The National Natural Science Foundation of the United States released the report "The United States is the Cornerstone of Global Science and Engineering"
According to the News of the National Natural Science Foundation (NSB) on January 13, the National Natural Science Foundation of the United States released the report "The United States is the Cornerstone of Global Science and Engineering". The report notes that the 2022 U.S. Science and Engineering (S&E) metrics show that no country is globally leading in all aspects of S&E, and the United States can no longer achieve full leadership, and the United States must become the cornerstone of the global S&E ecosystem. To this end, the United States must improve its visa system, welcome foreign scientific and technological talents, increase research and development funding in engineering, computing, and mathematics, increase investment in basic research, set norms for key and emerging technologies in knowledge- and technology-intensive industries, and strengthen cooperation in international publications and infrastructure.
The U.S. is reviewing national security risks in Alibaba's cloud computing division
According to the news on the official website of Reuters on January 19, the Biden administration is reviewing the cloud business of e-commerce giant Alibaba to determine whether it poses a risk to U.S. national security. The survey focused on how Alibaba stores data from U.S. customers such as personal information and intellectual property, and whether the Chinese government has access to that data. The investigation is led by the Commerce Department's Intelligence and Security Office, which could ban or restrict transactions between U.S. companies and Internet, telecommunications and technology companies from "foreign rival" countries such as China, Russia, Cuba, Iran, North Korea and Venezuela. U.S. regulators may ultimately choose to force Alibaba to take steps to reduce the risks posed by its cloud computing business, or to ban the use of the service altogether from Americans at home and abroad.

Apple and Google say antitrust bills will hurt consumer safety
According to Engadget news on January 18, Apple and Google have raised objections to the U.S. Senate's proposed The American Innovation and Choice Online Act and The Open App Markets Act, arguing that the antitrust bill will harm consumer safety. In a letter to lawmakers, Apple said the antitrust bill under consideration by the Senate would force the company to open up its app download path, which would increase the risk of iPhone users facing security breaches. Kent Walker, Google's president and chief legal officer for global affairs, made a similar argument, arguing that the antitrust bill would weaken Google's ability to integrate automated security features into its services and hurt the competitiveness of U.S. companies.

The UK government has announced a formal crackdown on "misleading" crypto ads
According to the news of Engadget network on January 18, the British government is planning to legislate to bring the promotion of crypto assets into the scope of financial promotion supervision. This will ensure that any cryptocurrency advertising will follow the same regulatory standards as stock and insurance product promotions to prevent consumers from falling into scams. The UK government says about 2.3 million people in the country own crypto assets. While the popularity of crypto assets is on the rise, the level of knowledge that potential investors know about them is declining. This means that people may not be fully aware of the risks involved in investing in them.
Israeli police use Pegasus spyware to spy on politicians in the country
According to the news of Engadget network on January 19, the Israeli police, in the absence of search warrants and judicial supervision, used the NSO Group's Pegasus spyware without authorization to invade the electronic devices of Israeli citizens. According to local Israeli media, the targets of the invasion included opposition leaders in direct confrontation with Benjamin Netanyahu (former Israeli prime minister), former government employees and a person close to high-level politicians, and police even used Pegasus to track and monitor protesters during the former prime minister's tenure. As more and more reports reveal that Pegasus spyware is secretly spying on journalists, political activists and others. In December 2021, reports revealed that Pegasus was spying on U.S. State Department officials, and in November 2021, Apple filed a lawsuit against the NSO Group.

German researchers have developed methods to achieve accurate and efficient RNA editing without the need for foreign proteins
According to the news of Bioworld on January 17, a research team at the University of Tübingen in Germany has developed a cluster-like guide RNA "CLUSTER gRNAs". This CLUSTER design enables gene-encoded gRNAs with a high degree of sequence flexibility, can bind to their target mRNA in a multivalent manner, eliminating the need for foreign proteins, enabling high-precision and efficient editing, and targeting sequences that were not accessible using previous gRNA designs. CLUSTER gRNAs can be genetically encoded and delivered through viral vectors and efficiently edited in multiple cell lines. In cell culture, CLUSTER gRNAs enable targeted editing of endogenous transcripts with up to 45% efficiency, and in vivo, CLUSTER gRNAs are delivered to mouse livers by hydrodynamic tail vein injection with editing efficiencies of up to 10%. The CLUSTER approach opens up new avenues for drug development in the field of RNA base editing. The research was published in the journal Nature Biotechnology.
Japan conducts the world's first human trial of spinal cord iPS stem cell therapy
According to the news of Bio World on January 17, Keio University in Japan has successfully transplanted iPS stem cells into a spinal cord injury patient, which is the first human clinical trial of its kind and a breakthrough in stem cell therapy. By extracting patient cells for in vitro culture, the researchers used iPS technology to induce these cells into a variety of desired cells that could use their replication capacity to repair damaged tissues or organs. It is reported that the research team has surgically transplanted more than 2 million iPS-derived neural stem cells into the spinal cord of patients with spinal cord injury. An independent committee will monitor patients for up to three months to determine the safety of transplantation methods, whether trials can proceed safely, and whether similar stem cell therapies can be performed on others.
New research in Virtue has found that DNA mutations do not occur randomly or will change the perception of evolution
According to cnBeta news on January 17, a new study by the Max Planck Institute for Biological Research in Tübingen, Germany, and the University of California, Davis in the United States, shows that DNA mutations do not occur randomly. Random mutations in DNA are one of the core assumptions of Darwin's theory of evolution, and this study shows that the pattern of DNA mutations is not only very non-random, but also non-random in a way that favors plants. The discovery offers a whole new perspective on mutation and evolutionary theory, with far-reaching implications, helping to predict the best genes for breeding and helping scientists identify disease treatment targets.
American scientists have developed the first AI breast cancer diagnosis system that can explain the results
According to the News of China Science and Technology Network on January 18, scientists at Duke University in the United States have developed a new artificial intelligence (AI) platform that can analyze potential cancerous lesions in mammogram data. The scientists trained the new AI using 1,136 images taken from 484 patients in the Duke University health system and tested the results. The artificial platform can accurately explain and demonstrate the process of its conclusion and the relevant theories on which it is based, helping healthcare workers to make better medical decisions.
