Genome: The Autobiography of a Species in 23 chapters

The 23 chapters of the book are 23 human chromosomes. On each one, the author finds some particularly remarkable gene and, starting from it, tells about the origin of life on Earth, about where the soul "hides", about how heredity affects a person's character and abilities, about who is to blame for the fact that a person loses immunity from stress, about where do hereditary diseases and cancer come from…

Fasting does not prolong life

One of the mechanisms of prolonging life with calorie restriction, found in experiments on rodents, is a decrease in the synthesis of insulin–like growth factor-1 (IGF-1). However, as Luigi Fontana and his colleagues have shown, a low-calorie diet does not have such an effect on people.

Crisis: the worst is ahead

The financial crisis seems to have passed, says Anatoly Chubais, the banking system has resisted. The economic crisis is unfolding. Economic will turn into social exactly in the spring. Whether the social will turn into a political one is already a question of the strength of the system that has been built over the past 8 years.

Artificial bone marrow

For the first time in the world, a working model of human red bone marrow has been manufactured at the University of Michigan. Artificial bone marrow is capable of producing both various types of white blood cells and new hematopoietic cells. Perhaps red blood cells and red blood cells appear there.

No "genetically modified" girls!

The girl, who will be born any day in the clinic of the University of London, has not been genetically modeled, not to mention the creation of an "artificial gene system" unknown to science. And no one has withdrawn the gene from her, especially since simply "removing the cancer gene" would probably be even worse.

Stem selection

Having "reprogrammed" a skin cell into a stem cell, scientists insisted that medicines for all diseases would be selected individually. Expectations were met: from the skin of a baby suffering from a rare fatal disease, it was possible to create a cell line that allowed us to find the right drugs. However, the doctors did not have time to help the child.

Nanoparticles for medicine

Attaching magnetic nanoparticles to antibodies instead of fluorescent dye molecules increases the sensitivity of detecting marker proteins by about a hundred times. And ultra-fine polishing with the help of liquid suspensions of quartz nanoparticles, which are used for the same purposes in the semiconductor industry, makes the enamel so "slippery" that bacteria cease to stay on it.

How a blood clot grows

Russian scientists from the Hematology Research Center of the Russian Academy of Medical Sciences have learned to measure the growth rate of a blood clot, and now anyone can calculate the risk of their own heart attack.

Telematics

There are no words, only interjections: all this is not even the Middle Ages, but the times of primitive tribes. For professional scientists, showing the film "Water" or broadcasting a dispute with the "resurrectionist" of the dead Grabovoi is the same as hearing swearing from the screen. Who plans such "educational" programs on television? Who is responsible for their content?

Cholesterol, statins and (inflated?) sensationalism

The authors of another study on the benefits of statins propose to reduce the recommended cholesterol level several times more, and to save the population from vascular diseases, everyone should take statins for life (for only 2000 rubles a month), or even better ... add them to tap water.

Discoveries of the Year: from stem cells to genome decoding

The top ten scientific breakthroughs of the year according to the journal Science were led by the method of creating artificially induced pluripotent stem cells. Completing the list is the acceleration and cheapening of the gene sequencing process, thanks to which, in particular, 80% of the mammoth gene was deciphered in the outgoing year and preliminary results of decoding the Neanderthal genome were obtained.

About flu vaccination

There is no doubt that annual vaccination against influenza is the only real measure to prevent this infection. Without vaccination, it is impossible to prevent an epidemic of influenza and reduce the number of severe complications, as the World Health Organization wants. Moreover, influenza vaccines are the safest and most effective among other vaccines on the modern market.
