37% Android phones store hidden dangers of monitoring users.

1, IBM released "the world's first 2nm chip"

Recently, IBM released the world's first 2nm chip promotional video. In 202 1 year, IBM created the world's first 2 nm node chip. Its smallest component is smaller than single-stranded DNA, the number of transistors is equivalent to 10 times that of trees all over the world, and its power consumption is basically the same as that of today's 7-nanometer chip, but its performance is improved by 45%. It has become the basis of future chip manufacturing for every chip manufacturer. After announcing the success of the research and development of the 5-nanometer design, it took IBM less than four years to achieve a technological breakthrough again. With the emergence of this breakthrough technology, a fingernail-sized 2-nanometer chip can hold as many as 50 billion transistors. The 2-nanometer design demonstrates the advanced scalability of semiconductors by using the nano-chip technology developed by IBM. This architecture is the first in the industry.

2, MediaTek exposed chip firmware vulnerabilities: 37% of Android phone storage monitoring users hidden danger.

Recently, Check Point obtained the control of MediaTek chip from a red rice Note 9 5G mobile phone running Android 1 1 and equipped with Tianji 800U chip. Check Point estimates that 37% of the world's smartphones have this vulnerability. Checkpoint security researcher slava? Makaui said, "In view of the popularity of MediaTek chips, we think it may become a channel for potential hackers to launch attacks." Malicious applications can program chips, make devices eavesdropping tools and run secret applications. MediaTek believes that these security vulnerabilities have not been exploited by hackers, and has released patch software to mobile phone manufacturers.

3. The first domestic full-featured GPU was successfully developed.

165438+1On October 25th, Moore Thread, a domestic chip startup company, announced that the first full-featured GPU chip in China had been successfully developed as scheduled, and at the same time, it completed a round of financing of 2 billion yuan. Moore Thread said that this domestic full-featured GPU has started to adapt to the domestic mainstream CPU and operating system, and will unite with a wide range of ecological partners to create a "China Perfect Experience System" based on domestic technological innovation, aiming at providing consumers and corporate customers with the best user experience.

5. The stretchable pressure sensor helps the flexible robot to achieve a new breakthrough.

According to the Memphis Consulting Group, the research team at the Pritzker School of Molecular Engineering (PME) of the University of Chicago recently found a solution to the above problems. They designed a new pressure sensor, which can be stretched to 50% while maintaining the same sensing performance. This pressure sensor is very sensitive. It can detect the pressure of a small piece of paper and respond to the pressure immediately. The researchers connected the pressure sensor to a flexible manipulator, which can get the pulse waveform-the dynamic pressure pattern generated by each pulse beat-from a person's wrist. This research result was published in the journal Science Progress on1October 24th, 165438. In addition, the researchers also applied for a patent for this technology.

6. The construction of China's first real-time remote sensing constellation will begin, and it will observe any part of the world in a few minutes.

According to CCTV news reports, China's first real-time remote sensing constellation will start construction, which will be composed of hundreds of low-orbit remote sensing satellites, forming a global coverage of earth observation capabilities. In particular, the observation efficiency will be greatly improved. After the networking is completed, satellite observation data in any part of the world can be obtained in a few minutes, while in the past, it often took hours or even days to obtain remote sensing satellite data. Yuan, technical director of the satellite operation industry of the Third Academy of Aerospace Science and Industry Group, said that this constellation is actually a whole in design. There are inter-satellite links between satellites, and multiple satellites can continuously observe the same area, realizing high-frequency and minute-level observation. In addition, China's first satellite Internet of Things-"Cloud Project"-is about to enter the stage of large-scale networking construction. The "Walking Cloud Plan" will build an Internet of Things constellation system consisting of 80 satellites, which will connect various information nodes or sensors of the global Internet of Things.

7.FCC opposes China Telecom's application to continue its business in the United States.

According to Reuters, on Wednesday, the Federal Communications Commission (FCC) asked a federal appeals court in the United States to reject China Telecom's application to continue providing services in the United States. Last month, the FCC revoked the business authorization of China Telecom in the United States. The FCC said that China Telecom "is influenced and controlled by the China government, and it is very likely that it will be forced to comply with the requirements of the China government under independent judicial supervision without sufficient legal procedures." In the past 20 years, China Telecom has been authorized to provide telecommunication services in the United States. In 20 19, the company has more than 335 million users worldwide. China Telecom, which also serves the China government in the United States, warned that the FCC's actions would force the company to "terminate its entire resale mobile service in the United States".

8. Osaka University develops nano-antennas for long-distance and ultra-secure quantum communication.

Recently, a research team of Osaka University introduced its newly developed nano-chip for long-distance and ultra-secure quantum communication in Applied Physics Express. By using surface plasmon antenna and electron excitation in quantum dots, this scheme can effectively irradiate photons on semiconductors. It is also compatible with the upcoming advanced technology, which is helpful to improve the transmission efficiency between quantum information carriers. Theoretical simulation shows that this technology is expected to improve the photon absorption efficiency to 25 times in the future. At present, the research team is planning to start from two aspects, one is to improve the alignment of light sources, and the other is to manufacture nano-antennas more accurately.

9. Nokia and Chubu Telecom, a subsidiary of KDDI in Japan, conducted the 5G Sub-6GHz SA test.

Recently, Nokia and KDDI subsidiary Chubu Telecom conducted the 5G Sub-6GHz SA test, and Nokia will provide its latest AirScale product portfolio and compact mobile unit (CMU) to support 5G indoor and outdoor connections. It is reported that the test will use the 5G local network independent of the traditional mobile network, and use the Sub-6GHz(n79)4.6-4.9 frequency band to enhance the capacity. The high frequency spectrum below 6GHz can support high capacity and extreme mobile broadband capability. While bringing users a smoother network experience, it greatly improves the efficiency of enterprise remote application, and can reduce the impact of network failures when disasters such as earthquakes occur, providing a technical basis for more future 5G use cases.

10, Jingxiong Expressway will set up intelligent lanes.

According to Beijing Daily, at present, the main project from the Sixth Ring Road to the city boundary of Xiong Jing Expressway (Beijing-Xiong 'an) has been basically completed and entered the stage of bridge deck pavement. The expressway will set up the first intelligent high-speed dedicated lane in China for testing unmanned driving. For the first time in China, Xiong Jing Expressway has set up an intelligent expressway lane on the inside. Intelligent lanes were originally used for vehicle-road collaborative application scenario testing, supporting unmanned buses and networked fleets to run on the road; In the long run, the vehicle-road coordination of all lanes in the whole section will be realized, that is, unmanned driving. According to the construction plan, the entire Xiong Jing Expressway (including the Sixth Ring Road to the city boundary and the Fifth Ring Road to the Sixth Ring Road) will be opened to traffic by the end of next year.
