ISS astronauts lose bone density faster than aging populations, revealing mechanisms of osteoporosis and informing prevention and treatment strategies.

ISS studies reveal how microgravity suppresses immune function, explaining increased infection risk in astronauts and informing immunology treatment strategies.

ISS research reveals how cosmic radiation damages DNA and organisms in space, with findings applicable to cancer prevention, radiation therapy, and long-duration spaceflight safety.

ISS astronauts experience disrupted sleep and circadian rhythms due to 16 sunrises/sunsets daily. Research reveals mechanisms and countermeasures applicable to treating sleep disorders.

Gravity shapes everything about an animal — its skeleton, muscles, circulatory system, even brain. Humans evolved on a 1g planet. On a Mars-like 0.38g world, we'd be taller, lankier, weaker, and likely shorter-lived from chronic bone and circulatory problems.
