Takeya Kasukawa and Masahiro Sugimoto from the RIKEN Center for Developmental Biology have a better way. Their team have developed a “metabolite timetable” that plots how dozens of molecules rise and fall in relation to one another. With this timetable, they could accurately read a person’s internal clock with just two blood samples, taken 12 hours apart.
It was inspired by flowers.
