Biomarkers are used to predict quantitative metabolite concentration profiles in human red blood cells

A set of extracellular biomarkers has been recently identified that reliably defines the qualitative state of the metabolic network throughout this metabolic decay process. Yurkovich et al. extend the utility of these biomarkers by using them to quantitatively predict the concentrations of other metabolites in the red blood cell.

Feedback between motion and sensation provides nonlinear boost in run-and-tumble navigation

Many bacteria navigate gradients by alternating periods of straight motion (runs) with random reorientation events (tumbles). Control of the tumble probability is based on previously-encountered signals. Long et al. show that there is an operating regime within the organism’s internal parameter space where run-and-tumble navigation can be extremely efficient.
