A colored scanning electron micrograph of human intestinal bacteria that colonize the small-intestine epithelia. Magnúsdóttir et al. (p 81) present a set of 773 semi-automatically generated microbial metabolic models that are fully compatible with the human genome-scale metabolic reconstruction Recon 2. These models could be used to probe the functions of the human gut microbiota. Magnification is ×2,400 when the shortest axis is printed at 25 mm.
