Public Lectures to Broaden Knowledge during the Pandemic

Prepare to be amazed by what kombucha can become. CUHK researchers have discovered that this beloved beverage holds the key to eco-friendly food packaging. It can be used to make a bio-based material that stretches like plastic but decomposes naturally, promising to revolutionise packaging. Best of all, it’s harmless and can even be eaten. Goodbye plastic pollution, thanks to the extraordinary potential of kombucha.

Facial recognition and public Wi-Fi are becoming more widespread in our daily lives. But have you ever considered that hackers are waiting around every corner to steal your credentials for profit? Fortunately, there are dedicated teams working tirelessly to combat these illegal activities. Two research teams from CUHK are hitting back at hack attacks as they examine vulnerabilities in facial recognition software and the configuration of virtual private networks and Wi-Fi networks.

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.

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.
