Chemists put biological catalysts to work in clean industrial solvents.
In a move towards cleaner chemical processing, researchers in Spain and France have worked out how to use enzymes as catalysts using two green solvents: one to dissolve the enzyme, the other to dissolve the materials it transforms.
In some industrial processes chemists have replaced polluting organic solvents, such as chlorine and benzene, with supercritical carbon dioxide. This is the liquid-like fluid that is made by putting carbon dioxide under moderately high pressure and at temperatures equivalent to a hot bath. Supercritical carbon dioxide dissolves many organic compounds used for chemical synthesis. It decaffeinates coffee, for example.

Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can’t manage. But how do you test a quantum computer to...
For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
