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 ...

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 ...

The world is full of unusual unicellular organisms and microbes, many of which have not been discovered yet. In 2017, scientists identified a single-celled marine organism called Chromosphaera ...

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 human gut microbiome is known to have a significant influence on many aspects of our health. Usually, when people think of the gut microbiome, they think of the many bacterial species that live ...

Groundbreaking fossils unearthed in China suggest that multicellular organisms arose earlier than scientists previously thought. The fossils, of what may be an ancient type of photosynthetic alga, are ...

Cooperation is a classic solution to hostile environments that limit individual survival. In extreme cases this may lead to the evolution of new types of biological individuals (e.g., eusocial ...

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 ...

A new study led by researchers at Yale and McGill University reveals how fluctuations in the Earth’s oxygen levels over 700 million years ago may have set the stage for the diversification of ...
