Four teams will race tiny vehicles made of a single molecule at The National Center for Scientific Research (CNRS) in Toulouse on April 28. The competition will be broadcast live on YouTube for fans of both motorsports and cutting-edge science.Aside from putting on a spectacle, the competition is aimed at demonstrating the growing capabilities of so-called molecular machines. Three European academics won the 2016 Nobel Prize in chemistry for demonstrating the ability to design and build devices at the molecular level that work like traditional machines by converting input energy into mechanical work.

Christian Joachim, a senior researcher at CNRS and director of the NanoCar Race, told Live Science the organizers were keen to maintain the innovative spirit of early motorsports.
