"Important discovery at the Sapienza University in Rome, Italy" The narrowest visible light beam to date reported is observed in ferroelectric crystals. Shining light directly from a high-aperture microscope objective forms tiny light beams that instead of spreading because of diffraction, become smaller, down to spatial sizes that are below the optical wavelength, even below the ultimate limits of propagating light waves. The finding at the Sapienza University of Rome can lead to innovative high-resolution imaging schemes and suggests that light can acquire and effective mass. "
