Small minerals make strong bones

Small minerals make strong bones Selectins with a catch ot content simply with a good fit, evolution has apparently designed adhesion molecules that stick optimally only when tugged upon. This property, may stop leukocytes and platelets from lingering in stagnant backwaters in the blood where there is little or no flow. Blood is a medium dominated by flow and shear forces.

Oscillation helps to get division right.

A conserved feature of proliferating cells is their need to divide at the appropriate time and place using precise positioning mechanisms to ensure that each daughter cell has the same genetic complement as the parent, as well as the correct shape and size. In rod-shaped bacteria, division typically occurs precisely at midcell after the bacterial chromosome has replicated and segregated away fr...

KIF4 helps mitotic chromosomes get in shape

KIF4 helps mitotic chromosomes get in shape T hough chromosomes spend most of their time occupying amorphous territories in interphase nu-clei, we typically picture them as the compact X-shaped structures that form during mitosis. Chromosomes adopt this conformation to avoid becoming entangled as they segregate into daughter cells, but how mitotic chromatin condenses into the correct shape is u...
