New bacteria developed that can fill cracks in concrete

Concrete eventually cracks. It just happens! But filling cracks in concrete can be a tedious process, and it's not generally at the top of most maintenance lists. But a new bacteria could fill concrete cracks with little work required.

Developed by a group of students at Newcastle University in the UK, BacillaFilla produces a mixture of calcium carbonate and a "bacterial glue" that combine with bacterial cells to fill in cracks snugly.

Currently, BacillaFilla have a "kill switch" that keep them from working outside of the lab until they can make sure these things won't turn just anything into concrete. Which seems like a good idea. Nobody wants to catch a bacteria that makes them turn into concrete unless it also turns them into a superhero.
