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 scholars recognised on the international stage

CUHK’s distinguished scholars have recently reaped several awards. Professor Li Cheuk-ting was honoured with the IEEE Information Theory Society Paper Award 2023; Professor Qin Ling and Professor Yu Jun were elected as Foreign Members of the Academia Europaea; and Distinguished Visiting Professor-at-Large Yau Shing-tung was awarded the Shaw Prize 2023 in Mathematical Sciences. Additionally, CUHK broke into the top 100 in THE Impact Rankings 2023 for the first time, making a significant milestone on its academic journey.

The cancer killer

Painful, debilitating and potentially dangerous: treating cancer metastases in the lungs through conventional methods is fraught with challenges. A new treatment, however, promises to revolutionise the process by using a remote, robotically controlled system to deliver a catheter into delicate areas of the lungs, where it can destroy the cancer cells precisely and effectively using microwave energy. Entirely non-invasive and in most cases pain-free, the system has delivered impressive results in early trials, successfully treating several patients with multiple lung metastases.

Beating back blindness

In today’s digital age, children spend most of the time glued to their devices, so the risk of them developing myopia is skyrocketing. Once the condition has kicked in, there’s no way of reversing it – and it can lead to all sorts of more serious eye problems. A new CUHK study demonstrates that giving children eyedrops featuring low concentrations of common anti-myopia medication atropine can prevent the condition from developing in the first place.

Guts and glory

Maybe you are one of the victims of a debilitating gastrointestinal disease, like gastric acid reflux or pathogen H pylori. When you are suffering from those diseases, you might wonder how bacteria which causes peptic ulcers can survive the acidic environment in your stomach? Besides risky invasive surgeries treating gastric acid reflux, is there an easier way getting rid of heartburn? You may be inspired by two recent CUHK breakthroughs.

Taking a bite out of shrimp allergy

Shrimp is one of the most common food allergies in the world, and severe allergic reactions can be life-threatening. But there’s some good news: researchers from CUHK have successfully identified 11 allergens in shrimp, which could help diagnose allergies more accurately. It means that in the future, when someone suspects they’re allergic to shrimp, a component-based specific IgE antibody test could be able to help them.

Fighting allergies: CUHK unravels the genome profile of the American cockroach

If you were to ask people which pest they hate the most, many would answer “cockroaches”, not only because of their unpleasant appearance but also because they can trigger allergic reactions such as asthma. Fortunately, a CUHK’s Faculty of Medicine team is producing the world’s most comprehensive genome profile of the American cockroach, aiding future diagnosis of cockroach allergy.

Retinal images can help early detection of Alzheimer’s disease

We all love to take photos, whether it’s to capture a special moment or to immortalise some beautiful scenery. Taking photos can also have far more serious purposes, though: for example, photos of your eyes can be used to detect Alzheimer’s disease. CUHK’s Faculty of Medicine has developed the world’s first AI model that can detect the disease solely through so-called fundus photographs: images of the retina.


Mites evolution discovery promises intervention in dangerous allergies

The bed you lie in, the food you eat - mites are everywhere. For people with mite allergy, they are devils causing itchy skins, shortness of breath, or even triggering severe diseases. Fortunately, a CUHK team has observed the unusual phenomenon on the evolution of astigmatic mites, laying the genomic groundwork for diagnosing and intervening in some dangerous human mite allergies.

Racing against mutation: COVID-19 vaccine effectiveness predicted in real time

The COVID-19 virus is mutating rapidly. As subvariants like BA.4 and BA.5 emerge, we must act fast to curb the pandemic. Vaccination is the most effective way to control epidemic, but the protection it offers declines as the virus evolves. Predicting vaccine effectiveness in a short time frame is key to winning this battle. CUHK researchers have developed a bioinformatics platform that can provide a snapshot of vaccine effectiveness in real time, instead of it taking months.

Non-invasive imaging detects early-stage “silent killer” liver fibrosis

An unhealthy diet, lack of exercise and staying up late are common habits that can damage our livers. The liver is known as a silent organ: symptoms of liver failure do not typically show up until they develop into severe fibrosis, cirrhosis or even cancer. A team from CUHK is developing a non-invasive imaging method to detect biochemical symptoms associated with early-stage liver fibrosis, increasing the chances of successful treatment.

The Discovery of an Oncogene in Gastric Cancer Overturns Previous Reports

Cancer is a group of diseases that we are taking kinds of strategies to overcome at the moment. Our bodies are made up of countless cells, and cancer cells are the result of mutations of normal ones. Although its causes are not yet fully understood, studying the mechanisms of cancer cell proliferation allows us to understand cancer better and create new treatments. A team from CU Medicine has just identified a novel oncogene in gastric cancer, giving rise to the development of a new anti-cancer therapy.

COVID mRNA Booster Key to Protecting High-risk Populations

CU Medicine has conducted what is, to date, the largest sample (about 100 million subjects), worldwide study of 24 combinations of COVID-19 vaccines covering seven vaccine types. It shows that, whilst three doses of an mRNA vaccine greatly reduce COVID-19 infection risks in immunocompromised and elderly patients compared to only two doses of vaccines of any kind, an mRNA booster to two doses of any other vaccine protects them against non-severe COVID-19 infections. Very importantly, say the findings, a third dose of mRNA vaccine is necessary to protect against Omicron infection.

CUHK Scholars and Students Given Awards for Innovative Research

Professor Mei-Po KWAN from CUHK’s Department of Geography and Resource Management has been awarded the James R. Anderson Medal of Honor in Applied Geography, the highest honour in the field, for her multidisciplinary contributions to applied geography; while Professor YU Jun from the Faculty of Medicine has been awarded the Guanghua Engineering Science and Technology Award by the Chinese Academy of Engineering in recognition of her distinguished achievements in gastrointestinal cancer studies.

Gut Feeling about Handling Long COVID

The Microbiota I-Centre of CUHK has identified distinct gut microbiome profiles that can characterise “long COVID”. This is the world’s first study to demonstrate gut microbiota as a key determinant of long COVID. These distinct gut microbial signatures can be used as a diagnostic tool and to guide therapy.

New Light on Causes of Severe Inflammation in COVID Patients’ Blood Vessels

A new pathway has been found whereby SARS-CoV-2 infects the endothelium cells – the innermost layer of the blood vessels, causing hyper inflammation, blood clotting and thrombosis in severe COVID-19 patients. In a collaborative research, a CU Medicine team has discovered that the virus induces inflammation by activating a unique cell surface receptor called (TLR) 4, without entering the host cell.

Gold Nanoparticle in Long Awaited Strike for Psoriasis Sufferers

Gold is anti-inflammatory and has applications in the fields of jewelry, aviation, chemistry, and electronic circuit boards. Now researchers from CUHK Engineering have struck gold for psoriasis sufferers by developing a self-therapeutic gold nanoparticle that does not contain steroids and vitamin D analogs but has a similar effect, as proven in mice models. It was demonstrated that the gold nanoparticle could enter skin epidermal cells without causing hair loss and skin wrinkling.

Strengthened Response to COVID Vaccines Could Come from the Gut

Sinovac and BioNTech work more effectively in people who have an abundance amount of a particular bacterium called Bifidobacterium adolescentis in their gut. In most of us, this reduces with age, modern diet, stress, and the use of antibiotics, and a joint CUHK-HKU study has found that those who lack it have a lower antibody response to the vaccines. This implies that modulating the gut has potential to power up the impact of COVID vaccines.

A Predictive Platform to Combat Infertility

Anticipating a newborn brings joy to parents but delays in marriages and childbirth planning make it harder to conceive successfully. Selecting a high developmental potential embryo is still the key to pregnancy even though assisted reproductive technology like conventional IVF has been advancing with time. CUHK researchers have recently developed a new predictive platform which helps doctor to select an appropriate embryo and devise transfer schemes to increase the rate of success.

No More Probes! World-First Sensitive Faecal Test for Colon Cancer and Polyps Detection

A low sensitivity faecal test is used to screen for colorectal cancer. Its cause, polyps can only be detected by a probing colonoscopy. Now a CUHK Medicine team has devised a first ever, highly sensitive, non-invasive “bacterial gene markers” test on faeces. It is 94% sensitive to the cancer, and over 90% sensitive to recurring polyps - which the present test can’t detect at all.


Once Fighting Hepatitis, Now Re-enlisted to Confront COVID-19.

Simeprevir was a successful drug retired from the fight against the hepatitis C virus when new drugs and advanced treatment came into the field in recent years. An international research team led by CUHK and HKU seeking an effective drug molecule against COVID-19 has re-enlisted simeprevir as a potent treatment to suppress the replication of SARS-CoV-2.

Microrobotic Doctors Roam Deep into Your Body for Treatments

A sci-fi adventure film from the 1960s, Fantastic Voyage, features a group of doctors shrinking into microscopic size and venturing into a patient’s brain to repair damages. A CUHK research team has recently brought this surreal fantasy to life by developing biohybrid soft microrobots, which navigates in tiny lumens for health inspections and medical treatments.

Vaccine Effectiveness against Seasonal Flu Predictable by Computer

Innovative algorithms developed by a CUHK team, using bioinformatics analysis of virus genome, can estimate vaccine effectiveness (VE) by quantifying the relationship between the genetic mismatch between flu vaccines and current virus strains. This real-time prediction method of VE early in flu season gives the government a heads-up in selecting effective vaccines and organising resources before mass vaccination.
