Stan Watowich's conversation flits with ease from restaurants to solving the homeless crisis. His active mind has made him a serial inventor. But the founder and current CEO of Ridgeline Therapeutics, a spin-off company of the University of Texas Medical Branch in Galveston where he is an associate professor of biochemistry and molecular biology, also has a razor-sharp focus when it comes to discussing his research. He wants to make it clear that he is not going to cure aging.

"You and I are still going to get old," he says. "But we have our hopes that as we get old our muscles will stay healthy."

He's talking about the drug candidate, RLT-72484. It has been shown to reactivate muscle stem cells and regenerate skeletal muscle in aged laboratory mice. We've all seen it in elderly humans: Your grandparents are shrunken from their younger selves because their muscles no longer regenerate at the rate that they once did.

"When you go to the gym, you feel that burn which indicates that you have muscle damage. Your stem cells are responsible for repairing this damage and building your muscles," Watowich explains. Stem cells simply don't repair at the same rate in older individuals.

That's why, for example, elderly people who break a hip often fare poorly in the aftermath. It's not uncommon to face a difficult period of physical therapy following hip fracture surgery. Many patients do not return to independent living. And, the mortality rate one year after a hip fracture can be as high as 30 percent. If RLT-72484 proves to work as well in humans as it does in animal models, it could make it easier for patients to gain muscle after a fall.

But even for healthy older adults, muscle decline can cause problems. Travel is difficult if you don't have the muscle strength for long walks. Playing with grandchildren is a challenge if your mobility is compromised. Watowich's vision is to prevent muscle decline or at least slow it down.

The drug could also potentially help muscular dystrophy patients. The genetic diseases identified under that umbrella diagnosis all cause muscle loss before old age, sometimes even in infancy. If RLT-72484 fulfills its promise, it could allow MD patients to live more normal lives.

In the University of Texas Medical Branch study, the mice's muscle fiber doubled in size while muscle strength increased by 70 percent. The team published a study last month describing its results. The next year will be spent on studies necessary to win FDA approval to begin testing on humans.

Muscle loss isn't the only big problem Ridgeline Therapeutics is seeking to address. Obesity-linked diabetes is also in Watowich's sights. His team has come up with a small molecule that shrinks fat tissue in obese animals. In studies published last year, mice lost seven percent of their body weight in 10 days of treatment without changing their diets. The animals remained obese, but their fat deposits had decreased in size by 30 percent. The drug on its own cannot make obese people thin, but it may help diabetics to return to a non-diabetic state.

Ridgeline Therapeutics is based in the Texas Medical Center. Watowich explains that 98 percent of biotech companies fail, so it's his goal to "stay lean" and use the $4.2 million award the company received from the Department of Defense to get their technologies into human trials. The company will likely move to the Johnson & Johnson Innovation Labs collaboration space in the next few months.

But of course, what Ridgeline Technologies has to offer is most exciting of all. Remember, it's not going to allow you beat aging. But someday it may well help you to live without muscle loss or diabetes.

Axiom Space wins NASA contract for fifth private mission, lands $350M in financing

ready for takeoff

Editor's note: This story has been updated to include information about Axiom's recent funding.

Axiom Space, a Houston-based space infrastructure company that’s developing the first commercial space station, has forged a deal with NASA to carry out the fifth civilian-staffed mission to the International Space Station.

Axiom Mission 5 is scheduled to launch in January 2027, at the earliest, from NASA’s Kennedy Space Center in Florida. The crew of non-government astronauts is expected to spend up to 14 days docked at the International Space Station (ISS). Various science and research activities will take place during the mission.

The crew for the upcoming mission hasn’t been announced. Previous Axiom missions were commanded by retired NASA astronauts Michael López-Alegría, the company’s chief astronaut, and Peggy Whitson, the company’s vice president of human spaceflight.

“All four previous [Axiom] missions have expanded the global community of space explorers, diversifying scientific investigations in microgravity, and providing significant insight that is benefiting the development of our next-generation space station, Axiom Station,” Jonathan Cirtain, president and CEO of Axiom, said in a news release.

As part of Axiom’s new contract with NASA, Voyager Technologies will provide payload services for Axiom’s fifth mission. Voyager, a defense, national security, and space technology company, recently announced a four-year, $24.5 million contract with NASA’s Johnson Space Center in Houston to provide mission management services for the ISS.

Axiom also announced today, Feb. 12, that it has secured $350 million in a financing round led by Type One Ventures and Qatar Investment Authority.

The company shared in a news release that the funding will support the continued development of its commercial space station, known as Axiom Station, and the production of its Axiom Extravehicular Mobility Unit (AxEMU) under its NASA spacesuit contract.

NASA awarded Axiom a contract in January 2020 to create Axiom Station. The project is currently underway.

"Axiom Space isn’t just building hardware, it’s building the backbone of humanity’s next era in orbit," Tarek Waked, Founding General Partner at Type One Ventures, said in a news release. "Their rare combination of execution, government trust, and global partnerships positions them as the clear successor-architect for life after the ISS. This is how the United States continues to lead in space.”

Houston edtech company closes oversubscribed $3M seed round

fresh funding

Houston-based edtech company TrueLeap Inc. closed an oversubscribed seed round last month.

The $3.3 million round was led by Joe Swinbank Family Limited Partnership, a venture capital firm based in Houston. Gamper Ventures, another Houston firm, also participated with additional strategic partners.

TrueLeap reports that the funding will support the large-scale rollout of its "edge AI, integrated learning systems and last-mile broadband across underserved communities."

“The last mile is where most digital transformation efforts break down,” Sandip Bordoloi, CEO and president of TrueLeap, said in a news release. “TrueLeap was built to operate where bandwidth is limited, power is unreliable, and institutions need real systems—not pilots. This round allows us to scale infrastructure that actually works on the ground.”

True Leap works to address the digital divide in education through its AI-powered education, workforce systems and digital services that are designed for underserved and low-connectivity communities.

The company has created infrastructure in Africa, India and rural America. Just this week, it announced an agreement with the City of Kinshasa in the Democratic Republic of Congo to deploy a digital twin platform for its public education system that will allow provincial leaders to manage enrollment, staffing, infrastructure and performance with live data.

“What sets TrueLeap apart is their infrastructure mindset,” Joe Swinbank, General Partner at Joe Swinbank Family Limited Partnership, added in the news release. “They are building the physical and digital rails that allow entire ecosystems to function. The convergence of edge compute, connectivity, and services makes this a compelling global infrastructure opportunity.”

TrueLeap was founded by Bordoloi and Sunny Zhang and developed out of Born Global Ventures, a Houston venture studio focused on advancing immigrant-founded technology. It closed an oversubscribed pre-seed in 2024.

Texas space co. takes giant step toward lunar excavator deployment

Out of this world

Lunar exploration and development are currently hampered by the fact that the moon is largely devoid of necessary infrastructure, like spaceports. Such amenities need to be constructed remotely by autonomous vehicles, and making effective devices that can survive the harsh lunar surface long enough to complete construction projects is daunting.

Enter San Antonio-based Astroport Space Technologies. Founded in San Antonio in 2020, the company has become a major part of building plans beyond Earth, via its prototype excavator, and in early February, it completed an important field test of its new lunar excavator.

The new excavator is designed to function with California-based Astrolab's Flexible Logistics and Exploration (FLEX) rover, a highly modular vehicle that will perform a variety of functions on the surface of the moon.

In a recent demo, the Astroport prototype excavator successfully integrated with FLEX and proceeded to dig in a simulated lunar surface. The excavator collected an average of 207 lbs (94kg) of regolith (lunar surface dust) in just 3.5 minutes. It will need that speed to move the estimated 3,723 tons (3,378 tonnes) of regolith needed for a lunar spaceport.

After the successful test, both Astroport and Astrolab expressed confidence that the excavator was ready for deployment. "Leading with this successful excavator demo proves that our technology is no longer theoretical—it is operational," said Sam Ximenes, CEO of Astroport.

"This is the first of many implements in development that will turn Astrolab's FLEX rover into the 'Swiss Army Knife' of lunar construction. To meet the infrastructure needs of the emerging lunar economy, we must build the 'Port' before the 'Ship' arrives. By leveraging the FLEX platform, we are providing the Space Force, NASA, and commercial partners with a 'Shovel-Ready' construction capability to secure the lunar high ground."

"We are excited to provide the mobility backbone for Astroport's groundbreaking construction technology," said Jaret Matthews, CEO of Astrolab, in a release. "Astrolab is dedicated to establishing a viable lunar ecosystem. By combining our FLEX rover's versatility with Astroport's civil engineering expertise, we are delivering the essential capabilities required for a sustainable lunar economy."
