These images show live embryos of animals (jellyfish, crustacean, worm, sea urchin, sea squirt, beetle) and one of animals closest single-celled relatives. They were captured taking advantage of fluorescent proteins localised on the outer membrane of cells, allowing us to observe cell outlines. 1/9

Why are some males caring toward infants while others are neglectful or abusive? I'm so pleased to share work that my colleagues and I @princeton.edu have just published @nature.com (an explanatory thread to follow!) (1/8)

The highly heterozygous European amphioxus (Branchiostoma lanceolatum) at the edge of panmixia Amphioxus are small marine chordates that have broad ecological ranges, yet as adults form local settlements and exhibit limited mobility. Genomic surveys of two amphioxus species have suggested that they rank among the most genetically diverse metazoans. Here, we present the first accurate assessment of genomic diversity in the European amphioxus ( Branchiostoma lanceolatum ) and investigate the processes underlying this diversity. We leverage high-coverage whole-genome sequencing data from multiple individuals sampled at two geographically distant Atlantic and Mediterranean locations. Consistent with previous estimates in other amphioxus species, we measure exceptionally high genomic diversity, with an average heterozygosity of 2.73% in B. lanceolatum . Despite the large geographic separation between sampling sites, population differentiation is minimal, indicating extensive gene flow among distant adult settlements. Phylogenetic analyses combined with population genetic simulations confirm that this elevated genomic diversity is primarily driven by a large effective population size. Although adult amphioxus have limited mobility, our results indicate that long-distance larval dispersal mediated by ocean currents is sufficient to generate a near-panmictic population structure across their broad ecological range. ### Competing Interest Statement The authors have declared no competing interest.

What is it like to have one of the highest genomic diversities among metazoans?

Just a murderous fungus having taken over a wasp and compelled it to die in a place advantageous to finding more victims. With its tiny spores floating off through the air in hopes of just one landing on an exoskeleton.. nothing in the rainforest wants anything to do with this little scene here…

50 years ago, King & Wilson published a foundational paper that underlies the cis-regulatory paradigm (CRP) of #DevoEvo #EvoDevo, i.e., that *almost* all morphological evolution is driven by mutations in regulatory elements, rather than proteins, and it all arose from simple misunderstanding 🧪 🧵

Hunger influences the behaviour of female mice towards pups Researchers find that virgin female mice can become aggressive towards pups when hungry, but only in certain hormonal states.

Researchers at the Crick found that virgin female mice can become aggressive towards pups when hungry, but only in certain hormonal states.

It highlights the importance of understanding hormones when observing how different physical states interact in the brain.

#preprint:

We optimised the preparation of tissues for #X-ray phase contrast imaging.

Drying tissue samples (instead of embedding them) brings more signal in #X-ray phase contrast images.

The process largely preserves #ultrastructure.
