‘I have seen the light side and dark side of science during the pandemic. I deliberately devote myself to science, not to business, because I do not want to lose my research freedom and independence,’ says Professor Marcin Drąg, chemist and creator of a laboratory used, among other things, to do research on the coronavirus.
Scientists from the University of Agriculture in Krakow are working on the rapid detection of testicular dysfunction in dogs. Breeders of reproductive purebred dogs need diagnostic analyses. A cheap and reliable test will enable early treatment of animals or other appropriate breeding decisions.
Research by an international team with the participation of Polish scientists leads to a better understanding of diseases related to the disrupted function of mitochondria, cellular 'power plants'. Long-chain fatty acids are essential for the proper course of cellular respiration, researchers from the Faculty of Physics of the University of Warsaw have found.
Vegetation acts as a natural filter for sediments and pollutants, supporting the self-purification of water. A scientist from the Institute of Geophysics of the Polish Academy of Sciences points out that this is of particular importance in agricultural ditches, because plants retain residues of fertilizers and plant protection products.
Vesicles produced by endophytic bacteria act as messengers with a specific cargo load. Using this mechanism, it is possible to stimulate the plant to grow or provide it with tools to defend against pathogens. Research is conducted at the University of Silesia and the Maria Curie-Skłodowska University.
Beetles' wing-cases (elytra) are one of the most important adaptation achievements of this group of insects, which ensured its enormous evolutionary success. A research team including a Polish scientist published an extensive analysis of the evolution, modification and various functions of these structures in Biology Letters.
The corpus luteum plays an important role in early pregnancy through the production of progesterone, an essential hormone needed for the proper development of pregnancy. Scientists from the Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences in Olsztyn discovered that this gland also secretes a protein called prokineticin 1, which increases lifespan and stimulates the functions of the corpus luteum.
