New preprint on the limits of detecting higher-order interactions in microbial communities.

We find that the dominance of additive and pairwise interactions on community function may not reflect biological simplicity, but fundamental limits of statistical detection.

A study of social media content 18-24-year olds see in #Finland, #France and #Romania shows that algorithms overwhelmingly feed them right-wing political content - whether or not the users are interested.

Three country average for right wing content was 58% - in Finland, 67%!

Do obesity drugs treat addiction? Huge study hints at their promise Study of 600,000 US military veterans shows that those who took anti-obesity medications were less likely to develop some complications of substance-use disorders.

GLP-1 medications might help people avoid becoming addicted to drugs, including alcohol, cocaine, and opioids

We are very excited to share a new resource from our team: spatial subcellular proteome maps in plants! We developed an MS-based method that registers localizations of about 8000 proteins in Arabidopsis roots in a single experiment.

With Eugene Koonin, we propose a concept of β€œthe selfish ribosome”, under which evolution of life is viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensures the propagation of the ribosome. arxiv.org/abs/2602.23268

Benchmarking EGF signaling pathway inference using phosphoproteomics and kinase-substrate interactions - Nature Communications To what extent can large-scale approaches accurately reconstruct classic signaling pathways? Here, authors revisit the EGF pathway using phosphoproteomics and kinase-substrate interactions

Interested in kinase-driven signaling interactions? Check out our (now peer-reviewed) paper together with @savitski-lab.bsky.social on reconstructing signaling networks from phosphoproteomics data and prior knowledge:

It was a very cool experiment! The author-centric perspective makes a lot of sense.

An important next step is to benchmark multiple AI review platforms. Maybe this can also pave the way for benchmarking human peer review across journals and defining "quality features" of the peer review process.

Restoring the tumour mechanophenotype of vocal fold cancer reverts its malignant properties - Nature Materials Vocal fold cancer tumours lose some of their malignant traits when mechanically stimulated by physiological stretch or vibrations, mimicking the opening and closing of vocal folds and phonation.

What music should we play to our cells? This was the start of an amazing journey from @ivaskalab.bsky.social at @turkubioscience.bsky.social with Jasmin Kaivola and collaborators @sarawickstrom.bsky.social and others to explore larynx cancer mechanosensitivity!
