So, not repair itself.

Is there an adjective for something that's nifty but also gross?

How does it smell though?

The claim in the article that saccharomyces cerevisiae (brewer's yeast) naturally produced the deep blue color in the butterfly example is not actually true, although it's a gorgeous effect.

These are genetically engineered variants of brewer's yeast designed to produce pigments.

I wonder if there is a health hazard wearing this due to breathing in spores or toxins released into the air? Or perhaps there is a risk that the wearer will absorb harmful chemicals secreted by the mycelium via contact with the wearer's skin? Very interesting none the less. I have imagined humans making living clothes for a long time, so it is nice to see that idea materialize.

Could they make a house out of this?

I would buy one, but I don’t think I have mushroom in my wardrobe for it.

Is there a possibility of the organisms escaping the material and infesting the environment? That's what I would worry about with mycelium.
