(PhysOrg.com) -- To help protect its genes, a cell is highly selective about what it allows to move in and out of its nucleus. Yet that choosiness is regulated by just a thin barrier, perforated with tiny transport machines ...

When a cell spreads out or changes its shape to adapt to its environment, the transport rate of proteins between the nucleus and cytoplasm changes. Previously, scientists assumed this change was caused by a shift in the size ...
