Listening to music could reduce the dizziness, nausea and headaches virtual reality users might experience after using digital devices, research suggests. Cybersickness -- a type of motion sickness from virtual reality experiences such as computer games -- significantly reduces when joyful music is part of the immersive experience, the study found. The intensity of the nausea-related symptoms of cybersickness was also found to substantially decrease with both joyful and calming music.

Researchers have created a photonic device that provides programmable on-chip information processing without lithography, offering the speed of photonics augmented by superior accuracy and flexibility for AI applications. Achieving unparalleled control of light, this device consists of spatially distributed optical gain and loss. Lasers cast light directly on a semiconductor wafer, without the need for defined lithographic pathways.

A new AI-based system called a semantic decoder can translate a person's brain activity -- while listening to a story or silently imagining telling a story -- into a continuous stream of text. Unlike other thought decoding systems in development, this system does not require subjects to have surgical implants, making the process noninvasive.

Scientists carried out an analysis of hundreds of popular song recordings from 1946 to 2020 to determine the lead vocal to accompaniment ratio, or LAR. The study considered the four highest-ranked songs from the Billboard Hot 100 chart for each year and the results show that, contrary to expectations, the LAR for popular music decreased over the decades in question. This means that, relative to their bands, lead singers are getting quieter.

Why does it feel so difficult to shout upwind? The sensation is common enough to have found its way into an idiom about not being understood. Researchers wanted a scientific explanation for the phenomenon -- and there wasn't been one. They have now shown that our common sense understanding of this situation is wrong. It isn't harder to shout into the wind; it's just harder to hear yourself.

An AI strategy proven adept at board games like Chess and Go, reinforcement learning, has now been adapted for a powerful protein design program. The results show that reinforcement learning can do more than master board games. When trained to solve long-standing puzzles in protein science, the software excelled at creating useful molecules. In one experiment, proteins made with the new approach were found to be more effective at generating useful antibodies in mice than were previous methods. If this method is applied to the right research problems, it likely could accelerate progress in a variety of scientific fields.

Mechanically responsive molecular crystals are extremely useful in soft robotics, which requires a versatile actuation technology. Crystals driven by the photothermal effect are particularly promising for achieving high-speed actuation. However, the response (bending) observed in these crystals is usually small. Now, scientists address this issue by inducing large resonated natural vibrations in anisole crystals with UV light illumination at the natural vibration frequency of the crystal.
