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.

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
