Climate change is significantly altering bioclimatic environments in China's dry–wet transition zones, according to a recent study published in the Journal of Hydrology.

The research conducted by scientists from the Institute of Atmospheric Physics at the Chinese Academy of Sciences, the UK Met Office and  Chinese Academy of Meteorological Sciences, addresses the challenges of assessing climate change impacts on vegetation ecosystems, which vary greatly across different spatiotemporal scales. The study examines how vegetation ecosystems respond and adapt to climate change, alongside the effects of soil water and heat processes. Bioclimatic environment change acts as a crucial link between climate change and local conditions affecting vegetation ecosystems.

"In areas where current vegetation models fall short, bioclimatic indicators offer an alternative for studying climate change impacts on ecological environments," notes Dr. Mingxing Li, the lead author of the study.

The study analyzes historical observations (1979-2018) and future scenario projections (2006-2100) under different climate scenarios. Among these scenarios is the Representative Concentration Pathway 8.5 (RCP8.5), which represents a high greenhouse gas emissions pathway leading to substantial global warming and climate change impacts. Under the RCP8.5 scenario, greenhouse gas emissions continue to rise throughout the 21st century, resulting in severe climate change consequences.

“We focus on ecological environments and habitat suitability for responsive ecosystems, considering climate change, bioclimatic water and heat conditions, and habitat suitability.” Says Dr. Li.

The findings reveal significant changes in bioclimatic environments across dry–wet climate transition zones, particularly under the RCP8.5 scenario. By the end of the 21st century, the local growing season length (GSL) could extend by 60 days, with 30% of the GSL facing heat stress. Despite some improvements in the middle parts of transition zones, overall water conditions worsen both in the air and soil. This leads to a northwestward shift of sustainable grasslands, with a reduction of approximately 131 million square kilometers in total area.

The study highlights the importance of winter and spring heat-water conditions in driving these changes and identifies climate transition zones as hotspots of ecosystem vulnerability, emphasizing the need for targeted impact assessment and adaptation studies.

"While our focus is on China, our findings offer insights for addressing climate change in other transition zones worldwide," adds Dr. Li.

An international study led by atmospheric researchers at PSI shows for the first time what portions of particulates in the air over northern India are especially harmful to health.

Nowhere else do people breathe air as dirty as in India. According to the World Health Organisation, as many as 1.3 million deaths per year on the subcontinent can be attributed to polluted air. With its National Clean Air Programme, the Indian government wants to enact countermeasures. To do this, decision-makers need to know what sources the particulates come from, how they are distributed regionally, and how harmful certain compounds are to human health. This important information has now been provided for the first time by a study led by members of the Laboratory for Atmospheric Chemistry at PSI, with partners from India, China, Germany, Denmark, France, Spain, and Switzerland. The researchers have not only determined the amounts and origins of particulates in the air, but also their oxidative potential – an important factor for the harmful effect a chemical compound can have on living cells and thus on health. The study has now been published in the journal Nature Communications.

The focus of the study was on the Indian capital New Delhi, and not for the first time. Of all the cities on earth, it is considered the metropolis with the highest concentration of particulates in the air. Over the past four years, the researchers had already gained groundbreaking insights into the air pollution there. In a study from 2023, they demonstrated for the first time that chemical processes run differently in the skies over New Delhi than in other major cities.

Incomplete combustion is the primary cause

This time the team was interested in the sources of particulate emissions and the pathogenic effect of certain substances. According to the study, incomplete combustion plays an especially big role in polluting the air. Even non-experts recognise this: «If it smokes, the combustion is incomplete,» explains Imad El Haddad. He and André Prévôt from the Laboratory for Atmospheric Chemistry at PSI led the latest study. Most notably, the burning of biomass or waste is a major contributor to the formation of particulates and smog. This includes the burning of cow dung for heating and cooking, which also produces high levels of particulate matter. Added to this is the outdated vehicle fleet, especially the small vehicles called tuktuks, widely used in India, and motor scooters with inefficient two-stroke engines.

To better assess the local and regional distribution of particulates, the team expanded the network of measuring sites compared to the previous study, adding two locations in the urban area of New Delhi, one in the area surrounding the capital, and one in Kanpur, around 500 kilometres southeast of the capital. The samples from these sites were examined at PSI by means of mass spectroscopy to determine their composition.

Particulates cause oxidative stress

The quantity of particulates in the air is an important factor – but not the only one. How harmful to health a dust particle is depends on its chemical composition and its oxidative potential. Simply put, this refers to the stress that a chemical compound puts on living cells and, ultimately, entire organs such as the lungs or blood vessels. This stress can lead to asthma, inflammation, hypertension, and other illnesses. The team determined this oxidative potential and correlated it with local and regional particulate sources. Despite the fact that the chemical composition of particulates was different at different locations, the high oxidative potential of organic aerosols in particular traces back to the incomplete combustion of biomass and fossil fuels, together with their organic oxidation products in the atmosphere. Compared to Europe or China, a larger proportion of these components are emitted locally, with a still substantial contribution from regional sources. This is consistent with the findings of last year’s study.

The research in New Delhi is funded by the Swiss Agency for Development and Cooperation. The first phase of the four-year programme is now coming to an end. For programme leader André Prévôt, it was a complete success and an important contribution to the assessment of air quality for the 900 million people living in the lowlands of the Ganges River. «Nevertheless, we still have a long way to go,» Prévôt says. «India needs strict measures and long-term monitoring, as well as societal change and better public awareness of environmental protection.» So it will still take some time before environmental conditions in northern India improve.

Air pollution and depression linked with heart disease deaths in middle-aged adults

EUROPEAN SOCIETY OF CARDIOLOGY

Athens, Greece – 26 April 2024:  A study in more than 3,000 US counties, with 315 million residents, has suggested that air pollution is linked with stress and depression, putting under-65-year-olds at increased risk of dying from cardiovascular disease. The research is presented today at ESC Preventive Cardiology 2024, a scientific congress of the European Society of Cardiology (ESC).1

“Our study indicates that the air we breathe affects our mental well-being, which in turn impacts heart health,” said study lead author Dr. Shady Abohashem of Harvard Medical School, Boston, US.

According to the World Health Organization, air pollution is estimated to have caused 4.2 million premature deaths worldwide in 2019.2 Mental illness has also been linked with premature death.3 This study examined whether air pollution and poor mental health are interrelated and have a joint impact on death from cardiovascular disease.

The study focused on particles less than 2.5 micrometres in diameter, also referred to as fine particles or PM2.5. They come from vehicle exhaust fumes, power plant combustion, and burning wood, and present the highest health risk. To conduct the study, county-level data on annual PM2.5 levels were obtained from the Centers for Disease Control and Prevention (CDC).4 PM2.5 exposure was categorised as high or low according to World Health Organization (WHO) standards. The researchers gathered data on the average number of days (age-standardised) that county residents experienced mental health issues—including stress, depression, and emotional problems—from the CDC.5 Each county was then categorised into three groups based on these numbers. Counties in the top third reported the most days of poor mental health (PMH).4 Age-adjusted premature cardiovascular mortality rates (under 65 years of age) per county, were obtained from the CDC.6 County characteristics were sourced from the County Health Rankings project.

The study included 3,047 US counties, representing 315,720,938 residents (with over 207 million aged 20 to 64 years and 50% females) in 2013. Between 2013 and 2019, some 1,079,656 (0.34%) participants died from cardiovascular disease before the age of 65 years. The researchers analysed the associations between pollution, mental health, and premature cardiovascular mortality after adjusting for factors that could influence the relationships.7

Counties with dirty air (high PM2.5 concentrations) were 10% more likely to report high levels of PMH days compared to counties with clean air (low PM2.5 concentrations). That risk was markedly greater in counties with a high prevalence of minority groups or poverty.  The link between PMH and premature cardiovascular mortality was strongest in counties with higher levels (above WHO recommended levels: ≥10 µm2) of air pollution. In these counties, higher levels of PMH were associated with a three-fold increase in premature cardiovascular mortality compared to lower PMH levels. Further, one-third of the pollution-related risk of premature cardiovascular deaths was explained by increased burden of PMH.

Dr. Abohashem said: “Our results reveal a dual threat from air pollution: it not only worsens mental health but also significantly amplifies the risk of heart-related deaths associated with poor mental health. Public health strategies are urgently needed to address both air quality and mental wellbeing in order to preserve cardiovascular health.”

Medscape removes education courses for doctors funded by tobacco giant

Company acknowledges “misjudgment” following a BMJ investigation, but medics call for a global ban on industry-funded medical education

BMJ

Medical education provider Medscape has bowed to pressure and agreed to permanently remove a series of accredited medical education courses on smoking cessation funded by the tobacco industry giant Philip Morris International (PMI), The BMJ and The Examination have found.

The global company has acknowledged its “misjudgment” in a letter to complainants and says it will not accept funding from any organisation affiliated with the tobacco industry in the future. .

The move comes after an investigation by The BMJ revealed the PMI deal and the widespread protests among doctors and academics in reaction to the partnership.

According to an internal Medscape document seen by The BMJ and the Examination, Medscape had planned to deliver 13 programmes under a multi-million dollar deal with PMI - called the "PMI Curriculum" - as well as podcasts and a "TV-like series.”

Other PMI-funded programmes with different continuing medical education (CME) providers have also emerged in Saudi Arabia and South Africa.

This apparent global push by the tobacco giant into certified medical education has been met with alarm and calls for certification bodies to issue a ban. 

In response to the criticism, a spokesperson for Philip Morris International told The BMJ: “Health agencies around the world have recognized the beneficial role that smoke-free products can play to improve public health. We are concerned that known special interest groups are actively blocking medical education that the U.S. Food and Drug Administration and medical community have determined are needed. These actions stand to prolong use and possibly increase consumption of combustible cigarettes—the most harmful form of nicotine use.”

But Tim McAfee at the University of California, San Francisco and former director of the Centers for Disease Control and Prevention Office on Smoking and Health, called PMI’s partnership with Medscape, “the ultimate example of the fox not only signing up to guard the hen house but offering to sit on the eggs. 

“It is a perversion of ethics surrounding continuing medical education to allow the very companies that caused and profit from the continuing epidemic of tobacco-related death and disease to be involved in any way,” he said.

Medscape claims that the course content complied fully with standards set by the Accreditation Council for Continuing Medical Education (ACCME), but Pamela Ling, director of the Center for Tobacco Control Research and Education at the University of California San Francisco, said if so, “then the standards need to be strengthened to ensure they don’t allow merchants of death to educate doctors.”

This view is supported in a linked editorial by Professor Ruth Malone at the University of California San Francisco, who says “health professionals, health leaders, their societies and professional organisations must demand that the bodies accrediting continuing medical education for clinicians enact policies banning content sponsored by tobacco-affiliated organisations.”

Health professional and patient organisations should also caution their members to be aware that the tobacco industry is attempting to influence patient care in favour of its products, she adds.

She highlights that Medscape is not the only company offering CME, and PMI may not be the only tobacco company working to influence health professionals in this way, and says similar offerings should be widely publicised and the relevant educational providers notified that tobacco industry sponsorship is unacceptable.

“The tobacco industry cannot be allowed to influence medical education, health practitioners, or patient care in this way as it desperately seeks to secure its future profits,” she concludes.

Isabelle Anguelovski, researcher at the Instituteof Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB), in Span, is one of the authors selected for the first-ever National Nature Assessment (NNA1). The U.S. Global Change Research Program announced the selection of authors who will contribute to the drafting of this document, which aims to shed light on the current challenges posed by climate change and nature loss.

To better understand the full picture of what is happening with nature, the NNA1 will provide a holistic picture of America’s lands, waters, wildlife, and ecosystems and the benefits they provide to the economy, health, climate, environmental justice, and national security. The Assessment will also look ahead at how nature might change in the future, and what those changes may mean for our economy and people’s lives.

The diverse team that will number over 150 experts was selected by the 11 leaders of the chapters in consultation with federal leadership, and they come to NNA1 from a range of organizations across the United States —from universities to federal, and state government, national laboratories, businesses, and nonprofits.

Isabelle Anguelovski will be participating in the chapter on Nature and Equity, led by Chris Schell, Assistant Professor at the University of California, Berkeley. Together with the other authors, they will bring deep experience and expertise in fields like ecology, health, economics, nature-based solutions, urban systems, environmental justice, agriculture, engineering, and much more. The author team also includes Indigenous Knowledge holders with place-based knowledge reflecting local experiences with nature.

Over the next two years, NNA1 authors will take stock of what nature provides in terms of its inherent worth, culture, health, and well-being, jobs and livelihoods, safety, and more, while looking ahead to understand how these benefits might change in the future. The final report is expected in late 2026.

Isabelle Anguelovski is an ICREA Research Professor at ICTA-UAB. She obtained a PhD in Urban Studies and Planning from MIT before returning to Europe in 2011 with a Marie Curie International Incoming Fellowship. Her research examines the extent to which urban plans and policy decisions contribute to more just, resilient, healthy, and sustainable cities, and how community groups in distressed neighborhoods contest the existence, creation, or exacerbation of environmental inequities as a result of urban (re)development processes and policies. Between 2016 and 2022, she was the leader of GreenLULUs, an ERC-funded project which examined green inequalities in 40 cities in Europe, the US, and Canada and she now coordinates a new POC ERC, ClimateJusticeRead, on predicting and preventing green gentrification.

 

Traffic noise, a novel risk factor for cardiovascular diseases

New analysis involving Mainz University Medical Center published in Circulation Research

UNIVERSITY MEDICAL CENTER OF THE JOHANNES GUTENBERG UNIVERSITY MAINZ

An international group of noise experts from the Copenhagen Cancer Institute (Denmark), the Swiss Tropical and Public Health Institute (Swiss TPH), the Perelman School of Medicine at the University of Philadelphia (USA) and the Department of Cardiology at the Mainz University Medical Center have analyzed recent epidemiological data and found strong evidence that transportation noise is closely linked to cardiovascular and cerebrovascular disease. As a result, the researchers call for traffic noise to be recognized as a risk factor for cardiovascular disease. The results of their analyses were published today in the renowned journal of the American Heart Association, Circulation Research.

Epidemiological studies have shown that traffic noise - such as road, rail, or aircraft noise - increases the risk of cardiovascular morbidity and mortality, with high-quality evidence for the development of cardiometabolic diseases such as ischemic heart disease, heart failure, stroke, and diabetes. According to the WHO, more than 1.6 million healthy years of life are lost every year in Western Europe due to traffic-related noise.

Night-time traffic noise, in particular, leads to frequent interruptions and shortening of sleep, an increase in stress hormone levels and increased oxidative stress in the vascular system and brain - and thus to the increased formation of free radicals.  These factors can promote vascular disorders, inflammation, and high blood pressure, thereby increasing the risk of cardiovascular disease. In the current review, the international team of authors from Denmark, the USA, Switzerland, and Germany focused on transportation noise's indirect, non-auditory, cardiovascular health effects.

The authors provide an updated overview of the epidemiologic research on the effects of transportation noise on cardiovascular risk factors and disease, discuss the mechanistic findings from the latest clinical and experimental studies, and propose new risk markers to address noise-induced cardiovascular effects in the general population. A recent analysis on traffic noise and cardiovascular disease integrated into the review article impressively demonstrates that for every 10 dBA, the risk of developing cardiovascular diseases such as heart attack, stroke, and heart failure increases significantly by 3.2 percent.

The authors also explain in detail the possible effects of noise on changes in gene networks, epigenetic pathways, circadian rhythm, signaling along the neuronal-cardiovascular axis, oxidative stress, inflammation, and metabolism. Finally, current, and future noise protection strategies are described and the available evidence on noise as a cardiovascular risk factor is discussed.

"With an increasing proportion of the population exposed to harmful traffic noise even after the COVID pandemic has ended, noise control efforts and noise reduction laws are of great importance for future public health," summarizes the lead author of the paper, Prof. Dr. Thomas Münzel, Senior Professor at the University Medical Center Mainz. "It is also important for us that traffic noise is now finally recognized as a risk factor for cardiovascular disease due to the strong evidence."

How the immune system learns from harmless particles

University of Bonn researchers demonstrate how tiny, innocuous particles strengthen the immune response

Our lungs are bombarded by all manner of different particles every single day. Whilst some are perfectly safe for us, others—known as pathogens—have the potential to make us ill. The immune system trains its response whenever it encounters such a pathogen. Yet researchers at the University of Bonn have now shown that even harmless particles help to improve the immune response and have published their results in the journal Nature Immunology.

An adult takes around 12 breaths a minute, filling their lungs with life-giving air. But they also breathe in all kinds of particles: harmless, germ-free organisms as well as fungal spores and pathogenic bacteria and viruses. “Whether we’re on public transport where people are coughing or in air-conditioned rooms where the air is full of fungal spores, our lungs are constantly being impacted by our environment,” says Professor Andreas Schlitzer, head of the Quantitative Systems Biology working group in the Life & Medical Sciences Institute (LIMES) at the University of Bonn. “It’s a challenge that the immune system in our lungs has to cope with throughout our lives. It has to adapt to ever-changing requirements, distinguish harmless particles from dangerous ones and react accordingly.”

However, the macrophages—cells of the innate immune system that are responsible for this task—know what they have to do. These “scavenger cells” identify pathogenic particles, destroy them reliably—for the most part—and store the attackers’ details in the immune system’s memory so that they can respond even more effectively next time. But what do the macrophages do with information on harmless particles? This was the question investigated by the working group led by Andreas Schlitzer, who is also a member of the Cluster of Excellence ImmunoSensation2 and the Life and Health Transdisciplinary Research Area at the University of Bonn. “The macrophages could simply forget all about innocuous particles because they don’t do us any harm,” Schlitzer explains. “However, we suspected that they retain information on them anyway and incorporate this knowledge into subsequent immune responses.”

Immune response modified by fungal spores

To test their idea, the researchers made mice breathe in beta-glucan, a sugar found inside the cell wall of a fungus called candida. “We’re exposed to these fungal spores all the time in our daily lives,” Schlitzer points out. “You get them in particularly high concentrations inside rooms with air-conditioning, for example, which are ideal places for them to live.” Although this particular fungus is perfectly safe for healthy people, it can put those with a weakened immune system—due to conditions such as HIV, for instance—at risk of serious illness.

The researchers then used high-dimensional single-cell technologies to study how the mice’s immune system reacted to harmful pathogens. They found that mice that were exposed to the beta-glucan first before being infected with legionella bacteria responded differently to the pathogens than those that were not. “The mice were resistant to the legionella infection or, to put it another way, managed to recover better thanks to their modified immune response,” Schlitzer explains, summing up the findings.

In order to adapt the immune response after coming into contact with harmless particles, macrophages use specific proteins that also play a role in diseases such as Alzheimer’s and obesity. Says Schlitzer: “If we’re able to modulate macrophages in specific ways, they could serve as ‘dials’ that we could tweak in order to treat these conditions.” This is what his working group will be researching going forward.

Institutions involved and funding secured

Besides LIMES at the University of Bonn, the study also involved the German Center for Neurodegenerative Diseases (DZNE), ETH Zurich, the Technical University of Munich, the University of Edinburgh, Heinrich Heine University Düsseldorf, the University of Zurich, the University Medical Center Hamburg-Eppendorf, the Bernhard Nocht Institute for Tropical Medicine, the Shanghai Institute of Immunology, the University Hospital Schleswig-Holstein​, the University of Exeter, East Tennessee State University, the Singapore Immunology Network and the German Center for Infection Research.

It was funded by various sources: an Emmy Noether Research Grant from the German Research Foundation (DFG); Collaborative Research Center 1454 Metaflammation and Cellular Programming; the Diet–Body–Brain (DietBB) research cluster; the European Research Council (ERC); the Wellcome Trust; the Medical Research Council Centre for Medical Mycology at the University of Exeter; a Sir Henry Dale Fellowship jointly awarded by The Wellcome Trust and the Royal Society; the Swiss National Science Foundation, the US National Institutes of Health (NIH); and a UK Research and Innovation (UKRI) Postdoctoral Fellowship Guarantee.

ExxonMobil Technology and Engineering Company (ExxonMobil), Nanyang Technological University, Singapore (NTU Singapore), and the Agency for Science, Technology and Research (A*STAR) have established the ExxonMobil-NTU-A*STAR Corporate Lab to develop solutions that would help lower carbon emissions, contribute to resource efficiency, and help build a more sustainable future. 

The Corporate Lab was officially launched today by Mr. Heng Swee Keat, Deputy Prime Minister, Coordinating Minister for Economic Policies and Chairman of the National Research Foundation (NRF). Corporate labs allow companies to draw on Singapore’s strong foundation of scientific capabilities to address real-world challenges. The partnership between industry and academia helps to strengthen the industry relevance of researchers’ R&D and enables innovative enterprises to stay globally competitive through gaining insights into new application possibilities.

Researchers in the S$60 million Corporate Lab will apply their expertise to advance global research efforts in lower-emissions technologies in five areas:

• Convert biomass into lower greenhouse gas (GHG) emission fuels for adoption in aviation, maritime and chemical sectors that are potentially more cost-effective and efficient;
   
• Carbon capture and utilisation using by-product industrial brines, such as desalination brine to produce alternative construction materials, turning industrial side streams into useful materials;
   
• Turn methane into low-carbon hydrogen and solid carbon materials: Develop new process technologies to produce hydrogen from natural gas, while identifying potential and new applications for carbon;
   
• Develop efficient carbon capture and carbonation technology for industry by-products: to produce solid carbonates for use in building and infrastructure applications;
   
• Large-scale application of carbon in concrete: Produce and validate concrete with carbon materials for large-scale deployment to enable, durable, and sustainable building and construction applications.

The new Corporate Lab - the latest addition to over 20 corporate laboratories across Singapore – is hosted by NTU’s Energy Research Institute @NTU (ERI@N) and A*STAR’s Institute of Sustainability for Chemicals, Energy and Environment (ISCE2), through the Industry Alignment Fund-Industry Collaboration Project (IAF-ICP) initiative and will work on joint research programmes over the next five years. These will be focused on helping to reduce greenhouse gas emissions and enhance resource efficiency.

The IAF-ICP initiative is a grant scheme under Singapore’s Research, Innovation and Enterprise 2025 (RIE2025) plan to increase the base of enterprises engaging in research and innovation activities in Singapore. It aims to foster industry-relevant public sector R&D efforts, and advances collaboration between public sector researchers with industry, with a line of sight to potential economic outcomes.

Working to meet Singapore’s and society’s growing needs for stable supplies of energy and essential products while also reducing greenhouse gas emissions in support of a lower-emission future, will require unprecedented innovation and collaboration at scale.

The research programmes identified by the Corporate Lab can contribute to Singapore’s energy security, unlock new socio-economic potential, and help support its progress towards a net-zero future.

NTU Vice President (Industry) Professor Lam Khin Yong said: “The partnership between NTU, ExxonMobil and A*STAR is an example of how close collaboration with academia, industry, and public agencies is crucial in developing innovative solutions to address real world challenges. This is in line with NTU’s long-term strategic efforts to tackle grand challenges facing humanity and will build on NTU’s deep expertise in sustainability to help amplify Singapore’s on-going efforts to develop low carbon solutions. The new corporate lab ensures that our research results have the opportunity to be translated into impactful, real-world innovations, bringing us closer to a cleaner and greener future.”

ExxonMobil Asia Pacific Pte. Ltd. Chairman and Managing director Geraldine Chin said: “I’m excited that ExxonMobil with its global leadership in energy and material technology, will continue to work with Singapore’s world-class researchers to accelerate research development for a lower-carbon future. Our involvement in the translational R&D stages can help scale up projects for commercial deployment. We look forward to collaborating with our corporate lab partners on innovative discoveries that can help change our industry and the world.”

A*STAR’s Assistant Chief Executive, Science and Engineering Research Council, Professor Lim Keng Hui said, “A*STAR’s collaboration with ExxonMobil and NTU signifies our shared commitment to achieving a carbon circular economy through technological innovations. The corporate lab combines ExxonMobil’s industry expertise with A*STAR’s and NTU’s cutting-edge research, to accelerate technological deployments for a more resource-efficient future in support of Singapore’s net zero goals.”

Singapore Economic Development Board Executive Vice President Lim Wey-Len said: “The Corporate Lab by ExxonMobil, NTU and A*STAR is a first in Singapore launched with a global energy player. The joint lab is a valuable addition to our ecosystem that will spur solutions for a greener future, while developing home-grown talent in R&D and sustainability here. Singapore is a location where innovation and diverse partnerships thrive, and we continue to welcome like-minded players to join us in developing low carbon solutions from Singapore for the world.”

Leading the Corporate Lab as co-directors are NTU’s Professor Xu Rong, School of Chemistry, Chemical Engineering and Biotechnology and Research Director for Engineering and Physical Sciences, and Dr. Saifudin Abubakar, ExxonMobil  strategic portfolio manager for technology & engineering research, and advisor to the Singapore Energy Consortium.
 

Training home-grown carbon circular economy experts

The five research programmes undertaken by the new Corporate Lab are expected to generate several technical disclosures, patents, and prototypes. Additionally, it provides an excellent platform to train a talent pool of graduates, research engineers, postgraduates, and postdoctoral fellows in the emerging field of carbon circular economy.

The Corporate Lab will bring together more than 50 researchers, postgraduate and undergraduate students, and engineers from ExxonMobil, NTU, and A*STAR. The collaboration presents unique opportunities for our talent to grow practical skillsets and gain insights beyond research capabilities.
