In the first weeks of the New Year a team of European scientists drilled successfully through 2002 metres of ice at Dome Concordia, high on East Antarctica`s plateau - one of the most hostile places on the planet. A specially created laboratory on the ice enabled scientists to analyse, for the first time, past climate shifts within hours of each 3 m length of core being drilled - rather than waiting months or years for detailed study back in European labs. The team, working on a seven-year Antarctic research programme to discover the history of the Earth`s climate and atmosphere, report that ice from this depth came from snow that fell 170,000 years ago, when the region was 10ºC colder than it is today.
The 22-person team of scientists and drilling experts taking part in the European Project for Ice Coring in Antarctica (EPICA) worked in temperatures of -20ºC. Complex experiments, involving sweeping ice core segments with a range of electrical frequencies, provide a `fingerprint` of the chemical contents of the ice. It is this chemistry that holds the clues to our past climate.
The team will complete this season`s drilling at the end of January. After on-site analysis the cores will be sent to over 30 different European laboratories for more detailed study. The team will return to Antarctica next year to drill to the bottom of the ice to produce a history of climate and atmospheric composition for the last half a million years.

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.

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...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
