The rise of nanometers

After the speech, he talked with a group of outstanding student representatives for more than half an hour before ending the trip.

Huang Xiuyuan stood above the hemispheric campus of the College of Engineering. This is a very huge tower-shaped building that overlooks the entire Hulunbuir Lake.

The weather was bitterly cold, and the Siberian cold wind blew in from the northwest and solidified the lake surface.

In fact, this is one of the reasons why the buildings of Suiren University adopt a hemispherical design. This year, the water area of ​​Hulunbuir Lake has increased by about 17%.

In the past few years, the water area of ​​Hulunbuir Lake has increased by about 41%, and has begun to return to a level close to historical highs.

Of course, this lake has almost caught up with the size of Hulun Lake.

Huang Xiuyuan has read relevant data. Due to the inflow of large amounts of fresh water resources, the annual precipitation in Mongolia, Mobei, and northwest China has shown an increasing trend in recent years.

This has led to the gradual expansion of the area of ​​many lakes, and the gradual expansion of humid and semi-humid zones from the north to the west. Especially in the Tarim Basin, the transformation speed is very fast.

In fact, this is related to the topography of the Tarim Basin. Since it is surrounded by high mountains and plateaus, it effectively blocks the flow of water vapor to other areas. When the local water resources increase, the amount of water evaporated into the atmosphere also increases, which in turn leads to an increase in local precipitation. .

Huang Xiuyuan's next stop is a secret base deep in the Taklimakan Desert.

He took the transparent elevator downstairs, looked at the vast white sky and earth, and suddenly felt a sense of independence from the world.

The stand-in robot returned to the convoy and got into the minibus, then walked along the viaduct and left Suiren University.

Looking down from the viaducts, you will find that these viaducts are much higher than ordinary viaducts. In fact, this is a design made in advance, because Bell Lake will definitely continue to expand in area in the future, and Suiren University will definitely be surrounded by the lake.

Therefore, the viaduct prevents the lake water from rising in advance and avoids reconstruction in the future.

This is also something that needs to be considered for many buildings near lakes, otherwise the buildings may turn into islands in the water during a heavy rainstorm.

Huang Xiuyuan exited this stand-in robot and logged into another stand-in robot.

This stand-in robot woke up directly in the storage cabin deep underground in the secret base. After he entered the password, the storage cabin door opened to the left and right.

Picking up the mobile phone and tablet that had been stored aside for a long time, he entered a number: "...Xingyang, come and pick me up! I'm in the underground storage room."

A rich male voice immediately came from the opposite side: "Okay, Academician Huang."

Ten minutes later, five staff members in blue uniforms opened the door to the preservation room. The middle-aged man with a Chinese character in the lead said with a smile: "Welcome Academician Huang to come and give guidance."

"Take me up! Tell me about the situation in the base." Huang Xiuyuan said while checking the information in the base on the tablet.

This base is very closed. He has to use a stand-in robot to enter, and he can only use the highest-level optical fiber intranet.

After walking out of the underground area, you come to the ground building area. The design of the ground building here is similar to the hemispherical building of Suiren University.

However, the information released here is an artificial ecosystem research base. The hemispherical buildings on the surface of the base are the artificial ecosystem.

This project was established in July 2012. Currently, three experimental ecosystems have been established. The main purpose is to study how to create an artificial ecosystem suitable for human survival in outer space.

But the artificial ecosphere is only the surface project of the base. Its real core task is to study the Mars fungus previously obtained from the desert island base.

After layers of disinfection, Huang Xiuyuan and base director Lin Xingyang finally arrived at the core laboratory.

Dr. Zhou Jingwei, who is responsible for the overall work of biochemical research, saw Huang Xiuyuan walking in with a rare smile on his serious expression: "Academician Huang, long time no see."

The two shook hands, and Huang Xiuyuan said, "I took a look at the research progress chart. Your research is progressing well."

Zhou Jingwei pointed to the double windows: "Academician Huang, this is a small simulated ecological circle. I put in a dose of Yinghuo fungus yesterday."

The Yinghuo fungus is the Mars fungus. Since it is being studied in China, the Western-style translation name of Mars was eliminated, and the domestically familiar Yinghuo fungus was used as the name.

Huang Xiuyuan looked through the window and saw the inside of this small simulated ecological circle.

Many animals and plants have mutated to varying degrees, but most of these mutations are malignant mutations. The creatures in this small ecological circle have all kinds of strange shapes.

Zhou Jingwei continued to explain: "Academician Huang, your prediction is correct. Although the infection ability and toxicity of the fluorescent fungus are extremely strong, it is also gradually adapting to the ecological environment of Blue Star. After dozens of ecological adaptation screenings, , we obtained a batch of strains with relatively weak toxicity."

"Normal, this is the way for microorganisms to survive. They and their hosts are always adapting to each other." Huang Xiuyuan opened the monitoring system next to the window, and a more detailed picture could be seen above.

The vines that turned into carnivorous plants, the turtles whose surfaces were covered with blue scales, and the mice whose surfaces didn't change much were all parasitized by fluorescent fungi.

"Jingwei, to what extent have you studied the effects of Yinghuo on mammals?"

Zhou Jingwei explained: "Currently, we have tested 15 times on macaques and found that during the process of parasitism in primates, phosphorus will imitate some functions of somatic cells and then deceive the immune system, thus persisting in the body for a long time."

Then he introduced some specific situations.

The fluorescent fungus is not only very toxic. Once it enters the body of a mammal, it will imitate parasitism and then produce blue mycelium to cover the surface of the organism.

In fact, these blue hyphae are not really blue, but a problem with their own structure. Under the microscope, the hyphae of fluorescent fungi show a special nanostructure, which gives them some characteristics of water bodies. Improve its own absorption efficiency of light energy.

Among them, the blue light band, which is the one with the lowest absorption rate by fluorescent fungi, is almost all reflected, so it appears sea blue.

In fact, fluorescent fungus is an anaerobic bacterium, similar to sulfur bacteria, that can perform photosynthesis, using the abundant potassium sulfate and relatively large amounts of carbon dioxide on Mars as raw materials for photosynthesis.

However, as time goes by, through the stimulation of the Blue Star environment, the glowing fungus is gradually changing some of its characteristics.

Fluorescent fungi will affect Blue Star organisms and cause Blue Star organisms to mutate. Through photosynthesis, they secrete a special protein, a minimalist protein similar to prions.

Zhou Jingwei named the protein "gene chimeric protein". As the name suggests, this special protein can be embedded in biological gene sequences.

This behavior of forcibly chimerizing into the host gene sequence will naturally cause crazy mutations in the host gene.

Biological genes are like mathematical formulas, which are the magical crystallization of the natural environment over hundreds of millions of years. If a large number of numbers are inserted into these formulas, the calculation results will naturally change.

This is the core factor that causes fluorescent fungi to cause host gene mutations.
