Revitalising what was once lost in local paddy

Just as with the artifacts and heritage of the lost and legendary Incan city of Machu Picchu, many places in the world lost facets of their cultures which are worth reviving and restoring. As other historians and anthropologists have done, a fervent CUHK scientist, works hard and reinvigorates what was always with us, to successfully track down and replant lost local rice with a unique genome, returning it to its place of value in the community.

The heat is on – welcome to the furnace

A summer of heatwaves has wreaked havoc on human health, food security and natural ecosystems all over the world this year. With climate change on the march, Hong Kong, as a tiny dot on the map, can’t escape its effects. CUHK experts on climate change, earth and environmental sciences, and architecture discuss what the consequences could be, and what can we do to alleviate them.

Robots in disguise: the science of folding

What can you do with tape? Seal your package or to bind an injury? The uses of tape go much further than that in the hands of a CUHK Engineering professor who has devoted himself to medical robotics. By simply tattooing magnetised patterns onto tapes and using a magnetic field, a highly versatile “origami” soft robot is miraculously brought into being that can morph into a variety of 3D shapes - and behold, they have a future in medical and industrial applications.

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.

Setting sail for a sustainable future

The world is facing a confluence of crises in food and nutrition, health, education, the environment, and peace and security that threaten the very survival of humanity. To put the world on track to sustainability will require concerted action on a global scale. The education system plays an important role in raising awareness of sustainable development goals and teaching the skills needed for a sustainable world. CUHK has joined the multi-institutional Future17 programme, taking students on a journey to unleash their creativity and develop solutions that tackle SDG-related challenges.

“Bee” Microrobots can Swarm Autonomously Inside You

In a flower garden, we have army of honeybees that swarm to defend enemies; in a tortuous human lumen, we have army of microrobots that swarm to carry drugs that attack maladies. CUHK engineering professors have devised an avant-garde AI system that lets these microrobots navigate like bees and change shape inside complex environments like human bodies……

New Electrolyte Enables a Stable Power Supply to Win the “Cold War”

Life in an extremely cold region without electricity for heating and lighting can be a miserable experience, especially as existing battery technologies cannot retain a reliable power supply in such cold weather. When winter storms sweep across cities, the power crisis they cause can leave millions of people without electricity. CUHK researchers are trying to fix that with a new technology that promises to bring stability to electrical storage, even at very low temperatures……

CUHK Researchers Contribute First Black Hole Image from Milky Way’s Heart

After five years of effort, the first image of Sagittarius A*, 26,000 light-years away at the centre of the Milky Way, produced by the Event Horizon Telescope, has proved it to be a supermassive black hole. A CUHK scholar and a student from the Department of Physics are Hong Kong’s only participants in the team and have studied the simulation of gas movement and the mechanism of infalling gas around the black hole using supercomputers to help unravel the mystery of black holes……

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……
