Animals with ultraviolet color patterns can be found all over nature. Here’s what we know about what purpose these patterns serve. Scorpions are one of many animals that appear to glow under ...

Physicists at CU 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 researchers say the device could ...
