What if biology is missing part of the picture?
Quantum biology asks whether some processes in living systems depend on quantum effects, the same physics that governs electrons and atoms.
For a long time, this seemed unlikely. Quantum effects are notoriously delicate, while living systems are warm, wet, and constantly in motion.
And yet, biology keeps giving us reasons to look more closely.
Studies have found that weak magnetic fields can influence processes including oxidative stress, DNA repair, ion channels, and cell growth.
One possible mechanism is the radical pair mechanism, where the quantum behavior of electrons can alter the course of a chemical reaction.
That could matter because electron chemistry sits behind many processes essential to life, from energy production and metabolism to cellular signaling.
We still have a great deal to understand. But if quantum effects really do play a meaningful role in these systems, they may give us a new way of looking at health, disease, and life itself.
