Laser is produced by a living cell
Laser is produced by a living cell

By Jason Palmer
Science and technology reporter, BBC News
  • A single living cell has been coaxed into producing laser light, researchers report in Nature Photonics.

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

    Flooding the resulting cells with weak blue light causes them to emit directed, green laser light.

    The work may have applications in improved microscope imaging and light-based therapies.
“We do not believe any group of men adequate enough or wise enough to operate without scrutiny or without criticism. We know that the only way to avoid error is to detect it, that the only way to detect it is to be free to inquire. We know that in secrecy error undetected will flourish and subvert”.J Robert Oppenheimer.
Amazing! genetic engineering could lead to "Super" Beings with laser beam eyes, "Mr Laserbeam"! for example ;-)
