A 1940s math theorem may explain how plants know which way is down
Why This Matters
Inside plant cells, tiny starch granules tumble in response to gravity — but how accurately can a handful of microscopic beads tell a plant which direction to grow? It turns out a statistical theorem invented to optimize radar detection during World War II could set a hard mathematical ceiling on that precision, and plants may have evolved to hit it almost perfectly. If confirmed, this connection could give scientists an exact formula for engineering crops that spring back upright faster after storms — by revealing, for the first time, exactly which parts of the gravity-sensing system are worth improving and which are already as good as physics allows.
