“It’s the ring! The ring she’s wearing is cursed!” Sam shouts his words across the room, knowing Eileen can’t hear him. His legs are tensed, struggling with whatever this curse is that has him paralyzed on the floor, like his feet are stuck in cement. By the grace of some higher power, or more likely by sheer luck, his hands are free, and he waves them wildly until he catches Eileen’s attention.

“It’s her ring!” he says again, pointing to his own finger and then back at the woman.

Separation of a highly fluorescent anthranilic acid derivative from the reaction mixture.

The upper organic layer dissolved almost completely my compound from the reaction mixture and could be separated in one step. A good point was that the compound had a really strong fluorescence and if I placed an UV lamp next to the separation funnel it was easily observed that the water phase contained almost none of the title compound. 

Get the glow: the secret to deep-water corals’ radiance 

Researchers have pinpointed the reason that deep-water corals emit an eerie glow: to help their algae do photosynthesis.

Scientists know that in shallow waters, the organisms light up green, using fluorescent proteins as a kind of sun block. The proteins soak up harmful ultraviolet rays, re-emit green light and shield their symbiotic algae, which supply most of the corals’ energy needs through photosynthesis.

In 2015, a team led by Jörg Wiedenmann at the University of Southampton, UK, found that deep-dwelling corals also fluoresce — this time in an array of vivid yellows, oranges and reds. Some of these organisms live in water as deep as 165 metres, where little sunlight reaches them, and most of what does is in the blue part of the spectrum. So the researchers suspected a different reason for the glow.

Now, Wiedenmann thinks his team has the answer: the corals use a fluorescent protein to make the most of the small amount of light available in their habitats for photosynthesis. In other words, the deep-water corals and their shallow relatives fluoresce for opposite reasons.
