In memory of Dónal Lunny, the greatest transition in Irish music history at 2:27. Nothing short of a musical genius, he will live forever. youtu.be/xB07-Cuh4Fo?...

At least this field of very squishy science is talking about being more rigorous. Notable omission -- if you have a phenotype that looks inherited, sequence the genome for a mediating genetic variant. DNA is a really good way of transmitting information between generations.

@mcuban.bsky.social seems like a good guy. This could be transformative for rare diseases. Mark Cuban wants to crack open the market for rare disease treatments www.statnews.com/2026/10/21/m... via @statnews.com

This sounds like a great opportunity. @institutcurie.bsky.social

A workshop, not a conference, challenging each other with new ideas and perspectives, thanks to @pablonavarrolab.bsky.social and co-organisers for convening this group in beautiful Baeza in Andalusia. www.unia.es/estudios-y-a...

The new @fontainesdc.bsky.social Fontaines DC album is very, very good. fontainesdc.x-l.co/dopaminecham...

New Yorkers, look out for Jordan from Clarecastle: "Jordan is described as being about 5ft 7in tall, of slight build, with light brown, shoulder-length hair and a beard. He has blue eyes and a piercing at the back of his neck." www.irishtimes.com/world/us/202...

Profoundly disturbing. When DNA methylation tests meet the garbage wellness industry. Zoltar’s advice outside the old Gem Spa in the East Village was about as valuable, and cost a lot less www.nytimes.com/2026/10/08/s...

Last week to apply for this. If you are interested in working on cool project to understand the role of DNA methylation in regulating transcription please apply!

This is a common Bronx story. People there do not deserve to live under such pressure when wealth abounds in NYC www.nytimes.com/interactive/...

Probability of Necessity www.medrxiv.org/content/10.6... among people who had the variant and developed the disease, the probability that the disease would not have occurred if the didn't have the variant. Low penetrance variants can have a high PN.

Thanks to @jkresovich.bsky.social for hosting me at @moffittnews.bsky.social, where I got to chat with colleagues about how we study ‘epigenetics’ in human diseases. Everything from cellular reprogramming to cell fate to functional non-coding variants. Jake looks ready to meet the challenges!

Congrats to my wife @drgmcginty.bsky.social, who ends up leading everything in which she gets involved! news.weill.cornell.edu/news/2026/09...

Disappointing but not the end of the road, good overview at @statnews.com After failure of Angelman syndrome drug, experts see hope in other experimental therapies www.statnews.com/2026/09/04/a... via @statnews.com

Just lovely. Horse racing on Omey Island in Connemara. #Homesick www.nytimes.com/2026/08/15/w...

Really looking forward to participating in this workshop: Transcriptional Memory in Health and Disease (if only because they were courageous enough not to call it 'Epigenetics' in Health and Disease) Great speaker lineup, workshop format, limited to ≤50 participants www.unia.es/estudios-y-a...

I like papers that look simultaneously thoughtful and useful, nice work from Alex Ioannidis and colleagues Multi-ancestry admixture mapping reveals ancestry-associated disease loci in the UK Biobank medRxiv. posted 10 August 2026, 10.64898/2026.08.06.26359859 medrxiv.org/content/earl...

Two weeks left to apply!

Come be our colleague. I have been in this Division for 27 years (4 as a postdoc and 23 as a PI). It is an amazing place to work, collaborate, and be inspired. If you are applying to be an Assistant or Associate Professor this Fall, don't miss this deadline.

I just realised that a couple of lovely people left 5-star reviews on Amazon for my book. I would like it to be known that neither of them was me. Thank you both, very kind of you. www.amazon.com/Epigenetics-... #epigenetics

The headlines are still covering the cyclosporiasis outbreak from lettuce, but let's talk about a different summer, long ago. The headlines in Bavaria would have called it "summer diarrhea" & it was killing babies. Enter our hero, Professor Theodor Escherich of the Julius Hospital, Würzburg.

I have to admit that I didn’t know, and I even thought the Spanish player Cucurella’s look was quite original, when it comes to his hair, but I was unaware of this: If he let his hair grow , it’s so that his autistic son can easily recognize him when he watches him on TV. Truly, this Spanish team ❤️

Hopefully this will provide a free link to a beautiful piece today by @fotoole.bsky.social (Support your local news media) archive.is/202607210554...

I should post another summary of something from my book. Any requests? I was thinking of an overview about DNA methylation, but open to other ideas. www.cshlpress.com/default.tpl?...

Very cool. NYC has a map for locating sites providing free N95 masks.
