New paper from the Rosin lab in collaboration with the Hawley lab 🎉 Spearheaded by postdoc Leif Benner. We use imaging and RNA-seq to better understand apyrene meiosis.

Programmed meiotic errors facilitate dichotomous sperm production in the silkworm, Bombyx mori.

What a day it was! There are many past versions of me who did not believe that I could make it this far. Proud of myself for overcoming hurdle after hurdle after hurdle. Thank you to everyone who supported me on my way!

This #MicroscopyMonday shows the synaptonemal complex, which is a multi-protein structure that forms in early #meiosis between the maternal and paternal copy of each #chromosome. Here, we see two such structures in the fruit fly. @sillysciencelady.bsky.social (Hawley Lab & Gibson Lab)

My second PhD project is now out as a preprint! Our observations of the synaptonemal complex in wild-type Nematostella suggested an incredible degree of conservation. Then, our mutants told a story of dramatic functional divergence. We were bamboozled on a regular basis with this one! 🧪 #meiosis4eva

I’m so excited (and nervous!!) to be defending my PhD thesis on February 5th! If anyone is interested in virtually attending my thesis seminar, let me know and I’ll send you the zoom link. My seminar will focus on the Nematostella part of my thesis research. #meiosis4eva

Having been a PhD student of Scott’s is one of my greatest honors. I consider myself very lucky to have learned from him and that I found a research topic that I absolutely love, even on the most miserable days. 🧬

A bittersweet acceptance: Between a manuscript and grief

Stefanie Williams @sillysciencelady.bsky.social shares the story behind her paper on the synaptonemal complex, including a tribute to her supervisor Scott Hawley, who passed away while Stefanie was completing the research.

Are you an early-stage graduate student (2nd or 3rd year) or early-stage postdoc based in the US or Canada, working primarily in Drosophila? Would you like to help improve the experience of all trainees working in Drosophila research? If so, read on.

Just realized my comment didn’t really make sense because Scott also loved diet Coke, I guess my brain hadn’t started up yet when I initially replied 😂😂😂

Thank you! Oh, he absolutely would have! I would say I had one yesterday but I do prefer diet Coke to Coke anyways, so that’s nothing out of the ordinary for me either 😂

The synaptonemal complex component corolla regulates meiotic crossover formation in Drosophila melanogaster - Chromosoma In Drosophila melanogaster females, as in most organisms, the segregation of homologous chromosomes in meiosis depends on the formation of crossovers between them. In most cases, crossovers require th...

DO NOT MIX THESE CLEANING PRODUCTS
BLEACH + VINEGAR
Bleach and vinegar mixture produces chlorine gas, which can cause coughing, breathing
problems, burning and watery eyes.
BLEACH + AMMONIA
Bleach and ammonia produce a toxic gas called chloramine. It causes shortness of breath and chest pain.
BLEACH + RUBBING ALCOHOL
Bleach and rubbing alcohol makes chloroform, which is highly toxic.
HYDROGEN PEROXIDE +
VINEGAR
This combination makes peracetic/peroxyacetic acid, which can be highly corrosive

PSA for flood response: remember to NEVER mix cleaning solutions across classes, especially bleach x any ammonia or ammonium salts derivative (e.g. Lysol & many medical-grade spray cleaners)!! Biological hazard-graded respirators won’t protect against hazardous chemical fumes.

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers.

The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

Oh no I didn’t! Gotta check it out, thanks! Haha I take it I wasn’t able to provide any new names though which is sad. I’ll have to ask my wife, she has a lot more time for reading than me

Reposting this as the same issue continues at #IZFC2025: lots of red/green LUTs in talks.

Especially the #zebrafish crowd, with imaging as a key technique in our field, should be able to do better. And know how to.

Tamsyn Muir would be quite something different (unless you already read her books of course haha), I also really liked Malka Older’s “The mimicking of known successes” plus sequel
