Ancient bone arrow points reveal organized craft production in prehistoric Argentina
28 December 2025 @ 7:00 pm
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, Sebastián Pastor and Gisela Sario, have published a technological analysis of the manufacturing technique used to create one of the most numerous bone tool types, bone arrow points.
New framework helps climate modelers integrate Indigenous community input into simulations

What if the pages of an old book could tell us who touched them, what medicines they made, and even how their bodies responded to treatment?
ALMA datasets elucidate nearby galaxy NGC 1266's massive molecular outflow
28 December 2025 @ 5:20 pm
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 Dec. 11 on the arXiv pre-print server, could help us better understand the nature of this galaxy.
Glacier loss to accelerate, with up to 4,000 disappearing each year by 2050s
28 December 2025 @ 5:00 pm
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.
Ultra-hot lava world has thick atmosphere, upending expectations
28 December 2025 @ 1:50 pm
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 an alien atmosphere in an unexpected place—an ancient, ultra-hot super-Earth that likely hosts a magma ocean.
Ancient mega-shark ruled Australian seas 15 million years before megalodon
28 December 2025 @ 12:50 pm
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.
Iraqis cover soil with clay to curb sandstorms
28 December 2025 @ 11:01 am
Deep in Iraq's southern desert, bulldozers and earthmovers spread layers of moist clay over sand dunes as part of a broader effort to fight increasingly frequent sandstorms.
Humans made fire 350,000 years earlier than believed, archaeological study finds
27 December 2025 @ 6:00 pm
A team of researchers led by the British Museum has unearthed the oldest known evidence of fire-making, dating back more than 400,000 years, in a field in Suffolk. The discovery shows humans were making fire about 350,000 years earlier than previously known.
Why we may be misreading our dogs' emotions
27 December 2025 @ 3:30 pm
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.
