The Canadian prairies are facing an unprecedented water crisis due to a combination of climate warming, increase in human activity and historic drought, says new research by the University of Albertas Dr. David Schindler, one of the worlds leading environmental scientists.
"The western prairies are worse than other areas of Canada," said Schindler, co-author of a paper published in the journal "Proceedings of National Academy of Sciences," early online edition. "One of the referees on this paper said, wow, this is like looking out the window of a locomotive 10 seconds before the train crashes. It is a very dire situation".
Although most global studies rank Canada among the top five countries in terms of per-capita water supply, those rankings can be deceptive, argue Schindler and Dr. Bill Donahue, who co-authored the paper. Canadas western prairie provinces (WPP), for example, have an area of 2 million kms that lie in the rain shadow of the Rocky Mountains and as a result, are the driest large area of southern Canada.

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...
