Some ichthyosaurs - the great predatory marine reptiles that lived in the times of the dinosaurs - had their snouts constantly open. That is how they exhaled the air collected inhaled when they emerged, determined palaeobiologists from the Polish Academy of Sciences. Until now, the breathing of these animals was a scientific mystery.
The Arctic ground squirrel is a rodent that spends most of its life in hibernation. Although it reduces its body temperature by approx. 40°C, it almost does not lose any fat-free mass. Research on its bacterial flora conducted, among others, by a Polish researcher, could help fight malnutrition in humans.
Dr. Tomasz Rewicz from the Department of Invertebrate Zoology and Hydrobiology, University of Lodz, will conduct research on biological diversity of invasive freshwater shrimps from Europe at the University of Guelph, Canada. The trip will be financed with a National Academic Exchange Agency grant.
Dragons exist not only in novels and legends. Mud dragons, or kinorhynchs, are miniature (1 mm or less) invertebrates. For millions of years, they have lived almost all over the world and everyone could meet them while walking on a sandy beach or sea bottom. A Polish researcher recently described eight new species.
