I regarded Kalpita across my desk during our interview as she explained how she was fascinated by mitochondria and was really excited about my lab’s research.
The 13-day accumulation rate you've observed and identified creates instability in our understanding of the genome Martin, in both senses of the word 😆.
If we adopt a bioenergetic-first framework, akin to the nuclear transfer experiments highlighted by Dr. Thomas Seyfried, it suggests that the nuclear genome is not a static blueprint, but a dynamic 'sink' for mitochondrial interaction.
• In this light, post-mitotic neurons may carry a permanent biographical record of metabolic stress via somatic Numtogenesis.
Your article made me think: What if the genes governing synaptic plasticity are more susceptible to these Numt insertions because they are physically accessible during high-energy demand?
• If so we may be looking at the primary driver of E/I circuit imbalance in the aging brain.
Following your MitoBrainMap, does the 'Numt-burden' correlate with the specific bioenergetic thresholds of different cell types?
• It would be fascinating to determine if a cell's genomic decay is effectively a 'secondary' event, a failure of the mitochondria's energy coherence.
The broader implication is perhaps quite stark:
Have we spent decades mapping the 'Epigenome' while overlooking a stochastic, cumulative 'Numt-ome' that is actively rewriting the cellular code in response to a life lived under metabolic insult?
Whenever energy flows, it leaves traces. The epigenome can be understood as a set of malleable traces, leaving genes more likely or not to be expressed. Agreed, Numts appear to be a yet more stable way in which energy flow leaves traces. Whether specific cell types in different states accumulate Numts more than others remains to be seen. Good hypothesis.
Thanks Martin, appreciate that I may be on the right track. Might try exploring this avenue myself and see how it goes, might even write a blog about it!
Looking forward to your journey with energy, and perhaps we may collaborate in the future, who knows?
As someone who has spent their education looking at neurodegenerative diseases so far, these questions keep me thinking how we can tackle the huge financial burden Alzheimer's and Parkinson's and other dementias cause on society?
Perhaps, figuring out how we lose energy as age and combating that loss is where the answer lies.
This was one of those “behind the paper” pieces that reminds me why good science is always a human story first. What stayed with me is the audacity of the question: we talk about the genome like a fixed blueprint, but your path into brain mitochondrial DNA insertions makes the whole thing feel more like a living document, constantly negotiating with stress, time, and cellular energy demands. That’s a paradigm shift in tone, not just a finding.
I also appreciated how you showed the texture of discovery: the initial “this can’t be real,” the methodological paranoia (as it should be), the slow accumulation of converging evidence, and then the moment where the data stops being an artifact and starts being biology. That arc is so important for readers to see, because it’s the antidote to both scientific cynicism (“it’s all noise”) and scientific naïveté (“one paper proves everything”).
And the mortality link, even as a signal rather than a conclusion, lands with gravity. Not in a doom way, more in the “we should be paying attention to mitochondria as information, not just as fuel” way. It makes the idea of aging feel less like a vague downhill slope and more like a set of measurable, mechanistic processes that connect life experience to cellular outcomes.
Thank you for writing it like this! Clear enough for non-specialists, but honest about uncertainty and the work it takes to earn a claim.
“Whenever energy flows, it leaves traces,” said Martin. And where does energy flow? Wherever we think, speak, act. Therefore, what we do, leaves traces, it changes our genome, in other words. Please correct me where I am wrong.

Would love to hear your thoughts on this Martin.
Great questions, Rohit.

Yes, this is what struck me as well. The humanity of this scientific discovery still was tangible amidst the science.
Humans are storytellers at our core, telling stories for millennia.
The most audacious questions need the courage and the ability to withstand being perceived as stupid.
Maybe that's why people do not ask the obvious questions.
What do you say?
