Human beings are genetically adapted to conditions of scanty and irregular nutrition. In case of food abundance this advantage turned into a significant part of population’s predisposition to “diseases of civilization”. This conclusion has been made by I.S. Liberman, Doctor of Sciences, based on his own data and findings of other investigators.
Atherosclerosis, type II (insulin-independent) diabetes, primary hypertension, and obesity often accompanying them are called diseases of civilization. Within the last decades, these diseases are found with younger people and are often found with patients at the age over 30. According to some researchers, practically everybody has atherosclerosis of aorta and coronary arteries, their manifestation intensifying with years. Such mass distribution, in fact, pandemic of vascular pathology allows to assume that mankind is predisposed to this pathology in the conditions of civilization. Naturally, the degree of such predisposition varies with different people.
The genotype, which determines disposition to diseases of civilization, was formed at the early stages of the mankind development. Its nutrition was then scanty and irregular, and in these conditions the possibility to eat one’s fill for future use was very important. Excessive fat and carbohydrates were laid in the adipose tissue, and mature adipose tissue was a big advantage, particularly with women, who had to give birth and to nurse children. Men spent a lot of energy on hunting, cattle-raising and farming, therefore, their muscles were better developed. The majority of people did not enjoy abundance of food, and there was certain balance between caloric content of food and energy consumption.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
