Smart Camera Tells Tobacco From Marijuana 167

An anonymous reader writes "A new smart camera technology not only takes a picture but also assays chemical composition, allowing photographers to tell whether that hand-rolled cigarette contains tobacco or marijuana. Designed to speed industrial inspection systems — such as detecting whether food is spoiled — the new smart camera includes spectral filters that make images of corn fields appear differently from hemp. Spectral cameras have been available for decades, but this microchip version should be cheap enough for almost any application."

Anti-Matter Created By Laser At Livermore 465

zootropole alerts us to a press release issued today by Lawrence Livermore National Laboratory, announcing the production of 'billions of particles of anti-matter.' "Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma 'jet.' This new ability to create a large number of positrons in a small laboratory opens the door to several fresh avenues of anti-matter research, including an understanding of the physics underlying various astrophysical phenomena such as black holes and gamma ray bursts." The press release doesn't characterize the laser used in this experiment, but it may have been this one.
