...enormous aerial camera from World War II to photograph the region between the sun and Mercury....Mauritania has one modern hospital. Six doctors. Four midwives. Fifty-eight secondary school teachers.

Theatricality has been in Wyeth's marrow since childhood, and his paintings, when weak, rarely permit one to forget the atmosphere of lantern-lit masquerade in which his father, the profusely talented illustrator N.C. Wyeth, reveled. When swashbuckling or fantasticated, as in much of his work before the 1960s, that theatricality could make Wyeth seem as vulgar as Thomas Hart Benton-though much subtler in design and drawing...

But there was considerable speculation that his flabbiness and frailty were really due to radioactive cobalt treatments for a disease thought to be cancer of the bone marrow. Lending some credence to this rumor is the fact that one of his physicians, Professor Jean Bernard, is a leading leukemia specialist...
Luckily, the infant had four sisters; one of them had cells similar to his. Using a local anesthetic, Good's team inserted a needle into the bone of the sister's leg and withdrew about a billion marrow cells. Then, they injected the cells into David's peritoneal cavity, relying on the cells' natural homing instincts to guide them to the bone marrow. The graft took. Graft-v.-host reaction set in, peaked and finally passed. The new cells overcame David's lethal legacy by giving him the immune system he lacked; the child, now five, is immunologically normal...
...quickly recognize, attack and destroy any foreign matter that enters the body. The system is complex and depends for its function on a wide variety of highly specialized substances. Its main agents are cells called lymphocytes, which are produced by the so-called "stem cells" of the bone marrow, the mushy, reddish substance that manufactures blood components. Once formed, the lymphocytes develop into two distinct types of cells, each of which plays an important role in the immune response. Those that pass through the thymus-a small organ located just under the breastbone in children (it shrinks and virtually disappears...
