World-first artefact dating method shows humans have lived in shadow of Himalayas for more than 5,000 years
A new technique suitable for dating ancient stone tools has revealed the presence of early humans on the Tibetan Plateau
Few parts of the world would seem as inhospitable to humans as the highlands of the Tibetan Plateau, near the Himalayas. Archaeologists have long wondered when, where and how our ancestors began to explore and occupy these landscapes.
But evidence of early human presence on the plateau has been scarce – and dating the few remaining traces has proven an ongoing challenge.
vasopharm GmbH Announces Results of the NOSTRA III Traumatic Brain Injury Phase III Study
- Post-hoc analysis reveals clinically meaningful and statistically significant improvement in eGOS when Ronopterin is infused within 12 hours after trauma
- But over the entire patient population trial did not meet its primary endpoint
- vasopharm will communicate next steps after discussing these results with Competent Authorities
- Further results to be published in a peer-reviewed journal
- Currently there are no approved treatments for patients with moderate and severe traumatic brain injury

A beam of ethereal blue laser light enters a specialized crystal. There it turns red, a sign that each photon has split into a pair with lower energies and a mysterious connection. The particles are now quantum mechanically “entangled,” linked like identical twins who know each other’s thoughts despite living in distant cities. The photons zip through a tangle of fibers, then ever so gently deposit the information they encode into waiting clouds of atoms.
The transmogrifications are “a little bit like magic,” exults Eden Figueroa, a physicist at Stony Brook University. He and colleagues have concocted the setup on a few laboratory benches cluttered with lenses and mirrors. But they have a much bigger canvas in mind.

Oldest human traces from southern Tibetan Plateau in a new light
For the first time, Michael Meyer and Luke Gliganic from the Department of Geology at the University of Innsbruck have used a new optical dating technique to directly constrain the age of prehistoric stone artefacts from an archaeological site southern Tibet. The findings are more than 5,000 years old and thus the oldest evidence of human presence in this part of the Tibetan Plateau.
Stone tools have been made by humans and their ancestors for millions of years. For archaeologists these rocky remnants – lithic artefacts and flakes – are of key importance. Because of their high preservation potential they are among the most common findings in archaeological excavations. Worldwide, numerical dating of these lithic artefacts, especially when they occur as surface findings, remains a major challenge. Usually, stone tools cannot be dated directly, but only when they are embedded in sediment layers together w

For most of last year, the idea that the coronavirus pandemic could have been triggered by a laboratory accident in Wuhan, China, was largely dismissed as a racist conspiracy theory of the alt-right.
The Washington Post in early 2020 accused Senator Tom Cotton of fanning the embers of a conspiracy theory that has been repeatedly debunked by experts. CNN jumped in with How to debunk coronavirus conspiracy theories and misinformation from friends and family. Most other mainstream outlets, from
The New York Times ( fringe theory ) to NPR ( Scientists debunk lab accident theory ), were equally dismissive. (
