Agnirva Space Premier League - Expedition #30319: The Skeleton’s Digital Twin: Unlocking Bone Mysteries in Space

The complexity of bone biology goes far beyond simple calcium loss. The experiment "Unsolved Issues for the Skeleton and Role of FGF23-Klotho Axis—Contribution of a Bone Digital Twin" dives deep into understanding the regulatory systems that govern bone health, especially under the strain of spaceflight.

One focus is the FGF23-Klotho axis—a hormonal signaling pathway that controls phosphate balance and bone metabolism. In space, where bones lose mass rapidly, understanding how this axis behaves can provide clues to preventing bone degradation.

Scientists developed a "bone digital twin"—a sophisticated computer model replicating bone structure, function, and response to stress. By feeding the model with data from real astronauts, researchers could simulate various conditions and predict outcomes.

This interdisciplinary effort, involving multiple European and international agencies, represents a fusion of biology, engineering, and data science. It aims to identify which molecular triggers affect bone remodeling in microgravity and to test potential countermeasures without risking human health.

Insights from this experiment could transform osteoporosis treatments and advance personalized medicine. By modeling individual responses, therapies can be tailored to specific needs, both in space and on Earth.

Ultimately, this digital twin approach allows for safer, faster innovation in both astronaut care and terrestrial health challenges.
