Trump team axes contracts with publishing giant Springer Nature The action comes as high-ranking US officials criticize top journals as β€˜woke’ and β€˜corrupt’.

”All contracts with Springer Nature are terminated or no longer active. Precious taxpayer dollars should be [sic] not be used on unused subscriptions to junk science.” the NIH spokesperson said. www.nature.com/articles/d41...

There are no h-index requirements. We will assess your proposal, CV, and the eligibility requirements (e.g. max 7 years after PhD with time allowed for certain activities). The key is to adress an important challenge, with a novel approach, reasonably feasible. But each position has its own profile!

Single-step discovery of high-affinity RNA ligands by UltraSelex | Nature Chemical Biology Aptamers, nucleic acid ligands targeting specific molecules, have emerged as drug candidates, sensors, imaging tools and nanotechnology building blocks. The predominant method for their discovery, systematic evolution of ligands by exponential enrichment, while successful, is laborious, time-consuming and often results in candidates enriched for unintended criteria. Here we present UltraSelex, a noniterative method that combines biochemical partitioning, high-throughput sequencing and computational signal-to-background rank modeling for discovering RNA aptamers in about 1 day. UltraSelex identified high-affinity RNA aptamers capable of binding a fluorogenic silicon rhodamine dye and two protein targets, the SARS-CoV-2 RNA-dependent RNA polymerase and HIV reverse transcriptase, enabling live-cell RNA imaging and efficient enzyme inhibition, respectively. From the ranked sequences, minimal aptamer motifs could be easily inferred. UltraSelex provides a rapid route to reveal new drug candi

Discover aptamers faster! UltraSelex combines partitioning, high-throughput sequencing & computation in 1 step. Revolutionize drug discovery! PMID:40164941, Nat Chem Biol 2025, @nchembio https://doi.org/10.1038/s41589-025-01868-6 #Medsky #Pharmsky #RNA #ASHG #ESHG πŸ§ͺ

So we’ll be vibecoding science soon enough, and not just for DNA! The AI models need access to all of the literature, code and data of course. We’ll have to build fully autonomous labs for all common types of experiments. And then we hook it all up in a loop. Exciting times!

In all seriousness though, the tools already know enough of the literature to develop novel ideas, and can definitely reason about how to design DNA vectors and perform experiments. They just fall apart when actually writing DNA or protein sequences. That’s fixable.

New paper out in @pnas.org

We followed cells migrating along signalling gradients in 3D, and found they collectively behave as a living droplet - a self-propelling fluid that grows.
