New find in Israel shows that cereal production predates agricultural societies by millennia
Archaeologists have found strong evidence that wheat and barley were refined into cereals 23,000 years ago, suggesting that humans were processing grains long before hunter-gatherer societies developed agriculture. The findings, including the identification of the earliest known oven and hence the oldest evidence of baking, were described in a recent issue of the journal Nature. "This is an observation of key progress in human society, as the beginning of baking was likely a major step forward in nutrition," says author Ehud Weiss, a postdoctoral researcher in Harvard Universitys Department of Anthropology and Peabody Museum. "Our work also provides evidence that ancient people held important knowledge that survives to this day. Ten thousand years before agriculture developed, humans recognized the value of cereals."
Weiss and colleagues from the Smithsonian Institution and University of Haifa found evidence of ancient cereal production at a site called Ohalo II, located in present-day Israel and known from previous research to be 23,000 years old. Situated on the southwestern shore of the Sea of Galilee, this location is covered most years by several meters of water, ensuring an exceptional level of preservation for artifacts entombed within its sediments.

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...
