Soil on a chip (IMAGE) Princeton University, Engineering School Caption Soil on a chip experiments conducted by Princeton researchers mimic the interactions between soils, carbon compounds and soil bacteria, producing new evidence that large carbon molecules can potentially escape the soil much faster than previously thought. In this microscopy image, soil bacteria (red) grow around aggregates of glucose (green) that stick to pores in a transparent synthetic clay. Credit Judy Q.
