	Did they read Einstein's 1905 paper? __________________ In vino veritas; in cervisia carmen; in aqua E. coli.

	I know that this is from Discovery News but the inaccuracies are atrocious. The article actually claims that a Laser (Light Amplification by Stimulated Emission of Radiation" fires electrons at a piece of gold to produce photons. WTF A laser is a coherent light source that produces photons itself not electrons. As for the idea that Breit-Wheeler electron-positron production has yet to be observed in a lab, that is silly.

	The title is wrong --- it's not turning light into matter, which would violate an number of physics conservation laws. It's turning light into matter and antimatter.
