    Observation of long-range tertiary interactions during ligand binding by the TPP riboswitch aptamer

    Van K Duesterberg et al.
    The combined use of optical trapping and single-molecule FRET permits the study of riboswitch structure formation and conformational dynamics at the same time.

    Examining kinesin processivity within a general gating framework

    Johan OL Andreasson et al.
    A general framework for gating reveals that inter-head tension is not essential for coordinating kinesin stepping, and that neck-linker length is tuned to enhance processivity and velocity.

    Bidirectional helical motility of cytoplasmic dynein around microtubules

    Sinan Can et al.
    Unlike other cytoskeletal motors that produce torque in a specific direction, cytoplasmic dynein generates torque in either direction, resulting in bidirectional helical motility along microtubules.

    Single molecule mechanics resolves the earliest events in force generation by cardiac myosin

    Michael S Woody et al.
    Cardiac myosin converts energy from ATP into mechanical work by transitioning from a short-lived force-bearing state, to a post working stroke state before the release of inorganic phosphate.

    Direct measurement of conformational strain energy in protofilaments curling outward from disassembling microtubule tips

    Jonathan W Driver et al.
    The protofilaments that curl outward from a disassembling microtubule tip carry a large amount of strain energy and they can drive movement with an efficiency similar to conventional motor proteins.

    Point of View: Looking back and looking forward at Janelia

    Gerald M Rubin, Erin K O'Shea
    The Janelia Research Campus opened its doors 12 years ago: we describe the philosophy underpinning Janelia, the lessons learned, and plans for the future.
  1. Point of View: Unbridle biomedical research from the laboratory cage

    Garet P Lahvis
    Recent advances in technology now make it possible to carry out biomedical research on animals living in the wild, or captive animals living in naturalistic conditions.
