...tracks, and perhaps minimize damage to heart tissue. Says Garrett Lee of the University of California, Davis Medical Center: "Ten years ago, a patient admitted to the hospital would have been taken to the coronary care unit and continued to be monitored. It would be bed rest, oxygen and drugs to prevent such complications as arrhythmias and heart failure-but the heart attack would run its course." With this new technique doctors try to interrupt the attack by feeding a narrow tube through an artery in the groin into the blocked coronary vessel and injecting a drug called Streptokinase, which...
...suddenly, without any obvious hint of previous disease, when coronary arteries pinch shut in a spasm. But they usually result from a lifelong buildup of fatty deposits in the arteries that nourish the heart. If these coronary vessels become badly obstructed, the flow of vital blood and oxygen is reduced or cut off entirely. When that happens, parts of the heart are starved. It is the death of cardiac muscle that constitutes a heart attack...
...they are still perplexed by many dents and chips in the brittle material, especially on the starboard side. Best guess so far: the damage was incurred during lift-off by ice and insulation that broke free of the shuttle's giant external fuel tank, which contained supercold liquid oxygen and hydrogen. Another puzzle is why the bulky, swept-winged "bird" showed greater lift than expected on descent, which carried it half a mile beyond its intended landing spot at Edwards Air Force Base in California. A small glitch was caused by the failure of the shuttle's zero...
...chain, and thereby brought on the extinction of the dinosaurs-an event that profoundly redirected evolution. It is arguable (at least agnostically for a moment) that life itself-the lightning in the sugar cube, the huge fortuities of weather and climate and chemistry, of amino acids and proteins and oxygen-emanates from sheer cosmic luck...
