Ratios of mRNA transcript abundance between sample types are measures of biological activity. These measurements of differential gene expression are important to underpin new biological hypotheses and ...

Thirty years ago the world's longest running evolution experiment began when scientist Richard Lenski seeded 12 identical flasks with E. coli bacteria. Every subsequent day someone in the lab has ...

Simon Kirby and Hannah Cornish are watching evolution take place within the confines of their laboratory. But they are studying neither bodies nor genes; their interest lies in languages, and how they ...
