I repeat- I haven’t been this excited about a discovery since CRISPR. We found something enigmatic that, like CRISPR, is associated with microbial genomes. We have named these unique entities #BORGs
^This tweet was written by Jillian Banfield as she describes the latest preprint coming from her research lab on the discovery of BORGs, giant extrachromosomal elements that may uncover new biology to mitigate climate change and methane levels, but also provide new gene editing tools.

![the 3 levels of aging therapeutics
Why do so many anti-aging drugs work in mice but fail in humans? It turns out, we might be aging in fundamentally different ways. A new minimal model from physicists Peter Fedichev and Jan Gruber suggests that aging isnt a chaotic mess of billions of problems, but a process governed by just three macroscopic variables.
In this video, I break down their paper to explain why current Level 1 interventions (like senolytics and cellular reprogramming) might only improve healthspan, not maximum lifespan. Well explore the difference between stable species (humans) and unstable ones (mice), and reveal the physics-based roadmap—Level 2 and Level 3—required to actually extend the human lifespan limit beyond 120 years.
