Carotenoids, pigments found in fruits and vegetables, accumulate in human tissues after consumption. While cross-sectional studies have linked skin carotenoids to carotenoid intake, longitudinal data in childhood is limited. This study aimed to (1) describe changes in skin carotenoids and carotenoid intake in toddlers across 12 mo, and (2) examine cross-sectional relations between intake of carotenoids and skin carotenoids at each timepoint.

One of the remaining issues regarding the Anthropocene is the lack of stratigraphic evidence indicating when the cumulative human pressure from the early Holocene began to fundamentally change the Earth system. Herein, we compile anthropogenic fingerprints from various high-precision-dated proxy records for 137 global sites to determine the age of the unprecedented surge in these records over the last 7700 y. The cumulative number of fingerprints revealed an unprecedented surge in diverse anthropogenic fingerprints starting in 1952 ± 3 CE, corresponding to the onset of the Great Acceleration.

One important subset of these is thermoset composites with carbon reinforcement. The incorporation of carbon fillers and fibers gives polymeric materials improved electrical and mechanical properties, among other benefits.

We have, however, been able to reconstruct the deposition record of atmospheric H and Cl following the accident using a bore hole that was drilled in 2014 at Koriyama at a distance of 60 km from the accident. The contributions of H and Cl from the accident are 1.
