The Raman spectrometer emits a laser beam.
What’s the News: Using a laser, a super-strong telescope, and some physics know-how, researchers say they have impressive power to look through solid barriers. Scientists have developed a technique to do so using Raman scattering, which is the change in energy of photons bouncing off a material. The technique could be used to detect hidden explosives or do geological analysis.
What’s the News: The next generation of bomb detectors may come from an unusual source: bee venom, the stuff that hurts like all get-out when you get stung. A team of researchers at MIT have used fluorescent carbon nanotubes and venom proteins called bombolitins that bind to single molecules of explosives like TNT to create an exquisitely sensitive detector.
