In his new preprint Sami Al-Izzi (@samializzi, with Matthew Turner @TurnerSoftBio) shows that a simple membrane tube with unidirectional ion pumps forms a large vacuole that actively pump water out of the cell interior.

Active cellular water pump for osmoregulation. Unicellular organisms in fresh water need to actively pump water out to balance the large flux of water coming in due to osmotic pressure difference. No molecular water pumps are known, so this water pump must be supramolecular.

Our theoretical answer to these questions (and others) is out on Brilliant PhD work of @RomainRollin, co-supervised with @JFJoanny. More details in Romain’s thread.

How come the size of the nucleus generally scales with the size of the cell, although the nucleus is packed with DNA and surrounded by a relatively stiff envelop?.

How do cells maintain a constant protein density during growth, although the protein content is very small (1% in number of that of other osmolytes) and does not directly control cell volume? Why does density homeostasis break down at senescence, and transiently at mitotic entry?.
