A new electron microscope invented at Michigan State University allows scientists to zoom in on the movements of atoms and molecules. Electron microscopes allow scientists to see the structure of microorganisms, cells, metals, crystals and other tiny structures that weren't visible with light microscopes. But while these images have allowed scientists to make great discoveries, the relationship between structure and function could only be estimated because of static images. In the 1990s, researchers added a fourth dimension - time - by using a laser to capture images of gaseous molecules as they were reacting.

The Basque Research Centre CIC microGUNE is researching new applications for the technology known as femtosecond laser. This kind of laser allows the processing of materials with an unachievable precision for other techniques. Working inside transparent materials without damaging their surface, making more sensitive sensors for chips than the present ones, or treating metals in a more precise way than the conventional lasers are some of its possible applications.

For the first time, researchers have produced a coherent, laser-like, directed beam of light that simultaneously streams ultraviolet light, X-rays and all wavelengths in between (see video). One of the few light sources to successfully produce a coherent beam that includes X-rays, this new technology is the first to do so using a setup that fits on a laboratory table.

Newport's WEU-02 wavelength extension unit is designed to expand the capability of femtosecond lasers. Through a series of user controls, the WEU-02 can be configured for use in various spectroscopy, imaging, and pump-probe applications. It can also be integrated into two-photon microscope set-ups to add modalities for enhanced imaging capabilities.

The world's most accurate metronome keeps stroke to an incredible 10 quintillionth of a second. The device enables slow-motion pictures from the world of molecules and atoms, scientists from the Center for Free-Electron Laser Science (CFEL) in Hamburg, Germany, and the Massachusetts Institute of Technology (MIT) report. The metronome, an ultrashort pulse laser, acting as an optical flywheel, is currently the most precise clock generator on short time scales, writes the research team headed by DESY scientist Prof. Franz X.
