J-PEP is a new method that clusters disease-associated loci by combining pleiotropic SNP effects with tissue-specific epigenomic data. It improves biological resolution across complex traits.

If we take regional averages, genes associated with education predict height better than genes associated with height. Why? On a regional level, education-associated genes pick up environmental differences between richer and poorer neighborhoods πŸ§¬πŸ’°

A line graph titled "Confirmed cases of influenza B Yamagata" shows weekly confirmed cases of B Yamagata influenza worldwide from various types of influenza surveillance. The vertical axis represents the number of cases, ranging from zero to 5,000, while the horizontal axis covers the years from 2013 to 2025. The graph indicates significant fluctuations in case numbers over the years, with a noticeable peak just below 5,000 cases around 2019, followed by a steep decline. A data source note mentions that only a fraction of potential influenza cases is tested by labs for confirmation and strain identification. The data comes from FluNet, World Health Organization, and is dated 2023. The graph is licensed under CC BY.

I can't believe we're still allowing completely inadequate and uninterpretable Epigenome-Wide Association Studies (EWAS) to be published.

I don't care that this study is probably well-intentioned, and probably trying to draw attention to awful events in Syria.
