Gallery: Scientists in Uruguay Genetically Engineer Sheep to Glow Under...


When you can’t sleep and need to count sheep to drift off, try wrapping your brain one of these eerie glowing lambs from South America. Scientists from the Animal Reproduction Institute of Uruguay (IRAUy) have genetically engineered nine animals to light up under UV light by incorporating a gene from the Aequorea victoria jellyfish. The research is intended to help easily identify genetically modified processes in animals.

    Start by identifying the ‘wrongs’ you want us to consider. Don’t just claim it is wrong but elaborate on the matter by constructing a sound argument. How about start from the first level and go from there…

    This is pretty awesome. It shows how far genetic engineering has already gone. The sheep themselves are fine, and bioluminescence like that is indeed a pretty easy way to tell if the engineering works or not.

    Research like this is vital for the long-term survival of humans. You might not like it, but the fact is that we humans have been putting every effort to stop our own evolution in an attempt to save lives (or, in ecological terms, to make sure that our population size doesn’t drop). Which is now coming back to bite us, since there is no longer a mechanism for controlling mutation spread, hence a high number of genetic diseases. Thus there are two choices – either learn to fix the corrupt genetic code, or allow evolution to continue by succumbing to even more genetic diseases. I would rather choose the first option.

    This is just wrong on every level.
