Chapter 549 Quick Update
The spillover effects of a large number of scientific research results are rapidly affecting all areas of the company.
For example, the fixed cables of the stratospheric railway have always been woven from composite alloy wires. They are too heavy and their strength is relatively weak.
Now with the emergence of carbon nanotube multi-layer casing technology, which can produce single lines of 20 to 30 kilometers, the Skytie Group has rapidly upgraded.
The cable made of carbon nanotubes with multi-layer sheaths weighs only 3.4% of the previous alloy cable, but its strength is increased by about 48 times.
The reduction in cable weight has greatly increased the effective carrying capacity of the stratospheric railway.
In addition, carbon nanotubes are also widely used in other fields. The application of this technology has greatly reduced the disadvantages of metal cables.
Of course, carbon nanotubes are not perfect. For example, erosion by air and damage by cosmic rays seriously affect the service life of carbon nanotubes. This is a fatal problem that is difficult to avoid for carbon materials.
However, the service life problem can also be solved.
For example, the anti-radiation gel developed by Li Qingye in the Pangu Realm can be used as an outer coating for many materials after secondary processing. It has an excellent protection against cosmic rays. Except for a few high-energy neutrons and gamma rays, other cosmic rays cannot penetrate this gel.
Of course, this anti-radiation gel is not a one-time solution. It also has a service life. If exposed to the stratosphere, a 3 mm thick gel solidified layer can only last about 17 months.
The Air Rail Group was not too disappointed about this. After all, there is no need to have too high expectations for the material, which is radiation-resistant and lightweight.
The lead plate composite layer, which is also radiation-resistant, can be used for decades, but the problem is that the lead plate is too heavy.
Therefore, the SkyRail Group chose anti-radiation gel, which can be maintained and repainted frequently in the future.
Compared to replacing expensive carbon nanotube cables, regular application of anti-radiation gel is the most cost-effective option.
…
Pangu Realm - Earthquake Zone.
Li Qingye spent a week reviewing the annual reports of each department of the company and then assigned some work.
He himself came to the earthquake zone.
This area had previously been used as a backup scientific research area, and was recently transformed into a bioinformation decoding center.
Li Qingye was discussing some things with the heads of several earthquake zones, such as how to apply genetic reverse decoding technology to obtain information about the ancient Earth.
Zhang Zaiwen, who majored in paleontology, said excitedly: "Chairman, this technology is really amazing. We chose crocodiles as the target for decoding and obtained a lot of images from ancient times."
Li Qingye looked at the strange restored image and asked, "Is this the crocodile's perspective?"
"Yes." Zhang Zaiwen nodded.
Because crocodiles' vision and hearing are different from humans', the images and sounds hidden in their genes and passed down through generations appear very strange when observed from a human perspective.
For example, some colors that humans can see may not be visible to some animals, and some colors that animals can see may not be observed by humans.
For example, most mammals are red-green color blind.
Many people think that tiger's fur is very conspicuous, that's 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 concealed environmental camouflage color.
The visual organs of insects and arthropods are often highly specialized. For example, mantis shrimps can see colors that are more than an order of magnitude richer than humans.
Zhang Zaiwen patted the biological computer next to him and said, "We are currently trying to solve the problem of perspective and transform the original image into a picture that humans can easily browse as much as possible."
"What is the furthest period of genetic memory that can ?"
"Crocodile families can reach 270 million years ago. Their family is a living fossil, but their genetic memory is very fragmented."
Li Qingye knew this very well. This was the situation when he gained the ability to remember his ancestors after modifying his own genes.
Genes can record the life memories of organisms, but as genes continue to iterate, each iteration will lose a portion of ancestral memory. This is one of the costs of evolution.
Li Qingye also saw the idea of Zhang Zaiwen's team. They now use crocodiles as materials for extracting ancient information because crocodiles do not mutate much and are not much different from their ancestors hundreds of millions of years ago.
This is a relatively rare living fossil group among modern animals.
If we choose other animals, such as the common pheasant, their ancestors are dinosaurs, and the differences between the two are too great, which means that relatively large mutations occurred during the evolution of pheasants.
Such mutations often seriously damage the inheritance of information from ancestral memories.
Li Qingye is very vague about what happened to his ancestors hundreds of thousands of years ago, because humans have undergone several major mutations during the process of evolution.
"Although the memory of hundreds of millions of years ago is very fragmentary, we still obtained a lot of important information, such as climate change in ancient Africa and changes in longitude and latitude..."
As Zhang Zaiwen spoke, he called up a simulated earth model, determined the age through genetic iteration, recorded the crocodile genetic memory corresponding to that age into the supercomputer, and then started the deduction.
Soon the simulated Earth underwent tremendous changes.
Including Africa's plate movement, volcanic earthquakes, changes in seasons, etc., all were analyzed bit by bit.
The vicissitudes of the earth are displayed before everyone one by one. Although this is only a drop in the ocean of biological perspectives, in the future, as long as enough memories of animal ancestors are collected, it is entirely possible to piece together a relatively clear evolution process of the ancient earth.
"That's right." Li Qingye saw the evolution of the earth's climate very clearly.
In particular, the climate models over the past 3 million years have become very clear.
This is different from geological research. The data analyzed from genetic memory can be accurate to the year, or even month and day.
The closer we are to the present, the clearer the information in the animals' genetic memory will be, and we can naturally judge the evolution of the climate.
Li Qingye inspected here for a while and then went back to Ze District to work on a new project.
His new project has to do with genetic memory.
However, the genetic memory of this project is not analyzed, but recorded.
Li Qingye hopes to achieve the purpose of inheritance by recording knowledge into genes and then activating hidden genetic memories at specific developmental stages.
The reason for carrying out this project is that the human knowledge base is becoming increasingly large. Even with biochips, it will take several years to complete the study of a major subject.
The increasingly large knowledge base and the long learning time will cause the speed of human development to slow down again.
Although the new humans at this stage have not yet seen a slowdown in their development, this situation is bound to occur in the future.
When there is too much knowledge to learn, the development of new humans enters a bottleneck period.
Li Qingye is preparing for a rainy day. He plans to use the power of genes to record knowledge into genes, and then let humans directly inherit the knowledge in genetic memory after completing their physical development, thus breaking the development bottleneck.
