Closing New York’s 42nd Street?

Throughout May, New Yorkers discussed this matter the most. (1_1)

In the eyes of many people, the blockade of 42nd Street was simply a catastrophic event!

Some newspapers were already laughing at this time: jokes brought about by computers, absurd rational assumptions...

Wait, these reports are endless.

But some people feel that this is really possible!

The examples given by Catherine were so vivid. After hearing Catherine's examples, many people began to think.

For Catherine, the most exciting thing throughout May was another thing. That is that "Death Fantasy" will be released next month.

Although Brother Cheng Long's "Police Story" was canceled by Catherine again, this did not affect Catherine's side.

In the Hive Laboratory, as the limb functions are improved, the puppet's next plan begins.

——Organ-on-a-chip.

"Organ chips" are not simulators that use silicon electronic chips to simulate human organs, but biochips containing real human cells.

"Lung chip", "heart chip", "gut chip", etc. are all available.

Mechanization and electronics mean that the control of the puppet will be easier. The closer it is to the human body, the more difficult it will be to control.

Because Catherine doesn't have to worry about ethics and can develop life sciences and conduct human body research at a super speed, but the human body is not that easy to control after all.

Human body research itself is very related to ethical and moral issues, but with Catherine, without this restriction, human body research can be carried out at an incredible speed.

At this time, the research on the human body itself can no longer be measured by the standards of the 21st century.

Catherine doesn't know exactly how far it can develop.

In the research and development of the "intestinal chip", Jenny implanted a layer of human intestinal cells into a small flexible porous film, and then attached the film to the wall of the chip. Using the impact of a small air pump, the film can become like a real

The "intestinal chip" created in this way is very close to the real human intestine, and its surface can even allow the growth of bacteria.

In the "lung chip" created, Jenny and the researchers implanted human lung cells on the top of the chip, added a layer of thin film in the middle, and added human capillary cells on the bottom. *1*1* They also used an air pump.

, pass the air through the top of the chip, and the "human blood" at the bottom of the chip will start to flow. It will also expand and contract like real human lungs.

With alternating proteins, all research has become extremely simple. This is by no means a difficult problem that can be easily solved in later generations, but relies on Catherine's genes.

Combining microfluidic technology and silicon chip technology greatly accelerates the analysis process of biological systems.

If it weren't for the current chip technology's inadequacies, this research could be even more in-depth.

"Is this an artificial...intestine?"

When Catherine saw the "bump", she really didn't know how to describe something that looked like stool.

In my impression, there is such technology in Catherine's mind, but thanks to Catherine, this kind of technology can be developed so quickly in this world.

"Yes, but there's one thing that's a pity, Kate - it can't really absorb energy, and it can't become a biological battery for the human body. It's just a simple simulation, and it's the same as anything else."

Jenny looked regretful.

In her opinion, this product is a failure.

"Don't worry, if you continue to study, you will definitely be able to make a breakthrough."

Catherine said with a smile.

"Of course, I am very confident about this."

Jenny also smiled.

"And in terms of drug testing, the advantages of 'organ-on-a-chip' are also obvious. This technology can not only be used here: they can simulate real human testing to a very high degree, and the transparent chip can make the observation change."

It is very easy. When researchers need to test a drug, they only need to add the compounds contained in the drug to the chip, and then observe how the intestinal cells or heart and lung cells in the chip react; people can also use 'organ chips'

'Test the absorption speed of drugs or food, or the effect of probiotics on human organs..."

"In my mind, it would be perfect if human cells could be completely replaced by machines. But unfortunately, this seems to be an almost impossible thing. It is difficult for me... to do it..."

Jenny admitted that this matter was not so easy to handle.

"This matter is not urgent. We still have a chance and we still have time."

Catherine comforted the other party.

"Speaking of which, how is the research on hematopoietic stem cells going?"

For this hematopoietic stem cell, Catherine endured blood draws for a while. In fact, it was nothing, just like donating blood for free.

"Well, at least so far, the cells have behaved like Mars. However, it is somewhat different from what I expected. These hematopoietic stem cells do not produce large amounts of replacement proteins. Instead, they work like real hematopoietic stem cells, and they can only survive in a simulated human environment.

conditions, otherwise problems will still occur.”

It seems that this matter is not that simple to solve.

"Hmm... I really don't know what my first clone should look like~"

Catherine's mind was already spinning at this time.

She couldn't suppress the strange thoughts in her head.

"Um... By the way, Kate, the Hive Laboratory needs some new equipment."

Jenny said suddenly.

"New equipment?"

The Honeycomb Laboratory is definitely equipped with the most advanced technology in the world. All together, they are the most advanced products of the 1970s. But just like that, Jenny actually said that new equipment is needed?

why is that?

"I need an MRI machine."

Magnetic resonance (mri), also called magnetic resonance imaging technology, is another major advancement in medical imaging after CT. Since its application in the 1980s, it has developed at an extremely fast rate. Its basic principle is to place the human body in a special

Using radio frequency pulses to excite the human body in a magnetic field

The hydrogen atom nucleus inside causes the hydrogen atom nucleus to resonate and absorb energy. After stopping the radio frequency pulse, the hydrogen atom nucleus emits a radio signal at a specific frequency and releases the absorbed energy, which is collected by the receptor outside the body and processed by an electronic computer to obtain an image.

This is called MRI.

Nuclear magnetic resonance is a physical phenomenon. As an analytical method, it is widely used in physics, chemistry, biology and other fields. It was not used in medical clinical testing until 1973. In order to avoid confusion with radiological imaging in nuclear medicine, it is called nuclear magnetic resonance.

Resonance imaging (mr).

But that was in the original history.

Nowadays, nuclear magnetic resonance technology has not yet been fully applied. Following the development of Catherine, nuclear magnetic resonance technology has also made breakthroughs. With the help of supercomputers, nuclear magnetic resonance technology has also improved a lot.

Hydrogen nuclei are the preferred nuclear species for human body imaging: various human tissues contain a large amount of water and hydrocarbons, so the nuclear magnetic resonance of hydrogen nuclei is highly flexible and has strong signals. This is the reason why people prefer hydrogen nuclei as human body imaging elements.nmr

The signal intensity is related to the density of hydrogen nuclei in the sample. The water content ratio of various tissues in the human body is different, that is, the number of hydrogen nuclei is different.

, then there is a difference in nmr signal intensity. Use this difference as a characteristic quantity to separate various tissues. This is the nuclear magnetic resonance image of hydrogen nuclear density. Between different tissues of the human body, between normal tissues and diseased tissues in the tissue, hydrogen

The difference in the three parameters of nuclear density, relaxation time t1, and t2 is the most important physical basis for MRI to be used in clinical diagnosis.

When a radio frequency pulse signal is applied, the energy state of the hydrogen nucleus changes. After the radio frequency, the hydrogen nucleus returns to the initial energy state, and the electromagnetic waves generated by the resonance are emitted. The small differences in the vibration of the atomic nucleus can be accurately detected, and after further computer processing,

That is, it is possible to obtain a three-dimensional image that reflects the chemical structure of the tissue, from which we can obtain information including the difference in moisture in the tissue and the movement of water molecules. In this way, pathological changes can be recorded.

23% of the weight of the human body is water. Such a high proportion is the basis for magnetic resonance imaging technology to be widely used in medical diagnosis. The water in organs and tissues in the human body is not the same, and the pathological processes of many diseases will lead to changes in the form of water.

, which can be reflected from the magnetic resonance image.

"I will apply MRI technology to the brain. This is the most important thing. Otherwise, the control system cannot handle it. Even if we have a puppet, it will be just a puppet."

"……ha?!"

It’s completely different from what Catherine thought!

"brain?"

"Yes, use MRI scanning to analyze the brain's response when the human body is moving. So I need this technology."

"..."

"Kate?"

"Oh well."

Catherine found that she seemed to be a little behind the times. Sure enough, professional problems must be solved by professionals.

"In the next experiment, I will first make the shape of the experimental object. This is no problem at all. Through electrical signals, we can already make an arm that looks like a human body... As long as there is a stable control system, this

The technology will be very mature."

"Speaking of which...Kate, what kind of new body do you want?"

"What's your new body like?"

Catherine looked at the ceiling and began to think.

"Well, the height is 167 centimeters, and the measurements are 92, 60, 88. Well, the face of an Oriental is just right. The new body is ready. I will go to China to have a look..."

Ah, by the way, why did I come up with this data by accident?

It seems like...it's Tifa's figure?

How about cosplaying Tifa?
