Embryogenesis in Myrmicine Ants Combines Features of Short Germ‐Band Development With a Progressive Mode of Segmentation

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Different insect species exhibit remarkable diversity in the developmental trajectories from fertilized eggs to hatching larvae. For three myrmicine ant species, we observe a novel combination of a developmental features: small embryonic primordia, a mode of embryogenesis termed short/intermediate germ‐band development, and progressive establishment of

Incidence of biliary atresia in the United States before and during the COVID‐19 pandemic

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives The etiology of biliary atresia (BA) is unclear and potentially involves viral triggers. We aimed to compare the incidence of BA in the United States before and during the coronavirus disease 2019 (COVID‐19) pandemic, focusing on potential associations with viral circulation disruptions caused by nonpharmaceutical interventions ...

Increasing acidification does not affect sexual reproduction of a solitary zooxanthellate coral transplanted at a carbon dioxide vent

open access: yesLimnology and Oceanography, EarlyView.
Abstract The absorption of atmospheric carbon dioxide is causing significant changes to the carbonate chemistry of the ocean, in a phenomenon called ocean acidification. The latter makes it potentially more difficult for marine calcifiers like corals, to build their calcium carbonate structures, thus affecting their ability to survive and reproduce ...

AI-powered simulation-based inference of a genuinely spatial-stochastic model of early mouse embryogenesis [PDF]

open access: yesarXiv
Understanding how multicellular organisms reliably orchestrate cell-fate decisions is a central challenge in developmental biology. This is particularly intriguing in early mammalian development, where early cell-lineage differentiation arises from processes that initially appear cell-autonomous but later materialize reliably at the tissue level.
