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.

High-precision measurement of the g-factor eleven times more precise than before / Results indicate a strong similarity between protons and antiprotons
The magnetic moment of an individual proton is inconceivably small, but can still be quantified. The basis for undertaking this measurement was laid over ten...
Heat from the friction of rocks caused by tidal forces could be the “engine” for the hydrothermal activity on Saturn's moon Enceladus. This presupposes that...
The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
