After the world's first "living robot" was revealed recently, "living concrete", which is leading the future of architecture, has been unveiled.

Developed by scientists at the University of Colorado Boulder, this "living concrete" is made from a mixture of sand, gel and bacteria that can grow and repair itself, and the material can significantly reduce its carbon footprint.

Concrete is one of the most used building materials in the world, but no matter how to strengthen this material, all the concrete will eventually crack, long-term neglect can even lead to the collapse of buildings, so professionals have long been looking for a more reliable material.

In addition, the production of cement -- the cementing material used to make concrete -- accounts for 6 percent of carbon dioxide emissions, which are released when concrete is solidified, which is not good for the environment.

The new "living concrete" makes up for the shortcomings of traditional concrete.

The new material contains a bacteria called cyanobacteria that is 3.5 billion years old.Cyanobacteria reproduce asexually and can form dormant resting spores under dry, low temperature and prolonged darkness, which can continue to grow under suitable conditions. 

Scientists later demonstrated the bacteria's properties in experiments.They put sand, hydrogels containing water and nutrients, and cyanobacteria in a container and found that the microbes could absorb carbon dioxide from the air to form calcium carbonate, the main ingredient in cement.This will be able to sand, stone and other materials together.

Later, scientists also split the bricks in half and found that with the help of excess sand, hydrogels and nutrients, they grew into two whole bricks.And a mother brick can produce up to eight bricks after three "reproductions".

The study is in the journal Matter.
