3. Bacterial Biofilms in Orbit

Summary: Certain bacteria formed stronger protective biofilms when cultured in microgravity.

Bone Density Loss in Astronauts

Summary: Spaceflight reduced bone mineral density, similar to accelerated osteoporosis on Earth

Muscle Atrophy in Zero Gravity

Summary: Astronaut leg muscles showed up to 20% shrinkage after 6 months in space

Seed Germination in Space

Summary: Seeds germinated normally, but early root orientation was random in microgravity conditions.

Microbes and Antibiotic Resistance

Summary: E. coli exposed to spaceflight showed higher antibiotic resistance than Earth-grown samples.

Regeneration in Flatworms

Summary: Flatworms cut in space regenerated differently, sometimes forming two heads.

Spaceflight Effects on Heart Cells

Summary: Human heart cells grown in space showed irregular beating patterns.

Radiation Impact on DNA

Summary: Space radiation caused double-strand DNA breaks, but certain repair pathways were more active.
