The influenza (flu) virus is constantly undergoing a process of evolution and adaptation through acquiring new mutations. Scientists at St. Jude Children's Research Hospital have added a new layer of ...

New research challenges the long-standing idea that most fixed genetic mutations are neutral. For many years, scientists studying evolution have believed that most genetic changes influencing how ...

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and ...

(SALT LAKE CITY) – In an environment where others struggle to survive, Tibetans thrive in the thin air on the Tibetan Plateau, with an average elevation of 14,800 feet. A University of Utah led ...

Nuclear mutation rates were determined through genome sequencing of whale trios (mother, father, and calf). The mutation rate was calculated by counting nucleotide base changes (i.e. mutations) ...

Zika virus (ZIKV) caused millions of infections during its rapid and expansive spread from Asia to the Americas from 2015 to 2017. Here, we compared the infectivity of ZIKV mutants with individual ...

Natural pathogenic bacteria populations can harbour mutator alleles (with high mutation rates) that may offer a selection advantage. In the March 30 Science, Giraud et al. describe a model to ...

Highly pathogenic avian influenza (HPAI) has entered a concerning new phase, demonstrating its adaptability by spreading from birds to dairy cows. This marks the second recorded spillover of HPAI into ...
