We're no longer asking whether mRNA works. We're refining it. New in Nature: ac4C, an mRNA modification that boosts protein yield AND accuracy, reducing translational errors. This is what a maturing platform looks like—precision, molecule by molecule. 🔗 www.nature.com/articles/s41...

N4-Acetylcytidine enhances synthetic mRNA translation yield and fidelity - Nature

Different RNA modifications elicit different translation elongation rates for in vitro transcribed mRNAs that result in disparate translation outputs and fidelity, as shown here for N4-acetylcytidine ...

Ten months ago I had never written an op-ed. I believed the work spoke for itself. It doesn't. When the government calls a lifesaving technology unsafe and scientists stay silent, the silence becomes the story. A new @jhu.edu profile on why I stopped staying quiet: hub.jhu.edu/2026/06/24/j...

A staunch voice in support of science

Jeff Coller, a pioneering RNA biologist, has spent the past year vehemently advocating for the lifesaving promise of research in the face of federal cuts

In Opinion The system that turned Gila monster venom into GLP-1 drugs is being dismantled through research budget cuts, Jeff Coller writes in a guest essay. “Less support for scientists means strange questions no one will get to chase. Exploring those questions is how medicine advances.”

Opinion | We Need to Keep Funding Weird Science

Science turned a serendipitous finding about lizard venom into one of the most important drugs of the century, but that type of research is getting harder to do.

Halting mRNA vaccine development in the US has broader implications beyond infectious diseases, impeding innovative cancer and rare disease treatments. Science is interconnected; each step forward contributes to collective knowledge and new breakthroughs. www.sciencenews.org/article/mrna...

mRNA vaccines hold promise for many diseases. Now the tech is under fire

Researchers warn that halting federal contracts for mRNA vaccine research could weaken pandemic preparedness and slow medical advances.

Recent policy changes are putting American biotechnology leadership at risk while potentially restricting access to new treatments. It's time to refocus this debate & prioritize innovation over political rhetoric. Please read my discussion in today's Wall Street Journal. apple.news/AEckHTX4qTKW...

Opinion | RFK Jr.’s Dangerous Attack on mRNA Research — The Wall Street Journal

Covid-era coercion and misinformation bred public distrust, but the vaccines did save countless lives.

This decision risks ceding America's competitive advantage in biotechnology to other nations expanding their investments in mRNA research. American patients may increasingly depend on foreign innovation for breakthrough treatments. www.statnews.com/2025/08/05/m... via @statnews.com

Health secretary RFK Jr. shuts door on U.S. investment in mRNA vaccine research

Vaccine experts and people steeped in pandemic preparedness expressed horror at the news that RFK Jr. has shut the door in U.S. investment in mRNA vaccine research.

In a new @nature.com e article, BDP @jmcoller.bsky.social talks about mRNA’s potential not just in thwarting infectious threats but also in treating many of the same chronic conditions targeted by RFK Jr’s ‘Make America Healthy Again’ initiative. www.nature.com/articles/d41...

How political attacks could crush the mRNA vaccine revolution

Drug makers are scrambling to navigate an ‘existential threat’ to a once-celebrated technology.
