A bit reminiscent of the Terminator T-1000, a new material created by Cornell researchers is so soft that it can flow like a liquid and then, strangely, return to its original shape.

With their ultra short X-ray flashes, free-electron lasers offer the opportunity to film atoms in motion in complicated molecules and in the course of chemical reactions. However, for monitoring this motion, the arrival time and the temporal profile of the pulses which periodically illuminate the system, must be precisely known. An international team of scientists has now developed a measurement technique that provides complete temporal characterization of individual FEL (free-electron laser) pulses.

Harnessing laser light's ability to gently push and pull microscopic particles, researchers have created the fiber-optic equivalent of the world's smallest wrench. This virtual tool can precisely twist and turn the tiniest of particles, from living cells and DNA to microscopic motors and dynamos used in biological and physical research.

Chemiker der Universit�t Basel haben winzige Nanokugeln entwickelt, die das h�ufig eingesetzte Antibiotikum Cephalexin herstellen und lokal freisetzen k�nnen. Wenn es gelingt, solche Nanoreaktoren in medizinische Implantate einzubauen, liessen sich gezielt bakterielle Infektionen bek�mpfen, ohne dass der Wirkstoff �ber den ganzen K�rper verteilt wird.
