Fontan et al. show that sequence divergence within introns can disrupt essential gene expression through defective splicing, providing a mechanistic link between rapid Y chromosome evolution and hybrid sterility.

Tiny, 45 base long RNA can make copies of itself

Self-copying RNAs may have been a key stop along the pathway to life.

McInerney proposes that genomes do not encode fixed functions but rather “probability distributions” over functional and phenotypic outcomes, and introduces “genomic perplexity” as a measure of gene-context incompatibility.

Giant DNA viruses encode their own eukaryote-like translation machinery, researchers discover

In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma that viruses lack protein synthesis machinery, and blurs the line between cellular life and viruses.
