We need to talk: How cells communicate to activate notch
During formation of multi-cellular organisms, cells need to talk to each other to make critical decisions as to what kind of cell to become, as well as when and where to become that cell type. The Notch signaling system allows ...

Wild blue yonder: Engineers tackle challenges of hypersonic flight
(Phys.org) -- Aeronautical engineers believe hypersonic planes flying at seven to 15 times the speed of sound will someday change the face of air and space travel. That is, if they can master such flight's known unknowns.
