A short excerpt from Dr Russell Barkley's 2012 Burnett Lecture on ADHD, focused on treatment. He argues ADHD is a disorder of executive function and self-regulation, and that environments should be designed to compensate.

Russian-American journalist Vladimir Pozner lectures at Yale on how US foreign policy toward Russia after the Soviet collapse shaped Putin, then takes audience questions on election interference, the Skripal poisoning and media independence.

Stanford physicist Leonard Susskind explains what the Higgs mechanism is and what it means to give mass to particles. He also covers what is at stake for physics and cosmology.
