This issue is all about insects! We start with a review by a new investigator, Deniz Top, on the neural network of the Drosophila circadian system. Before you dig into the first original article using Nanda-Hamner curves to study Drosophila circadian and photoperiodic responses, refresh your knowledge with the tutorial on Nanda-Hamner protocols. Genetics underlying circadian period and links between circadian phase and masking are described in our next two articles. Experiments showing the necessity for a molecular clock for stable entrainment of Drosophila eclosion under naturalistic settings is described. Monarch butterflies are used in studies of constant light and resistance to parasites. Our final study wraps up this issue with a demonstration that individual barcoded ants do not show activity-rest rhythms.

Check out our August issue of JBR, SRBR’s very own journal. Our journal is receiving multiple excellent review articles from new investigators! We open this issue with a review by Jennifer Hurley on “Circadian Interactomics” that will bring you up to date on the macromolecular complexes of the core circadian clock in many model circadian organisms. You can then dive into articles on the molecular clock in Neurospora, effects of light on mouse ventilation, or ultradian rhythms in voles. We have an update on development of a biomarker for circadian phase in humans, as well as a report on impact of caffeine intake on REM sleep timing and an analysis of chronotype-specific sleep in shift-workers. Our issue wraps up with a letter describing experiments using heavy water to alter circadian period in mouse SCN.

1-Datablitzes: This activity is aimed at promoting the research of junior scientists in our community. Authors (preferably trainees) present their newly published research in chronobiology in the form of short videos that the POC will promote via social media. These videos can be in any format of the author's choosing, e.g., cartoon, graphs, pictures, slides, with or/without the author's face. Videos can be submitted via srbroutreach@gmail.com. If shared on the authors’ social media, please use the hashtag #ChronoBlitz. The target audience for this first edition of the Datablitz will be the general scientific community, and future initiatives will focus on the general public.

2-Chronotrivia: Our public outreach fellow has launched this new social media event and we encourage everyone to participate, using the hashtag #ChonoTrivia. The goal is to share interesting chronobiological facts to feature in our #TriviaTuesday. The first post can be found here:  https://twitter.com/SRBR_Outreach/status/1412033523041587202?s=20

Everyone interested in contributing to the POC activities or who would like to share announcements can contact us via srbroutreach@gmail.com
