Out @natcomms.nature.com:
our work on how the ❤️-supporting pericardium forms & acts in pediatric heart conditions.🎈🫀

Expanding our preprint & with our first HCR (thx to @thelovelylab.bsky.social!).

Congrats all! #devbio #zebrafish #CHD @cupediatrics.bsky.social @cudevbio.bsky.social

Very excited to see the first Beisaw lab publication out in its final form 🥳🥳 rdcu.be/ei1I7 if you’re interested in zebrafish heart regeneration and how cardiomyocytes replace the fibrotic injured tissue (spoiler alert: macrophages play an important role), then read it here 👇
Border-zone cardiomyocytes and macrophages regulate extracellular matrix remodeling to promote cardiomyocyte protrusion during cardiac regeneration
Nature Communications - Adult zebrafish are capable of heart regeneration, but how the collagenous injury site is replaced remains unclear. Here they provide an in-depth analysis of cardiomyocyte...

Know the difference.

The lab’s first pre-print! We investigated how growth-inducing Erk activity waves are regulated in regenerating zebrafish scales. We discovered that Erk waves are followed by waves of expression of their own inhibitors, as predicted by excitable waves theory. tinyurl.com/26r2cmpj

Our work out in @devbiol.bsky.social, PDGFra is needed for 🧠 perivascular fibroblast development... ⬇️ perivascular fibroblast = ⬇️ perivascular macrophage...cross-talk? 👀
Led by Hannah Jones @hejcell.bsky.social w/ Kelsey Abrams, Sophia Kim, excited for more projects w/ @fantauzzolab.bsky.social!
Micrscopy images of cleared cerebral brain tissue showing penetrating blood vessels (white) in mice - magenta cells are perivascular fibroblasts and cyan cells are perivascular macrophages - in control mice, both cell types are near the vessel termini by postnatal day 10 but in 'cKO' mice that lack expression of a tyrosine kinase receptor PDGFRa in fibroblasts, both the fibroblasts and macrophages are only partially covering the vessels.

This is such a cool study. A parasitic ant queen tricks worker ants into murdering their own queen, so the parasite can take over the colony.
This parasitic ant tricks workers into committing matricide
Newly mated parasitic queen ants invade colonies and spray their victims with a chemical irritant that provokes the workers to kill their mother.

On #NationalHomeMadeBreadDay, here’s the chemistry behind baking the perfect loaf: www.compoundchem.com/2016/01/13/b...

🧪 #ChemSky
Infographic titled “The chemistry of baking bread,” explaining how four main ingredients—flour, water, yeast, and salt—interact during the steps of mixing, kneading, fermenting, and baking. On the left is an image of sliced baguettes. Sections: Flour, water, and salt: Shows proteins glutenin and gliadin forming gluten when mixed with water. Notes that kneading strengthens the viscoelastic gluten network that traps gas. Explains flour’s protein content, how water hydrates proteins, and how salt adds flavor, slows fermentation, strengthens gluten, and improves elasticity. Starch and sugar: Illustrates starch as long chains of sugar molecules. Enzymes in flour convert starch to maltose, and yeast converts sugars like glucose for fermentation. Explains that sugar contributes to browning and flavor. Yeast and fermentation: Shows yeast converting glucose into carbon dioxide (which makes dough rise) and ethanol (which evaporates during baking). Describes yeast as single-celled fungi producing gas bubbles that expand the dough; kneading distributes bubbles. Includes sourdough information showing a 100:1 ratio of bacteria to yeast and the role of lactic acid in flavor. Other ingredients: Includes fats (which tenderize dough and stabilize gas bubbles), baking soda (sodium bicarbonate), baking powder (sodium bicarbonate plus cream of tartar), ascorbic acid (strengthens gluten), and xanthan gum (used in gluten-free breads).
