Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Until now, cells dividing by mitosis were thought to grow round and then split into two identical, ...

Cell division is one of the most fundamental processes of life. From bacteria to blue whales, every living being on Earth relies on cell division for growth, reproduction, and species survival. Yet, ...

Scientists have uncovered a new way embryonic cells divide when conventional mechanisms fail. Cell division underpins all ...

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 ...

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 ...

The filamentous bacterium Corynebacterium matruchotii splitting into multiple cells at once, a rare kind of cell division called multiple fission. C. matruchotii is one of the most common bacteria ...

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...

A simple mechanism could underlie the growth and self-replication of protocells - putative ancestors of modern living cells - suggests a study publishing September 3 in Biophysical Journal. Protocells ...
