🚨 New preprint from our lab at NIAID! We discovered hundreds of sRNAs and mapped RNA–RNA interactions in the Lyme disease pathogen, revealing a dynamic regulatory network and OspR, an sRNA that directly binds and downregulates the mRNA encoding OspA, the antigen used in Lyme disease vaccines! 🧬

Global RNA-RNA interactome mapping in B. burgdorferi reveals base-pairing sRNAs that rewire gene expression across growth

Small RNAs (sRNAs) are prevalent across the bacterial kingdom and produce diverse regulatory effects when base pairing with target RNAs. To better identify sRNAs, we designed an experimental and compu...

Your monthly reminder that if you're using ChatGPT to do your science, you're failing your colleagues, community, and all of us. Here, ChatGPT makes up data and presents it as the real thing — then apologizes when confronted.

For the actual figure, use matched populations and treatments in both panels, with means and uncertainty. The teaching point is immediate: hybrids survive better, but wild plants reproduce more—viability and fecundity selection oppose one another.















fucks sake don't make up the data














You’re right. You asked for a sketch from Mercer, and I gave you invented bar heights. Labeling them “illustrative” doesn’t make that appropriate. I should have obtained the actual data or told you I couldn’t access them.

Much of the functional biology encoded in genomes remains hidden in noncoding DNA. In a preprint out today, Patrick Hsu and team introduce COMPASS, a genomic language model-based approach to systematically map this underexplored sequence space.

Do you like riddles(and molecular biology)? Maybe you can help me solve this one. We’ve found a short piece of DNA (a plasmid) present in almost all plague samples from the Second Plague Pandemic (1338-1840), but absent in all earlier or later plague cases. www.biorxiv.org/content/10.6...

A near-ubiquitous plasmid characterises Second Pandemic Yersinia pestis

Yersinia pestis, the causative agent of plague, crippled population across Eurasia in three well-described historical pandemics: The Justinianic plague (541-780), the Second Pandemic (1346-1840) and t...

My final postdoc project is out today in Nature! We show microbes co-migrated with humans out of Africa; three independent methods agree, and timing matches archaeological / genetic evidence (Fig. 4c). Seeing Fig. 4c for 1st time was one of my most memorable "eureka" moments! doi.org/10.1038/s415...

Prehistoric global migration of vanishing gut microbes with humans - Nature

Microbial species disappearing from industrialized populations have evolved with humans over millennia and migrated worldwide with them—this may have consequences for human health.

Andre Geim is the only scientist to win both the Nobel Prize (Physics, 2010) and the Ig Nobel Prize (for levitating a frog in 2000). His secret? He says it was to set up an environment in his lab for doing experiments from a sense of play and a spirit for adventure!
