It’s extremely unlikely. Of the trillions of species on Earth, only a handful are harmful to humans, and fewer still are deadly. These bacterium would have to mutate an enormous amount to have any interest in humans, for one, and even more to be virulent.

This could be a great thing to use on paths etc instead of normal concrete and it would certainly fix cracks a lot quicker. As if cracks appear in regular concrete then a Concrete repair company needs to be called out. This is were this money and time can be saved.

This new concrete that repairs itself is definitely something that I would recommend.

Looking at the challenges of our infrastructure – self sealing (not so much healing) concrete would be a boon. Cracks permit water to penetrate concrete, water in contact with reinforcing steel causes rust, rust takes up 7 times the volume of steel and causes concrete to crack more and spall, exposing more steel to water… see where this is going?

If the cracks in concrete could be effectively sealed from the outset, the maintenance cycle for our roads, bridges, dams and buildings could be greatly extended. Hoping they can solve the survivability issue and get this out of the lab.

@7. – This is a different take on biophyllic design in engineering and architecture.
@11. – Brilliant comparison – this is the next best thing to sliced bread in my books.

Self-healing concrete : civilization = sliced bread : sandwiches.

For a second I thought it said ‘self-hating concrete’ and wondered why it would bother repairing itself.
