The growth environment driven ratio of ATP to growth rate, called absolute growth, determines the final population composition of Staphylococcus aureus and Pseudomonas aeruginosa when in co-culture.
Simulations and experiments on systems containing two different populations of microorganisms show that interactions that benefit at least one of the populations can lead to communities with stable compositions, and that strong cooperation between two populations can lead to communities in which both populations are mixed together.

Across 63 large US cities, street tree communities are shaped by climate, clustered by species, and made more similar between cities due to the presence of introduced species.
The metal-dependent protein phosphatase Nilkantha, a Drosophila PPM1A/B homolog, dephosphorylates Acinus thereby restraining starvation-independent autophagy.
Distinct antiviral signaling pathways, triggered by the aryl hydrocarbon receptor and Interferon-gamma, converge on CDK/cyclin repression, causing inhibition of viral DNA synthesis.

A newfound signaling enzyme that diverged from a protein family ubiquitous in bacteria provides mechanistic insights into how new signaling activity emerges to control distinct cellular function and physiology.
A new method for developing biosensors from ligand binding domains that have concentration-dependent and selective responses to small molecules in yeast, mammalian cells and plants.

The detection of low quantities of alkaloids in putatively nontoxic species of poison frogs sheds light on early evolutionary stages of chemical defense in animals.
