Final clubs were surely more "cohesive" in a certain sense back when they admitted only the Andover-bred scions of wealthy white families, but it was a lazy cohesion sustained by uniformity, and few express a desire to return to those days...
...fatter mice in Gewirtz's study had been bred to lack a protein known as toll-like receptor 5 (TLR5), which most intestinal cells sprout on their surface. Its job is to recognize and bind to the whiplike flagella that bacteria use to move around. TLR5 acts as a traffic cop for controlling the mass of pathogens living in the intestine; without it, the normally harmless gut bacteria tend to overflourish and expand in number. (See and listen to an audio slideshow about obesity rehab...
...finding was confirmed when the team transferred the bacterial gut population from TLR5-deficient mice into animals that were specially bred to have no immune system, making them incapable of rejecting foreign cells and bacteria. When these animals received the teeming gut world of the TLR5-deficient mice, they too began eating more and developed the same metabolic-syndrome symptoms that their donors had. In other words, the obesity profile of the heavier mice had been transferred to normal mice. "So, applying the logic to humans," says Gewirtz, "we know that to gain weight and become obese, [it] requires...
...this hybridization "because it's already been done and they have no other cards to play." It could be up to 10 years before the first pregnant tigers are taken to a remote, enclosed area within the reserve to deliver the cubs that will eventually populate it. Although captive-bred, the mothers will teach their young how to hunt and kill prey. "This ability is hardwired," says Tilson. "They don't lose...
