UK students create 3D-printed coral structures that could rebuild world’s damaged reefs
Students at the University of Exeter have developed an environmentally friendly technique that could help to rebuild coral reefs.The project, called CalcifEXE, uses genetically modified bacteria to make calcium carbonate, which can then be shaped into coral "backbones" using a 3D printer. The scientists hope they can then attach live coral to the backbones, before placing them in the ocean to grow new reefs."It will be lovely to think that it's going to become a new weapon in the fight against climate change," Dr Mark Hewlett, the students' supervisor, told Sky News.
