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.

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.

Antarctic Ice Core reveals changes in CO2 concentration over the past thousand years
On April 27th, Natural Geoscience (Nature Geoscience) magazine published an article entitled "links between atmospheric CO2, terrestrial carbon banks and climate in the past millennia" (Links between Atmospheric Carbon Dioxide, the Land Carbon Reservoir and Climateover the Past Millennium). According to the reconstruction data of CO2 concentrations over the past millennium, the main reason for CO2 concentration fluctuations on a time scale from decades to centuries is the feedback mechanism between climate and terrestrial carbon banks.

OECD: strengthen urban water management to ensure sustainable utilization of urban water resources
In April 2015, the Organization for Economic Cooperation and Development (OECD) released a report entitled "Water and cities: ensuring a sustainable future" (Water and cities: Ensuring Sustainable Futures), which aims to promote urban development and coordinated use of water resources and sustainable development in its member countries. OECD member countries are basically at a high level in terms of urban water management measures, and most residents have access to safe and reliable water supply services. The main risks faced by its member countries are to withstand floods, droughts, deterioration of water quality caused by urban growth, competition for water resources, water pollution caused by agriculture and climate change. There are also problems caused by aging infrastructure. Most OECD member cities need to solve their problems from the current situation of existing infrastructure and environment.
