The combination of statistical inference and perturbation experiments reveals that trans-generational inheritance of cell size and cell-cycle speed, coupled through a minimum-size checkpoint, shapes paradoxical cell-cycle correlations in lineage trees.
Oversized mammalian cells reduce their growth efficiency by activating global protein degradation, which functions in parallel with the cell size checkpoints, to promote cell size homeostasis.
Benzene mapping simulations of envelope protein rafts from six different flaviviruses reveal a conserved cryptic site whose cluster of ionisable residues is likely responsible for orchestrating pH-dependent conformational changes during fusion, thereby representing an attractive target for antiviral development.

Cells employ two strategies, adjusting both their cell cycle lengths and their growth rates in a size-dependent manner, to correct aberrations in cell size.
Yeast cell size homeostasis is not controlled by a G1-specific mechanism alone but is likely to be an emergent property resulting from the integration of several mechanisms that coordinate cell and bud growth with division.
