Team applies new techniques and sees surprises in cell division

Researchers at the California Institute of Technology have obtained the first high-resolution, three-dimensional images of a cell with a nucleus undergoing cell division. The observations, made using a powerful imaging technique ...

Oocytes: Going with the flow

Most cells rely on structural tethers to position chromosomes in preparation for cell division. Not so oocytes. Instead, a powerful intracellular stream pushes chromosomes far-off the center in preparation for the highly ...

Fishing games gone wrong

When an egg cell is being formed, the cellular machinery which separates chromosomes is extremely imprecise at fishing them out of the cell's interior, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, ...
