Alzheimer's and Parkinson's disease mechanisms are similar to prion diseases, says researcher
Neurodegenerative diseases such as Alzheimer's and Parkinson's are not infectious in the conventional sense, but growing evidence suggests they share the same underlying biology as prion diseases, says Professor Beata Sikorska of the Medical University of Lodz.

Parasites in 500-year-old burials reveal clues to diet and sanitation
Scientists have identified eight species of parasites in human burials from Chełm in eastern Poland dating back around 500 years, with most individuals showing evidence of multiple simultaneous infections, according to a study published in Archaeological and Anthropological Sciences.

Bison winter migration to farmland linked to changes in reproduction, study finds
European bison are increasingly migrating from forest habitats into agricultural areas during winter, where they feed on green crops such as rapeseed instead of dry hay, a shift scientists say may be affecting their reproductive biology.

Ancient dolphin-sized whale found in Poland rewrites early Cetacean evolution
Scientists have identified a 38-million-year-old whale jaw discovered in eastern Poland, marking the first confirmed find of an Eocene whale in the country and revealing that early fully marine cetaceans evolved into both giant predators and smaller, dolphin-like hunters.

Scientists discover new weapons against drug-resistant bacteria
Previously unknown mechanisms used by viruses that infect bacteria to overcome bacterial defences, have been discovered by researchers from Jagiellonian University. The findings, published in PLOS Biology could open new paths for therapies targeting antibiotic-resistant infections, the researchers say.
