Arantxa Aranburu, doctor of the University of the Basque Country and lecturer of the Department of Geology, has proved that the bones of Homo heidelbergensis found in Sima de los Huesos, Atapuerca, are even older than thought.
In the gallery of Sima de los Huesos, Atapuerca, a speleothem was found during a stonecutting, over the bones of the ancestors of the Neanderthals, the Homo heidelbergensis. Speleohtem is a carbonate precipitate, that is, it is made of the same material as stalactites and stalagmites. However, in this case, instead of being column-shape, it is a layer-shape speleothem, and it has very few sediments. Some parts of the speleothem were extracted and they were sent to a dating specialised team.
The geochronologists tested the pureness of the sample and they dated it using the disintegration of uranium/thorium. The dating has demonstrated that the speleothem is older than it was actually thought, and therefore, the bones of Homo heidelbergensis that lay under the speleothem are also older.

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...
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...
