During embryo development, patterns of protein concentration appear in response to morphogen gradients. These patterns provide spatial and chemical information that directs the fate of the underlying ...

Layered graphene oxide membranes (GOM) with densely packed sub-nanometer-wide lamellar channels show exceptional ionic and molecular transport properties. Mass and charge transport in existing ...

Gradients of molecular signaling factors play an essential role in numerous events in embryonic development, from patterning limb and organ formation to the intricate shaping of the brain and ...
