As anyone who has recently tried out an augmented reality headset knows, the technology is not yet ready to be part of our everyday lives. Researchers have been working to perfect high-performing augmented reality (AR) glasses, but there are a number of challenges. One major problem with...

The past may be a fixed and immutable point, but with the help of machine learning, the future can at times be more easily divined....

Crystals have enthralled humans for thousands of years with their visual beauty and elegant symmetrical shapes, and, more recently, with their numerous technological applications. Fundamentally, these materials are based on a highly regular arrangement of their smallest constituent elements, and the...

In fusion power generation, it is essential that the high-energy particles generated by a fusion reaction in hot plasma heat it to sustain further fusion reactions. The key to this self-heating of the plasma is whether it can be heated by waves created by the high-energy particles....

A team of physicists has created a new way to self-assemble particles—an advance that offers new promise for building complex and innovative materials at the microscopic level....

Scientists from Japan have employed theoretical calculations to model the optical radiation force distribution induced by an arbitral light pattern including an interference pattern. Based on the simulations, they were able to fabricate nano-sized structures in array that may lead to new optical...

Physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have proposed the source of the sudden and puzzling collapse of heat that precedes disruptions that can damage doughnut-shaped tokamak fusion facilities. Coping with the source could overcome one of the...

Researchers have developed a metasurface device that can display three types of images depending on the illumination light. The three-channel device could be used as an anticounterfeiting measure or offer a new way to securely deliver encrypted information....

Due to their very high efficiency in transporting electric charges from light, perovskites are known as the next generation material for solar panels and LED displays. A team led by Dr. Lei Su at Queen Mary University of London now have invented a brand-new application of perovskites as optical...

The riskiest instrument is the voice, at least when it comes to spreading viruses such as SARS-CoV2. Compared to breathing quietly, during singing or speaking infected people release more than 500 times particles into the air, which can contain viruses....
