Main Text Chapter 381 A Paper That Will Change History

Previous page        Return to Catalog        Next page

    Chen Xiao was in a hurry in Yanjing. When he was at Xiaguo Academy of Sciences, he had been discussing some methods and contents of gene sequencing with Wu Wei's team in the genetic laboratory.

    After getting the sequencing results, he hurried back to Jiangzhou.

    Before leaving Jiangzhou, Chen Xiao called Shen Wei and informed her itinerary.

    Shen Wei was overjoyed when she learned that Chen Xiao was actually in Yanjing. 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 went to Xia Guo Academy of Sciences to do some private affairs. Next time I come to Yanjing, I will definitely climb the Great Wall with you and see the Forbidden City."

    After hearing Chen Xiao's words, Shen Wei didn't know why, but her nose felt sore, and tears rolled in her eyes.

    When they just graduated from high school, the two made an appointment to see the maple leaves and climb the Great Wall together in Yanjing. They are both sophomores. Such a small wish has not been realized so far.

    Shen Wei could only whisper: "I'll wait for you"

    "Wei Wei, why are you in a daze, let's go, it's time to eat." The roommate greeted, and then pulled Shen Wei out of her thoughts.

    Chen Xiao, who returned to Jiangzhou, immediately threw himself into the laboratory.

    Once the location of the gene is determined, it's easy to handle.

    According to the method informed by the system, Chen Xiao excised the part of the gene that uses electrons in Listeria, and assembled it into the corresponding parts of Rhodospirillum and Cyanobacteria.

    At present, the equipment and conditions of Jiangzhou University's laboratory are definitely incomparable with those before Chen Xiao's rebirth, but fortunately, the equipment for gene cutting is still available.

    Although the equipment is a bit behind, it can be made up for with Chen Xiao's technology.

    Chen Xiao's time was very tight, even if Jiangzhou awarded Chen Xiao the "May 4th" Youth Medal, Chen Xiao didn't have time to go, but let Wang Xiang lead it.

    May 7th.

    Jiangzhou University has a 7-day long holiday according to regulations, and the entire campus is even more empty, and today is the last day of the May Day holiday.

    In the bsl-3 laboratory.

    Chen Xiao frantically typed on the experimental papers on the computer.

    The part of the thesis about animal experiments has entered the final stage.

    Chen Xiao has not yet conducted experiments with mammals, which is the biggest drawback of the experiment.

    It wasn't that Chen Xiao was unwilling to conduct experiments with mammals, but that when he did this part, he happened to be facing the May Day holiday.

    The teachers of the Experimental Materials Management Department of the Biology Laboratory have all gone home on vacation, and the laboratory does not have any white mice or rabbits in stock.

    Of course, Chen Xiao can buy some animals at will in the market for experiments.

    However, because the physical indicators of the animals purchased in the market are uncertain, there is no way to form a standard control group, so Chen Xiao is still willing to wait.

    There is a black pot next to Chen Xiao's computer. The positive and negative poles of the pot are connected to the power supply. After the civilian power supply is transformed, a very weak current will be formed in the pot.  , otherwise it cannot be perceived.

    Such a weak current will not harm the creatures in the jar.

    Inside the jar is 100% distilled water, and there are hundreds of worms swimming around in the water.

    If you don't look carefully, you may think that these are just ordinary insects in the water.

    But if you look carefully, you will find that these bugs in the water are actually fruit flies that can be found at any time in life!

    In such an environment without any sunlight and oxygen.

    This batch is fruit flies, which have lived for 7 days.

    Any biologist will be shocked to see this scene-the good oxygen organism Drosophila lived in a completely anaerobic environment for 7 days.

    This handful of ecological circles in the black jar completely broke the basic common sense of biology and overturned a certain fact that biologists have always believed in.

    In the past hundreds of years of biological research history, some biologists may have discussed under what conditions aerobic organisms can live in an oxygen-free environment?

    Many of them have tried many times and ended in failure without exception.

    But today, Chen Xiao achieved this goal by using the special symbiosis between different creatures.

    Thinking about food and clothing, the fruit flies not only survived, but also mated and laid eggs on the fruit skin under the jar, but these fruit flies did not find that the next generation they reproduced and produced was completely different from themselves.

    Even if the eggs produced are lucky enough to hatch in water.

    bornThe progeny of fruit flies will immediately suffocate to death.

    This is Chen Xiao's last experiment using fruit flies. The fruit flies that symbiosis the mixed colonies of improved Rhodospirilla and cyanobacteria cannot naturally pass on the characteristics of symbiosis to the next generation.

    After typing the last word of the thesis, Chen Xiao saved the document and closed the computer.

    From the Spring Festival to the present, more than two months.

    Chen Xiao is in the laboratory almost day and night, and the average sleep time is less than 5 hours a day. Looking at it now, all the efforts are worthwhile.

    Chen Xiao couldn't help crying and laughing and said: "Obviously there is a system, why torture me to do experiments? Isn't it good 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 consumables, and he will be able to fiddle with a few rabbits and mice from the laboratory early tomorrow morning.

    As long as the last closed loop of the animal experiment is completed, the last part of the thesis can be written.

    Whether the rest is human trials or clinical applications, don't worry about it, just give it to time.

    Besides, Changtian Technology does not yet have a professional bioengineering team. Chen Xiao still needs to make a good plan for the future development of Changtian Technology and set up some more scientific research units.

    Early the next morning, Chen Xiao came to Jiangzhou University.

    He applied for 3 rabbits and 3 mice to the teacher who manages consumables in the biology laboratory, and prepared to wait in the laboratory.

    Unexpectedly, the fat man Yang Kai would also be here. Yang Kai looked at Chen Xiao and quietly asked, "You also use rabbits? I heard that you have been working in the laboratory all this time. What exactly did you come up with?"

    Chen Xiao said cheerfully: "I didn't mess with anything, but there were some fruit flies."

    Yang Kai didn't believe it, but he didn't ask too much.

    Back in the laboratory, Chen Xiao's breathing was a little short.

    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 rich capillaries.

    ?How many colonies are needed, and how much oxygen must be metabolized per unit time for each standard metered colony to meet the basic needs of mammals.

    There is also 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.

    The system has already told Chen Xiao these answers, but it's still the same sentence.

    Chen Xiao needs to experiment!  experiment!  experiment!

    Just when Chen Xiao was about to anesthetize the first mouse, the phone rang.  (
