Summary:

- The article discusses the development of a new type of concrete that can absorb carbon dioxide from the air and turn it into a solid material.
- This "CO2-absorbing" concrete was created by researchers at the University of Cambridge and could potentially help reduce the carbon footprint of the construction industry, which is a major contributor to global greenhouse gas emissions.
- The concrete works by using a chemical process to convert the CO2 into a solid mineral that becomes part of the concrete, effectively locking the carbon away and preventing it from being released into the atmosphere.
