Scientists solve breeders' problem of dog infertility
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.

Long-chain fatty acids essential for cellular respiration
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.

Shifting bird ranges in Europe due to climate change, but geographical barriers 'mediate' this movement
Climate change is shifting bird ranges across Europe, but geographic barriers 'mediate' their movement. An international team of scientists with the participation of Polish researchers described this phenomenon in the Proceedings of the National Academy of Sciences.

Less fertilizer residues in rivers thanks to plants in agricultural ditches
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.

Bacteria with potential for biological vaccines for plants
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.

Urban green space can mitigate the effects of climate change, say experts
Scientists investigate how 'green' our cities are. The results of their research can help effectively use urban green spaces to mitigate the effects of climate change. Shaping green infrastructure is one of the five topics investigated by experts in the 'City with Climate' project.

Wing-cases responsible for great evolutionary success of beetles
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.

Scientists discover new mechanism that supports corpus luteum function
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.

Researchers re-examine ancient crocodylomorph from Załęcze Wielkie
Scientists have re-examined the remains of a prehistoric marine reptile found in the 20th century in the village of Załęcze Wielkie (Łódź province). This distant relative of modern crocodiles was about four metres long and had a visible jaw injury, which it probably suffered in the first years of its life.
