Because her photos capture their subjects at work, Litwack called them "environmental portraits." She said she interviews each woman twice to develop an appropriate setting...
...abnormality known as SCID (for severe combined immunodeficiency), these mice usually die at an early age, often of pneumocystis pneumonia, the disease that kills many AIDS patients. The researchers implanted some 300 of the defective mice with tissue taken from human fetal thymus, where certain immune and blood cells develop, and with blood-forming cells from fetal liver. The implanted tissues soon produced mature human T cells, specialized white blood cells that help provide immunity against disease. Mice that additionally received fetal lymph tissue -- needed for the functioning of some immune cells -- also developed mature human B cells. All fetal...
There was yet another unexpected consequence of the experiment. After being injected with human immune cells, many of the mice suddenly developed rapidly growing cancers, perhaps caused by a virus in the blood of some of the donors; mice injected with cells not exposed to this virus did not develop the tumors. The implications for cancer research could be enormous: the rapid growth -- in eight to 16 weeks -- would afford scientists a rare opportunity to track the emergence and spread of cancer. Said Mosier: "This is an extraordinary breakthrough. We may be able to dissect that tissue week by week...
...nine leading computer companies -- among them Tandy, Compaq and Hewlett-Packard -- gathered in a Times Square hotel ballroom to declare their independence. The computer makers, who collectively sold 50% more personal machines last year than IBM did, plan to join ranks with 55 other manufacturers and suppliers to develop their own standards for the equipment's inner workings. By creating their new system, dubbed Extended Industry Standard Architecture, the renegades are betting that the $39 billion personal-computer business has grown large enough to support yet another distinct standard, in addition to IBM's and Apple...
