Hot Review | Nankai professor's resume is trending, netizens: It's so funny

"Hotspot Review | Major Technology Events of the Week" is a new column with pictures and texts launched by Academic Headlines, which aims to help readers quickly understand the hot technology news of the past week. Due to the limited space (and knowledge), everyone is welcome to add more~

Hi, my lovely “academic bacteria”, I am your lovely Academic King.

Last week was another "last week" that has passed.

Last week, the topic "Nankai Professor Hu Jinniu's resume is so funny" once ranked second on Weibo's hot search list. After reading it, I have to say that every word of Professor Hu's jokes really touched my heart.

As the saying goes, you never stop learning. Recently, a 52-year-old freshman at a vocational and technical college in Wuhan, Hubei, was on the hot search list because his age was "abnormal" and the teachers took turns to confirm his admission notice. However, some people believe that middle-aged and elderly people going to college not only wastes educational resources, but also squeezes out the admission opportunities of young people. What do you think?

In addition, Science published an article stating that if the signature of a paper is changed to a Nobel Prize winner, the acceptance rate will soar from 9% to 59%, which is incredible!

But... In addition to these, what other hot news were there last week? Let's take a quick look at them together:

Nankai professor's resume is trending on the Internet, netizens: It's so funny

Self-deprecation is a high-level humor, and also a kind of relaxation that makes light of a heavy task. After being used to seeing neatly formatted resumes, it is quite refreshing to suddenly see university professors making fun of themselves on their official websites. Here’s what happened. On September 17, some netizens found that the topic “Nankai Professor Hu Jinniu’s resume is so funny” topped the Weibo hot search list.

After a careful look, you will find that Professor Hu Jinniu's research may not be understood by everyone, but his jokes are written into the hearts of netizens. He did a lot of postdoctoral and visiting scholars, he said it was because he couldn't find a job; he entered a certain society because of the support of a big boss.

He made thoughtful notes on the research directions, including which ones are the most popular and which ones are "easy to fool".

The sentence “If you don’t believe it, please google it” breaks the stereotype of the big guys being “aloof”.

emmmmm...Just look at the text in the red box in the picture below.

A new weight loss theory! “Eating less at night” is not reasonable? Except for these people

I don’t know when the weight loss advice of “eat less at night” began to be adopted and practiced by more and more elders and friends around us, and they strongly recommended it to us, “eat appropriate breakfast and lunch, and eat less at dinner”. The common explanation is that consuming most of the daily calories in the morning will be more efficient and can help lose weight better. Some extreme weight loss people even choose to only eat some green leafy vegetables at night, or not eat at all.

However, is the advice of “eating less at night” really scientific and reasonable?

Recently, a study published in the Cell journal showed that people who eat more at night do not necessarily gain weight. No matter which meal we eat the most in the morning, noon or evening, it will not affect the way the body metabolizes calories. This conclusion is very different from people's previous cognition.

The study also showed that although eating more at night has been shown not to affect the way the body metabolizes calories, people who eat more in the morning are more likely to lose weight because they are more resistant to hunger during the day and have relatively less hunger.

The Ministry of Science and Technology and 22 other departments issued the "Rules for Investigation and Handling of Dishonest Scientific Research Behaviors", adding 7 new types of dishonest scientific research behaviors

Recently, the official website of the Ministry of Science and Technology announced the "Notice of the Ministry of Science and Technology and 22 other departments on the issuance of the "Rules for Investigation and Handling of Dishonest Behavior in Scientific Research" (hereinafter referred to as the "Rules")", which further standardized the investigation procedures for dishonest behavior in scientific research and unified the handling standards.

In recent years, scientific research misconduct has become more hidden and complex. In response to new forms of manifestation, the "Rules" have added 7 types of scientific research misconduct, including buying and selling experimental research data, signing without substantial academic contributions, and duplicate publication. It also stipulates the investigation and punishment of third-party institutions engaged in paper buying, selling, ghostwriting, and submitting papers on behalf of others. It details the behaviors that violate scientific and technological ethics norms, and emphasizes that obtaining scientific and technological ethics review and approval by fraudulent means, or forging or tampering with scientific and technological ethics review and approval documents are all scientific research misconduct.

The "Rules" state that any of the following scientific research dishonesty situations should be dealt with more severely:

1. Forging, tampering, concealing or destroying evidence;

2. Preventing others from providing evidence, or interfering with or hindering investigation and verification;

3. Attacking or retaliating against whistleblowers, witnesses, or investigators;

4. There is transfer or exchange of interests;

5. Organized scientific research dishonesty;

6. Those who have committed multiple acts of scientific research dishonesty or have committed multiple acts of scientific research dishonesty at the same time;

7. Refusing to admit mistakes despite irrefutable evidence and clear facts.

Scientists discover a new electrical signal that maintains circadian rhythms

Circadian rhythms are coordinated and controlled by the brain's master biological clock, the core of which is the negative feedback between clock genes and their proteins that produces a molecular rhythm with a cycle of 24 hours. For a long time, it was generally believed in the field that the master biological clock itself was sufficient to maintain the circadian rhythm.

Recently, the new discovery of the team of researcher Donggen Luo from the School of Life Sciences, McGovern Institute for Brain Research, Center for Quantitative Biology, and Joint Center for Life Sciences at Peking University has broken through this traditional theory. For the first time, they developed a method to record the fine electrical activity of all fruit fly clock neurons, and further developed the four-electrode patch clamp recording technique of fruit fly brain clock neurons. They observed that clock neurons produced synchronized rhythmic action potential firing throughout the brain, and found that this synchronized firing was completely dependent on synaptic input from outside the main biological clock. This work reveals that the main biological clock of the brain is not sufficient to maintain circadian rhythms by itself, but rather determines the circadian rhythmic electrical activity output by integrating the endogenous brain oscillation input of xCEOs and the membrane potential changes regulated by its own molecular clock. The study suggests that endogenous brain oscillation signals to maintain circadian rhythms may be a core mechanism of the biological clock that is conserved in both insects and mammals.

Scientists find new evidence that cloud-to-cloud collisions lead to the formation of massive stars

The formation of massive stars is one of the hot and difficult issues in current astrophysical research. The two main existing models of massive star formation (competitive accretion and single-core collapse) both have certain shortcomings.

If the time scale for the formation of a massive, high-density mass (core) is comparable to the time scale for the free fall of a low-mass star, the low-mass star will form first, and its feedback will hinder the formation of a massive star. Therefore, the time for the formation of a massive, high-density mass (core) in the single-core collapse model must be very short. Rapid external compression provides a mechanism for the rapid formation of a massive, high-density mass (core).

Molecular clouds composed of a large amount of molecular gas are widely distributed in galaxies, and the "cloud-to-cloud collision" between them is a typical example of rapid external compression. Recently, researchers from the Xinjiang Astronomical Observatory of the Chinese Academy of Sciences used multi-band continuous spectrum data and 12CO and 13CO spectral line data to explore the molecular cloud complex 323.18+0.15 and found strong evidence that cloud-to-cloud collisions lead to the formation of massive stars.

The study found that G323.18+0.15 contains three components with different velocities, G323.18a, G323.18b, and G323.18c. G323.18b presents a perfect U-shaped structure, which is usually left when a smaller molecular cloud collides with a larger molecular cloud. G323.18a complements the U-shaped structure G323.18b well in morphology, indicating that G323.18a and G323.18b collided, and the position-velocity clearly shows the dense component (Bridge structure) formed after their collision and mixing. In addition, the analysis of the gravitational equilibrium state of the molecular cloud and the distribution of young stars also proves that a cloud-cloud collision occurred in the molecular cloud complex G323.18+0.15.

Science: The acceptance rate of papers increased by 50% after the authors changed their names to Nobel Prize winners

The process of having a paper accepted is often full of twists and turns, and can even be very painful. This is an experience that many researchers have had.

(Source: Pixabay)

However, recently, an article published in the Science column "Insider" pointed out that there is indeed a "routine" to increase the acceptance rate: having a celebrity in the scientific community sign it is more conducive to the publication of a paper. If the only author of a paper is an unknown person, only 9.9% of the reviewers are willing to accept it; if the same paper is signed by a Nobel Prize winner, the acceptance rate will soar to 59%. Unfortunately, the strange phenomenon of looking at the "origin" of a paper is very common in the scientific community. Since editors and reviewers are not necessarily colleagues in a small circle in a certain research field, they may not be able to make accurate judgments on the experimental process and experimental data in a paper, so they have a routine operation: reviewers usually use various methods to "find out" the resume of the author of the paper. The more famous the author is, the more papers he has published, and the higher the citation record, the more reliable the content of his article, and there will be a clear bias towards such authors during the review process; and those researchers who cannot find any background information on the Internet are very suspicious.

At the age of 52, he was repeatedly confirmed to go to college. Whose educational resources did he "waste"?

Recently, during the freshman orientation at a vocational and technical college in Wuhan, Hubei, a 52-year-old freshman became a hot topic because his age was "abnormal" and teachers took turns to confirm his admission notice, sparking controversy about middle-aged and elderly people going to college.

Some people believe that learning throughout life is inspiring and worth learning; others believe that middle-aged and elderly people going to college not only wastes educational resources, but also squeezes out the admission opportunities for young people.

However, as early as April 3, 2001, the Ministry of Education officially announced a new measure to reform the college entrance examination system, namely, the college entrance examination will remove the restrictions of "unmarried and under 25 years old" from 2001. This measure is of far-reaching significance and has opened the door to university for thousands of older students.

Some people feel uncomfortable with older or very elderly students going to college, but in fact they ignore a fundamental problem - college is for everyone, not just young people, and learning is not just for teenagers. Regardless of whether you are young or old, learning throughout your life is in line with the requirements of lifelong learning.

Scientists make progress in studying the history of volcanic activity in the Chang'e-5 landing area

Research on the thickness of basalt and its eruption rate in the Chang'e-5 landing area will help enhance people's understanding of the lunar volcanic activity and internal thermal evolution history.

Researchers from the Key Laboratory of Solar Activity and Space Weather at the National Space Science Center of the Chinese Academy of Sciences, in collaboration with researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences, Peking University, and Shandong University (Weihai), estimated the thickness of the basalt in the Chang'e-5 landing area, determined the formation sequence of the basalt units at the Chang'e-5 landing site and surrounding areas, and estimated the thickness of the underlying basalt units in the Chang'e-5 landing area.

Research based on thermochemical and kinetic models believes that the abundance of heat-generating elements in the Kreep terrane in the Ocean of Storms on the lunar front is the main reason why the lunar volcanic activity is still active in the late period. However, the latest sample research results show that the basalt in the Chang'e 5 landing area is not Kreep basalt.

The study proposes a possibility that the heat-generating elements in the Kreep terrane in Oceanus Procellarum do provide a heat source for the partially melted areas of the lunar mantle, but the magma may not have had time to fully mix with the Kreep components in the Kreep terrane in the process of rapidly rising from the lunar mantle to the lunar surface, resulting in the fact that no large amount of Kreep material was measured in the Chang'e-5 basalt samples.

Scientists make progress in brain-computer interface information processing technology research

Nowadays, more and more people suffer from stroke and motor paralysis due to the accelerated pace of life and stress, and this phenomenon is showing a trend of younger people. The loss of motor ability not only brings great pain to the patients themselves, but also brings serious burdens to their families and society.

Brain-computer interface is the key to the interaction between the brain and the outside world. It bypasses the peripheral nerves and establishes a direct connection between the brain and external devices for information exchange. How to convert brain intentions into commands to control external devices in real time and effectively is one of the key issues restricting the development of brain-computer interface technology.

To this end, Tang Fengzhen's research group at the Shenyang Institute of Automation, Chinese Academy of Sciences, conducted research on the decoding of scalp EEG signals and made progress. The researchers proposed a brain signal decoding method based on logarithmic Euclidean metric Riemannian geometry, which improved the efficiency of brain signal decoding while ensuring accuracy.

The researchers verified the proposed method on a variety of data sets and achieved good results in recognition speed and accuracy. The recognition speed is about 4 times faster than the EEG signal decoding method based on the affine invariant Riemann metric. In the test using the BCI Competition IV-2a public data set, the proposed method has a better recognition accuracy than the first place in the competition. The proposed method greatly improves the brain signal decoding speed and effectively reduces the delay in the execution of commands by the brain-computer interface system, which is of great significance for promoting the practical application of brain-computer interfaces in motor rehabilitation of paralyzed patients.

Blood type is related to stroke? This blood type is 16% more likely to

Recently, a meta-analysis conducted by a research team at the University of Maryland School of Medicine found that a person's risk of early stroke may be related to his blood type.

After controlling for sex and other factors, the researchers found that people with type A blood had a 16 percent higher risk of early stroke compared with people with other blood types, while people with type O blood had a 12 percent lower risk of stroke than people with other blood types.

However, the research team is still unclear why type A blood brings a higher risk of early stroke. They speculate that it may be related to coagulation factors, such as platelets and cells around blood vessels, and other proteins that play a role in thrombosis. Therefore, further research is needed to clarify the mechanism of increased stroke risk.

In addition, a limitation of the study is the relative lack of diversity in the participants. The researchers stressed that the increased risk of stroke due to blood type is not strong, so people with type A blood do not need to be overly concerned about early stroke, nor do they need to undergo additional screening or medical tests because of the above results.
