The spillover effect of a large number of scientific research results is rapidly affecting all areas of Homo sapiens.

For example, the fixed cable of the stratospheric railway, which has been woven from composite alloy wires before, is too heavy in weight and relatively reluctant in strength.

Now, with the emergence of carbon nanotube multilayer casing technology, which can produce a single line of 20~30 kilometers, the air rail group has rapidly updated.

Cables made of carbon nanotubes with multi-layer sleeves weigh only 3.4% of the weight of conventional alloy cables, but the strength has increased by about 48 times.

The reduction of the weight of the cable has increased the effective carrying capacity of the stratospheric railway a lot.

In addition, the application of carbon nanotubes in other fields is not a few, and the application of this technology greatly reduces the disadvantages of metal cables.

Of course, carbon nanotubes are not perfect things, such as air erosion, cosmic ray destruction, have seriously affected the service life of carbon nanotubes, which is a fatal problem that is difficult to avoid carbon materials.

However, the problem of service life can also be solved.

For example, the anti-radiation gel researched by Li Qingye in the Pangea realm, after secondary processing, can be used as the outer coating of many materials, and its protection effect against cosmic rays is very good, except for a few high-energy neutrons and Gamma rays, other cosmic rays have no way to penetrate this gel.

Of course, this anti-radiation gel is not once and for all, it also has a service life, if it is exposed to the stratosphere, the 3 mm thickness of the gel curing layer, it can only last about 17 months.

In this regard, the air rail group is not too disappointed, after all, it can resist radiation and is a lightweight material, so don't ask too much.

The lead plate composite layer, which can also resist radiation, can be used for decades, but the problem is that the lead plate is too heavy.

Therefore, the air rail group chose the anti-radiation gel, which is often maintained and repainted in the future.

Compared with replacing carbon nanotube cables, which are not cheap, frequent application of anti-radiation gel is the most cost-effective solution.

……

Pangea – Earthquake Zone.

Li Qingye spent a week reading the annual reports of various departments of the company, and then arranged some work.

And he himself came to the earthquake zone.

This area had previously been used as a backup research area, but was recently transformed into a bioinformatics decoding center.

Li Qingye is discussing some things with the heads of several earthquake areas, such as how to apply genetic inverse decoding technology to obtain information about the ancient times of the earth.

Zhang Zaiwen, a paleontology major, said excitedly: "Chairman, this technology is really powerful, we chose crocodiles as the target of decoding, and obtained a lot of pictures of ancient times." ”

Li Qingye looked at the very weird restoration picture: "Is this the perspective of a crocodile?" ”

"Yes." Zhang Zaiwen nodded.

Since crocodiles' sense of sight and hearing is different from that of humans, the images and sounds that have been passed down from their genes can be very strange when viewed from a human perspective.

For example, some animals may not be able to see the colors that humans can see, and some animals may not be able to observe the colors that humans can see.

For example, the vast majority of mammals are red-green color blind.

Many people think that tigers' fur is very conspicuous, and that is because humans are generally not red-green color blind, but in the eyes of other mammals, the color of tiger's fur is a very hidden environmental camouflage.

The visual organs of insects and arthropods are often very specialized, such as mantis shrimp, which can see more than an order of magnitude more than humans.

Zhang Zaiwen patted the biocomputer on the side: "We are currently trying to solve the problem of viewing angle, and turn the original image into a picture that can be easily viewed by humans as much as possible." ”

"What is the farthest genetic memory that can be traced at present?"

"Crocodiles can be up to 270 million years old, and their family is a living fossil, but the genetic memory is very fragmentary."

Li Qingye is clear about this, after he modified his genes, the ancestral memory ability he obtained was like this.

Genes can record the living memories of organisms, but as genes continue to iterate, each iteration will lose a part of the ancestral memory, which is one of the costs of evolution.

And Li Qingye also saw the idea of Zhang Zaiwen's team, they are now using crocodiles as materials for extracting ancient information, the reason is that the mutation of crocodiles is not big, and they are not much different from their ancestors hundreds of millions of years ago.

This is a relatively rare group of living fossils among modern animals.

If you choose other animals, such as the common pheasant, whose ancestors were dinosaurs, the difference between the two is too great, which means that the pheasant has produced a relatively large mutation in the process of evolution.

And this mutation often seriously disrupts the information transmission of ancestral memories.

Li Qingye is very unclear about what happened to his ancestors hundreds of thousands of years ago, because human beings have had several major mutations in the process of evolution.

"Although the memories from hundreds of millions of years ago are very fragmentary, we have gained a lot of important information, such as climate change in ancient Africa, and changes in latitude and longitude......"

Zhang Zaiwen said as he called up a simulated earth model, determined the age through genetic iteration, and entered the crocodile genetic memory relative to the age into the supercomputer, and then started the deduction.

Soon the evolution of the simulated earth will be in full swing.

Including plate movements, volcanic earthquakes, seasonal changes, etc., in Africa, it is analyzed little by little.

Although this is only a biological perspective of a drop in the ocean, as long as enough animal ancestral memories are collected in the future, it is completely possible to piece together a relatively clear evolution of the ancient earth.

"Not bad." Li Qingye sees a very clear evolution of the earth's climate.

In particular, the climate models of the last 3 million years are basically very clear.

This is not the same as studying geology, and the accuracy of the data analyzed by this genetic memory can be accurate to the year, or even the month and day.

As long as we get closer to modern times, the clearer the information about the genetic memory of animals, and it is natural to judge the evolution of climate.

Li Qingye inspected here for a while, and then went back to Ze District to work on new projects.

His new project has something to do with genetic memory.

However, the genetic memory of this project is not analyzed, but entered.

Li Qingye hopes that by entering knowledge into genes, and then activating hidden genetic memories at a specific stage of development, the purpose of inheritance can be achieved.

The reason why we want to carry out this project is that the human knowledge base is getting bigger and bigger, and even if there is a biochip, it will take several years to complete the study of a university subject.

The increasingly large knowledge base and long learning time will make the speed of human development decline again.

Although the new human beings at this stage have not yet experienced a decline in the development rate, this situation will inevitably appear in the future.

When there is so much knowledge that it is impossible to learn, it is the time when the development of new human beings enters a bottleneck period.

Li Qingye is taking precautions, he plans to use the power of genes to enter knowledge into genes, and then let human beings directly inherit the knowledge in genetic memory after completing physical development, so as to break the bottleneck of development.
