This paper identifies Replitrons, a new group of eukaryotic transposons encoding HUH endonuclease, and shows they are evolutionarily distinct from known transposons and viruses.

The paper infers the distribution of fitness effects of mutations in Chlamydomonas reinhardtii by analyzing frequency changes under experimental evolution and finds a leptokurtic distribution with equal positive and negative effects.

This study estimates the effects of positive selection on protein-coding and regulatory mutations in wild mice, finding stronger fitness impacts from coding mutations but higher frequency in regulatory regions.
