This appears to be supported by the findings of a 2022 paper, in which scientists describe the results of taking C. sphaerospermum into space and strapping it to the exterior of the ISS, exposing it to the full brunt of cosmic radiation.
There, sensors placed beneath the petri dish showed that a smaller amount of radiation penetrated through the fungi than through an agar-only control.
The aim of that paper was not to demonstrate or investigate radiosynthesis, but to explore the fungus’s potential as a radiation shield for space missions, which is a cool idea. But, as of that paper, we still don’t know what the fungus is actually doing.
That’s where it seems really cool to me. If we have nuclear spacecraft or even just passive cosmic radiation exposure, what’s otherwise a waste/threat could become a factory. Reinforcing the hull with a regenerative radiation shield, genetically engineering it like E. coli to biosynthesise needed compounds, mass producing it as food for something we can eat- it’d be so useful to have something like that in space where you’re surrounded by energy you can’t use.








Thankfully it hasn’t made it into my workplace yet. We have a quarterly newsletter that someone tried to submit ChatGPT slop to. It was immediately identified and rejected by the rest of the horticulturists. My bosses are the kind of people who only talk about plants in Latin so there’s a big institutional focus on getting the right information from primary sources and then using multiple layers of expert review.
However, we’re facing massive budget shortfalls over the next few years and I doubt that will get any better if the economy crashes. Outside of installing/maintaining plants, the bulk of the job is intellectual and creative labour that the public isn’t even aware of. I can absolutely see my workplace hollowing out the job and not hiring based on expertise. Instead of five people with scientific degrees debating a space for an hour, at some point it’s going to be someone who hasn’t seen that space feeding words they can’t pronounce into an LLM that doesn’t understand what space is. On paper it will look great for the metrics admins and other departments track. In practice it will immediately ratfuck everything that makes our urban forest function and drive away the really rare pool of overqualified people we have.
