For 60 years, the Texas Heart Institute has been a part of Houston's innovation DNA. The organization's founder, Dr. Denton Cooley, performed first total artificial heart implantation in 1969 at THI. Now, decades later, the institutions third CEO continues to lead the innovation within cardiovascular care.

"Despite all of the advances, cardiovascular disease is still one of the largest killers of Americans. It actually kills more Americans than all types of cancer combined," Dr. Joseph Rogers, who was appointed president and CEO of THI in 2021, says on the Houston Innovators Podcast.

Rogers shares just a fraction of what the medical professionals are working on at THI on the show — from developing a drug that can improve the efficacy cell therapies, vaccines, and more to revolutionary stem cell treatments. Even with all this groundbreaking innovation in cardiovascular treatment, Rogers says one of the most crucial elements is prevention.

"The challenge of preventative medicine in general terms is there has been an under investment in terms of research," Rogers says. "I also think that many of us who live in developed countries have said, 'I think I can just take a pill to manage an underlying problem and I can continue to do whatever I'd like.'

"We use medicine as a crutch to allow us to continue living an opulent lifestyle," he continues.

THI is on a mission to evolve that way of thinking, Rogers says, but it's a comprehensive cultural shift that's needed.

"Medicine can control about 20 percent of this," Rogers says. "The rest is driven by the social drivers of health — early childhood experiences, food deserts, a lack of safe exercise facilities."

Rogers says health care organizations are going to need to partner with other players — nonprofits, universities, local government — in ways never been done before. And THI is dedicated to this mission.

"We should act as a convener," Rogers says. "Houston is the place to do this.

"The reason I think this is such an important community to address this problem is it's the most diverse city in the United States. And I've never lived anywhere or heard of another city that I was so convinced believed they could do anything they set their minds to. It's about making the community aware of the problem and a potential solution — and then working on trying to solve it," he continues. "But I think all of the pieces are here to show the world how to do this at a community level."

Rogers shares more of his optimism about Houston as a heart health leader and innovator on the show. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

FAA demands investigation into SpaceX's out-of-control Starship flight

Out of this world

The Federal Aviation Administration is demanding an accident investigation into the out-of-control Starship flight by SpaceX on May 27.

Tuesday's test flight from Texas lasted longer than the previous two failed demos of the world's biggest and most powerful rocket, which ended in flames over the Atlantic. The latest spacecraft made it halfway around the world to the Indian Ocean, but not before going into a spin and breaking apart.

The FAA said Friday that no injuries or public damage were reported.

The first-stage booster — recycled from an earlier flight — also burst apart while descending over the Gulf of Mexico. But that was the result of deliberately extreme testing approved by the FAA in advance.

All wreckage from both sections of the 403-foot (123-meter) rocket came down within the designated hazard zones, according to the FAA.

The FAA will oversee SpaceX's investigation, which is required before another Starship can launch.

CEO Elon Musk said he wants to pick up the pace of Starship test flights, with the ultimate goal of launching them to Mars. NASA needs Starship as the means of landing astronauts on the moon in the next few years.

TMC med-tech company closes $2.5M series A, plans expansion

fresh funding

Insight Surgery, a United Kingdom-based startup that specializes in surgical technology, has raised $2.5 million in a series A round led by New York City-based life sciences investor Nodenza Venture Partners. The company launched its U.S. business in 2023 with the opening of a cleanroom manufacturing facility at Houston’s Texas Medical Center.

The startup says the investment comes on the heels of the U.S. Food and Drug Administration (FDA) granting clearance to the company’s surgical guides for orthopedic surgery. Insight says the fresh capital will support its U.S. expansion, including one new manufacturing facility at an East Coast hospital and another at a West Coast hospital.

Insight says the investment “will provide surgeons with rapid access to sophisticated tools that improve patient outcomes, reduce risk, and expedite recovery.”

Insight’s proprietary digital platform, EmbedMed, digitizes the surgical planning process and allows the rapid design and manufacturing of patient-specific guides for orthopedic surgery.

“Our mission is to make advanced surgical planning tools accessible and scalable across the U.S. healthcare system,” Insight CEO Henry Pinchbeck said in a news release. “This investment allows us to accelerate our plan to enable every orthopedic surgeon in the U.S. to have easy access to personalized surgical devices within surgically meaningful timelines.”

Ross Morton, managing Partner at Nodenza, says Insight’s “disruptive” technology may enable the company to become “the leader in the personalized surgery market.”

The startup recently entered a strategic partnership with Ricoh USA, a provider of information management and digital services for businesses. It also has forged partnerships with the Hospital for Special Surgery in New York City, University of Chicago Medicine, University of Florida Health and UAB Medicine in Birmingham, Alabama.
