Biofilms, which can occur in various places in the human body, can cause a range of infections. Made of microbes encased in a matrix that makes them resistant to external threats, they are notoriously hard to shift, especially when they accumulate on the surface of medical implants. New devices called “magnetic hydrogel micromachines”, developed by a CUHK team, are formidable weapons to resist and overcome the biofilm menace. It can be controlled by magnets, to precisely target the biofilm for removal.
Wearable artificial muscles offer the hope of recovery for people with devastating injuries and medical conditions. With ExoMuscle, Professor Raymond Tong Kai-yu from CUHK has come up with the most effective artificial muscle yet developed: twice as strong as human muscles, it could potentially be used to create a wearable exoskeleton, like something worn by super villain Doctor Octopus. ExoMuscle interprets signals from the muscles and brain through a unique interface that connects them with the bionic muscle.
Can you imagine how hot you would feel when a heatwave comes if you lived in a tin-sheet house? It would be like living in a steam oven. Heatwaves are roasting the world, smashing records with unrelenting severity. A CUHK research team has developed a high-performance radiative cooling paint based on recycled glass, a forgotten resource in our communities. It can potentially provide buildings with supplemental cooling without consuming energy.
Professor Katalin Karikó’s story is a shining example of how the power of persistence can lead to discoveries that change the world. In the face of countless obstacles, she tenaciously pursued her vision of utilising mRNA for therapy for decades. Alongside Professor Drew Weissman, their research paved the way for the development of life-saving Covid vaccines. She embodies not only relentless pursuit of scientific knowledge, but also the hope to ignite passion and inspire young minds about the wonders of science.
CUHK’s new centres are set to usher in an era of thrilling academic collaboration and scientific breakthroughs. The internationally accredited CU-Med Biobank promises revolutionary drug research, while the S.H. Ho Research Centre for Infectious Diseases unites researchers to fight contagious diseases. The CUHK Beijing and Shanghai Centres create a vibrant corridor, bridging mainland China and Hong Kong and forging new knowledge, innovation and industry partnerships.
CUHK awarded the degree of Doctor of Science, honoris causa to biochemist Professor Katalin Karikó, the scientist behind mRNA vaccines. Professor Karikó expressed optimism in Hong Kong that mRNA technology can be used to treat various conditions beyond Covid-19.
Professor Tam Lai-shan from the Department of Medicine and Therapeutics at CUHK has suggested in a study that daily doses of low-dose steroids (below 5mg) may not increase the risk of cardiovascular events in patients with rheumatoid arthritis.
A study by CUHK and the Hong Kong University of Science and Technology has found that COVID-19 can cause pregnancy complications by altering gene regulation within the placenta, leading to abnormal blood vessel formation and foetal growth restriction.
Asian universities face challenges such as demographic changes and geopolitical complexities. Professor Rocky S. Tuan, CUHK Vice-Chancellor and President, argues that collaboration and partnership among universities can address these challenges and propel progress.
A research team from the Department of Mechanical and Automation Engineering at CUHK has developed magnetic hydrogel micromachines, which are expected to be of great value in medical applications.
