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.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
