The melting of an Antarctic ice sheet roughly 14,000 years ago triggered a period of warming in Europe that marked the beginning of the end of the Earth’s last ice age, says a new study.
A paper in the March 14 issue of the journal Science suggests that a catastrophic collapse of an Antarctic ice sheet dumped roughly a million cubic litres per second of freshwater into the southern oceans, changing the climate thousands of kilometres to the north and ushering in a dramatic climate shift known as the Bølling-Allerød warm interval.
"The paper describes the last gasp of the ice age," says Jerry Mitrovica, the J. Tuzo Wilson Professor of Geophysics at the University of Toronto and co-author of the paper. "These are the spasms that got us from a climate where three kilometres of ice covered Canada to today’s conditions. We’re saying that what pulled us out of this - what ended the ice age - was this remarkable sequence of events. It all started in the Antarctic."

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
