Brittle stars, animals with five-segment radial (pentaradial) symmetry, lived millions of years ago in the territory of present-day Poland. They survived, although today they can only be found in high salinity waters. Fossil species of these agile echinoderms found in Kujawy and the Krakow-Częstochowa Upland have been described by scientists from Warsaw.
Roe deer, not red deer, is the main source of food for wolves in Roztocze and the Solska Forest, according to research by Polish scientists. The domination of roe deer in the diet of these predators has persisted for two decades. The wild boar currently has the second place in wolves' menu.
Transposons, known as jumping genes, can 'cut themselves out' from the DNA, and then paste into its another, often precisely selected place. Scientists view them as the future of genome editing. Polish researchers have recently completed a difficult task: they described the key protein related to the action of the transposon when this is 'getting ready to jump'.
The widely held assumption that any important scientific information would be available in English underlies the underuse of non-English-language science across disciplines. Meanwhile, they often provide important information on the protection of biodiversity in the world, says Dr. Joanna Kajzer-Bonk, a biologist from the Jagiellonian University.
