An international genomics study… has shown that early Asians made humanity’s longest prehistoric migration. The study was published in Science.

The oldest star chart in the world was made in China more than 2,300 years ago, a hotly debated preprint study finds.

A new study of Venus suggests that the deeply inhospitable world may be more like Earth than we thought. The research has been published in Science Advances.

A new study published in Communications Biology sheds light on how the psychedelic compound DMT changes the brain’s dynamic behavior. Researchers found that DMT reduces the amount of energy the brain needs to switch between different activity states.

Researchers led by the University of Glasgow in Scotland have identified a Late Upper Paleolithic site in the far north of the Isle of Skye, marking the most northerly evidence of Ahrensburgian culture in Britain.

Life truly is radiant, according to an experiment conducted by researchers from the University of Calgary and the National Research Council of Canada. This research was published in The Journal of Physical Chemistry Letters.

A set of ancient wooden spears may be younger than scientists thought and wielded by Neanderthals instead of their ancestors. The research was published Friday in the journal Science Advances.

These Homo sapiens—nomadic hunter-gatherers who populated Western Europe between 11,000 and 35,000 years ago—carry with them a leather rucksack containing objects of value: mostly flint cores and flakes that they will use on the journey as hunting tools, or as ornaments. These are pieces of their homeland. See the research here.

A new case report published in Clinical Neurophysiology describes the first known administration of psilocybin—a psychedelic compound found in certain mushrooms—to a woman in a minimally conscious state.

Five millennia ago, wealth inequality—which had stayed roughly constant for thousands of years—exploded. It has stayed constant, albeit much higher, ever since…One factor, Bowles and Bocconi University economic historian Mattia Fochesato write in a paper recently published in the Journal of Economic Literature, was the ox-drawn plow.

Long used in Indigenous Brazilian rituals, the jurema preta plant, which contains a potent psychedelic, is gaining ground as a potential treatment for depression. The findings were published in the scientific journal Nature in April.

Published in Archaeological and Anthropological Sciences, the findings contradict a widely cited fracture model that credited rock core geometry and stiffness with flaking patterns and predicted that hammer strike angle would have minimal effect on flake formation. Results suggest a greater degree of cognitive control by early human tool makers than previously recognized.

A recent study published in the Journal of Affective Disorders has found that chronic opioid use may interfere with the brain’s ability to generate a placebo antidepressant response, but does not seem to reduce the effectiveness of ketamine.

Two thousand years before the Inca empire dominated the Andes, a lesser-known society known as the Chavín Phenomenon shared common art, architecture, and materials throughout modern-day Peru…one of their most powerful tools wasn’t farming. It was access to altered states of consciousness. That’s according to a new study that uncovered the earliest-known direct evidence of the use of psychoactive plants in the Peruvian Andes

“Theories are like toothbrushes,” it’s sometimes said. “Everybody has their own and nobody wants to use anybody else’s.”

Three scientists in the United Kingdom have modeled the impacts of an icy cometary collision with an Earth-like, tidally locked terrestrial planet…They found even relatively small cometary impacts can significantly disrupt the climate of a terrestrial (Earth-like) tidally locked planet, as well as deliver oxygen to the atmosphere and be a source of an exoplanet’s oceans. Their first of two papers on the topic was published in The Astrophysical Journal.
