The “Superresolution” research network, founded by the German Ministry of Education and Sciences, demonstrated a new widefield microscopy technology with resolutions better than 20 nanometers. The method is based on special dyes, which’s fluorescence can be optically and reversibly switched on and off in aqueous solutions. The dyes are bond to cellular structures by using a functional group. By switching the dyes on and off, the fluorescence emission is separated in time until only those dye molecules fluoresce that have enough distance to allow their localization as single molecules. After several thousand switching cycles, a total image is constructed (dSTORM – direct stochastic optical reconstruction microscopy). Involved in the project were the work groups of Prof. Dr. M. Sauer and Prof. Dr. J. Mattay (University of Bielefeld, Germany ), Prof. Dr. K.-H. Drexhage (University of Siegen, Germany), Prof. Dr. J. Enderlein (University of Goettingen, Germany), and Prof. Dr. S. Hell (Max Planck Institute of Biophysical Chemistry, Goettingen, Germany).

The Twelfth Frontiers of Electron Microscopy in Materials Science, FEMMS2009, will take place from Sept. 27 – Oct. 2, 2009 at “Huis Ten Bosch” in Sasebo/Nagasaki in Kyushu Island, Japan. FEMMS is an international a biennial symposium series focused on the application of electron microscopy, primarily TEM, in the field of materials science. The conference contains a plenary talk, 9 sessions of invited talks and poster sessions of contributed papers. The sessions cover recent progresses and emerging trends, such as current instrument advances in TEM, SEM, HVEM and detecting systems, ultra-high resolution imaging and analysis, in-situ and ultra-fast analysis, 3-dimensional analysis, and so on. Dr. Akira Tonomura, a world renowned pioneer in the field of electron holography, will give a plenary talk as the distinguished lectureship award winner.

For his fundamental contributions to the field of optomechanics Prof. Tobias Kippenberg, leader of the independent Max Planck junior research group “Laboratory of Photonics and Quantum Measurements” at Max Planck Institute of Quantum Optics in Garching, Germany and tenure track assistant professor at the ETH Lausanne (EPFL) in Switzerland, is honoured with the Fresnel Prize in Fundamental Aspects of the European Physical Society (EPS). This award endowed with a prize money of €3000 is given by the “Quantum Electronics and Optics Division” of EPS biannually on the occasion of the “Conference on Lasers and Electro-Optics (CLEO) Europe”, held during the “World of Photonics” Congress in Munich, Germany. The prize for Tobias Kippenberg as well as the other EPS-awards will be presented in a ceremony on June 16, 2009.
