Laser is produced by a living cell

A new method of creating laser light from a single cell may help improve light-based therapies.
A cell able to produce a light-emitting protein from a species of glowing jellyfish is first engineered, then flooded with blue light causing the resulting cells to emit a directed beam of green laser light.
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.

Its too bad more animals didn't have bioluminescence, what a magic world this would be.

This paves the way for bioluminescent tatoos. Can you imagine? Everyone wandering around glowing in colors. Wow!

@ Taut: We'll have to look at the Japanese for that kind of invention, lol.

The article says the bio laser can heal itself. What if they started developing building material out of cells? they could just create bigger and stronger cells and grow them to fit the given dimensions. Imagine buildings that can heal themselves
