The mother found an answer after she became a scientist when the child died suddenly.
The secret of some children's unexplained death may be hidden in DNA. Some children die for some reason. In the summer of 1997, Maria, the 15-month-old daughter of Laura Gould, had a fever one night. The next morning, the child seemed to be getting better and would dance to the TV. Maria is asleep at noon, and Laura is going to take her to the doctor later. But the child never woke up.

Medical science Why are women more likely to suffer from Alzheimer's disease than men? In previous studies, they have found that the activation of C/EBP β / AEP signaling pathway can promote α-amyloid production and Tau protein accumulation, which is a key factor leading to neurodegenerative diseases. In the new study, they found that follicle-stimulating hormone (follicle-stimulating hormone,FSH) significantly affected these signaling pathways in postmenopausal women. In their blood, the concentration of FSH is about 10 times higher than it was before menopause, while the concentration of this hormone in men is only 2-3 times higher. It has been found that when FSH binds to the FSH receptor on neurons, it can activate the C/EBP β / AEP signal pathway, which leads to Alzheimer's disease. Using female mice with hysterectomy, they found that the pathological characteristics and cognitive impairment of mice were alleviated when anti-FSH antibodies were used to reduce the concentration of FSH in the blood or to inhibit the binding of FSH to its receptors in the hippocampus of the brain. In addition, injecting male mice with FSH also increased their risk of developing Alzheimer's disease.

Health Less than one hour of muscle intensive training a week can help reduce the risk of death. Recently, a study published in British Journal of Sports Medicine found that 30 to 60 minutes of muscle intensive training per week can reduce the risk of death from all causes of death, cardiovascular disease, diabetes and cancer (10% to 20%), but it is not clear whether more than one hour of training per week will further reduce the risk of death.

What is Real?
In a recent podcast hosted by Lex Fridman, the clinical psychologist Jordan Peterson asked: “What is real?” Jordan knocked on the table in front of him and confirmed: “matter is real.” He then continued: “What else? Pain is real, love is real.” As he described human feelings, I thought to myself: “Well, real things are associated with physical systems, and pain or love are just emergent phenomena in the complex human body.” The laws of physics describe all real entities.

Xiaoguan | there are despicable small potatoes in the world. I want to be mean.
one There are about three kinds of people in the world: great people, mediocre people and small potatoes. Greatness is always in the minority, and they can sacrifice themselves. Most people are mediocre, stay in peer-to-peer transactions and get along with others in a balanced state of mind: if you respect me, I will treat each other politely.

A rational Analysis of panic
When we panic, when we think that we have taken all kinds of action, the world does not treat us well, but wastes our wealth and time, and once again gives us the label of stupidity. Why do we often panic and always make one-sided decisions at this time?

The Evolution of morality in different stages of Life
Every parent and elder is the most important part of moral communication, and they have inherited many moral norms in their minds: which behaviors are absolutely inviolable, which are to be seriously warned, and which are relatively minor. When their children are young, they tell them about the moral standards that have been formed in their hearts through daily little things. The moral values of the elders have a direct impact on the moral world of their children, and parents and elders draw noble or humble outlines in the hearts of their children. In a word, our moral concept is passed down from generation to generation, and morality is constantly changing and even evolving in the process of spreading. This is the starting point for children, but things are not so absolute.

The shaping of people's hearts and emotions by "repetition"
When we recall less, our minds are sensitive and tend to consider personal emotions at the expense of others. When we act in vain, we always receive blows and rejections from others, and experience a lot of confusion in our hearts; when we hit enough times, we slowly change our behavior and thinking. If we do not choose to change, our hearts will continue to sink in the tingling, grievance and trouble of the cycle. Therefore, we pursue maturity, stability, morality and bearing, nothing more than to avoid harm, nothing more than to follow the simplest idea of seeking advantages and avoiding disadvantages. We are not as great as we imagine. the so-called nobility is just a mature elder who can easily master the idea of seeking advantages and avoiding disadvantages....

Astronomy There are about 40 million, 000 black holes in the universe. The number of black holes in the universe is one of the urgent questions to be answered in the field of modern astrophysics and cosmology. In a recent study published in the Astrophysical Journal, scientists calculated for the first time that the number of constant-star black holes (with masses ranging from a few to hundreds of solar masses that originated at the end of the life of massive stars). Most black holes in the universe belong to constant-star black holes, and it is estimated that there are about 400 billion black holes in the observable universe.

An alien spaceship just passed by. Solar system scientists are going to catch up with it.
In 2017, astronomers discovered an uninvited guest in the solar system: the interstellar rock Omaomo, which is the first time a celestial body from outside the solar system has been observed to enter the solar system. However, some of the strange properties of Omaomo seem to suggest that it is not formed naturally, and some scientists even boldly speculate that it is an alien ship that intruded into the solar system to gather information near Earth. Now that Aomomo has moved beyond the orbit of Neptune, in order to reveal its true face, some scientists have proposed that we should launch a probe to catch up with Omaomo and take pictures of it.

Can the train for brain death turn back temporarily?
"the station ahead is brain death." When a sudden cardiac arrest occurs in humans, there is no blood supply to the brain and oxygen cannot be transported, which will cause hypoxia in brain cells. Our brains are very sensitive to this, and if we continue to lack oxygen, brain death may occur in about 10 minutes.
