Today in @NatureBiotech we report OptiPrime, a mechanism-based machine learning model for predicting prime editing (PE) efficiencies and suggesting pegRNAs to achieve a user-specified edit. OptiPrime incorporates biochemical knowledge about PE into its mathematical structure, enabling training on ~300,000 PE efficiencies collected using 40 experimental conditions in multiple labs, and outcome predictions of PE variants such as twin prime editing not used in its training. OptiPrime enabled the rapid identification of efficient PE strategies across a variety of applications in vitro and in vivo, and could outperform months or years of manual experimental optimization. Try out OptiPrime here: optipri.me PDF: drive.google.com/file/d/13JZWWI… 1/15

I explore the potential for a new healthcare specialty focusing on people in their 40s and 50s here: fuchsm.substack.com/p/should-we-ha…
At checkups, my doctor asks how often I exercise. I say, "A lot." Next question. Wouldn't a treadmill test showing how I compare with others my age be more useful? Like pediatrics and geriatrics, should we have a new midlife specialty focusing on performance and prevention?

This sentence. 🤌 "Physical activity is a canonical characteristic of humans... the normalization of the lack of physical activity has led to the perception that physical activity is an intervention even though it remains as the modus vivendi engrained in our genes."
Wow. We might be able to identify mitochondrial dysfunction with a simple treadmill test. This new paper by @doctorinigo proposes that two key metrics can serve as a “reliable, early physiological signature of subclinical mitochondrial dysfunction.” • A blood lactate level

Your typical "superager" walks at a fast clip despite the silver hair and wrinkles. But some superagers look and move more like someone in their prime. That's because they're middle-aged. Cynthia McNamee is an example. At 50, she can still sprint at 20 mph. Here's how.
