Strength in Diversity [PDF]

open access: yesCell Host & Microbe, 2014
In this issue of Cell Host & Microbe, Hammer et al. (2014) show that distinct, slow-growing bacteria have better in vitro and in vivo growth and virulence when cocultured than in isolation. They provide evidence that the observed inter- and intraspecies "complementation" involves the intercellular exchange of metabolites.

Strength in numbers [PDF]

open access: yesNature Communications, 2020
The robustness of science is best revealed when independent investigations of the same problem arrive at similar conclusions. At Nature Communications, we commit to disregard from our editorial evaluation any competing works that are published while a submission to our journal is under review or under revision by the authors.
