Genome dilution limits cell growth by modulating the activities, rather than the concentrations, of RNA polymerases and ribosomes, and is accompanied by changes in proteome composition.
Carbon dynamics and the relative availability of key nutrients during litter decomposition are modified by changing biodiversity in the Earth’s forests.

The reliance on food composition databases for the assessment of dietary intake is unreliable and results in a large bias when investigating the associations between diet and disease risk.
An ECF-type transporter serves as broad-spectrum heme iron scavenger and allows an opportunistic pathogen to use multiple eukaryotic hemoproteins to overcome nutritional iron-limitation.

Nutrient limitation elicits differential responses in cells lacking the tumor suppressor PTEN and in normal cells, resulting in hyperplastic overgrowth of PTEN mutant tissue independent of additional mutations.
