(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 ...

(Phys.org)—If asked to describe the differences between humans and frogs, a child might say that one hops and rib-its while the other walks and talks. If we ask that same child how to build a frog, they will probably need ...
Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed "living" nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control ...

Biological membranes are like a guarded border. They separate the cell from the environment and at the same time control the import and export of molecules. The nuclear membrane can be crossed via many tiny pores. Scientists ...
