Simulations of the unliganded human hemoglobin tetramer, which for the first time yield a thermodynamically stable system, cast doubts on the use of standard solvent box sizes for molecular dynamics studies of biological macromolecules.

Analysis of experiments on bacteria suggests that the dependence of cell size on growth rate is not an adaptation but a causal consequence of a regulatory mechanism that controls DNA replication.

New methods to directly visualize Rho GTPases reveal how a protein called RhoGDI regulates the activity of these 'molecular switches' at the plasma membrane.

Computer simulations of model proteins with sticker-and-spacer architectures shed light on the formation of biomolecular condensates in cells.

Multi-modal MRI techniques have identified biomarkers that could help to predict whether someone will develop epilepsy.

Why does the human regulatory system, which evolution tuned for small satisfactions, now constantly demand 'more'?

Bar-headed geese lower their flight metabolic rates to fly in low-oxygen conditions.
