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.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
