This was news a few months ago but the Weihong Qiu lab in the Physics/Biophysics lab observed and reported that kinesin can walk backwards. It was previously thought that kinesin could only walk forward, in fact the Hoogenraad Lab video on kinesin even mentioned that it could only walk forward.
Here is the post on the Physics webpage; A biological motor that switches gears from forward to reverse
Also here is a funny animation for myosin on a single strand of actin by Erin Craig (CWU).
