Researchers from the University of Amsterdam have demonstrated that the climate in South Mexico changed following the collapse of the Maya empire. From preserved pollen grains the paleoecologists could deduce that the climate quickly became dryer.
The climate becoming dryer, explains the decrease in the population following the collapse of the Maya empire. The climate researchers have therefore helped to solve an archaeological mystery.
With the help of pollen grains, the paleoecologists from Amsterdam could accurately reconstruct the climate in a certain region. Each plant will only grow under certain conditions. By working out the overlap between the possible growth conditions for each plant in an area, an accurate picture of the local climate can be constructed.
In the area inhabited by the Mayas, Southern Mexico and Northern Guatemala, the researchers found that round about 1000 AD the climate quickly became dryer. This was about 100 years after the collapse of the Maya empire. The researchers suspect that after the collapse of the well-organised empire, the inhabitants destroyed many wildlife and agricultural areas. This led to erosion, as a result of which the evaporation, and thus the rainfall, decreased.

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...
