The occurrence of active water transport (net transport against a free energy gradient) in photosynthetic organisms has been debated for several decades. Here, active water transport is considered in ...

Humans like to think that being multicellular (and bigger) is a definite advantage, even though 80% of life on Earth consists of single-celled organisms—some thriving in conditions lethal to any beast ...

Also known as blue-green algae, cyanobacteria are a special class of bacteria that are able to perform photosynthesis. In evolutionary terms, they are ancient. Their predecessors - which first emerged ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

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 ...

Researchers have discovered that environments favoring clumpy growth are all that’s needed to quickly transform single-celled yeast into complex multicellular organisms. To human eyes, the dominant ...

When the slime mold Dictyostelium discoideum runs out of food, sulfur limitation drives its development from a unicellular to a multicellular organism. Researchers now present the nutrient signaling ...

The transition from single-celled organisms to multicellular life was a pivotal moment in evolutionary history, marking the emergence of complex communication systems that allow cells to coordinate ...

The chicken-or-egg mystery has long puzzled humanity, posing a seemingly unanswerable question about the origins of life and ...

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 ...
