Century-Old "Spectral Ghost" Paradox Resolved

In a landmark achievement, a research team led by Prof. Dong Li, Chair Professor in the Department of Mathematics at HKU, has resolved a long-standing mathematical paradox known as the spectral ghost in nonlinear dispersive equations. This breakthrough, published in the prestigious, peer-reviewed academic journal that publishes original research papers across all fields of mathematics, Inventiones mathematicae, carries profound implications for both fundamental science and societal advancement.

Unlocking Quantum Potential: How AI is Contributing to the Future of Quantum Technologies and Society

A groundbreaking research project led by Prof. Giulio Chiribella, Associate Director (Research & Graduate Studies) of HKU’s School of Computing and Data Science, is transforming how we understand and interact with the quantum realm. The key idea of this project is to “See the Quantum World Through the Eyes of AI," leveraging artificial intelligence (AI) to characterise and control large-scale quantum systems—an essential step toward realising practical quantum technologies, such as quantum computers and quantum communication networks.

Advancing the I&T Ecosystem: HKU TEC Launches Gobi-HKU Fund I and Venture Mentoring Service

HKU’s Techno-Entrepreneurship Core (TEC) has taken significant steps to enhance regional development and technological innovation through the launch of two major groundbreaking initiatives.

HKU Receives 46 Awards at the 51st International Exhibition of Inventions of Geneva

The Innovation Behind Pearl Powder Face Masks

The Pearl Power Research Institute (PPRI) is pioneering skincare innovation with its new pearl powder face mask, built on a patented antioxidant technology. This face mask stands out because it utilises a high concentration of natural pearl powder from accredited local fish farms in Hong Kong, ensuring both safety and traceability. Unlike many competitors that add minimal amounts of generic pearl powder, this mask employs a proprietary dispersion method that enhances absorption, delivering more active materials effectively to the skin.

Revolutionising Computing: Insights from Prof. Ngai Wong

In an era where artificial intelligence and computing are evolving rapidly, Prof. Ngai Wong from HKU’s Department of Electrical and Computer Engineering and Director of the Emerging Microelectronics and Ubiquitous Systems (EMUS) Lab is at the forefront of research that intertwines biological intelligence and advanced hardware. His work centres on the concept of "dual-system collaboration," in which two distinct systems enhance each other's performance to deliver groundbreaking results.

Advancements in Organoid Technology: Implications for Public Health

Recent advancements at HKUMed have pioneered the development of an innovative respiratory organoid culture system and organoid-based platform for evaluating the efficacy of SARS-CoV-2 neutralising antibodies. These revolutionary respiratory organoid models mimic human respiratory tissues, enabling researchers to assess the effectiveness of antibodies and vaccines in realistic conditions. As respiratory viruses continue to pose significant public health challenges, the implications of this technology are profound.
