Top: The cell pulls to maintain a fixed stretch in the gel. Middle: If the gel is externally stretched, the cell can reduce the force it exerts. Bottom: If the gel is alternately stretched and relaxed, the frustrated cell cannot "decide" how much force to exert. This results in the cell orienting perpendicular to the stretch direction

Dumpster Diving in Cancer Tissue Uncovers an Immune Evasion Mechanism

A stem cell–derived human embryo model at a developmental stage equivalent to that of a human embryo at day 12 has all the compartments typical of this stage. The top sphere contains the part that will become the embryo itself, capped by the amnion; the bottom sphere is the yolk sac; the interface between them is a critical structural feature of human embryonic development. The two spheres are encapsulated by a cellular layer that will become the placenta
