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 ...

When a human cell prepares to split into two daughter cells, it must first construct a tiny internal machine called the mitotic spindle—a structure of protein fibers that physically pulls chromosomes ...

What we have found is that one of its subunits, Pfk2, also functions as an RNA regulator that helps to coordinate when cells divide. "This is not about energy production—we propose that the enzyme ...

Understanding the origin of life requires addressing a collection of overlapping scientific questions. We’ve made a lot of progress toward explaining how simple chemicals present on an early Earth ...

In the fly gut, stem cells keep the balance of cell types by undergoing eight rounds of cell division to form absorptive cells, then one round to form secretory cells. Read the paper: Intestinal stem ...

In a tale of identities as divergent as "The Prince and the Pauper," a well-known cancer-causing gene also influences cells in a zombie-like state meant to prevent cancer. Subscribe to our newsletter ...
