In 1976, Alexander “Sasha” Shulgin was on a roll. The “godfather of psychedelics” had left the Dow Chemical Company, where, after developing the first biodegradable pesticide, he’d been given the freedom to research psychedelic compounds.

New images have been made of one of Scotland’s most significant prehistoric burial sites. Carn Glas, near Inverness, is thought to date to the Neolithic period and be about 5,000 years old.

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 new study suggests that Spain’s ancient peoples shared complex beliefs about death and the afterlife. The research has been published in PLOS One

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.

The relationship between size and number also shows up in everything from ecosystems to language…After collecting data on all of the major types of cells in the body, researchers have revealed a familiar mathematical pattern in these cells’ relationship. There is an inverse relationship between cell size and number, meaning smaller cells are more numerous than larger cells.

Could the lives of the eight billion people currently on Earth have depended on the resilience of just 1,280 human ancestors who very nearly went extinct 900,000 years ago?

Dinosaurs have a reputation for being the most terrifying prehistoric predators, but a newly discovered skull sheds light on a fearsome beast that dominated 40 million years before the first ‘terrible lizards’ walked the Earth. See the research here.
