The technique starts by engineering a cell that can produce a light-emitting protein that was first obtained from glowing jellyfish."

    The laser/shark meme is really boring and pathetic. Can't people move on?

    Just google "Single-cell biological lasers" and you get some free sources for the article. Looks like they "shined" blue light on a cell which was positioned between 2 mirrors. So out of the 3 parts needed for a laser, 2 of them were not biological. I say good news that they grew cells capable of lasing the light but the article headline really jumps to conclusions and dramatizes it a bit, what am I saying? Nature.com [nature.com] had the article.

    From what I can gather of TFA, the cell isn't really a laser per se, as much as it is a cell that, genetically engineered to express GFP, can survive and be observed while be used as part of the lasing medium in a GFP-based organic dye laser(which is stimulated by blue light from outside the tube in which the cell(s) and the GFP dye fluid are placed).

    That is pretty cool, and I suspect that there will be some very elegant live-cell imaging that comes out of applications of this technique; but it leaves me wondering how small a complete biological laser could be: ie. something that both expresses the proteins needed to make up the lasing medium and uses some flavor of bioluminescence to pump its own lasing medium...
