There may come a time when you or someone you love is in need of a new pair of lungs. Or perhaps it's a liver. It's not a scenario anyone dreams of, but thanks to Houston company Volumetric, you may never end up on a waiting list. Instead, that organ is made to order and 3D printed using a mix of medical plastics and human cells.

And this possibility isn't necessarily in the distant future. On the cover of the May 3 issue of the journal Science, is a contraption that looks a bit like a futuristic beehive. It's a working air sac complete with blood vessels, the beginnings of a technology that is perhaps only a decade from being implanted in humans. And it was crafted on a 3D printer in Jordan Miller's lab at Rice University.

Yes, there are shades of another Houston story — Denton Cooley's implantation of the first artificial heart — but Cooley only inserted the organ. Miller and his bioengineering graduate student Bagrat Grigoryan are primed to profit from their inventions.

In 2018, they started Volumetric Inc., a company that sells both the hydrogel solutions used for printing organs like theirs and the printers themselves. Touring Miller's lab in the Houston Medical Center is a visual timeline of his team's progress designing printers. The version being manufactured is a slick little number, small enough to fit under chemical exhaust hoods, but fitted with everything necessary to print living tissues. It's made and sold in cooperation with CellInk, a larger bioprinting company.

"Our technology is based on projection," Miller explains. Specifically, it's stereolithography, a type of 3D printing that produces the finished product layer-by-layer. Shining colored light of the right intensity turns the polymers into a solid gel.

But why start a company when Miller and Grigoryan are already busy with research?

"If we want to do translational research, commercialization is important," reasons Miller. "We need to build the market to get that technology into the world."

Miller explains that usually the inventor of a technology is the best one to bring it to market.

"When we were building this technology in the lab we saw the potential for commercialization," he recalls. "We do see that this technology is highly scalable. We do think it can have a positive impact on tissue models in a lab."

Those tissue models could one day make not just scientists, but also animal rights activists, very happy. With the technology that Volumetric is developing, scientists could eventually print human cells so well that animal models would be far less accurate in predicting the success that the product being tested would have on humans.

As academics, though, Miller and Grigoryan weren't sure how to start a company. Fortunately, there is the National Science Foundation (NSF) and its I-Corps program. The pair spent a couple of weeks doing a regional program that taught scientists how to commercialize their technology.

"They want to see funded research get out of the lab," Miller says, explaining that they moved on to the national I-Corps program while Miller was on sabbatical from teaching at Rice, allowing them to interview potential customers.

This gave them the confidence to launch last year. Grigoryan now works full-time at the Med Center incubator and accelerator, Johnson & Johnson's JLabs. He has a team of two other scientists on staff.

"It would have been a lot harder to get started if we didn't have a space like JLabs available," Miller says. It also helps, he adds, that JLabs takes no equity, only helping the fledgling brand to finalize its market and get hooked in with potential investors.

Volumetric has its demo units ready to go and expects to start shipping printers in late June, pending final certifications.

"We believe we have technology to make organ replacements for people," Miller says.

And someday soon, long waits for a new set of lungs and a life of antirejection drugs could be a thing of the past.

Houston health orgs lost $58M in canceled, stalled NIH grants, new report shows

research cuts

Seven institutions in the Houston area have lost nearly $60 million in grants from the National Institutes of Health (NIH) that were aimed at funding health research.

The Science & Community Impacts Mapping Project identified 37 cancelled or frozen NIH grants worth $58.7 million that were awarded to seven Houston-area institutions. The University of Texas Medical Branch at Galveston suffered the biggest loss — five grants totaling nearly $44.8 million.

The Harvard University T.H. Chan School of Public Health reported in May that over the previous several months across the U.S., the federal government had terminated roughly 2,100 NIH research grants worth around $9.5 billion.

In August, the U.S. Supreme Court derailed researchers’ efforts to reinstate almost $2 billion in research grants issued by NIH, according to Nature.com.

“Make no mistake: This was a decision critical to the future of the nation, and the Supreme Court made the wrong choice. History will look upon these mass National Institutes of Health (NIH) research grant terminations with shame,” the American Association of Medical Colleges said in a statement. “The Court has turned a blind eye to this grievous attack on science and medicine, and we call upon Congress to take action to restore the rule of law at NIH.”

Texas health researchers rely heavily on NIH grants and contracts. During the federal government’s 2024 budget year, NIH awarded $1.9 billion in grants and contracts that directly supported 30,553 jobs and more than $6.1 billion in economic activity in Texas, according to the United for Medical Research coalition.

Here’s a rundown of the cancelled and frozen NIH grants in the Houston area.

  • University of Texas Medical Branch at Galveston: Five cancelled or frozen grants, totalling approximately $44.8 million in funding lost.
  • Baylor College of Medicine: 17 grants cancelled or frozen, totalling approximately $8 million in funding lost
  • University of Houston. Five cancelled or frozen grants, totalling approximately $3.7 million in funding lost
  • University of Texas Health Science Center Houston: Five grants cancelled or frozen, totaling approximately $1.1 million in funding lost.
  • University of Texas MD Anderson Cancer Center: Two grants cancelled or frozen, totalling $831,581 in funding
  • Rice University. Two grants cancelled or frozen, totaling $254,645 in funding lost
  • Prairie View A&M University: One grant cancelled or frozen, totalling $31,771 in funding lost

Magnolia milkshake shop blends up a sweet partnership with Comcast Business

Treat Takeover

Comcast Business (CB) powers businesses of every size with fast and reliable phone, mobile, internet, cybersecurity, and television services. Houston’s local CB team also stands behind entrepreneurs and small businesses, knowing they’re the heart of thriving communities: driving growth, sparking innovation, and creating jobs close to home.

Magnolia hometown favorite Chill Milkshake and Waffle Bar was the site of Comcast Business’ latest road trip to treat customers to a cool and refreshingly free treat, picking up the tab for several hours for nearly 200 customers.

“We aren’t just about products and services, we are about building partnerships in our community and playing a supporting role, it means the world to us,” says Heather Orrico, vice president of Comcast Business in Texas.

Chill Milkshakes and Waffle Bar, located at 6606 FM 1488 Rd., Suite 110 in Magnolia, opened in December 2020 and has been a Comcast Business customer for the last two years.

Who would’ve thought you’d need WiFi to serve milkshakes and waffles? Technology runs almost every part of the business.

“In a world where people rarely carry cash anymore, we have to be able to process payments electronically and promptly. Otherwise, the day stops. Nobody wants that,” says owner Jeanie Rosett. “We count on WiFi to efficiently complete transactions and guest payments, process online orders, and keep our music lively.”

It's no surprise that Chill’s array of flavors and dedication to making the perfect milkshake (along with waffles and sandwiches) have earned them the title of best milkshake in Texas by USA Today, followed by ranking sixth-best milkshake in the nation by Travel + Leisure.

Chill’s family environment creates a space where everybody can hang out, or the kids can come on their own and parents feel they are safe. “Good WiFi keeps them connected,” says store manager Laura Mabery. “We also have people who stop in with their laptop, have a hotdog and a shake while continuing to work. We live in a world that needs to be connected! You can do that at Chill-Magnolia.”

While Mabery and Rosett appreciate the upgrade in customer service and reliability that was missing from their previous service provider, they were honored and pleasantly surprised to be selected for the recent Comcast Business “take over.”

“It's reassuring to know that our internet needs are taken care of, but that Comcast Business also supports us as a hometown commodity,” says Mabery. “And a free Chill milkshake...what's not to love about that?"

Houston robotics co. unveils new robot that can handle extreme temperatures

Hot New Robot

Houston- and Boston-based Square Robot Inc.'s newest tank inspection robot is commercially available and certified to operate at extreme temperatures.

The new robot, known as the SR-3HT, can operate from 14°F to 131°F, representing a broader temperature range than previous models in the company's portfolio. According to the company, its previous temperature range reached 32°F to 104°F.

The new robot has received the NEC/CEC Class I Division 2 (C1D2) certification from FM Approvals, allowing it to operate safely in hazardous locations and to perform on-stream inspections of aboveground storage tanks containing products stored at elevated temperatures.

“Our engineering team developed the SR-3HT in response to significant client demand in both the U.S. and international markets. We frequently encounter higher temperatures due to both elevated process temperatures and high ambient temperatures, especially in the hotter regions of the world, such as the Middle East," David Lamont, CEO of Square Robot, said in a news release. "The SR-3HT employs both active and passive cooling technology, greatly expanding our operating envelope. A great job done (again) by our engineers delivering world-leading technology in record time.”

The company's SR-3 submersible robot and Side Launcher received certifications earlier this year. They became commercially available in 2023, after completing initial milestone testing in partnership with ExxonMobil, according to Square Robot.

The company closed a $13 million series B round in December, which it said it would put toward international expansion in Europe and the Middle East.

Square Robot launched its Houston office in 2019. Its autonomous, submersible robots are used for storage tank inspections and eliminate the need for humans to enter dangerous and toxic environments.
