Reef relief: building a better future for coral

Brightly coloured, fractally shaped and home to a plethora of sea life: everyone loves coral. However, from the effects of climate change, pollution, overfishing to an increasingly populated planet – corals are under threat. CUHK scholar Dr Apple Chui Pui-yi is collaborating with the WWF to fight back on their behalf, with a coral rescue team that’s helping coral to flourish.

Screening for cervical cancer on your own

Cervical cancer kills hundreds of thousands of women around the world every year, but fear of embarrassment or inconvenience means some women refuse regular pap tests. A CUHK Biochemistry alumna is trying to revolutionise cervical cancer screen with a non-invasive technology that allows women to simply identify the disease in menstrual blood at home, using a sanitary napkin which is included in the self-test kit.

Planting a seed: the botanical database of the future

Around the world, there are over 390,000 plant species known to science. That makes it challenging for scientists to study them. A systematised database is important to provide an insightful reference for plant identification, ecological surveys and conservation. A research team from CUHK has developed a first-of-its-kind 3D and high-definition open database of authenticated fruits and seeds voucher specimens in herbarium archive, allowing researchers, teachers and students to explore, rotate and magnify lifelike 3D models of plant species – just like holding the real thing in their hands. It is a template for botanists and herbaria worldwide to establish their own 3D databases and help revolutionise our approach to studying a key part of the natural world.

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.

Bringing New Light from Dinosaurs to Ancient Man

A CUHK palaeobiologist co-developed laser stimulated fluorescence imaging while pursuing how running dinosaurs evolved into flying birds. The technique revealed unseen fossilised tissues so well, it inspired a crossover to a completely different discipline, archaeology.

Novel Molecular Mechanism Enhancing Drought Resistance of Plants

As the world warms, it poses a serious threat to the production yield of crops worldwide caused by widespread extreme weather such as drought and hot waves. A CUHK life sciences team has recently discovered a novel molecular mechanism underlying plants response to stress which provides a new understanding of how to improve the drought resistance of plants in bioengineering.

The Dawn of the Deadly Huntington’s Disease

Professional dancers move with intention through rehearsed and controlled movements but there is a deadly genetic disorder, Huntington’s Disease, which forces the body into an uncontrolled unlovely dance from unpredictable muscle movements. Scientist from CUHK has worked a wonder in discovering a novel molecule compound potentially effective in treating the disease, by uncovering the culprit for the neuronal DNA damage.

Mangroves May be Threatened by Low Functional Diversity of Invertebrates

Mangrove forests need a healthy community of invertebrates to sustain their trees. But a study of mangroves worldwide suggests most suffer from “low functional diversity”. If one invertebrate species is lost, its functional role may not be filled by another species. The good news? Hong Kong’s small mangroves remain healthily diverse. The message? Understanding invertebrates’ diversity is crucial for the assessment and management of mangroves.

New Treatment Puts a Brake on Parkinson’s

It began with a PhD student in a CUHK research team making a surprising discovery. A protein commonly found in humans can suppress the toxic protein in the brain that leads to loss of cognitive and motor functions. From this the team has developed a peptide inhibitor that can slow down deterioration in people with Parkinson’s disease and dementia.

Uncovering a Swarming Mystery of the Ocean

Of the jellyfish- not actually a fish - little is known about its evolution, reproduction, or feeding habits. For years CUHK researchers have dived deep into jellyfish genomes and decoded for the first time the high-quality genomes of two jellyfish commonly found in Asian waters, shedding new light on these translucent mysteries of the seas.
