Over the centuries, humans have deprived animals of large areas of their natural habitats. However, some of them have adapted perfectly to the new conditions they find in urban agglomerations, says the head of Department of Vertebrate Ecology and Zoology of the University of Gdańsk, Professor Włodzimierz Meissner.
'We need to free our cities of concrete, because it will soon become unbearable,’ says Professor Tomasz Jurczak from the University of Lodz. According to ecohydrologists, this is the last moment to change our way of thinking about water and greenery in cities as critical infrastructure.
Inside human cells, the helical DNA strand twists further and is completely different from the familiar double helix. At very small scales, the behaviour of DNA is determined by elastic forces. Scientists show how to study the elastic properties of DNA using hydrodynamic measurements. Discovering the shapes of DNA mini-circles was described by an international research team with the participation of Polish scientists.
Bees evolved from carnivorous ancestors. In the course of evolution, they had to adapt to a plant-based diet. The problem is that the nectar and pollen that make up their food have such a high of potassium to sodium ratio (K:Na) that it can negatively affect the development and health of bees. Polish researchers analysed the consequences of the situation.
‘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.
