Phantoms of the wave genome

The bulletin "In Defense of Science" No. 4 again exposes the pseudo- and anti-scientific activities of a number of "scientists" that harm the development of science, the health of the population, weaning people from critical thinking and contributing to the spread of obscurantism. Two articles are devoted to the theory of the "wave genome".

Stem cells: the present and the near future

Most likely, the breakthrough in advanced medicine associated with stem cells predicted in the next decade will be based not on embryonic, but on the so–called induced pluripotent stem cells (iPSCs, from Induced Pluripotent Stem Cell) - ordinary differentiated mature cells reprogrammed into a state of pluripotence.

A small mutation of one gene has huge consequences for the whole person

The replacement of just one nucleotide base in the regulatory part of the gene encoding the muscarinic receptor M2, sensitive to the mediator of the nervous system acetylcholine, affects the number of such receptors and, by changing the tone of the parasympathetic nervous system, affects intelligence, social status, health and life expectancy.

The place of biology in the hierarchy of sciences

Biology – the science of life and living objects – traditionally belongs to the complex of natural sciences and is usually considered along with the main ones – physics and chemistry. But even with the most superficial comparison, some features of biology attract attention, distinguishing it from a number of natural science disciplines.

Cancel aging: how and why

Aubrey De Grey: from what we know about aging today, we can identify seven key points and try to influence these "weak links". This is my "Strategy for Achieving Negligible Aging by Engineering Methods" (SENS). The goal is to create a technology accessible to every person, with the help of which it is possible to restore the body to any degree of rejuvenation and maintain it in this state for any time.

Free radical theory of aging: new data against

Over the past forty years, the free radical theory of aging has dominated official science, explaining age-related changes by the action of reactive oxygen species on cellular structures. However, experimental data are gradually beginning to appear, proving the absence of a link between oxidative stress and aging.
