I could go by my middle name next time I visit (Daniel). It was the name I used to use as a kid when I was pretending to be someone else…

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.

It is depressing, but all too predictable, how swiftly we’ve gone from the Social Science Genetic Association Consortium offering reassurances about the uses of behavioural polygenic scores to one of their lead authors marketing embryo selection for IQ

A few thoughts on Herasight, the new embryo selection company. First, their whitepaper (drive.google.com/file/d/1EpFi...) implies that competitors like Nucleus have been marketing and selling grossly erroneous risk estimates. This is shocking if true! 🧡

The massive list of suspended UCLA grants came out today: 300 NSF and 500 NIH grants. I am miraculously not on the list, but this is devastating. Science will be lost, progress will be frozen, people will lose jobs, and careers in science and medicine are being destroyed. This is not ok.

Jay Bhattacharya once studied health disparities. As NIH director, he’s allowed such research to wither Jay Bhattacharya’s tenure as NIH director has seen health disparities research swept up in the Trump administration’s attack on DEI

My brother did not ask me to do this, nor did he know I was going to, but I made him a mashed potato volcano for his birthday.

The number of potatoes this required was shocking but otherwise it was relatively simple to do. A side effect is a freezer full of leftover mashed potatoes.

I use the built in Apple calendar, and have a calendly account set up for people to book different kinds of meetings. It has been working for me! My challenge is that I have a lot of calendars to manage for family/work… and they are all on different systems that don’t like to talk to each other! GL!

First copies of my book are here!! As a new faculty member, I realized that in addition to my research job, I also had a leadership job…and I wasn’t prepared for that.

This book is the guide I wish I’d had then, with the goal of helping others now.

This one was not NCI. NHLBI, and was 6%ile. I am a subcontract on another R01 that was 4%tile through NIGMS, but was told they will not fund it to focus on R35s, which generally do not allow subcontracts… so that one is dead unless we can transfer to another institute… good luck!!
