Researchers uncover new mechanism of ion transport in nanofiltration membranes

A research team discovered a counter-ion competition mechanism that explains the superiority of negatively charged nanofiltration membranes in separating lithium and magnesium ions. This finding provides critical insights for designing next-generation NF membranes with tailored ion selectivity.

Cellular liquid droplets can cut membranes

Scientists have found that biomolecular condensates can cross membranes without specialized cutting proteins, a process called wetting, which is essential for plant survival. The study shows that these liquid droplets can exert large capillary forces on membranes, cutting them in two and enabling material exchange between cell parts.

Massive endocytosis in cells

Scientists identified a previously unknown mechanism for massive endocytosis (MEND) in cells, where up to 75% of the cell plasma membrane can be reversibly engulfed. MEND preferentially targets low-ordered, cholesterol-containing membrane domains.
