For the first time in the controversial saga of the famous Vinland Map, scientists say they have shown with certainty that the supposed relic is actually a 20th-century forgery. The findings are reported in the July 31 print issue of Analytical Chemistry, a peer-reviewed journal of the American Chemical Society, the world’s largest scientific society.
The Vinland Map -- a drawing that suggests Norse explorers charted North America long before Columbus -- has given scientists and historians a fertile platform for debate throughout its contentious history. Several studies have questioned its authenticity, but disagreement about techniques and interpretations has left some adherents to the map’s 15th-century origins unconvinced.
While other evidence has already established the pre-Columbian presence of the Vikings in North America, the map still serves as an important piece of history and has been valued by some at more than $20 million. It resides at the Beinecke Rare Book and Manuscript Library of Yale University.

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...
