HKU Research Team to Develop “Short-Wavelength Infrared Spectrometer” for China’s Tianwen-3 Mission Advancing the Search for Signs of Life on Mars

A research team from the Department of Earth and Planetary Sciences will participate in China’s planetary exploration mission, Tianwen-3. According to the selection results recently released by the China National Space Administration, the “Short-Wavelength Infrared Spectrometer”, led and developed by HKU, has been officially selected as a payload for deployment on the service module of the Tianwen3 mission. The instrument will play a critical role in forecasting dust storms during landing manoeuvres, searching for biosignatures, detecting hydrous minerals, and surveying Martian resources. In addition, the orbiter will carry three collaborative payloads, including the COSPAR-led Martian PEX spectrometer, on which the HKU Laboratory for Space Research participates alongside Shenzhen University. Tianwen-3 mission is China’s first Mars Sample Return mission. Scheduled for launch in 2028, with sample return planned for 2031, the mission aims to address fundamental scientific questions, including the uniqueness of life on Earth and the universality of biochemical mechanisms in the universe. Professor Xiang ZHANG, President and Vice-Chancellor of HKU, commented, “HKU is honoured to participate in the Tianwen-3 planetary exploration mission. The selection of our research project as a mission payload reflects the University’s deep-seated expertise in planetary science and deep-space exploration, while marking a significant contribution to the nation’s strategic advancement as a leading space power. We remain committed to deepening our frontier research to further expand the boundaries of human knowledge.” The project is led by Professor Yiliang LI of the Department of Earth and Planetary Sciences at HKU, with major collaborating institutions including Zhejiang University and the Chinese Academy of Sciences’ Changchun Institute of Optics, Fine Mechanics, and Physics. The instrument will be used for key investigations, including forecasting dust storms during the landing maneuver, searching for biosignatures, detecting hydrous minerals, and surveying resources on Mars. The orbital spectrometer will undertake three primary tasks: 1. To monitor the potential emergence and development of dust storms, thereby guiding the safe landing of the lander at sites of highest scientific value. 2. To provide detailed, high-spatial-resolution mineralogical mapping of candidate landing sites from orbit, supporting final-stage landing site selection for the Tianwen-3 mission. 3. Following completion of the sample return phase, the instrument will remain in orbit for at least five years to conduct sustained observations of Mars’s low-latitude regions. Professor Li stated: “This mission marks a significant contribution from Hong Kong’s scientific community to the nation’s deep space exploration programme. Using hyperspectral imaging technology, we will directly search for biosignatures and hydrous minerals on Mars, which is fundamentally important for understanding the distribution of life in the universe.” Professor Li has served as a core member of both the Landing Site Selection Team and the Mission Science Team of the Tianwen-3 mission. The selection of this payload demonstrates HKU’s international competitiveness in Earth and planetary sciences while fostering interdisciplinary synergy across science and engineering in Hong Kong. Professor Li further noted that the project aligns with two concurrent developments: “First, the continued expansion of HKU’s research capabilities in Earth and planetary sciences, particularly in cosmochemistry and astrobiology focusing on solar system bodies such as asteroids, Mars and Jupiter; and second, the Hong Kong SAR Government’s strategic initiative to cultivate a local aerospace industry, by leveraging the region’s geographical advantages.” Professor Yiliang LI of HKU Earth and Planetary Sciences.

Exploring Italy’s Scientific and Cultural Heritage: A Journey from Trieste to Venice

Three PhD students, Min LONG, Menghan SONG, and Ting-Tung WANG, from the group of Professor Zi Yang MENG in the Department of Physics, embarked on a scientific journey at the Abdus Salam International Centre for Theoretical Physics (ICTP) in Trieste, Italy, last December. Below, they share their experiences of exchanging knowledge and exploring the rich history and culture of Trieste and Venice. Trieste: A City of Borders and History Trieste is a port city that once served as the main sea gate of the Austro-Hungarian Empire. Today, the empire is gone, and the city is Italian, but its unique identity persists. The architecture reflects its imperial past, with grand, sombre buildings from the Habsburg era facing the waterfront. The piazzas are wide and open to the sea breeze, and historic cafés invite you to enjoy coffee amid a blend of influences – more reminiscent of Vienna than Rome. The light is Adriatic, but the soul is mixed, reflecting a city of borders and changed maps. Sculpture in Piazza Unità d'Italia In December 2025, we visited the Abdus Salam International Centre for Theoretical Physics (ICTP). The Centre is a cluster of functional buildings on the outskirts of Trieste. Founded by the late Nobel Laureate Abdus Salam and Italian physicist Paolo Budinich, it is a hub for scientists from all over the world, especially those from developing countries. It is a tranquil place with plain corridors and a slow pace. Here, we participated in a two-week Advanced School and Conference on Quantum Matter. The event intertwined pedagogical lectures from the school and conference-style talks on Quantum Spin Liquids. At ICTP, we had enriching conversations with research scientists Marcello Dalmonte, Yin Ran, and Cenke Xu. Topics ranged from cutting-edge hybrid Monte Carlo simulations of fractional quantum Hall states—platforms for quantum computation—to the intricate techniques of entanglement microscopy that reveal the deep organising principles governing many-particle systems. A highlight was the exploration of the Chiral graviton—a phenomenon akin to ripples in the emergent internal geometry of the electronic universe—and its realisation in the fractional Chern insulator. These fruitful exchanges have already led to our recent preprint, Chiral Graviton Modes in Fermionic Fractional Chern Insulator, and we anticipate further collaborations, including a forthcoming visit to HKU by an Italian scholar. Many distinguished Chinese physicists, such as Xi Dai and Lu Yu, have worked at ICTP. They did important work and helped facilitate knowledge exchange with their home institutions. ICTP has served as a bridge, facilitating knowledge exchange through sustained, dedicated work. In the cafeteria, a dozen languages mingle, unified by the language of physics. It is a truly inspiring place. The Grand Canal The ICTP campus From Trieste to Venice: A Coastal Journey From Trieste, we took a two-hour train ride along the coast to Venice. Venice is unlike any other city. Stepping out of the station, you are greeted by the water of the Grand Canal. There are no cars, only boats. The city is built on millions of wooden pilings driven into the mud of the Venetian Lagoon. Once a powerful maritime republic, its wealth is evident in landmarks like the Doge’s Palace and the Basilica, with gold accents and ornate ceilings. Yet, the true essence of Venice lies in its small details. While in Venice, we took a boat out to Murano, the island famed for glassmaking. Watching a master shape molten glass into a delicate horse in just minutes revealed the skill and artistry behind this ancient craft. Back in the city, the streets are canals. The sidewalks are narrow. We crossed small bridges and passed shops displaying traditional Venetian Carnival masks—some simple white, others gilded with long beaks. These masks were once worn during festivals to conceal identity, allowing people to step outside their usual roles. Today, they are mostly made for tourists, but they still carry a sense of the city’s old mystery. From left: Menghan Song, Ting-Tung Wang and Min Long As the light faded, the crowds departed on their boats, and the city quietened. We could hear the water lapping against the ancient stones. We found a small place to eat—simple fare of fish, pasta, and house wine. The next day, on the return train along the coast, we reflected on the two cities. Trieste, solid and serious on its land, is focused on fundamental questions about the universe. Venice, floating on its borrowed time, stands as a beautiful relic of the past. Both are real, and both tell a true story. That, in itself, is enough.

HKU Astrophysicists Find Saturn’s Magnetic Bubble Differ from Earth-Based Models, Appearing to be Less Symmetrical and Off-Centre

Latest research led by Professor Zhonghua YAO of the Department of Earth and Planetary Sciences (DEPS) at The University of Hong Kong (HKU) has found that auroras on Saturn behave markedly differently from those on Earth, appearing uneven and shifted to one side rather than forming the familiar symmetrical rings around the poles. Analysing archival data from NASA’s Cassini mission, the team shows that Saturn’s rapid rotation fundamentally reshapes its magnetic environment, driving this off-centre magnetic bubble pattern. A Shield with a Systematic Shift Like Earth, Saturn is surrounded by a magnetosphere, a magnetic “shield” that protects it from the solar wind. However, near the poles, funnel-shaped openings called “cusps” allow charged particles to leak into the atmosphere along magnetic field lines, producing auroras. On Earth, these entry regions, similar to a magnetic bubble, are usually centred around noon—the part of the planet facing the Sun—so the magnetic bubble tends to form fairly symmetrical rings around the poles. At Saturn, the dynamics change dramatically. These regions are shifted towards the afternoon side, most commonly between about 1 pm and 3 pm, and sometimes extending towards evening. As a result, the auroras are not centred, but displaced to one side, appearing uneven rather than forming a balanced ring. This difference is linked to Saturn’s rapid rotation. A full rotation takes only about 10 hours, and this fast spin reshapes the planet’s magnetic field, pushing the particle entry regions away from the Sun-facing direction. The findings suggest that, for giant planets like Saturn, rotation and charged particles released by its moons may play a larger role than the solar wind in shaping the magnetic environment. By identifying where charged particles enter a planet’s magnetic field, scientists can better understand how energy is transferred into its atmosphere. This helps improve models of planetary magnetic fields and space weather, and provides insight into how effectively different planets can protect their atmospheres. “This discovery of an ‘afternoon-skewed cusp’ confirms that giant planets operate under a different magnetospheric environment than Earth,” said Professor Yao. “It fundamentally alters our models of how high-energy particles gain energy and move faster across our solar system”. The research, published in Nature Communications, draws on data collected by the Cassini spacecraft, which orbited Saturn from 2004 to 2017. By analysing data up to 2010, the team identified 67 instances of particle entry into Saturn’s magnetic field, allowing them to map these regions for the first time. The study’s first author is Dr Yan Xu, a former postdoctoral fellow of Professor Zhonghua Yao at HKU, now affiliated with the Southern University of Science and Technology in Shenzhen.

Supported by the Environment and Conservation Fund (ECF), the programme immerses local secondary school students in marine science through hands-on training, empowering them as the next generation of ocean stewards. The programme was inaugurated at an opening ceremony on 30 January at the Rayson Huang Theatre at HKU, attended by Professor Jay SIEGEL, HKU Vice-President and Pro-Vice-Chancellor (Teaching and Learning); Professor David BAKER, Interim Director of SWIMS; Dr Eric Kam-chung CHENG, Chairman of the Environment and Conservation Fund Committee; and Dr Jim CHU, Assistant Director (Fisheries and Marine Conservation) of the Agriculture, Fisheries and Conservation Department (AFCD). More than 100 students and teachers from 25 secondary schools in Hong Kong attended the ceremony. Student Lolan CHIU identifying marine species she found on an ARMS under a microscope. Hands-On Learning in Marine Science and Conservation Each participating school nominates five student ambassadors to take part in a four-day immersive training programme at SWIMS’ Cape D’Aguilar research facility, located adjacent to the Cape D’Aguilar Marine Reserve. The programme blends lectures, laboratory sessions, and field visits to key sites such as Hoi Ha Wan Marine Park, Telegraph Bay, and Tai Tam, covering diverse habitats including coral communities, rocky shores, and mangroves. Students gain firsthand experience with advanced research techniques used by marine scientists, including drone mapping of restored mangroves and environmental DNA (eDNA) analysis for species detection. The programme also focuses on building leadership and advocacy skills, enabling participants to share their knowledge within their schools and wider communities. Ms Janis MOK, Outreach and Strategic Partnerships Manager at SWIMS, explained the mission, “This programme unites Hong Kong’s schools, cboth local and international. We hope to achieve a cascading and multiplying effect, reaching beyond the students we teach. Already, 175 students from 39 schools have signed up, exceeding our expectations.” Dr Jim CHU, AFCD Assistant Director (Fisheries and Marine Conservation) emphasised the programme’s broader goal: protecting Hong Kong’s marine environment, “The most important message is to teach the general public to protect our oceans, how to enjoy nature while being its guardians, not just its guests.” Inaugural Workshop Engages Students in Biodiversity Discovery Dr Phil Thompson and an ARMS that he just retrieved from the sea. Participants in the Discovering Marine Biodiversity workshop at SWIMS The first workshop of the programme, Discovering Marine Biodiversity, took place on 28 February. Students explored Hong Kong’s rich marine ecosystems and the importance of conservation, followed by interactive activities such as identifying marine organisms collected using an Autonomous Reef Monitoring Structure (ARMS). “The workshop was fantastic! The kids were super engaged, jumping right in, collaborating,” said Josh BLUE, Head of Education, Curriculum, Learning and Assessment Education at English Schools Foundation. He continued, “Hopefully, we will continue building on this message of sustainability, protecting marine ecosystems, and creating a better world.” SWIMS Outreach and Education Officer Dr Phil THOMSON agreed, “Everyone was very enthusiastic! The challenge is to identify the organisms they find on the ARMS, but this is the whole point of this exercise. The number of species, or biodiversity, matters for the health of the environment. That’s the important message from the course that the students will share with their peers.” One of the participating students, Lolan CHIU, a year 12 student at ESF Sha Tin College, said the programme gave her a glimpse into what being a real scientist means, “I want to become a marine biologist. I have already been to the Philippines to get my SCUBA diving license and Thailand to participate in CoralWatch. I was really surprised by how detail-oriented you have to be, looking at different species and carefully observing small details in their shapes and patterns! I cannot wait to share with my schoolmates what I have learned in this programme.” The programme represents a significant step in nurturing youth engagement in marine conservation and strengthening Hong Kong’s culture of environmental stewardship.

HKU Team Explores Ancient Pathogens in Antarctica

HKU researchers have returned from Antarctica after collecting sediment samples from penguin colonies to trace ancient pathogens and understand how environmental change shapes microbial ecosystems. The fieldwork brings together researchers from across HKU, including the School of Biological Sciences (SBS), and is led by the School of Public Health (SPH), with collaborators from the University of Nottingham. By analysing DNA preserved in layers of sediment rich in penguin guano, the team aims to reconstruct past microbial communities and identify potential pathogens associated with penguin populations. Collecting Clues from Antarctic Lake Sediments Fieldwork was carried out on King George Island and Ardley Island in Antarctica as part of the PathoPast project, led by Dr Alexander Williams (Postdoctoral Fellow, SPH), with contributions from Dr Martha Ledger (Postdoctoral Fellow, SBS) and Dr Roseanna Mayfield (Assistant Professor, the University of Nottingham). The team collected sediment cores from Antarctic lakes located near historic penguin colonies. These layered sediments act as natural archives, preserving biological material deposited over decades to centuries, including large quantities of penguin droppings, or “guano”. By analysing ancient nucleic acids preserved within the guano-rich sediments, the project aims to reconstruct past microbial communities and identify potential pathogenic organisms associated with penguin populations. Although Antarctica is often perceived as pristine and isolated, it is experiencing rapid environmental change. Shifts in temperature, wildlife distribution and human activity may influence microbial dynamics in ways that are not yet fully understood. “Sediment cores allow us to look back in time,” said Dr Williams. “By analysing the microbial traces preserved in lake sediments, we can reconstruct how they have fluctuated over time in response to environmental change. This helps us understand not only wildlife health in polar ecosystems, but also broader One Health dynamics, including how environmental shifts influence pathogen circulation across wildlife, ecosystems and potentially even human interfaces.” PathoPast field team in Antarctica (from left): Drs Martha Ledger, Alexander Williams and Roseanna Mayfield. Image credit: Martha Ledger. Fieldwork Under Extreme Conditions Fieldwork was conducted on Ardley Island and King George Island under challenging logistical and environmental conditions. The team carried specialised coring equipment and an inflatable dinghy, weighing a combined 70kg, across difficult terrain in cold, highly variable weather conditions, working within tight operational windows. “Antarctic fieldwork requires careful planning and resilience,” Dr Ledger added. “Weather conditions can change rapidly, and every sediment core extracted requires coordinated teamwork. But being able to recover these intact sediment records from such a remote environment is incredibly rewarding.” In addition to sediment cores, the team collected modern penguin guano samples to assess present-day microbial communities. These samples will be analysed at the HKU State Key Laboratory of Emerging Infectious Diseases and compared with the historical records preserved in the lake sediments. Antarctic research access is highly internationally competitive. The project benefited from transnational access to the Professor Julio Escudero Base, funded by the European Union’s Horizon Europe programme through the POLARIN project (Grant Agreement No. 101130949). At HKU, the project is conducted under the supervision of Professor Tommy Lam from SPH, with support from The Hong Kong Jockey Club Global Health Institute (HKJCGHI), which contributes to its conceptual design, laboratory work and data analysis.

HKU Study Uncovers Mineral “Sink” that Reduced Phosphorus in Early Oceans Potentially Delaying Earth’s Oxygen Rise

Scientists have long sought to explain a key mismatch in Earth’s early history: oxygen-producing photosynthesis evolved hundreds of millions of years before atmospheric oxygen began to rise during the Great Oxidation Event. This delay has been linked to limited phosphorus—a nutrient essential to life—but the specific processes controlling phosphorus availability in the iron-rich oceans of Archean Earth (approximately 3.2–2.5 billion years ago) remained unclear. A study led by the Department of Earth and Planetary Sciences at The University of Hong Kong (HKU) has identified a previously overlooked process that may explain this prolonged delay. The research was conducted in collaboration with the University of Science and Technology of China (USTC). The work was led by HKU’s Professor Guochun ZHAO (Mok Sau-King Professor) as corresponding author, alongside Emeritus Professor Min SUN and Dr Xing CUI, Postdoctoral Fellow and first author of the paper. Professor Jihua HAO of USTC served as co-corresponding author. By combining laboratory experiments with simulations, the team systematically revealed, for the first time, that in the ferruginous (Fe²⁺-rich) oceans of early Earth, common phyllosilicate minerals—including kaolinite, montmorillonite, nontronite, and lizardite—could effectively trap dissolved phosphate on their surfaces. This process was driven by an “Fe(II) bridging effect,” where Fe²⁺ ions formed chemical links between mineral surfaces and phosphate. As these mineral particles settled and were buried in sediments, this mechanism removed essential phosphorus from seawater, limiting its availability to support marine life. The findings have been published in Nature Communications. Phosphorus and the Early Earth Puzzle Phosphorus is an essential element for life and a key component of cellular membranes and nucleic acids. In many marine environments, its limited availability constrains primary productivity, making its cycling and bioavailability critical to understanding the co-evolution of the biosphere and geosphere. While interactions between minerals and dissolved phosphate play a vital role in the modern phosphorus cycle, how these interactions operated under the very different atmospheric and oceanic chemistry of the early Earth, particularly during the Archean, has remained unclear. Under anoxic and acidic weathering conditions of early Earth, the formation of Fe(III)-oxides was minimal, limiting their role as “phosphorus carrier”. Yet increasing attention has focused on clay minerals (a group of phyllosilicates), which possess strong phosphorus adsorption capacity and may have acted as a primary alternative for phosphorus sequestration. “Surface environments on the early Earth were vastly different from today, with oceans containing higher concentrations of dissolved Fe(II) and silica, and almost no sulfate,” explained the paper's first author, Dr Xing Cui. High silica levels could have competed with phosphate for mineral surface sites, while the scarcity of oxygen and low sulfate helped maintain iron in its Fe(II) form. “How these unique water chemistry conditions influenced the adsorption and transport of phosphorus by clay minerals is a key piece of the puzzle in understanding the environmental constraints on early life evolution,” said Dr Cui. The research team simulated the water chemistry of Archean rivers and oceans and systematically investigated the adsorption behaviour of phosphate onto common phyllosilicate minerals. The results showed that even at low to moderate concentrations of Fe2+ (20 μM to 0.1 mM), phosphate adsorption onto phyllosilicate surfaces was significantly enhanced, with a much stronger effect than that of other divalent cations such as Ca²⁺ and Mg²⁺. Although high concentrations of dissolved silica in the early oceans partly inhibited phosphate adsorption, the enhancing effect of Fe(II) remained dominant. “Through molecular simulations, we further uncovered the underlying mechanism,” said Dr Cui. “Fe(II) can form stable bridging complexes between the mineral surface and phosphate ions, substantially boosting adsorption efficiency. This ‘Fe(II) bridging effect’ was likely widespread in early iron-rich water bodies.” Phosphorus and Life–Environment Co-evolution By integrating experiment results with modelling, the team reconstructed a new picture of the early Earth's phosphorus cycle. During the mid to late Archean (ca. 3.2–2.5 billion years ago), as continents emerged and weathering intensified, rivers delivered large amounts of terrigenous detrital clay minerals to the oceans. In iron-rich rivers, these clays could adsorb phosphorus via the Fe(II) bridging effect, and following rapid burial in coastal sediments, act as an efficient sink that removes phosphorus from seawater. At the same time, ongoing seafloor weathering may have supplied nutrients, but newly formed phyllosilicates such as lizardite and nontronite, produced during seafloor weathering of mafic/ultramafic crust, could likewise efficiently adsorb dissolved phosphate with the aid of Fe(II), leading to its rapid burial and maintaining low levels of bioavailable phosphorus in the early oceans. “Our Monte Carlo simulations estimate that during the late Archean, the phosphorus burial flux facilitated solely by phyllosilicate adsorption could have been comparable to the total reactive phosphorus input by rivers at that time,” noted co-corresponding author Professor Jihua HAO. “This implies that phyllosilicate adsorption was a major sink in the early Earth’s phosphorus cycle, effectively removing phosphorus from the ocean water column.” This persistent phosphorus limitation may have delayed a significant rise in marine primary productivity, partially explaining why the Great Oxidation Event (GOE) occurred hundreds of millions of years after the emergence of oxygenic photosynthesis. This work intimately links mineral surface chemistry, aquatic geochemistry and biogeochemical cycles. “It not only deepens our understanding of the environmental and biological co-evolution of the early Earth, but also provides an analogue framework for investigating nutrient cycling and potential habitability of other planetary bodies, such as early Mars,” said Professor Guochun ZHAO, the corresponding author of the paper. In reducing, iron-rich aquatic environments, clay minerals may commonly play a key role as nutrient “regulators”.

Lighting the Spark at Nobel Week

“As the lights dimmed in Stockholm’s Concert Hall and a Nobel laureate stepped to the podium, I realised that my vision of what a career in physics could be had changed forever.” --Gordon Yat Long WONG, Year 5 Science Master Class student (majoring in Physics (intensive)) Meeting with Professor Omar YAGHI, Nobel Laureate in Chemistry 2025 Gordon (bottom left) with fellow participants in the Nobel Week programme Stepping into the crisp air of Stockholm, Sweden, for Nobel Week was more than an academic field trip, it marked a turning point in how I see my future in physics. As a student in the Science Master Class at HKU, I took on a dual role: an eager participant immersed in world-class physics and a student leader guiding a group of Hong Kong high schoolers throughout the programme. This unique vantage point allowed me to deepen my own scientific understanding while witnessing the “spark” of discovery ignite in the next generation. A Journey Beyond the Textbook The tour was designed to immerse us in the history and significance of the Nobel Prize while introducing us to cutting-edge scientific ideas, including macroscopic quantum phenomena and metal-organic frameworks. Learning how fundamental discoveries in physics, chemistry, and related fields have shaped our world reminded me of the long-term impact of scientific research. For me, the experience reinforced a deeper motivation: to pursue physics not only as an academic discipline but also as a way to contribute to society. As an aspiring researcher, I hope to one day follow in the footsteps of these pioneers by pursuing a PhD and contributing to the advancement of scientific knowledge. Nobel laureates, scientists & experts discussing global issues at the Nobel Dialogue Day. Wisdom from the Podium One of the most memorable experiences was attending the Nobel lectures and the Nobel Week Dialogue. Listening to Nobel laureates reflect on their discoveries and decades-long careers was both humbling and inspiring. What struck me most was how frequently they emphasised curiosity and persistence rather than immediate success. Many shared that their ideas were initially met with scepticism, and that their research journeys were marked by setbacks and uncertainty. As a physics student, I often find myself absorbed in problem sets and examinations, but hearing these stories was a powerful reminder that true scientific progress begins not with answers, but with meaningful questions and the courage to explore the unknown. The dialogue sessions also highlighted the deep connection between science and global challenges, demonstrating how scientific research is intertwined with society’s broader needs. Nobel Week Lights at Stockholm City Hall Science, Culture, and Community Beyond the academic programme, Stockholm itself offered a rich cultural dimension to the experience. Visiting the Stockholm City Hall and Concert Hall, venues where the Nobel ceremonies take place, made the entire experience feel more tangible and immediate. Walking through the city during the Nobel Week Lights lightshow and exploring museums allowed us to appreciate how deeply science is woven into Sweden’s cultural identity and history. Serving as a student leader during the tour added another meaningful layer to the experience. The role challenged my communication and mentorship skills as I guided younger students through the programme and supported their engagement with the lectures and discussions. Encouraging them to ask questions and connect with peers from around the world reminded me how important it is to make science accessible and exciting for the next generation. Their curiosity and enthusiasm reminded me of why I chose to study physics in the first place. Furthermore, interacting with students from different countries broadened my perspective. We exchanged ideas about cultural differences, science, and future aspirations. These interactions made me appreciate the international nature of science and the importance of collaboration across cultures. Carrying the Spark Forward Overall, the Nobel Week Tour was a valuable experience that strengthened my passion for physics and broadened my understanding of science in a global context. Much like the Grand Master tutorials at HKU Science, where leading scientists share the stories behind their discoveries, the opportunity to hear directly from Nobel laureates offered invaluable insight into the realities of a scientific career. It also allowed me to grow as an aspiring researcher and mentor. I am grateful to the HKU Admissions Office and the Faculty of Science for making this experience possible. More importantly, the journey has reinforced my commitment to carrying forward the spirit of curiosity, collaboration, and responsibility that defines the scientific community.

How Birds Thrive on Sugar

Most birds avoid sugary food. But hummingbirds, sunbirds, honeyeaters and some parrots live almost entirely on nectar or fruit to fuel their high-energy lifestyles. They consume huge amounts of sugar every day, without developing diabetes or other diseases that high-sugar diets can cause in humans. How do they do it? An international team, including Professor Simon Sin of the School of Biological Sciences, compared the genomes of four bird groups that independently evolved sugar-rich diets with the genomes of closely related birds that do not eat sugar. Even though these sugar-consuming birds evolved on different continents and millions of years apart, the scientists found something striking: evolution had affected some of the same genes in each group. Some genetic changes were unique to each lineage. But others appeared again and again, especially in genes involved in sugar processing and in regulating blood pressure and fluid balance. These changes help birds handle both the high sugar levels and the large volumes of liquid they consume from nectar. Hummingbird feeding on nectar, engineered by evolution for extreme energy demands. Image provided by Simon Sin. New Holland honeyeater in feeding posture. Image provided by Gerald Allen. Rainbow lorikeet perched among leafy branches. Image provided by Gerald Allen Out of thousands of genes examined, one stood out. A gene called MLXIPL, which plays a key role in sugar metabolism, was modified in all four sugar-eating bird groups but not in their non-sugar-eating relatives. Laboratory tests showed that in hummingbirds, this gene is much more active than in close relatives that do not feed on nectar. The findings suggest that evolution can arrive at similar biological solutions, even in species separated by millions of years. Understanding how these birds tolerate extreme sugar intake may also offer clues for studying human metabolic diseases. The research was led by scientists at Harvard University, the Max Planck Institute for Biological Intelligence, and the Senckenberg Research Institute and Natural History Museum Frankfurt. Professor Simon Sin contributed to sequencing and assembling the whole genomes of several sugar-feeding bird species.

HKU Marine Scientists Reveal Giant Clam Feeding Strategy Could Determine Their Future Survival

Giant clams (Tridacna gigas), members of the family Tridacnidae and among the most striking inhabitants of tropical coral reefs, are being driven towards extinction. Over-harvesting for the jewellery and aquarium trade, as well as for food, together with habitat loss and pollution, has severely reduced their populations. Climate change is now compounding these threats, making the situation even more precarious for these vulnerable animals. There are many species of giant clams in the wild. Some are disappearing faster than others, but the reasons for these differences are not yet fully understood. Other species appear plentiful, yet it remains unclear how far into potential decline they may actually be, and such species may therefore be inadequately protected. A research team from the Swire Institute of Marine Science (SWIMS) and the School of Biological Sciences of The University of Hong Kong (HKU) has helped address this question by developing an innovative mathematical model that allows conservationists to easily assess feeding strategies of different giant clam species. This knowledge can help conservationists to predict the future vulnerability of different giant clam species and identify those in need of timely protection. Close-up of the mantle of a giant clam (Tridacna gigas) in its natural reef habitat. The colourful tissue contains symbiotic algae that perform photosynthesis and supply energy to the host.

Understanding feeding strategies in giant clams Giant clams have two feeding methods. As animals, they eat organic matter by filtering it from the surrounding water. At the same time, they also rely on photosynthesis, much like plants do: symbiotic “partner” algae living inside the clam harvest sunlight and share the resulting energy with their hosts. To determine how much each species relies on these two energy sources, SWIMS researchers used chemical analysis to identify the unique nutritional pathways of six giant clam species. By measuring natural variations in carbon and nitrogen isotopes in both the clams and their symbiotic algae, and integrating these data into a mathematical model they developed — HERS (Host Evaluation: Reliance on Symbionts) — the team quantified how strongly each species depends on photosynthesis versus filter-feeding. Comparing these values across species showed that giant clams occupy different positions along a nutritional spectrum, with each species adopting a distinct feeding strategy. The fastest-growing and largest clams were found to rely more heavily on their symbiotic algae partners for energy. While this method may support rapid growth, it may also increase vulnerability. A strong dependence on light-harvesting symbionts could increase vulnerability to climate change, as these algae are sensitive to rising sea temperatures. Moreover, larger body size may further heighten exposure to over-harvesting, as such clams are more easily targeted. These findings suggest that differences in feeding strategy may be vital for assessing extinction risk, offering conservationists a new framework for prioritising protection efforts. “Giant clams are not just iconic reef residents, they are ecosystem engineers who play a crucial role in the health and resilience of coral reefs,” said Dr Isis GUIBERT, Postdoctoral Researcher at SWIMS and lead author of the study. “Understanding how these nutritional strategies differ among species is key to anticipating their future under environmental change.” “Our findings highlight that the very traits which make these clams so impressive also put them at greater risk,” explained Professor David BAKER, Interim Director of SWIMS and corresponding author of the study. “By revealing these hidden vulnerabilities, we can better focus conservation efforts where they are needed most.” “Our approach also sets the stage for future research on other symbiotic reef species, such as corals,” Professor Baker added. “It’s a step forward in understanding and protecting marine biodiversity.” This work, led by Professor David Baker and Dr Isis Guibert, was carried out in collaboration with researchers including Dr Cecilia Conaco and Dr Patrick Cabaitan from the University of the Philippines, Diliman, as well as Dr Ronnie Estrella, Director of the Semirara Marine Hatchery and Laboratory. The study was supported by Division of Ecology and Biodiversity PDF Research Award, the Research Grants Council Collaborative Research Fund (17108620), the Environment and Conservation Fund (ECF-67/2016 and CRF7G_C7013-19G), and the Department of Science and Technology of the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (DOST-PCAARRD; QMSR-MRRD-MEC-295-1449, 314-1542 and 314-1545).

HKU Astrophysicists Contribute to Interpreting a Possible First-Ever Einstein Probe Observation of a Black Hole, Tearing Apart a White Dwarf

An unprecedented high-energy cosmic event is offering new insights into extreme astrophysical processes. On 2 July, 2025, the China-led Einstein Probe (EP) space telescope detected an exceptionally bright X-ray source whose brightness varied rapidly during a routine sky survey. Its unusual signal immediately set it apart from ordinary cosmic sources, triggering rapid follow-up observations by telescopes worldwide. This research was coordinated by the EP Science Center of the National Astronomical Observatories, Chinese Academy of Sciences (NAOC), with participation from multiple research institutions in China and abroad. Astrophysicists from the Department of Physics at The University of Hong Kong (HKU), who are integral members of the EP scientific team, worked together with the broader collaboration to interpret the event, proposing that it may mark the moment when an intermediate-mass black hole tears apart and consumes a white dwarf star. If confirmed, this would be the first observational evidence of such an extreme black hole “feeding” process. The findings have been published as a cover article in Science Bulletin. A Cosmic Event that Broke the Usual Pattern This discovery was made possible by EP’s two unique and complementary X-ray instruments. During a routine sky survey on 2 July 2025, the Wide-field X-ray Telescope (WXT), which uses advanced lobster-eye micro-pore optics and offers a vast field of view with high sensitivity, detected a transient X-ray source exhibiting violent variability, later designated EP250702a (also known as GRB 250702B). Almost at the same time, NASA’s Fermi Gamma-ray Space Telescope recorded a series of gamma-ray bursts from the same region of the sky. The significance of the event became clear only after scientists examined WXT’s earlier observations. The telescope had already detected persistent X-ray emission from the exact location about a day before the gamma-ray bursts appeared—a sequence rarely seen in high-energy cosmic explosions. About 15 hours after the initial signal, the source erupted into a series of intense X-ray flares, reaching a peak luminosity of around 3 × 10⁴⁹ erg s⁻¹ and placing it among the brightest instantaneous outburst events ever observed in the Universe. “This early X-ray signal is crucial,” said Dr Dongyue LI, first author of the paper from the National Astronomical Observatories of China. “It tells us this was not an ordinary gamma-ray burst.” Thanks to the precise coordinates provided by WXT, several large telescopes worldwide rapidly followed up, successfully pinpointing the celestial object across multiple wavelengths and confirming its location in the outskirts of a distant galaxy. Subsequently, EP’s other instrument—the Follow-up X-ray Telescope (FXT) took over, tracking the source’s dramatic evolution. Over about 20 days, its brightness dropped by more than a hundred thousand times, while its X-ray emission shifted from higher-energy (“hard”) to lower-energy (“soft”) states. By combining data from the EP with follow-up observations across the electromagnetic spectrum, scientists found that EP250702a exhibited a set of unusual features that existing models could not fully explain. Its X-ray emission appeared before the gamma-ray burst, was extraordinarily bright, evolved on a remarkably fast timescale, and occurred in the outskirts of its host galaxy rather than at its centre—a pattern rarely seen in known high-energy cosmic events. Among the many theoretical scenarios considered, one explanation finally stood out: an intermediate-mass black hole tearing apart a white dwarf star. (b) Temporal evolution trend of the X-ray spectrum of EP250702a. The photon index increased significantly from about 1 in the early phase (indicating a 'hard' spectrum) to above 3 in the later phase (indicating a 'soft' spectrum). This clear 'hard-to-soft' transition, observed for the first time in such an event, suggests the possible emergence of a thermal radiation component at later times. Image credit: Einstein Probe Science Center, National Astronomical Observatories, CAS. HKU Astrophysicists Provide Key Model Support The HKU team played vital roles in data interpretation and theoretical modelling, leading to the identification of the underlying physical mechanism of the phenomenon. The team of Professor Lixin DAI from the Department of Physics and the Hong Kong Institute of Astronomy and Astrophysics (HKIAA) at HKU provided the crucial theoretical judgement that led to the focus on this model. As a co-corresponding author, she explained, “The white dwarf–intermediate-mass black hole model can most naturally explain its rapid evolution and extreme energy output.” Dr Jinhong CHEN, a co-first author of the paper and a postdoctoral fellow in the HKU Department of Physics, conducted in-depth numerical simulations to analyse the model. “Our computational simulations show that the combination of the tidal forces of an intermediate-mass black hole, combined with the extreme density of a white dwarf, can produce jet energies and evolutionary timescales that are highly consistent with the observational data,” he said. Professor Bing ZHANG, Director of HKIAA at HKU and a co-author of the paper, stated, “Hong Kong possesses an internationalised research vision and technical expertise in astronomy. The HKU team’s deep involvement and contribution to this significant discovery fully demonstrate the unique value and critical role of Hong Kong’s scientific research capabilities in the forefront of global scientific exploration.” Professor Lixin Dai added, “The robust discussion among international teams, each with their competing models to explain this event, is precisely what highlights its immense scientific value.” “The mission of the Einstein Probe is to capture unpredictable and extreme transient phenomena in the universe,” said Professor Weimin YUAN from the National Astronomical Observatories of China, Principal Scientist of the Einstein Probe mission. “The discovery of EP250702a fully demonstrates our capability to be the first to capture the Universe’s most extreme moments and further exemplifies China’s ability to make decisive contributions to international astronomical exploration.” If ultimately confirmed, this event would provide the first clear, direct evidence of an intermediate-mass black hole tearing apart a white dwarf and producing a relativistic jet. Such a discovery would help shed light on the long-missing population of intermediate-mass black holes and open new avenues for studying how black holes grow, the ultimate fate of compact stars, and the emerging field of multi-messenger astronomy. Project and Team Collaboration The collaborative team for this paper includes over 40 universities and research institutions, such as The University of Hong Kong, the National Astronomical Observatories of China, Anhui Normal University, Sun Yat-sen University, and the University of Science and Technology of China. Co-first authors of the paper are Dr Dongyue Li and Associate Researcher Wenda Zhang (National Astronomical Observatories of China), Dr Jun Yang (Zhengzhou University), and Dr Jin-Hong Chen (The University of Hong Kong). Co-corresponding authors are Associate Researcher Wenda Zhang, Researcher Weimin Yuan, and Researcher Chichuan Jin (National Astronomical Observatories of China); Professor Lixin Dai (The University of Hong Kong); and Researcher Chen Zhang (National Astronomical Observatories of China). The Einstein Probe satellite project is led by the Chinese Academy of Sciences. The mission also reflects extensive international collaboration, with key partners including the European Space Agency (ESA), the Max Planck Institute for Extraterrestrial Physics (MPE) in Germany, and the French National Centre for Space Studies (CNES). The research brought together more than 300 scientists from over 40 universities and research institutions in China and around the world, highlighting the strength of open science and large-scale international collaboration in tackling frontier scientific challenges.

For three decades, its fundamental lemma remained unproven until Professor Ngô's ingenious solution in 2009, which not only validated years of mathematical work but also opened new pathways within this profound theoretical structure. In 2010, Professor Ngô made history by becoming the first Vietnamese mathematician awarded the Fields Medal – mathematics' highest honour for researchers under 40. Along with the Abel Prize, these awards are widely regarded as the discipline's equivalent of the Nobel Prize. His transformative contributions to number theory and representation theory have had far-reaching implications across mathematical physics. His distinguished honours include the Clay Research Award (2004), Oberwolfach Prize (2007), Sophie Germain Prize (2007), and election as a Member of the American Academy of Arts and Sciences (2012) and a Foreign Member of the French Academy of Sciences (2016). Professor Ngô expressed his vision for joining HKU's academic community, "HKU's global connectivity and interdisciplinary culture create the ideal environment for transformative research. I am excited to collaborate with the University's brightest minds – not only to advance mathematics but to shape its future as a discipline that will redefine scientific discovery for decades to come." The arrival of Professor Ngô significantly strengthens HKU's position as a global leader in fundamental research, where world-class scholars unite to drive transformative interdisciplinary breakthroughs and ignite a spirit of intellectual daring that transcends academic boundaries.

HKU Biologists Discover Alternative Systems that Help Cells Control Genes

In mammals (left), previous studies show that most MBD3 binding sites overlap with MBD2 and the Nucleosome Remodeling and Deacetylase (NuRD) complex, while MBD2 also independently occupies additional regions enriched with DNA methylation (5-methylcytosine, 5mC). In Caenorhabditis elegans (C. elegans) (right), which lacks DNA methylation, MBD-2 (Cel-MBD-2) displays a dual binding pattern as in mammalian MBD2, despite lacking a methyl-binding domain. The majority of CelMBD-2 binds to genomic regions enriched with repressive histone modifications, such as H3K27me3 and H3K9me2/3, independently of NuRD. This model illustrates how MBD-2 can be guided by different epigenetic signals when DNA methylation is absent. (Image credit: Tsui, et al., 2026. Nature Communications) Researchers at the School of Biological Sciences of The University of Hong Kong (HKU) have uncovered how eukaryotic cells can control gene activity even after losing one of their major gene-regulatory systems during evolution. By studying a microscopic soil-living roundworm, the team revealed how an alternative, conserved epigenetic mechanism can take over when a common one is missing. The study has just been published in the interdisciplinary scientific journal Nature Communications. The findings provide new insights into how gene regulation adapts through evolution and may help scientists better understand disease mechanisms involving massive gene dysregulation, such as cancers, neurological disorders and autoimmune diseases. Cells must carefully control which genes are turned on and which are turned off throughout development to function properly. While the DNA sequence provides the genetic blueprint, gene expression is also regulated by epigenetic mechanisms — regulatory systems that influence when genes are turned on without changing the genetic code. This allows different cell types, such as nerve cells and muscle cells, to share the same DNA while behaving very differently. One common way cells control gene activity is through DNA methylation, in which a small chemical label, the methyl group, is added to cytosine, a specific base on DNA, forming 5-methylcytosine (5mC), to signal that certain genes should be kept switched off. 5mC is a key epigenetic mark in many animals and plants. However, some organisms, including the microscopic roundworm C. elegans, have lost DNA methylation multiple times during evolution. For a long time, scientists did not fully understand how these organisms could still regulate their genes properly without this major epigenetic system. In this study, Dr Emily Hok Ning TSUI, a Postdoctoral Fellow at the School of Biological Sciences at HKU, working in the laboratories of Professor Karen Wing Yee YUEN and Professor Chaogu ZHENG, together with Dr Charmaine Yan Yu WONG, also in the YUEN Lab, showed that when DNA methylation is absent, cells can switch to an alternative epigenetic mechanism. Instead of relying on chemical labels on DNA, cells use various histone modifications — different posttranslational chemical marks on histone proteins, the packaging proteins in which DNA is wrapped around inside the cell. The researchers focused on a protein called MBD-2 (methyl-CpG-binding domain protein 2), which in many animals recognises 5mC-marked DNA and helps silence or activate genes. Surprisingly, even though C. elegans lacks DNA methylation and 5mC, its version of MBD-2 remains essential. The HKU team found that in C. elegans, MBD-2 no longer reads DNA methylation signals. Instead, it is localised to genes in association with specific repressive histone marks, particularly H3K27me3, a histone modification known to be associated with gene silencing. When MBD-2 was deleted, the worms became infertile and developed severe physical defects. A large number of genes were no longer properly regulated, demonstrating that MBD-2 remains a key regulator of gene activity, even in the absence of DNA methylation. These findings reveal that epigenetic regulation is highly adaptable. When one gene-control system is lost, organisms can adapt to read different signals and maintain precise control in gene expression. “While scientists already know histone modifications and DNA methylation are highly interconnected and crosstalk with each other, this study in C. elegans showcases the functional conservation of the gene-regulatory NuRD complex on one hand, but also the plasticity and adaptability of epigenetic mechanisms in eukaryotes on the other hand,” said Professor Karen YUEN. This work may help scientists better understand the causes of human diseases, such as cancers, autism and inflammation, in which aberrant DNA methylation disrupts the regulation of many genes at the same time. Understanding how different epigenetic mechanisms can compensate for one another may also facilitate the development of alternative therapeutic approaches.

HKU and UCLA Scientists Uncover the Mechanism powering “Space Battery” above Auroral Regions

The dazzling lights of the aurora are created when high-energy particles from space collide with Earth’s atmosphere. While scientists have long understood this process, one big mystery remained: What powers the electric fields that accelerate these particles in the first place? A new study co-led by the Department of Earth and Planetary Sciences at The University of Hong Kong (HKU) and the Department of Atmospheric and Oceanic Sciences at the University of California, Los Angeles (UCLA) now provided an answer. Published in Nature Communications, the research reveals that Alfvén waves — plasma waves travelling along Earth’s magnetic field lines — act like an invisible power source, fueling the stunning auroral displays we see in the sky. By analysing how charged particles move and gain energy in different regions of space, the researchers demonstrated that these waves act as a natural accelerator, supplying energy that drives charged particles down into the atmosphere and produces the glowing auroral lights. To confirm their findings, the team analysed data collected by multiple satellites orbiting Earth, including NASA's Van Allen Probes and the THEMIS mission. The data provided solid evidence that Alfvén waves continuously transfer energy to the auroral acceleration region, maintaining the electric fields that would otherwise dissipate. “This discovery not only provides a definitive answer to the physics of Earth’s aurora, but also offers a universal model applicable to other planets in our solar system and beyond,” said Professor Zhonghua YAO of the Department of Earth and Planetary Sciences at HKU. Professor Yao leads a dedicated team in space and planetary science at HKU, which has established a reputation for high-impact research on planetary auroras. With deep expertise in the magnetospheric dynamics of planets like Jupiter and Saturn, the HKU team brought a critical planetary perspective to the study. “Our team at HKU has long focused on the auroral processes of giant planets. By applying this knowledge to the high-resolution data available near Earth, we have bridged the gap between Earth science and planetary exploration.” Professor Yao added. The research represents a model of interdisciplinary collaboration. The UCLA team, led by Dr Sheng TIAN, contributed extensive expertise in Earth’s auroral physics, while the HKU team provided the broader context of planetary space physics. The full research paper can be read here. Caption: Comparative schematic of auroral acceleration processes on Earth and Jupiter. The electron spectrum for the Earth was from DMSP F19 spacecraft, and the one for Jupiter was from Juno spacecraft. Both spectra exhibit a similar inverted V-shaped structure, indicating the presence of stable electric potential drops above the auroral regions. This similarity points to a common auroral acceleration mechanism across planets and illustrates how insights from planetary aurorae help interpret high-resolution observations near Earth.

DEPS at 30: A Community Shaped by Earth, Bound by Curiosity

In 2025, the Department of Earth and Planetary Sciences (DEPS) celebrated a milestone that was as meaningful as it was hard-earned: its 30th anniversary. The occasion marked not only three decades of teaching and research, but 30 years of building a community shaped by curiosity, care, and a shared fascination with the planet we call home. Where the Story Begins Every department begins with a founding date; far fewer begin with a sense of adventure. When the Department first opened its doors in 1995, it was a modest beginning powered by conviction. Led by founding Chair Professor John MALPAS and supported generously by the Hui family, the team set out to build something Hong Kong had long needed: a home for geoscience expertise, and a training ground to understand the city’s complex landscape. In those early years, learning unfolded far beyond lecture rooms. Staff and students traced coastlines and hillsides, read stories written in stone and strata, and learned to see the Earth not as a static object but as a living archive of time. Field boots, folded maps and shared laughter became part of daily life, underpinned by a simple belief—that to understand the Earth is also to learn how to care for it. From the outset, the Department embraced a clear dual mission: to master the fundamentals of geology while responding to the applied challenges of an increasingly urbanised world. “This balance between pure and practical science has shaped three decades of discovery, innovation and impact,” said Professor Zhonghui LIU, Interim Head of DEPS. A Homecoming Written in Memory “We’ve gone from tracing Hong Kong’s bedrock to studying planetary formation and climate futures,” Professor Liu reflected. “That’s why our celebration theme, ‘Beyond the Earth,’ feels so fitting. It captures not just our new scientific direction in space research, but the way this community has always tried to reach a little further than anyone expected.” The celebrations began on 28 November, like a long-awaited reunion. Alumni streamed back, some travelling hours, others crossing continents, to find their teachers, their friends, and, in many ways, a younger version of themselves. There were embraces held a moment longer, and jokes that resurfaced effortlessly. Nearly 50 alumni shared stories of their first field trips, their toughest assignments, and the sense of discovery that shaped their careers. What filled the room was not simply nostalgia. It was a quiet acknowledgement that the Department had not only given them knowledge, but a place to belong. Ideas by Day, a Community by Night The following day, 29 November, brought a a shift toward the future. At the anniversary symposium, 12 distinguished speakers reflected on the Earth beneath us and the worlds beyond, inviting more than 100 participants to imagine the possibilities of the coming decades. The keynote by Mr Tony Ying Kit HO, JP, added a thoughtful public dimension, grounding the scientific excitement in civic purpose. As evening settled, Loke Yew Hall glowed under evening lights as over 150 guests gathered for the Celebration Ceremony. The presence of 17 academicians of the Chinese Academy of Sciences (CAS) made the room feel both intimate and momentous, a reminder of how far DEPS’s reputation has travelled. Vice-President and Pro-Vice-Chancellor Professor Peng GONG and Dean of Science Professor Qiang ZHOU offered warm reflections —not only marking achievements, but honouring the people who made them possible. The Celebration Dinner that followed was alive with clinking glasses, renewed friendships, and the gentle hum of gratitude. More than 200 guests, including our staunch supporter Ms Sylvia HUI, came together with an ease that only a well-knit community can create. The Road Ahead The final morning, 30 November, captured the Department’s soul. In one room, Mok Sau-King Professor and Chair Professor Guochun ZHAO, joined by 18 CAS academicians, led deep discussions about the Department’s next strategic chapter: new research frontiers, collaborations, and responsibilities. It was the kind of quiet, serious work that shapes decades to come. Out on the calm waters of the Tolo Channel, a boat glided under the guidance of retired academic Professor L S CHAN. Alumni pointed toward familiar rock formations as the coastline passed like an old friend. The tranquility offered a space for quiet reflection, a chance for all to remember what first drew them to the field. As DEPS steps into its next decade, it carries a rare kind of warmth: a community built on curiosity, lifted by generosity, and sustained by the belief that understanding our world is a shared human calling.

HKU Chemists Develop First-in-Class Inhibitor Targeting a Key Epigenetic Regulator A New Strategy to Beat Lung Cancer

A research team led by Professor Xiang David Li from the Department of Chemistry at The University of Hong Kong (HKU), in collaboration with researchers from the Shenzhen Bay Laboratory and Tsinghua University, has made a breakthrough in epigenetic drug discovery. The team has successfully developed a first-in-class chemical inhibitor that precisely and selectively targets the ATAC complex, a critical cellular “switch operator” that activates tumour-promoting genes, opening a novel therapeutic avenue for non-small cell lung cancer (NSCLC). The findings were recently published in the top-tier journal Nature Chemical Biology, and multiple international patent applications have been filed. Histone Modifications as Genetic Switches in Our Cells Inside human cells, DNA is wrapped around protein structures called histones to form chromatin. Chemical modifications on histones function like genetic “switches”, determining whether genes are turned on or remain silent. Among these modifications, histone acetylation is one of the most important “on” switches that activate gene expression. This modification is catalysed by enzyme complexes known as histone acetyltransferases (HATs). The ATAC complex is one such HAT complex and plays a pivotal role in activating genes involved in cell growth and DNA replication. In cancers such as NSCLC, the ATAC complex becomes overactive, inappropriately flipping the “on” switch for numerous cancer-driving genes, fuelling uncontrolled tumour growth and spread. However, selectively inhibiting ATAC without disrupting other essential cellular complexes has remained a challenge in drug development. Precisely Targeting a Unique Component of ATAC Previous drug-development efforts focused on inhibiting GCN5, the catalytic subunit responsible for histone acetylation within ATAC. Nevertheless, GCN5 is also shared by several other HAT complexes, meaning that blocking it would inadvertently interfere with normal cellular functions and lead to significant side effects. To address this challenge, Professor Li’s team devised an innovative strategy targeting YEATS2, a protein subunit specific to the ATAC complex. Using structure-guided design, the researchers developed a potent and highly selective inhibitor of YEATS2, named LS-170. This inhibitor specifically binds to the acetyl-lysine recognition domain of YEATS2, preventing it from anchoring the ATAC complex to chromatin. Consequently, the complex is displaced from its target genomic regions, leading to a significant reduction in local histone acetylation and the “off” switching of oncogenes in NSCLC. Strong Suppression of Tumour Growth and Metastasis In NSCLC cell lines and animal models, LS-170 demonstrated strong efficacy in suppressing tumour growth and metastasis. Notably, the YEATS2 gene is frequently amplified in multiple solid tumours—including lung, ovarian, and pancreatic cancers—suggesting that this targeted strategy may hold broader therapeutic potential beyond lung cancer. This study represents the first chemical approach to precisely decode the function of a specific HAT complex, revealing ATAC's distinct role in maintaining gene expression programs in cancer. It also offers new insights for developing other complex-specific epigenetic drugs for human diseases. “In this work, we didn’t just create a potent and highly specific inhibitor that can suppress tumours, we also uncovered a novel strategy to target just one epigenetic complex out of several that share the same enzyme core. This approach opens up exciting possibilities for developing highly selective, complex-specific drugs that could potentially revolutionise treatments for human diseases,” said Professor Xiang Li, one of the corresponding authors of the paper. About the Research Team: The interdisciplinary collaboration was led by Professor Xiang David LI (HKU Chemistry), together with Professor Weiping WANG (HKU Pharmacology and Pharmacy), Researcher Xin LI (Shenzhen Bay Laboratory), and Professor Haitao LI (Tsinghua University). Co-first authors included Dr Sha LIU, Dr Yin Qiao WU, Dr Jinzhao LIU, and Dr Xinyi YAO. For more details, please refer to the journal paper: https://www.nature.com/articles/s41589-025-02132-7

HKU Astronomer Uses “China Sky Eye” to Reveal Binary Origin of Fast Radio Bursts

An international team of astronomers, including researcher from the Department of Physics at The University of Hong Kong (HKU), has uncovered the first decisive evidence that at least some fast radio burst (FRB) sources—brief but powerful flashes of radio waves from distant galaxies—reside in binary stellar systems. This means the FRB source is not an isolated star, as previously assumed, but part of a binary stellar system in which two stars orbit each other. Using the Five-hundred-meter Aperture Spherical Telescope (FAST) located in Guizhou, also known as the “China Sky Eye”, the team detected a distinctive signal that reveals the presence of a nearby companion star orbiting the FRB source. The discovery, published in Science, is based on nearly 20 months of monitoring an active repeating FRB located about 2.5 billion light-years away. A rare signal: the RM flare Changes in the polarisation properties of radio waves can reveal the environment around an FRB source. The team observed a rare phenomenon known as an ‘RM flare’—a sudden and dramatic change in the polarisation properties of the radio signal, likely caused by a coronal mass ejection (CME) from a companion star that contaminates the environment of the FRB source. ‘This finding provides a definitive clue to the origin of at least some repeating FRBs,’ said Professor Bing ZHANG, Chair Professor of Astrophysics of the Department of Physics and Founding Director of the Hong Kong Institute for Astronomy and Astrophysics at HKU, and a corresponding author of the paper. ‘The evidence strongly supports a binary system containing a magnetar—a neutron star with an extremely strong magnetic field, and a star like our Sun.’ Monitoring repeating FRBs with FAST Fast radio bursts are millisecond-long but extraordinarily bright radio flashes from beyond our Milky Way galaxy. While most FRBs are observed only once, a small fraction repeat, offering rare opportunities for long-term study and making it possible to detect unusual changes over time. These repeating sources have been closely monitored by FAST since 2020 through a dedicated FRB Key Science Programme co-led by Professor Bing Zhang. FRB 220529A was one of the active repeating FRBs continuously monitored with FAST. ‘FRB 220529A was monitored for months and initially appeared unremarkable,’ said Professor Bing Zhang. ‘Then, after a long-term observation for 17 months, something truly exciting happened.’ Tracing the signal through space FRBs are known for their near 100% linear polarisation. As radio waves travel through a magnetised plasma, their polarisation angle rotates with frequency—an effect known as Faraday rotation, measured by the rotation measure (RM). ‘Near the end of 2023, we detected an abrupt RM increase by a factor of twenty,’ said Dr Ye LI of Purple Mountain Observatory and the University of Science and Technology of China, the paper’s first author. ‘The RM then rapidly declined over two weeks, returning to its previous level. We call this an “RM flare”.’ Such a short-lived RM change is consistent with a dense magnetised plasma briefly crossing the line of sight. ‘One natural explanation is that a nearby companion star ejected this plasma,’ explained Professor Bing Zhang. ‘Such a model works well to interpret the observations,’ said Professor Yuanpei YANG, a professor from Yunnan University and a co-first author of the paper. ‘The required plasma clump is consistent with CMEs launched by the Sun and other stars in the Milky Way.’ Although the companion star cannot be directly observed at this distance, its presence was revealed through continuous radio observations with FAST and Australia’s Parkes telescope. ‘This discovery was made possible by the persevering observations using the world’s best telescopes and the tireless work of our dedicated research team,’ said Professor Xuefeng WU of Purple Mountain Observatory and the University of Science and Technology of China, the lead corresponding author. The discovery also supports a recent unified physical picture proposed by Professor Bing Zhang and his collaborator, in which all FRBs originate from magnetars, with interactions in binary systems enabling a preferred geometry that allows more frequent, repeating bursts. Continued long-term monitoring of repeating FRBs may reveal how common binary systems are among these mysterious sources. Collaboration and Support The research was carried out jointly by HKU, Purple Mountain Observatory, Yunnan University, the National Astronomical Observatories of the Chinese Academy of Sciences, and other collaborating institutions. Professor Xuefeng Wu (Purple Mountain Observatory), Professors Peng Jiang and Weiwei Zhu (National Astronomical Observatories), and Professor Bing Zhang of the Department of Physics at HKU served as co-corresponding authors. The project received support from the National Natural Science Foundation of China and other national and international grants from the collaborators. Observing time was provided by the FAST FRB Key Science Project (W.-W. Zhu and B. Zhang as Co-PIs), a FAST DDT program (coordinated by X.-F. Wu and P. Jiang), as well as FAST and Parkes PI projects (PIs: Y. Li and S. B. Zhang). For related research papers, please refer to the following link.

The scheme includes the Distinguished Research Achievement Award (DRAA), Outstanding Researcher Award (ORA), Outstanding Young Researcher Award (OYRA), Outstanding Research Student Supervisor Award (ORSSA), and Research Output Prize (ROP). The DRAA, ORA, and OYRA are awards that recognise individuals for their outstanding research accomplishments. The ORSSA is to recognise exemplary and effective supervisory guidance and support to their research postgraduate students. The ROP is a Faculty-based award to honour the best research output from each Faculty. The Teaching Excellence Award Scheme aims to recognise, reward and promote excellence in teaching at the University. Under the Scheme, there are four categories of awards, viz. University Distinguished Teaching Award, Outstanding Teaching Award (OTA), Early Career Teaching Award (ECTA) and Teaching Innovation Award (TIA). In addition to individual awards, both OTA and TIA offer team awards to recognise and encourage collaborative efforts and achievements in enhancing teaching and learning. Faculties should encourage their teachers with outstanding contributions to teaching and learning to apply for these awards.
