Does anyone have a high-res version of NCBI GEO logo (www.ncbi.nlm.nih.gov/geo/img/geo_...)? I hate putting their low-res version in the slides/figures. I've tried to use AI tools for upscaling, but the results aren't perfect (colors are off). Anyone want to take a shot at it? Here is my best take:

Somatic mutation and selection at population scale - Nature A new version of nanorate DNA sequencing, with an error rate lower than five errors per billion base pairs and compatible with whole-exome and targeted capture, enables epidemiological-scale studies of somatic mutation and selection and the generation of high-resolution selection maps across coding and non-coding sites for many genes.

ohhhhhhhh wow

Redid this thanks to @james-gagnon.bsky.social reminding me about NIH Databook. R01 applications numbers are dropping greatly at NIGMS but success rates (after being flat) dropped greatly last year. Suspect this will be even more drastic in 2025

I believe you can submit multiple grants to NIGMS in parallel, you just had to withdraw other applications to get awarded, no? Which doesn't sound too bad, because it means you are getting a grant.

One of them should be 5e-324. Another - maybe 1e-300 as a rounding of that? And maybe 1e-200 as another capping threshold?

An array of 9 purple discs on a blue background. Figure from Hinnerk Schulz-Hildebrandt.

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.

The effect presumably comes from the absence of S-cones in the fovea.

Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change.

Ie: it's not us (Samtools team)! Be warned

Oh, fun: Someone did some personal science to evaluate if _they personally_ benefit from "AI", and this is what they found:

Β«Yes, it’s a limited sample and could be chance, but also so far AI appears to slow me down by a median of 21%, exactly in line with the METR study. I can say definitively […]

An important milestone for me and my lab: fgsea has passed DESeq2 on the list of most downloaded Bioconductor packages. It started as a side project during my PhD, back when DESeq2 was already a staple of RNA-seq analysis. I never even thought it could go this far β€” but here we are!

A screenshot of a graph of water levels from a station in Hawaii as the tsunami impacted the region.

Does water always recede prior to the arrival of a tsunami?

I was asked this yesterday after posting a graph of observed water levels at a station in Hawaii, which shows water levels first *increasing,* contrary to what many have heard about tsunamis.

The answer: no, not always! A thread... 🧡 1/9
