A major breakthrough! Mainland China has mastered the advanced control technology of controllable nuclear fusion with high constraints
According to CNNC's WeChat public account on August 26, on the afternoon of August 25, the new generation of artificial sun "China Circulation III" made significant scientific research progress, for the first time realized the high confinement mode operation under 1 million amperes plasma current, once again refreshed the operation record of the continental magnetic confinement fusion device, broke through the key technical problems such as plasma high-current high-confinement mode operation control, high-power heating system injection coupling, advanced filter position control, etc., which is an important milestone in the development process of continental nuclear fusion energy. It marks an important step towards the operation of high-performance fusion plasma in continental magnetic confinement nuclear fusion research.
In order to achieve fusion energy, it is necessary to upgrade the plasma synthesis parameters to fusion ignition conditions. The high confinement mode (H-mode) in magnetic confinement nuclear fusion is a typical advanced operation mode, which has been selected as the standard operation mode of the International Thermonuclear Experimental Reactor (ITER) under construction, which can effectively improve the overall confinement performance of the plasma and improve the economy of future fusion reactors.
As a cutting-edge disruptive technology facing the major needs of the country, controllable nuclear fusion has outstanding advantages such as abundant resources, environmental friendliness and inherent security, and is one of the important ways to finally solve the human energy problem, and is of great strategic significance to the mainland's economic and social development and national defense industry construction. Controllable nuclear fusion is an important part of the three-step strategic system of "hot reactor-fast reactor-fusion reactor" for the development of mainland nuclear energy, and is a key scientific and technological variable to solve national energy needs, promote the realization of the "dual carbon" goal, promote the construction of a new energy system and ensure national energy security.
On the basis of realizing the operation of million-amperre plasma current high confinement mode, the new generation of artificial sun "China Circulation III" team will further develop core technologies such as high-power heating and current drive, and advanced plasma operation control, realize core-level plasma operation, study cutting-edge fusion physics, and lay a solid foundation for mainland to carry out fusion combustion experiments and build fusion reactors independently.
WHO: Risk of poliovirus transmission remains a 'Public Health Emergency of International Concern'
According to Xinhua News Agency, the World Health Organization announced on the 25th that the risk of transmission of polio (polio) virus still constitutes a "public health emergency of international concern".
The WHO Emergency Committee has held a relevant evaluation meeting on the 16th. WHO issued a statement on the 25th, saying that after discussion, the committee has put forward a series of recommendations to WHO Director-General Tedros Adhanom Ghebreyesus on the current situation of virus transmission and future prevention and control, and the Director-General adopted the recommendations and decided on the 23rd that the risk of transmission of poliovirus still constitutes a "public health emergency of international concern".
According to WHO, Pakistan and Afghanistan have reported 1 and 5 new cases of wild poliovirus infection since the Committee's last assessment meeting; In Africa, coordinated action by several countries has improved since the detection of wild poliovirus locally in February 2022. Mozambique has not reported any new cases since 10 August 2022, but the Committee concluded that previous assessments did not rule out the possibility of continued wild poliovirus transmission in Malawi and Mozambique.
For "vaccine-derived" poliovirus type 2, the Committee said that although the number of cases infected with the virus continues to decline, the risk of international transmission remains high. According to reports, when a community's immunity to poliovirus is reduced to a certain level, the attenuated virus in oral vaccines can spread for a long time, resulting in "vaccine-derived poliovirus transmission".
The Committee considers that the risk of international spread of poliovirus remains due to the risk of cross-border transmission of poliovirus, inadequate surveillance in some areas, and inadequate vaccination in some areas. The Committee called for enhanced surveillance of the virus in all its aspects.
Polio, commonly known as polio, is an acute infectious disease caused by poliovirus that mainly affects children under 5 years of age. Patients may present with fever, headache, muscle pain, vomiting, and in severe cases, paralysis or death. There is no cure for the disease, vaccination is the most cost-effective way to prevent it, and oral vaccines made with live attenuated virus are one of the most commonly used polio vaccines.
A magnitude 4.6 earthquake struck off the coast south of Yamaguchi Prefecture, Japan
According to CCTV news client reported on August 26, at about 22:29 local time, a 4.6-magnitude earthquake occurred in the offshore waters south of Yamaguchi Prefecture, Japan, with a maximum seismic magnitude of 3 and a focal depth of 80 kilometers.
Partial daily price shop display: raw materials are not raised Japan
In response to the discharge of Japan's nuclear-contaminated water into the sea, the General Administration of Customs of the mainland issued an announcement that from August 24, the import of aquatic products (including edible aquatic animals) originating in Japan will be completely suspended.
According to CCTV Financial reports, some Japanese food stores said that the raw materials did not come from Japan.
At the three Japanese food stores in Shanghai, the per capita consumption is more than 250 yuan, and the clerk said that the business has been basically unchanged in the past two days, but many consumers do ask about the origin of the raw materials, and they say that the raw materials currently used do not come from Japan.
In fact, since the beginning of last month, the General Administration of Customs of the mainland has required a high degree of vigilance and strengthened supervision of imported food from Japan. Recently, the Shanghai Jinshan District Market Supervision Bureau has carried out surprise inspections of relevant imported foods for some supermarkets and restaurants, clearly requiring relevant business units not to sell food prohibited by mainland customs.
At a Japanese restaurant in Shenzhen, Guangdong Province, fresh Ezo scallops and sea old shrimp were newly stocked, and the person in charge said that these ingredients came from domestic origins.
UBS: Bullish on global energy stocks
In financial markets, UBS said in its latest report that it is optimistic about the outlook for global energy stocks.
It said better-than-expected global economic growth, coupled with continued tight supply, helped fuel prices rise. Recently, the price of Brent crude oil has risen about 20% from the low reached in June. However, energy stocks have yet to keep pace with the rise in oil prices. UBS is now taking a more positive outlook for energy stocks over the next 6 to 12 months. It is believed that this lagging sector will recover, which will bring potential investment opportunities. UBS upgraded global energy stocks to "bullish."
