Collaborating scientists at the U.S. Department of Energy’s Ames Laboratory, Brookhaven National Laboratory, and Princeton University have discovered a new layered ferromagnetic semiconductor, a rare type of material that holds great promise for next-generation electronic technologies.

As the name implies, semiconductors are the Goldilocks of electrically conductive materials— not a metal, and not an insulator, but a “just-right” in-between whose conducting properties can be altered and customized in ways that create the basis for the world’s modern electronic capabilities. Especially rare are the ones closer to an insulator than to a metal.

What can fly like a bird and hover like an insect? Hummingbirds. If drones had this combo, they would be able to maneuver better through collapsed buildings and other cluttered spaces to find trapped victims. Purdue University researchers have engineered flying robots that behave like hummingbirds, trained by machine learning algorithms based on various techniques the bird uses naturally every day.

This means that after learning from a simulation, the robot “knows” how to move around on its own like a hummingbird would, such as discerning when to perform an esca...

Scientists have succeeded in developing a piece of hardware which could pave the way for creating computers resembling the human brain. They produced a chip containing a network of artificial neurons that works with light and can imitate neurons and their synapses. This network is able to ‘learn’ information and use this as a basis for computing. The approach could be used later in many different fields for evaluating patterns in large quantities of data.

The researchers were able to demonstrate, that such an optical neurosynaptic network...
