Not obviously worth the effort(though the growth patterns might make tracing easier). These fungi are unusual in that they can make use of the energy added by a gamma ray strike, rather than just suffering damage like a normal organism; but they don’t ‘de-irradiate’ things any more than other life forms, or sand, or dirt, or a new layer of paint. The radioactive sources remain and continue to emit for whatever period physics prescribes. These little guys just make good use of the gamma rays they absorb, rather than ignoring them(as a layer of dead shielding material would) or suffering harm, as most organisms do.

The more we learn about life, the more we learn that it can survive almost everywhere. If life preceded us, it would already be everywhere.

I suppose we can do a few more checks on Mars, Venus and Europa to see if life is already there. But, then it’s time to get down to work. If we want an interesting, living universe, we need to spread life. We already have templates that we can use to infect the Solar System.

The iPad should be all the evidence we need to demonstrate that we are genetically disposed to creating bigger and better monoliths.

They briefly note that plants are already getting energy from light. Light is just another wavelength of electromagnetic radiation so maybe this fungus getting energy from radiation(!) radiation is not so far out.  Maybe we should say that plants have the superpower too.

Is there a Photosynthesis Man in the comic book universe?

And wouldn’t you know it? I’m allergic to the damn thing.
