Heart health innovation is at a major moment in history — and Houston is at the center of it.

Last summer, Dr. Joseph Rogers, president and CEO of the Houston-based Texas Heart Institute, joined the Houston Innovators Podcast to share how he came to be at the helm of THI, as well as the incredible technologies the institute is working on to address heart failure, a global epidemic affecting at least 26 million people worldwide, 6.2 million adults in the U.S.

This month, one of THI’s technologies reached a major milestone. BiVACOR, a Houston company successfully implanted the company's first Total Artificial Heart in a human. The device was implanted in the patient on July 9. Eight days later, a donor heart became available and was transplanted into the patient, removing the TAH, establishing the device as a successful bridge-to-heart-transplant solution for patients, THI reported.

In addition to this breakthrough in health tech, THI is focused on addressing Cardiometabolic Syndrome at a new conference on Friday, August 23, in Houston. The full-day symposium will take place in collaboration with Arianna Huffington, the founder and CEO of Thrive Global. Dr. Rogers is co-directing the program with Dr. Stephanie Coulter, medical director for THI Center for Women’s Heart & Vascular Health.


In the episode, Rogers explains why he's bullish on Houston and THI leading heart health innovation alongside other health care organizations — nonprofits, universities, local government — to collaborate 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."

Houston hardtech accelerator names 8 founders to 2026 cohort

hardtech fellows

Hardtech-focused organization Activate has named 50 new members to its 2026 cohort of scientists, which includes eight startups joining Activate Houston.

Activate aims to support scientists at "the outset of their entrepreneurial journey." It partners with U.S.-based funders and research institutions to support its fellows in developing high-impact technology. Its fellows receive a living stipend, research and development funding, connections from Activate's robust network of mentors and access to a curriculum specific to the program for two years.

This year's fellows represent 41 companies from 22 U.S. cities and 11 states.

“This cohort clearly demonstrates that the next industry-defining companies won't choose between modern technology and deep science; they'll be built by combining both,” Cyrus Wadia, CEO of Activate, said in the announcement. “These are the scientists and engineers turning our most urgent global challenges into the companies that will deliver a more sustainable future.”

The Houston fellows are working across the energy, space, AI infrastructure and agriculture sectors. They include:

  • Sophie Clare Broun, founder of Anning Corporation, which is producing clean hydrogen by stimulating naturally occurring geologic deposits
  • Kathy Andersen, founder of Brint Tech, which builds optical sensing systems that quantify hydrogen for infrastructure operators
  • Dorsa Talebi, founder of Kinetiq Drive, which builds rare-earth-free, contact-free electric motors with wireless rotors for small appliances and heavy industry alike
  • Neethu Pottackal, founder of Nivera, which is developing natural, edible coatings made from agricultural byproducts to reduce food waste and extend the shelf life of fresh food
  • Jonathan Huffman, founder of Orbital Arc, which is shrinking spacecraft propulsion to a microchip powerful enough for deep space
  • Tim Lee, founder of Renesin, which develops advanced materials for faster, more efficient AI hardware
  • Joshua Livingston, founder of Selerra Separations, which is developing high-performance membranes that cut the cost and energy consumption of water treatment
  • Wenli Jiang, founder of SwieNitro Recovery, which is developing technology that converts nitrogen-rich waste streams into valuable fertilizer

"Home to the largest concentration of engineers in the United States and a dense ecosystem of Fortune 100 and Fortune 500 companies, Houston is uniquely positioned for scientists tackling large-scale industrial challenges. Activate Houston fellows are connected to the city's deep networks in energy, chemicals, and materials," Activate said in the announcement.

Activate named its inaugural Houston cohort in 2024. It has other hubs in Boston, New York, and Berkley, California—where Activate is headquartered. The organization also offers a virtual and remote cohort, known as Activate Anywhere. Nationally, it has supported 346 fellows and 276 companies since 2015.

Activate Houston is led by managing director Jeremy Pitts, who co-founded Greentown Labs in Boston. It is based out of the Ion. The latest cohort is Activate Houston's third. Read more about the last year's cohort here.

Rice, Houston Methodist award $90K for cancer research projects

seed grants

Rice University’s Synthesis X Center, in partnership with the Houston Methodist Neal Cancer Center, announced earlier this month the organizations would award $90,000 in seed grant funding to two projects that could help fight cancer. One would ease the pain of chemotherapy, while the other could change the way the progression of leukemia is tracked.

“We’re excited to be collaborating with the Neal Cancer Center to support collaborative, novel and interdisciplinary proposals to improve cancer care and outcomes,” Han Xiao, Rice professor of chemistry and the director of the SynthX Center, said in a news release. “Together, we can achieve translational excellence.”

The projects

Chemotherapy is one of the most effective cancer treatments, but it can be hard on the body. The human body doesn’t like being injected with radioactive material, especially the skin around the injection point, which can become extremely irritated. For patients in long-term treatment, the skin irritation can be more than just a bother; it can lead to infections that are dangerous to a compromised immune system.

Angel A Marti, a professor of chemistry at Rice University, and Biana Godin, an associate professor of nanoscience at Houston Methodist Research Institute, are experimenting with metal nanoclusters as a way to block radiation at the injection site. The nanocluster could be applied in a cream or a gel on the skin, serving as a type of shield against the harsh radioactive material.

Meanwhile, Yuan Ma, an assistant professor of chemistry at Rice, and Shu-Hsia Chen, a professor of immunology at Houston Methodist Research Institute, are working with m6A. Discovered in the 1970s, m6A is the most prevalent chemical modifier found in mRNA in mammals. It is prevalent in many cancers, including leukemia.

Ma and Chen are working on measuring the amount of m6A in leukemia to see if it can determine the most effective cancer treatments. The team is also experimenting with ways to shut off m6A to see if it makes current leukemia treatments more effective.

Progress from SynthX

SynthX was first launched in April 2024 to turn research from Rice and Houston Methodist into real-world cancer treatments. Within a year, the center had secured $1.5 million in grant money to work on crossing the blood-brain barrier in brain cancer treatments. These latest awards show that SynthX Center continues to bridge the worlds of research and clinical practice.

“This collaboration reflects a shared commitment to team science in cancer research,” Daniela Matei, the director of the Houston Methodist Neal Cancer Center, added in the release. “These are the types of translational and pioneering projects that lead to transformation in patient care.”'

The SynthX Center awarded $90,000 in seed grants to three teams in 2025 and $80,000 to three teams in 2024.

Tesla self-driving mode wasn't to blame in Houston-area crash, report suggests

Tesla news

Federal safety investigators looking into a runaway Tesla that killed a grandmother in her home say the driver had pressed the accelerator to full speed, suggesting the vehicle's self-driving software was not to blame.

The driver had told police that he had the self-driving software turned on, but a report from the National Transportation Safety Board concluded that he had actually overridden that feature when he pushed hard on the pedal. Moments later the Tesla Model 3 raced down a residential street in Katy, Texas, at highway speeds, slammed into a brick home and killed a 76-year-old woman standing in the front room.

The crash last month drew national attention because Tesla CEO Elon Musk is seeking to reassure the public its self-driving feature is safe as he prepares to turn hundreds of thousands of Teslas already on the road into fully automatic vehicles and begin selling two-seated Cybercabs missing steering wheels and pedals.

The crash came two months after officials at a separate federal agency, the National Highway Traffic Safety Administration, announced it was elevating a 2024 investigation of the self-driving feature to new “engineering analysis” level, raising the possibility of a recall of 3.2 million Tesla vehicles.

That NHTSA probe was triggered by crashes where the self-driving feature failed to alert drivers to take control in fog and other poor visibility conditions.

The agency opened an investigation last year into 58 incidents in which Teslas reportedly violated traffic safety laws while using self-driving technology, leading to more than a dozen crashes and fires and nearly two dozen injuries.

Separate from the National Transportation Safety Board, NHTSA is also looking into the Tesla house crash in Texas, one of 46 “special crash” investigations of Tesla's self-driving or driver-assistance technology in the past decade, according to the agency’s records. In more than a dozen of those crashes, at least one person — a driver, passenger or pedestrian — was killed.

Tesla had originally called its driver assistance software Full Self-Driving, or FSD, but auto experts and regulators complained it was misleading because drivers must always keep their eyes on the road and be ready to take over at any time.

The company has since changed the name to Full Self-Driving (Supervised).

Video of the Katy, Texas, accident shows the Tesla traveling at more than 70 mph (112.65 kilometers per hour), jumping a curb then tearing across a lawn before crushing through a brick wall of a home. A woman standing feet away, Martha Avila, was found amid piles of crumbling plaster, split beams and bits of furniture and rushed to a hospital but died.

Sales of Tesla cars still haven't recovered fully from boycotts last year over Musk's political stands, but the stock is rising anyway as he has successfully shifted attention away from the sales figures. He says they matter less now that the company is on the cusp of major technological advances, such as turning Teslas into hands-free vehicles and having its Optimus robots take over for humans for tasks at home and work.

Tesla stock has risen 22% in the past year and is currently trading at 170 times expected annual earnings compared to 20 for the S&P 500.

For its second-quarter financial results, financial analysts surveyed by FactSet expect earnings per share will barely budge — 32 cents versus 33 cents a year earlier — continuing a sixth quarter streak of flat or falling profits.
