How can light, lifespan and reproduction be connected? The marine worm Platynereis dumerilii gives us surprising insights..

Full details in the fun & impressive paper from Andreatta et al doi.org/10.1073/pnas...

And plot twist.. Actually, spring is coming and the dragons do sleep..

#EESBioOsc
Thanks for hosting us
@events.embl.org

And it's a wrap for #EESBioOsc.. Today we heard about oscillations in cilia, scRNA, singing mice or reptiles among others
@micromotility.bsky.social @events.embl.org

Am 24.04. findet wieder die Lange Nacht der Forschung statt – auch bei uns an der Uni Wien in der Schlachthausgasse im 3. Bezirk.
Es gibt viel Spannendes auch für Kinder zu entdecken, auszuprobieren und
zu bestaunen.

Many other cool talks and discussions.. Including a nice walk in the woods to admire century-old sequoias.. The walk started with a few snowflakes and ended with the sun.. The trees heard about very diverse science as we walked by
@events.embl.org #EESBioOsc

Plus more fun science, connecting the physics of oscillatory dynamics to biology via e.g. hearth and defibrillation (Flavio Fenton) or voice production (Coen Elements) in so many different species going from birds to humans or whales..

Another cool day @events.embl.org for #EESBioOsc

Super great talks + poster on the lunar clock and behavior of our beloved worm P. dumerilii by @federicoscaramuzza.bsky.social and Aida Coric @tessmarraiblelabs.bsky.social

Six Lectures on the Fundamental Properties of Circadian Clocks

my former boss (and amazing mentor) Carl Johnson just released a series of lectures on the fundamental properties of #circadian clocks, which you should definitely check out if you're interested in chronobiology!

And cool lecture and workshop on how to model biological rhythms by Hanspeter Herzel and @martdelolmo.bsky.social
#EESBioOsc with hands-on scripts to test!

Very nice first day at #EESBioOsc Loved the diversity of talks, including rhythms in jazz, fly development, and modeling!

And thank you for the invitation, it is an honour and a pleasure to be here :)

Google Has a Secret Reference Desk. Here's How to Use It. 40 Google features to find exactly what you need, the alternative search engines that do things Google won't, and the reference desk framework underneath all of it.

This is a great list of techniques for getting real information out of a Google search and avoiding AI slop and paid results.

A cellular basis for the mammalian nocturnal-diurnal switch Early mammals were nocturnal while dinosaurs dominated the daytime. Mammalian transition to daytime activity accelerated after the Cretaceous-Paleogene extinction, but the underlying mechanisms remain...

Since I moved to @mrclmb.bsky.social I’ve been trying to answer this: Why are some mammals active at night and others in the day? Today our answer is out @science.org www.science.org/doi/10.1126/....

A light-entrained clock mechanism in a hydrozoan jellyfish synchronizes evening gamete release Jellyfish rely on light cues to help coordinate the timing of their gamete release. By characterizing a new species of jellyfish, this study reveals an additional autonomous circadian mechanism that s...

Congrats Nadja et al for this very great work and paper! Really cool story to check out :)

Thank you very much Tim @thechitoncorner.bsky.social for inviting me for this seminar. Very nice questions and discussion, it is always a pleasure and an honour to share our research!

Lumière sur les abysses YouTube video by Maison de la Mer

Pour les francophones et une vue des écosystèmes profonds en général, une conférence grand public que j ai donnée en 2021 à l invitation de la Maison de la Mer a Lorient #oceanprofond #deepsea (~50 min + questions)

Deep-sea mining plans should not be rushed Why are companies and governments determined to start commercial-scale mining for rare metals, when so little is known about its wider impacts?

So: the deep sea is one of our greatest ecological frontier. They belong to humanity. And #deepseamining could destroy it before we even know or understand it.. So let's be aware of the crucial fundamental stakes that are there. Let's not let them out of sight

Yet.. Oceans and the deep ocean are crucial for climate change, oxygen production, globally life on our planet.. We need them to breathe!

We have 7m x 7m maps of the entire moon, soon going down to 5m x 5m. This means than 1 pixel is a square of 7x7. Only 26% of the deep-seafloor has been mapped. The gap is expected to be filled by 2030, but for ~75% of it, the resolution will be 400 m x 400 m. So 80x less

And we are pretty ignorant of how it works: the biology, the biodiversity, the functioning,.. Probably just a few % of the species have been described

So these environment are very different from what we know, even "extreme" from a human perspective. However, the #deepsea is not "the deep sea" but a mosaic of ecosystems where life developed and even thrives, such as at hydrothermal vents. But those ecosystems are based on a different biology..

Temperature is cold (mean = 4°C), pressure very high. At sea surface, pressure is 1 bar. Every 10 m, one add another bar. So at 1000 m depth, the pressure is 100 bar, 100x more than the surface. For comparison: pressure at Mount Everest (8848 m) is 0.34 bar, just 3x less
#deepsea

#Deepocean = waters < 200-300 m depths, where sunlight is insufficient for net photosynthetic production to occur. Until 1000 m depth, it's the twilight zone, where some very very dim residual sunlight remains. Then, there is no sunlight at all. Hence, no alga

The #deepsea.. Laterally a very vast subject. 70% of our planet is covered by oceans.. Actually, we talk mostly about deep oceans, that cover 66% of Earth. In volume, they would represent ~93% of the biosphere.. And we are pretty ignorant of how they work..
