PUSH Birth Partners, a Houston-based maternal health nonprofit, is teaming up with the Harris County Public Health Department to provide doula services for over 200 pregnant people free of cost.

Jacqueline McLeeland, CEO and founder of PUSH, says the program will begin in August and aims to improve maternal health and birth outcomes for vulnerable populations. McLeeland says the organization has built up a strong doula training program through their collective in partnership with March of Dimes and several local doula organizations.

McLeeland says PUSH aims to address poor maternal health outcomes for women of color in part by training more doulas of color who can help reduce racial disparities in care. A 2021 study by Harris County Public Health found Precinct 1, which is predominantly composed of people of color, had the highest maternal mortality rate of the county.

Through their collective, PUSH has trained two cohorts of doulas through an integrated care model, focused on providing collaborative care with medical providers in the healthcare system.

“Our programs are designed to advance health equity, we see the numbers, we see that women of color, specifically Black women in that group are disproportionately impacted,” McLeeland tells InnovationMap.

After receiving a $100,000 grant from the Episcopal Health Foundation in 2023, PUSH began their doula expansion program in Houston and they have since received an additional grant from EHF for the next fiscal year. McLeeland shares PUSH has also launched a pilot program called Blossoming Beyond Birth, sponsored by the Rockwell Fund, targeted towards improving maternal mental health through weekly support groups in Houston.

“It’s very exciting to know that we have come this far from where we started and to see how everything is coming together,” McLeeland shares.

For McLeeland, improving maternal health outcomes and providing support to people experiencing high-risk pregnancies are deeply personal goals. McLeeland has sickle cell anemia, a condition that can cause serious complications during pregnancy. During her first pregnancy in 2015, McLeeland was placed on bed rest two months before her due date at which point she had been working in clinical research within the pharmaceutical industry for over 12 years.

“People don’t realize the magnitude of what women go through, during pregnancy and after,” McLeeland says. “There’s a lot of emotional, psychological, and physical tolls depending on how the pregnancy and delivery went.”

After giving birth to her first child, McLeeland took maternity leave, during which she began to research maternal morbidity and mortality trends, information which she says was not widely discussed at the time.

McLeeland says entering the maternal healthcare field felt like a necessity following her second pregnancy. Several months after giving birth to her second child, McLeeland says she received a bill for a surgical procedure that was performed during her cesarean section without her or her husband’s consent. McLeeland says that was the first time she was made aware of the surgery.

“The procedure that was claimed to have been performed could have put my life in jeopardy by hemorrhaging based off of additional research I did once, I came across that information,” McLeeland explains. “These are some of the things that happen in the healthcare system that make people skeptical of trusting in the healthcare system, trusting in doctors.”

McLeeland says the key to improving maternal and birth outcomes for vulnerable populations is to encourage the partnership between doulas, community healthcare workers, and physicians and hopes to further this collaboration through future programming.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
