Sea urchin nickel 'trick' could be key to capturing carbon

Researchers say that the natural ability of sea urchins to absorb CO2 could be a model for an effective carbon capture and storage system.

Newcastle University scientists discovered by chance that urchins use the metal nickel to turn carbon dioxide into shell.

They say the technique can be harnessed to turn emissions from power plants into the harmless calcium carbonate.
