"Hypergravity" Rewires Biology Over the Long Haul

There’s a specific sequence in the anime Dragonball Z that for some reason has stuck in my head for over two decades. Goku, the main character of the show, travels to King Kai’s planet and can barely stand up when he arrives because the planet’s gravity is 10 times stronger than Earth’s. Over time, he trains in this gravity, and his body begins to adapt to it. Eventually, after leaving the planet, he’s stronger, faster, and more agile than he ever was before. But would that really happen if you were exposed to 10G over a long period of time? Researchers at the University of California Riverside (UCR) decided to test that idea and report their results in a recent paper in the Journal of Experimental Biology. But instead of using anime characters, they used fruit flies as their test subjects.
