Brain-Computer Interface: A Revolutionary Technology Expanding the Frontiers of the Human Brain and the Future of Neurosurgery

Zhao Jizong — 2025-02-28

The brain-computer interface (BCI) is not merely an advanced technology but also represents a profound revolution spanning neuroscience, artificial intelligence, computer science, philosophy, and sociology. The core value of BCI lies in its ability to break through the informational barriers between the brain and the external world, endowing humans with novel capabilities for information interaction and propelling the evolution of an intelligent society. As a disruptive technological innovation, BCI fundamentally alters the way humans interact with the world, and its applications will profoundly influence our understanding of cognition, consciousness, and even self-existence. For neurosurgery, BCI is not only a revolutionary therapeutic tool but also an opportunity to reshape traditional medical paradigms. From repairing neural damage to modulating brain functions, from enhancing human intelligence to shaping the future of human-machine integration, BCI offers unprecedented possibilities for neurosurgery. The development of this technology not only aids in a deeper understanding of brain functions but also provides robust support for future intelligent healthcare. The impact of BCI extends far beyond medicine, influencing the transformation of future computing paradigms, the proliferation of intelligence augmentation, the scrutiny of social ethics, the deployment of national strategies, the dynamics of economic development, and the safeguarding of national security.

Zhang Shangzhe — 2025-03-10

This paper explores the impact of quantum computing on modern information security technologies, especially the threat to traditional encryption methods. The parallel processing capability of quantum computing and Shor algorithm make traditional encryption methods face the risk of being cracked. To address this challenge, this paper introduces novel cryptographic methods based on quantum computing, including quantum walking (QW) and quantum entanglement based cryptographic schemes, as well as quantum attack-resistant cryptographic algorithms (PQC). The computing principles, advantages and disadvantages of NTRUEncrypt and Lattice-based encryption algorithms are discussed in detail, and the application and prospect of these new encryption methods in information security are analyzed.

Wang Weilong — 2025-03-05

As the scale of quantum bits expands,manual calibration of quantum bits becomes costly and inefficient.Therefore,the automation of quantum measurement and control is imperative.A frame-work for automated quantum measurement and control is constructed in this work,including 3 modules such as measurement and control experiment,data processing and decision judgment,and 4 databases such as measurement and control experiment library,data processing function library,measurement and control experience library and measurement and control database.The automated calibration of single-qubit properties is completed based on this framework.The calibration of readout gates and single-qubit gates for 24 quantum bits is accomplished in a total of 2.7 h,averaging 6.75 min per qubit.An average single-qubit gate fidelity of 99.28%and a readout fidelity of 78.6%is achieved.

[Objectives] Magnetic confinement fusion is regarded as a critical solution to future global energy challenges. As the central component of magnetic confinement fusion devices, magnets play a crucial role in generating and sustaining plasma stability. A review of the magnetic system structures and specifications in representative magnetic confinement fusion devices worldwide was provided.

The structure and performance parameters of magnetic systems in various typical fusion devices were summarized systematically. Additionally, the technical challenges in magnet development were explored and an outlook on future development trend was offered. [Conclusions] Advances in magnet technology are vital for enhancing the performance of fusion devices and accelerating the commercialization of fusion energy. With the increasing application of high-temperature superconducting materials and continuous optimization of magnet designs, the practical realization of fusion energy is becoming increasingly feasible.

Site-specific editing of the cysteine transferase (CYS) gene in tobacco using the CRISPR/Cas9 technology

Li Yun — 2025-03-08

In order to study the effects of cysteine transferase (CYS) gene on the growth, development and anthocyanin synthesis in tobacco, we established CRISPR/Cas9 gene editing system in tobacco and constructed a double target CRISPR/Cas9 gene editing vector P35S-H-CYS. CYS tobacco mutant lines were obtained by Agrobacterium- mediated genetic system, the CYS gene knockout effect was tested by base sequencing and RTqPCR, the mutation types of target genes were analyzed. Sequencing results showed that 3 mutant lines had gene mutations at target sites, including base insertion and base replacement. Target site 1 could bind to target site more effectively, and target site 2 produced two bases mutations, both synonymous mutations of amino acids. RTqPCR results showed that the relative expression level of CYS gene in mutants were significantly lower than the wild type tobacco (P< 0.01). Compared to wild type, the multiple of gene transcription levels were 0.31, 0.45 and 0.34. The knockout ofCYS gene had no significant effect on tobacco plant height and leaf shape, but the anthocyanin content in the mutant tobacco were increased in different degrees. The content of anthocyanin in CYS-1 mutant was 1.3-fold, which was significantly higher than that of wild type (P<0.05). These results indicated that CYS gene can inhibit anthocyanin synthesis, which was consistent with the previous transcriptome analysis results. In this study, CRISPR/ Cas9 gene editing technology was used to design two target sites for targeted editing of CYS gene. Using tobacco as the transformation receptor provided an important material basis for further study of the function of CYS.
