“Seven days after the girl’s medical team infused trillions of viruses carrying the recipe for the base editor into her spinal fluid, she died of a severe immune reaction linked to the therapy…” This, in @science.org, is an important and tragic story. (It’s also an incredibly well reported one.) 🧪

Is the real issue less a guilty/not guilty verdict but - as in Tessier-Lavigne’s case - the fact this seems bound to occur in a hypercompetitive environment incentivizing fraud and a feudal system ill-equipped and disincentivized to address it?

Neuropathologist Adriano Aguzzi is not guilty of research misconduct or negligence, a probe of three dozen studies at the University of Zurich has found. My latest for @thetransmitter.bsky.social: www.thetransmitter.org/ethics/neuro... @elisabethbik.bsky.social, @charlespiller.bsky.social

The Thermo Fisher situation keeps getting worse. We've now collected 450+ problematic images presented as verification data in TF's antibody catalog. This includes: 🖌️ Dozens more images with duplications or painting 🖨️ Hundreds of blots that all share the same background (behold slideshow below)

Exciting news 📣 The first preprint from @grandlab.bsky.social is out 🧬 How are essential genes controlled? By rapid degradation and recovery of TFs alone or in combination, we show that essential genes rely on a single dominant TF, despite dense co-binding. www.biorxiv.org/content/10.6...

Essential genes are dominantly activated by single transcription factors

Cell viability depends on the precise expression of essential genes, which are controlled by CpG-island (CGI) promoters densely bound by transcription factors (TFs). This has led to the prevailing model that TFs cooperate to ensure ubiquitous expression. Here, using rapid and reversible single and combinatorial degradation in murine stem cells, we systematically dissect the regulatory interactions between five key TFs. We uncover an unexpectedly specific architecture in which regulatory dominance, rather than cooperation, is the prevailing mode, where individual TFs autonomously drive chromatin opening and gene activation at largely distinct promoters. Cooperative regulation occurs at a minority of sites with antagonistic or synergistic outcomes modulated by the interplay between nucleosome positioning and TF sensitivity to chromatin. This logic is recapitulated at synthetic sequences and reflected in human genetic variation. These findings reveal that single TFs dominantly activate distinct sets of CGI-linked genes, including essential genes, across development, homeostasis, and disease. ### Competing Interest Statement The authors have declared no competing interest.

Kejelcha broke the 2-hour marathon barrier on Sunday 🤯. He came second and barely made the news. In science, we'd call that getting scooped. But science is not elite sport. It's not a zero-sum game. A "winner takes all" attitude actively discourages a pillar of good science: independent replication.
