Has scientific development slowed down today?
According to the report of the Natural Science Foundation of the United States, the world's scientific research output grew at an average annual rate of about 3.8 per cent from 2008 to 2018, based on the number of peer-reviewed scientific and engineering journal papers and conference papers. By 2018, the "output" had exceeded 2.5 million. In terms of the number of papers published, the scale of scientific research today is much larger than in the past. However, after analyzing a large number of published papers, a study published in the Proceedings of the National Academy of Sciences found that the large number of papers published does not reflect the development of science, on the contrary, they even hinder the development of science.

Health Antimicrobial resistance has become one of the leading causes of death worldwide. Antimicrobial drugs (Antimicrobial), including antibiotics, antiviral drugs, antifungal drugs and antiparasitic drugs, are used to prevent and treat human, animal and plant infections. However, these microbes can develop resistance and resistance to the drugs that treat them, that is, antimicrobial resistance (Antimicrobial resistance,AMR). Recently, a study published in the Lancet said that AMR has become one of the leading causes of global death and may be more serious than the threat posed by HIV or malaria.

Dozens of scientists jointly opposed the use of "artificial volcanic ash" to block out the sun to cool the earth.
On January 17, more than 60 international policy experts and scientists collectively spoke out about the potential dangers of geoengineering projects to lower the earth's surface temperature to slow global warming, and called on the government to stop such projects.

This underground fire has been burning for 6000 years.
In Australia, there is a national park called the Burning Mountain Nature Reserve (Burning Mountain Nature Reserve), four hours' drive from Sydney to the north. As the name says, underground here, a fire is burning and has been burning for thousands of years.

Astronomy Webb telescope reaches L2 orbit The Webb Space Telescope completed its final heading correction and entered the orbit of the second Lagrange Point (L2), which is about 1.5 million kilometers from Earth, at 2 p.m. eastern time on January 24, NASA reported. At present, the primary mirror and secondary mirror of the Webb telescope have been completed. After the telescope enters the L2 point orbit, engineers will begin a three-month complex debugging process to adjust the optical system of the telescope to a precision close to nanometer. The Webb telescope is expected to take the first image of the universe this summer.

There is no news in the scientific community today. Maybe this is the biggest news.
If a scientific study brings new discoveries, then its value is self-evident. However, behind these glamorous studies, many studies that have not found significant results are slightly lonely and do not even get the opportunity to be published, although they are also of great value to the development of science. With the joint efforts of scientists and the academic publishing community, this situation is changing.

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.

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.

These people never feel full, but the problem lies in their cerebellum.
Prad-Willie syndrome (Prader-Willi syndrome) is a rare genetic disease in which people never feel full. This lack of satiety can lead to severe obesity, which in turn leads to life-threatening diseases. Although the fist-sized cerebellum has never been linked to hunger before, scientists have found that the cerebellum plays a key role in regulating satiety in patients with Prad-Willie syndrome.
