Opal is generally known for its fluorescence when put under UV light, but Mexican hyalite opal is unique in that it can also fluoresce in natural light.

Birds-of-paradise are known for their extravagant courtship displays, featuring elaborate dances and vividly colored plumage.

He then shone the UV light on wombats and marsupial moles — and they also lit up, the outlet said. Dr. Paula Anich, the US researcher from Northland College who made the platypus discovery, said ...

It fluoresces bright green under black light due to the trace amounts of uranium contained within the opal layer.” The more uranium a hyalite deposit contains, the brighter it glows.

But under UV light they appeared green or cyan. The fur of the platypus absorbs UV (wavelengths of 200-400 nanometers) and re-emits visible light (of 500-600 nanometers), making it fluoresce.

Their verdant fluorescence begins to appear under normal daylight, and at night under a UV torch, the bright green glow of the nests can be seen up to 65 feet (20 meters) away, the authors wrote ...

The springhare — whose coat glows a patchy pinkish-orange under UV light — joins the platypus and other mammals with this perplexing trait. The springhare is yet another addition to the ...

New research finds that springhares, hopping rodents native to southern Africa, glow under UV light. J. Martin and E. Olson, Northland College; from Olson et al. 2021, Scientific Reports ...
