One-Carbon Genetics and SANS: What the Astronaut Data Actually Show—and What IIH Research Does Not Borrow

The clinical puzzle, stated without the sales pitch Spaceflight-associated neuro-ocular syndrome (SANS) is a recognized vision risk in long-duration crews. Idiopathic intracranial hypertension (IIH) is a terrestrial disorder of raised intracranial pressure, typically in young women with obesity, that produces papilledema and can threaten vision. Both involve the optic nerve head, both invite speculation about…

What the ISS Bisphosphonate-and-ARED Experiment Actually Showed—and What It Did Not Prove About Disuse Osteoporosis

The clinical question the flight data can and cannot answer In terrestrial disuse osteoporosis—after spinal cord injury, during prolonged immobilization, or across extended bed rest—clinicians face a practical question: if mechanical loading is already prescribed, does adding an antiresorptive produce meaningful additional protection, or does it mainly suppress a laboratory marker while the skeleton continues…

What the Mighty Mice Experiment Showed About Myostatin Blockade in Microgravity—and What Muscular Dystrophy Drug Development Assumes

Two claims, often blurred Spaceflight biology has a habit of producing headlines that outrun the data. The Mighty Mice investigation—flown to the International Space Station in December 2019—is a useful case study in why that matters for clinical translation. The experiment is genuinely interesting, and the mechanism it probes is real. But the distance between…
