An organism grows and repairs its body using a form of cell division known as mitosis. To divide, a cell must replicate the chromosomes, which carry the DNA (the instructions needed to build the body) ...

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 ...

A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...

This figure presents a modern tree of Life, highlighting eukaryotes (organisms with complex cells) based on genome-scale analyses from Valt et al. (2025). The newly identified and ancient supergroup ...

If you took high school biology, you probably learned about cell division: a crucial process in all life forms officially called mitosis. For over one hundred years, students have learned that during ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single cells and forming multicellular structures. This ability to alternate ...

Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...

A group of researchers has won a large science prize for a discovery not quite two decades in the making. It was long thought that only simple microbes had mastered a chemical conversion reaction that ...

Oxygen played a key role in the evolution of complex organisms, according to new research published in BMC Evolutionary Biology. The study shows that the complexity of life forms increased earlier ...
