A new study suggests humans face barriers to reproducing in space, with microgravity disrupting sperm movement.

The researchers put samples through a simulation mimicking both the female reproductive system and the zero-gravity ...

Human biology evolved for a world of movement, nature, and short bursts of stress—not the constant pressure of modern life. Industrial environments overstimulate our stress systems and erode both ...
