It’s hard to overstate the paradox of cement: it holds up our buildings, our bridges, our entire civilization—yet it also quietly poisons the process. Pound for pound, producing cement releases almost as much CO₂ as the material itself weighs. It’s an unavoidable chemistry problem baked into the modern world.
Until now.
A team of scientists at the University of Washington, working in partnership with Microsoft, has taken an unexpected detour through the ocean—and come back with powdered seaweed as a concrete additive that radically alters the equation.
This isn’t just a quirky material swap. It’s the beginning of a full-blown materials intelligence revolution—where biology meets AI to rewrite what we think infrastructure should be made of.
