In 2019, scientists at Yale University harvested the brains of pigs that had been decapitated in a commercial slaughterhouse four hours earlier. Then they perfused the brains for six hours with a special cocktail of drugs and synthetic blood. Astoundingly, some of the cells in the brains began to show metabolic activity again, and some of the synapses even began firing. The pigs’ brain scans didn’t show the widespread electrical activity that we typically associate with sentience or consciousness. But the fact that there was any activity at all suggests the frontiers of life may one day extend much, much farther into the realms of death than most scientists currently imagine.

The long read: New research into the dying brain suggests the line between life and death may be less distinct than previously thought
