This Houston neighbor is the fastest growing wealthy suburb in America

By The Numbers

The Houston-area city of Fulshear is booming like nowhere else: It's now the No. 1 fast-growing affluent suburb in the country.

Fulshear's No. 1 status was unveiled in a new GoBankingRates' study that ranked the "30 Fastest Growing Wealthy Suburbs in America" for 2025. The report examined population changes from 2018 to 2023 among cities and towns in major U.S. metro areas with populations between 25,000 and 100,000 residents. Median household income, average home value, and a "livability score" were also calculated for each locale.

Fulshear, located 34 miles west of downtown Houston, experienced the most dramatic population increase out of all 30 cities in the report. Though the suburb only has an estimated population of 42,616 residents, that number has skyrocketed 237 percent during the five-year period.

A Fulshear resident's median income is $178,398 annually, and the average value of a home in the city comes out to $521,157, the report additionally found.

Fulshear was the second fastest growing city in America in 2023. The city's growth is further reflected by the number of new apartments that were built in the area in 2024.

Texas is tops
Texas cities took the top three fastest growing U.S. suburbs for 2025, with Dallas-area cities of Celina (No. 2) and Prosper (No. 3) experiencing wildly different (yet still sky high) population changes. Celina's population ballooned 190 percent to 43,317 residents, while Prosper's grew 81 percent to an estimated 41,660 people.

Other Texas cities that earned spots in the report include Flower Mound (No. 19), Southlake (No. 27), University Park (No. 28) and Colleyville (No. 29), all in the Dallas-Fort Worth area.

"The old adage that everything is bigger in Texas is true, considering the number of Lone Star State suburbs that are quickly growing in population and overall wealth," the report's author wrote.

The top 10 fastest growing wealthy suburbs in America are:

  • No. 1 – Fulshear, Texas
  • No. 2 – Celina, Texas
  • No. 3 – Prosper, Texas
  • No. 4 – Erie, Colorado
  • No. 5 – Clarksburg, Maryland
  • No. 6 – Zionsville, Indiana
  • No. 7 – Redmond, Washington
  • No. 8 – Dublin, California
  • No. 9 – Parkland, Florida
  • No. 10 – Eastvale, California

Rice research breakthrough paves the way for advanced disease therapies

study up

Bioengineers at Rice University have developed a “new construction kit” for building custom sense-and-respond circuits in human cells, representing a major breakthrough in the field of synthetic biology, which could "revolutionize" autoimmune disease and cancer therapeutics.

In a study published in the journal Science, the team focused on phosphorylation, a cellular process in the body in which a phosphate group is added to a protein, signaling a response. In multicellular organisms, phosphorylation-based signaling can involve a multistage, or a cascading-like effect. Rice’s team set out to show that each cycle in a cascade can be treated as an elementary unit, meaning that they can be reassembled in new configurations to form entirely novel pathways linking cellular inputs and outputs.

Previous research on using phosphorylation-based signaling for therapeutic purposes has focused on re-engineering pathways.

“This opens up the signaling circuit design space dramatically,” Caleb Bashor, assistant professor of bioengineering and biosciences and corresponding author on the study, said in a news release. “It turns out, phosphorylation cycles are not just interconnected but interconnectable … Our design strategy enabled us to engineer synthetic phosphorylation circuits that are not only highly tunable but that can also function in parallel with cells’ own processes without impacting their viability or growth rate.”

Bashor is the deputy director for the Rice Synthetic Biology Institute, which launched last year.

The Rice lab's sense-and-respond cellular circuit design is also innovative because phosphorylation occurs rapidly. Thus, the new circuits could potentially be programmed to respond to physiological events in minutes, compared to other methods, which take hours to activate.

Rice’s team successfully tested the circuits for sensitivity and their ability to respond to external signals, such as inflammatory issues. The researchers then used the framework to engineer a cellular circuit that can detect certain factors, control autoimmune flare-ups and reduce immunotherapy-associated toxicity.

“This work brings us a whole lot closer to being able to build ‘smart cells’ that can detect signs of disease and immediately release customizable treatments in response,” Xiaoyu Yang, a graduate student in the Systems, Synthetic and Physical Biology Ph.D. program at Rice who is the lead author on the study, said in a news release.

Ajo-Franklin, a professor of biosciences, bioengineering, chemical and biomolecular engineering and a Cancer Prevention and Research Institute of Texas Scholar, added “the Bashor lab’s work vaults us forward to a new frontier — controlling mammalian cells’ immediate response to change.”

Greentown Labs names new CEO to lead pioneering climate tech incubator

Transition News

Houston and Boston climate tech incubator Greentown Labs has named Georgina Campbell Flatter as the organization’s incoming CEO.

Flatter will transition to Greentown from her role as co-founder and executive director of TomorrowNow.org, a global nonprofit that studies and connects next-generation weather and climate technologies with communities most affected by climate change.

“We are at a transformational moment in the energy transition, with an unprecedented opportunity to drive solutions in energy production, sustainability, and climate resilience,” Flatter said in a news release. “Greentown Labs is, and has always been, a home for entrepreneurs and a powerhouse of collaboration and innovation.”

Previously, Flatter worked to launch TomorrowNow out of tomorrow.io, a Boston-based AI-powered weather intelligence and satellite technology company. The organization secured millions in climate philanthropy from partners, including the Gates Foundation, which helped deliver cutting-edge climate solutions to millions of African farmers weekly.

Flatter also spent 10 years at the Massachusetts Institute of Technology (MIT), where she was a senior lecturer and led global initiatives at the intersection of technology and social impact. Her research work includes time at Langer Lab and Sun Catalytix, an MIT – ARPA-E-funded spin-out that focused on energy storage solutions inspired by natural photosynthesis. Flatter is also an Acumen Rockefeller Global Food Systems Fellow and was closely involved with Greentown Labs when it was founded in Boston in 2011, according to the release.

“It’s rare to find an individual who has impressive climate and energy expertise along with nonprofit and entrepreneurial leadership—we’re fortunate Georgie brings all of this and more to Greentown Labs,” Bobby Tudor, Greentown Labs Board Chair and Chairman of the Houston Energy Transition Initiative, said in a news release.

Flatter will collaborate with Kevin Dutt, Greentown’s Interim CEO, and also continue to serve on Greentown’s Board of Directors, which was recently announced in December and contributed to a successful $4 million funding round. She’s also slated to speak at CERAWeek next month.

“In this next chapter, I’m excited to build on our entrepreneurial roots and the strength of our ever-growing communities in Boston and Houston,” Flatter added in a news release. “Together, we will unite entrepreneurs, partners, and resources to tackle frontier challenges and scale breakthrough technologies.”

Greentown also named Naheed Malik its new chief financial officer last month. The announcements come after Greentown’s former CEO and president, Kevin Knobloch, announced that he would step down in July 2024 after less than a year in the role.
