Generally, when children are under the age of five, educators believe that they are best suited for and interested in learning, because those are the years in which there is the strongest opportunity to build a broad and solid foundation for lifelong literacy and well-being.

That sentiment is deeply held by Collaborative for Children, the Houston-based nonprofit organization with the mission to meaningfully improve the quality of early childhood education and provide access to cutting-edge technology through its Centers of Excellence to all children, especially those in low-income and marginalized communities.

“The reason the organization was started about 40 years ago is that a group of philanthropists in the greater Houston area suggested that this was so important because 90 percent of the brain develops or grows in the time frame between ages zero to five years of age,” Melanie Johnson, president and CEO of Collaborative for Children, tells InnovationMap.

Presented on the cover of a June issue of Science, a study from Rice University engineer Aditya Mohite's lab uncovered a method to synthesize a high-efficiency perovskite solar cell, known as formamidinium lead iodide (FAPbI3), converting them into ultrastable high-quality photovoltaic films, according to a statement from Rice. Photovoltaic films convert sunlight into electricity.

The new process makes solar cells that are about 10 times more durable than traditional methods.

“Right now, we think that this is state of the art in terms of stability,” Mohite said in a statement. “Perovskite solar cells have the potential to revolutionize energy production, but achieving long-duration stability has been a significant challenge.” Read more.

Houston-based e-commerce software and services company Cart.com has hired a former Shopify executive as its chief people officer.

Before joining Cart.com, Lani Doyle was chief HR officer at Strategic Solutions Group, a provider of health care software.

Prior to that, Doyle was head of talent development and operations at Shopify, an e-commerce platform for businesses that posted revenue of $7.1 billion in 2023.

Cart.com is one of the fastest-growing companies in commerce today, and I’m excited to partner with our teams to help drive growth and scalability,” Doyle says in a news release. “I am eager to contribute to shaping our culture and developing programming that supports and elevates high-performing teams, ensuring we achieve our ambitious goals.”

Omair Tariq, founder and CEO of Cart.com, describes Doyle as a “strategic leader” who will help develop the startup’s continually growing team. The company, founded in 2020 in Houston, employs more than 1,600 people.

“Her deep expertise in HR strategy and talent development will be instrumental as we accelerate our growth trajectory and foster a dynamic workplace culture,” says Frank Parker, chief operating officer of Cart.com.

In February, Cart.com made another high-level executive move by promoting Joe Barth from senior vice president of fulfillment to chief logistics officer.

Cart.com has more than 6,000 customers. The company handles more than 75 million orders per year from 14 fulfillment centers in the U.S.

Earlier this year, Tariq joined the Houston Innovators Podcast to share a bit about his company's growth and its relocation from Austin back to Houston.

"I think Austin served its purpose. It certainly allowed us to be in the limelight in all the right ways, and I'm grateful for it," Tariq says on the show. "But once we got to a point, once we closed our series C round and became a unicorn ... I think we're now at a scale where the infrastructure that Houston provides is probably something that will be more attractive and useful for us in the long term."

University of Houston debuts UH Health, expanding collaborative health care and research efforts

health care hub

The University of Houston has announced its cross-disciplinary academic venture, UH Health.

It will align UH’s efforts in education, research and clinical partnerships to create new opportunities to advance research and innovation, community impact, and education, according to a news release.

“From opening the state’s first college of optometry to developing groundbreaking vaccines, improving the health of all Texans has been a UH priority for decades,” UH President Renu Khator said in the release. “Now, with the launch of UH Health, we are bringing together the full strength of our health enterprise to expand our reach, advance research and transform the future of health for our communities.”

UH is adopting a fully collaborative model, with health professionals from various concentrations to help better understand overall patient care, which includes factors like clinical, behavioral and social factors that can influence health outcomes.

UH Health will also have partnerships with HCA Healthcare, Memorial Hermann Hospital, Baylor College of Medicine, MD Anderson Cancer Center and other Texas Medical Center facilities. In addition, UH Health will work with DHR Health in the Rio Grande Valley to create new opportunities for health care education, workforce development and research in one of Texas' medically underserved regions.

As part of UH Health, UH Health Family Care Center will provide integrated primary care and mental health services to the University and its surrounding communities at affordable prices to serve the Third Ward, East End and South Houston. The Household-Centered Care program will give students opportunities to work directly with community caregivers through patient home visits, while the 3rd Ward Place of Wellness offers health screenings, preventive services, education and other resources designed to support long-term health and well-being, according to UH. The College of Optometry will continue to see children and families via outreach programs and clinics across the community.

UH Health also aims to address shortages in health care professionals, providing a pipeline from the university to the workforce. According to the Texas Hospital Association, 64 percent of hospitals in the state are operating with reduced services and fewer beds due to staff shortages.

“Preparing the next generation of health care leaders is one of the most important investments we can make in the future of our state,” Jonathan McCullers, vice president for health affairs at UH and dean of the Tilman J. Fertitta Family College of Medicine at UH, added in the release. “UH Health is ensuring our graduates are equipped to work effectively in today’s complex healthcare environment.”

Additionally, UH shared it is investing $77 million into a 55,000-square-foot medical research facility aimed at boosting interdisciplinary research and scientific discovery.

“Healthcare is no longer delivered in isolation, and complex health challenges require coordinated solutions,” McCullers added. “UH Health allows us to work across disciplines to tackle health challenges, advance research and improve outcomes for patients and our community.”

Report: Houston ranks among 10 most affordable metros to raise a child

Family Matters

Raising a child is not an easy or inexpensive feat, but a new study has determined Houston parents have the 7th lowest childrearing costs in the country.

SmartAsset's new report, "Cost of Raising a Child in Major U.S. Metros – 2026 Study," calculated year-over-year changes in the annual cost of raising a child (factoring in childcare, additional housing costs, food, transportation, medical costs and other necessities) in the 48 largest U.S. metro areas. MIT's Living Wage Calculator was used to compare the living costs of a household with two working adults and one child to that of a childless household with two working adults.

Childrearing costs in Houston-Pasadena-The Woodlands have grown 3.37 percent since last year, totaling $22,605 for a family of three in 2026. That's $737 more than what it took to raise a child in 2025 and $1,209 higher than in 2024.

This is how SmartAsset broke down the annual cost for raising a child in the Houston area:

  • Cost of childcare: $10,265
  • Cost of food: $1,721
  • Other expenses: $10,619

Houston ranked 42nd in SmartAsset's national list of cities with the highest childrearing costs in 2026, making it the No. 7 most affordable U.S. metro.

San Francisco-Oakland-Fremont in California topped the list with the highest childrearing costs in the U.S., at $43,171. The cost for raising a child in this California metro soared nearly 11 percent higher since last year.

Memphis, Tennessee ranked dead last as the most affordable U.S. metro for raising a child in 2026. Families will spend less than $20,000 to raise a child in Memphis, only 3.24 percent more than what was needed in 2025.

Raising a child in other Texas metros
It may come as no surprise that Austin is the most expensive place to raise a child in Texas, and it appeared as the 31st most expensive U.S. metro for families. Parents will spend nearly $25,000 to raise a child in the state's capital city, which is $703 higher than it was a year ago.

Two other Texas metros join Houston among the top 10 most affordable U.S. metros for raising a family: San Antonio-New Braunfels (No. 3) and Dallas-Fort Worth-Arlington (No. 10). Childrearing costs in San Antonio add up to $21,393 annually, and Dallas-Fort Worth parents will spend $23,340 to raise their children in 2026.

The top 10 most affordable U.S. metros for raising a child in 2026 are:

  • No. 1 – Memphis, Tennessee ($19,922)
  • No. 2 – Nashville, Davidson-Murfreesboro-Franklin, Tennessee ($21,216)
  • No. 3 – San Antonio-New Braunfels ($21,393)
  • No. 4 – Birmingham, Alabama ($21,684)
  • No. 5 – Virginia Beach-Chesapeake-Norfolk, Virginia ($22,314)
  • No. 6 – Atlanta-Sandy Springs-Roswell, Georgia ($22,470)
  • No. 7 – Houston-Pasadena-The Woodlands ($22,605)
  • No. 8 – Richmond, Virginia ($22,658)
  • No. 9 – Louisville/Jefferson County, Kentucky ($23,270)
  • No. 10 – Dallas-Fort Worth-Arlington ($23,340)

Axiom Space expands executive team with two C-suite hires

new leaders

Fresh off officially making Texas its legal headquarters, Axiom Space has named two new C-level executives.

The Houston-based spacetech company, which is developing the first commercial space station, announced earlier this month that it had appointed Zach Gitomer as its new chief financial officer and Erick Wegerer as chief information officer.

Gitomer served as vice president of investor relations and capital markets for Axiom from March to June of this year. Before joining Axiom, he held various leadership roles at Bank of America, Merrill Lynch, and Citi, where he supported technology and growth companies, according to Axiom.

"Building era-defining space infrastructure and pioneering the orbital economy is a complex endeavor that requires not just an audacious vision and stellar engineering talent, but the financial infrastructure, discipline, and capital strategy to match," Gitomer shared in a LinkedIn post. "I’m honored to take on this role ... I’m looking forward to partnering with the exceptional leadership team here at Axiom Space during a defining chapter for the company and commercial spaceflight broadly, as well as a crucial period for maintaining U.S. human presence in low-Earth orbit and leadership in space exploration."

Wegerer joins Axiom after most recently serving as CIO of Washington-based Insitu Inc., a subsidiary of Boeing that develops customized unmanned hardware for commercial, government and defense customers.

"My time at Insitu was defined by talented people, meaningful challenges, and work that mattered. I'm grateful for the teams, partners, and leaders who made progress there possible. Stepping into Axiom, I'm energized by the mission, the momentum, and the opportunity to help shape what's next," Wegerer shared.

The duo was celebrated on the floor of the New York Stock Exchange last week.

“We are pleased to welcome these exceptional leaders to the Axiom Space team," Axiom CEO Jonathan Cirtain added in the announcement. “Their strong record of helping complex organizations advance their strategic priorities will strengthen our executive team to further advance our core business objectives."

It's been a busy summer for Axiom. The company tacked on an additional $175 million to a previously announced capital raise, bringing the oversubscribed round to a total of more than $525 million, in June.

It also announced plans to open a Japanese subsidiary July 1. It tapped veteran Japanese astronaut Koichi Wakata to lead Axiom Space Japan as chief technology officer in the Asia-Pacific region. It also shared plans to establish Axiom Space Switzerland, a wholly owned subsidiary based in Lucerne that is also expected to begin operations this summer.

Axiom also officially redomiciled its legal headquarters from Delaware to Texas last month. Read more here.
