This episode of Physics World Weekly kicks off with James Dacey recounting his recent trip to the Netherlands, where he made a series of videos about energy-related research. You will hear David Smeulders of Eindhoven University of Technology argue that we need to rethink our current approach to energy storage and Dacey also describes his visit to a wind tunnel where cycling teams try to gain advantage by improving the aerodynamics of a bicycle and its rider.
Next up is Michael Banks, who explains why CERN is going to spend $1.5 billion to increase the number of proton-proton collisions at the Large Hadron Collider in Geneva. Tune in to learn how crab cavities could give us a glimpse of supersymmetry.
Tami Freeman then talks about radiation beams of a different sort – those used to treat cancer. She explains how a simple and inexpensive invention could provide intensity-modulated radiotherapy to millions of people in low- and middle-income countries, where financial constraints currently restrict access to this life-saving procedure.
