John Bohannon, an American popular science journalist, began to publish Doctor in 2008 under the sponsorship of Science and AAAS. Many scientists and artists were invited to be the judges of the "Shake Your Doctor" activity. According to their scientificity, artistry and creativity, champions in the fields of physics, chemistry, biology and social sciences will be selected, and a number of champions will be selected from them, and these "dancing champions" will also receive bonuses ranging from 500 to 2,000 dollars.

Although COVID-19's disease (coronavirus pneumonia-19) continued to spread in 20 19, the organizers did not stop there. This year (202 1), we joined the coronavirus pneumonia-19 group to encourage scientific dancers in all fields. ) try to speak out for related questions. Now, let's review this year's award-winning works!

Social Science: Is Science Difficult? Jump until you understand! Science is difficult? Jump until you understand! The research theme presented by the University of Graz in Austria is to compare how different teaching techniques are used in primary schools and how they affect pupils' learning.

If one day, the way primary school teachers teach becomes driving dance of various sects, how do you think children will learn? It seems that performing teaching in performing arts class can make students learn better than traditional teaching methods?

Follow "doctor, jump up!" This activity seems to have the same effect.

In the film, three teachers and students, with exaggerated expressions and love of action, first demonstrated the three steps of learning new things by action, namely naming, positioning and representation. In other words, we must be able to describe the name, position and appearance of an object in order to be considered as having learned something.

The research team divided the students into two groups, receiving traditional teaching and performance teaching respectively.

In the fragments of traditional teaching, teachers and students only exchange knowledge through oral expression, and teachers also give feedback and reflection, which is probably the usual way in our class. In exhibition teaching, children need to "describe" a thing or thing through various actions, including pantomime and imitating things in pictures. And the teacher will not give any feedback during the process.

What kind of magic does acting teaching have? Besides fun, can it really strengthen students' descriptive ability? Hurry and follow the teachers and students in the film. Get up. Come (? )

Physical S.H.E. depends on how Tiantuan talks about atmospheric science and physical S.H.E., and how Tiantuan talks about how atmospheric science can sing and dance. The team of Helsinki University in Finland has released How Molecular Groups in the Atmosphere Gather, Combine and Stabilize, which not only won the championship, but also made a debut in the momentum of the film and the brainwashing degree of songs.

Molecular clusters in the atmosphere will affect the formation of clouds and rainfall. In the prologue, there are dancers flying around in the air, symbolizing various gas molecules in the atmosphere. Among them, gaseous precursors such as ammonia, DNA, hyperoxia compounds (HOM), sulfuric acid and water will form secondary organic aerosol. They will become molecular clusters after collision polymerization, and eventually become cloud condensation nuclei to which water molecules can attach, and then develop into cloud droplets.

However, not all molecules can succeed, they will collide with each other.

Therefore, using the knowledge and technology of chemistry, physics and computer, the research team tried to simulate the stable molecular cluster structure in the configuration space.

In addition, they arrange molecules in different ways and design programs to explore them. They put the collected data into a more advanced model for analysis, and then used ACDC (Atmospheric Cluster Dynamic Code) to predict the formation rate of clusters, thus analyzing the atmospheric conditions suitable for the development of molecular clusters.

Although this film does not explain too many experimental details, it is really amazing in terms of the fit between the lyrics and the picture.

The actor who was delayed by the chemist played the atom for the first time and was picked up by the chemist. I got started playing with atoms for the first time, and then the unique chemistry prize was won by Dr. Mikael Minier, a software engineer at MIT. His theme is to replicate methane monooxygenase with bionic ligands, and to deeply study the reaction and state of molecules in solution.

Because of the strong C-H bond, the process of methane oxidation to methanol is quite difficult. And we can highly oxidize ferrous iron (Fe2+) contained in methane monooxygenase with oxygen to form a very strong oxidant, thus successfully delivering methane to Bai Wan! (error)

In order to analyze the process of methane oxidation by methane monooxygenase, Minell used biomimetic ligands and iron to form a double iron complex crystal, and reduced the structure of Fe2+ active site, and then began to study whether there were other unstable intermediates in the chemical reaction. Whether Minel's experiment is successful or not, whether it's Mr. Iron Atom who dances mechanically in a red and blue coat or the nuclear spin of a windmill, every role is super promising, which allows us to understand chemical changes from the perspective of atoms.

Biology Group: Do you think I'm tired of plastic? You think I'm tired of plastic? Fanon Julienne, Ph.D. in Physiology, University of Le Mans, France, and others introduced "photodegradation of plastic materials" in a way similar to music.

The award-winning works of the biological group with a rather literary overall style, from grandma telling stories to children, are very attractive in every link, from the sketch font of the introduction, the colored pencil drawing with catalog function to the Greek fairy tale-like character setting.

In order to show the aging process of plastics under various environmental conditions, the dancers played the roles of the sun, water molecules, and molecular chains of polyethylene (PE) and polypropylene (PP) arranged in different positions, and danced enthusiastically to restore the interactive state between plastics and the environment.

For example, if the plastic is exposed to ultraviolet light, its molecular chain will be broken and react with oxygen in the air, which will lead to the hardening and shrinkage of the plastic surface. Water will reduce the rigidity of plastic in water and make it easier to crack. In addition, different crystal forms will also produce different aging cracking results and cracking directions.

The virus that caused coronavirus pneumonia-19 also showed you plastic jump, plastic jump, plastic jump after virus jump ~

The virus that caused coronavirus pneumonia-19 also showed you the film released by Oregon State University, introducing the research on virus nucleocapsid protein, hoping to find a way to block viral RNA replication.

At the beginning of the film, a woman dressed in black spins and dances gracefully at the seaside. She is the core-shell protein in the virus. In the virion, the genetic material RNA of the virus is connected with the core-shell protein. If we want to understand the structure and replication mode of virions, we must know more about core-shell proteins.

In the choreography of dance, the creator pays great attention to the hard-core dance style and feminine figure, respectively interpreting protein with strong structure and fixed in a specific position, and disorderly protein with flexible structure.

The nucleocapsid protein of novel coronavirus, which caused COVID-19's disease (coronavirus pneumonia-19) in 20 19, also contained some disordered proteins. With the help of RF pulses in nuclear magnetic resonance, these are jumping to the irrational protein and starting to spin, so that researchers can understand the structure and movement of protein.

After that, we can adjust protein by mutation or post-translational modification (PTM) technology, understand how these foreign substances affect protein and its function, and develop drugs to prevent protein from linking with RNA and limit the ability and replication of the virus.

Who says scientific papers can only be "on paper"? Instead of listening to scientists chew on a bunch of equations, calculation models and gobbledygook math problems, it is better to enjoy their dance or go down and dance together!
