It’s easy to imagine a future where humans travel freely through space, visiting places like the Moon and Mars to carry out research or perhaps even set up colonies. There are many technological hurdles to scale before such a future is even remotely possible, but what about the biological impacts on our own bodies? Scientists aimed to answer some of those questions, and a new paper published in Radiology reveals one very interesting effect of long-term spaceflight: Human brains get physically bigger.
The research has led to some very important questions about how well-suited humans are for space travel, and what kind of long-term effects travelers to the Moon, Mars, and beyond, may experience.
