Regulation of peripheral glucose levels during human sleep Abstract. Studies in rats indicate that oscillatory signatures of memory processing during sleep, specifically hippocampal sharp wave-ripples, also regulat

Super cool work published in the latest issue of @sleepjournals.bsky.social showing a novel connection between sleep architecture and peripheral glucose ⬇️ #SleepPeeps academic.oup.com/sleep/articl...

Let us please, once and for all, ban any and all headlines that begin "Do/eat this ONE THING to..." (lose weight, improve sleep, reverse aging, reach enlightenment)

I hate to break it to you, but there is no easy, miracle solution to any of it. Nothing exists in a vacuum.

Non-Image-Forming Effects of Daytime Electric Light Exposure in Humans: A Systematic Review and Meta-Analyses of Physiological, Cognitive, and Subjective Outcomes Light exerts numerous nonvisual or non-image-forming, effects – such as its impact on melatonin suppression, circadian phase-shifts, sleep quality, and alertness. While research typically focuses o...

On Monday, I participated in my first online co-working hour with a diverse group of kind people who are either scientists or science-adjacent, all just looking for community during these trying times. It was so lovely! Never underestimate the power of community.

I’ve read this a few times now and ugh, it’s so important. #SleepPeeps 👏

This is so exciting! Thanks for your dedication and leadership in this space @grandner.bsky.social and @m-pst-ongephd.bsky.social! Go check it out, folks 👇 #SleepHealth

Thank you for believing in me!!

Thanks for the feature @uazbio5.bsky.social! I hope that my weird and winding path to where I am now encourages others to never stop dreaming 🛌

British friend visiting me in the US & watching hotel room TV commercials: “so, if I understand correctly, they seem to go between ads for fast food and medications for the diseases caused by the fast food?”

Bright days and dark nights (although technically we’ve just had a full moon) up in this part of Arizona = a circadian paradise! #CircadianRhythms #GetOutside

And breathe 🌬️

Now this is what it's all about! 🙌 Thanks @uazbio5.bsky.social for doing a stellar job to bridge the gaps that exist between scientists, as well as those that exist between the public and science. Loved attending "Behind BIO5" to nerd out with anyone willing to listen! #SciComm

If you aren’t on this mailing list, I highly recommend it. Grateful for @lizneeley.bsky.social’s efforts!

This newsletter is such a gift to the people and I’m so grateful for it.

More reasonable start times are definitely gaining traction! It’s so cruel to have them on those awful schedules. It’s like an adult having to wake up at 2-3am every day!

It really is! We haven't had the usual wildflower bloom this month due to a REALLY dry winter, but I'm hoping the last week of good rain rejuvenates the plants!

Is there anything better than a Sunday stomp about the mountain? Endlessly grateful for this Sonoran sunshine ☀️

DeeeeLIGHTful to attend a session on “life’s rhythms” at this year’s #TucsonFestivalOfBooks. Shoutout to @lynnepeeps.bsky.social for mentioning dark skies, light justice, and school start times.

For World Sleep Day, @katkennedy.bsky.social, 2025 BIO5 Postdoc Fellow has perspective:

"Everyone's experience with sleep is different, but I believe how we sleep reflects how we spend our days. It's crucial to give ourselves space during the day to process stress, so we can sleep better at night."

When we sleep = when we eat = how we eat = how we live = how we eat = when we eat = how we sleep = how we feel

Everything is connected.

We need to stop forcing kiddos (who are already so vulnerable in today's crazy landscape) to wake up at the crack of dawn. Don't we want them to be set up for success? Don't we want them to thrive? Here's a review. #StartSchoolLater

Always a nice reminder of how hideous the clock change is when I somehow end up spending this weekend out of Arizona *runs outside to absorb the gloom*

As always, a sensational selection of posters on offer at @ahascience.bsky.social #EPILifestyle25 - here’s a fave 👌

Thanks!
