...Crocodile Hunter down your throats, we deserve it. But I really can't find it in my heart to excuse CBS for Episode 2's immunity challenge, in which the contestants must eat "true Aboriginal food, what they call bush tucker."

The problem was, it failed to kill every single bug, and those that survived the onslaught slowly began to multiply. The result: by the 1950s most staph infections had become highly resistant to penicillin. The same fate met penicillin's successors, erythromycin and methicillin; now it appears to be vancomycin's turn...
...those checks is the T cell's dependence on another cellular player: the antigen-presenting cell. The APC is an omnivorous creature whose job, among other things, is to gobble up microbial invaders. To initiate the immune response, the APC coughs up a molecule from the bug it has eaten, latches on to a helper T cell and "presents" it with a target molecule, instructing the T cell to prepare its troops for war. This activation is tightly controlled; it cannot occur without the lockstep interaction of several proteins on both cells--one of which is known...
...soon-to-explode planet early. By 1999, Pat Robertson was selling tickets to seminars where people were taught how to store beans and corn in separate barrels sealed with nitrogen packs. He apparently figured God had traded in fire and brimstone for the more subtle New Year's computer bug...
