Every now and again, our planet ponies up a fossil so spectacular that almost all you can do is gape in wonder. The research has been published in Nature.

Indigenous peoples in South America – primarily in Peru, Brazil and other parts of what is considered the Upper Amazon – have been using ayahuasca for medicinal and religious purposes since at least 900 B.C.E. Hieroglyphic paintings depict the use of the sacred brew in a ceremony from the period of 900-250 B.C.E. Western interest in ayahuasca, however, has created some challenges for local Indigenous communities.

Until now, scientists broadly accepted animals first emerged on Earth 635 million years ago. But a team, led by Cardiff University, has discovered evidence of a much earlier ecosystem in the Franceville Basin near Gabon on the Atlantic coast of Central Africa over 1.5 billion years earlier. Their study is presented in Precambrian Research.

Chugging quietly away in the dark depths of Earth’s ocean floors, a spontaneous chemical reaction is unobtrusively creating oxygen, all without the involvement of life. This unexpected discovery upends the long-standing consensus that it takes photosynthesizing organisms to produce the oxygen we need to breathe. This research was published in Nature Geoscience.

Indigenous leaders denounce a “spiritual extractivism” of the psychedelic plant taking place and warn about the impacts of its exploitation on the forest and traditional knowledge.

This year, the famous festival Hayes Pavilion showcased seaweed bioplastic, proving biomaterials can create functional, sustainable structures for events and inspire eco-conscious design.

A chance encounter in remote Australia, and years of painstaking analysis has pushed back evidence for the start of complex life on the planet by 750 million years.

Scientists have found a surprising connection between dinosaurs and ancient grapes. Fossilised seeds found in Central and South America hint that the mass extinction at the end of the “Age of Dinosaurs” might have created the conditions for ancient grapes to spread. See the study published in the journal Nature Plants.

In a paper published in the journal Mycologia this week, researchers from Stellenbosch University (SU) and citizen mycologists describe the two new species as Psilocybe ingeli and Psilocybe maluti.

A giant 280m-year-old salamander-like creature that was an apex predator before the age of the dinosaurs has been discovered by fossil hunters in Namibia.

The discovery offers a glimpse into the Earth’s history and hints at how extreme climate change could alter the planet, according to their findings, published June 5 in the journal Science Advances.

Details of an ancient cousin of modern-day mammals are being revealed for the first time. Hi-tech scanning of an ancient fossil, which was captured in sandstone around 252–254 million years ago, is giving experts valuable insight into the animal’s anatomy and evolution. The study, published in the Zoological Journal of the Linnean Society.

An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere—a nothosaur vertebra found on New Zealand’s South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa.

This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity indicates the halfway point of solar maximum, the height of solar activity, and the beginning of the shift toward solar minimum.

A mysterious Bronze Age wooden circle known as “Seahenge” on England’s east coast was built more than 4,000 years ago in an effort to bring back warmer weather during an extreme cold spell, a new study suggests.

Mysterious dark matter could slosh over our planet like a wave. If it does, it may produce telltale radio waves in Earth’s atmosphere, new theoretical research suggests.
