Phys.org / Snow is vital for the Pyrenees, and it's disappearing fast
Snow is a defining feature of mountain ranges, and of winter itself for much of the world. But beyond its scenic value, snow plays a vital role in mountain ecosystems, as well as a range of human socioeconomic activity, and ...
Phys.org / World's oldest rock art holds clues to early human migration to Australia
A hand stencil on the wall of a cave in Indonesia has become the oldest known rock art in the world, exceeding the archaeologists' previous discovery in the same region by 15,000 years or more.
Phys.org / Hubble tension: Primordial magnetic fields could resolve one of cosmology's biggest questions
A Simon Fraser University cosmologist believes his team's new research may bring them a step closer to cracking one of science's biggest questions—the Hubble tension.
Phys.org / ALMA reveals teenage years of new worlds
Astronomers have, for the first time, captured a detailed snapshot of planetary systems in an era long shrouded in mystery. The ALMA survey to Resolve exoKuiper belt Substructures (ARKS), using the Atacama Large Millimeter/submillimeter ...
Phys.org / Ancient CO₂ surge triggered widespread forest fires and erosion 56 million years ago
The climate warmed up almost as quickly 56 million years ago as it is doing now. When a huge amount of CO2 entered the atmosphere in a short period of time, it led to large-scale forest fires and erosion. Mei Nelissen, Ph.D. ...
Phys.org / Humans use local dialects to communicate with honeyguide birds, research shows
Researchers from the University of Cape Town (UCT), working with international collaborators, have shown that people in northern Mozambique use regionally distinct "dialects" when communicating with honeyguide birds, revealing ...
Phys.org / How much of 'us' is really 'us'?
Some time around 1683, amateur Dutch scientist Antonie van Leeuwenhoek scraped the plaque from between his teeth and peered at it through a home-made microscope.
Medical Xpress / Taking acetaminophen during pregnancy does not increase risk of autism, ADHD or intellectual disabilities
Taking acetaminophen during pregnancy does not increase the risk of autism, attention-deficit hyperactivity disorder (ADHD), or intellectual disability among children. That is according to the most rigorous analysis of the ...
Medical Xpress / Lewy body formation in Parkinson's disease: Scientists propose a new molecular roadmap
Proteins form the building blocks of life, but when they form unusual clumps inside the brain, they raise an alarm that something isn't right.
Phys.org / Understanding the unusual chirality-driven anomalous Hall effect via scattering theory
A new framework for understanding the nonmonotonic temperature dependence and sign reversal of the chirality-related anomalous Hall effect in highly conductive metals has been developed by scientists at Science Tokyo. This ...
Phys.org / Largest canine gut microbiome catalog reveals hundreds of new bacterial strains
Researchers at the Waltham Petcare Science Institute in the UK recently revealed a complete taxonomic and functional catalog of the canine gut microbiome after analyzing samples from 107 healthy dogs across the U.S. and Europe. ...
Phys.org / Fast fashion: Why changes in return policies don't do enough to address environmental damage
Online fashion retailer Asos recently introduced additional fees for customers who return lots of items, marking a significant shift in the fast fashion model that has relied on free, frictionless return policies as a key ...
