The Promise and Limitations of Metabolic Trait Prediction Across Diverse Bacteria
Predicting metabolic capabilities of environmental bacteria holds great promise for microbial ecology, but the reliability of available tools is often unclear. This perspective suggests that phenotyp...

"Depending on how you count, I have held six postdoctoral jobs. All asked the same thing: move across the country or the world, learn a new institution, and be productive immediately. This article is about what this costs postdocs, and what it costs both the present and future of science"

This release of Meta documents is a deeply shocking look at how tech tries to steer & control science. It's normal for crisis comms teams to ask how to counter scientists who criticize their employers. But here's what's especially shocking in these docs: cailinoconnor.substack.com/p/its-now-of...

More importantly, what happens to the scientist? Doing the work is how we develop intuition. Wrestling with data teaches you what is strange about it. Writing forces you to discover holes in your argument. Reviewing other people’s work sharpens your sense of what makes an explanation convincing. 6/7

Physiological trade-offs make traits costly, but resource requirements vary. This study by @sarperotto.bsky.social @javadmeghrazi.bsky.social &co uses a unified energy-proteome allocation framework to predict costs and growth across environmental conditions. 🧪 #AcademicSky plos.io/4k5TlUA

Thanks for starting this important conversation @blekhman.bsky.social ! The only thing I would have added is the goal of improving ecosystem health (independent of its effects on human health).
Ran Blekhman@blekhman.bsky.social · 3w agoSome of my thoughts about the surge in AI-generated papers, why this feels like a completely new kind of problem, and what this means for how we evaluate science in biology. Out now in PLOS Biology: journals.plos.org/plosbiology/...
This is a truly startling paper. It shows that mRNA can perform regulatory functions *in addition to* its role in encoding a protein. In other words, the distinction between protein-coding RNA and noncoding regulatory RNA is fuzzy. /1 www.science.org/doi/10.1126/...
