When a cell spreads out or changes its shape to adapt to its environment, the transport rate of proteins between the nucleus and cytoplasm changes. Previously, scientists assumed this change was ...

According to a new theoretical model, in cell protrusions and cargo-transporting motor proteins often get in each other's way. The upshot is that freely diffusing proteins reach the leading edge ...

Defying one of biology’s more persistent dogmas, a potassium channel combines functions once thought to be invariably asunder. This channel, which is found in common bacteria, incorporates a subunit ...

Plant and animal cells have a complex traffic system within them. This transport network links cellular compartments much like the traffic network that connects different districts in an urban ...

Unlike many other organisms, plants can't simply run away from environmental conditions that change for the worse. Nonetheless, plants have the ability to react to environmental effects. These ...

HHMI researchers suggest that defective cell transport may play a role in Alzheimer’s disease. Over the last few years, scientists have been successful in identifying genes implicated in Alzheimer’s ...
