How do GWAS and rare variant burden tests rank gene signals?

In new work @nature.com with @hakha.bsky.social, @jkpritch.bsky.social, and our wonderful coauthors we find that the key factors are what we call Specificity, Length, and Luck!

We're excited to share the final version of our paper, where we demonstrate how confounding remains a thorny problem for claims about causal genetic influences on human behavioral and socioeconomic outcomes. (w/ @jedidiahcarlson.com @oliviarxiv.bsky.social Ruth Shaw @arbelharpak.bsky.social) 🧵👇

These embryo-selection startups are clearly feeding into an alt-right ecosystem that revels in techno-futurism much as such movements have in the past. GWAS participants & parents navigating IVF deserve better than being used as tools to attract the attention of edge lords.

So when next we tell you that it's a terrible idea to fire your writers and editors and either a) hire some of them back as "assistants" to clean up LLM generated "AI" slop or b) just wholly rely on content mills which do the same, i want you to remember what's happening to the Chicago Sun-Times.
On Sunday, May 18, the print and e-paper editions of the Chicago Sun-Times included a special section titled the Heat Index: Your Guide to the Best of Summer, featuring a summer reading list that our circulation department licensed from a national content partner. 🧵

So exciting to see this out -- Michael has hugely accelerated my statistical training over the last few years and is incredible at explaining and teaching complex ideas in stats 👏🏻👏🏻👏🏻
My first textbook is officially available for pre-order today. Grab a copy if you're interested in developing a (statistical) research-oriented mindset. The book is designed as a stepping stone from statistical coursework to novel statistical research.

1. LLM-generated code tries to run code from online software packages. Which is normal but
2. The packages don’t exist. Which would normally cause an error but
3. Nefarious people have made malware under the package names that LLMs make up most often. So
4. Now the LLM code points to malware.
LLMs hallucinating nonexistent software packages with plausible names leads to a new malware vulnerability: "slopsquatting."
LLMs can't stop making up software dependencies and sabotaging everything

Wow. "NIH" canceled my co-mentored (with Dave Sulzer) PhD student's F31 funding. His work is on understanding the genetics and neuroscience of language learning disorders. F31 provides no indirect $ to Columbia, just pays his salary. Not that it should matter, but he's an American citizen. W.T.F.

While Trump seeks to undermine public education, Gov. Abbott is defunding and destabilizing Texas public schools.

Abbott's voucher scheme will serve less than 2% of our 5.5 million Texas public school children. $1 billion in taxpayer dollars wasted on a plan that fast-tracks mediocrity.
Texas bill that lets families use tax dollars for private schools swiftly sails through Senate
Senate Bill 2 now heads to the House, where top officials say they have the support to create education savings accounts.

Think of a polygenic score you care about. Are direct genetic effects driving variation among people in this predictor? Or perhaps other, confounding factors? We at the @arbelharpak.bsky.social & @docedge.bsky.social Labs developed a method to tackle this question. [1/n]

"grants are being reviewed independently by two staff members instructed to indicate any potential violations of Trump’s orders"
As the article says, these orders will likely be found illegal. Why is the NSF expediting this and why is anyone agreeing to reviewed already reviewed grants?
