It's hard to understate the impact Dr. William Cohn has had on cardiovascular health as a surgeon at the Texas Heart Institute or on health care innovation as the director of the Center for Device Innovation at the Texas Medical Center. However, his role as chief medical officer of BiVACOR might be his most significant contribution to health care yet.

The company's Total Artificial Heart is unlike any cardiovascular device that's existed, Cohn explains on the Houston Innovators Podcast. While most devices are used temporarily for patients awaiting a heart transplant, BiVACOR's TAH has the potential to be a permanent solution for the 200,000 patients who die of heart failure annually. Last year, only around 4,000 patients were able to receive heart transplants.

"Artificial hearts historically have had bladders that ejected and filled 144,000 times a day. They work great for temporary support, but no one is suggesting they are permanent devices," Cohn says on the show.

The difference with BiVACOR's device is it abandons the bladder approach. Cohn explains that as assist pumps evolved — something his colleague, Dr. Bud Frasier, had a huge impact on — they featured new turbine and rotor technology. Daniel Timms, BiVACOR's founder and CTO, iterated on this technology beginning when he was a postdoctoral student at Queensland University of Technology in Australia.

"BiVACOR is the first artificial heart that leverages what we learned from that whole period — it has no bladders, it has no valves. It has one moving part, and that moving part is suspended in an electromagnetic field controlled by a computer and changed thousands of times a second," Cohn says. "It will never wear out, and that's why we think it's the world's first total artificial heart."

The company is seeing momentum, celebrating its first successful human implantation last month. The device was used for eight days on a patient at Baylor St. Luke’s Medical Center before the patient received a heart transplant.

Cohn says that BiVACOR has plans to use the TAH as "bridge-to-transplant" device in several other surgeries and expects to get FDA approval for that purpose in the next three to four years before working toward clearance for total artificial heart transplants.

Cohn has worked to support medical device startups at CDI at TMC for the seven years it has existed — first under Johnson and Johnson and then under TMC when it took the program over. He describes the center and its location as the ideal place for developing the future of health care, with Houston rising up to compete with regions known for medical device success — both coasts and Minnesota.

"Being in the shadow of the largest medical center on the planet — 106,000 employees show up there every 24 hours," Cohn says, "if you want to innovate, this is the place to do it."

Play it back: How this Houstonian is leading heart health innovation

HOUSTON INNOVATORS PODCAST EPISODE 246

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 health care leader on a mission to innovate an end to heart failure

cardiology cured

Emerson Perin’s end goal isn’t to treat heart failure. The medical director of The Texas Heart Institute says that he has his sights set firmly on curing the malady altogether. And, with the power of innovation and a strong team, the Houston-based cardiologist has a good chance of meeting his objective.

Perin first came to THI for fellowship training in 1988, following his residency in Miami and medical school in his birthplace of Brazil.

“This is a very special place,” the physician and researcher, whose titles also include director for THI’s Center for Clinical Research and vice president for medical affairs, tells InnovationMap. “It has a worldwide-reaching reputation. I’ve always liked research and this is a great place in terms of innovation and practicing high-level cardiology.”

For decades, Perin has followed in THI founder Denton Cooley’s footsteps with world-changing research. In 2001, the founding medical director of THI’s Stem Cell Center was the first person to inject stem cells into a failing human heart. It led to a trial of 17 patients that year.

“A couple of the patients did remarkably well — more than you could ever expect. These guys who couldn’t’ walk across the room pretty much were jogging on the beach. That gave me the initial insight that this works,” Perin recalls.

What exactly is heart failure? The term refers to the condition of a heart that can’t pump enough blood to sustainably power the body through oxygenation of the tissues from blood flow. It may sound like a death sentence, but with appropriate care, it can usually be managed with medicines and if worsening occurs, devices and, ultimately, heart transplantation.

And Perin is proving that there’s a lot of life ahead for heart failure patients. Earlier this year, he published another groundbreaking clinical trial, DREAM-HF. The largest clinical trial of cell therapy for patients with chronic heart failure to-date included 580 patients at 52 sites throughout North America.

With the goal of getting a new cell therapy approved for heart failure, the primary endpoint was to prove that the therapy could prevent recurrent hospitalizations.

“It was a total negative,” says Perin. That’s because the cells don’t have a decongestant effect such as the medicines currently used to treat heart failure.

But that doesn’t mean that the trial was a failure. Quite the opposite. That’s because Perin and his team proved something else: The trial was able to prove that there was significant improvement in patients with inflammation. After those patients were injected with mesenchymal precursor cells (MPC), they showed a 70-percent reduction in heart attacks and strokes. Cardiovascular deaths also decreased.

These are blockbuster numbers, and big news for patients dealing with heart failure. What it means is that the cells addressed a different aspect of heart failure that until now had been left untreated which was the inflammation — how heart failure starts and what keeps it going.

So what’s next? Going to the FDA.

“They said, ‘We can’t approve it with one trial, but we’ll approve it with two,’” says Perin.

This time, his primary endpoint will be tailored to suit the positive outcome he knows he’ll be able achieve. This next round will begin in 2024.

Once the FDA approves a new catheter system for injecting the heart with stem cells and genes, the team will proceed with new studies. Gene therapy will be another frontier for Perin — and patients with heart failure.

“I think the combination of cells and genes is even more powerful,” he says. “That will help save lives in a completely new way and do away with heart failure.”

Perin's work is just one piece of the puzzle, and Dr. Joseph Rogers, who was appointed president and CEO of THI in 2021, is leading the organization's initiative in several ways. THI, recently buoyed by a $32 million donation from a patient — the largest charitable donation in its history — is exploring several innovative therapeutics, devices, and treatments.

THI recently received a two-year, $1.14 million grant from The National Heart, Lung, and Blood Institute to develop a novel, first-in-class drug to treat the cardiovascular disease that arises from atherosclerosis. Another THI innovator, Camila Hochman-Mendez — along with her research team — is studying the effects of regenerative medicine on hearts.

Planned KBR spinoff scores $1B NOAA deal for extreme weather forecasting

weather watch

Amid a major spinoff, Houston-based KBR's Mission Technology Solutions business has been awarded a five-year contract for up to $1.1 billion from NOAA’s National Weather Service to help predict and combat extreme weather conditions.

Under the follow-on Commercial Data Program National Mesonet Program (CDP NMP) contract, KBR will provide weather and observational data from commercial stations, university and research campuses, and other non-federal providers nationwide. The information collected will assist in predicting severe temperatures and high-impact weather conditions like extreme storms.

"This award underscores KBR's proven track record of delivering vital data that strengthens national forecasting capabilities," Todd May, KBR’s senior vice president of Mission Technology Solutions, said in a news release.

According to a separate release from NOAA, the contract expands upon KBR's existing relationship with the agency. KBR will work with about 70 private industry partners on services such as data recording, collection, aggregation and processing, and will lead the CDP NMP's "network of networks."

“NOAA gathers environmental information from a wide variety of sources, and a growing list of private industry partners have joined our agency to collect this vital data,” Ken Graham, director of NOAA’s National Weather Service, said in the release. “This agreement streamlines the process that turns raw data into the gold-standard forecasts that Americans depend on.”

KBR will utilize its Speed to Mission ImpactSM technology for the project to supply data from across regions, measurement types, and system configurations. Both KBR and NOAA say the expanded data collection contract will help the agency create more accurate and timely forecasts, particularly for severe weather and extreme events, while also creating a path for new weather-observation technologies.

KBR has supported the CDP NMP for more than 9 years. The program will be managed in Greenbelt, Maryland.

"We're driving expanded integration of commercial sensor and data sources into this platform and are honored to know our work helps forecasters give their communities earlier warnings and more time to prepare for dangerous weather,” May added in a release.

KBR’s Mission Technology Solutions business will be rebranded as Trinzic after its planned spin-off, the company announced last month. The spin-off is expected to close in January 2027.

Trinzic will work as an independent, publicly traded company focused on technology and engineering services for the space and national security sector. KBR will remain a separate publicly traded company that will focus on sustainable technology and services to support the energy transition.

This is the salary required to live comfortably in Texas in 2026

Money Matters

A new national report looking at the income it takes to live comfortably in each of the 50 states has revealed Texans need to earn slightly less now than a year ago.

SmartAsset analyzed what a single individual, as well as family of four, must earn to cover minimum basic needs adjusted using the 50/30/20 budgeting rule. The resulting estimate represents the annual, pre-tax income needed to live comfortably in every U.S. state.

A single, full-time worker needs to make $90,563 to live comfortably in the Lone Star State, the report found, which is down a meager 0.2 percent from last year ($90,771).

Under the 50/30/20 budgeting strategy, that means a single Texas earner would have $45,282 to spend on necessities like housing and utilities, $27,169 for discretionary spending, and $18,113 for emergencies or retirement savings.

Texas ranked 34th nationally in SmartAsset's list of states with the highest income needed for a single adult to live "in sustainable comfort" in 2026. Only five other states — Tennessee, Maryland, Louisiana, North Carolina, and Mississippi — saw a decline in the income needed to live comfortably this year.

For a family of four to live comfortably in Texas, income requirements change significantly, according to the findings. To support a two-child household, a family needs $203,424 in combined total household income to be considered financially stable. This is down slightly from 2025, when SmartAsset reported a family of four in needed $204,922 to live comfortably in Texas.

This is a comfortable lifestyle for a family of four in Texas, according to the report:

$101,712 dedicated to necessities and living expenses
$61,027 dedicated to discretionary spending
$40,685 dedicated to emergencies, savings, or debt repaymen

According to the report, a family of four now needs to make at least $200,000 to live comfortably in 40 U.S. states, a figure that is far out of reach for many American families.

"As housing, grocery, transportation and other essential costs pressure household budgets, earning a six-figure salary no longer guarantees financial comfort in much of the U.S.," the report said. "A single adult now needs at least $80,000 a year to live comfortably in every state, while the threshold exceeds $100,000 in nearly half of states. For a family of four, the income needed to live comfortably is as much as $329,000."

Still, earning the minimum income to live comfortably in Texas doesn't guarantee financial stability in the Lone Star State's major cities. Earlier this year, SmartAsset determined single residents in Houston need to make about $90,000 to qualify as financially stable, while families of four need around $205,000.

Texas is the 7th hardest working state in America for 2026, says report

Labor Day Report

Texans pride themselves on being industrious, and a new report has confirmed Texas as one of the 10 most hardworking states in America in 2026.

The Lone Star State claimed the No. 7 spot this year in a slight dip from its 2025 ranking, where it appeared in the top five. Texas last ranked 7th in 2024, but the state has consistently appeared among the top 10 for nearly a decade.

WalletHub determined the rankings after analyzing 10 "direct" and "indirect" work factors across all 50 states, and then graded each metric on a 100-point scale, where a score of 100 signified the "hardest working." Analysts then examined each state’s weighted average across all metrics to calculate its overall score and used the resulting scores to rank-order the states.

There was only a 10.32-point difference between Texas and South Dakota, who claimed the top spot as America's hardest working state in 2026 with a score of 64.59 out of a possible 100 points.

Texas ranked 6th nationally in the "direct" work factors category, which examined the following six metrics:

The state's 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 — those that are "involved in, enthusiastic about, and committed to their work and workplace," as defined by Gallup.
The rate of "idle youth" — individuals aged 18-24 who are not currently enrolled in school, not working, and have no degree beyond a high school diploma or GED.

Texas ties with Louisiana for the second highest average workweek hours nationwide, with Alaska topping the list with the No. 1 longest workweeks in America. Alaska is the only state where workers clock in more than 40 hours per week at their jobs, with WalletHub reporting Alaskans work 41.4 hours on average weekly.

In the "indirect" work factors category — which encompassed workers' average commute times, the share of workers with multiple jobs, annual volunteer hours per resident, and the average leisure time spent per day — Texas ranked 36th nationwide.

Here's how WalletHub ranked Texas in three individual metrics:

No. 10 – Average commute times
No. 20 – Average leisure time spent per day
No. 30 – Employment rates

According to the World Economic Forum, Americans clock in about 1,800 hours at work per year on average, which is 468 more hours per year than workers in Germany. And many are leaving vacation time on the table, WalletHub says.

"Even when given the chance to take time off, many Americans won’t, as nearly half of workers don't expect to use all of their allotted vacation days," the report said. "It is possible to work hard without overdoing it, though. Hard work is key to success, and the residents of some states understand that better than others."

The top 10 hardest working states in America in 2026 are:

No. 1 – South Dakota
No. 2 – North Dakota
No. 3 – Alaska
No. 4 – Hawaii
No. 5 – Wyoming
No. 6 – Nebraska
No. 7 – Texas
No. 8 – New Hampshire
No. 9 – Tennessee
No. 10 – Georgia
