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.

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.

Aphrodisiacs: deception or panacea?

Despite the lack of scientific evidence that any of the aphrodisiacs sold can be used to increase libido, as well as information that some aphrodisiacs are not only ineffective, but sometimes dangerous, people continue to look for a magic drug that will make them sexually irresistible.

Genetic aspects of skin diseases

Hereditary skin diseases have evolved in recent years from a secondary topic to an important focus of basic and clinical research. There is no doubt that genetics has an important role in solving the pathogenesis of many common skin diseases with a family predisposition, as well as in the development of new ways to treat these diseases.

Since the beginning of the mass use of such creams, the incidence of skin cancer in the United States has increased by 90%!

Menopause: another possible reason

One of the most unpleasant and incomprehensible events in a woman's life — menopause — has received a new explanation. Scientists blame the stopping of the "birthing mechanism" of daughters-in-law who fought for power in a primitive family.

The weight of innovation: "competent" numbers versus common sense

Is it possible to successfully and in a short time to transfer the Russian economy to the "innovative rails" without clearly defining the key benchmarks? In a conversation between Konstantin Kiselev, Executive Director of the Open Economy Foundation, and Gennady Shepelev, Head of the Department of Programs and Projects of Rosnauki, some likely arrows of the main movement "towards innovation" are outlined.

The fantastic experience of Japanese scientists opens the way to recognition in the human brain and those images that he has never seen in reality – dreams or imaginary worlds. Just imagine the work of an artist or designer who just sits in an armchair and, closing his eyes, comes up with images that immediately appear on the computer screen.
