Ten years since the discovery of the fabled Higgs boson, can the Large Hadron Collider ever make us that excited again? Physicists are now kind of bored by the Higgs - the hype has well and truly died down. So as the LHC kicks off its third period of operation, the team asks whether there will be anything new to get them fired up again. How do large hawks land without crashing?

The organisation has recently brought cases against the Dutch airline KLM and French oil giant Total Energies for alleged greenwashing. Rowan speaks with Chief Impact Officer and “head of greenwashing” Maria Krystyna Duval. A strange kind of time paradox called causal loops is being researched. As well as explaining what a causal loop is, the team explains how a large set of theoretical universes were studied to see whether this time-travel paradox could actually work.
