The University of Central Florida unveiled a new 38-foot UCF Heath Mobile Health Clinic on Wednesday, designed to bring free, high-quality healthcare directly to communities that need it most.

The clinic also serves as a mobile classroom, preparing UCF healthcare students in programs including medicinenursingphysical therapy and speech-language pathology with hands-on experience delivering community-based care.

The clinic is the first interdisciplinary clinical care program offered by UCF’s Academic Health Sciences Center (AHSC). The center unites UCF’s colleges of Health Professions and SciencesMedicine and Nursing to create more interprofessional health education, research and patient care efforts.

“This new mobile health clinic is expanding access to healthcare in our community,” says Dr. Deborah German, who as vice president for health affairs leads the AHSC and serves as College of Medicine dean. “Our goal is simple and powerful – when healthcare providers work together, the patient receives better care.” 

The clinic is focused on low income, uninsured and underinsured populations in Orange and Osceola counties, helping patients who face transportation, mobility or financial barriers that restrict their access to healthcare.

Services include screenings for blood pressure, diabetes, cholesterol and hearing, along with chronic disease monitoring, fall-risk assessments, medication reviews, audiology services and health education.

With two private exam rooms, diagnostic equipment, and point-of-care testing capabilities, the clinic is aiming to reduce preventable conditions and improve long-term health for the Central Florida region.

“The UCF Health Mobile Health Clinic is designed to complement the incredible work being done by community health centers, federally qualified health centers and charitable clinics across Central Florida,” says Dr. Caridad Hernandez, chair of medical education at the College of Medicine, who has worked for years to make the mobile clinic a reality. “Our goal is to fill gaps and meet people where they are, working hand in hand with these organizations to amplify resources and create a seamless continuum of care.”

Training Future Health Leaders

UCF’s Academic Health Sciences Center is made up of healthcare providers, faculty, researchers, staff and students committed to improving healthcare. It is focused on educating the next generation of healthcare leaders and finding better ways to treat disease through innovation, discovery and collaboration.

The mobile clinic serves as a classroom on wheels that provides future UCF physicians, nurses, audiologists, physical therapists, occupational therapists and others with the opportunity to learn in real-world settings, side by side, as part of interprofessional teams.

“They will see firsthand how life and social circumstances impact health and care, and how collaboration strengthens outcomes,” Dr. Hernandez says. “These experiences prepare graduates who are not only clinically skilled but know how to work and communicate better in healthcare teams. That training stays with them when they go into clinics and hospitals to care for us all.” 

Mimi Allianceis a family nurse practitioner doctoral student at UCF’s College of Nursing who is providing care on the mobile health unit and conducting doctoral research on hearing screenings for seniors.

“UCF’s mobile health clinic is an incredible and innovative tool that will allow us, as a group of providers, the ability to care for patients by serving them where they are,” she says. “Ultimately, this is going to improve the health of our communities.”

Addressing a Community Need

The mobile clinic serves Florida residents who are uninsured or underinsured with income levels at or below 300% of the Federal Poverty Level. Nearly 15% of both Orange and Osceola County residents are not insured, regardless of income level. In addition, 27% of Floridians say they do not have a personal physician.

Since March, almost 500 patients have visited the clinic for blood pressure checks, hearing screenings and point-of-care testing for blood sugar levels and cholesterol. It has provided care at Four Roots Farm, Kinneret Council on Aging, Grace Medical Home, the Central Florida Fairgrounds and four Central Florida YMCA locations. UCF has also reached an agreement with Osceola County to provide care at community centers in the future.

Thanks to a grant from the Florida Department of Health, the clinic is working to improve care for the community’s diabetic patients with limited access to care.

Diabetes is a worldwide epidemic. In Florida, at least 2.17 million adults have been diagnosed with diabetes and an estimated 550,000 more are unaware they have it. The state’s diabetes rate is higher than the national average and it is getting worse – an additional 6 million adults in Florida have prediabetes.

“Many of our neighbors with diabetes have no access to healthcare. That leads to premature death, blindness, loss of limbs and kidney failure,” Dr. Hernandez says. “Through the FDOH grant, we can help provide these patients with needed care. We screen patients for diabetes, can provide prescriptions at no cost, and offer education on diet changes that will help them manage their disease.”

As one recent patient at Kinneret Council on Aging explains, “UCF helped me know what kind of food and protein I can eat to help my blood sugar not get too high or too low. Thank you so much. You are helping.”

The clinic also started a diabetic foot program after one of the Kinneret patients said she and other diabetics lacked mobility and eyesight to regularly check their feet for ulcers or blisters. Diabetes increases a patient’s risk for foot ulcers that can lead to amputation. Thanks to the foot program, UCF College of Nursing faculty and students are providing hands-on education and preventive screenings to patients, who also received their own telescoping mirrors to do regular foot checks at home.

Providing Needed Audiology Care

One of the clinic’s major health services is hearing health and the prevention of hearing loss.

“This is not just a ‘nice to have’ screening,” says Dr. Bari Hoffman,associate dean for clinical affairs at UCF’s College of Health Professions and Sciences and a certified speech pathologist who has helped lead the mobile clinic effort. “Hearing loss is linked to diabetes, cardiovascular and cardiometabolic conditions, balance, cognition and overall health. When we catch hearing loss early, we can intervene before it affects someone’s safety, memory, their social connections, or their long-term health trajectory.”

Thanks to a gift from the Edyth Bush Charitable Foundation, UCF purchased diagnostic hearing equipment to provide clinical-grade hearing assessments in the community. And though a collaboration with Central Florida Hearing Aid Recycling Programs, the mobile clinic can help connect patients with reprogrammed, refurbished hearing aids at no cost.

“This is such a meaningful addition,” Dr. Hoffman says. “Identifying hearing loss is important but ensuring people have access to hearing aids is what truly changes lives.”

The mobile clinic is also supported by gifts from the HCA Florida Healthcare/UCF Lake Nona Hospital Community Benefit Fund and The Chapman Private Foundation.

Stephanie Garris is CEO of Orlando’s Grace Medical Home, which provides high-quality, continuous care to some of Orange County’s more than 160,000 uninsured residents. Grace patients have received audiology care from the UCF mobile clinic.

“This mobile clinic is an incredible resource for our patients, offering essential services they otherwise wouldn’t have access to,” Garris says. “Through our partnership with UCF, we are expanding access to care—especially for the working poor, whose jobs often don’t include healthcare benefits.”

Expanding Efforts

Mobile clinic leaders are eager to expand services and work with additional community organizations.

Plans also include expanding the mobile clinic into an innovation hub to pilot and evaluate emerging aging-in-place and digital health technologies and integrate new diagnostic and disease prevention tools.

UCF research faculty also want to use the clinic’s services to study better ways to advance health accessibility and chronic disease management. Educators from the AHSC’s three colleges also plan to grow interdisciplinary student training across areas including audiology, nursing, medicine, physical therapy and speech language pathology.

How wildfires spread is more variable and unpredictable than Canada’s standard models assume, new research from UBC Okanagan data scientists shows. 

Ladan Tazik, lead author of a new study in Fire and UBC Okanagan doctoral student, used advanced computer vision tools to capture fire behaviour with a level of detail that wasn’t possible even a few years ago.  

Her work sheds light on the random elements of fire movement—information that could reshape how fire behaviour is modelled and forecasted in an era of worsening wildfire seasons. 

“Image processing techniques let us quantify fire behaviour in real time, including the parts that don’t follow consistent patterns,” says Tazik“By capturing the randomness in how fires spread, we can build models that better reflect reality and help improve decision-making during active fire events.” 

Tazik led the design, analysis and modelling that form the backbone of the study.  

She used the “Segment Anything Model”, a state-of-the-art AI tool, to extract fire perimeters from experimental burn videos frame by frame to study fire spread dynamics.  

This allowed her to study directional fire spread on sloped terrain without assuming the fire behaves predictably or spreads in a simple line. 

Her analysis confirmed something firefighters may know instinctively: fires race uphill. But when she compared her measurements with the values used in Canada’s official Fire Behaviour Prediction System, the numbers didn’t always line up.  

Real fires often moved faster, and the influence of slope wasn’t consistent from place to place. 

She tested the method on ponderosa pine and Douglas fir fuels often used in fire research. 

This highlights that small differences in fuel, wind and terrain can add to the unpredictability of fire and introduce important variations in how it spreads.  

Even under nearly identical conditions, the flames didn’t behave the same way twice. 

In practical terms, that means most fire spread is shaped by randomness—far more than today’s deterministic models capture. 

“These results show that we need to pair every spread estimate with a measure of uncertainty,” Tazik explains. “Simply multiplying by a slope factor isn’t enough. Fire is dynamic, and our models should acknowledge that.” 

Research supervisor Dr. W. John Braun says the project demonstrates how emerging computer vision tools can transform wildfire science.  

“Tazik proposed innovative ways to tackle this difficult modelling problem,” he says. “Her work shows how high-resolution perimeter data and advanced modelling can help us understand the real variability in fire behaviour. That’s essential if we want to move toward more probabilistic, data-driven prediction systems.” 

The study also included contributions from Dr. John R.J. Thompson, Assistant Professor of Data Science, Mathematics and Statistics, as well as other partners who provided the experimental and field video datasets.  

While the fuel experiments supported the research, Tazik alone led the segmentation and modelling components. 

Tazik says the next step is to expand the approach to more fuel types and fire conditions and use airborne or satellite imagery to study fire spread dynamics.  

With more Earth observation and remote sensing tools available, she sees an opportunity to build models that better capture wildfire dynamics while embracing the inherent uncertainty of fire, rather than smoothing it away. 

“Fires don’t behave perfectly,” she says. “Our tools shouldn’t pretend they do.” 

 

Evaluating building materials for climate impact and noise suppression



Even though timber requires extra material to insulate noise, it can still be more climate-friendly than steel or concrete.

HONOLULU, Dec. 3, 2025 — Many modern buildings are “green buildings,” adhering to a complex set of standards to ensure they are environmentally friendly and sustainably designed, with minimal impact on nature and the humans that inhabit them. These standards can govern everything from energy efficiency to construction materials used for acoustic privacy between rooms.

The sheer number of factors to consider when designing such a building can make even veteran architects stumble. Even deciding which construction material to use requires accounting for cost, lifetime carbon emissions, and acoustic performance.

Acoustic consultant George Edgar will present his assessment of various wall and floor types for their climate impact and acoustic performance Wednesday, Dec. 3, at 8:20 a.m. HST as part of the Sixth Joint Meeting of the Acoustical Society of America and Acoustical Society of Japan, running Dec. 1-5 in Honolulu, Hawaii.

Sound and noise have a major impact on our ability to focus and communicate, which is why acoustic requirements are often featured in green building standards, such as LEED in the U.S. and BREEAM in the U.K.

“The leading voluntary green building schemes in major English-speaking countries and Japan all include credits for acoustics,” said Edgar. “These schemes acknowledge the impact acoustic comfort has on the well-being of a building’s occupants.”

Edgar evaluated multiple materials, including timber, steel, and concrete, for their sound insulating properties along with their global warming potential (GWP), a measure of the carbon emissions involved in manufacturing them.

“The primary factor that influences GWP in the manufacturing phase is the amount of energy, and therefore carbon emissions, required to produce the material,” said Edgar. “Concrete and steel are more energy-intensive to produce than timber products, so they have higher GWP values in the manufacturing phase.”

Edgar found that, for floors with a given sound insulation performance, concrete could have a far higher GWP than timber, and walls that incorporated timber outperformed standard steel studs, even when they needed more wall linings to achieve the same acoustic performance.

Despite the importance of these results, little research has been done examining both the acoustic performance and climate impacts of building materials. Edgar is optimistic that his work will lead to buildings that are both quiet and climate-friendly.

“As acoustic consultants, an awareness of the GWP associated with the design solutions we specify can help us to make a positive impact on our environment for generations to come,” said Edgar. “I’d like to see more research in this area so we can all make more informed decisions when considering acoustics and sustainability.”

A fossil site in Bolivia preserves thousands of traces of dinosaurs who walked, ran, and swam along an ancient coastline, according to a study published December 3, 2025 in the open-access journal PLOS One by Raúl Esperante of the Geoscience Research Institute, California, U.S., and colleagues.

Bolivia is well known for its abundance of fossil sites preserving dinosaur footprints. These sites provide unique details into the behaviors of ancient species, but most such sites remain unpublished. In this study, Esperante and colleagues report an unprecedented variety of dinosaur tracks at the Carreras Pampas tracksite in Torotoro National Park.

Across nine study sites, the authors document more than 16,000 tracks left by three-toed theropod dinosaurs at the end of the Cretaceous Period. These tracks range in size from tiny (<10 cm) to large (>30 cm) and record a variety of dinosaur behaviors, including running, swimming, tail dragging, and even sharp turns. Most of these tracks are oriented roughly northwest-southeast, with ripple marks preserved in the sediment, suggesting these dinosaurs were roaming alongside the ancient shoreline.

The Carreras Pampas tracksite sets new world records for the number of individual dinosaur footprints, continuous trackways, tail traces and swimming traces. This unprecedented abundance suggests this was a high-traffic area, and the parallel orientation of some footprints might indicate groups of dinosaurs traveling together. The authors note that many more footprints remain to be explored at this tracksite and others in Bolivia.

“This site is a stunning window into this area’s past. Not just how many dinosaurs were moving through this area, but also what they were doing as they moved through.”

“It’s amazing working at this site, because everywhere you look, the ground is covered in dinosaur tracks.”
