The information theory of aging
Abstract Information storage and retrieval is essential for all life. In biology, information is
primarily stored in two distinct ways: the genome, comprising nucleic acids, acts as a …

Evolution of the SARS-CoV-2 mutational spectrum
SARS-CoV-2 evolves rapidly in part because of its high mutation rate. Here, we examine
whether this mutational process itself has changed during viral evolution. To do this, we …
