Climate change in daily maximum temperature (K) in summer (June-July-August) simulated by RegCM2. The change is the difference between the future scenario decade (2040s) and current decade (1990s). Warming-hole averages in our analyses use the region delineated by the inner frame (35–40_N, 99–92_W). SLU/ISU graphic
In the future, global warming might not be as severe in the central United States as in other parts of the country, according to scientists at Saint Louis University and Iowa State University (ISU).
Using a detailed regional climate model, these researchers estimate summertime daily maximum temperatures will not climb as high in a Midwestern region -- centered on the Missouri/Kansas border -- as anywhere else in the United States. The hole stretches for hundreds of miles and includes Missouri, Iowa, Nebraska and Oklahoma.
The findings are published in the current issue of Geophysical Research Letters. The article’s lead author is Zaitao Pan, Ph.D., an assistant professor of earth and atmospheric sciences at Saint Louis University. The researchers say the findings underscore the need to consider the impact of global warming on a region-by-region basis.

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...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
