Ticks transmit not only Lyme disease and tick-borne encephalitis, but also other diseases, such as neoehrlichiosis. A team of scientists from the University of Warmia and Mazury conducts research on the bacteria that cause this little-known disease in humans.
The functioning of the human body is the result of evolution. Normally, the human genome adapts to changes in the environment over thousands of years, but during the last 50 years the human life, including diet, has changed so radically that the general population has not yet had time to adapt and cope with lifestyle-related disease problems, believes Professor Carsten Carlberg.
A snapping shell, huge teeth and a long sticky thread help the predatory larvae of the thick shelled river mussel to lodge in the fish's gills and swim long distances. Polish researchers have solved the mystery of the strange jets of water that the female uses to lure fish - just like fly fishermen.
Non-English-language literature is the primary source of knowledge for nature and biodiversity policy makers in 37 countries surveyed by an international team of scientists. Publishing houses should take care of translating articles into many languages, the authors of the study believe.
Biologists from the University of Lodz are attempting to determine whether there will soon be a massive invasion of the hybrid crustacean Dikerogammarus villosus in Polish rivers. It threatens fauna because it feeds on fish eggs and displaces local species that live in European waters.
According to popular belief, any bear that smells honey cannot resist and will break into the apiary. Scientists have found that this is not true. They used DNA samples taken at the 'crime' sites to show that two thirds of the bears in the north-eastern Carpathians do not break into hives, despite the fact that many hives are still not properly secured.
