This image of Tassiusaq Fjord on the west coast of Greenland shows a moraine -- a pile of boulders and other debris pushed up by a glacier which has long since retreated inland. Scientists at Ohio State University and their colleagues will use plant material found in moraines to gauge the flow and retreat of glaciers on the island. A new study using data from NASA’s Landsat 7 and Terra satellites has shown that the nearby Jakobshavn Glacier is flowing faster than before, and it is retreating rapidly from the Greenland coastline. Data for this image came from Terra’s Advanced Spaceborne Thermal Emission and Reflection Radiometer instrument. Image created by Catherine Tremper, courtesy of Ohio State University.
One of the world’s fastest-moving glaciers is speeding up and retreating rapidly, a recent study has revealed.
The finding has surprised scientists, because while the margins of the Jakobshavn (pronounced "yah-cub-SAH-ven") Glacier had been slowly retreating from the southwest coast of Greenland since before 1900, this retreat appeared to have stopped by the early 1990s when the first accurate measurements were made. Now the glacier is accelerating.
The glacier, one of the major drainage outlets of Greenland’s interior ice sheet, is thinning more than four times faster than it had for most of the 20th Century. Accompanying this thinning is a substantial increase in ice speed.

Flexible, organic and printed electronics conquer everyday life. The forecasts for growth promise increasing markets and opportunities for the industry. In Europe, top institutions and companies are engaged in research and further development of these technologies for tomorrow's markets and applications. However, access by SMEs is difficult. The European project SmartEEs - Smart Emerging Electronics Servicing works on the establishment of a European innovation network, which supports both the access to competences as well as the support of the enterprises with the assumption of innovations and the progress up to the commercialization.
It surrounds us and almost unconsciously accompanies us through everyday life - printed electronics. It starts with smart labels or RFID tags in clothing, we...
The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one sixth, which can significantly improve the energy efficiency of lighting systems.
Light emitting diodes or LEDs are only able to produce light of a certain colour. However, white light can be created using different colour mixing processes.
Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.
Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.
Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
