Scientists at Ludwig-Maximilians-Universit=E4t in Munich and the Max Planck Institute of Quantum Optics in Garching have opened up a new chapter in optics: in experiments with gamma rays at the Institut Laue- Langevin (ILL) in Grenoble they have proven that these extremely high- energy electromagnetic waves can be focused by lenses like conventional light =96 the researchers have thus refuted a fundamental assumption of theoretical physics that had been valid for decades. Their discovery will make a great many new applications possible in medicine and materials research, for example.
