A parasitic worm accumulates epigenetic DNA tags over its lifetime.  

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

Bacteria that live in the digestive tracts of animals may influence the adaptive trajectories of their hosts.

Several labs have reported the formation of bacterial nanotubes under different, often contrasting conditions. What are these structures and why are they so hard to reproduce?

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

Find out which meetings have been canceled, postponed, or are going ahead as planned.

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

SOLVING REAL-WORLD PROBLEMS: MacArthur fellow Vonnie McLoyd's research combines concepts in socioeconomics, psychology, and anthropology. This year's John D. and Catherine T. MacArthur Foundation fellowships will help six scientists advance their cutting-edge, multidisciplinary projects that extend from the ocean depths to distant stars and planets. With grants of about $250,000 or more, the newly named fellows will be able to finance innovative-even maverick-research ideas that might otherwis

Christine Jacobs-Wagner's studies of a bacterial species have changed how scientists think about cell shape and polarity.
