A new milestone has been reached in the development of a practical quantum teleportation system — researchers have for the first time succeeded in the teleportation of information between two separate clouds of gas atoms, over long-distances. And not just once, the method is apparently already extremely reliable — working every single time that it’s
How do you measure something when your ruler only goes back 40 years? It’s like trying to measure the height of a tree with your school ruler: you need more ruler! Climate scientist Aslak Grinsted of the Centre for Ice and Climate at the Niels Bohr Institute at the University of Copenhagen wanted to find
Ancient nettle cloth that was found in one of Denmark’s richest known Bronze Age burial mounds, Lusehøj, was actually made far away in Austria, new research has found. This discovery suggests that long-distance trade networks during the Bronze Age, around 800 BC, may have been much more common than previously thought. “2,800 years ago,
A new and extensive study that is the biggest of its kind, involving over 40 academic institutions around the world, has tackled one simple question: did humans or climate change cause the extinction of the megafauna of the Ice Age. Mammals such as the woolly rhinoceros and woolly mammoth are long since gone, but leave
A new doctoral thesis has shown that industrial chemicals are making their way north to the Arctic from the industrialised world via air and sea currents, where they are then absorbed by the sea’s food chains, of which the polar bear is at the top.
Much concern has been made about the dramatic drop in Arctic sea ice levels over the past decade, but new research out of Denmark suggests that the extent of the Arctic sea ice is extremely variable.
According to new research into the collapse of a centuries old colony established by Vikings in Western Greenland, human adaptation to changing climate may not be a new problem at all.
