Texas foundation makes massive $180M donation to Galveston hospital

historic gift

The University of Texas Medical Branch in Galveston (UTMB) has accepted a staggering $130 million grant from the Sealy & Smith Foundation, which, combined with the $50 million that the foundation donated in 2025 to establish the Department of Cardiovascular Medicine, is the largest bequest in UTMB history.

The grant will go to grow cardiovascular imaging, diagnosis, and treatment at UTMB by establishing an inpatient cardiovascular hub on the sixth floor of Jennie Sealy Hospital. In honor of the donation, the department is being renamed the Sealy Heart and Vascular Institute.

“The Sealy & Smith Foundation has a long history of investing in initiatives that transform health care for the people of Galveston and beyond,” said John Kelso, president of The Sealy & Smith Foundation Board of Directors. “We believe the Sealy Heart & Vascular Institute has the potential to redefine cardiovascular care in our region by bringing together exceptional physicians, advanced technology, innovative research and a commitment to improving patient outcomes. This additional investment reflects our confidence in UTMB’s vision and our belief that the Institute will have a lasting impact for generations to come.”

The Sealy & Smith Foundation was established in 1922 by John Sealy II and his sister Jennie Sealy Smith. Bolstered by the Sealy fortune built on shipping, oil, banking, and railroads, the Foundation has donated more than $1.2 billion to UTMB over the last century, linking the family legacy to healthcare, teaching, and research. It was John Sealy Sr. who contributed the initial $50,000 to build a hospital on the island, which opened right alongside the new medical school created by the state legislator in what was then Texas's largest and most economically powerful city.

Since then, the Foundation has helped grow UTMB into a world-class hospital. The cardiovascular care especially is well-regarded, making the 2025 Newsweek/Statista List of America's Best Hospitals.

“This extraordinary investment reflects The Sealy & Smith Foundation’s unwavering commitment to improving health and advancing medical excellence,” said Dr. Jochen Reiser, UTMB president and CEO of the UTMB Health System. “The partnership between UTMB and The Sealy & Smith Foundation is very strong. Built on generations of shared vision and trust, it continues to redefine what an academic health system can achieve. Together, we are building one of the nation’s premier cardiovascular programs integrating exceptional patient care, groundbreaking research, innovation and world-class education to improve the lives of patients throughout Texas and beyond.”

UTHealth Houston team joins NASA initiative to protect border drinking water

water watch

Climate change means far more to public health than living with hotter days. Transformations in our weather are contributing to challenges in accessing safe drinking water in some communities.

One of the most dire situations is along the US–Mexico border. The National Aeronautics and Space Administration (NASA) is seeking to address that issue with its Water Quality Applications program. An 11-researcher project led by a UTHealth Houston School of Public Health faculty member has been selected to participate.

“Drinking water is one of the most fundamental public health protections, but producing safe drinking water involves a delicate balance,” Yun Hang, assistant professor of environmental and occupational health sciences, said in a news release. Her team’s proposal was one of 93 that were submitted for funding through NASA’s Research Opportunities in Space and Earth Sciences (ROSES)-2025 program.

This is the first time that NASA has worked with a team devoted to water quality applications. The group, which includes researchers from across the nation, will use satellite observations of Earth, as well as hydrologic modeling, to potentially anticipate and act on water quality conditions as they change. Challenges addressed over the course of the three-year program, which kicked off in June, might include problems with water quality due to climate variability and increased pressure on water resources.

Hang’s team will focus on a pair of borderlands: Paso del Norte and the Rio Grande Valley.

“Working closely with El Paso Water ensures that our research addresses real operational needs while helping utilities better prepare for climate-related water quality changes and continue providing safe drinking water to communities across the Texas border region,” Hang added in the release.

She and the team will use data gathered by NASA on both past and future Earth-observing missions, which will allow them to track environmental changes that may affect source water quality. Combined with past water treatment records and hydrologic models, the team will also utilize artificial intelligence to develop predictive tools that aim to stop issues before they become larger hurdles to water safety.

Another one of the project’s goals is to create visualization tools and source water summaries that can be utilized by those without scientific expertise. The tools will be produced in English and Spanish to further broaden their accessibility.

The hope is that the materials made by the team will also go far beyond the border, with protocols that can be adapted or adopted by other areas dealing with water quality issues.
