Mimicking nature at the nanoscale: Selective transport across a biomimetic nanopore
Researchers at Delft University of Technology and the University of Basel have established a biomimetic nanopore that provides a unique test and measurement platform for the way that proteins move into a cell's nucleus. In ...

Come on in: Nuclear barrier less restrictive than expected in new cells
When it comes to the two basic types of cells, prokaryotes and eukaryotes, compartmentalization is everything. Prokaryotes are evolutionarily ancient cells that only have a membrane surrounding their outer boundary, while ...

Researchers construct a device that mimics one of nature's key transport machines
(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 ...
