    Notochord vacuoles absorb compressive bone growth during zebrafish spine formation

    Jennifer Bagwell et al.
    Live imaging and genetic analyses revealed that notochord vacuoles play a critical role in spine morphogenesis by absorbing vertebral bone growth, thus implicating notochord mechanics in congenital scoliosis.

    High-speed motility originates from cooperatively pushing and pulling flagella bundles in bilophotrichous bacteria

    Klaas Bente et al.
    Bacteria reach swimming speeds of several hundred body lengths per second and change direction in less than 5 ms by using coordinated flagella bundle agitation.
