The history of cultivated plants in Finland stretches back some 3,500 years. Cultivated plants usually arrived in Finland from elsewhere with new settlers. Landraces were still widespread in the early part of the 20th century, but then improved varieties produced in plant breeding programmes began to gain ground in the 1920s. As a consequence, the landraces, which were well adapted to local conditions, are no longer grown to any large extent, and thus they no longer contribute to the diversity of our grain fields. The characteristics of the landraces are little known and they are in limited use in agriculture today.
It is essential for food safety now and in coming generations that we can safeguard the gene pool. Because we cannot know what we may need in the future, it is important to maintain the widest possible selection of genetic material for the use of farmers, researchers, plant breeders and other users. Landraces of both plants and animals are a part of our invaluable heritage and the history of our nation. The most common way of preserving genetic materials is to deposit seeds in gene banks. Apart from that, the most natural preservation method would be to cultivate plants in their original environment. Subsidies are available for the preservation of landraces and old commercial varieties of cereals.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
