It was a 3D puzzle with over 1000 pieces, with only a rather fuzzy outline as a guide. But scientists at EMBL have now put enough pieces in place to see the big picture. In a study published today in Science, they present ...

(Phys.org)—Two teams of researchers taking different approaches have successfully mapped and diagramed the nuclear pore complex (NPC)—protein complexes that make up the pores in the nuclear envelope that allow or prevent ...
Long before animals evolved from sponges, and before plants evolved out of algae, there was a pivotal event that allowed complex, multicellular organisms to arise: the development of the nucleus in single-celled organisms. ...

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 ...

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 ...

(PhysOrg.com) -- For perhaps 1.8 billion years after life first emerged on Earth, a sort of evolutionary writer’s block stalled the development of organisms more complicated than single cells. Then, a burst of experimental ...
