Double-stranded RNA does not always mean inflammation. New look at immunity

Until now, the consensus was that any effective cellular response to dsRNA would inevitably lead to inflammation. However, research conducted by a team of scientists, including researchers from the University of Warsaw, has shown that that the matter is much more complicated. Cells can respond to threats without triggering an inflammatory reaction.

Mussels in decline, or how superorganisms are dying out

Mussels are extraordinary organisms that have dominated aquatic ecosystems for millions of years - from the depths of the oceans to the sources of streams. They are long-lived, with some species living for hundreds of years. Despite this, their numbers have been decreasing drastically in recent decades. New research by Polish scientists - Tadeusz Zając, PhD, and Katarzyna Zając, PhD, professors at the Institute of Nature Conservation of the Polish Academy of Sciences - sheds light on the causes of this phenomenon.
