Houston-based PolyVascular, which develops minimally invasive solutions for children with congenital heart disease, was named the overall winner of the American Heart Association’s annual Health Tech Competition earlier this month.

The company was founded in 2014 by Dr. Henri Justino and Daniel Harrington and was part of TMCi's 2017 medical device cohort. It is developing the first polymer-based transcatheter pulmonary valve designed specifically for young children, allowing for precise sizing and redilation as the child grows while also avoiding degradation. PolyVascular has completed preclinical studies and is working toward regulatory submissions, an early feasibility study and its first-in-human clinical trial thanks to a recent SBIR grant from the National Heart, Lung, and Blood Institute.

With the new AHA honor, PolyVascular will be invited to join the association’s Center for Health Technology & Innovation Innovators’ Network, which connects entrepreneurs, providers and researchers to share and advance innovation in cardiovascular and brain health.

“This is a tremendous honor for PolyVascular—we’re especially proud to bring hope to families and children living with congenital heart defects,” Justino said in a news release. “Our technology—a minimally invasive valve that can be expanded over time to grow with the child—has the potential to dramatically reduce the need for repeated open-heart surgeries.”

The Health Tech Competition is a live forum for health care innovators to present their digital solutions for treating or preventing cardiovascular diseases and stroke.

Finalists from around the world addressed heart failure, hypertension, congenital heart defects and other issues that exist in cardiovascular, brain and metabolic health. Solutions were evaluated on the criteria of validity, scientific rigor and impact.

The judges included Texas-based Dr. Eric D. Peterson, professor of medicine in the division of cardiology at UT Southwestern Medical Center, and Dr. Asif Ali, clinical associate professor of cardiovascular medicine at the University of Texas Medical School in Houston and director at Cena Research Institute.

According to the American Heart Association, nearly half of U.S. adults live with some form of cardiovascular disease or stroke.

“The American Heart Association plays a pivotal role in advancing innovative care pathways, and we’re excited that our solution aligns with its guidelines and mission,” Justino said in a news release. “It’s time these life-changing technologies reach the youngest patients, just as they already do for adults.”

University of Houston receives funding to support diverse cardiovascular researchers

pumping up innovation

University of Houston professors have received a nearly $800,000 grant to create a new summer program that will support diverse future researchers.

The National Heart, Lung, and Blood Institute provided $792,900 in grant funding to Bradley McConnell, professor of pharmacology at the UH College of Pharmacy, and Tho Tran, research assistant professor of chemistry at the UH College of Natural Sciences and Mathematics.

The funding will go toward created a summer program called the University of Houston Cardiovascular Undergraduate Research Experience, or UH-CURE. Ten undergraduate students per year will be selected for five years in cardiovascular research across disciplinary lines.

"We are so grateful to be able to provide talented students across the U.S. an opportunity to experience our excellent cardiovascular research environment,” Tran says in a news release. “We want UH-CURE participants to gain confidence in their research abilities through our hands-on approach and the skillset to navigate future challenges through our professional training.”

The goal is to increase students’ interest in cardiovascular research, and students have the opportunity to receive a $6,000 stipend, travel to a globally recognized cardiovascular research conference, and take part in on-campus housing and a food allowance. The summer program will also try to develop research skills, increase awareness of transdisciplinary research, promote diversity and collaborations, cultivate transferable skills necessary for succeeding in graduate school and help facilitate undergraduate students to pursue further training in cardiovascular research.

The program will integrate students into a research lab where they will learn research skills, data analysis, and research integrity. The program will be under the mentorship of a faculty member from across UH’s colleges, and include workshop and enrichment activities.

McConnell and Tran previously formed the American Heart Association-funded UH-HEART pilot program, which focused on cardiovascular research. They expanded on that initiative with UH-CURE, which includes cardiovascular research across disciplinary lines from community engagement and population-based research to basic, translational, and applied research. UH-CURE also helps prepare for careers in cardiovascular research.

“We all know that a diverse environment leads to a much better generation of ideas and solutions,” Tran adds. “We hope to bring that strength to the future of cardiovascular research through our students.”

Innovative Houston urban farm scores national award for green work

to the moon

A Houston urban farm has earned national recognition for its innovative approach to water conservation. Moonflower Farms won the American Heart Association's Foodscape Innovation Excellence Award, which recognizes positive changes in the foodscape, a term for all of the places where food is produced, purchased, or consumed.

The Heart Association selected Moonflower's submission, titled "Sustainable Farming Through Water Conservation," from 26 entries. Dallas' Restorative Farms earns the Foodscape Innovation Consumer Choice Award.

"These two innovations demonstrate a way of producing food that promotes affordability and equitable access, and the American Heart Association is proud to recognize these efforts," AHA chief medical officer for prevention Eduardo Sanchez said in a release.

Located in a 20,000-square-foot greenhouse south of downtown, Moonflower operates what it describes as Houston's first vertical indoor farm. The method both reduces the amount of space needed to grow the farm's microgreens, lettuces, herbs and edible flowers and it eliminates the disruptions caused by adverse weather conditions, which allows the farm to produce year round.

Moonflower uses a closed-loop system for capturing rainwater to feed its crops. The water is treated and oxygenated so that it can be reused. Not having to pay for water from the City of Houston allows the farm to operate more economically and sell its produce at an affordable price to restaurants and individuals.

"Our hydroponic farm uses 90-percent less water than conventional farms," Moonflower founder and CEO Federico Marques said in a statement. "We provide year-round produce to residents in historically underserved communities and donate produce to local charitable food systems."

One of those charities is Houston non-profit Second Servings, which "rescues" food from restaurants and events and distributes it to food pantries and other resources.

"The donations we receive from Moonflower Farms are incredible," Second Servings founder and president Barbara Bronstein said. "Their hydroponically grown greens are so appreciated by the needy Houstonians we serve, who lack affordable, convenient access to fresh produce."

Recently, Moonflower introduced a SupaGreens subscription box that allows customers to purchase greens weekly, bimonthly, or monthly. The box is delivered directly to consumers.

Uber rolls out women-only ride preferences to Houston users

Women Preferences

Houston women riders and drivers can now be matched to other women on the Uber app. The ride-hailing giant has expanded its pilot program nationwide in response to customer safety concerns.

“When women riders and drivers told us they wanted more control over how they ride and earn, we listened,” wrote Uber in a blog post announcing the move. “That feedback led to Women Preferences, features designed to give women the choice to ride with other women. Since our first pilots last summer, we’ve heard just how much that choice matters — from feeling more comfortable in the back seat to more confident behind the wheel.”

According to Uber, passengers can request to be matched with a woman driver by requesting an on-demand ride, scheduling a trip in advance, or setting a preference within the ride app. If wait times are longer than anticipated, the rider can opt to be paired with a driver of any sex.

Uber says it began offering the rides in 2019, after women in Saudi Arabia gained the right to drive. Since then, it has rolled out the program in Europe, Latin America, Australia, and Africa — although in some countries, only drivers can make the match.

The move forward on Women Preferences comes despite a pair of lawsuits aimed at Uber and its main competitor, Lyft. According to Time reporting, the plaintiff’s lawyers argue that women-only rides unfairly limit the volume of rides for male drivers and reinforce gender stereotypes about men.

Lyft rolled out its similar program, Women + Connect, in 2023. The initiative is slightly more expansive than Uber’s preferences, allowing both women and nonbinary people to participate.

6 Houston entrepreneurs land on coveted Inc. Female Founders 500 list

the future is female

Six Houston female entrepreneurs and innovators were named to the 2026 Female Founders 500 list.

The annual list compiled by Inc. Magazine recognizes female founders based in the U.S. who have built businesses that have moved their industries forward. The group collectively generated approximately $12.3 billion in 2025 revenue and $12.2 billion in funding to date, according to Inc. Five Houstonians were named to the list last year.

"Each year, we are increasingly amazed by the extraordinary leaders on our Inc. Female Founders 500 list," Bonny Ghosh, editorial director at Inc., said in a news release. "The honorees on this year's list include innovators in AI, beauty and wellness trendsetters winning devoted fans, and nonprofit leaders making a real impact in their communities. Together, they're showing all of us what trailblazing female leadership looks like."

The Houston founders are:

  • Sassie Duggleby, CEO and co-founder of Houston space tech and engine company Venus Aerospace. Duggleby also serves on the Texas Space Commission board of directors.
  • Stephanie Murphy, CEO and executive chairman of Aegis Aerospace, which provides space services, spaceflight product development, and engineering services. Murphy also serves as chair of the Texas Aerospace Research and Space Economy Consortium Executive Committee.
  • Laureen Meroueh, CEO and founder of Hertha Metals, which has developed a cost-effective and energy-efficient process that converts low-grade iron ore of any format directly into molten steel or high-purity iron in a single step.
  • LaToshia Norwood, managing partner of L'Renee & Associates (LRA), a full-service project management consulting firm.
  • Lauren Rottet, president and founding principal of Rottet Studio, an international architecture and design firm focused on corporate, lifestyle and hospitality projects
  • Nina Magon, founder and CEO of Nina Magon Studio / Nina Magon Consumer Products, a residential and commercial interior design company. She also co-founded KA Residences earlier this year.

"Grateful to be recognized again on the Inc. Female Founders 500," Duggleby said in a LinkedIn post. "The best part of building Venus Aerospace has been working with an incredible team pushing the boundaries of flight—and helping bring more women into aerospace along the way.

Meroueh, whose company emerged from stealth last year, voiced a similar push for bringing more women into the fold.

"We've seen a 7x jump in female-led IPOs over the last decade, from just two in 2014 (less than 1% of all IPOs) to 14 in 2024 (nearly 9% of all IPOs). Progress is happening," Meroueh shared in a LinkedIn post. "Yet, less than 1% of venture funding in hard tech goes to female-founded companies. But as my friend Ana Kraft says, the right man for the job may be a woman."

Twenty-nine Texas female founders made this list, including Amber Venz Box, founder of the Dallas-based LTK shopping platform, and Cheryl Sew Hoy, CEO and founder of Austin-based Tiny Health, a fast-growing at-home microbiome health platform. See the full list of winners here.

NASA clears Artemis moon rocket for April launch with 4 astronauts

3, 2, 1...

NASA has cleared its moon rocket on for an April launch with four astronauts after completing the latest round of repairs.

The 322-foot (98-meter) rocket will roll out of the hangar and back to the pad at Florida's Kennedy Space Center, leading to a launch attempt as early as April 1. It will mark humanity's first trip to the moon in more than 50 years.

The Artemis II crew should have blasted off on a lunar flyaround earlier this year, but fuel leaks and other problems with the Space Launch System rocket interfered.

Although NASA managed to plug the hydrogen fuel leaks at the pad in February, a helium-flow issue forced the space agency to return the rocket to the Vehicle Assembly Building for repairs, bumping the mission to April.

The space agency has only six days at the beginning of April to launch before standing down until April 30 into early May.

"It's a test flight and it is not without risk, but our team and our hardware are ready,” NASA's Lori Glaze told reporters at the end of the two-day flight readiness review.

Glaze and other NASA officials declined to provide the risk probabilities for the upcoming mission.

History has shown that a new rocket has essentially a 50% chance of success, said John Honeycutt, chair of the mission management team.

There's so much gap since the only other SLS flight — more than three years ago without anyone on board — that it's difficult to understand any risk assessment numbers, Honeycutt said.

“It's not the first flight," Glaze said. "But we're also not in a regular cadence. So we definitely have significantly more risk than a flight system that's flying all the time.”

Late last month NASA's new administrator, Jared Isaacman, announced a major overhaul of the Artemis program to speed things up and, by doing so, reduce risk.

Dissatisfied with the slow pace and lengthy gaps between lunar missions, he added an extra practice flight in orbit around Earth for next year. That is now the new Artemis III, with the moon landing by two astronauts shifted to Artemis IV. Isaacman is targeting one and maybe even two lunar landings in 2028.

NASA's Office of Inspector General warned in an audit that the space agency needs to come up with a rescue plan for its lunar crews. Landing near the moon's south pole will be riskier than it was for the Apollo astronauts closer to the equator given the rough polar terrain, according to the report.

The report cited the lunar landers as the top contributor for potential loss of crew during the first few Artemis moon landings. It listed the space agency’s loss-of-crew threshold at 1-in-40 for lunar operations and 1-in-30 for Artemis missions overall.

Contracted by NASA to provide the moon landers for astronauts, Elon Musk's SpaceX and Jeff Bezos' Blue Origin have accelerated work in order to meet the new 2028 target date. The inspector general's office said many technical challenges remain including refueling their landers in orbit around Earth before flying to the moon.

NASA sent 24 astronauts to the moon during Apollo, 12 of whom landed on it. All but one of the moonshots — Apollo 13 — achieved their prime objectives. The program ended with Apollo 17 in 1972.
