In a paper, “The Stonehenge Altar Stone was probably not sourced from the Old Red Sandstone of the Anglo-Welsh Basin: Time to broaden our geographic and stratigraphic horizons?,” published in the Journal of Archaeological Science, the research team details how newly acquired information is overturning a hundred-year-old theory.

Life-size carvings of camels have been found in the Saudi Arabian desert, but archaeologists aren’t sure who created them and when….Radiocarbon dating of two trenches and two hearths nearby indicate that the Sahout site was repeatedly occupied between the Pleistocene (2.6 million to 11,700 years ago) and the Middle Holocene (7,000 to 5,000 years ago), according to the study.

Civil war has broken out in the field of consciousness research.

More research is showing that we carry genes from other kinds of ancient humans, and their DNA affects our lives today.

A recent study, published in the Journal of Psychoactive Drugs, delves into the mysterious world of DMT (dimethyltryptamine) experiences reported on Reddit. Researchers sought to understand the profound sense of familiarity that some users encounter during DMT-induced experiences and the potential implications of this enigmatic phenomenon.

Archaeologists in Kazakhstan have discovered a 3,800-year-old hexagon-shaped structure that they describe as a “pyramid.” The maze-like structure is not as tall as Egypt’s monuments, but currently stands about 10 feet (3 meters) high and likely served as an elite burial site.

In recent years, researchers have gained the power to pull DNA from ancient hominins, including our early ancestors and other relatives who walked on two legs. Ancient DNA technology has revolutionized the way we study human history and has quickly taken off, with a constant stream of studies exploring the genes of long-ago people.

The vast subterranean ocean of Europa, one of Jupiter’s many moons, contains carbon, one of the crucial ingredients for life, scientists have discovered.

A study led by researchers at MIT, the University of Florida, and in Brazil aims to settle the debate over dark earth’s origins. The team has pieced together results from soil analyses, ethnographic observations, and interviews with modern Indigenous communities, to show that dark earth was intentionally produced by ancient Amazonians as a way to improve the soil and sustain large and complex societies.

A pair of interlocking logs that haven’t seen sunlight in half a million years could challenge some fundamental assumptions about the technology and culture of our Stone Age ancestors. See the study here.

“From coca to kava, we should be able to access all plant allies—and understand their beneficial properties.”

A recent meta-analysis suggests that subanesthetic doses of ketamine can offer rapid and sustained anxiety relief, becoming noticeable within a few hours and lasting up to two weeks. The study has been published in the Journal of Psychopharmacology.
