Sea ice strongly linked to climate change in past 90 000 years

"The Arctic sea ice responded very rapidly to past climate changes. During the coldest periods of the past 90,000 years the sea ice edge spread relatively quickly to the Greenland-Scotland Ridge, and probably far into the Atlantic Ocean." says first author Ulrike Hoff, a researcher at Centre for Arctic Gas Hydrate, Environment and Climate (CAGE).

Richard III Society grant for medieval masculinity PhD research

If you found yourself up against Henry VIII at a jousting tournament, it might have been advisable to let the king win. It proved to be a good career move for Charles Brandon. He was a fantastic jouster, able to beat all his opponents…except Henry. However, he did end up as a Duke and married the king’s sister.

Roman-Britons had less gum disease than modern Britons

The Roman-British population from c.200-400 AD seems to have had much less gum disease the what we experience today, according to a new study of skulls at the Natural History Museum led by a King’s College London periodontist. The startling findings provide further evidence that modern habits such as smoking can be detrimental to oral health.

Genomic data support early contact between Easter Island and Americas

It is possible people may have been making the trip from Easter Island to the Americas a long time before the Dutch commander Jakob Roggeveen arrived with his ships in 1722, according to new genomic evidence demonstrating that the Rapanui people living on that most isolated of islands had significant contact with Native American populations hundreds of years earlier. The findings reported that the Cell Press journal Current Biology yesterday provide the first genetic evidence for such an early trans-Pacific route between Polynesia and the Americas, an impressive trek of over 4,000 kilometers (nearly 2,500 miles).

Ancient Europeans intolerant to lactose for 5,000 years after they adopted agriculture

Through the analysis of DNA extracted from the petrous bones of skulls of ancient Europeans, scientists have identified that these peoples remained intolerant to lactose (natural sugar in the milk of mammals) for 5,000 years after they implemented agricultural practices and 4,000 years after the onset of cheese-making among Central European Neolithic farmers.
