Optoelectronics research could bring holograms to your smartphone and closer to everyday use

New research from the University of St Andrews paves the way for holographic technology, with the potential to transform smart devices, communication, gaming and entertainment.

In a study published in Light: Science & Applications, researchers from the School of Physics and Astronomy created a new optoelectronic device from the combined use of holographic metasurfaces (HMs) and (OLEDs).

Until now, holograms have been created using lasers. However, researchers have found that using OLEDs and HMs gives a simpler and more compact approach that is potentially cheaper and easier to apply, overcoming the main barriers to hologram technology being used more widely.

AI tool targets RNA structures to unravel secrets of the dark genome

We mapped the human genome decades ago, but most of it is still a black box. Now, UNSW scientists have developed a tool to peer inside and what they find could reshape how we think about disease.

Your genome is the genetic map of you, and we understand almost none of it.

Our handle on the bits of the genome that tell the body how to do things (“make eyes blue,” “build ,” “give this person sickle cell anemia”) is OK, but there are vast areas of the genome that don’t appear to do anything.

Antiferromagnets outperform ferromagnets in ultrafast, energy-efficient memory operations

Advances in spintronics have led to the practical use of magnetoresistive random-access memory (MRAM), a non-volatile memory technology that supports energy-efficient semiconductor integrated circuits.

Recently, antiferromagnets— with no net magnetization—have attracted growing attention as promising complements to conventional ferromagnets. While their properties have been extensively studied, clear demonstrations of their technological advantages have remained elusive.

Now, researchers from Tohoku University, the National Institute for Materials Science (NIMS), and the Japan Atomic Energy Agency (JAEA) have provided the first compelling evidence of the unique benefits of antiferromagnets.

“Heavy” Electrons Hold the Key to a New Type of Quantum Computer

Discovery of Planckian time limit offers new opportunities for quantum technologies. A collaborative team of researchers in Japan has identified “heavy fermions”—electrons with greatly increased effective mass—that display quantum entanglement controlled by Planckian time, the fundamental unit of

DNA From a Mysterious Extinct Hominin May Have Helped Ancient Americans Survive

A newly discovered Denisovan gene, hidden within human DNA, may have helped the first Americans adapt to their new world. Thousands of years ago, early humans braved a dangerous migration, traveling across vast stretches of ice over the Bering Strait to reach the unfamiliar lands of the Americas.
