Nasa scientists grew corn seeds in space and found that microgravity changed how the seedlings’ roots and shoots grew |
Long before astronauts plant a seed on the Moon or Mars, NASA has been testing a much simpler question here on Earth’s doorstep: What happens when a corn seed germinates without gravity telling it which direction to grow? In the early 1990s, researchers flew dried corn kernels aboard the space shuttle, let them sprout in … Read more
