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

Another theory held that the forces between two particles falls off exponentially in direct relationship to the distance between two particles and that the factor by which it drops is not dependent on ...

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 cells in our bodies move in groups during biological processes such as wound healing and tissue development – but because of resistance, or viscosity, those cells can’t just neatly glide past each ...
