Robots can do in days what humans take years to accomplish at archaeological sites
After lying hidden for centuries off the coast of Greece, a sunken 4th century B.C. merchant ship and its cargo have been surveyed by an international team using a robotic underwater vehicle. The team accomplished in two days what it would take divers years to do. The project, the first in a new collaboration between U.S. and Greek researchers, demonstrates the potential of new technology and imaging capabilities to rapidly advance marine archaeology.
Greek scientists and archaeologists discovered the ancient shipwreck in 2004 during a sonar survey. The wooden Greek merchant ship sank off Chios and Oinoussia islands in the eastern Aegean Sea in 60 meters (about 200 feet) of water, too deep for conventional SCUBA diving. The cargo of 400 ceramic jars, called amphoras, filled with wine and olive oil, are the most visible remains of the shipwreck.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
