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.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
