Ray-finned fishes evolved bioluminescence at least 27 chemistry and others by housing luminous bacteria, a repeated evolutionary experiment spread across deep-sea, inshore and reef lineages using different molecular machinery to make visible light Saving Tips July 22, 2026 Ray-finned fishes have evolved bioluminescence independently at least 27 times. Some lineages manufacture light inside their own tissues, while others…
The colour magenta does not exist anywhere in the spectrum of visible light, and your brain manufactures it on the spot whenever red and blue cones fire together, inventing a hue to fill a gap that physics never bothered to provide. Saving Tips June 6, 2026 Stare at a rainbow and try to find magenta. It will not be there. The visible spectrum runs from roughly…
