...Leather was once processed by soaking untanned skins in a solution of dog manure. No one enjoyed using this offensive reagent, and tanners rejoiced when its action was traced to enzymes that could be supplied from pleasanter sources.

But most industrial enzyme users shy away from living ferments, which are hard to control. The modern method is to use comparatively pure enzymes that have been separated from the living organisms that produced them. A leading practitioner...

Ewen Cameron, imaginative and resourceful head of Montreal's famed Allan Memorial Institute, was impressed by the fact that as his patients grew older, the amount of RNA in their cells decreased. Although the plausible theory that the imprint of memory is reflected in changes in RNA molecules (TIME, Feb. 10, 1961) has not yet been proved, Dr. Cameron wondered whether patients with memory defects might be helped by booster doses...
Human RNA was not available, so Dr. Cameron settled for a similar chemical: RNA extracted from a yeast. Repeated massive, intravenous doses gave the patients stomach upsets and cramps, which required additional medical treatment. But patients suffering from hardening of the brain's arteries and a group classed as presenile showed marked improvement in their memory of recent events. More advanced cases (listed as senile) got no better, Dr. Cameron told the Society of Biological Psychiatry, but he and his researchers are encouraged. They are working on ways to reduce RNA's undesirable side effects and are trying...

Some 25% of all arrests and prosecutions in South Africa are for liquor offenses; last year 312,520 liquor cases went to court, including 1,602 arrests of Africans for possessing yeast without a permit...
