📰 "Fruit flies actively restart their circadian clock by proactively shaping their environment"

bioRxiv · Fruit flies actively restart their circadian clock by proactively shaping their environmentCircadian clocks are prevalent on Earth and are generally believed to provide adaptive advantage to organisms. Functional circadian clocks, and their synchronization with the outside world, has also been implicated to provide health benefits for humans. However, experimental evidence for the benefits of possessing a circadian clock is sparse and largely restricted to prokaryotic organisms. Here, we provide evidence for the benefits of circadian clocks and temporally organized life in the fruit fly Drosophila melanogaster. We demonstrate that flies prefer and actively choose to live under circadian clock regulation: Exposure to constant light breaks down the circadian clock and leads to arrhythmic locomotor activity patterns. When given the choice to move between dark and illuminated areas in a constant light environment, flies were able to maintain, or even re-gain, rhythmic behavioural patterns. These rhythms were mirrored by regular positional changes between the two areas, demonstrating that flies actively contribute to creating an environment allowing circadian clock function and temporal organisation. The self-inflicted rhythms were accompanied by molecular rhythms in the majority of the clock neurons known to drive behavioural rhythms in flies, showing that they are indeed controlled by the circadian clock. Finally, behavioural rhythmicity was correlated with restoration of rhythmic sleep patterns and less-fragmented sleep compared to arrhythmic flies. While life is possible without a circadian clock, we show that if given the choice, animals prefer to live in a temporally organized manner and actively contribute to make this possible. This provides strong arguments for the benefits of possessing and using a circadian clock, for example by ensuring a better quality of sleep ### Competing Interest Statement The authors have declared no competing interest.

Researchers from the University of Surrey in the UK ran an experiment involving 36 volunteers aged 60 or over, testing their response to two-hour-long sessions of blue and regular white light twice a day over several weeks. They have discovered that a morning dose of blue light might help older people sleep better in the evening, giving them a boost for their daily activities the following day. @ScienceAlert reports:

Hey everyone. Check out this comic, I learned a lot of stuff about something I was totally unaware of:

m.tapas.io/episode/2260300

@hiisikoloart teaches us about "Idiopathic Hypersomnia". And even with this rather dark topic, some of the comics may make you laugh or feel other things.

(I hope you don’t mind… I’m trying something out where I cross-post our small business’s posts here.

If you’re still reading this… :) the backstory is I’ve revamped our content and email marketing efforts— oops, I lost you at the word "marketing”. Well the point is we realized as a business that our mission is to *help families get better rest* and physical products get you only so far in that effort. Our founder, my wife, has legit expertise in treating sleep issues, as a psychologist, so… anyway, here's why we're doing this:

And if you're a parent who could use better rest, I hope you’ll sign up for our newsletter. Feedback encouraged!

OolieBetter Sleep and a Peaceful HomeDear friend, I’ve had an epiphany. Parenting can be magical and infinitely rewarding, yet it’s also the hardest job you’ll ever have — and it’s 24/7, every day, for the rest of your life. You never stop being a parent. For such a demanding job, getting the rest you need (and deserve) makes it easier. Better rested parents are more available and more present with their kids and partners. Better rested families are healthier, happier, more connected, and more resilient. I have a vision in which every family gets better rest and lives together more peacefully. Because with more rest, parents and kids are happier, families are more calm and secure, and we can model, build, and sustain healthy relationships in which everyone gets their needs met. — That’s why I started Oolie: to help families get better sleep. But my epiphany was that even the most well-designed and constructed organic bedding and baby products aren’t enough to get us there. The keys to better sleep are in how we live each day. As a clinical psychologist, I’ve specialized in treating insomnia and other sleep challenges. I am familiar with the latest research on sleep and how to cultivate the conditions for a successful night’s rest. As a parent to three young children, I’ve learned how to get myself and my kids a good night’s sleep. (Okay, maybe not every night, but most nights!) I’m going to start sharing more of what I’ve learned with you, through this email newsletter and blog. Look for a new post from me every Sunday morning. You can expect: personal stories about what’s helped me and my kids insights about the science of sleep baby steps to get you better sleep Thanks for being here. Sleep well,Nora
