Lunch was prepared by Nadia at the request of Lin Yilong, and the choice was a variant of the sandwich - a burger - and the side dish was fries.

In front of each person, there are four different kinds of meat sandwich burgers, on which are written four different markings of "fish", "pork", "beef" and "shrimp".

"Is this beef?" asked Sally, who had been anesthetizing a cow all morning as Vera had instructed her, and then watched the operation as Natasha's assistant to the surgeon, and had a little nausea for the beef at lunch.

"You'll know if you eat. Lin Yilong poured himself a glass of Coke Zero and said with a smile.

"It's true. "Sally tasted it carefully, it was the texture and taste of the beef.

"Are you sure?"

"Sure!"

"I'm sure too!" So-yeon raised her hand.

"What about the others?"

"It's beef, no problem. ”

"I'm sure it's beef, and it's very good beef!" Amy said of it, "a bit like the kind of frosted beef I had at Harold before." ”

"Seconded. Katie came to the same conclusion.

"Please eat the next slice. Lin Yilong sent a table next to each family member, so that they were not limited by "herd thinking" and answered their most practical feelings.

The lunch lasted thirty minutes, but even when it was answered, everyone had almost the same answers.

"I'm sorry to tell you. Lin Yilong ate the bacon beef burger in front of him, "You all answered incorrectly." ”

"What do you mean?"

"Because none of the meat on the table is real meat. Lin Yilong replied, "You know artificial meat!"

"Yes!"

"Now there are two different models of artificial meat, one is plant protein simulation, and the other is skeletal muscle stem cell culture. Lin Yilong explained, "This is the product of the latter's technical route, artificial beef made by cloning technology through synthetic cell nutrient solution." ”

"Isn't this still real meat?" Natasha interjected, "but it's not natural." ”

"Can you turn a piece of beef skeletal muscle into beef?" Lin Yilong said with a smile, "We define beef as 'meat taken from a cow'! ”

"It's just not natural, Daddy is cheating. Vera supported her daughter.

"Alright, although in the end, it must be logical that I won, but that's what it means. Lin Yilong said, "Do you taste any difference?"

"Not really. ”

"That's it!" Lin Yilong said, "because the cost of this kind of thing is not particularly low, but if there is a crisis, it is always no problem to deal with it - it is much better to synthesize directly from the chemical materials stored in the biological factory than to raise animals with the same kind of feed." Because the difficulty of cultivation is the same, if it can be made into a gold standard meat steak, it can still be profitable. ”

"But those who can really afford it don't eat artificial, gold-label cutlets, and the rest can't afford it. Katie points out the biggest problem with the commercialization of this technology.

"In other words, there is no commercial prospect until the beef production capacity crisis?"

"At least, we can eat frost snowflake beef every day!" Lin Yilong decided to ignore this substantive problem, "because our test site is sufficient, and we can manage enough food." ”

"What a surprising discovery!" Vera got up, put the last few fries she had left on Lin Yilong's plate, cleaned up her table, and left.

With Vera taking the lead, the others also found Lin Yilong's jokes boring, and also took care of their plates and cutlery and left.

In the end, in the kitchen, only Lin Yilong was left.

"It can't be that simple. Vera, who had taken the lead in escaping, was the first to return, asking.

"Don't you think Vera is the starting point for solving the food problem and then thinking about other issues?" Lin Yilong asked rhetorically, in order to observe the children's reaction, he only took two bites of the burger and was putting his food back in the oven to reheat it.

Because Natasha and Sally may not think of any other way to use it, Katie isn't too familiar with bioengineering. Vera returned to the table with a cup of tea, "That's certainly not the way you think about using this technology." ”

"Definitely not. Lin Yilong replied, "But I was a little disappointed by the daughters' answers." ”

"Give them some time. ”

"Don't give it. Lin Yilong replied, "With the children's associative power, this is a conclusion that should be deduced at the dinner table, since it can't be imagined." ”

"What about your idea, Yilong, is it really a direct commercial use?" Vera asked, "If according to your assumption, there is no essential difference between the cultivation method of skeletal muscle and internal organs, and even because of the composition, it is even more difficult. ”

"Although I know that the first person to figure this out should be Vera. But I didn't expect Vera to be so fast. ”

"My Ph.D. dissertation was about how to build immune pathways to attack cancer cells. "So, even in terminally ill patients, as long as the immune system is fine, we can use genetic sequencing to prescribe the right cure." As for the rejection reaction during organ transplantation, it is covered in the paper. ”

The reason for the "......." turned out to be his own head, Lin Yilong changed the topic stupidly, "Finally, what does Vera think of these fish and meat for lunch?"

"I came to the same conclusion as Natasha, what could be the difference between the skeletal muscle and fat of the corresponding cow or other animal. Vera asked.

"According to the amount of food, if our family slaughters cows, the size of less than 100 cows is not enough for us to eat every day. Lin Yilong replied, "So, use this as a reasonable supplement, in the future, those natural black cattle will be our gene pool, no need to hunt and kill, when you want to eat meat, draw some blood from them, and you can have top-quality snowflake beef after three days of laboratory cultivation." In fact, the most critical problem is that as long as the laboratory process is standardized, it can be turned into automated assembly line production, and there is no need for special personnel to slaughter cattle. In addition....."

"What else is the reason? It can't be the so-called 'humanistic care' for cattle. ”

"Of course not, what I think is that we can pay for 'R&D expenses' for the beef grown in the laboratory, and we don't have to buy beef, and we have free high-priced beef to eat every day. ”

"......" Vera was very speechless, Lin Yilong turned around in such a big circle, just because he was lazy and didn't want to send the cattle to the slaughterhouse by himself, "I have some questions, if it is replaced by a human organ, how long will it take to cultivate it at the earliest?"

"If you don't consider cost control and use the combination of various parts, it will take about 4-5 days to cultivate a human liver, 3-4 days for the pancreas and spleen, 10-12 days for the kidneys, and about 5 days for the heart. Lin Yilong replied, "But I don't think the medical ethics committee will agree to such a bold innovation." ”

"I knew my man would have a way. Vera laughed, "After all, someone pays for your meal, doesn't she?"
