Chronic diseases were more strongly linked to suicide attempt, while severe conditions and psychiatric polygenic scores were more associated with suicide, indicating overlapping but distinct risk factors for attempt and death by suicide. https://t.co/0BKIBCHPZo

🧬💥 Do the genetics that make you develop a disease also help you survive it? Not much. Our new @NatureGenet including 9 disease and 7 biobanks shows: • Susceptibility variants ≠ survival • PRSs for onset weak at predicting survival • Lifespan PRS predicts survival better

Oof. Polygenic scores for IQ lose 75% of their explained variance when adding family controls, even worse than the attenuation for Educational Attainment. These are the scores Silicon Valley is using to select embryos 😬. A few thoughts on this study ...

It's amazing how Trump just made the Euro strengthen by more than 2% in one day, and with it the size of the EU economy.

russia is not on the US tariff list because the US does not trade with russia, says the US Treasury Secretary. In fact, they do trade, even more than with Mauritius or Brunei, for example, which were added to the tariff list. Cuba, Belarus, and North Korea were also not

I wrote about how population stratification in genetic analyses led to a decade of false findings and almost certainly continues to bias emerging results. But we are starting to have statistical tools to sniff it out. A 🧵:

The top 0.1% of Americans control $22 trillion in wealth. The bottom 50% of the country controls $3.8 trillion in wealth. Read that back. Is it any wonder why so many think the system is rigged?

Canada is starting to get really angry at Trump. Their Foreign Minister Melanie Joly is serious about standing up to Trump's attempt to annex her country and doesn't think it's funny. "If the U.S. can do this to us, their closest friend, then nobody is safe." She also

@atrupar This is a Norwegian Church in Greenland. A wedding in 1408, between Sigríður Björnsdóttir and Þorsteinn Ólafsson. The Curch is much older. How old is the US again?
