These vital dynamics occur across many scales of space and time, but the most fundamental is molecular: atoms and the bonds between them. The genetic code is written in atoms. It in turn specifies the atomic structures of proteins, biology’s energy and information processing units, which execute their functions in molecular space. Therefore, in a deep sense, atomic motion is the foundation from which life emerges. I seek to understand that motion.<br>\r\n<br>\r\nOne direct and powerful route is to film macromolecules with chemical resolution in both space (Å) and time (fs). I will describe a technology that uniquely enables us to achieve both simultaneously – the X-ray free-electron laser – and show how my team has used XFELs to watch two proteins at work.<br>\r\n<br>\r\nFirst, I will present our experiments on photolyase, an enzyme that harnesses light to repair life-threatening DNA damage. We found photolyase achieves very high repair quantum efficiency through an unexpected mechanism: by locking its photoexcited chromophore into a bent configuration. Further, photolyase achieves product/substrate specificity geometrically, using a rigid active site that matches substrate but not product. Second, I will share preliminary results on cryptochrome 4, a descendant of photolyase that has been proposed to act as an avian magnetosensor. Do birds navigate using a quantum magnetic compass? Our experimental program is investigating this provocative hypothesis.<br>\r\n </p>", "image_description": "", "creation_date": "2026-06-03T15:46:44", "last_modification_date": "2026-06-03T15:47:09", "link_label": "", "link_url": "", "canceled": "False", "cancel_reason": "", "place_and_room": "CH G1 495", "url_place_and_room": "https://plan.epfl.ch/?room==CH%20G1%20495", "url_online_room": "https://epfl.zoom.us/j/69070083096?pwd=vnb5szZbCwrgwapyo5Rz7k66ymnBA9.1", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "T.J.
