Physicists at the University of Colorado Boulder have demonstrated a new kind of vacuum ultraviolet laser that is 100 to 1,000 times more efficient than existing technologies of its kind. The ...

Scientists have turned a long-standing sci‑fi idea into working hardware, using pure light to move data wirelessly through the air instead of relying on radio waves or copper traces. The result is a ...

Ultraviolet light has a long history as a disinfectant and the SARS-CoV-2 virus, which causes COVID-19, is readily rendered harmless by UV light. The question is how best to harness UV light to fight ...

Performance loss from ultraviolet (UV) light has become a concern for new PV cells, though earlier lab tests may have overstated the issue. Paul Gebhardt, photovoltaic module reliability scientist at ...

An invisible band of radiation with wavelengths from 400 to 10 nm, ultraviolet (UV) light starts at the end of visible light and ends at the beginning of X-rays. The primary source of ultraviolet ...

In a pandemic, people grow desperate for cures, so it’s no surprise that the worldwide outbreak of COVID-19 has people searching for anything that might protect them. Where there’s demand, supply ...

Astronomers working with data from the Hobby-Eberly Telescope Dark Energy Experiment, known as HETDEX, say they have produced ...

Ultraviolet perception is incredibly common in animals—just not in humans. Ed Yong dives into the history of how scientists saw the light. The following is an excerpt from An Immense World: How Animal ...

Ultraviolet (UV) light is a type of radiation. It has more energy than radio waves or visible light but less energy than X-rays or gamma rays. You can be exposed to UV light via natural sunlight or ...
