...used to get an estimated 30% of their daily calories in fats now get 40% or more in that form; Keys recommends a cutback to between 25% and 30%. More important, only about half of this fat should be saturated (the chemists' way of saying that the available carbon atoms in the molecule all have hydrogen atoms attached), and the rest unsaturated...
...filtering the body's waste products from the blood so that they can be voided in the urine. A variety of things can cause an abrupt kidney shutdown: shock with heavy blood loss (after surgery or an accident), some severe infections, mismatched transfusions, and many poisons. Of these, carbon tetrachloride attacks the kidneys directly; most are general poisons (often, overdoses of common drugs such as barbiturates and even aspirin) which the overloaded natural kidneys cannot void fast enough...
...stream of gas followed the ash and spread into the vacuum above the moon's surface. The gas contained carbon molecules of various sorts, and ultraviolet light from the sun made them glow brilliantly, accounting for the bright streak on the spectrogram...
...Venusian atmosphere contains carbon dioxide. This information does not mean (as many science-fiction writers seem to think) that Venus under its clouds is covered with lush jungles. Earthside plants need carbon dioxide, but their flourishing presence on earth is the reason why the earth's modern atmosphere contains only a trace of CO2. This abundance of carbon dioxide in the Venusian atmosphere is excellent proof that the planet has no earthlike plants...
...Urey still thinks that the clouds in the Venusian atmosphere may be made of water droplets like clouds on earth, but few astronomers agree with him. Dr. Kuiper thinks they are made of fine dust particles of carbon suboxide (0302). In an attempt to prove this theory, he made a mixture of carbon dioxide and carbon monoxide and exposed it to assorted radiation at the Argonne National Laboratory. Sure enough, carbon suboxide formed, and its molecules stuck together to make particles of yellowish polymer...
