Tension stabilizes the attachment of microtubules to kinetochores during cell division in budding yeast, demonstrating how mechanical forces can modulate chromosome movement during replication. B.

Mitosis mechanism discovered;http://f1000.com/7353956?key=rtv49x8c8x7fnqz Researchers identify a new inhibitor of an enzyme that helps control mitosis by suppressing the activity of cyclin-dependent kinase 1, a key regulator of mitotic entry, revealing a completely novel component of the mitotic control system.
