Stress or trauma during childhood may leave people more vulnerable to mental health struggles and stress later in life. Scientists think one reason could be that early-life stress leaves lasting molecular bookmarks on DNA, ...
Phys.org / Does your city match your relationship status? New study exposes the hidden costs of urban living
Kids, marriage and commute: A study co-authored by Dr. Mariana Macedo of Constructor University provides new insights into how major life transitions alter how individuals navigate and experience urban environments. Published ...

On a summer day in Michigan, a tiny Poweshiek skipperling butterfly—smaller than a quarter—takes flight over a restored prairie.
Medical Xpress / Arthritis origins may begin before birth
Researchers at the Kennedy Institute have discovered that some joints may be more susceptible to inflammatory arthritis before birth, offering new insight into why rheumatoid arthritis attacks particular joints while sparing ...
Phys.org / AI cyclone forecasts could add 30 hours of warning time
Tropical cyclones are among the most destructive natural forces on the planet, but predicting where they will go and how strong they will become is beset by challenges. Current methods are often good at tracking storm paths ...
Phys.org / Many US public parks sit surprisingly close to hazardous waste sites and facilities that release toxic chemicals
While parks, playgrounds and hiking trails are generally thought of as "healthy" spaces, researchers from the University of Michigan have found that many of them overlap with old toxic waste sites or sit dangerously close ...
Phys.org / Tracer exchange reveals ions can speed up or slow down inside battery solids
Understanding how ions diffuse in solid materials is essential for technologies including batteries, electronics and chemical catalysts, but it has been hard for a simple reason: the materials are solids.
