第二届“香港世界青年科学大会”举行 多位诺贝尔奖得主齐聚

Core Insights - The second "Hong Kong World Youth Science Conference" and the 2025 "Hong Kong Innovation and Technology Forum" were held in Hong Kong, featuring Nobel laureates and academicians from around the world, including the notable couple Edward and May-Britt Moser, who won the Nobel Prize in Physiology or Medicine in 2014 for their discovery of grid cells in the brain [1] Group 1: Discovery of Grid Cells - The Mosers discovered grid cells, which are crucial for the brain's spatial navigation system, functioning similarly to a GPS [2][3] - Grid cells create a geometric pattern in the brain, forming a grid-like structure that helps in spatial awareness and navigation [2][3] Group 2: Implications for Brain Science - The discovery of grid cells is significant as it reveals that the brain has an internal map that is not solely reliant on sensory input but is generated internally [3][4] - This internal navigation system is universal across humans and animals, but its effectiveness depends on how individuals anchor this map to stable external landmarks [6] Group 3: Alzheimer's Disease Research - The research on grid cells has opened new avenues for understanding neurodegenerative diseases, particularly Alzheimer's disease, which is characterized by early degeneration in the entorhinal cortex where grid cells are located [7][9] - The Mosers emphasize the need to focus on specific brain regions like the entorhinal cortex to understand the mechanisms behind Alzheimer's disease and develop potential treatments [10] Group 4: Cultural and Educational Exchange - The Mosers have engaged in significant collaborations with Chinese researchers, highlighting the importance of integrating Eastern and Western medical knowledge [12][13] - Their experiences in China have led to fruitful academic exchanges, including the development of innovative microscopy technology by a talented student from Peking University [14][15] Group 5: Gender Equality in Science - May-Britt Moser discusses the challenges of gender bias in science, advocating for a focus on individual capabilities rather than gender [17][18]
