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

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Scientists have elucidated the molecular mechanism by which LEM-3 cuts DNA bridges during cytokinesis. If DNA bridges persist between chromosomes during cell division, chromosomes are abnormally ...

Functional analysis of the LEM-3 protein and the roles of its domains using the C. elegans model. (A) Evidence shows that LEM-3 accumulates at DNA bridges remaining between daughter cells during the ...
