In face of changes in precipitation variability, climatic extremes
What does Kansas weather and life have in common? In the words of Forrest Gump, both are like a box of chocolates. "Youre never sure what youre going to get." Rain or drought. Drought or rain.
Concerns about future climate changes resulting from human activities often focus on the effects of increases in average air temperatures or changes in average precipitation amounts. But climate models also predict increases in climate extremes such as more frequent large rainfall events or more severe droughts. This aspect of climate change can lead to an increase in climatic variability without accompanying changes in average temperatures or total precipitation amounts, according to a report by a team of researchers at Kansas State University.
The team, headed by Alan Knapp, a university distinguished professor of biology, and John Blair and Phil Fay, professors of biology, has been studying how grasslands respond to increases in the variability of rainfall patterns to better understand how rapidly and to what extent ecosystems might respond to a future with a more extreme climate. Their findings appear in the latest issue of Science.

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...
