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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
