The Simpson Neutron Monitor Network includes ground-based cosmic ray detectors at multiple locations, including Haleakalā in Hawaiʻi, supporting space weather research and real-time monitoring.

The three-year, $922,511 continuing award will support the operation and maintenance of the Simpson Neutron Monitor Network, a global system of ground-based detectors that measure cosmic rays—high-energy particles that travel through space and constantly strike Earth’s atmosphere.

Led by ÌÇÐÄÊÓÆµ Mānoa Chair and Professor Veronica Bindi and co-principal investigator Nikolay Nikonov, the project provides critical data used by researchers, space weather forecasters and industries that rely on sensitive technology.

Sun influence, space weather

Neutron monitors are ground-based particle detectors that measure secondary particles produced when cosmic rays and solar energetic particles interact with Earth’s atmosphere. These measurements are essential for understanding how solar activity influences the heliosphere and the near-Earth radiation environment.

At ground level, cosmic rays are not hazardous because Earth’s atmosphere and magnetic field provide substantial shielding. However, radiation exposure is significantly higher at aviation altitudes and in space, where the protective atmosphere is reduced. For this reason, neutron monitor data is used by space science researchers, space weather forecasters, aviation and satellite communities, and industries concerned with radiation effects on microelectronics.

Attendees gather for a blessing for two new neutron monitor stations on Haleakalā.

“This award strengthens the University of Hawaiʻi’s role in national space weather research and infrastructure,” Bindi said. “Neutron monitors provide a unique ground-based view of energetic particles from the Sun and from the galaxy. These data are critical for both fundamental heliophysics and practical space weather applications.”

The network’s detectors collect continuous measurements of cosmic ray intensity from locations around the world. Researchers use the data to study solar storms, energetic particles released by the Sun and other phenomena occurring throughout the solar system. The project also supports specialized tools, including a Ground Level Enhancement Alert System that provides real-time notifications when unusually large solar particle events are detected.

The award supports research infrastructure that enables continuous, long-term measurements needed to understand solar modulation, detect major solar particle events and provide data to the international space weather community.

The award complements ÌÇÐÄÊÓÆµâ€™s broader space weather activities, including neutron monitor infrastructure in Hawaiʻi that helps fill an important observational gap in the Pacific region, and the development of space radiation monitoring and forecasting capabilities at ÌÇÐÄÊÓÆµ Mānoa. Together, these efforts support a growing national need to better identify, characterize and mitigate space weather events that can affect infrastructure, society, aviation, satellites, space missions and government functions.

“This is an important step toward building a stronger space weather capability at ÌÇÐÄÊÓÆµ,” Bindi said. “Our goal is to connect high-quality observations, advanced analysis and forecasting tools to support science, education and operational awareness.”

The network honors John A. “Jack” Simpson, a pioneer of cosmic ray research whose neutron monitor design became a foundation for long-term space weather observations worldwide.

A University of Hawaiʻi at ²ÑÄå²Ô´Ç²¹ research team is working to improve lung cancer treatment by developing new ways to predict which patients will respond to immunotherapy and identify treatments that can overcome resistance. The five-year, approximately $3.26 million National Institutes of Health grant supports the (JABSOM) and the research team.

The project, “Novel Biomarkers for Predicting and Improving Immunotherapy Response in Lung Cancer,” runs through July 2031. It is led by Youping Deng, professor and director of JABSOM‘s Bioinformatics Core Facility, who also serves at the ÌÇÐÄÊÓÆµ Cancer Center’s Biology Program and Genomics and Bioinformatics Shared Resource.

By combining a predictive biomarker (a biological molecule that helps predict how a patient will respond to treatment) with a potential therapeutic approach, the project aims to help physicians select treatments more precisely while creating new options for patients whose tumors do not respond to existing immunotherapies.

While immune checkpoint inhibitors (ICIs)—a type of immunotherapy that blocks the proteins cancer cells use to hide from the immune system, allowing it to better recognize and attack them— have transformed non-small cell lung cancer treatment, resistance remains a hurdle, and current biomarkers are not always accurate in predicting patient response.

“Our team has discovered a new biomarker that may more effectively predict treatment response, as well as a promising therapeutic target that could help overcome ICI resistance,” Deng said. “This NIH R01 grant will allow us to validate these discoveries and move them closer to clinical application.”

The research team includes JABSOM‘s Shaoqiu Chen and Li Ma, and the ÌÇÐÄÊÓÆµ Cancer Center’s Owen Chan and Xin Chen.

Maui Lahaina

Three years after the August 2023 wildfires on Maui, substantial steps forward have been made, but important gaps remain, according to a new report from the (ÌÇÐÄÊÓÆµERO) released on August 11. Housing has stabilized for many affected families, with more households in permanent homes, and some able to return to their communities. But employment and incomes have moved little over the past year. The report presents findings from the Maui Recovery Survey, an ongoing survey of people who lived, worked, or owned a business in West Maui or Kula at the time of the disaster.

Key findings from the August 11 report:

  • Displacement has declined modestly. The share of households no longer displaced rose modestly over the past year, and fewer are displaced from both their home and West Maui. Of those displaced from both their home and West Maui in early 2025, about one in six have returned to West Maui but not yet to their home. Displacement also continues to extend beyond the burn area, where the share displaced from their home but remaining in the same area has risen.
  • Housing stability has continued to improve. Homeownership has recovered slightly from 38% to 42%. For some, relief programs met needs that predated the fires. About 60% of those who were unhoused or in informal arrangements before the disaster had a rental by 2025, and a further 20% by 2026. About two-thirds of fire-affected households now live in permanent housing, up from just over half in early 2025. Households are also moving far less than in the first two years, and among those still in temporary arrangements the share at the same address for more than a year has tripled to almost two-thirds. However, overall rates of temporary and unstable housing remain elevated.
  • Rental costs have eased for smaller properties, but remain heightened for larger units. Median rent for studios and one-bedrooms has fallen to roughly its pre-fire level by May 2026. Rents for larger units have stayed broadly flat and well above pre-disaster levels. Overall, almost half of fire-affected renters now pay less than before the fires (largely because of rental assistance), but at the same time almost 40% pay more. The share of households receiving full or near-full rental assistance has been cut by more than half, from 37% in January 2025 to 15% in May 2026.
  • Employment continues to be an area of limited progress. 42% of fire-affected people work full-time, unchanged from a year earlier and still well below the 62% who did so before the fires. Unemployment has fallen from 10% to 8%, but exits from the labor market through retirement or no longer seeking work have risen from 26% to 30%. Even among working-age people, more than one and a half times as many are out of the labor force as before the disaster. Among people employed in the visitor industry before the fires, about two-thirds still work in the sector, with little change over the last year.
  • Poverty levels have risen since the wildfires, but some improvements are emerging. The share of households in poverty has declined modestly over the past year but remains markedly above pre-fire levels, and most households are still poorer than before. The share of households above but near the poverty threshold has increased the most after the wildfires, but it has also been on a downward trajectory in the last few months.
  • Unmet needs have declined slightly, but assistance has fallen substantially. Financial assistance remains the most frequently reported need. FEMA assistance has been cut in half over the last year and a half. Other government assistance has also declined, and only half as many people now receive help from community organizations compared with the start of 2025. About half of fire-affected people received no assistance of any kind in May 2026, almost double the share a year earlier. Some of this decline may reflect households regaining stability, but the scale suggests assistance has likely also fallen for households who still need it.

With support from the , ÌÇÐÄÊÓÆµERO will continue to monitor and analyze the progress of the recovery in its fourth year.

University of Hawaiʻi at ²ÑÄå²Ô´Ç²¹ researchers are working to determine whether Hawaiʻi-grown eucalyptus could become a reliable source of lumber for construction, helping reduce the state’s reliance on imported building materials while supporting healthier forests.

The project, led by Jun Wang, an assistant professor in the , received a $300,000 USDA Forest Service Wood Innovation Grant to establish the engineering standards needed for eucalyptus to be used in structural applications.

Establishing construction possibilities

Assistant Professor Jun Wang’s research team

Although Hawaiʻi has more than 34,000 acres of managed eucalyptus plantations, the wood is rarely used in construction because engineers and builders lack the design data needed to certify it for structural use. If successful, the research could create new opportunities for Hawaiʻi’s forestry and wood products industries while reducing shipping costs, supply chain risks and carbon emissions associated with importing lumber. Researchers also say putting more eucalyptus to use could encourage better forest management by reducing excess wood that can contribute to wildfire fuel.

The research team will work with state agencies, forest landowners and industry partners to harvest trees, produce lumber and test its strength and durability. The findings will help establish engineering design values needed for commercial construction and could lay the groundwork for future engineered wood products made in Hawaiʻi.

“Our goal is to determine whether a resource that’s already growing in Hawaiʻi can safely be used to build the homes, schools and infrastructure our communities need,” Wang said. “If we can provide the engineering data the construction industry needs, we can help create a more resilient local building supply while giving our students the opportunity to solve real challenges facing Hawaiʻi.”

Student involvement

The research also will benefit students. Wang’s team received an $8,000 American Society for Engineering Education grant to incorporate Hawaiʻi-grown eucalyptus into civil engineering courses. The new curriculum will give students hands-on experience evaluating sustainable building materials by comparing locally grown eucalyptus with conventional construction materials.

Students will examine factors such as structural performance, carbon emissions and local sourcing while participating in research that addresses Hawaiʻi’s unique environmental and construction challenges. Many members of the research team are ÌÇÐÄÊÓÆµ students from Hawaiʻi who are helping develop solutions that could benefit the state’s future infrastructure and economy.

In an effort to help the estimated 93,000 people exposed to jet-fuel-contaminated drinking water, the , facilitated by the University of Hawaiʻi, held a training event for healthcare professionals with guidance on caring for patients using findings from recent research.

tap water

In July 2026, and partnering with the Center for Occupational and Environmental Health at University of California, Berkeley, the registry provided nearly 200 healthcare professionals with the most up-to-date guidance when caring for patients who were exposed to jet fuel in November 2021, including emerging recommendations for clinical evaluation, monitoring, treatment considerations and patient support. .

Drawing from a recent National Academies of Sciences, Engineering, and Medicine report, “Clinical Follow-up and Care for Those Impacted by the JP-5 Releases at Red Hill,” the registry’s webinar reached a national audience of participants.

“Broadly sharing the registry as the best method for collecting long-term health information is critical given the global dispersion of exposed military families that have relocated since the crisis occurred,” said Rosana “Sanie” Weldon, director of the Red Hill Registry.

Advancing care through provider education

The registry offers educational opportunities for both healthcare professionals and community members. In March, Seiji Yamada, a family medicine physician, director of medical student education, and faculty member at the , presented the registry’s first continuing education session for healthcare professionals during “Grand Rounds,” hosted virtually by Pali Momi Medical Center.

“Our website houses resources, such as fact sheets and reports, that Red Hill community members can utilize for their own health advocacy, including a letter to clinicians documenting the exposure,” said Weldon.

One of those resources is a examining the health effects of exposure to unburned kerosene-based jet fuels and other kerosene-based products in Environmental Health. Led by Veronica Carvajal, junior specialist at the and scientific coordinator for the Thompson School Registry Hub, the review is the first to focus on exposure to unburned jet fuel specifically and continues to inform the ongoing work of the registry.

“The Red Hill Registry offers an important opportunity for both community members and researchers to help close this gap, an increasingly urgent issue given the multitude of jet fuel contamination events that have occurred,” said Carvajal.

Since the 2021 fuel spill at Red Hill, additional spills have occurred across the country, underscoring the need to better understand the long-term health effects of pre-combustion jet fuel.

The registry’s next continuing education opportunity will be at the Western Occupational Health Conference hosted at the ʻAlohilani Resort in September, where registry staff will be keynote speakers.

Assistant Professor Liuwan Zhu (left) and Assistant Professor Zepeng Li (right) will lead two ÌÇÐÄÊÓÆµ research projects selected for the U.S. Department of Energy’s inaugural Genesis Mission, a national initiative using artificial intelligence to accelerate scientific discovery

Two University of Hawaiʻi at Mānoa research projects have been selected for the inaugural , placing ÌÇÐÄÊÓÆµâ€™s flagship research campus among a select group of universities and research institutions nationwide using artificial intelligence (AI) to accelerate scientific breakthroughs.

In the , the DOE said the projects were selected to develop and demonstrate AI-enabled tools and workflows designed to accelerate breakthroughs in energy, science and national security. Each project is eligible for Phase I awards of $500,000–$750,000 over nine months, providing investigators with the opportunity to develop innovative AI-driven research while positioning them to compete for future Phase II awards of up to $15 million.

“The selection of not one, but two ÌÇÐÄÊÓÆµ Mānoa projects for this highly competitive DOE mission reflects the strength of the ÌÇÐÄÊÓÆµ research community and the creativity of our faculty in pursuing solutions to some of the most complex challenges facing society,” said ÌÇÐÄÊÓÆµ Interim Vice President for Research and Innovation Chad B. Walton. “At ÌÇÐÄÊÓÆµ, we are committed to fostering an environment where bold ideas, interdisciplinary collaboration and emerging technologies can come together to create meaningful impact not only in Hawaiʻi, but across the nation, and around the world.”

The two ÌÇÐÄÊÓÆµ Mānoa projects selected are led by researchers in the and the .

AI security for critical infrastructure

One project, led by Assistant Professor Liuwan Zhu from the Department of Electrical and Computer Engineering, focuses on improving the security and reliability of AI systems used in critical infrastructure. The project, called STRATOS (Security and Trust Runtime Architecture for Time-critical Operational Science), will develop an AI security platform designed to detect and respond to cyber threats targeting AI systems used in real-time operations, such as electrical grid management and forecasting.

The research team will test the technology using a dual-site platform that includes the ÌÇÐÄÊÓÆµ Mānoa campus microgrid and real-time computing systems at Argonne National Laboratory. The project includes collaborators from Old Dominion University and Argonne National Laboratory.

AI advances the search for extremely rare decay processes

The second project, led by Professor Zepeng Li from the Department of Physics and Astronomy, will develop an AI foundation model to support searches for neutrinoless double beta decay, one of the most important unanswered questions in nuclear and particle physics. Neutrinoless double beta decay is an extremely rare nuclear process that, if observed, could help scientists better understand the nature of neutrinos, the mysterious “ghost particles” that are abundant in the universe and are constantly passing through us without interacting. In particular, this rare decay process could tell us whether the neutrino is its own anti-particle.

Researchers around the world are searching for this phenomenon using different types of detectors, but each experiment typically relies on its own specialized software and analysis methods. Li’s project aims to create a shared AI framework that can learn from data across multiple detector technologies, helping researchers identify patterns, analyze results and improve collaboration among experiments studying this rare event. The project will develop a unified AI framework that streamlines data analysis across the diverse detector technologies used in neutrinoless double-beta decay experiments, accelerating the search for this rare process.

The Genesis Mission brings together DOE laboratories and universities to combine advanced AI, high-performance computing and scientific expertise. ÌÇÐÄÊÓÆµ Mānoa was among 168 universities selected for the first round of Genesis Mission projects, which included a total of 278 research efforts involving more than 340 institutions across the country. Through these projects, ÌÇÐÄÊÓÆµ researchers will contribute to emerging applications of AI in fundamental physics, energy systems and national security, while strengthening Hawaiʻi’s role in cutting-edge scientific research.

Three years after the 2023 Maui wildfires, residents are showing meaningful signs of recovery—but persistent food insecurity, housing instability, health concerns and weakening social support continue to place many families at risk. That is the central finding of a new community report released July 27 from the (MauiWES), led by researchers at the University of Hawaiʻi.

The report, “,” follows many of the same adults and children over time, allowing researchers to examine how their health and living conditions have changed since the disaster. The findings show that recovery is underway, but that progress remains uneven across Maui families.

MauiWES has conducted more than 4,000 appointments and screenings to more than 2,500 participants, providing residents with mental health assessments, blood pressure checks, lung function testing, blood testing, social needs screening, health information and referrals.

Key findings

  • Employment among returning adults increased from 62.0% to 80.9%.
  • Health insurance coverage increased from 85.1% to 90.5%.
  • Participants living in temporary housing declined from 40.6% to 34.4%, while those who felt secure in their housing increased from 72.2% to 79.6%.
  • Food insecurity remained widespread, affecting 44.9% of returning adults. The most severe level of food insecurity remained essentially unchanged at approximately 23%.
  • High social support declined from 62.3% to 53.7%, suggesting growing recovery fatigue and strain on families and community networks.
  • Nearly one in two adults continued to report depressive symptoms, approximately one in four screened with moderate-to-severe anxiety and nearly one in three reported post-traumatic stress symptoms.

“These findings show that Maui’s recovery is moving forward, with real progress in employment, insurance coverage and housing stability,” said Ruben Juarez, co-director of MauiWES and –HMSA Distinguished Professor of Health Economics. “The opportunity now is to build on that progress by connecting housing, food, healthcare and social support so that every family has the foundation needed to recover and thrive.”

The report identifies four closely connected foundations of long-term health recovery:

  • Food and income security
  • Stable and secure housing
  • Access to healthcare and follow-up
  • Strong family and community support

Researchers found that residents facing food insecurity, housing insecurity or limited social support consistently experienced greater emotional distress. For example, half of adults who felt insecure in their housing reported moderate-to-severe post-traumatic stress symptoms, compared with about one-quarter of those who felt secure.

“The progress is real, and it should be recognized,” said Alika K. Maunakea, MauiWES co-director and professor. “But the biological, emotional and social consequences of a disaster do not disappear on the same timeline as debris removal or reconstruction. Long-term recovery requires continued health monitoring, early intervention and trusted pathways to care.”

Children remain a priority

The report highlights mixed findings among children and adolescents. Overall anxiety and mild-to-moderate depression declined, but severe depressive symptoms increased from 11.8% to 15.1%, and severe post-traumatic stress symptoms increased.

Children’s lung function screening results improved but remained concerning, according to researchers. Stage 1-range blood-pressure readings and obesity also increased, reinforcing the importance of continued pediatric screening, school-based mental-health support and family-centered services.

“Children may appear resilient while still carrying significant emotional and physical effects beneath the surface,” said Christopher Knightsbridge, a MauiWES mental-health therapist based in Lahaina. “Supporting children means supporting the entire family—including their housing, food security, daily routines and access to trusted care.”

From screening to sustained care

The report calls for Maui’s recovery to move from separate emergency programs toward a coordinated health-recovery system connecting healthcare, behavioral health, housing assistance, food programs, schools, insurance enrollment and trusted community organizations.

“Screening cannot end with a result on paper,” Juarez said. “Every concerning result should become a supported pathway to diagnosis, treatment and follow-up. Families should not be left to navigate a complicated recovery system on their own.”

MauiWES is a community-based partnership involving ÌÇÐÄÊÓÆµ researchers, local healthcare providers, grassroots organizations and recovery partners across Maui.

A University of Hawaiʻi at Mānoa physicist is part of an international team behind a new approach to studying some of the universe’s most mysterious particles&@8212;using mountains instead of ice.

A paper published July 15 in outlines the scientific potential of the (TAMBO), a proposed neutrino observatory that would use a deep valley in the Peruvian Andes to detect some of the highest-energy neutrinos ever observed.

Neutrinos are tiny, nearly massless particles created during some of the universe’s most powerful events, such as exploding stars and supermassive black holes. Because they rarely interact with matter, they can travel across the universe almost unchanged, carrying clues about where they came from. That same property, however, also makes them extremely difficult to detect.

Neutrinos, rocks, cascades of particles

An Earth-skimming tau neutrino undergoes a charged-current interaction within the left canyon
face, producing a tau lepton. The tau lepton emerges from the canyon face into the valley
and decays, creating an air shower. This air shower is detected by TAMBO, deployed on the
opposite canyon face. (Image credit: TAMBO collaboration)

Unlike the IceCube Neutrino Observatory in Antarctica, which detects neutrinos using sensors embedded deep in glacial ice, TAMBO would use the natural landscape of a mountain valley. When a rare, high-energy tau neutrino passes through Earth’s crust and interacts with rock, it can produce a particle that escapes into the valley and creates a cascade of particles in the air. Thousands of detectors placed on the opposite side of the valley would capture that signal.

By focusing on high-energy tau neutrinos (one of three types of neutrinos), researchers expect TAMBO to identify cosmic neutrinos with far less interference from particles produced in Earth’s atmosphere. That could help scientists pinpoint the powerful cosmic objects that generate them and provide new opportunities to test fundamental laws of physics.

ÌÇÐÄÊÓÆµ Mānoa Assistant Professor Peter Lewis is a member of the international TAMBO collaboration, which includes researchers from 26 institutions across nine countries. TAMBO was originally proposed by ÌÇÐÄÊÓÆµ alumnus Andres Romero-Wolf, who until recently served as the project’s manager.

“Neutrinos are exceedingly weird and challenging to detect, but we need to study them to understand the universe,” Lewis said. “TAMBO will fill a critical gap in our understanding of neutrinos. It will also continue a very long and rich tradition of neutrino detection leadership at ÌÇÐÄÊÓÆµ Mānoa. TAMBO will give our students a unique opportunity to collaborate with an international collaboration on fast-paced, innovative work in advanced detector design and neutrino physics.”

Researchers are evaluating the Colca Valley in Peru as a potential site for the observatory. Construction of TAMBITO, a prototype for the project, is already underway, with the full TAMBO observatory expected to be completed in 2028. The collaboration is also working with local communities and social scientists to help ensure the project is developed responsibly while supporting education and research opportunities in the region.

Alika K. Maunakea, professor at the ÌÇÐÄÊÓÆµ ²ÑÄå²Ô´Ç²¹ John A. Burns School of Medicine, is a senior author of a study that found that certain gut bacteria are associated with the pace of biological aging. The research adds to growing evidence that the gut microbiome may play an important role in long-term health and healthy aging.

Researchers at the University of Hawaiʻi at Mānoa have found that certain gut bacteria are linked to how quickly the body ages, providing new insight into the connection between the gut, health and longevity.

The findings, , found that differences in gut bacteria explained about 15% of the differences in how quickly participants’ bodies were biologically aging. The work provides evidence that gut microbiome carries meaningful biological information related to how quickly the body ages at the molecular level.

“This study advances our understanding of the relationship between the gut microbiome and biological aging,” said senior author Alika K. Maunakea of the ÌÇÐÄÊÓÆµ Mānoa . “We found that microbial patterns in the gut were significantly associated with molecular measures of aging, even independent of chronological age. These findings open important new directions for understanding how modifiable biological systems influence long-term health trajectories and longevity.”

Tracking the gut-body connection

The research analyzed stool and blood samples from 123 participants representing a broad adult age range. The team compared the types of bacteria found in participants’ guts with biological markers in their blood that estimate how quickly their bodies are aging. Unlike chronological age, which measures the number of years a person has lived, biological aging biomarkers attempt to capture how rapidly the body is aging physiologically.

The investigators observed that gut microbial composition was specifically associated with DunedinPACE, a next-generation biomarker that estimates the pace of biological aging. Several types of bacteria demonstrated particularly strong associations with aging trajectories. Among the findings, Bifidobacterium adolescentis emerged as one of the strongest microbial signatures associated with slower biological aging, while Succinivibrio dextrinosolvens showed one of the strongest associations with accelerated aging.

Lead author Braden P. Kunihiro said the findings highlight the growing scientific importance of the gut microbiome in precision health research.

“The gut microbiome is highly responsive to lifestyle, diet, environment and other everyday exposures,” Kunihiro said. “Our findings suggest that the microbiome may reflect important aspects of biological resilience and aging in ways that could eventually help inform future wellness and healthy aging strategies.”

The study also included a group of Native Hawaiian and Pacific Islander participants, populations historically underrepresented in aging and microbiome research. Co-author Ruben Juarez noted that the work may help researchers better understand how environmental and social factors become biologically embedded over time.

“The microbiome exists at the intersection of behavior, environment and human biology,” Juarez said. “Studies like this help illuminate potential pathways through which lived experiences and social factors influence long-term health outcomes.”

The researchers emphasize that the study found a connection between gut bacteria and biological aging, but it does not prove that one causes the other. More research is needed to determine whether changing the gut microbiome can affect how the body ages.

“This is an important early step toward understanding the gut microbiome’s relationship with healthy aging,” Maunakea said. “Future research will help clarify the mechanisms involved and whether these microbial signatures may eventually contribute to precision approaches for promoting long-term health and wellness.”

Human activities are fundamentally altering the chemical makeup of local coral reefs, according to a study led by the University of Hawaiʻi at Mānoa and published in . The research team discovered that 25 contaminants from agricultural, industrial and pharmaceutical sources accumulated in the soft tissues of coral around Maui. Additionally, in areas impacted by human activities, the energy and nutrient availability within the coral’s tissue decreases, making them significantly less resilient to environmental stressors such as warmer or acidic waters.

“Our findings suggest that monitoring the pool of chemicals within the coral tissues, called metabolomes, can serve as a powerful tool for tracking the hidden impacts of anthropogenic [human induced] disturbance on marine life,” said Zach Quinlan, lead author and research biologist at the (HIMB) in the ÌÇÐÄÊÓÆµ Mānoa .

Quinlan and an international team of researchers tested the metabolomes of 380 lobe corals (Porites lobata) and rice corals (Montipora capitata) from 16 sites off west and south Maui. They found that human activities both within the adjacent watershed and in the marine ecosystem altered the composition of the corals’ metabolomes. In areas with more ecosystem disturbance, there was increased accumulation of contaminants and a decrease of nutrient and energy reserves in the coral tissues.

“It was extremely surprising that the metabolomes of both coral species had almost identical trends,” said Quinlan. “These corals have very different life strategies, and we wouldnʻt normally expect them to accumulate contaminants the same or even necessarily respond the same to disturbances.”

Clues from 2016 bleaching event

Using historical trends in coral from five of the sites they sampled, the team found that sites that had the most severe declines in coral cover after the 2016 bleaching event are the sites with the most impacted metabolomes. At more impacted sites, nitrogen and energy reserves were reduced, while stress chemicals were enriched.

The research team proposed two potential mechanisms by which human activities and contamination of marine environments lead to decreased coral resilience: 1) accumulation of anthropogenic molecules such as pharmaceuticals and industrial byproducts, and 2) increased pressure from anthropogenic activities requires coral to utilize portions of their nitrogen and energetic reserves.

Tracing contaminants through the ecosystem

The researchers propose that monitoring the metabolomes of coral or other coastal seafloor species can be used as a powerful tool to track human impacts on natural ecosystems.

“Beyond the implications for coral health and resilience, this study demonstrates how many anthropogenic contaminants are escaping into marine ecosystems,” Megan Donahue, senior author on the paper and HIMB director. “We see increasing evidence that anthropogenic contaminants have broad cumulative impacts that can undermine the resilience of coastal ecosystems.”

Looking ahead, Quinlan and team are searching for ways to enrich coral tissue nitrogen and energy reserves in controlled experiments to determine whether those increases lead to more resilient corals.

Additional co-authors include researchers from Woods Hole Oceanographic Institution, University of Newcastle (Australia), University of New South Wales (Australia), Bio21 Molecular Science and Biotechnology Institute (Australia), The Nature Conservancy, University of California Merced, Princeton University and James Cook University (Australia).

For many adults at risk for Type 2 diabetes, knowing where to begin can be one of the biggest obstacles to prevention. A new study from the Healthy Hawaiʻi Evaluation Team (HHET) at the University of Hawaiʻi at ²ÑÄå²Ô´Ç²¹ and the Hawaiʻi State Department of Health (HDOH) found that a statewide media campaign helped encourage more adults to take that first step by enrolling in the National Diabetes Prevention Program (DPP).

The study, published in , evaluated the statewide Beat Diabetes campaign, a HDOH initiative that ran from July through October 2024 across different media. The campaign encouraged adults at risk for Type 2 diabetes to enroll in the evidence-based DPP, which can reduce the risk of developing the disease by up to 58%. A follow-up survey was conducted from October through December 2024.

The Beat Diabetes campaign targeted Native Hawaiian, Other Pacific Islander and Filipino adults—communities with higher prediabetes rates—using messages tested in focus groups reflecting those populations. Participants responded most strongly to messages urging immediate action, shaping the campaign’s call to enroll in a DPP.

Evaluating campaign impact

To evaluate the campaign’s effectiveness, researchers from HHET, housed in the ÌÇÐÄÊÓÆµ ²ÑÄå²Ô´Ç²¹ , collaborated with HDOH’s (CDPHPD) to survey 860 Hawaiʻi residents ages 35 to 64 who reported at least one diabetes risk factor.

“Our programs leverage HHET’s expertise in chronic disease prevention and health communications. We’re excited to use these findings to improve our support for people at risk for diabetes,” said Blythe Nett of CDPHPD.

Among survey respondents, 40% reported seeing or hearing the Beat Diabetes campaign. Those who recalled the campaign were more likely to join the DPP than those who did not.

“Exposure to the campaign may increase one’s likelihood to join a DPP; however, it’s important to also address other structural and logistical barriers that can get in the way of actual enrollment into a DPP,” said Kara Saiki, the study’s lead author and HHET researcher.

The findings suggest that culturally relevant public health campaigns can encourage people to take the first step toward diabetes prevention. Researchers say future efforts may be even more effective by pairing motivational messaging with strategies that reduce barriers such as time, cost and access to prevention programs.

Researchers build new hybrid aquaponics, vertical farming system /news/2026/07/17/vertical-farms/ Fri, 17 Jul 2026 23:16:26 +0000 /news/?p=237576 ÌÇÐÄÊÓÆµ ²ÑÄå²Ô´Ç²¹ researchers are developing a vertical farming system that uses advanced aquaponics and nanobubble technology.

Vertical farming is ideal for Hawaiʻi, where agricultural land is limited.

In a state where land is expensive, and the tropical heat can be a hurdle for certain crops, researchers at the University of Hawaiʻi at ²ÑÄå²Ô´Ç²¹â€™s (CTAHR) are looking up.

Kyle Marcelino, a PhD graduate from the Department of Molecular Biosciences and Bioengineering (MBBE) at CTAHR, conducted this research under the mentorship of Professor Samir Kumar Khanal, principal investigator, and Surendra K.C., PhD, a research scholar on Professor Khanal’s team. Together, the team is exploring new ways to strengthen local agriculture through a hybrid controlled environment system. By combining vertical farming with advanced aquaponics, they are developing a sustainable path for more commercial food production in the islands.

The tech behind the tower: Nano bubbles

At the heart of this project is the integration of nanobubble technology. Traditional aquaponic systems can struggle to maintain enough dissolved oxygen for healthy plant roots and beneficial bacteria. This system injects pure oxygen directly into the water using nanobubble technology.

CTAHR researchers are working with nanobubble technology to naturally stimulate the growth of lettuce and leafy green vegetables in growing towers.

“One of the most important parts of aquaponics is trying to maintain dissolved oxygen,” Marcelino said. This boost in oxygen serves several critical functions:

  • It reduces root decay or root rot caused by harmful bacteria.
  • It supports the natural bacteria that convert fish waste into plant-available nutrients.
  • It encourages bacteria to break down organic solids, preventing the buildup of sludge that can choke a system.

A system built for Hawaiʻi

With limited agricultural land available in Hawaiʻi, growing vertically offers an efficient alternative. The hybrid greenhouse system uses technology to regulate temperature, UV exposure and water quality.

Vertical farming with advanced aquaponics can be a sustainable path for commercial food production in the islands.

While the system is ideal for leafy greens, researchers are expanding their horizons to include high-value crops like strawberries that struggle in Hawaiʻi’s humidity. It can also be used for radishes and other highly nutritious root vegetables.

The ultimate goal is to help move the technology from research to commercial use, giving local farmers another tool to grow fresh food more efficiently.

“The whole big goal is to try to eventually build this controlled environment system where farmers can control temperature, water quality, and oxygen levels to grow high-value crops and feed communities,” said Marcelino.

This research is supported by the CTAHR CARES Initiative and the Mamoru and Aiko Takitani Foundation, and conducted under the leadership of Professor Khanal and K.C.

Could liquids help people breathe?

Researchers at ÌÇÐÄÊÓÆµ ²ÑÄå²Ô´Ç²¹ study a droplet of oxygen-carrying liquid suspended in water to better understand how the lungs’ natural surfactant behaves. The research could help advance future liquid breathing technologies.

For decades, scientists have studied whether oxygen-carrying liquids could help people breathe when their lungs are too damaged or underdeveloped to function normally. They have assumed those liquids could replace the lung’s natural surfactant—an ultrathin film that coats the tiny air sacs inside the lungs and prevents them from collapsing during breathing. Research from the University of Hawaiʻi at ²ÑÄå²Ô´Ç²¹ suggests that assumption may be incorrect.

A new three-year, $491,121 National Science Foundation (NSF) award will enable Professor Yi Zuo and his team to investigate one of the most fundamental unanswered questions in lung biophysics while developing a new generation of experimental tools that could advance biomedical engineering, materials science and future liquid breathing technologies.

“The oxygen-carrying liquid does not simply replace the lung’s natural surfactant,” said Zuo from the and the . “Instead, the two appear to work together at the interface between two liquids. Understanding how that interface behaves is essential if we want to improve future liquid ventilation technologies.”

A century-old problem with new implications

This is an AI-generated image provided by Professor Yi Zuo.

Scientists have studied the pulmonary surfactant for more than 70 years to understand how it works when we breathe air. Much less is known about how it behaves when the lungs are filled with oxygen-rich liquids.

Liquid ventilation, in which oxygen-carrying perfluorocarbon liquids (synthetic liquids that carry large amounts of oxygen) partially or completely replace air in the lungs, has long been investigated as a potential treatment for premature infants and patients suffering from severe respiratory failure. Researchers have also envisioned future applications in emergency medicine, deep-sea diving and human space exploration. However, much remains unknown about the basic mechanics of how these liquids interact inside the lungs.

Inventing a new scientific tool

A major objective of the project is developing a new experimental platform capable of studying molecular behavior at liquid-liquid interfaces. Current techniques were originally designed nearly a century ago to investigate films on water exposed to air. Those methods work well for traditional surface science but cannot adequately study the interface between two liquids.

Building upon technology invented in Zuo’s laboratory, the team is developing a small device that lets scientists watch how molecules gather and interact where two different liquids meet.

“This project is really about developing a new way of studying one of nature’s most important interfaces,” Zuo said. “Once we have the technology, it can be applied far beyond lung biology.”

Impact beyond medicine

Liquid-liquid interfaces play essential roles in biological systems, advanced manufacturing, biotechnology, drug delivery, energy technologies, food science and environmental engineering. The new instrumentation developed through this NSF project is expected to provide researchers with a versatile platform for investigating molecular self-assembly in many different applications.

ÌÇÐÄÊÓÆµ Maui High Performance Computing Center.

Reliable operation of data centers has become essential to nearly all sectors of modern society, including healthcare, education, government services, power grid operation, banking, defense and disaster relief. New research published in and led by University of Hawaiʻi at Mānoa revealed that future climate conditions may reduce the availability of one of the cheapest and most energy-efficient approaches to cooling data centers.

The research team, led by Christina Karamperidou, atmospheric sciences professor in the ÌÇÐÄÊÓÆµ Mānoa , assessed historical and projected temperatures and humidity levels around the world and compared them to the conditions required for “direct air free cooling,” wherein naturally cold outside air is brought in to cool a building or equipment.

data center
ÌÇÐÄÊÓÆµ ITS data center.

A confluence of factors presents a substantial societal challenge: with the artificial intelligence (AI) boom, the demand for data centers is increasing, just as climate conditions are limiting an efficient approach to cooling these facilities.

“We found that periods of time when temperature and humidity exceed recommended operating thresholds for direct air free cooling are becoming more frequent and lasting longer in many regions,” said Karamperidou. “This will reduce the availability of air free cooling for a growing number of data centers globally.”

Looking to the past and future

Karamperidou and co-authors combined high-resolution hourly weather observations with climate model simulations and a global database of data center locations. This allowed them to evaluate how often environmental conditions exceeded recommended operating limits for direct air free cooling, both historically and in future climate scenarios. By analyzing global datasets, they were able to identify large-scale patterns and trends that would not be visible from studies focused on individual facilities.

The researchers found over the past 45 years, the number of hours characterized by high temperature and humidity conditions that limit direct air cooling has increased significantly, particularly across the tropics and the southeastern U.S. A site- and market-level analysis further showed that the share of data centers exposed to conditions that limit air free cooling availability for at least one quarter of the year is rising. Projections through mid-century indicate continued expansion of these constraints with sustained warming and increasing humidity.

Worst-day conditions

One of their key findings is that the largest changes are not always seen in average conditions. In several regions, worst-day conditions are intensifying more rapidly than average conditions, indicating that environmental stress is becoming increasingly concentrated in rare but consequential events.

“From an operational perspective, those worst-day conditions often drive contingency planning, system overrides, redundancy requirements, and reliability decisions,” Karamperidou shared. “This suggests that infrastructure planning may need to account not only for average environmental conditions but also for how the most stressful days are changing over time.”

This work was developed in collaboration with researchers working on cyberinfrastructure and next-generation cooling technologies, including partners through the , where ÌÇÐÄÊÓÆµ is a key partner institution.

Emily Marron

A University of Hawaiʻi at Mānoa faculty member has received a $660,000 National Science Foundation (NSF) Faculty Early Career Development (CAREER) Award to study how fuel contamination can affect drinking water during the treatment process.

Emily Marron, an assistant specialist in the and cooperating graduate faculty and instructor in the , will lead the five-year project, which runs through June 2031.

tap water

The research focuses on what happens when chlorine—commonly used to disinfect drinking water—reacts with fuel that has entered water supplies after spills or leaks. While chlorine is regularly added to drinking water systems to help control bacterial growth and eliminate harmful pathogens, it can also react with fuel-related chemicals to create unintended byproducts that may pose health risks.

Marron and her research team will use advanced analytical chemistry techniques, such as high-resolution mass spectrometry, to identify the compounds formed during these reactions, measure how quickly they develop and better understand how fuel changes over time affect water treatment. The findings could improve how contaminated drinking water systems are evaluated and treated following fuel releases.

Clean drinking water, complex contamination

“Clean drinking water is something every community depends on,” Marron said. “I hope this research gives scientists and water professionals better tools to understand complex contamination events and make informed decisions that help protect public health.”

The project could also provide new insight into the types of chemical compounds people might have been exposed to in drinking water following the Red Hill fuel contamination in 2021. Rather than recreating the specific conditions of the Red Hill incident, the research will use controlled laboratory experiments to build a scientific framework for studying fuel-contaminated water. The research could also help inform public health decisions and improve response strategies during contamination events.

In addition to the research, the project includes education and community outreach. Marron will develop an undergraduate teaching module in partnership with local water professionals, including the Honolulu Board of Water Supply, to give students hands-on learning opportunities in environmental chemistry and drinking water treatment.

The project will also establish a community-centered laboratory that expands access to low-cost drinking water testing. The effort is designed to help residents better understand water quality, environmental chemistry and the science behind keeping drinking water safe.

The NSF CAREER program is among the foundation’s most notable awards for early-career faculty, recognizing researchers who integrate innovative research with education and community engagement.

Ernest Bethe IV

University of Hawaiʻi at Mānoa graduate candidate Ernest Bethe IV has been awarded a Fulbright U.S. Student Program scholarship for the 2026–27 academic year. After completing his master of degree from the this August, Bethe will embark on a 10-month research initiative in Ecuador. Based in Puerto Ayora—the fastest-growing town in the Galápagos Islands—he will investigate how overlooked urban spaces can be leveraged for ecological resilience (ability of ecosystems to adapt to environmental change).

Rethinking ‘informal’ green spaces

As tourism and development exert heavy pressure on the limited land resources of island ecosystems, Bethe’s research will look at cost-effective frameworks for sustainable growth. His project will focus on “informal green spaces”—such as vacant lots, roadside vegetation and unmanaged patches of land—and will examine their potential to:

  • Support vital habitats for native bird species.
  • Reduce localized flooding and mitigate the urban heat island effect (where built-up areas trap more heat than natural surroundings).
  • Develop sustainable growth that balances tourism and development needs with limited land resources.

In Ecuador, Bethe will be hosted by the Charles Darwin Foundation, with a secondary academic affiliation at the Pontificia Universidad Católica del Ecuador.

A model for island cities

The upcoming fieldwork builds directly on Bethe’s capstone project at ÌÇÐÄÊÓÆµ Mānoa, which focused on ecological urban design. A core outcome of his Fulbright project will be a bilingual planning toolkit designed for local officials and community stakeholders in Ecuador. However, the implications of his work extend far beyond the Galápagos.

“Islands everywhere are dealing with the same issue: how do you grow without paving over the very thing that makes the place worth living in?” said Bethe. “If we can highlight how the green spaces we usually overlook are actually cooling our streets, soaking up stormwater, and giving our native birds somewhere to land, that’s a low-cost tool that any island city—including Honolulu—can put to work.”

Ashok Das, urban and regional planning professor and department chair, said, “Ernest’s winning the Fulbright award is a matter of great pride for our department, college and university. It is a testimony to his ability to apply multiple concepts in creative ways to advance a core mission of urban planning—sustainable development.”

“It also underscores his commitment to making vulnerable island communities more resilient. Having grown up in Indonesia and studied in Hawaiʻi have definitely shaped his worldview. He is multilingual, loves experiencing new cultures and thrives in multicultural settings. He will be a wonderful ambassador of the Fulbright program and ÌÇÐÄÊÓÆµ Mānoa.”

The is administered by the U.S. Department of State and is one of the nation’s most prestigious international exchange initiatives. It aims to expand perspectives through academic and cultural exchange in partnership with more than 140 countries worldwide.

Unexpectedly low calf numbers within the spinner dolphin population off Hawaiʻi Island were revealed in a study led by scientists with the (MMRP) at the University of Hawaiʻi at Mānoa along with national and international collaborators. Their research, published in , determined that calves make up only about 9% of the population, a stark contrast to the 17% expected in a healthy, stable population, raising urgent concerns about the long-term survival of this isolated population.

Viewing spinner dolphins is an attraction of the tourism industry in Hawaiʻi, however, those activities put pressure on the marine species. Previous research has shown that this population of dolphins experiences the highest levels of disturbance exposure recorded for dolphins worldwide.

“The evidence suggests chronic human disturbance—especially tourism and recreational-related interactions during critical dolphin resting periods—as a likely contributing factor affecting reproductive success and calf survival,” said lead author Fabien Vivier, who was a doctoral student at the in the ÌÇÐÄÊÓÆµ Mānoa at the time of this work. “The findings support stronger conservation actions, such as time-area closures for human activities, alongside continued long-term monitoring—actions that have long been called for.”

Drone surveys reveal population trends

To reach these conclusions, scientists utilized drone photography to measure the body length of free-swimming dolphins. By combining these aerial measurements with age-length data from stranded spinner dolphins collected by Kristi West, study co-author and researcher with the ÌÇÐÄÊÓÆµ Health and Stranding Lab at the ÌÇÐÄÊÓÆµ Mānoa , the team created the first age-length growth curve for this specific population. This allowed them to accurately categorize individuals into calves (under 2 years), juveniles (2–9 years), and adults (over 9 years).

Age structure is an early indicator of population health and long-term viability. The documented low proportion of calves suggests the spinner dolphin population off Hawaiʻi Island may not be replacing itself fast enough, which could lead to future population decline.

Highly valuable and vulnerable population

In Hawaiʻi, spinner dolphins are culturally, ecologically and economically important. Research from 2013 estimated that each individual dolphin is valued at more than $3.3 million over its lifetime and collectively, dolphin tourism generates more than $100 million annually for the state’s economy.

With spinner dolphins following a predictable daily cycle—foraging offshore at night and returning to shallow coastal bays during the day to rest and socialize—they are especially vulnerable to tourism activities in these nearshore habitats.

“This study provides one of the first population-level demographic signals suggesting those long-term disturbances may now be affecting reproduction and calf survival,” said Professor Lars Bejder, co-author on the study and MMRP director.

A call for stronger protections

While a 2021 federal rule requires people and vessels to remain at least 50 yards away from the dolphins, experts from the U.S. Marine Mammal Commission and the Pacific Scientific Review Group have argued that this measure is insufficient. The study authors are calling for stronger conservation actions, specifically time-area closures that would restrict human access to critical resting bays during the day.

“Understanding these impacts is critical for protecting an isolated local population before declines become irreversible,” Randall Wells, study co-author and director of Brookfield Zoo Chicago’s . “We hope this work provides the science-based evidence needed to develop effective protections for spinner dolphins while helping balance marine tourism, cultural stewardship, and long-term ecosystem health in Hawaiʻi.”

Future research and monitoring will depend on available funding, with scientists aiming to track long-term changes in age structure, reproduction, and population and further refine non-invasive drone-based methods.

Owning a home remains out of reach for many Americans, but a new analysis from the (ÌÇÐÄÊÓÆµERO) suggests the housing affordability crisis may have reached its peak.

The analysis by ÌÇÐÄÊÓÆµERO Professor Byron Gangnes finds that housing affordability deteriorated sharply across the country beginning in 2021 as home prices surged and mortgage interest rates climbed. While affordability has improved modestly over the past two years because of rising incomes, slower home price growth and slightly lower mortgage rates, many housing markets remain unaffordable—especially Honolulu.

Using a measure based on what a median-income household can reasonably afford while spending no more than 30% of its income on housing costs, the analysis found Honolulu to be among the nation’s least affordable housing markets. In 2024, the median home price in Honolulu was about twice what a median-income household could afford.

The report also found that cities once considered relatively affordable, including Charlotte, Atlanta and Dallas, have seen steep declines in affordability since the pandemic because home prices have risen much faster than incomes.

Nationally, affordability has improved since its recent low point as wage growth has helped households keep pace with housing costs and mortgage rates have eased from their highs. Even so, the report said many moderate-income families, particularly those earning below the median income, continue to face significant barriers to homeownership.

Gangnes noted that affordability can continue to improve over time as incomes rise and borrowing costs decline, but said policy changes will also be needed. The report points to strategies such as increasing housing construction, streamlining permitting, encouraging smaller homes and expanding assistance with down payments and mortgage costs to help make homeownership more attainable.

Coral reef decline driven by climate change could cost Hawaiʻi residents between $1.8 billion and $3 billion in lost reef-related activities by 2100, according to a published in Ecological Economics. The research projects these burdens will not fall equally, with lower-income and disadvantaged communities in the state facing disproportionate impacts.

The study was led by researchers at the University of Hawaiʻi at ²Ñā²Ô´Ç²¹â€™s (CTAHR), alongside scientists from the Norwegian University of Life Sciences and the University of Trento. It is one of the first studies to combine detailed ecological models with community-level economic data across the state.

“Coral reefs are foundational to life in Hawaiʻi culturally, ecologically and economically,” said lead author Ashley Lowe Mackenzie, an affiliated faculty member in the CTAHR Department of Natural Resources and Environmental Management (NREM). “Our work makes visible something that is often invisible in policy conversations by valuing real welfare losses that residents will experience as these ecosystems degrade.”

Mapping future losses

The research team used a sophisticated biophysical simulation called the Atlantis ecosystem model to project how coral cover will change across nearshore reef systems through the year 2100. They tested three different climate pathways representing low, mid-range and high global emissions scenarios.

By connecting these ecological shifts with a recreation demand model, they mapped potential economic losses for residents at a precise 1-kilometer resolution. Because the figures only capture local recreational use—such as swimming, snorkeling and diving—the authors emphasize that the $1.8 billion to $3 billion estimate represents a lower end of total economic damage.

Key findings include:

  • The earliest and most severe losses are projected along the leeward (west and south) coasts of Hawaiʻi Island and Maui.
  • Recreational losses are expected to spread northward to Oʻahu by mid-century.
  • Under a high-emissions climate scenario, nearshore reefs face a near-total collapse by 2100. Under a low-emissions scenario, some windward (east and north) coastlines show signs of partial recovery late in the century.

Disproportionate impacts on local communities

Using the U.S. Environmental Protection Agency’s environmental justice tool (EJScreen), the researchers discovered that disadvantaged communities often face higher per-person welfare losses. Traditional economic methods usually project lower monetary losses for lower-income groups, making this finding particularly striking. The data indicate that vulnerable communities are disproportionately exposed to the specific areas experiencing the steepest reef declines.

“This study puts numbers to what our communities have long understood—that losing our reefs means losing the recreational opportunities, cultural practices, and quality of life that define what it means to live in Hawaiʻi,” said Brian Neilson, administrator of the Hawaiʻi Division of Aquatic Resources. “Reef-based recreation is deeply tied to traditions of fishing, gathering, and caring for our nearshore waters.”

A call for local action

The findings connect directly to local state-led efforts such as ±á²¹·É²¹¾±ʻ¾±â€™s Holomua Marine Initiative, which works with communities and Indigenous knowledge holders to design site-specific reef management.

“The magnitude of those potential losses should be a wake-up call to take action now to protect our nearshore environment,” said senior author Kirsten L.L. Oleson, NREM professor. “Our lab’s research suggests that a lot can be accomplished through local action, particularly by reducing land-based pollution and over-harvesting.”

The research was supported by NOAA’s Ocean Acidification Program.
