Spotted this story on Yahoo News: Scientists say a rock can soak up carbon dioxide.

It had this picture, with the caption:

Scientists sample a stalagmite of carbonate minerals in an undated photo courtesy of Columbia University’s Lamont -Doherty Earth Observatory. A rock found mostly in Oman can be harnessed to soak up the main greenhouse gas carbon dioxide at a rate that could help slow global warming, scientists say.

Looks like a totally fun job to have.
