The Origins of Life on Earth A Retrospective on Ideas
Recent ideas about the origins of life are becoming less parochial. It is no longer taken for granted that the original forms were caricatures of the simpler existing organisms and that the problem, in essence, is to devise means by which proteins, and small molecules of the types which dominate contemporary biochemistry, could have appeared. Possible roles for mineral crystals, tars and gums, either primordial or made by the action of ultraviole…

International conference report, leaf protein research gains status
Leaf Protein: Production and Use
Protein extracted from leafy crops is potentially the most abundant protein concentrate. It is an acceptable complement to green vegetables cooked in the normal manner, and it replaces oil-seed products and fishmeal in animal feeds. It is so easy to make, and its value as a source of protein and vitamin A is so obvious in human feeding trials, that it is surprising that it seems not to have become part of the culinary tradition anywhere. It is no…
Optimal exploitation of leaf carotene
Leaves are an important source of β carotene (provitamin A) and their more extensive use, as vegetables cooked in the conventional manner, would do much to diminish the still widespread occurrence of vitamin A deficiency. When leaves are used on the domestic scale, their value could be enhanced by avoiding collection in the middle of the day, when they contain least carotene, and by collecting them from those parts of a plant where they contain m…
Fluctuating Food Fashions
Food fashions have swung back and forth dictated by chance, by religious taboos, by custom and by law. Examples here considered cover the eating of horse meat, of offal and of blood human milk, dark green vegetables and sugar. Overeating, human diets, protein requirements, child nutrition and the prevention of scurvy are also discussed. But who makes food policy is difficult to answer, a new crops and technical developments will continue to influ…
Commentary: The comprehensibility of our food requirements
Although different species use many different substances to solve what seem to be essentially the same physical problems, the basic metabolism of all organisms depends on the same small group of essential nutrients. Preference for the more abundant elements is understandable. Nevertheless, all organisms need traces of some rare elements; only relatively rare species can make extensive use of them. The small use of abundant elements such as alumin…
Report: Worldwide interest in leaf protein
Possible consequences of very large-scale use of unconventional energy sources
Would food and health services benefit from a more intimate union
Infection From Worms to Nucleotides
Grant-giving bodies often use the word timely, sometimes coupled with the word promise, to describe the principles used in allocating money. Research cannot be undertaken certain theme until technical restraint have been removed, namely until it become possible to attain certain levels of old, heat, magnification or pressure. Even a superficial survey of some aspects of the history of biology suggests that, apart from such physical constraints, t…

The world food supply
Focal Points. A Global Food Strategy
The direction of beneficial nutritional change
In response to changes in agricultural technique, conditions of employment, example and advertising, the food habits of many communities are changing. This demolishes the idea that food habits are immutable. Many changes are probably for the worse, but a few are beneficial and some of these were deliberately planned by organisations concerned with human welfare. The sources from which increased supplies of food (especially protein‐rich food) coul…
The Social Impact of Modern Biology
Increasing the usefulness of internationally controlled research
In places such as the wet tropics where nutritional deficiencies are obvious, there is reason to believe that nutrition surveys are often undertaken so as to postpone the time when something practical is done. Farming methods developed in drier and cooler regions may not be applicable. The research on agronomy and food science that is needed is not likely to be undertaken by industry except under contract from a government or International Agency…

The Biosphere
The Scientific Basis of Contraception
For centuries the scientific basis of contraceptive methods has consisted almost entirely in the recognition that the male ejaculate contained a factor essential for fertilization. Methods were therefore evolved for preventing the entrance of semen into the higher levels of the female reproductive tract, principally barriers and spermicides of various kinds. The scientific basis for more effective contraceptive techniques broadened only in the tw…
