Phys.org / Early humans in South Africa were quarrying stone as far back as 220,000 years ago
As long as 220,000 years ago—far earlier than previously thought—people quarried rocks for their tools in places they specifically sought out. An international research team led by the University of Tübingen has demonstrated ...
Medical Xpress / GLP-1 agonist drugs show digestive side effects but may help fight infections
Originally developed to treat diabetes, a class of drugs known as glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are now stepping into the spotlight as weight loss drugs. A recent umbrella review draws attention to ...
Phys.org / Ghostly particles: Dark radiation may have masqueraded as neutrinos
New research suggests that neutrinos in the early universe may have transformed into a previously unknown form of radiation. A study from Washington University in St. Louis offers a new way to explain certain puzzling observations ...
Phys.org / More than a pretty picture, star-shaped nanomaterial changes energy storage
When created at the nanoscale, materials can resemble shapes like stars, rods or even pyramids. These particle shapes, also known as the morphologies of a solid, make for more than just interesting images under a microscope—they ...
Phys.org / A tiny detector for microwave photons could advance quantum tech
Detecting a single particle of light is hard; detecting a single microwave photon is even harder. Microwave photons, the tiny packets of electromagnetic radiation used in current technologies like Wi-Fi and radar, carry far ...
Phys.org / Polymers built inside the body through blood-catalyzed chemistry allow on-demand brain control
The 19th-century science fiction novel Frankenstein explores the idea of combining artificial materials with human body components, purely as a matter of imagination. Two centuries later, such concepts have become integral ...
Phys.org / New Artemis II 'Earthset' shot revisits Apollo 8's iconic 'Earthrise,' 57 years on
The Artemis II astronauts snapped a stunning shot of Earthset—the moment when Earth dips below the moon's horizon—on their long journey back home Tuesday after wrapping up a historic lunar flyby.
Phys.org / Born to roam, built for home: New genomic insights for snapper fisheries
Snapper are central to coastal life across southern Australia, supporting fisheries, local businesses, and regional tourism. New Flinders University research has found that although snapper populations across southern Australia ...
Phys.org / Artemis II crew breaks Apollo 13 record, reaching 252,760 miles from Earth
The four astronauts embarking on NASA's lunar flyby became on Monday the humans to travel farthest from our planet, as they begin documenting areas of the moon never before seen by the naked eye.
Phys.org / Hot-dry extremes could hit 28% of humanity five times more often by end of century
In their current state, climate policies around the world could leave a significant chunk of the global population exposed to simultaneous extreme heat and drought over five times more often by the end of this century than ...
Phys.org / Rich biodiversity found in Japan's deepest ocean trenches, including an unidentified 'mystery' species
A new study published in the Biodiversity Data Journal provides a profound look at life up to nearly 10 kilometers below the ocean's surface in the Japan, Ryukyu, and Izu-Ogasawara trenches. The research catalogs at least ...
Phys.org / Ranks of Disparity: New approach fixes flaw in fairness algorithms
As organizations increasingly rely on algorithms to rank candidates for jobs, university spots, and financial services, a new method, named hyperFA*IR, offers a more principled approach when picking candidates based on a ...
