Glaciers existed in Britain as late as Georgian era

New evidence indicates glaciers present 11,000 years later than believed

Research led by a scientist from the University of Exeter has shown that Britain was home to small glaciers within the last few centuries – around 11,000 years later than previously thought.

Dr Stephan Harrison of Geography has established that small glaciers almost certainly existed in the Cairngorm mountain range in Scotland as recently as the 18th century, contrary to the long held belief that Britain’s last glaciers melted around the 9th millennium BC. (more…)

Researchers Reveal Structure of Carbon’s ‘Hoyle State’

A North Carolina State University researcher has taken a “snapshot” of the way particles combine to form carbon-12, the element that makes all life on Earth possible. And the picture looks like a bent arm.

Carbon-12 can only exist when three alpha particles, or helium-4 nuclei, combine in a very specific way. This combination is known as the Hoyle state. NC State physicist Dean Lee and German colleagues Evgeny Epelbaum, Hermann Krebs and Ulf-G. Meissner had previously confirmed the existence of the Hoyle state using a numerical lattice that allowed the researchers to simulate how the protons and neutrons interact. When the researchers ran their simulations on the lattice, the Hoyle state appeared together with other observed states of carbon-12, proving the theory correct from first principles. (more…)
