  • In this atomic force microscope image, the rings of light-harvesting complex 2 (LH2) are seen on the surface membrane of a purple bacterium. The arrangement of these complexes, as well as their shapes, help to make them extremely efficient at collecting the energy from light.
  • To determine the location of ALKBH7 in cells, MIT researchers engineered these cells to express ALKBH7 bound to green fluorescent protein (GFP). The cells’ mitochondria express a red fluorescent protein. In cells where ALKBH7 is present in the mitochondria, the green and red signals mix and appear yellow.
