El Niños effects on a Pacific Northwest river valley offer forecasters a window to dry years ahead
PARCHED--Water officials keep tabs on snowpack and reservoir levels to help them forecast drought, this for the Yakima River Valley, mid-February 2005. If this snowpack picture holds up, reservoirs will be depleted and farmers in many water districts can expect irrigation sources to run dry this summer. As climate in the region changes, this forecast will become more and more common, with severe consequences for those who do not plan.

Global warming conversations have shifted from whether climate is changing to how we will deal with the inevitable consequences. And the price you pay will depend on where you live and how well you prepare, suggests one of the most detailed studies to date on global warming and its likely effect on human activity.
"Like politics, global climate change is local," said Michael J. Scott, a staff scientist at the Department of Energys Pacific Northwest National Laboratory in Richland, Wash. "Our behavior where we live must change with the climate if we are to stave off economic and natural catastrophemeet the challenge Mother Nature may hand us in the next few years."

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...
