Scientists will soon be extracting the deepest Arctic sedimentary cores ever drilled from the Lomonosov Ridge, in the deep oceans more than 2,000 km off the coast of Norway. They will core to a depth of about 500 metres under the seabed. From studying these cores the researchers expect to answer questions such as what caused the ice-age? So far the deepest oceanic sediment core extracted from the Arctic is only from a depth of 16 metres.
Seafloor sediments conceal a rich history of the Earth. Studies of sedimentary cores indicate that the pace of climate change varies over time. But what actually initiates these changes? How are they spread over time and what circumstances amplify or reduce the climatic effects of events such as earthquakes or volcanic eruptions?
"For the first time scientists will be able to look back at a continuous record of Arctic climate history over the past 50 million years and find answers to some of these questions" says Andy Kingdon, Outreach Director for the Arctic Coring Expedition (ACEX). He adds, "The Lomonosov Ridge is as near to being a pristine, uncontaminated site as you can possibly get so we are really excited about what we might find."

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
