Lasers is for healing.

Good news for sports stars with torn tendons. Research carried out by the US Department of Defense (DoD) shows that laser light can help heal such injuries. It could provide an alternative to glues, sutures or staples, which can all cause disfigurement and infection. And it might even be used to repair damaged eyes, its inventors claim.

DoD experts found that rose Bengal sodium, a dye commonly used to stain biological samples, absorbs light with a wavelength of 550 nanometres ...

Huh. I distinctly rememeber reading the US Navy has had some sucess with infra-red, which is of considerably longer wavelength. Still, is good either way, yes?

Oh, and just in case you were in any doubt as to the sanity of Japan ... here:

Confirmation.
