Phys.org / Burned-home soils showed uneven lead, arsenic contamination after Los Angeles wildfires
A chemical analysis of residential soils and ash around California homes burned by the Eaton and Palisades wildfires in early 2025 revealed wide variation in contamination by potentially harmful elements, including lead, ...
Phys.org / New research identifies types of dishonesty that occur in a relationship—and their consequences
From "harmless" white lies to infidelity, dishonesty in romantic relationships is a complex phenomenon that takes on many forms. New research from the University of Copenhagen shows that while dishonesty between partners ...
Phys.org / World's largest particle smasher halts for upgrade to boost hunt for dark matter
The world's most powerful particle accelerator will shutter operations Monday for four years of renovations to dramatically boost its collision capacity and the potential for unlocking one of the greatest mysteries of the ...
Medical Xpress / Scratching that bug bite might feel good at first but science explains why it's a bad idea
You've likely heard it since childhood: Don't scratch that bug bite or rash, you'll make it worse. But why would something that feels so good be bad?
Medical Xpress / Researchers develop HIV-prevention guide without the stigma of asking about risk
The most useful thing about a new HIV prevention guide may be a question it never asks: Why do you want to know about pre-exposure prophylaxis, or PrEP? In a pilot study at three clinics, a two-page decision aid helped people ...
Phys.org / New millisecond pulsar discovered with the Murchison Widefield Array
Using the Murchison Widefield Array (MWA), astronomers have discovered a new millisecond pulsar as part of the ongoing Southern-sky MWA Rapid Two-metre (SMART) survey. The discovery is reported in a research paper published ...
Phys.org / Primate evolution kept aging rates stable for 25 million years despite lifespan gaps
Biologists group animals with similar traits into broad categories called orders. Despite their similarities, animal species in the same order can have very different average lifespans.
Phys.org / The bond between humans and dogs remains remarkably consistent across societies, cross-cultural study reveals
A new study by an international research team led by Friedrich Schiller University Jena and the Max Planck Institute for Evolutionary Anthropology (Leipzig) has revealed striking similarities in the way humans and dogs interact ...
Phys.org / Newly identified fossil sheds light on evolutionary history of saber-toothed cats
Fossils tucked away in a museum drawer and identified merely as "feline" are actually from a very ancient and enigmatic saber-toothed cat that inhabited North America more than 5 million years ago. Newly identified by a UC ...
Medical Xpress / Large MRI analysis uncovers brain-region thinning tied to depression
Major depressive disorder (MDD) is a psychiatric condition characterized by persistent feelings of sadness, a loss of interest in everyday activities, altered sleeping and/or eating patterns, low energy, and difficulty concentrating ...
Phys.org / Lithium-doped carbon nanorings show promise for next-generation optical devices
Nonlinear optical materials are essential for advanced photonics and laser technologies, but researchers are still searching for ways to optimize organic, carbon-based alternatives. Using computational modeling, scientists ...
Phys.org / Coastal and estuarine carbon removal technique may backfire when pushed too far
Scientists investigating a proposed way to remove carbon dioxide from the atmosphere using seawater have found that adding too much alkalinity to neutralize acids can trigger chemical reactions that undermine the process.
