Unlike an internal combustion engine, which burns its fuel so inefficiently that only 20 percent of the energy in gasoline gets used, a fuel cell can pull off at least 30 percent efficiency by reacting its special fuels--hydrogen and oxygen gas--electrochemically...
...similar process produced the even deadlier toxin of botulinum bacteria, but because oxygen kills these germs, they were grown in a fermenter infused with nitrogen. Botulism is a severe kind of food poisoning that causes paralysis and death. The Iraqis also used the castor-bean plant, widely grown in the country, to produce the poison ricin, which kills by altering the body's use of proteins and causing circulatory collapse and heart failure...
...good cholesterol" you hope will turn up in your blood test has that name for a reason. More properly known as high-density lipoprotein (HDL), it can prevent the damage done by its evil twin, low-density lipoprotein (LDL). The latter clogs blood vessels by combining with oxygen to form a substance that sets off alarms in the immune system. White blood cells rush to attack it, and the whole mess forms into sticky globs called plaques that cling to vessel walls like mineral deposits in a water pipe. When these deposits break off and blood clots around them...
...good because it keeps LDL from combining with oxygen in the first place. But doctors at UCLA studying HDL in mice have found that when the immune system is under stress--after surgery, for example, or during a major infection--HDL stops producing an enzyme called paraoxynase and thus loses its antioxidant properties. When good cholesterol goes bad, moreover, it goes really bad. Not only does it stop protecting the body against LDL, but it also seems to goad the immune system into forming plaques even more quickly...
...above 70,000 feet. Its cruising speed is a relatively slow 430 m.p.h., which can make it vulnerable (seven have been shot down), and its range is more than 4,000 miles. Dress code for pilots: a full-pressure astronaut-like suit when flying. They breathe 100% oxygen and wear UCDs--urinary-collection devices--for obvious reasons...
