Human Lasers

laser-cells-537x358This is truly amazing. Researchers at Harvard Medical School have found that they can get human cells to emit light in a tightly focused beam; in other words – a laser beam. They actually found three different methods for doing this. Who new?

What’s the reason this is important? Tagging cells with fluorescent dyes is “a common and relatively easy way for researchers to label cells by getting them to emit light,” according to New Scientist. However, this process produces a range of wavelengths that make it difficult to distinguish between cells that are tagged differently. Laser light has a narrow range of wavelengths, so every cell in the human body could have a unique, identifiable signature. Incredible.
