The stories behind the science
Long-form articles that go beyond the modules — the history, the controversies, the unsolved problems, and the ideas that keep biologists up at night.
How CRISPR Actually Works
Not the simplified version. The real molecular machinery — how a bacterial immune system became the most powerful editing tool in the history of biology, and what it can and can't do. From the discovery of repeat sequences in 1987 to the Nobel Prize in 2020 to the first approved therapy in 2023.
Why We Age — The Biology of Aging
Aging is not programmed obsolescence. It's the accumulated cost of staying alive. Telomere erosion, senescent cells, mitochondrial decay, epigenetic drift — the molecular mechanisms of aging and why some researchers now think it can be treated.
The Real Story of DNA's Discovery
The textbook version credits Watson and Crick. The full story is messier, more human, and more interesting — involving X-ray crystallography, a stolen photograph, a brilliant woman whose contribution went unacknowledged for decades, and a race that shaped modern biology.
How Consciousness Might Emerge From Neurons
The hard problem of consciousness is the deepest unsolved question in science. What do we actually know, what do we theorize, and why is explaining subjective experience so fundamentally different from explaining everything else biology has tackled?
The Ecosystem Inside You
38 trillion microbial cells. 20 million microbial genes. A gut-brain axis that influences mood, behavior, and disease. The human microbiome is not a passenger — it's a co-evolved organ we're only beginning to understand.
Cancer as Evolution
Cancer is not a disease in the traditional sense — it's evolution happening in the wrong place. Understanding why tumors are so hard to kill requires understanding them as ecosystems under selection pressure. And that reframing is changing how we treat them.
The Origin of Life — What We Actually Know
Abiogenesis is the biggest unsolved problem in biology. Not because we have no ideas — we have several compelling ones. The challenge is knowing which actually happened. A deep look at the RNA World, hydrothermal vents, meteorites, and the chemistry of life's beginning.
The Sixth Mass Extinction — What's Being Lost
We are living through a mass extinction event in real time. Not a prediction — an observation. What's being lost, how fast, why it matters beyond the obvious, and what the biology of extinction crisis actually looks like at the population and ecosystem level.
