people getting upset about this is so crazy. bsky needs to become more than just a liberal politics app. doesn’t mean it needs more nazis & right wingers, just means it needs less politically focused users. it’s not good to be in your own little bubble, can’t have change with nobody to influence.

Bluesky's new CEO Toni Schneider on the platform's reputation for being a liberal bubble: "Yes, we definitely want that to change. It is already changing. It certainly wasn’t designed to attract one specific group of people."

a university is not for generating profit, it provides cultural enrichment via weird little gremlin people who love visigoths or haikus, and very occasionally a scientist who figures out faster than light travel

“Seven days after the girl’s medical team infused trillions of viruses carrying the recipe for the base editor into her spinal fluid, she died of a severe immune reaction linked to the therapy…” This, in @science.org, is an important and tragic story. (It’s also an incredibly well reported one.) 🧪

New preprint from my lab with a methodological follow up on our work on fast GSEA algorithm: Hash-augmented adaptive multilevel splitting Monte Carlo algorithm for accurate estimation of two-sample permutation test p-values 1/7

Preprint abstract:

Nonparametric permutation tests are widely used for statistical analysis. However, exact computation of test p-values can be algorithmically challenging, particularly for custom tests with complex test statistics. In contrast, Monte Carlo sampling can be easily applied to any test statistic, but it suffers from poor relative accuracy when estimating small p-values, interfering with multiple hypothesis testing correction and leading to other issues. In this work, we present a hash-augmented adaptive multilevel splitting Monte Carlo algorithm that enables accurate estimation of arbitrarily small p-values in two-sample permutation tests. Using the Kolmogorov-Smirnov and the Mann-Whitney U tests as examples, we highlight potential pitfalls related to the discreteness of the test statistic distribution and show how to address them. By comparing with an exact algorithm, we demonstrate the accuracy of the p-value estimates provided by the proposed algorithm and the validity of the associated confidence intervals. We provide a reference implementation of the proposed algorithm in the Python package hamstest, which allows p-value estimation for a user-defined statistic.

(1/10) The majority of human genetic variation is located in non-coding regions. The great challenge of the post-genomic era is to assign function to these variants. We reasoned that combining haplotyping with allele-specific multiomics can help pinpoint the functional ones: rdcu.be/fgr5W. A thread:

I just made this bot that posts links published papers related to neurodegeneration. (Same template that I used for preprints, just took me a while to get around to the papers one...) I think I've covered the major journals and diseases, but let me know if you think something is missing :)

But I'm afraid that people will read this differently as a claim that RCTs are not the best tool available to arrive at an unbiased estimate of the effects of a clearly defined medical intervention, and that observational causal inference has gotten so good they've become superfluous. They haven't!
