Computer chips: Engineers use disorder to control light on the nanoscale

Posted: 02 Feb 2015 01:07 PM PST

A breakthrough could lead to the more precise transfer of information in computer chips, as well as new types of optical materials for light emission and lasers.

Wrinkle predictions: New mathematical theory may explain patterns in fingerprints, raisins, and microlenses

Posted: 02 Feb 2015 10:26 AM PST

As a grape slowly dries and shrivels, its surface creases, ultimately taking on the wrinkled form of a raisin. Similar patterns can be found on the surfaces of other dried materials, as well as in human fingerprints. While these patterns have long been observed in nature, and more recently in experiments, scientists have not been able to come up with a way to predict how such patterns arise in curved systems, such as microlenses.

A phone so smart, it sniffs out disease

Posted: 02 Feb 2015 09:33 AM PST

Imagine a smartphone that not only finds the nearest five-star restaurant or hails a cab with a quick click, but also diagnoses illness. New technology would enable smartphones to screen their users' breath for life-threatening diseases, developers report.

Finding valuable materials in metallurgical dumps

Posted: 02 Feb 2015 05:07 AM PST

Since metallic raw materials are scarce in Germany, it is reliant on imports. Yet some of these valuable materials are lying around unnoticed in dumps. Researchers are now compiling a Germany-wide registry of these resources, which reveals where these deposits are located and what metals they contain.

Fitness game for the physically impaired

Posted: 02 Feb 2015 05:07 AM PST

Modern IT has the potential to make fitness training more varied for people with physical limitations. But what exactly is required? Researchers put this question to thalidomide victims, and developed new IT-based fitness training technology in close collaboration with them. The method motivates users with elements found in computer games.

Safe production in Industry 4.0

Posted: 02 Feb 2015 05:07 AM PST

Production facilities and components of Industry 4.0 are linked to the Internet, networked with each other, and thus open to attack. Using an IT security laboratory, researchers offer a test environment in order to simulate attacks on this network and to detect any gaps.

Interconnected IT for business models in rural areas

Posted: 02 Feb 2015 05:07 AM PST

More and more people are moving from rural areas to cities, leaving behind crumbling infrastructures that make daily life difficult for those who stay. Some people are bucking this trend. Researchers are now planning to create new business models in rural areas with the help of interconnected IT.

Supercomputing reveals genetic code of cancer

Posted: 02 Feb 2015 05:07 AM PST

Cancer researchers must use one of the world's fastest computers to detect which versions of genes are only found in cancer cells. Every form of cancer, even every tumor, has its own distinct variants, they report.

Mental health monitoring through 'selfie' videos, social media tracking

Posted: 29 Jan 2015 06:44 AM PST

An innovative approach to turn any computer or smartphone with a camera into a personal mental health monitoring device has been created by researchers. The computer program can analyze "selfie" videos recorded by a webcam as the person engages with social media, to extract a number of "clues," such as heart rate, blinking rate, eye pupil radius, and head movement rate.
