Human age reversal: Fact or fiction?
Johnson AA, English BW, Shokhirev MN, Sinclair DA, Cuellar TL. Johnson AA, et al. Aging Cell. 2022 Aug;21(8):e13664. doi: 10.1111/acel.13664. Epub 2022 Jul 2. Aging Cell. 2022. PMID: 35778957 Free PMC article. Review.
Estimates of biological age are thought to be provided by aging clocks, which are computational models (e.g., elastic net) that use a set of inputs (e.g., DNA methylation sites) to make a prediction. ...Although rigorous clinical trials are needed to validate these …

Generation of circadian rhythms in the suprachiasmatic nucleus.
Hastings MH, Maywood ES, Brancaccio M. Hastings MH, et al. Nat Rev Neurosci. 2018 Aug;19(8):453-469. doi: 10.1038/s41583-018-0026-z. Nat Rev Neurosci. 2018. PMID: 29934559 Review.
Technical and conceptual advances, including intersectional genetics, multidimensional imaging and network theory, are beginning to uncover the circuit-level mechanisms and emergent properties that make the SCN a uniquely precise and robust clock. However, much remains unk …

Epigenetic aging: Biological age prediction and informing a mechanistic theory of aging.
Li A, Koch Z, Ideker T. Li A, et al. J Intern Med. 2022 Nov;292(5):733-744. doi: 10.1111/joim.13533. Epub 2022 Jun 20. J Intern Med. 2022. PMID: 35726002 Review.
Numerous studies have shown that epigenetic age-an individual's degree of aging based on patterns of DNA methylation-can be computed and is associated with an array of factors including diet, lifestyle, genetics, and disease. ...Prediction of age was an important first ste …

Disruption of adolescents' circadian clock: The vicious circle of media use, exposure to light at night, sleep loss and risk behaviors.
Touitou Y, Touitou D, Reinberg A. Touitou Y, et al. J Physiol Paris. 2016 Nov;110(4 Pt B):467-479. doi: 10.1016/j.jphysparis.2017.05.001. Epub 2017 May 12. J Physiol Paris. 2016. PMID: 28487255 Review.
Although sleep is a key element in adolescent development, teens are spending increasing amounts of time online with health risks related to excessive use of electronic media (computers, smartphones, tablets, consoles) negatively associated with daytime functioning and sle …

The neural bases for timing of durations.
Tsao A, Yousefzadeh SA, Meck WH, Moser MB, Moser EI. Tsao A, et al. Nat Rev Neurosci. 2022 Nov;23(11):646-665. doi: 10.1038/s41583-022-00623-3. Epub 2022 Sep 12. Nat Rev Neurosci. 2022. PMID: 36097049 Review.
We propose that, from a biological perspective, these two forms of duration estimation are supported by computational processes that are both reliant on population state dynamics but are nevertheless distinct. Prospective timing is effectively carried out in a single step …

Clocks in algae.
Noordally ZB, Millar AJ. Noordally ZB, et al. Biochemistry. 2015 Jan 20;54(2):171-83. doi: 10.1021/bi501089x. Epub 2014 Dec 30. Biochemistry. 2015. PMID: 25379817 Review.
Early algal models have contributed much to our understanding of circadian clocks at physiological and biochemical levels. The genetic and molecular approaches that identified clock components in other taxa have not been as widely applied to algae. ...The relative s …

The Effects of Time-Restricted Eating versus Standard Dietary Advice on Weight, Metabolic Health and the Consumption of Processed Food: A Pragmatic Randomised Controlled Trial in Community-Based Adults.
Phillips NE, Mareschal J, Schwab N, Manoogian ENC, Borloz S, Ostinelli G, Gauthier-Jaques A, Umwali S, Gonzalez Rodriguez E, Aeberli D, Hans D, Panda S, Rodondi N, Naef F, Collet TH. Phillips NE, et al. Nutrients. 2021 Mar 23;13(3):1042. doi: 10.3390/nu13031042. Nutrients. 2021. PMID: 33807102 Free PMC article. Clinical Trial.
Our results show the potential of smartphone records to predict metabolic health and highlight that further research is needed to improve individual responses to TRE such as a shorter eating window or its actual clock time....

A local circadian clock for memory?
Lehr AB, McDonald RJ, Thorpe CM, Tetzlaff C, Deibel SH. Lehr AB, et al. Neurosci Biobehav Rev. 2021 Aug;127:946-957. doi: 10.1016/j.neubiorev.2020.11.032. Epub 2021 Jan 18. Neurosci Biobehav Rev. 2021. PMID: 33476672 Review.
However, recent data suggest there is a circadian clock involved in learning and memory, potentially housed in the hippocampus, which is capable of acting independently of the master clock. ...Here we propose a mechanism by which the hippocampal clock could l …

Drop-counting flow computer.
Burgar CG, Winter GJ, Shepherd AP. Burgar CG, et al. Am J Physiol. 1985 Feb;248(2 Pt 2):H286-90. doi: 10.1152/ajpheart.1985.248.2.H286. Am J Physiol. 1985. PMID: 3155920
Neither tape recorders nor disk drives are needed because the flow-computing program resides in a "game cartridge." Furthermore, the power supply of the computer powers the interface and display. The computer's real-time clock is utilized to tim …
