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 ...

Scaling up from one cell to many may have been a small step rather than a giant leap for early life on Earth. A single-celled organism closely related to animals controls its life cycle using a ...

The diversity of unicellular eukaryotes covered in the study, with their nucleus (blue) and microtubule cytoskeleton (magenta) stained. These organisms are so distantly related to each other as they ...

Multicellular organisms (animals, plants, humans) all have the ability to methylate the cytosine base in their DNA. This process, a type of epigenetic modification, plays an important role in ...

MicroRNAs (miRNAs) — a class of small RNAs with a role in the regulation of gene expression — had until now been found only in multicellular organisms. Now, Wang, Qi and colleagues provide the first ...

At some point, organisms changed and grew from a single cell into one made up of many cells. But how that happened is not well understood. New work by graduate candidate Jonathan Featherston of the ...

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 ...

Scientists discover microRNAs in the unicellular green alga, Chlamydomonas reinhardtii. This is the first finding of microRNAs in a unicellular organism. An international collaboration of researchers, ...

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 ...

How low can worms go? According to a new study, at least 0.8 miles (1.3 kilometers) below the Earth's surface. That's the depth at which scientists discovered a new species of worm, dubbed ...

The genome sequencing of the algae, Gonium pectorale, provides valuable clues into how and why single cells live together in groups -- one of the earliest steps on the path to a multicellular ...
