Phys.org / Ancient bone arrow points reveal organized craft production in prehistoric Argentina
For decades, research and understanding of the diverse bone raw material used by the Late Prehispanic Period (~1220 to 330 cal BP) people of the Sierras de Córdoba were scarce. However, Dr. Matías Medina and his colleagues, ...
Phys.org / ALMA datasets elucidate nearby galaxy NGC 1266's massive molecular outflow
By analyzing the archival data from the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has inspected the outflow of a nearby galaxy known as NGC 1266. Results of the new study, presented ...
Phys.org / Glacier loss to accelerate, with up to 4,000 disappearing each year by 2050s
Thousands of glaciers will vanish each year in the coming decades, leaving only a fraction standing by the end of the century unless global warming is curbed, a study showed on Monday.
Phys.org / Ancient mega-shark ruled Australian seas 15 million years before megalodon
In the age of dinosaurs—before whales, great whites or the bus-sized megalodon—a monstrous shark prowled the waters off what's now northern Australia, among the sea monsters of the Cretaceous period.
Phys.org / Ultra-hot lava world has thick atmosphere, upending expectations
A Carnegie-led team of astronomers detected the strongest evidence yet of an atmosphere around a rocky planet beyond our solar system. Their work, published in The Astrophysical Journal Letters, used NASA's JWST to reveal ...
Phys.org / Why we may be misreading our dogs' emotions
Humans and dogs have been living together side by side for thousands of years, so you would think we know everything about our four-legged friends by now. But we may not understand them as well as we think we do.
Phys.org / Evidence of a quantum spin liquid ground state in a kagome material
Quantum spin liquids are exotic states of matter in which spins (i.e., the intrinsic angular momentum of electrons) do not settle into an ordered pattern and continue to fluctuate, even at extremely low temperatures. This ...
Phys.org / Severe drought linked to the decline of the hobbits 61,000 years ago
An international team of scientists, including the University of Wollongong (UOW), has found compelling evidence that a changing climate played a role in the extinction of the early human species Homo floresiensis, also known ...
Phys.org / Astronomers explore the double nucleus of galaxy NGC 4486B
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed an elliptical galaxy known as NGC 4486B. Results of the observational campaign, published Dec. 16 on the arXiv preprint server, ...
Phys.org / Chinchorro mummification may have originated as a form of art therapy, study suggests
In a recent study published in the Cambridge Archaeological Journal, Dr. Bernardo Arriaza argues that the practice of artificial mummification among the Chinchorro people may have evolved as a response to high infant mortality ...
Phys.org / 16,000 fossil footprints in central Bolivia reveal dinosaur behavior
Legend once had it that the huge, three-toed footprints scattered across the central highlands of Bolivia came from supernaturally strong monsters—capable of sinking their claws even into solid stone.
Phys.org / Detecting the hidden magnetism of altermagnets
Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is found in conventional systems. In conventional antiferromagnets, the sublattices are linked by simple ...
