Latest Molecular motor Stories
Friction is the force that resists the relative motion of two bodies in contact. The same is true on the nanoscale: Molecular motors have to fight the friction created between them and their tracks.
Cells rely on tiny molecular motors to deliver cargo, such as mRNA and organelles, within the cell. The critical nature of this transport system is evidenced by the fact that disruption of motors by genetic defects leads to fatal diseases in humans.
Chemists at New York University and Harvard University have created a bipedal, autonomous DNA "walker" that can mimic a cell's transportation system.
Even within cells, the left hand knows what the right hand is doing.
An international team of scientists led by the University of Leeds has shed new light on the little-understood motor protein called dynein, thought to be involved in progressive neurological disorders such as motor neurone disease.
Max Planck scientists shed light on transport mechanism in cells
While the human body has plenty of specialized molecular motors and machines powering the mechanical work necessary for cells to function properly, scientists themselves face many hurdles as they try to create their own molecular machines in the laboratory.
