Breakthrough for IT Using Heusler Materials

Breakthrough for IT Using Heusler Materials

It is the breakthrough that physicists and chemists around the world have long anticipated and it will play a pivotal role in information technology in coming years. Researchers at Johannes Gutenberg University Mainz (JGU) have managed, for the first time, to directly observe the 100 percent spin polarization of a Heusler compound. Heusler alloys are [...]

Computer Program to Teach Itself Everything?

Computer Program to Teach Itself Everything?

In today’s digitally driven world, access to information appears limitless. But when you have something specific in mind that you don’t know, like the name of that niche kitchen tool you saw at a friend’s house, it can be surprisingly hard to sift through the volume of information online and know how to search for [...]

Measuring Fine Dust Concentration Via Smartphone

Measuring Fine Dust Concentration Via Smartphone

Big cities in the smog: Photos from Beijing and, more recently, Paris clearly illustrate the extent of fine dust pollution. But what about our direct environment? What is the pollution concentration near our favorite jogging route? Scientists of Karlsruhe Institute of Technology (KIT) are developing a sensor that can be connected easily to smartphones. In [...]

Screening for Autism: There’s an App for That

Screening for Autism: There’s an App for That

Most schools across the United States provide simple vision tests to their students — not to prescribe glasses, but to identify potential problems and recommend a trip to the optometrist. Researchers are now on the cusp of providing the same kind of service for autism.   Researchers at Duke University have developed software that tracks [...]
