　　This year, "night school", a word with a sense of the times, suddenly became a "good heart" for young people and quickly spread all over the country. In Beijing, Guangzhou, Xi ‘an, Wuxi and other places, the popularity of various interest courses is comparable to that of online shopping. More and more young people go into the classroom to brush their lessons after punching out, ranging from dance vocal music and calligraphy and painting to non-legacy work, health and fitness … They are opening the "nightlife" mode in a different way.

　　Why do young people rush to attend "night school"? At the moment when material life is becoming more and more abundant, people are pursuing the richness and diversity of spiritual life, and the "Youth Night School" with the price close to the people and fashionable and novel courses just conforms to the pursuit of colorful spiritual life by contemporary youth, and it is natural that its popularity will continue unabated.

　　Some people compare the Youth Night School to the adult version of the "Children’s Palace" and the youth version of the "University for the Aged". For young people, it is an "energy supplement station". Some people sign up for study to fulfill their childhood dreams, while others are to improve their skills … "Night school" gives them the opportunity to choose to study and charge according to their interests and needs, and "store energy" for their future. In the process of learning without the pressure of examination, young people unload the pressure and fatigue brought by work and life, immerse themselves in learning a certain knowledge or skill, and enjoy the pleasure of "wasting time on beautiful things".

　　Youth night school is also a "big social classroom". Many young people once lamented their "formatted" life: after finishing work at 5 o’clock, they would pass the time by watching dramas, often lying down and brushing their mobile phones until late at night, which not only made them feel empty mentally, but also affected their health. "Don’t’ house’, come out!" Night school gives young people the opportunity to break out of their homes, reconstruct their cultural life and go to the social classroom. "Youth Night School" also provides a brand-new social scene for young people, making friends with similar interests, broadening their circle of friends, and some even finding life partners.

　　Youth night school is a "dream-chasing place". Going to night school is an independent choice of contemporary young people who actively seek knowledge and are eager to improve. Behind it is the popularization of the concept of lifelong learning, which shows their spirit of being unwilling to be mediocre, uneasy with the status quo and positive. "Youth Night School" gives young people the opportunity to pursue their dreams, so that they can tap their potential with love for life, improve themselves in advance, and reshape themselves in their studies.

　　Young people have no trivial matters, and everything is always related to their feelings. Youth night school has become a new fashion, but if it is not only a temporary craze at this time, we need to seriously think about: how should youth night school serve young people more and better? In this regard, on the one hand, the quality of the course is the key. Only by providing high-quality course content and teachers, can we better meet the learning needs of young people and make evening schools have lasting appeal. On the other hand, it is necessary to "revitalize" more public cultural resources, build a broader learning platform for night schools, and build a learning city where everyone can learn, learn everywhere, and learn from time to time, so that young people can really fall in love with learning and the city where they live. In addition, young people in rural areas and remote areas can also be included in the "night school" education platform through online lectures, so that happy study nightlife can cover more people in need.

　　Youth night school lights up the nightlife of young people, allowing more young people to take the initiative to improve themselves and embrace the new era. In this two-way trip, a little bit of starlight condenses the confidence and strength to move forward towards a better life. (Have fun)

　　BEIJING, Beijing, July 4 (Shangguan Yun) According to media reports, from July 2 to 12, the World Heritage Conference will be held in Poland, and Hoh Xil in Qinghai and Gulangyu in Fujian will sprint the world natural heritage and cultural heritage respectively. Previously, the total number of world heritages in China has reached 50, including natural heritage and cultural landscape, which are either magnificent or profound. So, how many of these 50 amazing world heritages do you know?

　　In 1977, the World Heritage Committee held its first general meeting in Paris, France. On December 12th, 1985, China acceded to the Convention for the Protection of the World Cultural and Natural Heritage. In 1987, China’s Great Wall, Mogao Grottoes, Ming and Qing palaces, Qin Shihuang’s Mausoleum and Terracotta Warriors Pit, and Zhoukoudian Peking Man Site were also included in the World Heritage List.

　　Needless to say, the Mogao Grottoes are also known as the Thousand-Buddha Cave in the above-mentioned list of China’s first batch of World Heritage sites. It is said that it was built in the pre-Qin period, with 735 caves and 45,000 square meters of murals, which makes visitors who have seen the real thing amazed. Shu Lang’s "flying" is a business card of Dunhuang Mogao Grottoes; The grandeur of the Great Wall has also left a strong mark on the world heritage.

　　Ancient cities and villages are also places worth visiting among these 50 world heritages. Like Pingyao Ancient City, it is located in Pingyao County in the middle of Shanxi Province, and was built in the period of Western Zhou Xuanwang (827-782 BC). Pingyao, Shanxi Province is known as one of the "four best preserved ancient cities". The residential buildings in the ancient city have strict layout, clear axis, exquisite wood carving, brick carving and stone carving with strong local flavor and paper-cut window grilles, which are vivid and lifelike.

　　The completion of Dujiangyan has made the Chengdu Plain "flood and drought come from people, I don’t know hunger, there is no famine, and the world is called abundance". This is a description of Dujiangyan in Historical Records, from which we can see the importance of this ancient water conservancy project. At the 24th General Assembly of the United Nations World Heritage Committee in 2000, "Qingcheng Mountain — Dujiangyan is listed in the World Heritage List.

　　Dujiangyan was built in the 3rd century BC. It was a large-scale water conservancy project built by Li Bing, the prefect of Shu County of Qin State, and his sons during the Warring States Period. It is the oldest and only preserved water conservancy project in the world, characterized by water diversion without dams. For more than 2,200 years, it still plays a great role, and is called "the great masterpiece of the civilized world".

　　Shennongjia, a world natural heritage in Hubei, shows us another landscape. In many people’s minds, Shennongjia is famous for the legend of "Shennong teaches people to cultivate crops and taste a hundred herbs", and the Shennong altar is still preserved in the scenic spot. It is reported that there are 3767 species of vascular plants in Shennongjia Heritage Site, more than 600 species of vertebrates have been recorded, and 4365 species of insects have been found. Among them, there are 205 endemic species, 2 endemic genera and 1793 endemic species in China, and the number of the flagship species Shennongjia golden monkey is more than 1300.

　　Why can Shennongjia be selected as a World Heritage Site? The World Heritage Committee gave the answer: Shennongjia, Hubei Province is unique in the world in terms of biodiversity, zonal vegetation types, vertical natural belt spectrum, ecology and biological processes. In particular, its biodiversity makes up for the blank in the world heritage list.

　　Yin Ruins and Fujian Tulou … … It is possible that there will be more and more world heritage sites in China in the future. In fact, whether it is natural landscape or cultural heritage, when they are selected into the World Heritage, it does not mean that they will be protected and utilized once and for all, but on the basis of the original, so that these precious heritages can exist forever with a beautiful attitude.

There are many rules in this world, some of which can support us, but others will hinder our growth, such as "girls should look like girls", "women should get married and have children early" and "girls should not engage in sports that belong to boys" …

Many women have heard similar words when growing up. These voices seem to be everywhere, and the subtle influence and great pressure brought by gender stereotypes limit girls’ lives in all aspects.

But there are some girls who choose to stand up and say "no" bravely-they care more about pursuing their love and exploring the life they want, the life that live high longs for.

"I want to be myself."

Today, we selected 18 female stories that bravely challenged stereotypes and explored the possibility of life.

Let’s feel their power together.

1.

Girls can be strong.-I once climbed a mountain with an altitude of 2338 meters without assistance and only one protective rope.

2.

Girls can have a sense of direction.I have a strong sense of direction and spatial imagination. I like all kinds of maps. I can read paper maps in primary school. I don’t get lost in a strange city, and I don’t turn by car, so I won’t lose my sense of security wherever I go.

3.

Girls can be heroes who save lives.-I lived in a closed village near the Yangtze River. At the age of thirteen, I rescued my drowning classmates in the shallow waters of the Yangtze River. I took off all my clothes before going into the water and finally went home in clean clothes. At that time, I thought it would be good to take off my clothes and put them on, and go home as usual, but I may have misjudged the malice of my peers. I took off my clothes and suffered many attacks.

Today, a long time later, I can finally tell such a thing. I think if I can go back to thirteen years old, I must say to myself: You are so brave, you are so great ~

4.

Girls don’t have to be pleased with themselves.

5.

Girls can talk about sex openly.-Engaged in sex education. I hope to correct some public misconceptions about sex; I hope that China will popularize scientific sex education, so that everyone has the right to enjoy sex freely.

6.

Girls can be the "pillars" of the family.—— In April 2014, less than one year after graduation, the deposit was less than 10,000. The old house (rural house, wooden structure) at home for more than 20 years caught fire because of aging circuits, and everything turned to ashes. There are parents, grandma and I (the only child) at home. It is difficult for parents to save money all year round by farming in the countryside. Grandma is old and sick, and she stays in bed all the year round. I borrowed 100 thousand to build a house for my family. I paid off all my debts this year.

7.

Girls can protect themselves and others without waiting for others to protect them.-When I was in graduate school, the dormitory next door caught fire, and the fire extinguisher was ineffective. After the alarm, I quickly judged the fire and evacuated all the people on this floor and the upper and lower floors. At the same time of evacuation, the students were told to cover their nose and mouth with wet towels, take the stairs downstairs, and finally close (unlock) the fire door to leave, waiting for the fire brigade to go out, and silently watched the time when the fire brigade went out.

8.

Girls can fight against power.-My 25-year-old daughter, I, beat my 51-year-old father who abused his mother.

9.

Girls can give themselves to the world.-Female doctors participated in Doctors Without Borders, and participated in more than a dozen rescue projects in battlefields: Pakistan, Afghanistan, Sierra Leone and Somaliland.

10.

Girls can compete with big men for CPR.

-The female doctors in our emergency department have no pressure _(:3/ ah … So the girls in clinical medical colleges are stronger than those in other hospitals as a whole.

11.

Girls can engage in nuclear weapons.-studying nuclear engineering, yes, nuclear reactor engineering. In four years, PK lost nearly 100 men and won the first place in the whole department; I chose the nuclear reactor experiment for my graduation project. In winter, I wore two down jackets, screwed valves, did electric welding and played with high temperature and high pressure in a laboratory without heating, and finally got the only excellent one at the school level. Now I’m studying PhD in the United States, or I’m still engaged in nuclear studies. The only girl in the group, the tutor doesn’t like my sister to do experiments, so I’ll toss and change my tutor. I hope the toss will not end badly, and I pray for blessings.

12.

Girls can be very courageous.-After leaving the scene of the explosion, fix the position of each corpse at the scene.

13.

Girls can be fearless of challenges for love.—— English major at Grade 13 University of Traditional Chinese Medicine, female. My senior year wants to follow an old Chinese doctor in massage. The other party refused, saying, What are you doing for being so thin and short? Go and get acupuncture. In front of the patients and other brothers, I only took off my vest in the winter. On the ground, with two thumbs, I made ten hungry tigers pouncing on food in a row (like push-ups, but not straight up and down, which is more difficult), and then I became the teacher’s first female apprentice. In the end, the object of study was not this master, and the later master was also a female and a child massage expert. Well, actually, she taught me how to eat like a hungry tiger. She is the only one who can get full marks in the tuina testing instrument in our school, including men and women. Massage major, tall and male, is indeed an advantage. I am 160, and my master is 155. And the performance created by our department is 10% of that of a top three hospital.

14.

Girls can be good at science.-Graduated from the Physics Department, one of the departments with the most unbalanced male-female ratio in Tsinghua University. When we first entered school, we girls often fell into doubt whether we could study as well and do research as boys. Later, when I graduated, a girl went to Princeton to continue her Ph.D. in astrophysics, just because she loved watching the stars in the sky when she was a child. A girl went to Yale to study for a doctorate in geometry, because doughnuts and coffee cups are a topological point. My favorite girls, who dare to love and fight, care whether it is considered the domain of boys dominate.

15.

Girls can not give up their development for marriage and children.-My mother, who got a college diploma when she got married, got her doctorate at the age of 49.

16.

Girls can "go around the world with swords and see the prosperity of the world".—— In the third year of work, the whole person was very consumed and didn’t like this job. Since childhood, he has always followed the so-called correct life track. On my 27th birthday, I resigned and decided to travel: list the places I want to go, make long-term and short-term plans, make strategies, buy equipment, and hit the road! In the past three years, I have visited all the provinces and more than 70 countries in China, seen a lot of scenery and all kinds of life, and the whole person has taken on a new look, with confidence and courage to face life calmly.

17.

Girls can be the best role models for girls.-I want to talk about my mother. In the 1970s, when material conditions were scarce, my mother formed a thinking of equality between men and women from an early age. She believes that the first essence of women is independence, spiritual independence and material independence, and they should have their own independent ideological system. My mother has been living a very lively life, making many friends, mostly male friends. In the face of unhappy marriage, I made a decisive decision, and there was no room to leave home clean. The only requirement was that I must follow her. In that 1990s, how difficult was it for a girl to leave her marriage and leave home with her children? After the divorce, she stayed at her grandmother’s house. On the one hand, she worked in a public institution, on the other hand, she ran her own small business.

When I graduated from primary school, my mother had bought a suite and a car independently. When I graduated from middle school, she sent me to a private middle school by herself. When I graduated from high school, my mother bought two suites and changed three cars. By the time I graduated from college, she had prepared all the money for my study abroad.

However, these material things are not the most important. The most important thing is that she is my best friend. I claim to be an independent and rebellious new woman, but my mother and I are very close. Our communication goes deep into any field, and we are not afraid to hide, criticize or understand narrowly, but empathize with each other, just like bosom friends.

Now that I am in a foreign country, I have to call her for 20 minutes every day, and I have to hug her every time I meet her. This relationship between mother and daughter is envied by everyone around me.

My mother taught me to love and be independent. She doesn’t like housework, but she is very proficient. She cooks good Sichuan food and washes all my clothes. She loves life and everything, so she is unwilling to give up, willing and willing in the process of balancing the relationship between family and career.

18.

Girls can be everything they want to be.

The author said:

I can often feel all kinds of negative comments about girls in society in my life. If you are beautiful, you may suffer from gossip, and if you are not beautiful, you may be bullied; "Strong women" will be said to be "unmarried", and other girls will be said to be "money worshippers"; Not losing weight is called "not self-discipline", and losing weight is criticized as "body anxiety" …

Today’s article is to convey some strength to girls. This is what girls really look like: we have the courage and ability to do what we want to do and become what we want to be, without being evaluated by others and society.

Regardless of gender and circumstances, we can fight according to our own will and strive for live high’s greatest potential. I always think that people are the proudest and dignified when they are struggling.

I hope that everyone who has expectations for what kind of person you "become" can believe that you are destined to shine your own light, and nothing can stop you-sometimes just because you have gained such courage, you are one step closer to what you want to be.

As the saying goes, life lies in exercise, which is true at all. Moderate exercise can improve cardiopulmonary function, promote systemic blood circulation and relieve nervous mood. However, there must be a degree in everything, and the same is true for sports. You need to choose the right sports according to your own situation, and you can’t blindly pursue quantity and duration. If the amount of exercise is insufficient, the body function will slowly deteriorate; Excessive exercise will cause persistent muscle pain, irritability and loss of appetite, and at the same time, it will also reduce immunity and increase the damage to bones and joints.

1. Exercise intensity

Exercise intensity, as its name implies, is the strength spent in exercise, which is determined by the type and purpose of exercise. There are different ways to measure the intensity of exercise, such as jogging or brisk walking. The intensity is measured by the target bull’s-eye rate and based on the maximum heart rate, which is equal to 220 minus age. The bull’s-eye rate of moderate and high-intensity aerobic exercise ranges from 60% to 80% of the maximum heart rate, and strength training needs to measure the exercise intensity by weight and repetition times.

2. Motion frequency

Exercise frequency refers to the interval time of exercise, and the optimal frequency is determined by the type and purpose of exercise. If the purpose of exercise is to lose weight, at least 300 minutes of moderate and high-intensity aerobic exercise a week can reduce weight and body fat; If the purpose of exercise is to maintain good health, you need to have 150 minutes of aerobic exercise a week, and then match it with 2~3 days of strength training.

3. Exercise time

Exercise time refers to the duration of exercise, which is determined by the type of exercise, the purpose of fitness and the level of exercise. At the beginning, you can do aerobic exercise first, and the exercise time is about 15~20 minutes, and the exercise intensity is well controlled; If you want to enhance flexibility through exercise, make sure that each muscle group stretches for about 15 seconds and repeat it three times; If you want to enhance your cardiopulmonary endurance, the duration of high-intensity exercise should not be less than 20 minutes.

4. Type of exercise

There are many types of sports, such as aerobic training, flexibility and resistance training, etc. The specific types of sports are divided into cycling swimming, weightlifting and running, squat and so on. You need to choose the right type of exercise according to your own sports purpose.

1. Moderate intensity exercise

Moderate intensity exercise is equivalent to brisk walking for half an hour to an hour every day. Such activities include walking, shopping, housework and gardening. You can walk more in your daily life for at least half an hour every day.

2, high-intensity aerobic exercise

Common high-intensity aerobic exercises include climbing mountains, swimming and jogging, climbing stairs and aerobics, etc. Exercise at least 3~5 times a week for no less than 20 minutes each time to ensure that the exercise heart rate needs to reach the target heart rate.

3, high-intensity competitive sports and leisure sports

Such sports include basketball, football or tennis, as well as dancing, skating and skiing. Such sports can not only improve heart and lung function, but also cultivate sentiment. Obese or overweight people can choose swimming, which can reduce the joint load.

4, muscle fitness exercise

This kind of sports have their own weight-bearing resistance training, as well as resistance training by equipment, such as dumbbell weight-bearing and elastic belt exercises, which are done at least 2~3 times a week.

5. Flexible exercise

Flexibility exercise includes practicing yoga, dynamic stretching or static stretching, which can be arranged after aerobic exercise or resistance training for 15~30 seconds each time.

Tips

Adults should exercise at least 30-60 minutes every day, and at least 150-300 minutes of moderate-intensity exercise every week. Try to arrange the winter exercise time at noon or afternoon, and the morning exercise time should not be too early, at least after the sun comes out.

The first "Progress Cup" Sun Yat-sen Soong Ching Ling Reading Marathon was launched in Xujiahui Academy. Photo courtesy of the contest organizer

Xu Jing, April 17 (Xinhua) The year 2023 marks the 130th anniversary of the birth of Soong Ching Ling, one of the founders of People’s Republic of China (PRC) and honorary president of the country. The launching ceremony of the first "Progress Cup" Sun Yat-sen Soong Ching Ling Reading Marathon (hereinafter referred to as "Yuema") and the launching ceremony of the question bank were held in Shanghai on the 17th.

The contest was hosted by the Shanghai Sun Yat-sen Soong Ching Ling Cultural Relics Management Committee and the Shanghai Committee of the Communist Youth League, and co-hosted by the Shanghai Soong Ching Ling Former Residence Memorial Hall and Xuhui District Culture and Tourism Bureau.

In this competition, a series of related books, such as Soong Ching Ling, Sun Yat-sen and so on, were read by combining offline and offline, so as to attract a wide audience, including teenagers, to read the grand and magnificent life stories of two great men in the century and approach their three-dimensional and vivid spiritual world.

Soong Ching Ling is the daughter of Shanghai. Her "lovely home" is located in Xuhui, Shanghai, and most of the women’s and children’s cultural and educational undertakings she initiated in her life germinated, took root, flourished and expanded in Xuhui. The launching ceremony of this competition was held in Xujiahui Academy, one of Shanghai’s cultural landmarks. By setting up "Soong Ching Ling’s special bookcase" in this all-media era compound library and entering the hospital to scan the code, the reading was switched online and offline, showing the power of reading to the society and calling on the whole people to read.

On the same day, 150 contestants were divided into student group and adult group. They read the book Soong Ching Ling together in three divisions of Xujiahui Academy, and completed the online question bank and made a comparison within the specified time. After the launching ceremony, various organizations and individuals will continue this "Yue Ma" lasting for 100 days, calling on the whole people to intensively read famous works, enjoy reading, pool their wisdom and enrich their spiritual world.

Ni Yifei, director of the Cultural Management Committee of Sun Yat-sen Soong Ching Ling in Shanghai, said that in recent years, the Cultural Management Committee of Sun Yat-sen Soong Ching Ling in Shanghai has continued to promote the construction of a "great mission" platform with the theme of carrying forward the great spirit of Sun Yat-sen Soong Ching Ling, with the series of activities of "five tours" (tour exhibition, lecture, broadcast, competition and tour) as the starting point to provide quality public cultural services to the public. The first "Progress Cup" Sun Yat-sen Soong Ching Ling Reading Marathon is a touring brand planned and launched by the Cultural Management Committee of Sun Yat-sen Soong Ching Ling in Shanghai this year.

Wu Bin, deputy secretary of the Shanghai Communist Youth League Committee, said that the Shanghai Communist Youth League Committee will widely mobilize the youth of the city to actively participate. I believe that through this competition, the contestants will learn something and learn something. With the joint efforts of many parties, this competition will definitely become a high-quality platform for "innovating the use of red resources and boosting the growth of young people". (End)

In mid-2022, a startup company named Retro Biosciences came into public view, and it announced that it had obtained $180 million for a bold task: increasing the average life expectancy of human beings by 10 years. Just a short year ago, the company was headquartered in a warehouse near San Francisco. There were many containers on the concrete floor, where scientists worked and did experiments.

Retro said that as part of the "radical task", it would "stimulate the speed" and "tighten the feedback loop" in order to stop aging or even reverse it. But it is vague about the source of its funds. According to reports, it was still a "mysterious" startup, and its investors were anonymous.

Now MIT Science and Technology Review can reveal that all the investment was provided by Sam Altman, a 37-year-old senior entrepreneur and CEO of OpenAI.

Altman spent almost all his time on OpenAI, an artificial intelligence company, whose chat bots and electronic art programs have always been unique in the field of science and technology because of their comparable human capabilities.

But altman’s money is another matter. He said that he had emptied his bank account to fund two other very different but equally ambitious goals: pursuing unlimited energy and prolonging life.

He said in 2021 that one of the projects is Helion Energy, a nuclear fusion power generation startup, and he has invested more than 375 million US dollars in the company. The other is Retro, who invested a total of $180 million in the same year.

"This is a lot of money. I basically invested all my current assets in these two companies, "altman said.

Altman’s investment in Retro has never been disclosed before. This is one of the largest personal investments ever made by a startup company seeking to increase human life span.

Altman has always been a well-known figure in Silicon Valley. He used to run Y Combinator, a business incubator in San Francisco, but with the release of ChatGPT by OpenAI and its popularity all over the world, his name has been known all over the world.

It is reported that the breakthrough based on artificial intelligence technology has turned this seven-year-old company into a "member of the technology giant club". Microsoft promised to invest $10 billion in it, and altman, who has 1.5 million Twitter followers, is consolidating his status as a technology tycoon, and his invention will definitely change the society profoundly.

Altman is not on Forbes’ list of billionaires, but he is still very rich. His extensive investments include early shares in companies such as Stripe and Airbnb.

He said: "In the biggest bull market in history, I have always been an investor in technology stocks at an early stage."

Hard core technology

Now, in his words, he has invested his capital in a level that is "orders of magnitude far beyond the Y Combinator era". He has been betting these funds on several technical fields that he thinks will have the greatest positive impact on mankind: artificial intelligence, energy and anti-aging biotechnology.

Helion, headquartered in Everett, Washington, is eager to conquer atoms to create an "infinite clean energy". Joe Betts-LaCroix, CEO and co-founder of Retro, said that the company’s goal is to "prolong human life by discovering how to rejuvenate our bodies".

All these companies, including OpenAI, are what altman called "hard-core" start-ups-companies that need a lot of investment to make scientific progress and master difficult technologies. This is a shift for altman, from supporting fast-growing applications and companies in the era of Web 2.0 prosperity to supporting scientists engaged in long-term research.

Hard science companies need higher capital costs, but altman believes that their bigger goals are more likely to attract talented engineers. He recently quoted Daniel Burnham, a Victorian architect, on Twitter: "Don’t make small plans, they don’t have the magic to stimulate the blood flow."

Although nuclear fusion and life extension may be the most incredible projects (some researchers even think it’s daydreaming), few people believed that artificial intelligence would pass the medical school exam in 2023, just like ChatGPT, a chat robot of OpenAI, did this year.

Altman said that in fact, hard-core startups may have a better chance of success than simple companies. This is because there may be a thousand start-ups developing photo sharing applications, but only a few companies can build experimental nuclear fusion reactors.

enlarge the scale

Altman said that the areas he has been betting on are those where he can see some potential trends, so that technologies that seem impossible today are expected to spread quickly. This is what happened to OpenAI, which was established in 2015.

The company focuses on a machine learning technology called transformer and has steadily expanded its scale. In the process of creating its products, it only spent more than $1 billion on purchasing computing power.

The resulting model (program) can create pictures and complex text paragraphs in a few seconds, even close to human works. "We have an algorithm that we can learn, and as it performs more operations, it seems that it can be further extended," altman said.

As for the realization of controlled nuclear fusion, the trend that altman sees is bigger and stronger magnets. In order to fix the 100 million-degree thermal plasma vortex in the reactor core, we need very powerful magnets. Altman said that he initially invested about $10 million in Helion, but later increased the stakes because he was "very confident".

Although the problem of nuclear fusion has not been solved (reactors still use more energy than they produce), he has been urging Helion to list how to build several reactors every day-if nuclear fusion wants to replace coal and natural gas as the main power source, increasing production capacity is a necessary part.

"That’s what I’ve learned from my career. Scale it up and see what happens, "altman said.

Young blood

About eight years ago, altman became interested in the so-called "young blood" research. In these studies, scientists stitched young mice and old mice together so that they shared a blood system. Surprisingly, these old mice seem to have partially recovered their vitality.

This is a terrible experiment, but to some extent, it is very simple. Altman, then the head of Y Combinator incubator, asked his staff to investigate what progress anti-aging scientists were making.

He said: "It feels like this is a result I didn’t expect, and that is another result I didn’t expect. This means that something is happening quietly … Maybe there is a secret hidden here, and it is easier to find than we thought. "

In 2018, Y Combinator opened a special course for biotech companies, inviting companies with "radical anti-aging plans" to apply, but soon after, altman left Y Combinator to concentrate on his increasingly busy work in OpenAI.

By 2020, some researchers in California showed that they could achieve the effect similar to obtaining "young blood" by replacing the plasma of old mice with saline and albumin. This shows that the real problem lies in the "aging blood". Just by diluting it (and the toxins in it), we may be one step closer to drugs that resist or even cure aging.

Bates Lacroiva recalled, "Sam called me and said,’ My God, have you seen this plasma intervention paper?’ That’s not what I said, but the general idea is similar. Bates Lacroiva was a part-time biotechnology partner of Y Combinator and now leads a gathering of longevity lovers.

Bates Lacroix agrees that it’s cool and some companies should pursue it. "How about I fund you to do it?" Altman said.

But Bates Lacroix was already studying a different idea. He just finished an early joint venture project, a company called Vium. The company tried to "digitize" the rat population and added cameras and artificial intelligence to monitor the experiment. Vium has raised more than 50 million dollars, but it has not been successful. That year, it was merged into another biotechnology company, which bought its assets for $2.6 million.

Bates Lacroiva’s new plan is to set up a company to pursue cell reprogramming-another hot area involving the technology of making cells younger through genetic engineering. He has collaborated with Chinese scholar Ding Sheng Ding who has developed a new method of reprogramming cells. Bates-Lacroiva also believes that the process that cells use to process toxins (called autophagy) may be a direction worth exploring.

Altman’s answer is: "Why don’t you do all these things?"

"I will. I will set up a multi-project company around the biology of aging, which is a big project, "Bates Lacroiva recalled." Then he said,’ Great, let’s do it.’ "

The new company needs a lot of money-enough to keep it going for at least seven or eight years while conducting research, encountering setbacks and overcoming them. And it needs to finish the work quickly. The expenses of many biotech startups are decided by the board of directors, but in Retro, Bates-Lacroiva has all the decision-making power. "There is no bureaucracy here," he said. "I am a bureaucracy."

For example, Bates Lacroix did not wait for scarce laboratory space, but filled a warehouse with 40 prefabricated containers and used them as laboratories. This means that he can quickly carry out the first experiment, including repeating some plasma work on mice. Bates Lacroiva presented some preliminary results at a conference in 2022, saying that mice undergoing plasma exchange seemed to become stronger.

Mysterious start-up company

Retro employees submit experimental memos every week to record which work is progressing smoothly and which work is frustrated. Bates Lacroix said that he usually calls altman on weekends to tell him the highlights, and altman sometimes makes suggestions.

However, up to now, things related to this company in altman have been kept secret. This is a decision made by Bates Lacroiva, who wants Retro to open its own path. Altman agreed, because he tried to be "very careful not to hide the brilliance of the CEOs I worked with."

When Bates Lacroiva officially disclosed the company information in mid-2022, in a series of tweets, he still didn’t disclose altman’s name, but said that he was "lucky to get the initial capital of 180 million dollars", which was enough to "safely" support the company to run until 2030, when it planned to realize "the first proof of concept to extend life".

People familiar with the company’s thinking say it’s also because altman’s name may be a distraction. Of course, he is famous, but this reason may be wrong. Although altman’s position in the entrepreneurial world is unparalleled, his reputation is almost nonexistent in the biological laboratory and pharmaceutical industry, and a person’s scientific record is the most important in this circle.

"I’ve never heard of the name Sam altman," said Irina Conboy, a researcher at the University of California, Berkeley, although her work on plasma has amazed Sam. But she is really more familiar with Bates Lacroiva and his research on longevity.

"100 million is just a number, not a breakthrough," Comboy said.

Public discontent

Every technology also has risks. As far as artificial intelligence is concerned, it is chat bots that may spread lies and false information. As for reversing the age, if it is really effective, one of the risks often mentioned is public dissatisfaction, especially if it will be offered to the rich like altman first.

The basis of this idea is that if altman’s financial support is magnified conspicuously, Retro may become a victim and be classified as a vanity project misled by billionaires in pursuit of immortality.

We have reason to be so worried. In 2016, Peter Thiel, one of altman’s mentors, was ridiculed by the media as a "vampire looking for young victims" after he expressed interest in receiving anti-aging blood transfusion treatment. A year later, HBO’s spoof program "Silicon Valley" released an episode called "Blood Donation Boy". In the film, the CEO of a fictional technology company is in a meeting, and his vein is connected with that of a handsome young man called "blood transfusion assistant".

"We really don’t want to see those old billionaires pay for plasma donors," Bates Lacroiva said in the summer of 2022. Instead, he said, the company hopes to find more "credible" interventions, such as drugs that mimic the effect of blood replacement, for millions of people to use.

"We don’t want to treat billionaires with prejudice. I’m just saying that we don’t want to see treatments that are super expensive, awkward and difficult to implement. "

Altman said that his personal anti-aging methods include "trying to eat healthily, exercise and get enough sleep" and taking metformin. Metformin is a diabetes drug, but it is very popular in Silicon Valley because it may make people without diabetes healthier. "I hope I can use Retro therapy one day!" Altman said.

OpenAI in the field of anti-aging

Anti-aging research seems to be a promising investment field. One reason is that it has not received much funds in the past, at least relative to the scale of the research project. According to the data of the Center for Medicare and Medicaid Services in the United States-about $4.3 trillion, accounting for nearly one-fifth of the GDP of the United States-it is used for medical care, most of which is used to treat the elderly. Longevity researchers generally believe that if a drug can delay aging, it may help delay a series of serious diseases, including cancer and heart disease.

Bates Lacroiva said that in order to have the widest impact, he is looking for interventions that can scale up and affect "millions or billions" of people.

However, when Retro lifted the veil, the research on the problem of old age was becoming very popular. The Saudi government said that it will provide 1 billion dollars for related research every year, and an organization called Altos Laboratory has been established, claiming that it has 3 billion dollars. Famous investors are also involved, such as Yuri Milner, and even Jeff Bezos is rumored.

Compared with these investments, altman’s bet looks relatively small, even making Retro look insignificant. One of its projects is to test the rejuvenation technology on T cells, which are part of the immune system and play an important role in fighting infection and avoiding cancer.

These cells are particularly useful because they can be removed, rejuvenated in the laboratory and sent back to the patient. But other startups have similar goals, including Altos and NewLimit, a biotechnology company founded by cryptocurrency billionaire Brian Armstrong in 2022.

The competition for researchers is particularly fierce. Altos persuaded 24 university professors to leave their jobs and offered millions of dollars in salary and other benefits, which absorbed almost half of the top scientists in the field of reprogramming.

But Bates Lacroix also managed to attract some top talents. In 2022, he flew to Switzerland to visit Alejandro Ocampo, a researcher at Lausanne University. In 2016, Ocampo was the first scholar to study the rejuvenation of mice, and his research helped trigger the current craze for longevity investment.

"I’m glad to see Joe coming to see me in person," Ocampo said. He was so grateful for the attention he received that he later agreed to become a paid consultant for the company.

He also said that Bates Lacroiva is willing to accept his view that the age reversal of human beings will not happen in the short term. Some of Ocampo’s recent experiments explored why the reprogramming method he studied would kill some mice instead of making them live longer.

Ocampo said: "Some optimists think that we will achieve eternal life in 10 years, while some pessimists say that we will never prolong human life. As a realist, my personal opinion is that many people are choosing simple and fast experiments, but if we do the same, I don’t think we will go very far. Because this will not be an easy road. "

Ocampo said that Bates Lacroix convinced him that Retro was willing to explore these basic problems with its own funds. "They want to promote the development of science, not just pursue short-term goals," he said. "Other companies want to find an application scenario immediately, but they are willing to spend time exploring basic science."

Bates Lacroiva did not discuss Retro’s funding sources with Ocampo. Ocampo said that he didn’t know that altman was funding the startup until he was interviewed by MIT Science and Technology Review.

In an interview, altman didn’t worry about the competition from other companies. He believes that most biotechnology companies are accustomed to slow action and are usually "not good at management". He believes that the research on longevity needs an "OpenAI-style effort".

Altman said: "Retro’s main task is to become a truly excellent biological start-up company, because this is a rare thing. It combines great science with the resources of big companies in the spirit of a startup company. This is our current project. "
