Could the future covid variants cheat our immune system?

That's a good question. The fact is that new viruses are forming all the time. That means we cannot even know what kind of virus causes the next pandemic virus. The virus that causes the next international epidemics is most probably coronavirus.

The reason for that is that coronaviruses are the most common virus-type that travels through the air. The structure of that virus type makes it very resistant to chemicals that can destroy its genomes. The thing that we must realize is that the next pandemical virus might be advancing in some jungle. And there are lots of people, who cannot go to tests and who don't even care about their health.

If there is no ability to make the tests of infected people there can be many viruses in some areas. And the thing that makes the respiratory tract infections very hard to separate. The first symptoms of those virus infections are always similar. But lethal infection starts to separate from the "harmless infections" soon.

The problematic thing is there are people. Whose immune defense is passive or it cannot fight against viruses and bacteria. For those people who have AIDS or some other reason, their immune system is not working all kinds of infections are dangerous.

The thing that activates the immune system is the antigens of the virus. If the researchers can predict the form of those antigens they could make vaccines before the epidemics start. But the problem is that there are maybe thousands. Or even millions of viruses and their variants all around the Earth. And that makes the creation of the vaccines against every each of them impossible. When a virus will infect the new cell line or cell group it connects some parts of the genomes of those cells in its DNA or RNA.

And this means the transformation of the viruses is incredible. The transformation means. Sooner or later, the vaccines lose their power because the surface antigens of the virus are chanced. And that means the immune system cannot detect those new variants of the original viruses. And that means the creation of the new vaccines must begin.

What caused this pandemic? The fact is that the viruses are sometimes escaping and infect people during normal vaccine research. During the testing, there is always possible that the living viruses are slipping into the test animal or infect personnel who are working in the laboratory. The origin of the COVID-19 remains unknown.

The key question is when those animals that transmit viruses to people got the virus? Are they brought from Africa? Or if they are local what transferred those viruses to the animals that transfer them to humans?

Maybe some Chinese serviceman accidentally brought it from Africa. Or maybe somebody sold infected animals in the marketplace accidentally. I don't know what kind of inspections are made on those animals. And if somebody made a mistake in the secretive laboratory in China. That person would not confess that thing.

Maybe that virus came to China with tourists or some Africans have sold the animals that infected people from Africa outside the customs. In that case, there was no veterinarian's inspection when somebody brought those infected animals to the country or the marketplace. Nobody knows where those animals got that virus. And that information would help to find out the origin of that pandemic.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Could this be the thing, that some people don't want you to know about zombies?

Could this be the thing, that some people don't want you to know about zombies? The simplest way to control zombies, which are made by using tetrodotoxin, which is called "zombie poison" is to use the automatic dispenser, which is normally used in diabetes treatment. In this case, the dispenser would be loaded by using tetrodotoxin. If the level of this poison is right, the person would be totally under the control of other people. And if the system cannot detect this poison there is a possibility to make the laboratory experiment when the staff will follow the decrease of the tetrodotoxin, and then the system can use a simple clock, which will inject poison to the body of a victim after a certain time. This would be an effective tool in the hands of military and counter-terror operators. Those zombies can be captured enemy operators, who will send back, and then they just kill their ex-partners. By using genetically engineered bacteria could be possible to create t...

The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like.

. The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like. Above is the image of the nano-submarine. There is introduced an idea, that this kind of system would equip with living neurons, which makes it like some kind of artificial bug or mosquito. The idea is that the robot can take the nutrient by using the robot tube, which acts like a proboscis. The neurons can get nutrients and the rest of the machine can use small fuel cells or the energy to that system can deliver by using the radio waves. Futurologists are thinking about the ideas, what the hybridization of the neurons and machine would look like? Could the hyper-technical civilization look like the group of midget submarines? Those submarines might take nutrients for the neurons, what is living in them. The purpose of the midget submarines, which might be size less than a couple of millimeters would maximize the survivability of the neurons. One of the most intere...
