A new study demonstrates that certain incised stone artifacts from the Levantine Middle Paleolithic, specifically from Manot, Qafzeh, and Quneitra caves, were deliberately engraved with geometric patterns, indicating advanced cognitive and symbolic behavior among early humans.

A 2,000-year-old Herculaneum scroll buried by the eruption of Mount Vesuvius is filled with lost words that scholars can now decipher thanks to AI and a particle accelerator.

Advanced artificial intelligence is to revolutionise fundamental physics and could open a window on to the fate of the universe, according to Cern’s next director general.

A study on rats found that administering 2,5-dimethoxy-4-iodoamphetamine before giving them an opportunity to take heroin reduced their motivation to do so…The study also identified a specific type of receptor on neural cells that is crucial for this effect. The paper was published in Neuropharmacology.

Piecing together fragments of the world’s earliest known rune stone shows they fit together like a jigsaw puzzle and may have been separated intentionally, shedding light on the varied pragmatic and ritual aspects of early Germanic rune stones. See the research here.

Strange, flat patches on the teeth of ancient Europeans have puzzled archaeologists for centuries. But one researcher thinks he’s solved the mystery: Ice age people as young as 10 years old rocked cheek piercings. The study was published Jan. 23 in the Journal of Paleolithic Archaeology.

The idea of lightsails is something out of science fiction. As early as the 1950s and ‘60s, science fiction writers John Campbell, Arthur C. Clarke and others were toying with the idea of “solar sails” for spacecraft propulsion…Project researchers report in a paper published in Nature Photonics that they have developed a platform to test the materials that could one day form lightsails.

Sheep have been intertwined with human livelihoods for over 11,000 years. As well as meat, their domestication led to humans being nourished by their protein-rich milk and clothed by warm, water-resistant fabrics made from their wool. The findings are published in the journal Science.

The focus of the prospecting campaign was on an area that during the Pleistocene housed a large lake, now completely dried up, with ancient wadis or dry riverbeds crossing the landscape. Egberts collected over 850 artifacts, ranging from very old hand axes from the Early or Old Paleolithic to Levallois reduction flakes from the Middle Paleolithic, all surface material.

Researchers are investigating who — or what — cut ancient tunnels in sandstone in Brazil and nearby nations.

I’m a historian of fire, and my reply is that we have both a narrative and an analog. The narrative is the unbroken saga of humanity and fire, a companionship that extends through all our existence as a species. The analog is that humanity’s fire practices have become so vast, especially in recent centuries, that we are creating the fire equivalent of an ice age.

As described in a study published in the Astrophysical Journal Letters, researchers have collected further evidence of 2024 PT5 being of local origin: It appears to be composed of rock broken off from the moon’s surface and ejected into space after a large impact.

When modern humans journeyed out of Africa, a rapid evolution in their red blood cells may have helped them survive — but it may have also led to the eventual disappearance of Neanderthals, a new study finds.

Our research has revealed that the femur’s contents are arguably the oldest multi-component arrow poison in the world. It’s a complex recipe combining at least two toxic plant ingredients. There’s also evidence of a third toxin.

The bones are at least 1.95 million years old but could be up to 2.2 million years old. They may help build a picture of when early human ancestors left Africa and reached Europe and Asia, and the route they took. This has been an area of debate for decades. The paper was published in Nature Communications.

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.
