Lasers operate inside single cells

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. Physicist Eric Mazur of Harvard University and his colleagues have severed parts of cells' internal protein skeleton, have destroyed a single mitochondrion, the cell's powerhouse, leaving its hundreds of neighbours untouched, and have cut a nerve cell's connection without killing it. They christen their technique laser nanosurgery.
