Spaceflight Weakens Our Weight-Bearing Bones the Most

As humans continue to make tentative progress out into the cosmos, the impact of space exploration on our fragile bodies is only beginning to be understood. We know that space travel decreases muscle and bone mass but a team of researchers have discovered which bones suffer the most! Using a group of mice that became astro-rodents for 37 days, they discovered that bone degeneration effective the femur most but not the vertebrae. They concluded that it’s our weight-bearing bones that suffer the most.
