Introduction

In a highly urbanized society with tight resources and a diverse population structure, research is no longer just a theoretical exercise in the lab; it is increasingly a direct response to the complex problems of real-world governance. Two studies featured recently at the annual symposium of the Campus for Research Excellence and Technological Enterprise (CREATE) vividly show this trend: one focuses on maritime accident emergency management, while the other examines lighting and health. The first uses a digital twin system to simulate ship collisions, fires and oil-spill spread in Marina Bay, and uses artificial intelligence to help authorities assess danger in real time. The second studies how appropriate lighting affects childhood myopia prevention and the physical and mental health of older adults, seeking to guide public-health strategy with more detailed human data.

These two studies, though from different fields, share the same core logic: they use data, models and cross-disciplinary collaboration to turn complex problems into governance objects that can be predicted, intervened in and optimized. This not only shows how science responds to social needs, but also reflects Singapore's long-term planning in applied research and urban resilience.

Digital Twins: Turning Maritime Emergency Response from "Reactive" to "Predictive"

A Marina Bay collision, a vessel fire, smoke rising, and an oil spill spreading - what looks like a real maritime emergency is in fact a pre-set simulation scenario created by the research team. The goal is to develop a digital twin system that can provide higher-precision real-time support for maritime incident management. A digital twin is, in simple terms, a virtual "digital mirror" that maps the real world in sync, allowing the system to keep updating its state as conditions change and predict how things may develop.

The study is led by France's National Centre for Scientific Research, funded by Singapore's National Research Foundation, and is still in the proof-of-concept stage. It is expected to be completed in early 2027. The team combines physics theory, public data and AI forecasting power to build a dynamic simulation model. The system can incorporate environmental variables such as wind speed, wind direction and current direction, and then judge the likely spread of pollution, fire behavior and the areas that may be affected.

The value of this capability is that it moves emergency management from "after the fact" to "before the fact." After a maritime incident, the golden rescue window is often very short. Command teams must deal not only with rescuing people, but also with pollution control, channel clearance and public safety alerts at the same time. If the system can provide highly credible simulations at the very start of an incident, rescue agencies can more quickly set up zone closures, vessel deployment and pollution containment plans, reducing secondary risks and guiding the public away from affected waters through more accurate information.

From a broader perspective, the value of such systems is not limited to any single incident. As global port traffic rises and maritime activity becomes more frequent, maritime safety has become an important part of urban resilience. As an international shipping hub, Singapore relies heavily on real-time decision-making for channel management, port safety and marine environmental protection. If digital twin technology matures, it will provide a replicable and scalable technical framework for risk governance in port cities.

Interdisciplinary Research Platforms: From the Lab to Real-World Use

The reason this maritime study stands out is also closely tied to its platform. Founded in 2007, CREATE has long attracted overseas research institutes, creating a local and international ecosystem where teams work together. This collaborative model helps break down disciplinary boundaries so that knowledge from engineering, computing, physics, environmental science and even public administration can come together around the same problem.

In today's research environment, a single discipline often cannot solve complex urban problems on its own. Take maritime emergency response: a marine physics model alone is not enough to support real decisions. The system also needs machine-learning algorithms to speed up forecasts, public data to train the model, and a sufficient understanding of command processes and social behavior to truly serve emergency departments. In other words, interdisciplinary work is not an add-on; it is a necessary condition for solving complex real-world problems.

This research path also reflects a clear feature of Singapore's science policy: a strong focus on innovation that can be put into practice. Government funding is not only about paper counts; it also cares about whether research can turn into social benefit, industrial value and governance capability. The digital twin system is a typical example of this direction: it is both a testbed for cutting-edge technology and an important tool for upgrading public safety systems.

Lighting and Health: Using Environmental Science to Address Public Health and Aging

In contrast to the maritime emergency research, another study on display turns to a more everyday health issue. A project by the National University of Singapore and the multidisciplinary platform TUMCREATE focuses on the role of "appropriate lighting" in preventing childhood myopia, slowing myopia progression and supporting the physical and mental health of older adults. The project began in 2024, and results are expected next year.

For the older-adult segment, the team recruited 75 participants aged 60 and above. Early results show they spent an average of about 169 minutes each day in an environment with 250 lux of light. Two hundred and fifty lux is not strong sunlight; it is closer to the soft light of sunrise or sunset, or a well-lit indoor space. While the number seems ordinary, it points to an important fact: many people's daily light exposure may be uneven, and that imbalance can quietly affect sleep, mood, activity rhythm and cognitive performance.

Dr. Reishaya, who participated in the study, said many Asians worry about tanning or heat and therefore avoid sunlight, while some older adults living alone also spend long hours indoors, leading to too little natural light. This is especially important in an aging society. As people grow older, the body's sensitivity to circadian changes may decline. If they remain in weak or unstable lighting for long periods, sleep quality, mental state and daytime activity levels may all suffer.

So the research team is not only raising a medical question, but also proposing a practical lifestyle intervention: can reminders, environmental tweaks or schedule adjustments help older adults get more appropriate light exposure? If the answer is yes, then such low-cost interventions could have real meaning for community care and home-based elder support. Compared with relying on strong drugs or complex treatments, proper light management is more like an "environmental prescription" that can continuously improve health in daily life.

From Myopia Prevention to Healthy Aging: The Larger Meaning of Light Research

Another layer of value in the study is that it lifts "light" from a simple physical condition to a health-management variable. In the past, lighting was often seen as a background factor. Today, more and more research shows that light affects not only visual development, but also biological clocks, sleep rhythm, mental state and cognitive function. For children, too little outdoor light may be linked to a higher myopia risk; for older adults, moderate natural light may help stabilize routines, lift mood and maintain daily activity.

That means future public-health policy may need to look beyond diet, exercise and medication, and also take the environment into account. For example, schools could add more outdoor activity time, community centers could optimize lighting, care services could design light reminders for seniors living alone, and outdoor activity advice could be adjusted dynamically according to season and weather. These measures may seem small, but they can deliver significant gains at the population level.

Conclusion

From digital twin simulations of maritime accidents to empirical research on light and health, these two projects together show a clear trend: to deal with the complex risks of modern urban governance, research must be closer to reality, more collaborative and more application-oriented. AI, physical modeling and public data are giving maritime emergency management unprecedented predictive power; meanwhile, lighting research reminds us that health comes not only from hospitals and pharmacies, but also from the environments we live in every day.

In the future, truly valuable research will not only ask "Can it be done?" but also "How can more people benefit?" These two Singapore studies show exactly that kind of innovation path: one that faces reality, serves society, and balances frontier science with public well-being. Whether it is protecting maritime safety or improving population health, the ultimate goal of technology remains the same: to make cities run more reliably and help people live more safely and healthily.
