Intraflagellar transport: it's not just for cilia anymore.
Recently published information on the role of intraflagellar transport (IFT) polypeptides in vesicle exocytosis is reviewed, describing the formation of the immune synapse in nonciliated cells as an example. A hypothesis is detailed suggesting that all polypeptides which enter the cilium, both membrane and axonemal, do so in association, first, with cytoplasmic vesicles which exocytose adjacent...
متن کاملCilia-like beating of active microtubule bundles.
The mechanism that drives the regular beating of individual cilia and flagella, as well as dense ciliary fields, remains unclear. We describe a minimal model system, composed of microtubules and molecular motors, which self-assemble into active bundles exhibiting beating patterns reminiscent of those found in eukaryotic cilia and flagella. These observations suggest that hundreds of molecular m...
متن کاملSwimming like algae: biomimetic soft artificial cilia.
Cilia are used effectively in a wide variety of biological systems from fluid transport to thrust generation. Here, we present the design and implementation of artificial cilia, based on a biomimetic planar actuator using soft-smart materials. This actuator is modelled on the cilia movement of the alga Volvox, and represents the cilium as a piecewise constant-curvature robotic actuator that ena...
متن کاملAre dogs just like us?
Dogs have evolved to become the animal species most integrated with human society. Surprisingly, the origins and mechanisms of the remarkable co-evolution are still obscure and provide fuel for debates. Brain imaging studies showing up similarities and recent results implicating the hormone oxytocin also suggest that it makes sense to compare the social mind of dogs to our own. Michael Gross re...
متن کاملRepresenting others' actions: just like one's own?
Previous research has shown that observing others' actions can affect individual performance of the same actions. In the present study, we developed a new paradigm to investigate whether and how complementary actions at the disposal of another agent are represented and influence one's own actions. A spatial compatibility task was distributed among two people so that each participant took care o...
