A Rice University chemist James Tour has secured a new $12 million cooperative agreement with the U.S. Army Engineer Research and Development Center on the team’s work to efficiently remove pollutants from soil.

The four-year agreement will support the team’s ongoing work on removing per- and polyfluoroalkyl substances (PFAS) from contaminated soil through its rapid electrothermal mineralization (REM) process, according to a statement from Rice.

“This is a substantial improvement over previous methods, which often suffer from high energy and water consumption, limited efficiency and often require the soil to be removed,” Tour says. Read more.

When something is declared clean, one question invariably springs to mind: just how clean is clean?

Then it is, “What metrics decide what’s clean and what’s not?”

To answer those questions, one must abandon the subjective and delve into the scientific — and that’s where Clean Habits come in. The company has science on its side with Synbio, a patented cleaning formula that combines a unique blend of prebiotics and probiotics for their signature five-day clean.

“Actually, we are a synbiotic, which is a prebiotic and a probiotic fused together,” says Kristy Phillips, founder and CEO of Clean Habits. “And that's what gives us the five-day clean, and we also have the longest shelf life — three years — of any probiotic on the market.” Read more.

A University of Houston professor of electrical and computer engineering, Jiming Bao, is improving thermal imaging and infrared thermography with a new method to measure the continuous spectrum of light.

His innovative method involves techniques that will be used to measure and visualize temperature distributions without direct contact with the subject being photographed, according to the university. The challenges generally faced by conventional thermal imaging is addressed, as the new study hopes to eliminate temperature dependence, and wavelength.

“We designed a technique using a near-infrared spectrometer to measure the continuous spectrum and fit it using the ideal blackbody radiation formula,” Bao tells the journal Device. “This technique includes a simple calibration step to eliminate temperature- and wavelength-dependent emissivity.” Read more.

clean dream

When something is declared clean, one question invariably springs to mind: just how clean is clean?

Then it is, “What metrics decide what’s clean and what’s not?”

To answer those questions, one must abandon the subjective and delve into the scientific — and that’s where Clean Habits come in. The company has science on its side with Synbio, a patented cleaning formula that combines a unique blend of prebiotics and probiotics for their signature five-day clean.

“Actually, we are a synbiotic, which is a prebiotic and a probiotic fused together,” says Kristy Phillips, founder and CEO of Clean Habits. “And that's what gives us the five-day clean, and we also have the longest shelf life — three years — of any probiotic on the market.”

Phillips learned about the European product almost three months before the COVID-19 pandemic. She had heard of probiotics for gut health but had no idea about probiotic cleaning.

“When COVID actually hit, I went back and really started researching the manufacturer who is based in Europe and all of their pre- and probiotic cleaners,” remembers Phillips. “And I just found it to be so interesting that they were using natural probiotics from the dirt, from the soil, from Mother Earth. And they created this entire product line that they have been using for over 15 years. And they had so many clinical trials and hospital studies and university studies that were showing that these probiotic cleaners were working, and they were reducing bacteria, viruses, even viruses in air.

“Not only were they in the cleaning spray sector, but they were also already in water purification. They were in agriculture for animal house farming. They were doing a big trial in the subway station in Milan, putting the probiotics through a big HVAC system. And I just thought, there must be something here.”

Phillips was right. After reaching out to the manufacturer, she asked if they had a distributor here in the United States. They didn't.

“Since they didn’t have a distributor here in the U.S., I got the products and tried them out for myself,” says Phillips. “They were chemical-free, non-toxic and eco-friendly and after comparing them side-by-side with the commercial cleaners we all grew up with like the Lysols, bleach, and 409s, I found that the probiotic cleaners not only worked on surface areas to remove bad bacteria and germs, they continued to work for up to five full days at 100 percent.

“The commercial cleaners did kill 99.99 percent of all bacteria and germs, but they only did it for 30 minutes. And then the bacteria and germs start to grow back. And I am like, you know, nobody tells you that in their marketing. So that is what started my journey on the probiotics and creating a line to bring to the market here in the United States.”

Phillips soon realized that her goal was easier said than done.

“I think the U.S. market is one of the hardest to break into,” says the Houston native. “Trying to launch a brand-new product in the United States, in the cleaning sector, you do have to deal with the FDA and the EPA, there is a big game that you must play. And then you do go up against the big boys, like the Johnson and Johnson's of the world. Everybody is so used to chemical cleaning. And to go and try to change that industry and disrupt it, that can be tough for people.

“And at the time, I felt like it was insane because everyone was living in their house due to COVID and continuing to use commercial cleaners that are backed with chemicals. They were all breathing that in. I felt that was doing us all an injustice, especially when you have these probiotics that are natural, non-toxic, non-chemical and safe to breathe. It does change the game.”

Once Phillips noticed that she was not alone, with companies like Jessica Alba’s The Honest Company and Mrs. Meyer’s with their plant-based cleaning products, she forged full speed ahead with Clean Habits.

Now, more than three years later, her company is making a significant impact.

“I said, OK, I’m not crazy here, I must be on the right path,” says Phillips. “With people starting to recognize that there is a better way to clean, we began to get into retailers like Kroger. Right now, we are in the process of on-boarding with Walmart and are in talks with CVS, Whole Foods, and Costco.”

The biggest signal to Phillips that the word was out on Clean Habits came in the form of a potential celebrity endorsement.

“Howie Mandel, who is a certified germaphobe, reached out to us a couple of weeks ago,” says Phillips, who before her mission to clean up the world, was a producer of reality television. “We are about to do a big campaign with him and the Clean Habits line. People know Howie Mandel. So, he is definitely going to bring more awareness to our brand, which will allow us to start a big, heavy push and hopefully we can just capitalize on it and go from there.”

Moving forward, Phillips’ vision for Clean Habits will extend beyond just traditional cleaning products. She sees that she can also have an impact on the industrial and commercial side of things.

“Right now, we are doing testing in agriculture, and this is something that our manufacturers in Europe have already done and they have been extremely successful with it,” says Phillips. “The goal is to see if we could reduce the use of pesticides in farming and replace it with just misting and spraying with the probiotics.

“We already know that by incorporating the probiotics throughout water systems, that we can actually clean the water and take it back to 100 percent natural water or pure water. We can get rid of E. coli, MRSA, staph. And so, we are going to start working with the state of Texas and into animal house cleaning and farming and cleaning their water.”

Additionally, Clean Habits already has research that proves that by incorporating the probiotics, they can start eliminating the bird flu, which affected a lot of Texas chickens recently to where over 350,000 of them had to be put down.

“We’re really trying to change the faith there in agriculture,” says Phillips. “I mean, to me, it's amazing because when I first started this, I was just trying to launch some cleaning supplies, which is fantastic, but this product is so much more than a multi-purpose cleaning spray, your floor cleaner, your drain cleaner or your laundry detergent. This goes into cleaning water, which is everyone's basic right to have clean water. And the fact that we can do it by using these probiotics, to me, my little brain can't compute that part of it.

“And then when we really did start looking into the agriculture and how, by incorporating the probiotics into the animal house, the cleaning of the water, and putting it into their housing system, that we can reduce methane gas by 41 percent. That is huge. This can profoundly change and revolutionize industries. And to be a part of that, and I am so excited.”

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
