Researchers injected the mice with samples of fresh and frozen human feces, the bacteria from which took hold and colonized in the gut of the mice. If that surprises you, it absolutely stunned the researchers. "We were surprised that so much of the diversity present in human microbial communities could be recaptured in mice," says Gordon, who has been studying gut microbiota for more than five years...
...fact that the human gut flora flourished in the rodents was indeed an experimental coup. Since the mice were genetically engineered to be germ-free, lacking a functioning immune system, the scientists could be certain that any bug colonies that took hold in the mouse guts originated entirely from the human sample, not the mice. Being able to recreate the living human gut environment so faithfully in an animal was a welcome prize. (Read "The Year in Medicine 2008: From...
...sense of wonder never abated. Describing his first brush with Anglo-American anthropology after a cloistered education at the Sorbonne, Lévi-Strauss wrote that: “My mind escaped from the closed circuit, which was what the practice of academic philosophy amounted to: made free of the open air, it breathed deeply and took on new strength.

Hasan's prescription was dated 2001. At that time, he would have been at the Uniformed Services University of Health Sciences in Bethesda, Md., where he was studying medicine tuition-free, a benefit of his enlistment in the Army. The prescription, as a photograph shows, appears to have been filled by Wilford Hall Medical Center at the U.S. Air Force Base in Lackland, Texas. (See pictures of Nidal Malik Hasan's life...
