Dr Bensimon also expects that molecular combing will come in handy for those mapping the human genome.

But Dr Bensimon's work has certainly made the task of disentangling tiny molecular structures less hair-raising than it used to be.

In recent experiments carried out by Chiara Conti and other members of Dr Bensimon's team, molecular combing was used to identify a genetic defect responsible for cancer of the kidney, which is notoriously difficult to diagnose in its early (and therefore treatable) stages.
