The IMPRS-BAC is an outstanding PhD program in Europe. And the endogenous retroviruses in development... what can I say? So much exciting biology to uncover! 🦠🧬#TEsky #StemCells

CoccidiaUK 2025 A biannual gathering of parasitologists from across the UK to discuss all things coccidian!

There's still time to register for CoccidiaUK in London - it's going to be a jam-packed two days of talks by early-career parasitologists, a knowledge transfer session, plus trivia and prizes! It's @crick.ac.uk (very central) & we're cooking up some fun swag :) www.eventbrite.co.uk/e/coccidiauk...

There will be talks, discussion sessions, and ice-skating to get into the winter spirit! We @saterialelab.bsky.social can't wait.

My background is in molecular microbiology and parasitology, with a focus on malaria drug resistance. I’ve worked across international collaborations, mentored, and published in high-impact journals. Open to research, project-management, or education-focused roles in academia, govt or industry.

I’ve recently been made redundant from my role at UNSW due to the NIH’s decision to cancel foreign subawards. It’s an unfortunate situation affecting a lot of great researchers, and I’m now on the lookout for something new. If anyone knows of any molecular biologist roles coming up, let me know!

Oh, and a big thank you to our reviewers! The paper really benefited from them pushing us to explore and contextualise the data more deeply, so we thank them for their contributions and acknowledge their labour for the science we all love.

In these taxing times, I can only say that I count myself extremely fortunate to get to do what I love with people who make it worthwhile. I would not be here if not for them. I hope I can continue to do so and bring more people along on this continuing Crypto voyage.

Thankful to everyone in @saterialelab.bsky.social for making this journey so enjoyable, especially to Adam for giving me a shot on this huge project and guiding it through to the end. And of course the High-Throughput Screening team @crick.ac.uk for their invaluable expertise

We used this large dataset this created to discover some interesting host cell biology, unexpected Crypto biology, and even potentially a new host-directed treatment for this deadly disease. You can read the full thread about our findings here: bsky.app/profile/ghos...

We asked what happens if you disable almost every protein-coding human gene by CRISPR-Cas9 one by one in epithelial cells, infect those cells with the intestinal parasite #Cryptosporidium, and observe the resulting infection phenotypes by high-content microscopy to map the parasite's dependencies.

For those interested in Masters in lab and field based research in infectious disease we have 3 fantastic programmes to choose from MSc Immunology, medical parasitology and entomology and medical microbiology. They benefit from very flexible module choices and summer projects in UK and abroad!

Open call: If you are a researcher working on a project estimating a cause-specific burden of disease attributable to climate change at regional to global scales, please reach out! We're looking for researchers who might be interested in joining a new collaborative network / workshop series.

Precision-edited histone tails disrupt polycistronic gene expression controls in trypanosomes - Nature Communications Transcription in trypanosomatids, such as Trypanosoma brucei, is predominantly polycistronic and involves unconventional RNA polymerase II promoters.

I used inducible CRISPR/Cas9 to make Trypanosoma brucei cell line that allowed me to edit originally muti-copy histone gene. We uncovered a novel role of H4 histone tail in gene regulation. I enjoyed working on this exciting project with @joanarcf.bsky.social, a great mentor.

Omaya Dudin Interview with Omaya Dudin, who uses Ichthyosporea as models to study how and why unicellular organisms evolved multicellularity at the University of Geneva.

90% of you probably don’t need to read this.
But maybe some of you are curious & 10% will feel seen. Or a little less alone. This isn’t about seeking sympathy.
It’s about sharing something hard to say out loud;
partly to heal, partly in case someone needs to hear it too. (1/3)
