Major benefits!China discovered the "big kill move" in suppressing the new crown!2 trillion giants voiced, the United States loosened?What is the curse of 8 energy executives of Russia?

Close to the weekend, let's take a look at important news with us!

According to the website of the National Nano Science Center and the South China Morning Post, a research team in China has developed a nanomal material that can find the SARS-COV-2 virus in live cells and remove it. Researchers say that unlike most of the existing COVID-19 drugs, the material can inhibit the infections of all major variants, including Alpha, Beta, Delta, and Omitron, which has high biological safety. The research results were published on Nature Nanotechnology in August. This may be a big killing against the new coronal virus, and it is also a hope for the current epidemic prevention and disease.

At present, the impact on the market is mainly from two aspects: one is the epidemic and the other is international disputes. After reporting the United States yesterday, the United States was ruthless to the exit of chips, and today we ushered in a big reversal. 2 trillion giants said on Thursday that the US government will allow it to continue to develop its H100 artificial intelligence chip in China.

But Russia is still not quite peaceful. According to the Russian -sponsored news media International Telecommunications Agency, Lavil Marginov, chairman of Russian oil giant Luke Petroleum Corporation, fell from the window of the Capital Central Clinical Hospital on Thursday. Russian energy executives have died in a curse. The death of Marginov is also the eighth Russian energy executives of Russia's sudden death.

Discover the new crown "big kill"

Although there is no drug that can eliminate the new coronal virus, I hope it still exists.

According to the South China Morning Post, a research team in China has developed a nanomal material that can find the SARS-COV-2 virus in live cells and remove it. Researchers say that unlike most of the existing COVID-19 drugs, the material can inhibit the infections of all major variants, including Alpha, Beta, Delta, and Omitron, which has high biological safety. A researcher involved in the research said: "This may be a very promising therapy that can fight this epidemic in the future." The results were published on Nature Nanotechnology in August.

A reporter from securities firms also discovered the news on the website of the National Nano Science Center. On August 22, the cooperation results of the cooperation results of the China Academy of Sciences Shenzhen Advanced Technology Research Institute and the National Institute of High-Energy Physics and the Kunming Institute of Chinese Academy of Sciences-a new broad-spectrum anti-new crown nanomaterial, with A Nanomaterial Targeting the Spike Protein Captures Sars-Cov-2 Variants and Promotes Viral Elimination is published in the nano-international journal "Nature-Nano Technology". Nanomical materials are very small -one nanometer is equal to one billion yuan. The structure of this material is called CIPS, because it is made of copper, pheasant, phosphorus, and sulfur -in the form of nanospin, about 200 nanometers, and about two virus particles.

Generally, the SARS-COV-2 virus invades human cells with the help of spiny protein on its surface. Casting protein is combined with the ACE2 protein on the surface of the human cell, just like a key lock, which allows the virus to invade the host cells.

However, CIPS can selectively combine with the virus's spiny protein to prevent the infection process. Once the CIPS captures the virus, it will form a stable complex. The complex was then identified and eliminated by the host's macrophages. Macrophages are large white blood cells that digest foreign substances in the human immune system. "Experiments show that CIPS can effectively inhibit the infection of cells, organs and mice, and effectively relieve mice inflammation caused by mice caused by SARS-COV-2 infection." The paper mentioned.

The effectiveness of vaccines and antibodies used to fight SARS-COV-2 decreased on variants such as OMICRON. Although most antibodies are designed to bind to a single position on the virus, mutations in the Omitron variant may change the surface structure. CIPS can be bound to multiple sites at the same time. So far, more than 1,000 new coronary virus mutations have been found. Although the Chinese team cannot test CIPS materials on all strains, they find that CIPS is very effective for all variants that pay attention to -Alpha, Beta, Delta, and Omitron.

Good biocompatibility is the prerequisite for the safety application of nanomaterials. Researchers studied the absorption, distribution, metabolism and excretion of CIPS in mice, and found that the material had high biodegradability. "Mouse inhaled CIPS by nasal drops. After 7 days, the lungs of the mice almost completely eliminated CIPS." The study said.

The National Minnan Science Center stated that the research and development of nano -materials that have a broad -spectrum antiviral activity have been developed for the new crown virus and various mutant strains. Essence The continuous mutation of the new coronal virus has reduced the effectiveness of existing drugs and vaccines. This research is expected to provide new strategies for the currently -needed broad -spectrum anti -new crown drug research and development. The biodegradability and biological safety of CIPS nanomaterials indicate that it is a nanomaterial with good conversion and application value, but it needs to be tested by a series of clinical trials. In addition, CIPS nanomaterials have the high affinity of the new coronal virus, and they also have the potential to use as a decontamination agent and surface coating material to inhibit the spread of the new coronary virus. Big reversal! Is it loose?

Nvidia said on Thursday that the US government will allow it to continue to develop its H100 artificial intelligence chip in China. It is a victory for the company after a warning of new export restrictions on Wednesday that it may hinder its business in the country.

Nvidia said in a document submitted to the US Securities and Exchange Commission on Wednesday that the US government is restricting to sell high -performance artificial intelligence chips A100 and H100 for servers for servers for servers. The sales of these two chips in these markets are still restricted, although it can still develop H100 in China. Nvidia predicts that new export restrictions will cause $ 400 million in income this quarter.

The company's stocks fell nearly 8%in Thursday's transactions. However, Nvidia stated in a document on Thursday: "The U.S. government has authorized the export, re -export and domestic transfer required to continue Nvidia or the company's development of the H100 integrated circuit."

H100 is an AI chip that NVIDIA is about to launch. It was previously expected that the chip would be shipped at the end of this year, and its part of its development occurred in China. A100 is an old model that has been shipped for three years. They are graphics processors that can be used for super computing and artificial intelligence.

Russian Energy Senior Case Curse

In addition, the profession of Russian Energy Corporation seems to have become a curse.

On Thursday, Russian oil giant Luke Petroleum Corporation, Ravier Marginov, died in a hospital in Moscow, which seemed to marked the eighth time the Russian energy executive suddenly died in unusual circumstances this year. According to the Russian -sponsored news media International Telecommunications Agency, Marginov died from the window of the Central Clinical Hospital of the Capital.

In late January this year, Russian natural gas giant Russia's Gazprom executives of Gazprom, Leonid Shulman, were found in a bathroom in a hut in a hut in Leninsky Village.

On February 25, another Gazprom executive Alexander Tyulakov was found to die in the same village as Shulman, and this time was in the garage.

On February 28, Russia's oil and natural gas billionaire Mihayer Waterford, who lived in England, was found in the garage of his rural manor.

On April 18, former Vice President of Russia's Natural Gas Industry Co., Ltd. Vladeslav Avayev was found to die in the apartment in Moscow, and his wife and daughter died.

On April 19, the former vice chairman of Russia's largest liquefied natural gas producer NOVATEK was found to die in a holiday house in Spain. His wife and daughter were discovered together, and they had died.

In May, Alexander Subbotin, a former executive of Billionaires and former executives of Luke Petroleum, was discovered in the basement of a country villa in a rural villa in Moscow.

In July, the chief executive and founder of the shipping contractor of the Russian Natural Gas Industry Co., Ltd. provided the service officer and founder of the shipping contractor, Yury Voronov, was in his swimming pool in Leninsky, Leninsky, Discover the obvious gunshot wounds.
