Pretty much every animal needs to be able to regulate its cellular processes around the 24 hour cycle of day and night, but unpicking how exactly cells manage to keep track of time has puzzled researchers until relatively recently. Then there’s the mystery of how cells’ molecular machinery keeps going at a constant rate, in spite of changes in temperature…
