Timing and properties of spontaneous knotting in the
macromolecular world
The scientific journal Macromolecules dedicates the cover of
this month's issue (available online from June 11th) to a research coordinated
by Cristian Micheletti of the International School for Advanced Studies
(SISSA). Micheletti and his colleagues,
that include Luca Tubiana (a former SISSA student, now
working at the Josef Stefan Institute of Ljubljana) and Angelo Rosa (a
researcher at SISSA) simulated the dynamics of the movements with which a
polymer tends to knot.
