Robust wrinkling pattern of the frilled dragon’s spectacular erectile ruff emerges from an elastic instability during homogeneous growth of the embryonic neck fold frustrated by its attachment to adjacent tissues.
The ability to follow single objects in 3D in a living organism with high spatiotemporal resolution opens new possibilities for quantitative biophysical studies of complex systems in their physiological context.
Two seemingly distinct behaviors in social C. elegans worms, namely aggregating into groups and swarming over food, are driven by the same underlying mechanisms.
A theoretical basis for the spatial regulation of protein aggregation shows how aggregates can partition preferentially into intracellular liquid compartments.
By distributing receptor-binding and receptor-destroying proteins asymmetrically on their surface, filamentous influenza A virus particles create a Brownian ratchet that facilitates their passage through mucus.
By using a specialized camera that corrects for eye blur, millions of single-blood-cells are imaged, and their speed measured, as they travel through the largest-to-smallest vessels of the retina.
Environmental heterogeneity can dramatically reduce the efficacy of selection and alter the neutral evolutionary dynamics in microbial range expansions.
