Gut Bouquet

This Valentine’s day, everything is coming up roses -- even our guts. This cellular bouquet, composed by research associate Chong Li Yen at Duke-NUS in Singapore, is in fact a slice of human colon tissue viewed under a microscope. The tissue is cut to reveal the cross-sections of intestinal glands, tiny wells in the gut wall that absorb water and nutrients while oozing mucus and digestive enzymes.
