Blue glowing, spherical structures float in front of a dark, blurred background in the room.

Using light to break down and bind CO2: two new research groups want to make what nature already does much more efficient more

Illustration of a pair of twins. In front of each twin is a circle with a drawing of bacteria, a representation of a brain, and a mouse. The person on the right looks happy, the bacteria are bluish, and the mouse is running with its eyes open. The person on the left looks unhappy, the bacteria are more pink in color. There are pink spots in the brain, and the mouse is lying down with its eyes closed.
