A ribosome odyssey in mitochondria

Proteins make life and are made by ribosomes. In mitochondria, the repertoire of the mitoribosomal architectures turns out to be much more diverse than previously thought.

Novel major locus regulates beak evolution of ground tit

Classical quantitative genetics has found that most phenotypes are polygenic traits. Under this polygenic model, natural selection often acts on many loci simultaneously, resulting in the combination of a few loci with major ...

Evolutionary changes in the genetic code of yeasts

Yeasts are some of the most important microbes used in biotechnology. Saccharomyces cerevisiae, the type of yeast used for making bread and beer, is just one representative of more than 1,500 yeast species found around the ...

On the expansion threshold of a species' range

What stops a species adapting to an ever-wider range of conditions, continuously expanding its geographic range? The biomathematician Jitka Polechová, an Elise Richter Fellow at the University of Vienna, has published a ...
