No, the above is not an exaggeration. I’m fine with nixing flying hovercars so long as we get this. Discovery writes:
The researchers report that they were able to create bright laser pulses that lasted a few nanoseconds with a single cell. Amazingly the cells were not damaged during the production of the laser light but were able to withstand hundreds of pulses.
The project took place at the Wellman Center for Photomedicine in Massachusetts. The key to this breakthrough involved the use of the widely studied protein known as green fluorescent protein. This protein, which was first discovered in jellyfish, has (as the name implies) the property of generating light.
Although there are no immediate plans to use this technology, the erosion of the barrier between optical technologies and biology could open many doors in therapy and research.
