[The Bigger Picture](https://bulletin.hku.hk/research/the-bigger-picture/ "This link will pop up in a new window")
Using an innovative combination of the Sentinel-2 satellite mission and its dynamic time-series capabilities, along with phenological observations, biological scientists have made a promising advancement in mapping plant functional traits from space.
[Invisible Engineers](https://bulletin.hku.hk/research/invisible-engineers/ "This link will pop up in a new window")
New findings highlight the critical role of invertebrates in breaking down forest litter and thereby helping sustain carbon and nutrient cycling.
[Maternal Instinct](https://bulletin.hku.hk/research/maternal-instinct/ "This link will pop up in a new window")
Researchers from HKUMed have found that extending Hong Kong’s statutory paid maternity leave led to a significant improvement in maternal mental health. The findings have significant implications at a time when birth rates worldwide are falling and labour force shortages are a significant problem.
[Hep to a Cure](https://bulletin.hku.hk/research/hep-to-a-cure/ "This link will pop up in a new window")
World-leading hepatitis researcher, Professor Yuen Man-fung, has made serious inroads towards a cure for some hepatitis B patients. He is also working to get more people tested so they can seek treatment for this silent but harmful virus.
[More than a Feeling](https://bulletin.hku.hk/cover-story-theme/more-than-a-feeling/ "This link will pop up in a new window")
Bioethicist Dr Zohar Lederman has been exploring the philosophical implications of the individual and social harm caused by loneliness, and practical solutions.
[A Slippery Slope to Depression](https://bulletin.hku.hk/cover-story-theme/a-slippery-slope-to-depression/ "This link will pop up in a new window")
Professor Tatia Mei-chun Lee and her colleagues have been investigating brain activity to see how loneliness can tip people into depression and what might be done to mitigate the effects.
[Relief for the Lonesome](https://bulletin.hku.hk/cover-story-theme/relief-for-the-lonesome/ "This link will pop up in a new window")
HKU researchers have been investigating interventions to help alleviate loneliness among Hong Kong’s elderly.
[‘Facial Recognition’ for Cells](https://bulletin.hku.hk/cover-story-theme/facial-recognition-for-cells/ "This link will pop up in a new window")
Computer vision has an important role to play in medical diagnostics. Building on a decade of work in the field, Professor Kevin Tsia recently deployed an AI-driven, ultra-fast imaging tool to speed up cancer diagnosis and, in a separate project, applied AI to decode the development of zebrafish from images and other data.
[Smart Eyes on the Street](https://bulletin.hku.hk/cover-story-theme/smart-eyes-on-the-street/ "This link will pop up in a new window")
Streets, sidewalks and roads which constitute more than a quarter of the built-up land in most cities, should be designed for people, but urban planning has typically not incorporated human perspectives. With the aid of urban big imagery data and AI, Professor Qiu Waishan is helping to correct this.
[Computers Take the Wheel](https://bulletin.hku.hk/cover-story-theme/computers-take-the-wheel/ "This link will pop up in a new window")
The technology behind embodied AI and autonomous cars has made huge strides in recent times, helped in part by a system devised by HKU Professor Li Hongyang and his collaborators.
[Modelling Human Vision](https://bulletin.hku.hk/cover-story-theme/modelling-human-vision/ "This link will pop up in a new window")
Professor Andrew Luo’s work is deepening understanding about how the human brain processes and understands images, which has implications for the development of machine vision.
[Perfecting the Image](https://bulletin.hku.hk/cover-story-theme/perfecting-the-image/ "This link will pop up in a new window")
