Domesday Book: Not Just Taxes, But 11th-Century Big Data?

2025-07-10

New research challenges long-held assumptions about William the Conqueror's Domesday Book. Using the earliest surviving manuscript, Exon Domesday, researchers argue the survey wasn't simply about maximizing taxes, but a sophisticated exercise in governmental control—an 11th-century form of big data. The study reveals how William's administration gathered vast economic and territorial data across England in under seven months, processing it with astonishing speed and clarity. The team also proposes a likely identity for the principal scribe, potentially Gerard, William's chancellor. This innovative approach, using only pen, parchment, and human interaction, highlights the ingenuity of the Domesday creators and its significance as a remarkable feat of administrative innovation.

Environment trumps genes in aging and mortality: A UK Biobank study

2025-02-20

A study published in Nature Medicine used data from nearly half a million UK Biobank participants to investigate the impact of 164 environmental factors and genetic risk scores for 22 major diseases on aging, age-related diseases, and premature death. The research revealed that environmental factors explained 17% of the variation in death risk, compared to less than 2% explained by genetic predisposition. Smoking, socioeconomic status, physical activity, and living conditions were found to have the most significant impact. Early life exposures, such as body weight at age 10 and maternal smoking, also influenced aging and premature death risk decades later. The findings highlight the potential benefits of interventions focused on improving socioeconomic conditions, reducing smoking, and promoting physical activity.
