I make a popular science video and all the emperors learn from it!

【With the development of science and technology, human scientists have begun to develop more and more realistic】

【Human organs with increasingly stronger applicability】

【Some scientists even predict that in the near future, almost all organs in the human body can be replaced with artificial organs.】

【By then, human lifespan will be further extended and average life expectancy will also be greatly increased.~】

【Here are ten types of artificial organ-organ technologies:】

【10. Ultra-sensitive electronic skin】

【Skin works hard to wrap us up and protect our entire body】

【Therefore, it has also become the most vulnerable organ】

【When skin is burned or cut, your quickest option is to transplant a part from another part of the body】

【However, thanks to research by scientists at Stanford University, a material that can effectively replace human skin will soon be available】

【Zhenan Baohas of Stanford University has developed a super-elastic, super-resistant and super-sensitive material that can serve as the basis for the future development of artificial skin.】

【Biochemical skin has been studied before, but Baohas' material is more sensitive than previously developed】

【It contains organic conversion substances and a layer of elastic material to ensure its ductility without being damaged. In addition, the material comes with a series of solar cells that can be charged automatically】

【9. A beating heart in a petri dish】

【Scientists have long studied the potential of stem cells to differentiate into heart tissue, an effort that reached a major milestone this year when they created heart tissue that can beat on its own.】

【University of Pittsburgh research team grows MCPs, specialized cells that act as cardiovascular tissue drivers, from stem cells derived from skin】

【They placed the cells on a 3-D scaffold that could sustain mouse hearts.】

【Within 20 days, the new heart starts beating at a rate of 40 to 50 beats per minute.】

【Although this heart is too weak to actually pump blood, this cell tissue has huge potential in repairing injured heart muscle.】

【It is very likely to replace expensive mechanical hearts in the future.】

【8. Tactile artificial hands】

【Today's prosthetic hands have almost no other functions besides the shape of the hand.】

【Sure, these prosthetic hands can hold things and maintain balance, but they lack one of the most important functions of the human hand - touch.】

【When a person with a prosthetic hand touches an object, he or she cannot judge the object without seeing it with his or her eyes.】

【A team of researchers at the University of Chicago has solved this problem by creating a prosthetic hand that can transmit signals to the brain.】

【They used monkeys as test subjects to study the animal's brain response to touch signals.】

【When equipped with brain-stimulating prosthetic hands, the monkeys reacted as if they were physically touching the object】

【Programming these similar signals into prosthetic limbs will give amputees a completely different prosthetic limb from previously developed products.】

【7. Thought-controlled bionic legs】

【Although bionic legs are a huge boon for amputees】

【However, they lack real neural connections with the human body, making walking on bionic legs very troublesome and tiring.】

【But last year, Xiatu resident Zac Vawter was fitted with the world's first thought-controlled leg, a bionic limb that receives signals directly from his brain】

【This technology has been used in weapons before, but applying it to bionic legs would be more complicated】

【Vawter uses bionic legs to climb 103 stairs in a tall building】

【But the designers of the bionic leg are still trying to improve its performance】

【In order to make it suitable for daily life, designers must make it lighter and thinner. Its derivative (inflatable bionic leg) can meet the Army's phased goal for bionic legs - walking 10,000 steps without charging.】

【6. Miniature human brain】

【If you love survival, brain death is a bad thing】

【And if you want to replace it with a spare brain, you won't find it】

【Sure, maybe one day we'll be able to put a brain inside the skull, but the brain is not like any other organ】

【It holds all your thoughts and memories】

【People could put a new brain in your head, but you still wouldn't exist, so the idea of ​​an artificial brain seems ridiculous.】

【But that hasn't stopped scientists from developing artificial brains in the lab】

【Odili scientists have successfully created a brain equivalent to that of a nine-week-old baby, starting only with stem cells】

【Currently, these brains are only about the size of peas and cannot think. What prevents these experiments from developing into fully functional brains is that they have no blood supply.】

【Although these brains have not entered anyone's body, they provide raw materials for the Academy of Sciences to study brain diseases.】

【5.3D printed ears】

【It’s been decades since we developed the technology to artificially record sound, but artificial implants have changed nothing in the ear.】

【You might think that the chunks of flesh growing on either side of the head are easily replaceable】

【Because they are just skin and cartilage, not complex organs】

【In fact, scientists haven't done a very good job of making prosthetic ears, and traditional replacement ears look or feel like plastic toys.】

【But recently, researchers have proposed a new method that can create elastic, real ears using real cells.】

【These cells, derived from mice and cows, can form collagen gels that can be molded into any mold.】

【When placed in a 3D printed ear model, the gel formed a prosthetic ear within an hour.】

【The artificial ear only needs to be grown in nutrients for a few days before being transplanted to the subject.】

【These artificial ears are great news for those who have suffered ear injuries or whose ears have stagnated development, that is, microtia.】

【4. Smell the nose of disease】

【Scientists are deeply invested in giving human organs their original capabilities】

【But why limit it to this??】

【When Illinois researchers set out to build a device that relied on smell to identify chemicals, they weren't satisfied with just improving the sensitivity of the human nose.】

【Instead, they developed a prosthetic nose that relies on the smell of bacteria to identify and diagnose certain diseases. 】(To read exciting novels, go to Feilu Novel Network!)

【The product doesn’t look much like a nose】

【Rather, it is a bottle filled with nutrient liquid for cultivating bacteria.】

【But give this"nose" a blood sample and let it smell it for a while, and the spots on the bottle will change color to indicate the type of bacteria it has identified.】

【......】

【Attachment: Sample pictures*7. 】

The ancients were convinced after reading it.

Those who had doubts about artificial organs before have nothing to say now.

"Artificial leather, artificial hands and feet, how can you even create a heart and brain! ?"

"It's a bit infiltrative. I'm really afraid that future generations will wear artificial things all over their bodies. Isn't that still a human being? ?"

"Oh, I don’t dare to write fairy tales like this. If something is broken on the body, surgery can replace it with a new one."

"......"

Qin Dynasty.

Ying Zheng's scalp was numb when he saw it!

"The widow said, why do descendants always like to use a knife to perform surgery? It turns out that there are organs that can be replaced."

He looked back and found that the principle of the operation was too simple.

Just like repairing something, if any part is damaged, repair it if it can be repaired.

It doesn't matter if it can't be repaired, just replace it with a new one.

He quickly realized that the light curtain He said,"When artificial organ technology matures, human lifespan will be increased again."This sentence is very reliable!

Isn't it true? As long as the brain is not damaged, most organs can be replaced with new ones!

Ying Zheng's eyes suddenly widened.

He exclaimed:"Isn't this just immortality!! ?"

Han Dynasty.

Liu Che no longer dared to underestimate the"evil magic" of the light curtain.

Before watching it, he sneered.

After watching it, he was completely convinced and wanted to[]

"There is actually this method that can make people live longer!"

The combination of organ replacement surgery and artificial organ technology allowed him to see a brand new way of longevity.

Although it may not necessarily make people immortal, it can certainly significantly increase life span.

But Liu Che was not dazzled by the surprise.

He remembered transplantation Other people's organs will have rejection reactions.

In the Tang Dynasty,

Wu Zetian was directly envious.

She really wanted to replace all the aging organs in her body with new ones, except her brain.

In this way, wouldn't she become young again? ?

And the organs waiting for replacement will age again, and then a batch of new ones will be replaced.

If the cycle repeats, there is hope for immortality!
