Femtosecond Lasers for Nanosurgery
Roland Piquepaille writes "In "Lasers operate inside single cells," Nature writes that nanosurgery can be achieved by vaporizing some components of living cells without killing the cells themselves. "With pulses of intense laser light a millionth of a billionth of a second long, US researchers are vaporizing tiny structures inside living cells without killing them. The technique could help probe how cells work, and perform super-precise surgery." This was developed by Eric Mazur of Harvard University and his colleagues. This summary contains more details and references about the process and these microexplosions. Please note that it's a very different technique from the one described six months ago in a previous Slashdot reference, Surgery with Femtosecond Lasers."
go sco/lunix!
out of office for bj. please leave a message.
Is that perhaps because cosmetic surgery is performed mostly on females getting a second face lift?
From excellent karma to terible karma with a single +5 funny post...
"You see, I was born with too much smarts, so they had to operate to relieve the pressure.."

I second that. I don't know how he does it, but ArticleText"Troll" (I have to use quotes because he's the farthest thing from a troll that you'll ever find on /.) somehow manages to get to articles before they are slashdotted, on a remarkably consistent basis. Then he posts the article text here so we can all enjoy it. Putting him on your friends list is pretty much the smartest move you could ever make.

First Officer Spock: Thank you Dr. McCoy, that was good work. I am extremely grateful for attaching me back to my body.
Dr. McCoy: Yes, and all thanks to my superprecise femtosecond lasers that emit pulses of intense laser light a millionth of a billionth of a second long.
Voiceover: To get your superprecise femtosecond lasers that emit pulses of intense laser light a millionth of a billionth of a second long, dial 1-800-FEMTO NOW! Now you too can perform superprecise surgery in the comfort of your own starship. Call NOW!
