Each time a cell divides -- and it takes millions of cell divisions to create a fully grown human body from a single fertilized cell -- its chromosomes have to be accurately divvied up between both daughter cells.

Scientists call it LUCA, the Last Universal Common Ancestor, but they don't know much about this great-grandparent of all living things.

Remote lochs along the west coast of Scotland are turning up new evidence about the origins of life on land.

An Ohio State University molecular biologist leveraged a supercomputer to help better define the family tree of a group of enzymes that have been implicated in a wide range of human diseases and are important targets for anti-cancer therapies.

Although they are present almost everywhere, on land and sea, a group of related bacteria in the superphylum Planctomycetes-Verrucomicrobia-Chlamydiae, or PVC, have remained in relative obscurity ever since they were first described about a decade ago.

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 the more complex eukaryotes have an outer membrane and membrane bound compartments within the cell. Perhaps most notable is the double layered membrane that surrounds the nucleus, the cellular compartment which houses the cell's genetic material.

Scientists have suspected that the three known domains of life -- eukaryotes, bacteria, and archaea -- branched off and went their separate ways around three billion years ago. But pinning down the time of that split has been an elusive task.

UCLA biochemists reveal the first structural details of a family of mysterious objects called microcompartments that seem to be present in a variety of bacteria. The discovery was published Aug. 5 in the journal Science.
