...trouble traces to the same rise in beef prices that brought prosperity to the feed lots in previous years. During 1973, budget-conscious housewives switched to more economical sources of protein, such as chicken, beans and cottage cheese. Per capita beef consumption dropped for the first time since the mid-1960s, from 85 lbs. in 1972 to only 80 lbs. last year. The slackening demand led retailers to lower prices about 7% from last September's highs, and also to cut back orders from meat-packing houses.

...good times, feed-lot operators buy 500-lb. to 700-lb. calves from ranchers, gorge them on a special, high-protein diet until the cattle reach the optimum slaughter weight of 1,100 lbs., then resell them to packers for about the same price per pound that they paid. They corral a profit if the expense of putting the added weight on the animals is less than the price that the added poundage brings...
...device to break down and emulsify heavy liquids. His process is still widely used to prepare Worcestershire sauce, ketchup, cosmetics and paint. Five years ago he set out to design a more advanced machine, which would have enough force to rip apart single-cell organisms, releasing their protein to provide a cheap and plentiful food supplement. He built the Cottell Ultrasonic Reactor, which is hardly larger than a long loaf of bread and resembles an electric drill. The reactor is a mechanical torture chamber in which liquids and semiliquids are broken down under pressures of 1 million...
...polarization optics to explore the inner workings of cells, and studied molecular biology before the term was invented. Head of the team that was first in the U.S. to use an electron microscope for studying biological tissues, he is also well known for his work on collagen, the clear protein material that fills the spaces between cells...
...American inflation has been fanned in recent years by such disparate events as the Arab-Israeli war, a low Soviet grain harvest, copper-industry strikes in Africa and even a change in the ocean currents off Peru (which temporarily wiped out the catch of anchovies, a key source of protein in animal feeds, causing panicky foreign buyers to bid up the price of U.S. soybeans...
