We've heard a lot about how important carbon and water are to life, but sulfur? Researchers think that sulfur may have actually been essential for organisms to make the transition from single-celled ...

Images of the multicellular development of the ichthyosporean Chromosphaera perkinsii, a close cousin of animals. In red, the membranes and in blue the nuclei with their DNA. The image was obtained ...

Stentor coeruleus is a giant unicellular, filter-feeding protist that uses the coordinated motion of its oral ciliary structure to generate feeding currents. These currents allow the organism to ...

A major event in the evolution of organisms on earth was the development of complex, multicellular life forms made of eukaryotic cells, which are thought to have come from prokaryotic cells. Studies ...

Marine bacteria normally seen as single cells join together as a “microscopic snow globe” to consume bulky floating carbohydrates. Close your eyes and imagine bacteria. Perhaps you’re picturing our ...

A team of scientists, led by the University of Sheffield in the UK and Boston College in the U.S., has found a microfossil in the Scottish Highlands which contains two distinct cell types and could be ...

Horodyskia, characterized by a string of beads with uniform size and spacing, is a kind of macroscopic fossil with a record extending from the early Mesoproterozoic Era (~1.48 Ga) to the terminal ...

Scientists have discovered the fossil of what may be the earliest multicellular animal ever found. Dating back a billion years, the microscopic fossil contains two distinct cell types, potentially ...
