Kirsten Siebach is getting ready for her Mars mission — one that keeps her firmly planted on Earth, but will allow her to search for ancient microbial life on the Red Planet nonetheless. The Rice University professor has again been selected by NASA to join a research team overseeing a rover that is currently en route to Mars.

"Because there is only one rover, the whole team at NASA has to agree about what to look at, or analyze, or where to drive on any given day," Siebach says in the release. "None of the rovers' actions are unilateral decisions. But it is a privilege to be part of the discussion and to get to argue for observations of rocks that will be important to our understanding of Mars for decades." Read more.

Mike Francis wants to fireproof the state of California. It's a lofty goal, but he has the means. His company, NanoTech Inc., has an innovative product that can insulate and fireproof materials, and, buoyed by a $5 million seed round, he's well on his way to being able to slowly but surely fireproof existing infrastructure in the West Coast.

"We're working with all of the major players in the state of California to not only fireproof the utility infrastructure, but eventually homes and businesses," Francis says on last week's episode of the Houston Innovators Podcast. "Our goal, if we're looking into the future, is to fireproof that state — and we're working with the right people and companies to make it happen." Read more and listen to the podcast.

Nowadays, consumers care about where their products come from — and if they exist due to a humanitarian or sustainable supply chain — and the onus is on businesses to increase transparency. That's where Topl, a Houston-based blockchain company, and its new partner Trackz, a Denver-based supply chain software company, come in.

"Topl and TrackX's solution will be a great option for companies having to comply with new regulations and compliance mandates," says Kim Raath, CEO of Topl. "Further, our joint solution allows users to visualize their supply chain data, monitor suppliers, and easily report the progress of ESG initiatives to all stakeholders."

A Rice University Martian geologist has been chosen by NASA as one of the 13 scientists who will be working on a new Mars rover.

Perseverance, the rover that launched in July and is expected to land on Mars in February. It will be scouting for samples to bring back to study for ancient microbial life, and Kirsten Siebach — an assistant professor of Earth, Environmental and Planetary Sciences — will be among the researchers to work on the project. Her proposal was one of 119 submitted to NASA for funding, according to a Rice press release.

"Everybody selected to be on the team is expected to put some time into general operations as well as accomplishing their own research," she says in the release. "My co-investigators here at Rice and I will do research to understand the origin of the rocks Perseverance observes, and I will also participate in operating the rover."

Perseverance is headed for Jezero Crater, a 28-mile-wide area that once hosted a lake and river delta where, according to scientists, microbial life may have existed over 3 billion years ago. Siebach is particularly excited hopefully find fossils existing in atmospheric carbon dioxide dissolved in water — which usually exists as limestone on Earth.

"There are huge packages of limestone all over Earth, but for some reason it's extremely rare on Mars," she says. "This particular landing site includes one of the few orbital detections of carbonate and it appears to have a couple of different units including carbonates within this lake deposit. The carbonates will be a highlight of we're looking for, but we're interested in basically all types of minerals."

Siebach is familiar with rovers — she was a member of the team for NASA's Curiosity rover, which has been exploring Mars since 2012. For this new rover, Siebach knows what to expect.

"Because there is only one rover, the whole team at NASA has to agree about what to look at, or analyze, or where to drive on any given day," Siebach says in the release. "None of the rovers' actions are unilateral decisions. But it is a privilege to be part of the discussion and to get to argue for observations of rocks that will be important to our understanding of Mars for decades."

Siebach and her team — which includes Rice data scientist Yueyang Jiang and mineralogist Gelu Costin — are planning to tap into computational and machine-learning methods to map out minerals and discover evidence for former life on Mars. They will also be using a Planetary Instrument for X-ray Lithochemistry, or PIXL, to analyze the materials.

The return mission isn't expected to return until the early 2030s, so it's a long game for the scientists. However, the samples have the potential to revolutionize what we know about life on Mars with more context than before.

"Occasionally, something hits Mars hard enough to knock a meteorite out, and it lands on Earth," she says in the release. "We have a few of those. But we've never been able to select where a sample came from and to understand its geologic context. So these samples will be revolutionary."

Houston claims 19% of Texas’ new live-work-play growth

by the numbers

In Texas, Houston is a big player in the live-work-play real estate movement.

A new 21-city analysis from coworking marketplace CoworkingCafe shows the Houston area added five live-work-play projects—mixed-use developments with residential, office and recreational components—over the past decade.

From 2016 to 2025, Houston accounted for 19 percent of Texas’ new live-work-play inventory, the analysis shows. Among the new local developments were Arrive Upper Kirby, St. Andrie, and The Laura:

  • Arrive Upper Kirby, which was sold in 2021 for $182 million, offers more than 61,000 square feet of retail and restaurant space adjacent to apartments and offices. The 13-story, 265,000-square-foot project was completed in 2017.
  • St. Andrie, a 32-acre, mixed-use community, was completed in 2019. The apartment-anchored development includes an H-E-B grocery store and 37,000 square feet of office space.
  • The Laura, spanning 110,000 square feet, was completed in 2023. Among the apartment complex’s amenities is a coworking space.

According to Northspyre, a software provider for real estate developers, live-work-play projects enable people to meet their needs, such as housing, workplaces, stores, restaurants, and recreation facilities, in a single place.

A total of 542 live-work-play developments opened between 2016 and 2025 in the 21 cities, with another 69 in the pipeline for 2026, CoworkingCafe says. Among major markets, New York City made up the largest share (119) of new live-work-play developments from 2016 to 2025.

The Houston area’s five projects were built in 2018, 2019, 2020, 2024, and 2025, CoworkingCafe data indicates, with another project scheduled for completion next year. The Greater Houston Partnership recently highlighted four mixed-use projects taking shape in the region, but only one of them is scheduled to be finished in 2027. It can take two to five years or more to complete a mixed-use development.

Of the five Houston developments finished in the past decade, 56 percent of the space went toward multifamily units, 29 percent toward offices, and 16 percent toward retail, CoworkingCafe says.

As noted by the Houston-Galveston Area Council, economic development in the 21st century “is about cultivating quality live-work-play environments that attract, retain, and grow a diverse and skilled population. Employers and businesses are increasingly choosing to make long-term investments in places that connect and engage people to strengthen economic competitiveness and promote innovation.”

With eight completed projects, Austin led construction of live-work-play developments in Texas from 2016 to 2025, according to CoworkingCafe. Dallas, which welcomed five live-work-play developments during that period, tied with Houston. San Antonio data wasn’t available.

Here's the income it takes to live comfortably in Houston in 2026

Money Talk

2026 report analyzing how much it costs to live "in sustainable comfort" in the biggest U.S. cities has found Houston residents have the 11th lowest salary requirement to live a comfortable life in 2026.

SmartAsset's annual report found single adult residents in Houston need to make $89,981 a year to qualify as "financially stable." Compared to last year, single Houstonians needed to make $83 more to live comfortably in the city.

Families with two working parents and two children need to make a household income of $204,672 to have a financially stable life in Houston, the report found. That's almost $2,000 less than what families needed to make last year.

To determine the rankings, SmartAsset's analysts examined 100 of the largest U.S. cities and used the latest cost of living data – such as the costs for housing, food, transportation, and income taxes where applicable – from the MIT Living Wage Calculator for childless individuals and for two working adults with two children.

For the purpose of the study, the 50/30/20 budgeting strategy was used to determine "comfortable lifestyle" costs for both individuals and families: 50 percent of income to cover needs and living expenses, 30 percent for "wants," and 20 percent for savings or paying down debt.

Here's breakdown of a Houston resident's comfortable lifestyle based on SmartAsset's findings:

  • $44,991 dedicated to needs and living expenses
  • $26,994 dedicated to wants
  • $17,996 dedicated to savings or debt repayment

This is SmartAsset's interpretation of a comfortable lifestyle for families of four:

  • $102,336 dedicated to needs and living expenses
  • $61,402 dedicated to wants
  • $40,934 dedicated to savings or debt repayment
SmartAsset said single individuals and families should compare the fluctuating local cost of living and their long-term goals to fully "understand the context" of their respective household incomes. But it's worth pointing out that a financially stable life in Houston isn't quite attainable for many residents: The city had a median household income of $64,361 in 2024, according to the U.S. Census Bureau.

Comfortable salaries in other Texas cities

Elsewhere in Texas, the report found that families in the Dallas-Fort Worth suburbs Frisco and McKinney "are closest to a comfortable salary."

"In Frisco, the median household earns $145,444 – substantially higher than the national median of $83,730," the report's author wrote. "This figure also accounts for 63.1 percent of the $230,464 income a family of four in Frisco needs to live comfortably. In McKinney, TX, the $124,177 median household income accounts for 53.9 percent of the $230,464 needed."

Both cities also tied with Plano for the 29th highest salary needed nationally to live comfortably in 2026. Single adults living in these cities need to make $109,242 a year to live a financially stable life this year.


On the opposite end, San Antonio has the lowest salaries needed to live comfortably in the U.S. Single adults only need to make $83,242 a year, and $192,608 for families of four.
