"Diamond Princesses" also cry: why the coronavirus infected every sixth on board a cruise ship

"Diamond Princesses" also cry: why the coronavirus infected every sixth on board a cruise ship

On board the Diamond Princess cruise ship in February 2020, there was a real rampant Covid-19 epidemic. The ship was quarantined, during which, in theory, passengers were supposed to sit out in their cabins. Despite this, one in six fell ill there. Outside of China, nowhere else is there such a number of infected people - in no other country. They began to say that this ship is the prototype of the future coronavirus epidemic around the planet. Like, since quarantine did not help here, it means that it will not contain the disease in the world

After measles and mumps, fewer heart attacks and strokes - and this is a reason to strengthen vaccinations

After measles and mumps, fewer heart attacks and strokes - and this is a reason to strengthen vaccinations

Those who have had measles and mumps in childhood are less likely to suffer from heart attacks and strokes. Based on this, anti-vaccine specialists are promoting another campaign against vaccinations against these diseases on the Internet. We figure out why childhood illness can reduce the likelihood of an adult and why, despite this, it is worth vaccinating children against measles and mumps

Coronavirus in Russia: is it true that the authorities are hiding the number of cases?

Coronavirus in Russia: is it true that the authorities are hiding the number of cases?

Since the beginning of March 2020, the same idea has been spreading across social networks: Russia is full of Covid-19 patients, the authorities simply underestimate medical statistics "by many orders of magnitude." Patients with influenza and acute respiratory viral infections, supporters of this point of view, believe, in fact, suffer from coronavirus. Deaths from him will also be "formalized" under the flu and common pneumonia. Moreover, they are trying to explain the almost complete victory over the epidemic in China by similar falsifications. The version, we agree, is colorful, excites the whole

Nuclear shirt: getting closer to the body

Nuclear shirt: getting closer to the body

The incidence of cancer is increasing, and a number of scientific papers indicate that a similar situation will continue in the future. Humanity needs to find a way to reduce the number of victims of this disease. One such method is nuclear medicine. If earlier, within its framework, the necessary parts of the body were irradiated from the outside, now more and more often, pointwise radioactive substances are used from the inside. There are similar advances in the field of diagnostics. How much will this help and does "atomic" medicine have any other important occupations?

Two-faced virus: how in China the pluses of the epidemic outweighed the minuses

Two-faced virus: how in China the pluses of the epidemic outweighed the minuses

The beginning of the introduction of quarantines in the West led to a sharp drop in stock indices and fears of a complete economic collapse. Many expect mortality to rise sharply following the economic downturn. However, historical experience shows: in fact, mortality during depressions and recessions decreases markedly. And it's not just about history. The latest data show that in China, the Covid-19 epidemic has saved dozens of times more people than it killed. In theory, the rest of the world can achieve the same cut

New Pfizer Vaccine Publications Show High Efficacy And Potential Unusual Undesirable Effects

New Pfizer Vaccine Publications Show High Efficacy And Potential Unusual Undesirable Effects

The developers of the American-German vaccine published the results of its clinical trials in a scientific journal - and they showed good efficacy. At the same time, the American Food and Drug Administration (FDA) published a document: according to it, part of those vaccinated with this vaccine received temporary paralysis of part of the face (Bell's palsy), which, however, quickly passed

Debriefing: how Naked Science and Novaya Gazeta counted mortality from coronavirus in Moscow

Debriefing: how Naked Science and Novaya Gazeta counted mortality from coronavirus in Moscow

He who does not try is not mistaken. In the situation with April 2020, we trusted the official figures and tried to explain the excess mortality by other factors that are consistently taken into account in the scientific community. But on June 10, data on excess mortality in Moscow for May 2020 were published, showing that our hypothesis was largely wrong. However, not only her: the forecasts of our opponents also turned out to be inaccurate. We have made an analysis of the errors. We hope other publications will follow this example

Scientists from Wuhan did create an "artificial" coronavirus - but not the one

Scientists from Wuhan did create an "artificial" coronavirus - but not the one

Another wave of conspiracy theories about the man-made Covid-19 pandemic blame the Wuhan virology laboratory for everything, the researchers from which actually constructed a virus close to the current one in 2015. And yet he was very different - this is not SARS-CoV-2. According to the new work, their genes do not coincide by tens of percent, the gap is much larger than in humans and chimpanzees. There are other factors that practically exclude the possibility of artificial origin of any virus, similar to that

Does alcohol reduce mortality or does it increase? Why scientists argue and who is right

Does alcohol reduce mortality or does it increase? Why scientists argue and who is right

For a dozen years now, some studies have been saying that alcohol is an absolute evil. Others find it reduces mortality from mass disease. The authors of those and other works use similar scientific methods, but come to opposite conclusions. Let's try to figure out which of this is true

Argentina questioned the need for a second dose of Sputnik for those who had recovered

Argentina questioned the need for a second dose of Sputnik for those who had recovered

Argentine researchers studied the reaction of the body of those who had had Covid-19 to the first and second doses of Sputnik and discovered an unexpected fact: for some reason, after the second dose, the level of antibodies in those who had recovered did not increase and even dropped slightly. For this reason, they propose to vaccinate coronavirus survivors only with the first dose of the Russian vaccine. This will also make it possible to quickly vaccinate the local population: the demand for Sputnik in Argentina is extremely high, and supplies from Russia are still limited. Work can have

Russia has emerged as the leader in mask-neglect and distancing. Apparently, this is the main factor in the record mortality of its citizens from the coronavirus

Russia has emerged as the leader in mask-neglect and distancing. Apparently, this is the main factor in the record mortality of its citizens from the coronavirus

German scientists analyzed the tendency of the inhabitants of eight countries to wear masks and observe antiquarian measures. The most "unwilling" were the citizens of the USA, Sweden, Poland and Russia, and the most inclined were the Germans, British, French and Spaniards. The researchers concluded that the lower the propensity, the higher the mortality rate. In our country, the real death rate from Covid-19 is several times higher than the official death rate from the headquarters, that is, in fact, the effect of neglecting masks and distance is probably more significant. R

Russian vaccine against coronavirus: dangerous to administer or another anti-vaccination hysteria?

Russian vaccine against coronavirus: dangerous to administer or another anti-vaccination hysteria?

In Russia, for the first time in the world, a vaccine against coronavirus has been registered, but it seems that no one is happy about this. Many people write that it is impossible to release medical products so quickly, because they will not have time to pass all the checks. Others describe it as a "massive human experiment." It is alleged that even before the third phase of clinical trials, "Sputnik-V" will be administered to millions of Russian citizens - in the next month. It is reported that the new vaccine has many adverse reactions, but it allegedly provides few protective antibodies. It seems

Hydroxychloroquine and Azithromycin: New Efficacy Data Against COVID-19

Hydroxychloroquine and Azithromycin: New Efficacy Data Against COVID-19

At the end of March, Donald Trump urged on his Twitter to use a combination of the antimalarial drug hydroxychloroquine and the antibiotic azithromycin to combat the COVID-19 epidemic, noting that this is "one of the most important and turning points in the history of medicine." But the authoritative scientific journal Science called his initiative "sheer madness." Who is right and is there any new evidence of the effectiveness of these drugs against coronavirus?

A shot of truth: Naked Science reporting against vaccination myths

A shot of truth: Naked Science reporting against vaccination myths

We sent a person to the third phase of clinical trials of "Sputnik-V" to see on the spot how things are with vaccination, and to better understand how the general population will be vaccinated ("civil vaccination"). Are the doses of the drug being secured by the police like in the UK? Is it true that the elderly are not vaccinated, and 42 days after vaccination they should not drink? Do doctors really don't want to inject themselves with the vaccine? What is their opinion on its effectiveness? What are these "unwanted effects"? And finally, why
