Fluorescing Fish

January 14, 2014

New findings reported in the NY Times show that when exposed to blue light, fish fluoresce in several vivid colors. This fluorescence was a surprise to the observers, and seemingly also to the NY Times reporter.

 

However, the result is not at all surprising. We found that structured water (EZ water) fluoresces at visible wavelengths. For anyone interested, the paper is:  Chai BH, Zheng JM, Zhao Q, Pollack GH. Spectroscopic studies of solutes in aqueous solution. J Phys Chem A 112(11):2242-2247 (Mar 2008). Since live fish have gel coats (that's why they slip through your hand), and gels contain EZ water, fluorescence is hardly surprising.
