Spintronics: significant progress
An international research team has achieved a breakthrough in atomically thin antiferromagnetic tunnel junctions. This shows the great potential of antiferromagnetic materials for storage technology. Spintronics (spin electronics) deals with the use of electron spin in electronic devices. In contrast to conventional electronics, which only uses the charge of the electrons, spintronics also uses the spin of the electrons, i.e. a "direction of rotation" at the atomic level, to store and process information.

One-way street for sound waves
One-way street for sound waves
Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Be it water, light or sound: waves usually propagate in the same way forwards as in the backward direction. As a consequence, when we are speaking to someone standing some distance away from us, that person can hear us as well as we can hear them.

Nanostructures enable on-chip lightwave-electronic frequency mixer
Lightwave electronics aim to integrate optical and electronic systems at incredibly high speeds, leveraging the ultrafast oscillations of light fields. Imagine how a phone call works: Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be heard clearly on the other end.

AI-powered antenna revolutionizes bone fracture diagnosis
A University of Waterloo engineer has paired inexpensive wireless communication antennas with artificial intelligence (AI) to improve how doctors can detect bone fractures. Determining bone fractures using traditional diagnostic methods such as x-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI) takes time - such equipment is not readily available in ambulances or primary care facilities and, with health care services in high demand, many people have to wait for an x-ray or scan once they arrive at the hospital.
