Lin Lan is also pregnant. She couldn't resist Xiao Su, so she had to go over to help take care of the child. The child is quite adorable. Lin Lan used to always think that she wouldn't like children, but now her perspective has changed.

Lin Lan took the child from Professor Su's hands and went to change the diaper, whether it needed changing or not. Lin Lan is now practicing, becoming very familiar with the diaper-changing process.

Professor Su, Yang Ping, and Su Nanchen were chatting together, discussing some academic problems. Su Nanchen's Outstanding Young Talent project is progressing quickly. The new batch of Outstanding Young Talents has almost no problems. Compared to his wife Lin Lan, he is a bit behind. Lin Lan successfully obtained the Outstanding Young Talent award in her first year at Nandu Medical University, becoming a doctoral advisor at the age of 28, making her the youngest doctoral advisor at Nandu Medical University.

This family has Outstanding Young Talents as a baseline. It is estimated that a few Academicians will emerge later. According to the current trend, there is almost no doubt that Yang Ping will become an Academician. With continued efforts, Su Nanchen and Lin Lan also have great hopes in the future. A family with multiple Academicians will definitely become a legendary story in academia.

It's heard that Yang Ping's cross-disciplinary project, K Therapy, has been successful. The project has entered the next phase. Professor Su was quite surprised that such a large project was completed in just over a year, with almost all targets achieved. It truly is incredible.

Recently, Professor Su's project encountered difficulties. After achieving initial results in the research of biological bone cement, there has been no further progress.

Ordinary bone cement forms a hard substance after being injected into the bone. It is commonly referred to as bone cement because the process of transforming from liquid to solid resembles cement, but in fact, its composition has nothing to do with cement.

This type of bone cement is used in many areas, such as vertebral compression fractures in the elderly. Previously, patients had to lie in bed for more than a month before trying to get up slowly; some were bedridden for up to three months. Elderly people should avoid being bedridden, as it easily leads to complications from being bedridden.

After the emergence of bone cement, there was a new method for treating these patients. Using a puncture technique, the bone cement is injected into the vertebral body. During the injection, it remains in a thread-like liquid state. After injection, it quickly solidifies into a hard solid, which can replace the originally injured bone structure to support weight. This way, the pain caused by vertebral fractures disappears, and the patient can get up and walk within a few hours, without the need for long periods of bed rest as before.

However, bone cement is a double-edged sword. While it provides patients with immediate pain relief, it also causes some problems. Its hardness far exceeds the reduced strength of the bone, so in subsequent activities, the adjacent vertebrae collide like eggs hitting a rock, easily leading to compression fractures of the adjacent vertebrae.

To solve this problem, Professor Su is trying to develop a new type of bone cement. After being injected into the vertebral body, it provides mechanical support like ordinary bone cement in the early stage. Later, it can induce new bone growth like some artificial bones. After a period of time, the injected bone cement is replaced by the body's own new bone tissue. Professor Su calls this biodegradable bone cement.

Professor Su initially succeeded. The injected bone cement can provide mechanical support and induce new bone growth. However, its induction effect gradually diminishes, unable to reach the ideal state. In the end, the new bone cannot completely replace the bone cement, with almost half of the bone cement remaining as a foreign object like ordinary bone cement.

Professor Su concluded that this is a material formula problem. However, finding the best formula is easier said than done. It's like developing a new drug, requiring a lot of trial and error to obtain the corresponding effects of various formulas, and ultimately find the best formula. Professor Su knows this process can take a long time, ten or twenty years is a normal span. But as a scholar, who doesn't want to get the most satisfactory results as soon as possible?

When discussing the progress of this project with Yang Ping, Professor Su frowned deeply and couldn't help feeling a bit down. Yang Ping noticed all of this.

"Since it can induce new bone growth, it means the general direction is not wrong. Perhaps the optimal ratio of some components hasn't been found, or maybe some component is missing. In any case, the issue definitely lies with the formula," Yang Ping analyzed.

Su Nanchen nodded in agreement with Yang Ping's opinion. But material formulas require long-term, extensive work to complete trial and error, like the key materials of an aircraft engine. The ratio of various metals in such an alloy requires a lot of trial and error to find the most satisfactory formula, renowned as the hardest nut to crack in the industry.

Trial and error is Yang Ping's specialty. It can be said that trial and error has always been the lowest-cost task for Yang Ping. He can complete this work in the System Space, so it doesn't take much time at all.

In the System Space, not only is there a large amount of time vertically, but horizontally, thousands or even tens of thousands of similar experiments can be conducted almost simultaneously, with the help of computers and robotic arms anyway.

The System Space cannot replace Yang Ping's innovation. He can only complete experiments according to Yang Ping's intentions, but it has time and space advantages. In reality, a short period may equate to days or months inside, which is the time advantage.

As for space advantage, in reality, even if there are dozens of teams conducting experiments simultaneously, each team responsible for testing one formula can only test a few dozen formulas at the same time.
