Published in 2017 at "Current Biology"

DOI: 10.1016/j.cub.2016.12.041

Abstract: Reduced exposure to daytime sunlight and increased exposure to electrical lighting at night leads to late circadian and sleep timing [1-3]. We have previously shown that exposure to a natural summer 14 hr 40 min:9 hr 20 min light-dark… read more here.

Published in 2025 at "Journal of Forensic Sciences"

DOI: 10.1111/1556-4029.70000

Abstract: Friction ridge patterns, including those from latent fingermarks, are valuable physical evidence in the identification of individuals in criminal and humanitarian investigations. Although latent fingermarks may persist over extended periods, their time‐dependent degradation remains poorly… read more here.
