In 1969, Dr. Denton A. Cooley implanted the first total artificial heart in a living patient. Most Houstonians know Cooley’s name, but fewer can name his colleague, Dr. Domingo Liotta, who created the device. Liotta died last year at the age of 97, but his work continues at the Texas Heart Institute.

Meet Yaxin Wang, PhD. The research engineer leads the IDEA Lab at THI. IDEA stands for Innovative Device & Engineering Applications, an apt description of what Wang and her colleagues do. She’s currently focused intensely on projects that could radically change transplantation for patients in need of an artificial heart or new, healthy lungs.

Specifically, Wang is helping to develop a pediatric left ventricular assist device (NeoVAD) to mechanically pump that part of the heart in infants and small children born with heart defects.

“There aren’t a lot of options for very small kids,” explains Wang. “That’s why we’re working on an implantable LVAD for very young kids.”

In fact, as many as 14,000 children with congenital heart disease are hospitalized each year waiting for a new heart, but only around 500 pediatric transplants actually take place.

Essentially, once patients reach their teens, their chest cavities are large enough for an adult donor heart. But smaller children means smaller rib cages and fewer available hearts. For children born with heart disease, Wang’s LVAD could be a lifesaver. Because she has crafted minimally invasive devices that were developed for long-term use, patients could live far longer than before.

The project, funded by a $2.8 million NIH grant, has a big name attached. Dr. O.H. Frazier is a THI legend who claims to have performed 900 LVAD implantations, not to mention some 1,200 heart transplants. In April, the team published their initial findings regarding the success of and improvements in making rotary LVADs over the last half-century.

A different team, also led by Frazier and Wang, received a pair of grants this summer. That includes $2.8 million from the NIH and a total of $7.8 million from a DoD focused program and a THI sub-award. Their work will center on a novel centrifugal left-ventricular assist device intended for end-stage heart failure patients, a potentially safer alternative to a heart transplant.

But Wang isn’t solely focused on the heart. Working with Dr. Gabriel Loor, a cardiothoracic surgeon at Baylor College of Medicine, Wang is also responsible for a method of preserving the lungs for a longer stretch of time, which would allow for further transport, and in the more distant future, potential genetic modification before transplantation. Using animal models for the moment, “they can survive for several hours without any issues,” says Wang.

The pioneering researcher is well on her way to making a name for herself at the Texas Heart Institute and beyond. And soon, she’ll be saving countless lives.

Massive $32M gift from former patient, new UH deal pump big changes into Houston organization

all heart

Leadership at The Texas Heart Institute has two major things to celebrate. First, it just received a $32 million donation from a patient — the largest charitable donation in its history.

Shortly after that news came out, the institute announced a new partnership with the University of Houston Tilman J. Fertitta Family College of Medicine that allows those UH medical students to join a clinical rotation at The Texas Heart Institute. The alliance means valuable insights and experience with both inpatient and outpatient cardiology for UH's future doctors.

"Students will have the chance to develop their skills in the diagnosis and management of cardiovascular conditions and will be taught by outstanding clinical educators,” said Dr. Joseph G. Rogers, president and CEO of The Texas Heart Institute and heart failure specialist at The Texas Heart Institute Center for Cardiovascular Care, in a press release announcing the news.

A game-changing gift that's all heart

As for that mammoth gift, the $32 million donation comes from Dr. Frederick M. Weissman, a neurologist from New York who was a patient at the Institute 40 years ago. Fittingly, huis gift will be used to support cardiovascular research.

This isn't Weissman's first gift to the institution. That came following his experience there in the mid-1980s, when he was treated by world-renowned cardiac surgeon Dr. Denton A. Cooley.

In November of 1986, Weissman wrote a check for $5,000; another followed the next month, with a note that read, in part, “my conscience compels me to make another contribution to The Texas Heart Institute. I don’t think I could ever repay you for what you and your staff have done for me.” Weissman and Cooley would go on to be friends throughout their lives.

When Dr. Weissman died in 2005, he left The Texas Heart Institute $500,000. The organization recently received the residual of his estate — valued at more than $32 million.

“Those of us who were fortunate enough to work with and be trained by Dr. Cooley know he was much more than just an incredibly gifted surgeon," renowned transplant surgeon and Co-director of THI’s Center for Preclinical Surgical & Interventional Research, Dr. O.H. “Bud” Frazier, said in press materials announcing the donation. "He established lifelong relationships with his patients and encouraged all of us to do the same. Dr. Weissman’s extraordinary generosity reflects the impact Dr. Cooley still has on the Institute he founded.”

A big leap for THI and the Coogs

Looking ahead, this game-changing gift and new affiliation with UH promises big things for students, doctors, researchers, and patients.

Medical students in rotation at The Texas Heart Institute will be exposed to progressive clinical care, allowing them to gain a deep understanding of the etiology, pathophysiology and management of cardiovascular disease from prevention to the most contemporary treatments available today. This level of hands-on experience is invaluable for future physicians, and will certainly contribute to the advancement of cardiovascular medicine.

"We are honored to launch this new affiliation with Fertitta Family College of Medicine,” said Dr. Jorge Escobar, director of undergraduate medical education at The Texas Heart Institute. "With new advances in diagnostic imaging, bedside testing, and clinical trials coupled with the complex care we provide to our patients, the rotation will be an impactful experience for the students."

Pumping with growth

Meanwhile, THI recently established The Texas Heart Institute Research Innovation Fund to propel the next generation of cardiovascular research by sparking discovery, supporting innovation, and recognizing excellence in high-risk, high-reward scientific exploration.

To that end, $5 million of the Weissman bequest has been designated to match philanthropic commitments of $10,000 or greater made to THI’s Research Innovation Fund and its priority initiatives in 2023, allowing donors the opportunity to double the impact of their research investment.

Founded in 1962, THI performed the first successful heart transplant and total artificial heart implant in the United States. It has gone on to become one of the world's leading institutions for cardiovascular treatment and research.

Rice University partners with astronaut foundation to offer new STEM scholarship

space scholars

Rice University has partnered with The Astronaut Scholarship Foundation (ASF) to offer a new scholarship opportunity for junior or senior STEM majors, beginning this spring.

The prestigious Astronaut Scholarship includes up to $15,000, mentorship, networking and a paid trip to the ASF Innovators Symposium and Gala. The scholarship is funded by the James A. Lovell Jr. Family Endowment, in honor of the late American astronaut and founder of the ASF.

“This scholarship opportunity represents an exciting new avenue for Rice STEM students to synthesize their experiences in courses and research and their commitment to advancing the public good as leaders in their field,” Danika Brown, executive director for the Center for Civic Leadership at Rice, said in a news release. “We are so grateful to the Lovell family and to the foundation for investing in Rice students, and we are confident that the foundation will be impressed with our nominees and that selected students will have a life-changing experience as astronaut scholars.”

The Rice Space Institute and the Center for Civic Learning recently hosted the ASF at the Ralph S. O’Connor Building for Engineering and Science.

At the ASF event, Jeff Lovell—son of James Lovell, who commanded Apollo 13 and flew on Apollo 8—announced the scholarship aimed at Rice STEM students. Charlie Duke, who served as spacecraft communicator for the Apollo 11 Moon landing and as the lunar module pilot for Apollo 16, also spoke at the event.

The ASF awarded 74 scholarships to students from 51 universities across the U.S. last May.

The ASF awarded its first seven $1,000 scholarships in 1986 to pay tribute to the Mercury 7 astronauts. It has since awarded more than $10 million to more than 850 college students.

So far, only students from Texas A&M University and the University of Texas at Austin have received the scholarship in Texas.

Houston hospital first in U.S. to use new system for minimally invasive surgery

sharper images

Houston’s Baylor St. Luke’s Medical Center has introduced an innovative new surgical imaging system that will allow surgeons to increase the number of minimally invasive procedures as well as reposition on the fly during operations.

Minimally invasive surgery has been shown across the board to improve patient outcomes with less chance of infection and shorter recovery times compared to traditional open surgery. However, the human body is not exactly easy to work on through small incisions, necessitating the development of state-of-the-art cameras and imaging technology to guide surgeons.

Enter GE HealthCare’s Allia Moveo, now a part of the Baylor St. Luke’s Medical Center operating room. Using cutting-edge technology, it uses the same high-definition imaging usually seen in the catheterization lab at speeds fast enough to respond to shifting surgical conditions. Its cable-free setup allows surgeons to switch positions much faster, and it features advanced 3D imaging that compensates for breathing motion and interference from metal implants.

Its design supports a range of cardiovascular, vascular, non-vascular, interventional and surgical procedures, according to CommonSpirit Health, a nonprofit Catholic health network, of which Baylor St. Luke's is a member.

“This innovative platform enhances how our clinicians navigate complex minimally invasive procedures by improving mobility, image clarity, and workflow efficiency. It strengthens our ability to deliver precise, patient-centered care while supporting our teams with technology designed for the evolving demands of modern interventional medicine,” Dr. Brad Lembcke, president of Baylor St. Luke’s Medical Center, said in a news release from Baylor and the Texas Heart Institute.

Baylor St. Luke’s is the first hospital in the U.S. to use the Allia Moveo technology. The definition and responsiveness of the new system allow surgeons to navigate the body with greater accuracy and smaller incisions, even for very delicate operations.

“Allia Moveo gives us the flexibility and image quality needed to manage increasingly complex minimally invasive procedures with greater confidence,” Dr. Gustavo Oderich, vascular surgeon and professor of surgery at Baylor College of Medicine, added in the release. “The ability to quickly reposition the system, obtain high-quality 3D imaging, and integrate advanced guidance tools directly into the workflow enhances procedural accuracy. This technology supports our mission to push the boundaries of what is possible in endovascular and interventional surgery.”

Houston clocks in as one of the hardest working cities in America

Ranking It

Houston and its residents are proving their tenacity as some of the hardest working Americans in 2026, so says a new study.

WalletHub's annual "Hardest-Working Cities in America (2026)" report ranked Houston the 37th most hardworking city nationwide. H-town last appeared as the 28th most industrious American city in 2025, but it still remains among the top 50.

The personal finance website evaluated 116 U.S. cities based on 11 key indicators across "direct" and "indirect" work factors, such as an individual's average workweek hours, average commute times, employment rates, and more.

The U.S. cities that comprised the top five include Cheyenne, Wyoming (No. 1); Anchorage, Alaska (No. 2); Washington, D.C. (No. 2); Sioux Falls, South Dakota (No. 4); and Irving, Texas (No. 5). Dallas and Austin also earned a spot among the top 10, landing as No. 7 and No. 10, respectively.

Based on the report's findings, Houston has the No. 31-best "direct work factors" ranking in the nation, which analyzed residents' average workweek hours, employment rates, the share of households where no adults work, the share of workers leaving vacation time unused, the share of "engaged" workers, and the rate of "idle youth" (residents aged 16-24 that are not in school nor have a job).

However, Houston lagged behind in the "indirect work factors" ranking, landing at No. 77 out of all 116 cities in the report. "Indirect" work factors that were considered include residents' average commute times, the share of workers with multiple jobs, the share of residents who participate in local groups or organizations, annual volunteer hours, and residents' average leisure time spent per day.

Based on data from The Organisation for Economic Co-operation and Development (OECD), WalletHub said the average American employee works hundreds of more hours than workers residing in "several other industrialized nations."

"The typical American puts in 1,796 hours per year – 179 more than in Japan, 284 more than in the U.K., and 465 more than in Germany," the report's author wrote. "In recent years, the rise of remote work has, in some cases, extended work hours even further."

WalletHub also tracked the nation's lowest and highest employment rates based on the largest city in each state from 2009 to 2024.
