The science of living systems. From molecular machinery inside a cell to the dynamics of entire ecosystems, biology explains how life works, how it arose, and how it sustains itself through metabolism, reproduction, and evolution.
The search for extraterrestrial life starts with Earth — not because scientists lack imagination, but because Earth is the only confirmed example of life that exists. Kai Finster explains why using Earth's biochemistry as a template is not anthropocentric bias. It is the only scientifically defensible starting point.
Astrobiology is criticised for being Earth-centric. That criticism misunderstands the epistemics. You cannot search for something you cannot characterise — and Earth is the only example of life we have.
The plant-based movement faces a cultural barrier that engineering cannot solve. Precision fermentation bypasses the debate entirely and will succeed not through moral persuasion but through the same economic logic that ended every previous paradigm shift in food.
A cow converts roughly 4% of its feed into usable protein. Precision fermentation bypasses the animal entirely and produces identical protein in a steel tank. Lars Horsholt Jensen explains why this shift will not happen through consumer choice but through economics.
Danish agriculture produces food with astonishing efficiency — for the wrong target. We have spent a century optimising animal feed production. The next revolution requires recognising when the metric has drifted from the purpose.
