...obvious place to look for gender differences is in the hypothalamus, a lusty little organ perched over the brain stem that, when sufficiently provoked, consumes a person with rage, thirst, hunger or desire. In animals, a region at the front of the organ controls sexual function and is somewhat larger in males than in females. But its size need not remain constant. Studies of tropical fish by Stanford University neurobiologist Russell Fernald reveal that certain cells in this tiny region of the brain swell markedly in an individual male whenever he comes to dominate a school. Unfortunately for the piscine...
While most cells can be grown in culture, it is often difficult to recreate a reasonable facsimile of the original organ. In the technique, known as autografting, doctors can now remove a group of skin cells one centimeter square from behind a patient's ear, or from a patient's stomach, and within three weeks reproduce a sheet of the cells of whatever size is necessary to treat the patient...
...teeth on. But first the vet had to rule out rat poison and cancer with a blood test ($45) and a liver scan ($140). Then there was the emergency work-up ($45), followed by a catheter ($30), urinalysis ($22), a steroid injection and lab work to check organ function ($71); anesthesia ($345); an IV attached to a leg ($110); a biopsy ($45); upper and lower gastrointestinal endoscopy for fiber-optic images of his stomach, small intestine and colon ($75); antibiotics and Tagamet for the ulcer ($25); plus five days of hospitalization...

We've harnessed the body's natural defenses with antibiotics, defeated plagues and diseases, learned how to make spare parts for almost every organ except the brain...
