...Nussenzweig of N.Y.U. continued to pursue a malaria vaccine, a goal many viewed as impossible. The malaria bug presented unique obstacles. The first was the complex life cycle of the Plasmodium parasite, which is in a sense three bugs in one (see diagram): the sporozoite, which enters the human bloodstream when an infected mosquito bites; the merozoite, which invades the red blood cells and causes the disease's chills and fever; and the gametocyte, which, when ingested by a biting mosquito, reproduces inside the insect and yields a new generation of sporozoites...
This year began with the announcement by the Federal Government of the results of the broadest and most expensive research project in medical history. Its subject was cholesterol, the vital yet dangerous yellowish substance whose level in the bloodstream is directly affected by the richness of the diet. Anybody who takes the results seriously may never be able to look at an egg or a steak the same way again. For what the study found, after ten years of research costing $150 million, promises to have a profound impact on how Americans eat and watch their health. Among the conclusions...
...Does landscape enter the bloodstream with the milk?" The poser of this oddly shaped question, Ronald Blythe, is author of a classic documentary on English village life (Akenfield), and he permits no doubt about the answer. In this celebration of social roots, Blythe contrasts what he sees as the skittering superficiality of jet-age tourists with the intense thereness of stay-putters like the 19th century poet John Clare, who went mad when he had to leave the village where he was born.

...blood samples are used to determine how much the insulin reaches bloodstream over a given time period. Another drug, Adjuvent, is sprayed on the nasal membranes to enhance the absorption of the insulin...
Free-basers are apparently the likeliest to die. The high is more intense than the high from snorting (and equal to that from injection) because the pure, heated cocaine vapor is absorbed into the bloodstream so fast. The speed of absorption, not the size of the dose, also seems to be the operative factor in cocaine deaths. Blood vessels are simultaneously constricted and cardiopulmonary muscles overstimulated; heart attacks (sometimes not diagnosed as cocaine-triggered) or lung failure are the direct causes of death...
