Every year, in a selected country or region, Nature awards prizes for outstanding scientific mentoring. The competition this year is to be held in France. Two prizes, each of €10,000, will be awarded: for a lifetime of mentoring achievement, and for an outstanding track record at mid-career. The competition is now open. Details of the procedures and nomination forms can be found at http://www.nature.com/nature/mentoringawards/france. The closing date for nominations is 27 June 2011.
