Excited to share this preprint that describes my latest work on using GPUs to accelerate processing of RNA-seq data.

The title says it all: "RNA-seq analysis in seconds using GPUs" now on biorxiv www.biorxiv.org/content/10.6... and github github.com/pachterlab/k...

Figure 1 shows they key result

This smells distinctly like collider bias and/or selection bias and/or regression to the mean... You simply can't select teen prodigies, and world class athletes rom databases, and go run regressions without serious consideration of the selection process!

OK, this is wild.

In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.

It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.

What the HELL?

RFK Jr talking about the need for doctors to know how to treat measles for those who are unvaccinated.

“Only very sick kids should die from measles.”

No. They shouldn’t. That was the point of the vaccine. We eradicated the virus so children didn’t die.

Sick & disabled kids are not expendable!

Explosion of formulaic research articles, including inappropriate study designs and false discoveries, based on the NHANES US national health database The combination of AI and national health databases offers opportunities, but may also be exploited by unethical agents. This study shows that there has been an explosion of formulaic research article...

In PLOS 🧪, discover AI-based data dredging, and health science paper mills fueled by on-demand misleading results at an industrial scale.

There is something refreshingly honest about moving the goalpost this blatantly. Adjusting for multiple testing? Not in my house ☝️

If the NIH gets messed up, there is no alternative. Not just in the US, but globally. It is by far the biggest engine of health research in the world. Which is why the idea that US scientists can just do their work elsewhere is a little fanciful.

Ég styð Magnús Karl sem rektor HÍ og hvet öll á kjörskrá að gera slíkt hið sama.

-HÍ þjónar samfélaginu með því að gera það sem hann á að gera vel: rannsóknir og kennsla

-Rektor þarf að hafa burði til að berjast fyrir skólann

-Magnús hefur spilað í efstu deild rannsókna, veit hvað þarf til

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.
