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.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
