Filamentous cyanobacteria represent a distinctive group of oxygenic photoautotrophs that exhibit a remarkable form of prokaryotic multicellularity. These organisms form elongated trichomes in which ...

Tight junctions are intercellular adhesion complexes in epithelia and endothelia that control paracellular permeability. This paracellular diffusion barrier is semipermeable: it is size- and ...

Alterations in peripheral myelin protein 22 (PMP22) gene expression are associated with a host of heritable demyelinating peripheral neuropathies, yet the function of the protein remains unknown.

Scientists found that messenger RNA (mRNA) molecules that carry genetic instructions to the far reaches of neurons in the brain tend to cluster together mostly because they are abundant, not because ...
