Long-distance space travel can wreak havoc on human health. There’s radiation and microgravity to contend with, as well as the psychological toll of isolation and confinement. Research on identical twin astronauts has also revealed a slew of genetic changes that happen when a person spends a year in space.
That’s why some bioethicists are exploring the idea of radical treatments for future astronauts. Once we’ve figured out all the health impacts of space travel, they argue, we should edit the genomes of astronauts ahead of launch to offer them the best protection. Some have even suggested this might result in the creation of an all-new species: Homo spatialis.
If this is starting to sound a bit like sci-fi, that’s because it mostly is, for now. But there are biotechnologies we can use to help space travelers now, too.

MIT Technology Review Narrated: How generative AI could reinvent what it means to play
Open-world video games are inhabited by vast crowds of computer-controlled characters. They make virtual worlds feel lived in and full.
After a while, however, the repetitive chitchat (or threats) of a passing stranger forces you to bump up against the truth: This is just a game.
It may not always be like that. Generative AI is opening the door to entirely new kinds of in-game interactions that are open-ended, creative, and unexpected. Future AI-powered NPCs that don’t rely on a script could make games and virtual worlds deeply immersive.
This is our latest story to be turned into a MIT Technology Review Narrated podcast. In partnership with News Over Audio, we’ll be making a selection of our stories available, each one read by a professional voice actor. You’ll be able to listen to them on the go or download them to listen to offline.
We’re publishing a new story each week on Spotify and Apple Podcasts, including some taken from our most recent print magazine. Just navigate to MIT Technology Review Narrated on either platform, and follow us to get all our new content as it’s released.
