Experimental concrete that patches up cracks by itself is to undergo outdoor testing.
The concrete contains limestone-producing bacteria, which are activated by corrosive rainwater working its way into the structure.
The new material could potentially increase the service life of the concrete - with considerable cost savings as a result.
The work is taking place at Delft Technical University, the Netherlands.
It is the brainchild of microbiologist Henk Jonkers and concrete technologist Eric Schlangen.

2. Is there anything that bacteria cannot do?
I've listened to every Skeptics Guide to the Universe podcast. On their weekly game Science or Fiction, the quirky and amazing things that bacteria can do comes up regularly. I am never surprised when the bacteria items end up being science.
Here's another amazing bacteria fact:
