NO.1 New details of room temperature superconductor "PCPOSOS" released

On March 4, local time, at the March meeting of the American Physical Society (APS), Korean Professor Hyun-Tak Kim of William & Mary University in the United States, who had sparked discussions on superconductivity last year, announced the latest details of the so-called room temperature superconductor "PCPOSOS". Professor Kim released experimental videos of multiple samples and said that the partial suspension caused by the non-uniform magnetic field in the video is evidence of a type II superconductor (i.e., a room temperature and pressure superconductor).

Commentary: Room temperature superconductors can greatly reduce energy consumption and cost, and improve the efficiency of power transmission and storage. However, there are still some controversies and uncertainties about this research, and more experiments and verification are needed.

NO.2 New AI tool goes viral on GitHub platform

Recently, a AI new tool named DUSt3R has become popular on the Microsoft-owned GitHub platform. It can complete 3D reconstruction in just two seconds with only two pictures, without the need to measure any additional data. This AI tool quickly became GitHub's second hottest tool after it went online. According to a netizen's test, he took two photos and reconstructed his kitchen, and the whole process took less than 2 seconds. Some analysts believe that the tool demonstrates the broad application space of AIGC, and 3D is expected to be the next mode to achieve breakthroughs.

Commentary: The popularity of this tool reflects the development trend of AI, which is to expand from a single mode to multiple modes.

NO.3 Samsung to leverage Nvidia to improve chip yield

According to media reports, an EToday report shows that in the face of increasingly fierce competition in the semiconductor field, Samsung Electronics has decided to integrate Nvidia's cutting-edge technology "Digital Twin" into the production process to improve chip production efficiency and quality to narrow the gap with its competitor TSMC.

Commentary: This is a strategic move that meets market demand and technological development. In the future, it may help Samsung improve its competitiveness and innovation in the semiconductor field.

NO.4 Apple releases MacBook Air with M3 chip

On March 4, local time, Apple released a new MacBook Air with the M3 chip on its official website, which will be officially released on Friday (March 8). According to the price on the US website, the starting price of the MacBook Air with M3 chip and 13-inch screen is $1099, and the 15-inch is $1299. Apple's US website claims that the M3 chip integrates a faster and more efficient 16-core neural network engine, which, along with accelerators in the CPU and GPU, speeds up machine learning on the device, making the MacBook Air "the world's best AI consumer laptop."

Commentary: The new MacBook Air with the M3 chip supports more machine learning features, demonstrating Apple's valuing of AI.

NO.5 OpenAI competitor announces Claude 3 models

Anthropic, an AI startup backed by Google and Amazon, released the Claude 3 model family on March 4, local time. The family includes three models: Claude 3 Haiku, Claude 3 Sonnet and Claude 3 Opus, with the performance of the three models increasing in sequence. The company said that Claude 3 Opus outperforms OpenAI's GPT-4 and Google's Gemini 1.0 Ultra in various tests.

Commentary: OpenAI needs to take seriously the challenge posed by the Claude 3 model family, and this news also reflects the current innovation and fierce competition in the AI field.
