Chapter 381 A paper that will definitely change history
Chen Xiao spent a lot of time in Yanjing. When he was at the Xiaguo Academy of Sciences, he had been discussing some methods and content of gene sequencing with Wu Wei's team in the genetic laboratory.
After getting the sequencing results, he hurriedly returned to Jiangzhou.
Before leaving Jiangzhou, Chen Xiao called Shen Wei and informed her of her itinerary.
Shen Wei was overjoyed when she learned that Chen Xiao was actually in Yanjing. When she heard that he was already at the airport and was about to go back, she felt as if she had fallen from heaven to hell.
Chen Xiao could only say very apologetically: "This time I am going to the Xiaguo Academy of Sciences to do some personal things. Next time I go to Yanjing, I will definitely go to climb the Great Wall with you and see the Forbidden City."
After hearing what Chen Xiao said, Shen Wei felt her nose was sore for some unknown reason and tears welled up in her eyes.
When they just graduated from high school, the two of them made an appointment to watch the maple leaves and climb the Great Wall together in Yanjing. They are already sophomores. Such a small wish has not been realized yet.
Shen Wei could only whisper: "I'll wait for you..."
"Weiwei, what are you doing? Let's go and eat." The roommate said hello, pulling Shen Wei out of her thoughts.
Chen Xiao returned to Jiangzhou and immediately threw himself into the laboratory.
Once the location of the gene is determined, it's easy to handle.
Following the instructions from the system, Chen Xiao cut out the part of the Listeria gene that uses electrons and assembled it into the corresponding parts of Rhodospirillum and Cyanobacteria.
The current equipment and conditions in Jiangzhou University's laboratory are certainly incomparable to those before Chen Xiaosheng's, but fortunately, there are still equipment for gene shearing.
Although the equipment is somewhat backward, it can be made up for by Chen Xiao's technology.
Chen Xiao's time was very tight. Even when Jiangzhou awarded Chen Xiao the "May 4th" Youth Medal, Chen Xiao didn't have time to go and asked Wang Xiang to lead it.
May 7th.
Jiangzhou University has a seven-day long holiday in accordance with regulations, and the entire campus is even emptier, and today is the last day of the May Day holiday.
In a BSL-3 laboratory.
Chen Xiao was furiously typing the experimental paper on the computer.
The part of the paper about animal experiments has entered the final stage.
Chen Xiao has not yet conducted experiments on mammals, which is the biggest drawback of experiments.
It’s not that Chen Xiao was unwilling to conduct experiments on mammals, but that when he did this part, he happened to be facing the May Day holiday.
The teachers in the Experimental Materials Management Section of the biology laboratory have all gone home for the holidays, and there are no white mice or rabbits in stock in the laboratory.
Of course Chen Xiao can buy some random animals in the market for experiments.
However, because the physical indicators of animals purchased on the market are uncertain and there is no way to form a standard control group, Chen Xiao is still willing to wait.
There is a black jar next to Chen Xiao's computer. The positive and negative poles of the jar are connected to the power supply. After the civilian power supply is transformed, a very weak current will be formed in the jar. This current cannot be used unless a very precise instrument is used.
, otherwise it cannot be perceived.
Such a weak current will not harm the creatures in the jar.
The inside of the jar is 100% distilled water, and there are hundreds of bugs swimming randomly in the water.
If you don't look carefully, you might think these are just ordinary insects in the water.
But if you look closely, you will find that these bugs in the water are actually fruit flies that can be found in daily life!
In this environment without any sunlight or oxygen.
This batch is fruit flies and has been living for 7 days.
Any biologist would be shocked to see this scene - the aerobic fruit fly lived in a completely anaerobic environment for a full 7 days.
This small group of ecological circles in the black jar completely breaks the basic common sense of biology and subverts certain facts that biologists have always believed in.
In the past hundreds of years of biological research, perhaps some biologists have explored the conditions under which aerobic organisms can live in an oxygen-free environment?
Many of them have tried many times and failed without exception.
But today, Chen Xiao achieved this goal by taking advantage of the unique symbiosis between different organisms.
After thinking about food and clothing, the fruit flies not only survived, but also mated and laid eggs on the fruit skin under the jar. However, these fruit flies did not realize that the next generation they reproduced and produced was completely different from themselves.
Even the eggs that are laid are lucky enough to hatch in the water.
The offspring of fruit flies that are born will suffocate and die immediately.
This was Chen Xiao's last experiment using fruit flies. The fruit flies were symbiotic with a mixed colony of improved Rhodospirillum and cyanobacteria. There is no way to naturally pass on the symbiotic characteristics to the next generation.
After typing the last word of the paper, Chen Xiao saved the document and closed the computer.
It has been more than two months since the Spring Festival until now.
Chen Xiao was in the laboratory almost day and night, sleeping on average less than 5 hours a day. Looking at it now, all the efforts were worth it.
Chen Xiao couldn't help crying and laughing and said: "We already have a system, so why torture me to do experiments? Wouldn't it be nice to just hand over the product to me?"
Complaints are complaints, work still needs to be done.
But tonight Chen Xiao can finally go home and have a good sleep.
He has already contacted the teacher who manages the experimental supplies, and he will be able to make some rabbits and mice from the laboratory early tomorrow morning.
As long as the last closed loop of the animal experiment is completed, the final part of the paper can be written.
Whether it's human trials or clinical applications, there's no need to worry about the rest, just give it time.
Moreover, Changtian Technology currently does not have a professional bioengineering team. Chen Xiao also needs to carefully plan the future development of Changtian Technology and establish more scientific research units.
Early the next morning, Chen Xiao came to Jiangzhou University.
He requested three rabbits and three white mice from the teacher who managed consumables in the biology laboratory to prepare for the laboratory later.
Unexpectedly, Fat Yang Kai was here. Yang Kai looked at Chen Xiao and asked quietly: "You also use rabbits? I heard that you have been working in the laboratory during this period. What did you tinker with?"
Chen Xiao said happily: "I didn't mess with anything, there were just some fruit flies."
Yang Kai didn't believe it, but he didn't ask any more questions.
Back in the laboratory, Chen Xiao's breathing was a little rapid.
After all, mammals and insects are completely different.
Mammals' demand for oxygen is tens of thousands or even hundreds of thousands of times that of insects, and their bodies also have complex and abundant capillaries.
How many bacterial colonies are needed, and how much oxygen must be metabolized per standard measurement of bacterial colonies per unit time, to meet the basic needs of mammals.
There is also the question of whether the oxygen produced is soluble in the blood, and what method should be used to combine it with hemoglobin.
The last point is whether the products of bacterial colony metabolism are harmful to the vital signs of mammals.
These answering systems have already been told to Chen Xiao, but the words remain the same.
Chen Xiao needs to experiment! Experiment! Experiment!
Just when Chen Xiao was about to anesthetize the first mouse, the phone rang.
