The behavior of a massive ice sheet that existed in northern Europe at the end of the last Ice Age has been outlined for the first time, and researchers believe it may provide a sneak preview of how major ice sheets in Greenland and Antarctica will act in the face of global warming.
The study, which will be published Friday in the journal Science by researchers from Oregon State University, shows that ice sheets can react quite differently depending on the climatic conditions at the time global warming occurs – sometimes actually growing larger and sometimes rapidly disappearing, depending on whether increased snow offsets melting effects, or not.
In this analysis of the Scandinavian Ice Sheet that existed as recently as 10,000 years ago, the study showed that it actually grew for a long period while the climate was warming but still very cold, and then rapidly disintegrated once the climate warmed even further.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
