Quantum Biology: Five Surprising Lab Clues

Weak radio waves disrupted migratory birds’ compass orientation, consistent with spin-sensitive pairs of reactive molecules, though the sensor remains unknown.

In soybean lipoxygenase, replacing hydrogen with heavier deuterium produced an 81-fold rate effect, interpreted as evidence of tunneling.

A heat-loving alcohol-dehydrogenase enzyme showed more hydrogen tunneling at 65°C than at or below room temperature.

Human and mouse smell receptors responded similarly to ordinary and isotope-labelled odorants, challenging the quantum vibration theory of smell.
