Where is the endless food? the circular economy has a bright future!
In today's linear food system of "take it and throw it away", most valuable nutrients face the misfortune of entering rivers, landfills, incinerators or open-air garbage dumps, and less than 2% of the resources are used effectively. This not only endangers public health and increases carbon emissions, but also directly results in a cost loss of 5.7 trillion dollars a year.

The Academy of Sciences recommends the implementation of a solar geoengineering research program.
one Present situation of research and treatment of solar energy geoengineering The report considers three solar geoengineering measures: stratospheric aerosol injection (increasing the number of tiny reflected particles in the stratosphere to increase the reflection of incident sunlight); whitening of ocean clouds (adding particles to the lower atmosphere to increase the reflectivity of low clouds over the ocean); and cirrus thinning (changing the characteristics of high-altitude ice clouds to allow more infrared radiation to escape into space).

Report | World Economic Forum released major development trend: aim at circular consumption, there will be no more garbage in the future
"in order to feed and clothe ourselves in the way we live in the 21st century, we have overconsumed at least 56% of the biological carrying capacity of the earth." This is a sentence in the Earth Vitality report (Living Planet Report) jointly prepared by the Zoological Society of London and the World wide Fund for Nature in 2020. A large number of shocking data reveal that the relationship between human beings and ecosystems is fraught with problems. The relationship between human beings and the ecosystem has been fundamentally unbalanced.

The problem of how to turn a circle into a square has perplexed mathematicians for thousands of years.
The reason why this problem is difficult to answer is that it is not only a geometry problem, but also an algebra problem. In the problem of drawing with rulers and compasses, given a number of angles or length of line segments, the essence is to give some real numbers, while the rule of drawing with non-graduated rulers and compasses ensures the length of the angles or segments made, which is the combination of sum, difference, product, quotient and square root of a given real number. As a result, each ruler drawing problem actually corresponds to an algebraic problem.

Carbon Brief reviews climate articles with the highest media attention in 2020
In first place was the article "temporary reduction in Global carbon dioxide emissions during COVID-19 's mandatory restriction period" (Temporary Reduction in Daily Global CO2?Emissions During the COVID-19 Forced Confinement) published in Natural Climate change (Nature Climate Change), with an Altmetric score of 6174. Researchers from the University of East Anglia (University of East Anglia) in the UK and Stanford University (Stanford University) in the United States have designed an alternative method to re-analyze the comprehensive data of energy, activities and policies up to the end of April 2020, based on the corresponding restriction index (confinement index, CI) to estimate the change in daily CO2 emissions compared to 2019. The study found that global CO2 emissions by early April 2020 were 17 per cent lower than the 2019 average as a result of the government's policy to prevent the spread of the COVID-19 epidemic. The study was mentioned by 715 online news articles, 63 blogs and more than 4000 tweets, including the Washington Post, the Financial Times, Reuters, New Scientist, the Guardian, BBC News, the Daily Mail, the Independent, the Daily Telegraph and Sky News.

Chemical cycle: will it be a "panacea" for the disposal of waste plastics?
Zhu Xingxiang, president of the China Circular economy Association, has exposed the cruel truth of plastic recycling: only 9 per cent of the world's 9 billion tons of plastic products are recycled. Most plastics end up in landfills or incinerators. Compared with the recycling rate of waste paper and scrap steel, the recycling proportion of plastics in China is astonishingly low. All kinds of plastics in life are thrown into roadside trash bins and mixed with metal and waste paper, but most of the metal and waste paper can be recycled, and most plastic waste can only go to landfills. We are in urgent need of effective recycling methods to deal with waste plastics.

Physics The latest LHAASO experiment verifies the correctness of space-time symmetry in Einstein's theory of relativity. But there are very high-energy processes in celestial activity. When the high-altitude large cosmic ray experiment LHAASO in Daocheng, Sichuan Province was not fully completed in 2021, it detected the gamma ray photons with the highest energy known to mankind, with an energy of 1.4 × 10 GeV. The LHAASO team used its observed high-energy gamma-ray cases to test the Lorentz symmetry. The experimental results increase the breaking energy scale of Lorentz symmetry by about 10 times, which is the strictest test of this kind of Lorentz symmetry, and once again verifies the correctness of Einstein's relativistic space-time symmetry. The relevant results are published in the latest issue of physical Review KuaiBao. (Institute of High Energy, Chinese Academy of Sciences)
