I'm excited to share that my newly funded #ERCStG FRONTERA is recruiting two postdoctoral researchers at @ipbhalle.bsky.social 🌱🔬 If you are passionate about plant immunity, proteolysis, membrane proteins, or proteomics, I'd love to hear from you. 🧵 Please RT/share!

Group Leader @ BIH Berlin and MPI Molecular Genetics. I play around with DNA because I‘d like to know how the genome functions.
Astrophotographer Adam (AJ) Smadi caught this image a few hours ago from Washington state. A thin crescent Moon, sunlight illuminating the rugged lunar surface. And 2,400 times farther away—and on the other side of the Sun—mighty Jupiter, and its moons Io (left) and Ganymede (right).
I AM SCREAMING NANOPORE! seriously, @nanoporetech.com: you eed to look into this for you lib prep & sequencing. it might make your tech way more reliable!
The lab is a mysterious place--where some people have "magic hands," and some experiments just won't work. Here's my story about the unspoken knowledge of science, and the struggle to share it. Gift link: nyti.ms/3UccF7Z
Excited to share our paper in @natgenet.nature.com on the de novo design of tissue-specific mammalian enhancers that function in vivo in mouse embryos. 🧬🐭 www.nature.com/articles/s41...
Breakthroughs like this rely on standing on the shoulders of giants. Beyond new DL models, this work was only possible thanks to high-quality epigenomic #ENCODE datasets and massive VISTA collection of validated enhancers built over 20+ years by @axelvisel.bsky.social, Pennacchio and Rubin labs.

the mechanism behind this is that if you don't do your homework you don't learn the topic
Woah.
Our work on the role of the proteasome in developmental tempo is out!!!! 🐭⌛️👤⏳ Six years after identifying an association between protein stability and developmental tempo, we now demonstrate a causal link between protein turnover and developmental tempo through proteasomal degradation

Must-know numbers in human genetics -- As many of you know, I'm writing a free online textbook in human genetics. In this blog post I cover a key skill for genome scientists from that book: how to use mental math to figure out key genome properties. jkpritchard.substack.com/p/on-fermi-p...

Finally… Excited to share what I’ve been working on for the first half of my PhD! ENCODE GRAMMAR: One of the largest collections of regulatory DNA seq2func models to date (3,865 in total) trained across ENCODE, with full model interpretations and annotations tracks. Blog: tinyurl.com/3hmknhaa 1/
really impressive scaling feat! i’m jealous of it. very neat assay, wonderful acronym. i’m all for it though lit refs could be better and are 5 x1kb fragments really a mammalian locus?
New preprint from Shendure Lab on Locus-Scale aka Long-@$$ MPRAs led by the amazing Abby McGee & @carinabiar.bsky.social Most MPRAs test ~300 bp fragments next to a promoter. But real enhancers are bigger, act combinatorially and from a distance. 1/n www.biorxiv.org/content/10.6...
Obviously a strong supporter of this type of tool, but troubled by the literature review. No reference to @chribue.bsky.social work on combinatorial enhancers, and our EXTRA-seq -> kilobase-scale E-P landscapes in a native locus (no minP). Same principle, just ONT.

When I was writing this piece about the Ocean Cleanup, I had a surreal experience: They assured me that they only kill invasive species, and sent me a published paper to demonstrate that. But the paper said the opposite! I wonder how many journalists just took their word for it and didn't check?

Global problems are rarely solved by one person or invention. The Ocean Cleanup didn’t work, for the reasons experts said it wouldn’t. What can we learn from this?

really good take from Aydan! I‘m also quite disturbed by the whole 1% marketing gag. masterful click-baiting as expected from oded (worked for me). but it kind of feels like a right out of a Black Mirror episode. As if it wouldn’t lead to a new glorification of articles ranked well by an AI.
I have been thinking since yesterday about why I find the 1% thing so, so disturbing. It's a visceral reaction of 'just no', which goes beyond the general yuck towards the enshittification of/via AI. I have finally put my finger on it: it is the feeling you get when

An historical figure of the transcription field has gone. Founder of @igbmc.bsky.social where I started my career. A great enabler as well.
#RIP Pierre Chambon (1931-2026) 1963 PARP 1970 RNA Pol II 1975 Nucleosome 1977 Split genes 1980 Promoter 1983 enhancer 1986 Nuclear receptor
Pierre Chambon was a great scientist. And a good man too. He alone opposed to leading British embryologists during the evaluation of a case of scientific misconduct more than 40 years ago, to defend young scientists against an establishment to which he belonged. An unforgettable lesson. RIP Pierre 💐
