Check our latest pre-print where I’m a second author. We gathered evidence on the brain and nerve cord being specified autonomously by isolating blastomeres in two different annelid species. Great collaboration with @nicolewebster.bsky.social, @allancarbal.bsky.social and @biyolokum.bsky.social.

Weeeee! I’ve only ever seen one of these once before. This is the larva of an animal from the phylum Phoronida, which are kind of wormy, but feed using a lophophore, like a bryozoan.

At last, the dicyemid life cycle for #InverteFest! These absolute weirdos infect ONLY cephalopod kidneys; they are worms of discerning taste. 🦑🌊🐙🧪🐡
A detailed comic panel illustrating the life cycle of dicyemid parasites. Top text: "Despite their simple bodies of just a few cells, dicyemids have incredibly complex life cycles." Below that, a long brownish worm labeled "rhombogen" and a short brownish blob labeled "vermiform" are connected by arrows. The arrow leading from the rhombogen to the vermiform is "1. Adults make babies asexually" and the arrow leading from the vermiform to the rhombogen is "2. which grow into more adults." A separate arrow leads from the vermiform to a different brownish worm shape labeled "nematogen" and this arrow is "3. Sometimes they grow into different adults." An arrow from the nematogen to eggs and sperm is "4. which make babies sexually." An arrow leads from the eggs and sperm to the absolute cutest part of the life cycle, a round blob that looks like it has huge headlight eyes, though they are not actually eyes. The blob is labeled "infusoriform." An arrow leading from the infusoriform to an octopus is, "5. These different babies go infect new hosts!" I'M SORRY IT'S NOT MY FAULT THAT PARASITE LIFE CYCLES ARE SO STINKING COMPLICATED OKAY

Pleased to share our latest paper led by @tomlewin.bsky.social, now out in @currentbiology.bsky.social! We present the first chromosome-level genome of a phoronid and show that shared chromosomal fusions unite phoronids and bryozoans as sister groups.

This resource was vital for my college training as a biologist and I still use it even as an embryologist. So sad to see it end but wishing a smooth transition. I hope we can all see and appreciate the value of taxonomy databases in -truly- understanding natural history.

The Society for Developmental Biology has released a statement on the Unprecedented Disruptions to Biomedical Research in the United States.
Scientific research is a driving force behind human progress. It fuels medical breakthroughs, spurs technological innovations and drives economic growth. Federal funding of research by the National Institutes of Health (NIH) and the National Science Foundation (NSF) is absolutely critical for ensuring that the U.S. maintains its global leadership in science and technology. The unprecedented freeze on the review and issuance of federal research grants is already negatively impacting research and could have significant ripple effects. Ongoing studies may lose momentum if grant renewals or supplement requests are delayed, slowing scientific progress on research the NIH has already invested in. Researchers affiliated with the Society for Developmental Biology carry out critical research on birth defects, which kill twice as many children as cancer does. Slowed progress will delay the development of new therapies and diagnostics, and thus have real public health implications. In 2019, the total estimated cost of birth defect–associated hospitalizations was $22.2 billion. Scientific research is also critical to the U.S. economy more broadly. In 2023 alone NIH funded research not only directly supported 412 thousand jobs, but its overall economic impact rippled out to all sectors of the economy driving more than $92.89 billion in economic activity across all 50 U.S. states and the District of Columbia. It is estimated that every dollar of NIH funding generates $2.46 dollars of economic activity. Finally, federal research funding not only drives impactful research discoveries but also supports the training of the scientists, engineers, and innovators of the future. University laboratories, funded by federal grants, serve as essential training grounds for the next generation of researchers even as they push the boundaries of knowledge. This training prepares young scientists for leadership roles in both academia and industry, helping to ensure that the scientific workforce r…
