What a cool way to get people engaged with #population #genomics!

But why is there no episode on parentage analysis ... ?

How to get the best night’s sleep: what the science says Chuck the gadgets, the fads and the alarm. Circadian research reveals how important your body’s internal clock is to blissful slumber.

"Chuck the gadgets, the fads and the alarm."

The importance of the #circadian #clock for human #sleep, covered in a recent News Feature in #Nature.

Our current follow-up #modelling study with @gokhalecs.bsky.social, former colleague @mpi-evolbio.bsky.social, suggests that larval competition for space can actually drive the evolution of divergent reproductive timing, aka #allochrony, which results in spatial separation and reduced competition.

Previous work with @kokkonut.bsky.social (tinyurl.com/28hxwree) showed that #sympatric Clunio strains reproduce AT full #moon or BEFORE new moon. During these times low tide levels differ, placing the eggs & larvae at different elevations. This spatial separation allows #coexistence of the strains:

How can larval #competition for space, adult #reproductive #timing and the #tides interact to produce different timing strains, aka #chronotypes, of the marine insect #Clunio?

Could humans and AI one day form a single β€œevolutionary individual”? Researchers at the Max Planck Institute for Evolutionary Biology raise this question in a new publication exploring human–AI interdependence.

Years of work distilled to 1 minute:
Our recent paper with @kokkonut.bsky.social has made it to #youtube !

The AI illustrations do not look anything like real-life #Clunio - but they are captivating.

And the scientific content is accurate and well explained!

In the second study we found out that differences in #lunar reproductive #timing of the adults can lead to spatial separation of the larvae, which in turn allows coexistence.
