Science X / Beneath pale ash, a quantum microscope reveals hidden traces of Neanderthal fire use preserved for millennia
An ancient hearth at El Salt (Spain) is giving up its secrets—not with flames, but with physics. Scientists have already established that Neanderthals used to make fires at this site (spanning from 80,000–45,000 years ago), ...
Phys.org / Scabies can kill animals like the beloved wombat. What's the best way to diagnose it?
Constant scratching, bumpy skin and tufts of lost fur. Those are just some of the signs that an animal has scabies, a severe and potentially fatal skin disease caused by tiny mites (Sarcoptes scabiei) that burrow into the ...
Phys.org / Highly tunable electro-optic isolator achieves one-way light flow on photonic chips
Integrated photonic devices—tiny circuits that use light instead of electrons—are becoming increasingly important for scalable photonics technologies and high-bandwidth communications. They are particularly valuable for managing ...
Phys.org / Saber-toothed cats' spinal tumors suggest inbred species struggled to survive
The fossilized spines of saber-toothed cats in the La Brea Tar Pits reveal evidence of an unexpectedly high prevalence of rare spinal nerve tumors, suggesting that the species became inbred just before extinction. These tumors, ...
Medical Xpress / New wearable ring tracks glucose, ketone and other biomarkers in sweat simultaneously
Engineers at the University of California San Diego created a smart ring that simultaneously and continuously monitors up to four different chemical biomarkers from finger sweat. The biomarkers the smart ring can monitor ...
Phys.org / Scientists cut and rebuild molecules from the inside to create new chiral nanocarbons
Nanocarbons are molecular-scale carbon structures considered to be the building blocks for next-generation materials. Until now, scientists have built them by fusing small, flat carbon molecules together at their edges. Modifying ...
Tech Xplore / 3D-printable material can heal the body, build better robots and recover critical minerals
A new type of 3D-printable material developed by researchers at The University of Texas at Austin mimics human tissue's ability to sort and filter, allowing certain molecules to pass through while keeping others out. This ...
Medical Xpress / App can help reduce interdialytic weight gain in chronic hemodialysis
For adults receiving chronic outpatient hemodialysis, use of a smartphone-based app designed to support fluid intake restriction is feasible and associated with sustained reductions in interdialytic weight gain (IDWG), according ...
Phys.org / Biosphere reserves: Allies against deforestation in the Western Amazon
Biosphere reserves help curb deforestation in the Western Amazon and, taken together, have prevented the loss of more than 7,400 square kilometers (2,900 square miles) of forest over the last two decades compared with similar ...
Phys.org / Public research and development money can unlock private investment and lasting economic growth
Strategic public investment in research and development (R&D) can begin boosting economic activity immediately, according to a study led by the University of Southampton. The research shows it can also mobilize private R&D, ...
Science X / Different flint, same toolmaking strategy: How Neanderthals adjusted their effort to get the same razor-sharp results
The Neanderthal toolkits found in two Ice Age caves near Le Moustier, in southwestern France, tell a surprising story. Even though the types of rock were very different—large, high-quality flint nodules at Le Moustier and ...
Phys.org / Long-term study finds widespread lithium in drinking water across communities in the western U.S.
Lithium in drinking water is a widespread and persistent source of human exposure across Tribal communities in the Western United States, according to a new study from Columbia University Mailman School of Public Health. ...
