Campolina: a deep neural framework for accurate segmentation of nanopore signals - Genome Biology Nanopore sequencing enables real-time, long-read analysis by processing raw signals as they are produced. A key step, segmentation of signals into events, is typically handled algorithmically, struggl...

sequencing accuracy, but at a cost to portability due to GPU demands.
Our new work, spearheaded by

Last day at #InSiGHT2026 with a session for Early-onset colorectal cancers that I had the pleasure to co-chair. Thank you for thoughtful discussions with the speakers & audience !

Lastly, thank you for the support from @nanoporetech.com on the project and more updates to come!

Day 2 at #InSiGHT2026 with thought provoking talks on the molecular features of Lynch Syndrome. Thankful for the opportunity to give a talk in collaboration with Illumina Simeen and Shunhua Han on the newly released TruPath Genome.

Looking forward to the next 2 days of talks!

Excited to see this thought provoking piece of work now published. So much more to learn about mutagenesis in healthy tissue.

Black and white portrait of John Gurdon, 1971

John Gurdon, former Group Leader and Head of @cellbiol-mrclmb.bsky.social has died.
Despite calling himself a "total non-intellectual” his work to reprogramme somatic cells to pluripotent stem cells transformed the field of developmental biology.

Rest in peace Jane Goodall, a true giant among scientists. Your breakthroughs into the secret lives of chimpanzees viewed through an anthropomorphic lens – without yet knowing that science had forbidden it – changed science forever, and with it how we see ourselves.

Elegant work to unveil the etiology behind the ubiquitous SBS5 mutational signature. Glad to be in the audience to see this work presented and I have already put it on my reading list.

The Somatic Mosaicism across Human Tissues Network - Nature The Somatic Mosaicism across Human Tissues Network aims to create a reference catalogue of somatic mosaicism across different tissues and cells within individuals.

We are all somatic mutation mosaics.
"There are trillions of cells in a human body and so the total number of somatic mutations acquired in a single individual may well exceed quadrillions, millions of times the size of the human genome."

If you don’t have time to take a walk, then you don’t have time to do science. Charles Darwin would take two walks every day on his "thinking path", not as a break from science, but as a crucial part of it.

Eugenics is on the rise again: human geneticists must take a stand Scientists must push back against the threat of rising white nationalism and the dangerous and pseudoscientific ideas of eugenics.

“If left unchallenged, a rising wave of white nationalism in many parts of the globe could threaten the progress that has been made in science — and broader society — towards a more equitable world,” writes Genevieve Wojcik in a Comment article for Nature. 🧬 🧪

A wonderful reminder that my time spent comparing all the ecDNAs in organoids from the @RFitzgerald_lab added new insight to how we can use tumour organoids as a model to study ecDNA.

And so it begins. I have been working in genomics / sequencing for more than 30 years but today is a particularly exciting day as I begin training on using the @nanopore MK1D sequencer which we will be using soon for student projects (and other things) at @ucdavis.bsky.social
