Chapter 875

On weekdays, what kinds of conventional ultraviolet disinfection, ozone disinfection and so on will not be said, the virus control system in the laboratory still has a variety of drug killing programs.

One of the most extreme measures is to directly start the laboratory self destruction program. If this program is triggered, the whole laboratory internal self destruction system will directly use the high temperature of more than 1500 ℃ for 10 minutes after all researchers evacuate!

No virus or microorganism can endure such a long time of burning under such high temperature. At present, human beings have the highest record of high temperature resistant bacteria, that is, 200 ℃. Even the most powerful water bear can only survive for 2 minutes at 151 ℃!

As for why origini didn't start such a program when the researchers were still there, just like the red queen in "biochemical crisis", in order to ensure that the virus did not leak to the outside world, the whole laboratory was directly sealed, and even the researchers were killed together. The main reason is that such a situation was avoided in design.

Because the bsl-5 laboratory designed by the company is more advanced and safer than BSL-4 laboratory, its core is different. The whole laboratory is divided into two independent areas: high-risk area and low-risk area.

All the work in high-risk areas are the second-generation intelligent robots specially customized by the robot laboratory. Researchers carry out those high-risk experiments by operating these robots. Of course, the risk of such experiments is reduced to the lowest.

So even in the case of mutated virus and mutated microorganism leakage, researchers in low-risk areas have enough time to evacuate after strict killing procedures.

After they leave, the original will completely close the whole laboratory, start the self destruction system, and ensure that no virus will leak out, because the whole bsl-5 laboratory, like the biosphere laboratory submitted by Liu Helong, adopts a double-layer fully enclosed design.

Even if the initial detection of virus leakage, in a certain period of time, they are absolutely unable to break through such a layer of defense.

The reason why we know the danger of these studies is to carry out research for the future of mankind. If we want to enter the era of interstellar migration, these studies must be done!

Because human life is so fragile, even Lei Tiantang's physical fitness research is 10 times stronger than that of ordinary people. In Kuafu's simulation calculation, there are many kinds of viruses and microorganisms that have mutated in the laboratory. His physical fitness can not resist, let alone ordinary people.

In the company's future space program, short-term missions include landing on the moon, Mars and asteroids. In these missions, astronauts are required to fly in space for a long time in space.

In order to make these huge space projects safe, the company's scientists began to think in the micro direction, targeting small bacteria and micro-organisms.

Because according to their previous experiments in the laboratory and the relevant experimental research carried out in the space station laboratory, it shows that various strong radiation effects in the universe are enough to make some bacteria and microbial genes mutate abnormally and express stronger toxicity!

And these mutated bacteria and microbes will be very lethal to astronauts who will fly for a long time in the future. So far, even many viruses and microorganisms without mutation can not be treated and protected, let alone these more lethal ones!

A long-term flight in space requires not only a series of life support equipment, but also physical health. For example, if we fly to Mars according to the previous spaceship technology, the one-year Mars flight is a huge challenge, and all kinds of unknown situations may occur.

If astronauts get sick in space, what should we do? For example, microorganisms like Salmonella may become more lethal in microgravity environment, and microgravity environment can change the activity habits of microorganisms, which may make the treatment methods on earth effective. Therefore, these are the major unknown factors facing human space flight in the future.

And in the long space flight, if there is the problem of mutated infectious diseases, it is a very terrible thing for the astronauts in the whole spacecraft!

There is also the impact of microorganisms on space activities. When spaceships fly in space and in future colonial advance bases, we are like a sealed can, a completely closed system.

In such an environment, we must have a very detailed understanding of these bacterial communities that may have an impact on our human survival, and conduct a comprehensive spatial study. It is very important for us to conduct a comprehensive spatial study, whether it is beneficial or harmful to the human body.

In the past ten years, the research on microorganisms in space has shown that: microorganisms often exhibit strange behaviors in space, some microbial communities can become very large, some microbial communities grow slowly, some microbial shapes change, or they have strong resistance to antibiotics, making antibiotics ineffective.

But researchers are not sure which bacteria will develop a strong pathogenicity in microgravity, but the possibility of such a mutation has been discovered, and this is what the researchers are worried about.Let's take the case that Salmonella was sent to the South Tianmen space station in the laboratory for testing. According to the experimental observation, the infection ability of Salmonella cultured in space to mice is three times higher than that in the laboratory on the ground.

This is because space radiation or space environment changes the Salmonella gene, and the mutated gene is more toxic. However, astronauts are not very resistant to microgravity, which increases the toxicity.

There is also a published study by a research group, which shows that there is interaction between different pathogens in the space environment, which can also become more lethal.

For example, a recent study by them found that the effect of space environment on another bacterium (Pseudomonas aeruginosa) has genetic characteristics. This phenomenon is also found in some Salmonella bacteria. The mutated gene can continue to express after reproduction, but the researchers have not confirmed that the space environment of Pseudomonas aeruginosa can become lethal.

Of course, researchers have also found that microbes in space can help human development. On the one hand, they can help develop better vaccines. Experts in the laboratory cultivate microbes brought back from space in the laboratory, develop a new vaccine, and improve the role of the vaccine.
