The UKB 1/2 million (of which I am one) are indeed reasonably investigated, but in comparison to the ALSPAC cohort - who were recruited as foetuses and followed up into middle age - what I've had done in UKB is tiny. ALSPAC has 3 generations too. We need both study types! www.bristol.ac.uk/alspac/

New paper on everyone’s favourite topic, QC!
We show why you should do genotype-level QC on your WGS data

Very real quotes about this paper -
“The most exciting, mind-blowing paper of the year!”
“On a par with Fisher 1918”
“I read it every night. Just so beautiful”
Genotype-level quality control substantially reduces error rates in population-scale whole-genome sequencing
Population-scale whole-genome sequencing data will contain many individual-level genotype errors, even after allele-level quality control (QC). We establish the need for genotype-level QC using UK Bio...

Galton calling for data sharing in 1901 - does anyone know of earlier examples?

Are there earlier occurrences of groups being established to archive biological data to make them available for future analyses by researchers than this, which is from The British Association Committee on Biological Measurements, 1927?

Met @mendelrandom.bsky.social at a pub in Bristol after my talk yesterday to chat about causality, ratio variables, and the state of Epidemiology in Europe.

Behind him, on the bookshelf, was an old copy of Mendel's Principles of Heredity. A remarkable coincidence that required a photograph!
