Nighttime Light Hurts Mammalian Physiology: What Diurnal Rodent Models Are Telling Us

May 1, 2021
Mendoza, J. Nighttime Light Hurts Mammalian Physiology: What Diurnal Rodent Models Are Telling Us. Clocks & Sleep 2021, 3, 236-250. https://doi.org/10.3390/clockssleep3020014 Abstract Natural sunlight permits organisms to synchronize their physiology to the external world. However, in current times, natural sunlight has been replaced by artificial light in both day and nighttime. While in the daytime, indoor artificial light...

Children’s Health in the Digital Age

April 26, 2021
Dresp-Langley B. Children’s Health in the Digital Age. International Journal of Environmental Research and Public Health. 2020; 17(9):3240. https://doi.org/10.3390/ijerph17093240 Abstract Environmental studies, metabolic research, and state of the art research in neurobiology point towards the reduced amount of natural day and sunlight exposure of the developing child, as a consequence of increasingly long hours spent indoors...

Children who spent a lot of time in daylight were calmer

April 23, 2021
Source: https://sciencenorway.no/children-childrens-health-kindergarten/children-who-spent-a-lot-of-time-in-daylight-were-calmer/1847926 Kindergarten children were equipped with bracelets that measure light exposure. A study found a link between lots of daylight and low hyperactivity in the children. Anne Lise Stranden Wednesday 21. april 2021 Children who spent a lot of time outdoors during the day displayed fewer symptoms of hyperactivity. A new study of kindergarten children...

Circadian Misalignment and Metabolic Disorders: A Story of Twisted Clocks

April 5, 2021
Woller, A.; Gonze, D. Circadian Misalignment and Metabolic Disorders: A Story of Twisted Clocks. Biology 2021, 10, 207. https://doi.org/10.3390/biology10030207AMA Style Simple Summary In mammals, many physiological processes follow a 24 h rhythmic pattern. These rhythms are governed by a complex network of circadian clocks, which perceives external time cues (notably light and nutrients) and adjusts the timing of...

The circadian clock and metabolic homeostasis: entangled networks

March 15, 2021
de Assis, L.V.M., Oster, H. The circadian clock and metabolic homeostasis: entangled networks. Cell. Mol. Life Sci. (2021). https://doi.org/10.1007/s00018-021-03800-2 Abstract The circadian clock exerts an important role in systemic homeostasis as it acts a keeper of time for the organism. The synchrony between the daily challenges imposed by the environment needs to be aligned with biological processes...

Mitochondrial solar sensitivity: evolutionary and biomedical implications

March 6, 2021
Sommer AP. Mitochondrial solar sensitivity: evolutionary and biomedical implications. Ann Transl Med. 2020 Mar;8(5):161. doi: 10.21037/atm.2019.11.100. PMID: 32310246; PMCID: PMC7154450. Depending on cellular demand or oxidative stress, mitochondria produce adenosine triphosphate (ATP) or reactive oxygen species (ROS), thereby controlling the entire scale of cellular energy supply or disease, respectively. While deficiency in ROS can compromise...
