Researchers in the emerging field of spatial computing have developed a prototype augmented reality headset that uses holographic imaging to overlay full-color, 3D moving images on the lenses of what would appear to be an ordinary pair of glasses. Unlike the bulky headsets of present-day augmented reality systems, the new approach delivers a visually satisfying 3D viewing experience in a compact, comfortable, and attractive form factor suitable for all-day wear.
“Our headset appears to the outside world just like an everyday pair of glasses, but what the wearer sees through the lenses is an enriched world overlaid with vibrant, full-color 3D computed imagery,” said Gordon Wetzstein, an associate professor of electrical engineering and an expert in the fast-emerging field of spatial computing.
Wetzstein and a team of engineers introduce their device in a new paper in the journal Nature (“Full-colour 3D holographic augmented-reality displays with metasurface waveguides”).
By nudging a thorium-229 nucleus into a higher energy state, physicists have made it possible to develop a nuclear clock that could probe the most fundamental forces in physics. However, there is still a long way to go.

How can studying an exoplanet’s ozone help astronomers better understand its habitability potential? This is what a recent study published in the Monthly Notices of the Royal Astronomical Society hopes to address as a team of international researchers investigated how an ozone on the nearest exoplanet to Earth, Proxima Centauri b, could influence its own climate over time. This study holds the potential to help astronomers better understand how an exoplanet’s ozone could influence its formation, evolution, and potential habitability, and could have implications on how astronomers study Earth-like exoplanets throughout the cosmos.
“Imagine a world where ozone affects temperature and wind speed and holds the key to a planet’s very habitability,” said Dr. Assaf Hochman, who is a senior lecturer in the Institute of Earth Sciences at the Hebrew University of Jerusalem and a co-author on the study. “Our study unveils this intricate connection and underscores the importance of considering interactive ozone and other photochemical species in our quest to understand Earth-like exoplanets.”
For the study, the researchers used a series of computer simulations to ascertain how an active ozone on Proxima Centauri b could influence the exoplanet’s climate and potential habitability. In the end, the researchers discovered that an ozone layer on Proxima Centauri b could greatly influence the temperature and wind circulation patterns throughout its atmosphere. Additionally, they also found altitude also played a high role in the atmospheric temperature and temperature variances, as well. The researchers emphasized how these findings could help future researchers better understand the potential habitability of an exoplanet, noting how a potential ozone layer on Proxima Centauri b could greatly influence its climate.
