Researchers in the Netherlands have investigated the molecular structure of plant proteins that must provide alternatives for the animal proteins in our food over the next 10 years. They discovered that proteins with a similar chemical structure behaved differently after heating. The behaviour of the proteins after heating plays an important role in the development of a new type of meat substitute product.
Francesca O’Kane used various proteins from peas and soya for her research. After heating the plant proteins formed a gel from which she could deduce the structure of the proteins after heating. Although the pea protein legumin has a structure which is very similar to the soya protein glycinin, O’Kane discovered clear differences between the two proteins after heating. The gel of the soya protein could be repeatedly heated without the gel losing its strength or flexibility. This was not possible with the pea protein gel, due to its unusual spatial structure. Upon repeated heating this gel became increasingly stiff.
The greatest stumbling block in the design of foodstuffs using non-animal proteins is the unpredictability of the final product’s structure, the so-called texture. O’Kane used several proteins from peas to map the behaviour of plant proteins. She followed the molecular structure of the proteins in three stages: the unfolding during heating, the aggregation after heating and the eventual formation of a network, in which the proteins formed a gel. The formation of the gel provides a model for how proteins aggregate.

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.
