Living lasers

Lasers made from living cells are a reality. Just a matter of time, then, before we're shooting laser beams from our eyes and fingertips.
Has anyone asked Cyclops how he feels about this?

Great - laser cells. Looking forward to some heavily armed bacteria too - e-coli that can shoot death rays, for example.
Nice one, poindexters. You science people are always hatin' on Jesus and his intelligent designs, but when YOU start playing God, you just hand a fucking gonococcus a laser beam and wait for the applause.
Maybe if you were in CHURCH more you'd spend less time fucking up the world with your bullshit evil science inventions - like Frankenstein's monster, nuclear bombs, Windows 7, etc etc.

e. Coli doesn't need death rays. It does that well enough on its own.
I'd actually rather be shot with a laser beam.

Seriously, though, this is pretty cool, though I don't believe them about the medical applications. Sounds like this experiment mostly went from in vitro to in vivo - it was already known that GFP worked for lasing.
My favorite part of the article, however, is the physicist admitting that oops, mol bio isn't as easy as you'd think.

The cell survives the process, although Gather says he killed many cells by mistake while he was still learning the biological techniques to make GFP containing cells. Being a physicist he had to learn a lot of new techniques to insert the GFP gene into HEK cells and then grow them up. 'We both knew in theory how the protein should work, but neither of us had a good idea how to do the hands on work,' says Gather. 'It was quite an experience.'I'm glad it wasn't my tissue culture hood that had physicists messing around in it. I wonder how long the work took them and how much of that time was in the cloning. Was the actual laser work trivial? Was it known how hard you could hit the cells and have them survive the process? I suppose I shall have to read the actual paper to find out. Err...assuming there is one, no link in the article. Hm.

I hate to say this, but once cats have lasers they won't let themselves be used by anyone.

I don't know about you guys, but apart from helping with the digestion of my food, supplying me with a number of vitamins I don't synthesize all that well myself and displacing pathogens, my E. coli are currently whispering that they demand a blood sacrifice!

no more sharks, then?
Oh, we'll still use sharks. Out of nostalgia.
But the lasers will be in their heads, not attached.

As long as you have a 5ns blue light pulsed source embedded in your eye/fingertip directly behind a one-cell thickness ( perfectly aligned! ) array of GFP producing cells, with lasing-transparent material over them....... but yeah, sure!
This is a "living laser" the way the breathless headline talks about it the same way a cow is a "bunker busting missile" - if you took said cow, stapled it to a iron disk and shot it from a railgun.

They're made partly from living cells - the living cells provide the gain medium, and I can see that it might not be hard to get the initial pulses added in from living cells, but the optical cavity - the mirrors at either end, aren't biological.
Or pretty much what lalochezia says, on preview.

I'd do without that skill, personally -- for the same reason some comedian I heard once gave for not owning a gun: "Because I'd never stop using it."

The power levels generated are pretty weak so we're not going to see Cyclops from the X-Men any time soon. At best you might be have a bioluminescent body part that might help you manoeuvre more successfully in the dark.

Some crustaceans use mirrors, instead of lenses, in their eyes (see here for example). So I wonder if you could add biological mirrors to this system....

I thought that article was going to be about xFP transfected cells. I was right.
That glimmer of hope that somehow someone had engineered an organelle to do the thing the two mirrors in an actual laser do... gone. Thanks a lot MeFi. *Sniff

If you want to shoot lasers out of your fingertips, the problem isn't just going to be supplying the mirrors. You must also supply the energy to 'pump' the cells, that is, excite them enough that they amplify light. And you have to do that with... another laser. You really might as well just shoot your enemies with that.
Lots of materials will lase if you pump them hard enough. I seem to recall that tea works, although that's hard to google because there's also a kind of gas laser called a T.E.A. laser.

Actually, could we please get to work on figuring out a way to stop lasers from shooting out of our fingers and eyes? Only the matter seems to have become one of increasing urgency for me.
