A Conservative Defense: Downstream NFLs Resist Evolutionary Blitzes
By Andy Flick, Evolutionary Studies scientific coordinator In football, defense keeps the opposing team in check. A similar strategy is at play inside our cells. Negative feedback loops (NFLs) help regulate how cells respond to signals, for example, dialing down activity when things get too intense. A new study from… Read MoreMay 9, 2025
