During #embryogenesis, anterior-posterior axis formation depends on #chromatin accessibility, but axis determinants are species-specific. This study reveals complex temporal patterns of chromatin accessibility during axis specification in the moth fly.

The development of #salps differs from that of #ascidians in the presence of maternal cells called calymmocytes. This study of #embryogenesis in 2 salp species identifies distinct cleavage patterns & blastomere positioning, informing the study of their #evolution @PLOSBiology https://plos.io/4bscc6j

Ah, another groundbreaking discovery: #paracetamol might deviously meddle with #embryogenesis. 🤯 But hold on, you’ll need #JavaScript and #cookies enabled to access this revelation — because nothing screams cutting-edge #science like browser settings. 🍪🔍

The calcium surge that starts #embryogenesis varies across species. This Primer explores a @PLOSBiology study of #zebrafish, revealing that protease-activated receptors mediate a calcium signal that initiates #egg activation before #sperm entry.

What does #BetaCatenin do during early #embryogenesis? @evoinside_lab uses an inducible KD system to determine the spatiotemporal roles played by nuclear b-catenin in the early #SeaUrchin embryo @biodev_vlfr #PLOSBiology https://plos.io/48PgcML

How does BBM-mediated #parthenogenesis work? Understanding this process will help #PlantScience improve haploid #breeding efficiency. A new study by Liu et al. gets us one step closer. https://doi.org/10.1111/jipb.13678

here's a new science #rant on #aging :)

as far as biology can tell, aging is best understood, #philosophically at least, as part of a #developmental continuum between #embryogenesis & death, which is pre-programmed somehow. therefore, we cannot in principle place precise "boundaries" or "cutoffs" between development, adulthood, and seniority. In strict #biological terms, they are all part of one continuous #program. a complete explanation of aging therefore requires complete #devbio knowledge

Super cool article from @arstechnica! Among scientific advancements, artificial womb development is among the just exciting to me, particularly when the apparatus is amenable to instrumentation and measurement of the developing embryo.

Heat shock during #Drosophila #embryogenesis results in maternal miRNA retention & downregulation of pre-MBT genes including Elba1, which may contribute to setting the stage for subsequent gene expression ➡️ https://www.embopress.org/doi/full/10.15252/msb.202211148
