Learn how one-celled organisms, or single-celled organisms, helped build complex life.

Prototaxites are something of a prehistoric mystery. They were the first giant organisms on land, towering over ancient ...

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments discovered gene fragments that indicated a new and previously undiscovered form ...

Researchers have discovered that a single-celled organism, a close relative of animals, harbors the remnants of ancient giant viruses woven into its own genetic code. This finding sheds light on how ...

Scientists have discovered a single-celled organism in the hot springs of Lassen Volcanic National Park, which is not only the first eukaryote to grow at 63 degrees Celsius (approximately 145 degrees ...

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 ...

An artist’s depiction of an Asgard archaeon, based on cryo-electron tomography data: the cell body and appendages feature thread-like skeletal structures, similar to those found in complex cells with ...

New work shows that physical folding of the genome to control genes located far away may have been a critical turning point for life on Earth. For evolutionary biologists, what most distinguishes the ...

Bacterial cells can 'remember' brief, temporary changes to their bodies and immediate surroundings, a new study has found. And, although these changes are not encoded in the cell's genetics, the cell ...

In his laboratory at the University of Poitiers in France, Abderrazak El Albani contemplates the rock glittering in his hands. To the untrained eye, the specimen resembles a piece of golden tortellini ...

Researchers at the University of Tokyo created a 5mm tall doll composed of living cells, in an experiment to create 3D living biological structures. It’s cute and kinda gross at the same time. The ...
