The field of exposomics is revolutionizing health science by unlocking the power of advanced technologies to study the complex interactions between environmental, social, and psychological factors that shape our biology. By analyzing the molecular fingerprints left in our bodies from every breath we take, every meal we eat, and every environment we encounter, researchers are uncovering new insights into disease prevention and personalized medicine.

Led by the Banbury Exposomics Consortium, an interdisciplinary group of scientists gathered at Cold Spring Harbor’s Banbury Center to define the core principles of this rapidly evolving field. Gary Miller, PhD, a foremost expert in exposomics and faculty member at Columbia University Mailman School of Public Health, was the lead organizer of the Consortium.

Exposomics explores how environmental factors such as pollutants in our water and food, social stressors, and psychological factors shape our biology. By studying these combined exposures, researchers can uncover how they collectively influence health, from metabolism and heart function to brain health and disease risk.

The young field is already proving its transformative potential. Researchers analyzing molecular evidence identified a specific industrial solvent as the culprit behind kidney disease clusters among factory workers. In another study, scientists merged satellite pollution mapping with residential location information to reveal how airborne particulates prematurely age the brain.

These discoveries are made possible by cutting-edge technologies and tools such as wearable sensors that track chemical exposures in real-time, satellite imagery that maps pollution down to city blocks, and ultra-sensitive mass spectrometers that detect compounds present at just one part per trillion.

While genetics provides our biological blueprint, it explains only a fraction of chronic disease risk. The exposome captures everything that happens to us, from industrial chemicals to social stressors. Unlike traditional studies examining single exposures in isolation, exposomics integrates advanced tools to understand how environmental, social, and psychological factors collectively interact with our biology.

Systematically analyzing these complex interactions can improve drug development, uncover hidden drivers of disease, and address health disparities. The approach bridges precision medicine and population health.

Miller and colleagues outline critical priorities for advancing exposomics, including the development of more sensitive technologies, creating a human exposome reference to enable analysis and contextualization at the population scale, and implementing standardized protocols to enable AI-driven analysis of complex datasets.

Newly launched U.S. and European exposomics hubs now provide the infrastructure for worldwide collaboration, standardizing methods, harmonizing data, and training researchers in the cross-disciplinary skills needed to advance this field.

“We’re now building the first systematic framework to measure how all exposures — from chemical to social — interact with biology across the lifespan,” says Miller. “Our goal is to create actionable strategies for healthier lives.”

Pregnant women who suffer from metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease, are more likely to give birth prematurely. A new study published in the journal eClinicalMedicine has found that these women have a significantly higher risk of preterm birth, and this increased risk cannot be attributed solely to their weight or obesity.

According to the research conducted by Karolinska Institutet, one in five people in Sweden may have MASLD, while globally, it could affect as many as three out of ten individuals. Common risk factors for developing the disease include metabolic disorders like type 2 diabetes and being overweight or obese. The study’s findings are based on Swedish registry data and included a total of 240 births among women with MASLD, along with 1140 matched births from the general population.

Alarmingly, the research revealed that women with MASLD were more than three times as likely to give birth prematurely compared to those without the disease. This increased risk persisted even after adjusting for factors such as weight and metabolic disorders. The study’s lead author suggests that this association may not solely be due to a high BMI, implying that the liver disease itself could have negative effects on pregnancy outcomes.

Moreover, women with MASLD had a 63 percent higher risk of caesarean section compared to the control group. However, this increased risk seemed to be explained by their high BMI, as no significant difference was observed when comparing them to overweight or obese women without fatty liver disease.

While the study’s findings are concerning, it is essential to note that MASLD itself did not increase the risk of congenital malformations in the children born to these women. The authors acknowledge that their research may have been influenced by other factors and emphasize the importance of closely monitoring pregnant women with MASLD to reduce the risk of complications.

The study’s conclusions highlight the need for specific recommendations regarding pregnancy care for women with MASLD, which could potentially be added to clinical guidelines for managing the disease.

As we age, our bodies undergo various changes that can impact our physical and mental well-being. While some of these changes are inevitable, research suggests that incorporating certain foods into our diet can help promote healthy aging.

A recent study conducted by researchers from Edith Cowan University, Queen’s University Belfast, and Harvard T.H. Chan School of Public Health found that consuming higher intakes of black tea, berries, citrus fruits, and apples could lower the risk of key components of unhealthy aging, including frailty, impaired physical function, and poor mental health.

The study analyzed data from 62,743 women and 23,687 men over a period of 24 years. The findings revealed that women with the highest flavonoid intakes had a 15% lower risk of frailty, a 12% lower risk of impaired physical function, and a 12% lower risk of poor mental health compared to those with the lowest intakes.

While fewer associations were observed in men, higher flavonoid intake was still linked to a lower risk of poor mental health. The researchers suggested that regularly consuming flavonoid-rich foods could support healthier aging by reducing the risk of frailty, physical decline, and poor mental health.

The study’s lead author, Dr. Nicola Bondonno from Edith Cowan University, emphasized the importance of medical research in promoting healthy aging. “Our goal is not just to help people live longer but to ensure they stay healthy for as long as possible,” she said.

Professor Aedin Cassidy from Queen’s University Belfast added that flavonoids have been shown to reduce oxidative stress and inflammation, supporting blood vessel health, and even helping to maintain skeletal muscle mass – all of which are crucial for preventing frailty and maintaining physical function and mental health as we age.

The researchers noted that incorporating three servings of flavonoid-rich food into one’s diet could lead to a 6% to 11% lower risk across all three aging outcomes in females, and a 15% lower risk of poor mental health in males. This highlights the potential for simple dietary modifications to impact overall quality of life and contribute to the optimisation of healthy aging.

Overall, this study underscores the importance of incorporating flavonoid-rich foods into our diet to promote healthier aging. As Professor Eric Rimm from Harvard T.H. Chan School of Public Health noted, “These findings underscore the potential for simple dietary modifications to impact overall quality of life and contribute to the optimisation of healthy aging.”

The Cilento Initiative on Aging Outcomes (CIAO) study has been a decade in the making, and this month, researchers will gather in Acciaroli, Italy to review their progress and plan their next steps. Launched in 2016, the CIAO study seeks to identify key factors that promote healthy aging and extreme longevity.

The region of Cilento in southern Italy is home to a remarkable 300 residents who are over 100 years old and in robust health. This area was also the original source of research for Ancel Keys, the American physiologist who studied the influence of diet on health and promoted the benefits of the Mediterranean diet.

Scientists hope to reveal the longevity secrets of the Cilento region by using an array of tools to measure metabolomics, biomes, cognitive dysfunction, and protein biomarkers for risk of heart disease, Alzheimer’s, kidney disease, and cancer. They will also conduct psychological, social, and lifestyle surveys to gain a more comprehensive understanding.

“There is no single secret to living a long, healthy life,” said Salvatore Di Somma, MD, the study’s lead Italian investigator. “It is many secrets, most of which we are only beginning to understand and more importantly, learn how they might be applied to the well-being of everybody.”

The CIAO study is a multi-institution collaboration that includes Sanford Burnham Prebys, an independent nonprofit biomedical research institute in San Diego, the Sanford Stem Cell Institute at University of California San Diego, University La Sapienza in Rome, and Great Health Science.

A symposium will take place on May 22-23, featuring scientists describing their work and findings. The event is titled “CIAO Study: A decade of science on healthy aging, stem cells, and the revealed secrets of longevity.” Understanding how we age and how we might age better is a timeless pursuit, said David Brenner, MD, president and CEO of Sanford Burnham Prebys.

Current CIAO projects are leveraging genetic, epigenetic, transcriptomic, metabolic, proteomic, and environmental analyses to identify key contributors to extreme longevity. Researchers are using induced pluripotent stem cell (iPSC) derived from the centenarians to model age-related and metabolic stresses in human 3D organoids.

“This study will provide new insights into the development of regenerative medicine strategies for promoting healthy aging and treating age-related conditions,” said Tatiana Kisseleva, MD, PhD, professor of surgery at UC San Diego School of Medicine. Preliminary findings are expected to be presented at the symposium.
