Next-generation sequencing has identified scores of new microorganisms, but getting even abundant bacterial species to grow in the lab has proven challenging.

p53 is possibly the most important protein for maintaining cellular function. Losing it is synonymous with cancer.

Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.

Everyone knows that the first genome sequencing projects took years of work and represent the combined product of tens of thousands of individual fragments.

In the final chapter of his book on the origins of vertebrate sex, author and paleontologist John Long pays homage to the humble placoderm, which got the erotic ball rolling.

While regeneration has long been the domain of colonial tunicates, a solitary species of sea squirt was able to regenerate into multiple, fully functional individuals within a month of being cut up.

By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.

A device dubbed the “mother machine” enables real-time observation of mutagenesis in single bacterial cells.  

A study finds that fast-growing species are stymied by narrow gaps, while slower-growing species can pass through and continue extending.
