Pretty cool... self-calibrating bio-optical systems somehow?

Awesome! Biological optical elements!

Is it sequenced ?

BTW: Are we capable of DIY DNA synthesis in this group ?

I've done so successfully. :)
I recommend epoch life sciences for gene synth, they were great for me and competitively priced.

I just ordered a promoter sequence from Operon, probably should have checked around but they have done primers in the past and are currently doing a small genome for me also so have had success with them.

Meat lasers?

See also last year's iGEM team from U.Cambridge (following up on their E. chromi work in 2009, and E. glowli in 2010):

I think they should have called their team "E. shiny"...

Up to my knowledge, Lasing has not been
observed in biological systems.
I wonder, what species could have an advantage of it ...
I'm thinking, maybe blinding or killing some prey fish
by strong illumination to the eyes or the brain if the fish
is transparent ...
Communication across vast distances ...

Anyways, artifically it could be possible: If the Reflectin
(or whatever protein) self-arranges to a linear, (optically) excitable
medium with long-living excited state, surrounded by a comparably
intense excitation source ... at least a thinkable idea ...

"the self-assembling protein-laser"

Has anyone tried to do excite GFP to stimulated emission yet ?

Cheers, Matthias

There was some talk about this a while ago, see this thread on GFP laser:

and so it begins....

Very cool.

Well, if it is that easy, it must have occured in nature,
assuming it provides some advantange.
Therefore, I guess, it simply doesn't provide
an advantage for an organism to be able of lasing.

Nevertheless, this allows for the genetic engineering of
biological lasers, that are grown, instead of assembled,
with a self-"healing" (self-regenerating) medium.

Cheers, Matthias

[Matthias Bock]

;-) well, maybe not exactly like this ...

oh, and I forgot one laser usage: a photo-sensor barrier
