Drivers the over may soon have from potholes and cracks in the road. Scientists from the universities of Bath, Cambridge and Cardiff have come up with a and innovative solution to plugging and holes in roads and highways. They have created a bacteria-filled concrete to prevent cracks in a road from becoming . The concrete is full of bacteria that open when seeps into a crack. The bacteria burst open and inject limestone into the crack, thus filling and repairing it to avert more damage. The scientists believe their could considerably increase the of roads, reduce repairs, and lower roadwork by up to 50 per cent.

The new concrete could be good for the environment. Scientists estimate that over seven per cent of the world's CO2 come from the production of cement.
