The strongest predictor of autism is genetics.

Data:
• If one identical twin has ASD, the other has a 90–99% chance.
• Compare that to 31–67% chance for fraternal twins.
• Non-twin siblings have ~20% likelihood of ASD, 7-fold higher than general population.

Wow...what? Apple does protein folding now? As the name implies, it is a "simple" and general-purpose transformer-based method, which relies on a non-domain-specific flow-matching objective rather than domain knowledge.

Such an amazing method and such a good study! Have to read it more carefully, but shows huge potential. Combining evolutionary and population genomics + language model is a great idea.

I'm a science journalist for @statnews.com looking to talk with folks who applied to biomedical Ph.D. programs and had offers rescinded earlier this year. What have you been up to since then? You can reach me at [email protected] or via Signal (username jwosen.27). #journorequest

Nothing beats the elegance and simplicity of AUC with confidence intervals. AUPRC is useful, but it looks jagged and the baseline is cohort-specific.

I am not sure why a blog post is paywalled.

Our paper benchmarking foundation models for perturbation effect prediction is finally published 🎉🥳🎉

www.nature.com/articles/s41...

We show that none of the available* models outperform simple linear baselines. Since the original preprint, we added more methods, metrics, and prettier figures!

🧵
Beeswarm plot of the prediction error across different methods of double perturbations showing that all methods (scGPT, scFoundation, UCE, scBERT, Geneformer, GEARS, and CPA) perform worse than the additive baseline. Line plot of the true positive rate against the false discovery proportion showing that none of the methods is better at finding non additive interactions than simply predicting no change.

This is a pretty stark reminder that every methods paper needs proper baselines: "We compared five foundation and two deep learning models against deliberately simple baselines for predicting transcriptome changes after single or double perturbations. None outperformed the baselines."

RNA for the win! The once-overlooked black sheep of the macromolecules is slowly yet surely claiming its rightful place and prominence.

Didn't know Ben Blencowe has a part-time appointment at Crick! Should be a productive collaboration!

Meet Jernej Ule (@ulelab.bsky.social) and Ben Blencowe, who set up the Brain RNA Regulatory Networks satellite lab here at the Crick.

We spoke to Ben and Jernej about their research into RNA auto-gated vectors and their potential applications in gene therapy.

I asked ChatGPT to summarize this article and this is what it came up with: "Overall: AI itself isn’t the problem—it’s the hype, incentives, lack of accountability, and cultural shifts that could slow meaningful science."

I think it is a pretty good summary.

How did the pandemic start?

I have avoided publicly commenting on this for 5 years. Here's my take as someone who has no stake at all in the game.

The first draft of the human genome turns 25 today! 🎂

On 26 June 2000, the UK & US announced the first full map of the 3 billion DNA base pairs that make us human.

🌍 A milestone for humanity, powered by global collaboration.

Allowing Netanyahu to drag us into another endless war in the Middle East would be a catastrophic error by President Trump and Republicans in Congress.

Every lawmaker needs to ring the alarm against U.S. military action in Iran. Only Congress has the authority to declare war.

Less than 200 years ago, one in three Dutch children died before the age of five
A line graph illustrating the estimated share of newborns in the Netherlands who die before reaching age five from 1840 to 2023. The y-axis represents the percentage of children dying before age five, ranging from 0% to 40%, while the x-axis shows the years from 1840 to 2023.

The graph has a prominent downward trend, indicating a significant decline in child mortality rates over time. Key data points are highlighted: in 1840, around 40% of children died before age five, peaking around 1959, where 39% of Dutch children died before this age. A notable decrease begins after 1960, reaching about 10% in 1945, where 1 in 10 children died. In the latest data for 2023, this figure has improved to 1 in 250 children dying before reaching age five.

Annotations on the graph provide contextual information, linking past statistics to present outcomes. The data sources listed at the bottom include Gapminder (2015) and UN IGME (2025). The design is attributed with a copyright notice indicating CC BY
