Our latest paper has just been published in Cell! doi.org/10.1016/j.ce... We developed a new method called MCC ultra, which allows 3D chromatin structure to be visualised with a 1 base pair pixel size.

Not from Tron or a psychedelic wallpaper. This exquisite pic reveals chromatin at base-pair resolution, captured by #ListerFellow James Davies and collaborators🤩 "For the first time, we can see how the genome's control switches are physically arranged inside cells." @jojdavies.bsky.social

Feeling exhausted after a fantastic but (as always) full-on #ashg25 . Great to catch-up with so many folks! So long Boston, for a little while at least...

Planning your afternoon poster session at #ashg25? Come say hello! This is an amalgamation of our two recent preprints - working with @gregfindlay.bsky.social , @cassimons.bsky.social , @dgmacarthur.bsky.social and many others to study variation across RNU4-2 and describe a new recessive NDD 🧬

At #ASHG25? Go chat to super⭐ PhD student Anthony at his poster this afternoon 👇

At Heathrow about to board my flight to Boston for #ASHG25 #ASHG2025 (which are we using?). I am super disorganised with planning (please do reach out if you want to meet up), but looking forward to catching up with folks over the next few days!! ✈️🧬🤓

If you’re applying to your dream lab for an internship/PhD/postdoc, always send a second email 1-2 weeks after the first one if you don’t hear back. I promise we will be grateful rather than annoyed. My email inbox is a disaster and I’m quite junior - and very few of us have secretarial support

In reporting this piece on the new trial for a Huntington's treatment, I was struck by one thing in particular: The joy. One of my sources wept for joy. He has spent his entire career studying this disease, he said it was the happiest day. www.sciencenews.org/article/hunt...

We now have an open post-doc position in the lab: crick.wd3.myworkdayjobs.com/External/job... Please apply if you have a background in functional genomics or a related field and are eager to develop methods to map variant effects at scale.

While I was taking a holiday last week, 2 super exciting preprints dropped, adding to another posted 6 days prior. These papers describe a remarkable role for *recessive* variants in *RNU2-2* causing developmental and epileptic encephalopathy 🧵 by the amazing @christeldepienne.bsky.social 👇 1/3

So proud of two postdocs in the team @alextremophile.bsky.social and @ruebenadawes.bsky.social. My role here was one of 'chief cheerleader' with this work truly led by these two superstars 🤩 The key take-home: be careful when using SpliceAI precomputed scores. Why? Read Alex's 🧵to learn more. 🧬💻🩺

1st Bluesky post with recent updates: 1/3 It was incredible to attend and speak at the ReNU Hope Conference in Long Island, NY. This was the first time I met the families and the ReNU warriors, sharing many touching stories. I hope to continue advocacy in China where few are currently diagnosed.

👋

Just over a week left to apply for these positions - deadline on Thursday 28th August 👇

#veryBritishProblems at #eshg2025 - trying to source hot water for my stash of tea bags... 😬 Anyone have any tips, I would love to hear them! (exhibition hall has only pre-made tea 🤢). I am not sure asking a random worker to wander off and fill my keep-cup is a sustainable strategy 🤣

🗣️ Quote of #ESHG2025 (so far) "Who licks bone !?!" 🦴 - Johannes Krause Anyone have that on your bingo card? Well apparently archeologists do, to distinguish bone from stones and it causes problems in DNA sequencing. 🤔

Now on in Gold #ESHG2025 Yuyang Chen @nickywhiffin.bsky.social and using Ribo-Seq to identify small ORFs important in #raredisease 🔍🧬 multiple new diagnoses found, due to both novel and recurrent variants
