#AI may indeed exacerbate our bad academic habits: #LLM science summaries were nearly five times more likely than human-authored science summaries to contain broad generalizations (95% CI [3.06, 7.70], p < 0.001). And newer models over-generalized more; not less! doi.org/10.1098/rsos... #philSci

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!

Have you ever wondered: just how strong *is* the evidence for Muller's ratchet on mtDNA? Well, wonder no more! (Project led by Yu Mo, with @smishra677.bsky.social and @yadirapga.bsky.social) "No molecular evidence for Muller's ratchet in mitochondrial genomes" www.biorxiv.org/content/10.6...

Happy to share my work with my advisor Zachary Szpiech! Why are associations between ROH & complex traits inconsistent across studies? We use realistic simulations to show how demographic history and genetic architecture interact to shape the phenotypic impact of ROH. www.biorxiv.org/content/10.6...

As I told the CNN, without details and data it is not possible to assess the claims. More importantly, the scientific value of this media campaign, balanced against the possible stigmatization of individuals with these real conditions today, is highly questionable. edition.cnn.com/2025/11/13/s...

Putting aside the deeper issues of why this analysis was done and how it has been promoted, the choice to broadcast a tv show before releasing a preprint should make people skeptical of the results. How can one be sure of their scientific claims?

Scientists used to think diseases that jump from animals to people really took off when people started domesticating cattle, sheep and goats 11,000 years ago. A new look at ancient bacterial DNA in @science.org by @poojaswali.bsky.social and colleagues suggests the pivotal moment came much later.

Our papers, out today in @nature.com, show how ancient DNA from the Eneolithic and Bronze Age steppe points to a North Pontic origin of the Indo-European language family and a Caucasus-Lower Volga (CLV) origin of Indo-Anatolian (inclusive of the now extinct Anatolian languages). 1/
