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.

A team of biologists has unraveled the biochemistry of how bacteria so precisely time cell division, a key element in understanding how all organisms from bacteria to humans use their biological clocks to control basic cellular functions.

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.

A NASA-funded study suggests humans might not exist today if not for the ancient fusing of two microscopic, single-celled organisms called prokaryotes. Biologist James Lake of the UCLA Center for Astrobiology compared proteins present in more than 3,000 different prokaryotes -- a type of single-celled organism without a nucleus -- and discovered two major classes of relatively simple microbes fused together more than 2.5 billion years ago. That endosymbiosis, or merging of two cells, he said,...

Humans might not be walking on Earth today if not for the ancient fusing of two microscopic, single-celled organisms called prokaryotes, NASA-funded research has found.

UCLA biochemists and colleagues have answered an important question about the structure of microcompartments — the mysterious molecular machines that seem to be present in a wide variety of pathogens and other bacteria.
