From extending lifespan to bolstering the immune system, the drug’s effects are only just beginning to be understood.
Newly designed sensors detect the magnetic fields generated by electrical activity within cat brains.

Light shone into one eye of an anesthetized cat stimulates electrical activity in the visual cortex. A magnetrode (green) inserted less than a millimeter into the visual cortex detects the magnetic fields created by this electrical activity. Insertion of an electrode adjacent to the magnetrode allows researchers to gather and compare electrical current and magnetic field data at the same time.
