Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

A remarkably small bacterium containing fewer than 500 genes serves as the basis for one of the most detailed digital life ...

Study finds that large embryo cells divide step by step using a mechanical ratchet system, challenging the textbook idea of a ...

To model bacterial life, Thornburg and his colleagues turned to one of its simplest examples: a bacterial cell with a ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

HeLa cells are the most famous human cells in science. Discover how cervical cancer, HPV proteins, and bioethics shaped one ...

A hidden clue may explain why some mutated cells become cancerous and others don’t: how fast they divide. A new study from researchers at Sinai Health in Toronto reveals that the total time it takes ...

As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? By Amber Dance/Knowable Magazine Published Jul 7, 2023 6:00 PM EDT This article ...

Scientists seeking to unlock the secrets of cellular aging have identified a gene that triggers senescence, a phenomenon in which cells stop dividing. Senescence is a natural occurrence in the life of ...
