Glowing Chinese Pig Passes Traits to Young
porkpickle writes A cloned pig whose genes were altered to make it glow fluorescent green has passed on the trait to its young, a development that could lead to the future breeding of pigs for human transplant organs, a Chinese university reported."
And let's see how long they last versus night predators.
No! No! No! I wanted "Green eggs" and "ham". Not "Green eggs and ham". Green eggs. Not green ham.
When "glow green" genes are spliced into an organism, that's usually a gene for the expression of "Green Fluorescent Protein," a protein native to Aequorea jellyfish. Green Fluorescent Protein, as the name implies, is "fluorescent," not bioluminescent or phosphorescent. The excitation and subsequent emission of fluorescence occurs on a very fast timescale (as opposed to phosphorescence, where you can "charge" a material with light, then take it to a dark place, where it will emit light gradually). Therefore, you need to shine a light on fluorescence materials to make them glow- shining a light in the blue or near UV (black light) wavelengths on one of these pigs will cause them to absorb that light, and in turn emit light which is green in color.
"FDA staff reviewers expressed concern about the number of patients who were left out of the study because they died."
