Four years have passed since the death of Queen Elizabeth II: the queen who drove trucks, created a dog breed, and left a letter for 2085.

Today marks four years since the death of Queen Elizabeth II, who passed away at the age of 96 on September 8, 2022, at Balmoral Castle in Scotland. Her passing concluded a historic 70-year reign, the longest in British history. Buckingham Palace officially confirmed the monarch's death four years ago today, closing an era defined by her long tenure and notable personal history.

Coverage of the anniversary highlights several lesser-known aspects of the late queen's life and legacy, including her wartime service driving trucks, her role in creating a new dog breed, and a mysterious letter she left behind to be opened in the year 2085. Concurrently, separate scientific developments in Peru, involving researchers from the Pontificia Universidad Católica del Perú and the Instituto Nacional de Oftalmología, are working on early detection technologies for eye disorders.
