#Circadianclock as #pacemaker of #life: A single clock #signal initiates #geneswitching within a #cell. This #rhythmic process regulates the #activation/#deactivation of "morning"/"evening" genes. M. Fang et al. (2026) reproduced the #circadiansystem of #Synechococcus #elongatus (#Cyanobacteriota) within a test tube.They show that the overall #complexity of a cell is controlled by this genetic activity, which might find applications in #biotechnology.

Urban #lightPollution alters nighttime hormones in sharks, study shows
First-ever measurements of #melatonin in wild sharks show that artificial light from coastal #cities can disrupt nighttime #hormone levels, with resident species more affected than highly mobile #sharks.

A remarkable study has revealed that some of the world’s oldest plants don’t rely on colour or scent…

The time around the #wintersolstice, a symbolic period related to religious #traditions, #newyear celebrations, but also as a timer for #biological processes.
The decreasing amount of daily sunlight affects the biology of animals, e.g. in Form of the #circadianclock, an internal clock that is controlled by timers such as temperature and #light.

New research shows the complexity of #bacterial circadian clocks

The #CircadianClock of the #bacterium B. subtilis evokes properties of complex, #multicellular circadian systems https://www.science.org/doi/10.1126/sciadv.adh1308 by Francesca Sartor et al.

"The circadian clock in this #microbe is pervasive: we see it regulating several #genes, and a range of different behaviors."

“Experiments showed that the gene, Period 1, which is known to be involved in the body's circadian clock, is crucial for improved daytime memory performance.” #isogg #dna #epigenetics #circadianclock #memory #geneadons #GeneticGenealogy

Research has discovered a cold “coping” mechanism that is under the control of the plant biological clock and could offer solutions to breeding more resilience into crops less suited to cold climates. https://www.eurekalert.org/news-releases/984560 #science #plants #LifeOnTheEdge #ExtremeConditions #cold #CircadianClock

Sunflowers belong to one of the most successful plant families on Earth, perhaps thanks to their composite flower made of many mini florets.

Stacey Harmer explains how these florets stay in sync and why it’s so important. Listen to the #eLifePodcast 🎧 https://elifesciences.org/podcast/episode85?utm_source=mastodon&utm_medium=social&utm_campaign=organic #PlantBiology #CircadianClock

Extremely pleased that we put Nightscape issue 110 to bed and off to the printer, arriving soon to the inboxes (+US mailboxes) of International Dark-Sky Association members. Stories on the night/day cycle, night-sky poetry & more. Still time to join ($35/yr) and get your copy! https://darksky.salsalabs.org/NewMemberAnnual/index.html
