Tiny types of soil bugs already make many of the products we use in washing detergents, foods, and waste treatment, but scientists now hope that similar bacteria will also make the vaccines and drugs of the future, according to new research presented today (Tuesday, 07 September 2004) at the Society for General Microbiology’s 155th Meeting at Trinity College Dublin.
Researchers from the Institute of Cell and Molecular Studies at Newcastle University have successfully produced small quantities of a promising new vaccine for anthrax using Bacillus bacteria which have been modified to produce human medicines. “Many people already use enzymes produced by these bacteria to wash their clothes,” says Professor Colin Harwood of Newcastle University. “But the bacteria which make these enzymes, so useful for digesting dirt, have very efficient quality control systems which spot rogue proteins and enzymes and destroy them. This control mechanism stops us using these bacteria to make large quantities of the pure proteins we need for use in vaccines and other medicines.”
The scientists have spent the last ten years, working with a Europe-wide group of 11 research laboratories, discovering how bacteria move enzymes and proteins from inside their cells, where they are made, to the outside world, where they are needed.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

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...
