Joaquín delivering a mental award lecture.

Terrific rallying cry of an @socdevbio.bsky.social award lecture from @mads100tist.bsky.social at #icdb2025! Our work and community are important, #DevBio matters, and it’s up to us to tell everyone why. Don’t give the enshittifiers an inch!

Congratulations to Blanche Capel for being awarded the #2025SDB Edwin G. Conklin Medal!

As cephalopods, longfin inshore squid have three hearts: two to pump blood through the gills & a third to circulate oxygenated blood around the body. @gertjanveenstra.bsky.social shows how each heart forms from a shared embryonic origin, in close concert with the gills.

Why is it advised not to drink when pregnant? For one, Mingi Hong highlights how exposure to environmental factors, like alcohol, affects developmental processes & increases the risk of birth defects like holoprosencephaly.

Essential for heart development, the protein MEF2C regulates the activity of other genes. @benoitbruneau.bsky.social (@dev-journal.bsky.social Editor) applies the latest high-resolution tech to unpick how gene networks are disrupted in time and space when MEF2C is lost.

Neptune: a Roman god; a planet; and now a new technology developed by @anderssonlab.bsky.social to trace the differentiation of each cell within the developing mouse ectoderm – a tissue that gives rise to the skin, sensory organs (e.g. inner ear) & nervous system.

The ornamental Polish chicken, which has an extra-feathery crown, is Cheng-Ming Chuong's species of choice to study how skin has region-specific developmental programmes by comparing feather shape, colour & pattern variation in different anatomical locations.

Mechanisms of regeneration: to what extent do they recapitulate development? Summary: By comparing regeneration and development, this Review highlights new insights into morphogenesis, revealing potential non-developmental strategies for tissue regrowth.

You might not have heard of the three-banded panther worm, but it's Mansi Srivastava's animal of choice for understanding the extent to which embryonic development & regeneration share common mechanisms

Schwann cells wrap neuronal axons like the tortilla around a burrito. Sarah Petersen reveals that Schwann cells promote regeneration in response to injury and aims to unpick their enigmatic nerve-wrapping dynamics.

Lots to 🩷 about an axolotl but, for @jesslamae.bsky.social, the appeal of these smiley salamanders is trying to harness their ability to regenerate limbs. Prof. Whited highlights how the removal of one limb induces changes in cell behaviour throughout the whole body.

Zebrafish regenerate their hearts without scarring but, like humans, medaka fish cannot - unless their immune system is activated by simulating a viral infection. Ben Shih-Lei Lai 賴時磊 highlights that immune cell-dependent clearing of damage promotes heart regeneration.

Unable to move, plants tough out unfavourable environments by changing shape. Jorge Casal explains how, in shade, plants seek sunlight by growing taller. Then in light, the accumulation of light-activated protein 'condensates' halts vertical growth.

Attending #ICDB2025? I will present my work titled, "Saa2/Neat1 and Grem1 positive mesenchymal stem cells respond to intervertebral disc damage by upregulating tissue-specific differentiation
markers post injury" on Saturday (6/21) at 10:50-11:05am in the San Juan Ballroom 1-3. Stop by!

I am having a great time at my first SDB conference! If you are interested in PNS glia or SCP migration, please check out my poster this afternoon (B108, abstract 334)! #ICDB2025

Embryos initially rely on factors deposited in the egg to grow before generating materials via their own genome. Using flies, Shelby Blythe studies how chromatin-associated proteins (histones) are modified and how these modifcations relate to zygotic genome activation.

Sugar is usually thought of as a cellular fuel, but it also changes how cells differentiate. preLighter (@prelights.bsky.social) @martinestermann.bsky.social shows that metabolites, such as sugars, influence the development of sex organs—ovaries & testes. Sweet story!

Segmentation and patterning of the vertebrate hindbrain Summary: This Review discusses how sharp patterns of segments and boundaries are formed during hindbrain development.

Very fundamental processes, such as sleep and swallowing, are regulated by the hindbrain. Rob Krumlauf studies how the hindbrain develops through a segmentation process - with each segment having a distinct identity.

Externally, humans look symmetrical but our internal organs aren't. Focusing on a key asymmetric organ, the heart, @rburdine1.bsky.social studies how asymmetry arises during zebrafish development in a process called jogging, which occurs when heart progenitors migrate.

People say that mice love cheese, but how do they eat it? Jaws - and the ability to bite and chew - have only existed for about half the time that animals have been on the planet. @smarable.bsky.social studies how the jaw forms from precursors called neural crest cells.
