Estimating Polar Bear (Ursus maritimus) Age Based on an Epigenetic DNA Methylation Clock [PDF]

open access: yesEcology and Evolution
Knowledge of animal age is essential to wildlife managers for obtaining meaningful and accurate insights into demographic parameters. A common approach to aging wildlife, including bears (Ursus spp.), has been extracting a tooth during physical capture ...

The circadian clock influences T cell responses to vaccination by regulating dendritic cell antigen processing

open access: yesNature Communications, 2022
Circadian rhythms are known to impact a range of biological processes including in the immune system. Here the authors show how circadian rhythms modulate the T cell response to vaccination via regulation of dendritic cell metabolism.

Archaeological clocks in the mosques of Vuh are an artistic archaeological study in light of agroup published for the first time [PDF]

open access: yesJournal of Architecture, Art & Humanistic Science, 2022
The clock is a tool for knowing and measuring time، and the medieval Muslims، was in dire need to know the time and determine it، because the prayers imposed on them were linked to specific times of the day. Therefore، Muslim scholars at that time worked

Aging alters across-hemisphere cortical dynamics during binaural temporal processing

open access: yesFrontiers in Neuroscience, 2023
Differences in the timing and intensity of sounds arriving at the two ears provide fundamental binaural cues that help us localize and segregate sounds in the environment. Neural encoding of these cues is commonly represented asymmetrically in the cortex

The GH-IGF-1 Axis in Circadian Rhythm

open access: yesFrontiers in Molecular Neuroscience, 2021
Organisms have developed common behavioral and physiological adaptations to the influence of the day/night cycle. The CLOCK system forms an internal circadian rhythm in the suprachiasmatic nucleus (SCN) during light/dark input.

Accurate timekeeping is controlled by a cycling activator in Arabidopsis. [PDF]

open access: yes, 2013
Transcriptional feedback loops are key to circadian clock function in many organisms. Current models of the Arabidopsis circadian network consist of several coupled feedback loops composed almost exclusively of transcriptional repressors.
