This documented occupational injury isn't caused by launch or landing—it can happen when astronauts spend hours in pressurised gloves during underwater training.
In orbit, astronauts face a calculus unknown to earthbound life: how many times can you wear the same underwear before it becomes a liability roughly 250 miles above the planet.
In September 1940, four teenagers and a dog stumbled into a hole in a hillside near Montignac, in southwestern France, and found themselves standing inside a painted Ice Age cathedral.
A 1970 experiment, published in 1973, staged the Good Samaritan parable in a Princeton alley and analysed what forty seminarians did. Hurry predicted helping. The sermon topic did not reach significance, which was the authors' own prediction and is still not the same as no effect.
Valeri Polyakov spent 437 consecutive days aboard Mir, proving that one highly selected human could remain functional for a Mars-length span while leaving major deep-space risks untested.
When commercial hunters arrived on the Plains, they saw only hides—and erased a civilization built on using every part of an animal.
Mars500 wrist monitors captured less active waking and more sleep and rest across confinement, but the authors' torpor analogy did not mean hibernation and the six men adapted differently.
Two rare male Neanderthal-lineage pelvises fall with modern women on selected mechanical measurements, leading researchers to propose that the modern male pelvis is the later, walking-specialised form.
NASA's best-documented recent selection cycle combined six hours of psychological tests with a long behavioural interview and high-load team simulations, while keeping the exercises themselves confidential.
A Mars crew would leave Earth's magnetic and atmospheric protection for years, turning invisible particle radiation into a mission-wide design problem.
Wearable sensors at Concordia Station found that more close-range contact tracked more conflict and mistrust, but the one-crew study measured proximity rather than interaction quality.
A phantom sound that tormented Bristol residents in the seventies has resurfaced worldwide, suggesting something science still cannot explain.
The algorithm knows your symptom is probably nothing—but it's going to convince you otherwise anyway.
The brain never forgets gravity—it's the body's predictions that need recalibrating after months in orbit.
Loneliness and social isolation are not the same thing. Research suggests that the quality of relationships can matter alongside the number of people in someone's life.
The 45% figure is a modelled population-level estimate, not proof that the factors caused each case or that the remaining dementia burden is fixed.
