At the beginning of the year 2022, three astrobiologists ran a fascinating thought experiment: they claimed that the entire Earth was about to become an intelligent organism. The meaning, as you can understand, is not that there is a mind at the core of the planet that makes decisions for the creatures living on it. Exactly the opposite: in the future they describe, all living beings on earth will participate together in a process that amounts to the creation of one collective intelligence

Deepfaked movies can cause harm to real people who appear in them and even cause wars between countries. No wonder the US and the EU recognized Deep Fake as an immediate threat to democracy

Let's start with reassurance: the Omicron *doesn't* cause multiple sclerosis. But a new and comprehensive study reveals that another virus does. And this also has consequences for dealing with the corona virus. And no, it's not clickbait (although it's really successful).

In 1991, cosmonaut Sergey Krikalev made one of the most difficult decisions of his life: to stay on the Soviet space station indefinitely. He did this even though he knew that the country that sent him into space had disintegrated, and there was no one to replace him

Researchers from the University of Vermont succeeded in creating new life forms with the help of artificial intelligence when frog embryos were used as the raw material. A first step in the field of synthetic biology. The researchers call the new creatures "xenobots", meaning extraterrestrial life

In recent days, the World Health Organization has given a unique name to the strain of the corona virus, which has undergone many mutations and may bypass some of the defenses * Dr.Roey Tsezana explains the reason for the concern

So who is right? Those who intentionally infect or fear infection in schools? What are the effects of the virus on children? What do we know after a year and a half of illness, and a few more months of infection with the delta strain? What can we expect with back to school at best, or partying at worst?

Patients with the delta strain produce a thousand times more viruses than patients with previous strains of the corona, this is one of the most contagious viruses. There are many open questions about it, including what is the mortality rate from it, and what is the strategy required to defeat it

A survey distributed in eight European countries in 2019. According to the survey results, about a quarter of all Europeans would like artificial intelligence to replace the politicians they currently suffer from * 91 million Europeans support artificial intelligence instead of politicians

The new claim that has recently been circulating on social media is that among the vaccinated, the level of antibodies in the blood drops in a short time - and thus people find themselves exposed to the virus a second time. We checked whether this is true (in ten percent of cases) and whether it means that the person is no longer vaccinated (no)

13 years ago, Mike Winkleman created a computer illustration of one of his relatives and published it on the Internet. The next day, he uploaded another illustration. The next day - another one. And so on and so forth, until last month he received 69 million dollars for all the paintings. He thereby created a new currency - NFT

When the next dangerous virus is released into the world's air, it will find a deep moat courtesy of science that will make it possible to understand its operation, and a wall in the form of technology that will stop it. The way the virus works will be deciphered within a day. The drugs and vaccines will be developed within a week, with minimal clinical trials thanks to the precision of the cell and body simulations.

In the current article, I want to go over the way in which the Pfizer and Moderna vaccines were developed, how they received emergency approval, and what this means in the end for their level of safety and effectiveness. To do this, we will go through each step in a typical vaccine development and approval process, and see how it went over the past year

Contrary to the popular opinion of some of the commenters here, I'm not just trying to scaremonger about the virus. Therefore, today I want to cover the most surprising trend in the last five weeks: the incidence of corona is decreasing in large parts of the world. Is this a seasonal phenomenon? Do the vaccines work? Dr.Roey Tsezana reviews all the alternatives

A week ago a study was published in Nature in which the researchers described how they closely followed the evolution of the virus in the body of a cancer patient whose immune system was destroyed and discovered mutations that are also able to deal with a large number of antibodies produced against the virus

The discussion, in my opinion, is puzzling. Isn't it enough that the vaccine prevents the vast majority of those who receive it from getting a serious illness? But since the question comes up so often, it's worth addressing

As a result of the restrictions such as social distancing, not only the spread of the corona but also that of the flu was limited. Will the absence of a flu epidemic in both hemispheres mean that we will not know which strain to prepare for next winter?

We must start thinking far ahead - on the order of at least a year - to prevent the fourth, fifth and sixth closures. Or, if these are the obligations of reality, then at least we will enter them prepared.

The question that repeats many times comes from pregnant women who want to know if they should take the covid-19 vaccine. I do not intend to provide recommendations in this record, among other things because every pregnant woman is a special case in herself. I will try to provide all the scientific knowledge we have today, in the hope that it will help women make a more informed decision

In recent days there has been a big uproar regarding the Helsinki Committee, what it determined or did not determine, and what it means for the vaccine. So let's break down the issue, to understand what the Ministry of Health really did wrong, and what this means for Pfizer, the vaccine and the Helsinki Committee. Dr.Roey Tsezana makes order

Recent studies in Nature and Science have tried to examine the issue, but many forget that closure is only a last resort, therefore treating it as a separate solution misleads decision makers and serves the supporters of conspiracy theories
