@tricytomeet.bsky.social continued with a lively poster session. I particularly liked the presentation by Naveen Chana, about work in Sid Shaw's IU lab on the plant augmin complex & microtubule regulation. She's now a PhD student in Joe Kieber's lab at UNC

Happy #FluorescenceFriday !🌈

Today, sperm cells & developing gametes (Dapi, 🟢🟡🟠🔴) and testis muscles (Phalloidin (🔵🟢) in/on a #Drosophila non-melanogaster (guess the species and you’re the 🐐)

Happy Pride! The diversity of life, in all its forms, is pretty rad!

(Side note: there's not a whole lot of purple fish, so the pink/silver goldeye is the best I got)

#SundayFishSketch #Pride
Six fish arrayed diagonally over the top of a rainbow pride flag. At the top left on the red stripe is a northern redbelly dace (Chrosomus eos), on orange is a male rainbow darter (Etheostoma caeruleum), a shorthead redhorse (Moxostoma macrolepidotum) on the yellow stripe, a northern pike (Esox lucius) for the green stripe, an orangespotted sunfish (Lepomis humilus) on the blue strip and a goldeye (Hiodon alosoides) on the purple stripe.

I've been camping almost every weekend as of late so haven't been able to post #SundayFishSketch, but here is an edited version of my Rainbow Trout illustration with altered coloring in honor of #PrideMonth.
An illustration of a Rainbow Trout, but instead of the realistic coloring on the body, the colors make a rainbow in honor of Pride month.

Hi #FluorescenceFriday community! 🌈
Fly testes are unexpectedly stunning 😀

Here’s a testis from a non-melanogaster Drosophila species:

🔵🟢 Muscles: Phalloidin

My single favourite wildlife photo from our trip to Galápagos has to be this marine iguana sneezing out salt - such an elegant and glamorous adaptation to their unusual lifestyle!

2/4 I chose this picture because I am interested in an old question:

How do fly testes obtain their specific shape?

In my previous research I learned that muscle precursors shape it, using collective cell migration and alignement to achieve the pattern visible in this picture.

“What’s the deal with GARS?”

Here’s a #GarWeek mega-thread of gar stories (aka GARticles) over the years:

Visited Chicago just in time for #Garweek and #fishmas! Saw live Shortnose & Longnose gar at Shedd Aquarium, then fossils at the Field Museum. The living gar's DNA is very similar to their ancient relatives!

@emily-mcparland.bsky.social, @noahgurley.bsky.social, Kevin Slep, @peiferlabunc.bsky.social and colleagues dissect the differential roles of the dual Ras-association domains of Drosophila Canoe in linking cell junctions to the cytoskeleton.
journals.biologists.com/jcs/article/...
Immunofluorescence images of embryos showing that CnoRA1 domain is important for dorsal closure, head involution and epidermal integrity. Wild-type (WT) embryo. Some cells are rounded up to divide (white arrows), but they rapidly return to columnar architecture. (B) cnoΔRA1. Groups of cells near the ventral midline fail to resume columnar architecture (red arrows). (C–E) Stage 11. (C) Wild-type embryo. (D,E) cnoΔRA1. Failure to resume columnar architecture becomes more apparent (red arrows). (F–H) Stage 14. (F) Ventral view of a wild-type embryo. Dorsal closure is completed (white arrow), head involution is underway (yellow arrow) and segmental grooves are shallow (green arrowheads). (G) cnoΔRA1. Dorsal closure failed, exposing underlying tissues (red arrow). There are gaps in the head epidermis (yellow arrows) and deep segmental grooves remain (green arrowheads). (H) Ventral view, cnoΔRA1. Holes in the epidermis (red arrows) and deep segmental grooves (green arrowheads) are observed. (I–J) Closeups, wild-type stage 10 (I–I″) and 11 (J). Dividing cells (green arrows) and forming tracheal pits (cyan arrows) are observed. Arm, Baz and Cno remain enriched at AJs. (K–K‴) Stage 10/11 cnoΔRA1 mutant. Cells that retained columnar architecture retain junctional Arm, Baz and CnoΔRA1 (yellow arrows). However, in some cells AJs are fragmented (red arrows) and in less epithelial regions Arm, Baz and Cno are strongly reduced (cyan arrows).

A renewed reminder to anyone applying for a PhD or postdoc position in a lab--indicate your interest in the email/cover letter by talking a bit about that lab's work and why it would be a good fit. I answer any query that includes this information but do not answer those that do not.

While our bodies seem static, our cells are constantly changing shape or on the move during tissue homeostasis or wound repair & even more dramatically during embryonic development, during events like gastrulation. Defining how cellular machines mediate these events is a key task for our field 1/n
