First hominins on the Tibetan Plateau were Denisovans: Denisovan mandible likely represents the earliest hominin fossil on the Tibetan Plateau
www.sciencedaily.com
So far Denisovans were only known from a small collection of fossil fragments from Denisova Cave in Siberia. A research team now describes a 160,000-year-old hominin mandible from Xiahe in China. Using ancient protein analysis the researchers found that the mandible's owner belonged to a population that was closely related to the Denisovans from Siberia. This population occupied the Tibetan Plateau in the Middle Pleistocene and was adapted to this low-oxyg

Findings suggest that the abundant metal might have played a key role in early biochemistry before enzymes evolved
Spinning black hole sprays light-speed plasma clouds into space

Astronomers have discovered rapidly swinging jets coming from a black hole almost 8,000 light-years from Earth. The research shows jets from V404 Cygni's black hole behaving in a way never seen before on such short timescales. The jets appear to be rapidly rotating with high-speed clouds of plasma -- potentially just minutes apart -- shooting out of the black hole in different directions.
