Research news from the Journal of the Science of Food and Agriculture
15 December 2003: The presence of E.coli bacteria, found in foods such as egg white and apple juice, is a major public health concern. The bacteria have, in the past, been inactivated by heat pasteurisation -- which can affect flavour and consistency. New evidence published in the Journal of Science of Food and Agriculture, however, suggests that UV irradiation may prove to be a better and more cost effective method of eliminating the risks posed by E. coli bacteria.
Researchers working in Canada discovered that an optimal UV irradiation system can be developed for individual food products, taking into account the UV transmittance of each product. With the optimal fluid depth and UV dose, significant decrease in active E. coli bacteria was observed in both apple juice and liquid egg white.

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...

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...
