Long-form analysis at the intersection of AI and life sciences — all spells, sorted by time.
# Your Cell's Battery Just Got Replaced: Scientists Actually Did It > **TL;DR**: When your phone battery dies, you swap it out. In 2026, scientists did the sam

Andrej Karpathy stopped writing code by hand in 2024. Not from burnout — from evolution. His framework for AI-orchestrated development is the clearest preview we have of what software engineering becomes next.
Autophagy is your cell's recycling crew. But past a critical damage threshold, it switches allegiance — protecting senescent cells instead of clearing them. A 2026 review proposes a threshold model and maps exactly where the betrayal happens.
Iron is essential. Under the wrong conditions it ignites a molecular chain reaction inside your cells that looks exactly like rust. Scientists only named this process — ferroptosis — in 2012. It may be one of the central engines of aging.
> TL;DR: You produce over 200 billion blood cells every day. But the stem cells responsible for that production are slowly going on strike. A wave of landma
