A Cure for Cracks in Concrete

The microbe, created by a team of researchers at the Newcastle University, has been programmed to swim down fine cracks in the concrete.  Once at the bottom,  it produces a mixture of calcium carbonate and a bacterial cells to “knit” the building back together, the researchers said. It as been aptly named as “BacillaFilla” It has been developed to prolong the life of structures which are environmentally costly to build, said the researchers who designed it as part of a science competition in the US.
