Homo sapiens.

Chapter 549 Quick Update

The spillover effect of a large number of scientific research achievements is rapidly affecting various fields of Homo Sapiens.

For example, the fixed cables of the stratospheric railway, which have been braided with composite alloy wires before, are too heavy and relatively weak in strength.

Now with the emergence of carbon nanotube multi-layer casing technology, after a single line of 20 to 30 kilometers can be produced, the Air Railway Group is rapidly upgrading.

The cable made of carbon nanotubes with multi-layer casing is only 3.4% of the weight of the previous alloy cable, but the strength has increased by about 48 times.

The reduction in the weight of the cables has greatly improved the effective bearing capacity of the stratospheric railway.

In addition, there are many applications of carbon nanotubes in other fields. The application of this technology greatly reduces the disadvantages of metal cables.

Of course, carbon nanotubes are not perfect. For example, the erosion of air and the destruction of cosmic rays have seriously affected the service life of carbon nanotubes. This is a fatal problem that carbon materials cannot avoid.

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

For example, the anti-radiation gel developed by Li Qingye in the Pangu world, after secondary processing, it can be used as the outer coating of many materials, and its protective effect on cosmic rays is very good, except for a few high-energy neutrons and gamma rays, No other cosmic rays can 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, a 3 mm thick gel solidified layer can only last for about 17 months.

The Air Rail Group is not too disappointed about this. After all, it is radiation-resistant and lightweight, so don't expect too much.

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

Therefore, the Air Railway Group chose anti-radiation gel, and at worst, it will be maintained and repainted frequently in the future.

Compared with replacing the expensive carbon nanotube cables, it is the most cost-effective solution to frequently apply anti-radiation gel.

……

Pangu Realm - earthquake zone.

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

And he himself came to the earthquake zone.

This area has been used as a spare scientific research area before, and it was transformed into a biological information decoding center some time ago.

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

Zhang Zaiwen, who majored in paleontology, said excitedly: "Chairman, this technology is really powerful. We chose crocodiles as the target of decoding and obtained a lot of images from ancient times."

Li Qingye looked at the very weird restoration screen: "Is this the crocodile's perspective?"

"Yes." Zhang Zaiwen nodded.

Since the vision and hearing of crocodiles are different from those of humans, the pictures and sounds they inherit are hidden in their genes, and it will be very weird to observe from a human perspective.

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

For example, most mammals are red-green color blind.

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

The visual organs of insects and arthropods are often very specialized. For example, mantis shrimps can see more colors than humans by more than an order of magnitude.

Zhang Zaiwen patted the biological computer on the side: "We are currently trying to find a way to solve the problem of perspective, and try to convert the original image into a picture that humans can easily browse."

"The genetic memory that can be traced at present, what is the furthest period?"

"Crocodiles can reach 2.7 million years ago. Their family is a living fossil, but the genetic memory is very fragmented."

Li Qingye is very clear about this. After modifying his own genes, he obtained the ability to remember the ancestors. This is the case.

Genes can record the memory of organisms during life, but with the continuous iteration of genes, a part of ancestral memory will be lost with each iteration, which is one of the costs of evolution.

And Li Qingye also saw the thinking of Zhang Zaiwen's team. They now use crocodiles as materials for extracting ancient information. The reason is that the mutations of crocodiles are not large, 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 common pheasants, their ancestors are dinosaurs, and the difference between the two is too great, which means that during the evolution of pheasants, relatively large mutations have occurred.

And such mutations often severely disrupt the information transmission of ancestral memories.

Li Qingye is very vague about what happened to his ancestors 10 years ago, because humans have undergone several major mutations during the evolution process.

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

As Zhang Zaiwen said, he called up a simulated earth model, and entered the age of the crocodile genetic memory corresponding to the age into the supercomputer through genetic iteration to determine the age, and then started the deduction.

Soon the simulated earth will experience vicissitudes of life.

Including plate movements in Africa, volcanic earthquakes, and seasonal changes, etc., were analyzed bit by bit.

The vicissitudes of the earth are displayed in front of everyone one by one. Although this is just a biological perspective of a drop in the ocean, as long as enough memories of animal ancestors are collected in the future, a relatively clear evolution of the ancient earth can be pieced together.

"Not bad." Li Qingye saw a very clear evolution of the Earth's climate.

In particular, the climate models for the past 300 million years are basically very clear.

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

As long as it is closer to modern times, the information of the animal's genetic memory will be clearer, and the evolution of the climate can naturally be judged.

Li Qingye inspected here for a while, then went back to the swamp area to start a new project.

His new project has to do with genetic memory.

However, the genetic memory of this project is not an analysis, but an entry.

Li Qingye hopes to achieve the purpose of inheritance by entering knowledge into genes, and then activating hidden genetic memories at specific developmental stages.

The reason for this project is that the knowledge base of human beings is getting bigger and bigger. Even with biochips, it will take several years to complete the study of a major subject.

The ever-increasing knowledge base and the long learning time will cause the speed of human development to decline again.

Although the new human beings at this stage have not experienced a decline in their development speed, this situation will inevitably occur in the future.

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

Li Qingye is planning for a rainy day. He intends to use the power of genes to record knowledge into genes, and then allow human beings to directly inherit the knowledge in genetic memory after completing physical development, thereby breaking the development bottleneck.
