Scientists at the John Innes Centre (JIC)and Institute of Food Research (IFR), Norwich, have today reported the discovery and use of a gene that may help protect plants and humans against disease. The gene (HQT) was identified in tomato and is responsible for producing an antioxidant called chlorogenic acid (CGA).
By increasing the activity of HQT, the scientists raised the levels of CGA in the tomato fruits and this helped protect them against attack from bacterial disease. CGA could also protect humans eating the tomatoes against degenerative, age-related diseases. This report is published online on 25 April in Nature Biotechnology and will be available in the June 2004 hard copy journal.
“Our tomatoes are doubly special” said Dr Cathie Martin (project leader at JIC). “They not only protect themselves against disease, but may benefit humans that eat them by protecting against age-related diseases. For us the excitement is that this adds to our understanding of how plants naturally protect themselves against stress and diseases, but in the long term it may be that this discovery leads to fruits that are better for us”.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
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.
