Satellite images have revealed the collapse of Larsen B ice shelf on the Antarctic Peninsula fulfilling predictions made by British Antarctic Survey (BAS) scientists. The collapse of the 3250 km2 ice shelf is the latest drama in a region of Antarctica that has experienced unprecedented warming over the last 50 years.
Earlier this month Ted Scambos of the University of Colorado alerted BAS glaciologists David Vaughan and Chris Doake to images from the NASA MODIS satellite. Meanwhile, in Antarctica Argentinian glaciologist Pedro Skvarca, realised something was happening to the ice shelf and mobilised an aircraft to obtain aerial images confirming the satellite data. While the collapse was still occurring the BAS research ship RRS James Clark Ross navigated her way through the armada of icebergs to obtain photographs and samples.
Over the last month the 200-m thick ice shelf collapsed into small icebergs and fragments. Pooling these new observations scientists will determine when such an event last happened and which ice shelves are threatened in 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...
The oceans are the largest global heat reservoir. As a result of man-made global warming, the temperature in the global climate system increases; around 90% of...
Scientists at Helmholtz Zentrum München have discovered a mechanism that amplifies the autoimmune reaction in an early stage of pancreatic islet autoimmunity prior to the progression to clinical type 1 diabetes. If the researchers blocked the corresponding molecules, the immune system was significantly less active. The study was conducted under the auspices of the German Center for Diabetes Research (DZD) and was published in the journal ‘Science Translational Medicine’.
Type 1 diabetes is the most common metabolic disease in childhood and adolescence. In this disease, the body's own immune system attacks and destroys the...
