LED light bulb from Salmon DNA

Scientist's have made a LED light bulb from Salmon DNA. Check this article.

Calm down scientists. Is making a light bulb from fish DNA really necessary? Or are you just doing it because you can? This is similar to a hummer. Why, oh why, did anyone ever make a crazy inefficient car that normal people can waste their money on. The car companies knew it was excessive, but they know there are people out there compensating for their lack of life skills with an absurd car. The lab people at the University of Connecticut were like.. hey, we made DNA glow. I'm tired of people not understanding our research, LETS MAKE A LIGHT BULB!

Okay, it is kinda cool. You would have a light bulb with salmon DNA on it and it changes the intensity of LED light? Making DNA florescence has been happening for years. Here's how it works:

There is a protein in jelly fish named GFP, green florescent protein. Basically, when certain wavelengths of light hit these proteins (ex UV light) an emission of light is the product of the reaction (i think its something like when a reaction causes heat to be released). These protein sequences were isolated and now it is used in many ways. They developed a way to tag certain genes with this protein (if the gene creates proteins they then have the ability to glow under UV light once tagged). So to see if a gene is involved in a certain activity, they run an experiment under conditions causing an assumed reaction and see if the now glowing protein is made, and can compare intensities with a control. Basically, it's like in a factory if you put red paint on a roller so that the finished product would get hit with paint as it entered a bin.. you would be able to count the products that came from that roller. Not a perfect example, but it will do I hope.

More to the point these crazy people tagged a piece of DNA then spun it until it became fibrous and then wrapped LED lights in it to be able to change the light intensity based on the dye use. It seems like there should be an easier way to do this. Poor salmon didn't want them to make their DNA all glow-y then used to dim lights.

Moral of the story: shit's wak.
