The presence of 'costly traits' useful for reproductive competition can have a positive effect on the population by purging harmful mutations or promoting adaptation variants, shows research of scientists from Poznań, Kraków and Ghent.
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.
According to Dr. Michał Żmihorski, director of the Mammal Research Institute of the Polish Academy of Sciences in Białowieża, monitoring of animal mortality in the Oder, as well as a professional methodology, would make it possible to determine the contamination mechanism faster and minimize its effects more efficiently.
