In 2008, archaeologists lifting a skull from a wet pit in York found something soft inside, and the Heslington brain preserved a life from Iron Age Britain

In a remarkable archaeological breakthrough in York, England, researchers unearthed ancient brain tissue that has astonishingly remained intact for over 2,600 years. This tissue, belonging to a man who likely met a violent end during the Iron Age, has proteins that formed resilient structures, effectively thwarting deterioration.
