Interstellar Exploration Alliance Pacific Base, Institute of Biochemistry. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

In a laboratory with a mysterious atmosphere, the strong, lingering smell of chemicals permeates the air.

It's a laboratory, but it's actually more like a hospital morgue.

That's right, this is the laboratory of Dr. Minch, a well-known life scientist in the Interstellar Exploration Alliance.

Many people have heard that there are a lot of frozen corpses of the world's richest people in Dr. Minchi's lab, and Dr. Minchi is working on how to bring these goddamn big guys back to hell......

Of course, the actual situation should not be as terrifying as the rumors, but frozen human corpses do exist, but not necessarily all of them are the corpses of the broadmen, most of whom are scientific volunteers who donate their bodies.

Of course, they must also hope to return to the human world one day.

The laboratory is quite quiet, and the dim light accentuates the creepy atmosphere.

Suddenly, the sound of fragmented footsteps came from the depths of the laboratory.

A deep voice rang out.

"You have a lot of guts, and people from other research institutes generally don't come to my lab."

"It's nothing about corpses, but why don't you make the lab brighter, look at the ...... of the black light?"

The two people who came out of the depths of the laboratory were none other than Dr. Mingqi and Yuan Haochen.

"There's a reason for that, and the best storage conditions are in a low temperature and dim environment." Dr. Minki's voice still exuded an eerie aura.

"I see!" Although Yuan Haochen was in harmony, he couldn't help but complain in his heart, "You are deliberately scary!" Sure enough, it's a perverted place, but fortunately, I'm used to seeing corpses and blood during the Eastern Han Dynasty! ”

"Go to the office and sit down, I have some information for you!" Dr. Minchi said with a mysterious smile again.

"Okay."

With that, the two of them left the gloomy lab and headed for Mingqi's office.

Yuan Haochen came to visit Dr. Mingqi today, definitely not to visit the frozen corpse, his purpose is to learn about the hibernation technology of interstellar travel.

Space travel is a very long and boring process, and in order to ensure the normal survival of astronauts, it is necessary to prepare enough food, water and oxygen.

With the extension of time, the waste excreted by it will gradually increase, and the carrying capacity of the spacecraft is limited, and it is necessary to ensure that there is enough power and enough necessities, which greatly limits the process of human exploration of outer space.

If the spacecraft enters a designated orbit, the astronaut goes into hibernation. In hibernation, their heartbeat, pulse, and metabolism are all reduced to a minimum. During this time, they require very little food and oxygen, and produce very little waste, which will greatly extend the time that astronauts can travel in space.

In addition, astronauts are asleep and do not have to look at the boring scenery of outer space all day, for them, this kind of long trip will be much better.

All mammals may have the potential to "hibernate", and even humans have this ability.

And all scientists have to do is flip this potential switch.

If astronauts are allowed to "hibernate" during a long space voyage, then a manned spacecraft will be able to land on distant planets.

"Hibernation techniques go in two directions."

Dr. Mingqi sat in a chair, his eyes shining, and his hands were gesturing in front of Yuan, who extremely suspected that this was a problem that Dr. Mingqi had developed from dissecting corpses for a long time.

"First, the rapid freezing of human beings, although it should work in principle, and we have had limited success in animals, but there are still technical difficulties. The difficulty is mainly in the destruction of cells, tissues and organs during the freezing and thawing process. ”

"Like the frozen broadmen we just saw?" Yuan Haochen's pupils shrank and asked in a low voice.

"Yes, but we're only responsible for freezing right now, and we can't provide defrosting services for the time being." Dr. Minchi continued with a wicked grin.

"Second, traditional hibernation, similar to bear-like hibernation, keeps the body temperature at about 10 degrees Celsius, and the body's metabolism slows down. This technology is relatively feasible. However, traditional hibernation still has a high metabolism compared to freezing, and it cannot meet the needs of ultra-long-distance interstellar navigation. ”

"How long does a traditional hibernation last?" Yuan Haochen asked curiously.

"If you follow my technique, up to one year, that's the current limit. If you continue to hibernate for too long, you will fall into a coma, which is dangerous. It was as if Mingqi was saying something terrible.

"I've heard of someone in the medical profession who has been in a coma for 37 years!" Yuan Haochen thought of this and casually mentioned it.

"Yes, he'll continue to break the human record for coma, because he'll probably never wake up. Hohoho~"

The smile on Dr. Minch's face grew even more eerie.

"I'll go~" Yuan Haochen was very annoyed by this laughter.

"But hibernation and coma are two different things. There are two types of human sleep: rapid eye movement sleep (REM) when we dream, and non-rapid eye movement sleep (non-REM). The latter is very important, for example, when you stay up late watching movies and go to bed, what you want is actually non-REM sleep. Non-REM sleep refuels our body. We cannot afford to lack this type of sleep for a long time, and the same goes for most animals. ”

"Oh."

"Let's take a look at these two research materials first!" Dr. Mingqi suddenly became serious and handed the information to Yuan Haochen.

Yuan Haochen took the information, and his eyes quickly flickered.

[Fact 1: Researchers at the Polar Research Institute have successfully revived tardigrades that have been frozen for more than 50 years for the first time, which will improve the understanding of the mechanisms and conditions for the long-term survival of cryptozoans.]

Water bears, also known as tardigrades, are commonly known as tardigrades, and there are more than 900 species recorded, most of which are distributed worldwide. They are extremely small, with the smallest measuring only 50 microns and the largest measuring 1.4 millimeters, which must be seen with a microscope. It is the most vital creature known on Earth, surviving in a frozen, boiled, air-dried state, and even in a vacuum or under radioactive rays. Once it is put back in its normal environment, it can still return to its normal state.

According to the Physicists Organization Network, these tardigrades were discovered by science 50 years ago in bryophytes at Showa Station in Antarctica, and were kept in a refrigerator at about minus 20 degrees Celsius. After 50 years, scientists are determined to thaw it to learn more about its performance.

The research team placed these tardigrades (divided into SB-1 and SB-2) in a warm environment, and on the first day of thawing, they all showed signs of vital activity, but SB-2 did not eventually survive, and SB-1 began to move and feed after a week, recovered after two weeks, and laid 19 eggs, 14 of which hatched successfully. These hatched newborn pups are normal, free of defects and abnormalities.

The study found that these tardigrades were apparently able to withstand the extreme conditions of being completely frozen for decades, and that they could put themselves in a "cryptophytic state", in which they slowed or stopped their metabolic activity for long periods of time. 】

[Fact 2: A Norwegian skier who fell into icy water, after being rescued, was able to wake up from a state where he had no heartbeat, no breathing, and a body temperature of only 13.8C.]

A man who had been trapped in a snow-covered car for more than two months was found in Sweden, and doctors examined him and found that he survived because his core body temperature had dropped to about 31C and remained stable, which was like hibernation.

A terminally ill patient dies without an organ transplant, and every breath and heartbeat of his heart brings death closer. In hibernation, lemurs' breathing rate can drop to once every 20 minutes, and their heart rate can drop from 200 to 4 breaths per minute in the normal state. If this patient can go into such a state of hibernation, there will be more time to wait for an organ transplant. Medical treatment is also trying to hibernate some patients with incurable diseases, and then resuscitate them when medicine can solve the problem in the future.

Scientists are experimenting, reducing human body temperature is the most critical part, the research team of Pittsburgh Hospital in the United States will be low-temperature normal saline implanted into 10 critically ill patient volunteers, so that the body's metabolism slows down, physiological function is weakened, so that its body temperature drops to 10C, reduce human body function to a state close to death, after a period of time, re-inject blood into the volunteer's body, carry out "warming resurrection", the whole process is close to the hibernation of ectothermic animals. This technology can buy more time for critically ill patients. 】
