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.

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.

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."
