"Don't talk about business, just about technology and the future." Tencent Science WE Conference slogan has not changed for ten years.

Perhaps it is this pure attitude towards basic science that has made previous conferences a valuable meeting in popularization and prospects for cutting-edge scientific projects. Audiences with different knowledge backgrounds can always find new expectations from this conference.

For example, at the 2022 Tencent Science WE Conference, the cutting-edge breakthrough in China's " Controllable Nuclear Fusion " energy research shared by Chinese Academy of Engineering and Academician of the Chinese Academy of Engineering and plasma physicist Li Jiangang attracted the attention of "NoNoise Reduction".

Academician Li Jiangang introduced at the meeting that the Oriental Superring (EAST) independently developed by my country is the first fully superconducting tokamak nuclear fusion experimental device in the world, and is known as the "artificial sun". Last year, EAST set a world record twice, achieving repeatable ionic operation of 120 million degrees Celsius for 101 seconds and 70 million degrees Celsius for 1056 seconds. What makes

exciting is that fusion can not only generate electricity, but Li Jiangang mentioned that this technology can also reduce the cost of instruments for proton therapy. If it becomes popular, it will undoubtedly be a major benefit for cancer patients.

"Noise Reduction NoNoise" learned that protons were used to treat cancer 20 years ago in the field of medicine, and proton therapy is one of the most ideal tumor radiation therapy technologies internationally recognized. In short, the principle is that the proton beam enters the human body through the "Prague peak effect", and the energy at the tumor suddenly increases. This "precision explosion" treatment method reduces the side effects of radiation therapy on normal tissues and greatly improves the quality of life of cancer patients.

Chen Jiayi, director of the radiotherapy department of Ruijin Hospital, revealed in an interview that clinicians often sighed when discussing difficult cases, "If this patient can be treated with protons, the outcome may be different." However, domestic treatment instruments have long relied on the import of the whole machine, and are expensive.

Academician Li Jiangang revealed a key information at the conference. The proton cancer treatment instrument with a unit price of 5,000 yuan per unit has been developed last year and has begun to be applied to the clinical stage.

It is understood that Lanzhou Institute of Neutral Science used heavy ions to make proton therapy instruments about 10 years ago, "But its whole thing is very large, like our hall, with a diameter of 50 meters. The other is also very expensive, 800 million or 900 million. If you really want to buy it, it may cost 800 million, and even if you mass-produce it in the future, it will cost 500 million. If the common people treat it once, it will cost 300,000 yuan. Even if you treat it three or five times, it will be very expensive. The key is that there are few instruments. If there are fewer, the patient will have to queue for a long time."

Now, superconducting can make the instrument small, and the size can be like an operating table about two meters. The cost has also dropped to about 100 million yuan. "100 million yuan, just one county hospital, can be (bearable), so the people can go to see it, and it can be cured once for 5,000 yuan." Li Jiangang predicted that in about five years, such instruments will be widely popularized and benefit various cancer patients. The basis is that it only takes about three or five years to produce a scientific instrument to serve patients very well.

This means that in the next three to five years, more cancer patients will be able to enjoy proton therapy, and the quality of life of these groups has been significantly improved. Friends who are interested can continue to study the progress and trends in this field in depth.

"Noise Reduction" just wants to say that similar cutting-edge sciences come to the application layer and quietly change the details of the world's operation. It also constitutes a part of Tencent Science WE Conference. Science includes both the romance of starry sky and the sea, the collective destiny of mankind, and the romance of exploring the origin of the universe, as well as the lofty sentiment of practical application and enhancing individual dignity and quality of life. These constitute the "future", and therefore continue to increase everyone's eager expectations for basic science progress, including Ma Huateng, the sponsor of Tencent Science WE Conference.

Ten years ago, Ma Huateng planted this "seed".Over the past ten years, 87 top scientific researchers in the world, including Hawking, Penrose, Pan Jianwei, , Yao Qizhi, have successively delivered speeches on cutting-edge fields such as cosmology, theoretical physics, life sciences, , and information technology. The total number of public attendees online and offline is nearly 100 million. At the Tencent Science WE Conference

2022 Tencent Science WE Conference, Tencent Senior Vice President Guo Kaitian announced on the spot that Tencent is building an open permanent science and technology museum at Qianhai headquarters in Shenzhen. It will work with top scientific research institutions to use artificial intelligence and full-true interconnection technology to create a century-old "technology tree" of human beings that integrates digital and reality.

This "tree" will take basic disciplines as its roots and evolve into branches with the development of disciplines, systematically presenting the development context and breakthrough achievements of a century of science, allowing people to immerse themselves in the experience of human scientific achievements. Tencent will use an open mechanism to invite scientists and scientific and technological workers to create a "technology tree" together and continue to record scientific progress.

Perhaps we ordinary people have continued to look forward to it because of this.
