System detects tissue changes
Digitally altered Denver suburb
Although these two images of a Denver suburb look virtually identical when compared side by side, some details have been digitally altered for illustration. Although most people can spot the lake and building missing from one photo (middle left), the Change Detection System (CDS) program immediately reveals that a swimming pool (lower right neighborhood) and a dirt track (upper right field) are also absent from one of the images. The large photo below has graphic highlights in yellow to emphasize the changes that CDS software makes visible. (Photo by Space Imaging®, Digital Airborne Imaging System)
Mammograms, X-rays and other pricey medical scans do little good if doctors cant see the tiny changes that signal early stages of disease. But such warning signs are often too subtle to spot by eye, and too complex for computers to interpret. Scientists at the U.S. Department of Energys Idaho National Engineering and Environmental Laboratory have developed the Change Detection System, technology that highlights slight differences between digital images. In fact, lead researcher Greg Lancaster convinced doctors of the programs power when he used it to compare scans of his own brain after hed had a tumor removed. One medical technology firm is already looking to license the program.
This medical advance is a direct result of applying national security technology, which was initiated through funding from the DOEs Applied Technology Program. The CDS software is so quick, easy and affordable that it now boasts a spot among the 100 most technologically significant products introduced in the past year. R&D Magazine editors notified the winners in July and will feature the winning products in the September issue.

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...
