Random sequences are an abundant source of bioactive RNAs or peptides
TL;DR: Contrary to expectations, it is found that random sequences with bioactivity are not rare and may become an effective new source of molecules for studying cellular functions, as well as for pharmacological activity screening.
Spore-autonomous fluorescent protein expression identifies meiotic chromosome mis-segregation as the principal cause of hybrid sterility in yeast.
TL;DR: The results demonstrate that sequence divergence is not only associated with the sterility of hybrids formed between distantly related species but may also be a direct cause of reproductive isolation in incipient species.
Ribosome Provisioning Activates a Bistable Switch Coupled to Fast Exit from Stationary Phase.

TL;DR: It is shown that pyrimidine limitation triggers an increase in ribosome biosynthesis and that switching is caused by competition between ribosomes and CsrA/RsmA proteins for the mRNA transcript of a positively autoregulated activator of colanic acid biosynthesis.

Diminishing Returns on Intragenic Repeat Number Expansion in the Production of Signaling Peptides.
TL;DR: It is shown that the number of mature-pheromone-encoding repeats in the yeast α-mating-factor gene MFα1 varies considerably between closely related isolates of both Saccharomyces cerevisiae and its sister species SacCharomyces paradoxus, and multiple explanations are investigated for this pattern of diminishing returns.
Independent evolution toward larger body size in the distinctive Faroe Island mice
TL;DR: In this article, the authors have mapped the genetic basis of body size variation by making a genetic cross between mice from the Faroe Islands, which are among the largest and most distinctive natural populations of mice in the world, and a laboratory mouse strain selected for small body size.
