Houston — home to one of the largest medical centers in the world — isn't a stranger when it comes to medical innovations and breakthrough research discoveries.

In the latest roundup of research innovations, four Houston institutions are working on innovative and — in some cases — life-saving research projects.

Researchers at Houston Methodist have discovered some troubling information about the strains of group A streptococcus that cause strep throat and a flesh-eating disease are becoming more resistant to beta-lactams antibiotics like penicillin.

James M. Musser is the lead author of the study and chair of Methodist's Department of Pathology and Genomic Medicine. The study — which received funding from grants from the Fondren Foundation, Houston Methodist Hospital and Houston Methodist Research Institute, and the National Institutes of Health — appeared in the Jan. 29 issue of the Journal of Clinical Microbiology, according to a news release.

"If this germ becomes truly resistant to these antibiotics, it would have a very serious impact on millions of children around the world," Musser says in the release. "That is a very concerning but plausible notion based on our findings. Development of resistance to beta-lactam antibiotics would have a major public health impact globally."

Musser and his team found 7,025 group A streptococcus strains that have been recorded around the world over the past several decades. Of those strains, 2 percent had gene mutations that raised the alarm for the researchers and, upon investigation, Musser's team came to the conclusion that antibiotic treatments can eventually be less effective — or even completely ineffective. This, Musser says, calls for an urgent need to develop a vaccine.

"We could be looking at a worldwide public health infectious disease problem," says Musser in the release. "When strep throat doesn't respond to frontline antibiotics such as penicillin, physicians must start prescribing second-line therapies, which may not be as effective against this organism."

Mehmet Orman, assistant professor of chemical and biomolecular engineering at the University of Houston, is looking into a specific type of persister cells that have been found to be stubborn and drug-resistant.

The research, which is backed by a $1.9 million grant from the National Institute of Allergy and Infectious Diseases, could answer questions about chronic health issues like airway infections in cystic fibrosis patients, urinary tract infections, and tuberculosis, according to a news release.

"If we know how persister cells are formed, we can target their formation mechanisms to eliminate these dangerous cell types," says Orman in a news release.

Orman is looking into cells' self-digestion, or autophagy, process that is found to stimulate persister formation. Per the release, cells can survive periods of starvation by eating their own elements. Specifically, Orman will analyze self-digestion in E. coli.

"By integrating our expertise in bacterial cell biology with advanced current technologies, we aim to decipher the key components of this pathway to provide a clear and much-needed picture of bacterial self-digestion mechanisms," says Orman in the release.

Scientists at Baylor College of Medicine are looking into the lead cause of kidney failure in patients who undergo surgery. Individuals who have heightened levels of suPAR protein — soluble urokinase-type plasminogen activator receptor — have a greater risk of this post-op complication, according to a news release.

"suPAR is a circulating protein that is released by inflammatory cells in the bone marrow and produced by a number of cell/organs in the body," says Dr. David Sheikh-Hamad, professor of medicine – nephrology at Baylor College of Medicine and collaborating author of the study, in the release.

The study, which was published in The New England Journal of Medicine, conducted research on mice that were engineered to hive high suPAR levels in their blood. Compared to the control mice, the suPAR mice had more risk of kidney industry. These mice were given suPAR-blocking antibodies, which then helped reduce kidney injury.

"This protective strategy may be used in humans expressing high suPAR levels prior to contrast exposure, or surgery to decrease the likelihood of developing kidney failure," Sheikh-Hamad says in the release.

Rice University research finds expressing emotions during mourning is healthier

A new study done by researchers at Rice University finds that spouses that lose their husband or wife and try to suppress their grief are not doing themselves any favors. The study monitored 99 people who had recently lost a spouse, according to a news release.

"There has been work focused on the link between emotion regulation and health after romantic breakups, which shows that distracting oneself from thoughts of the loss may be helpful," says Christopher Fagundes, an associate professor of psychology and the principal investigator, in a news release. "However, the death of a spouse is a very different experience because neither person initiated the separation or can attempt to repair the relationship."

The study included asking participants to respond to how they felt about certain coping strategies, as well as blood tests to measure cytokines levels‚ an inflammatory marker.

"Bodily inflammation is linked to a host of negative health conditions, including serious cardiovascular issues like stroke and heart attack," Fagundes says in the release.

The research, which was funded by a grant from the National Heart, Lung, and Blood Institute, found that the participants who avoided their emotions suffered more of this bodily inflammation.

"The research also suggests that not all coping strategies are created equal, and that some strategies can backfire and have harmful effects, especially in populations experiencing particularly intense emotions in the face of significant life stressors, such as losing a loved one," adss Richard Lopez, an assistant professor of psychology at Bard College and lead author of the study, in the release.

Texas nonprofit grants $68.5M to Houston organizations for recruitment, research

Three prominent institutions in Houston will be able to snag a trio of high-profile cancer researchers thanks to $12 million in new funding from the Cancer Prevention and Research Institute of Texas.

The biggest recruitment award — $6 million — went to the University of Texas MD Anderson Center to lure researcher Xiling Shen away from the Terasaki Institute for Biomedical Innovation in Los Angeles.

Shen is chief scientific officer at the nonprofit Terasaki Institute. His lab there studies precision medicine, including treatments for cancer, from a “systems biology perspective.”

He also is co-founder and former CEO of Xilis, a Durham, North Carolina-based oncology therapy startup that raised $70 million in series A funding in 2021. Before joining the institute in 2021, the Stanford University graduate was an associate professor at Duke University in Durham.

Shen and Xilis aren’t strangers to MD Anderson.

In 2023, MD Anderson said it planned to use Xilis’ propriety MicroOrganoSphere (MOS) technology for development of novel cancer therapies.

“Our research suggests the MOS platform has the potential to offer new capabilities and to improve the efficiency of developing innovative drugs and cell therapies over current … models, which we hope will bring medicines to patients more quickly,” Shen said in an MD Anderson news release.

Here are the two other Cancer Prevention and Research Institute of Texas (CPRIT) awards that will bring noted cancer researchers to Houston:

  • $4 million to attract David Sarlah to Rice University from the University of Illinois, where he is an associate professor of chemistry. Sarlah’s work includes applying the principles of chemistry to creation of new cancer therapies.
  • $2 million to lure Vishnu Dileep to the Baylor College of Medicine from the Massachusetts Institute of Technology (MIT), where he is a postdoctoral fellow. His work includes the study of cancer genomes.

CPRIT also handed out more than $56.5 million in grants and awards to seven institutions in the Houston area. Here’s the rundown:

  • MD Anderson Cancer Center — Nearly $25.6 million
  • Baylor College of Medicine — Nearly $11.5 million
  • University of Texas Health Science Center at Houston — More than $6 million
  • Rice University — $4 million
  • University of Texas Medical Branch at Galveston — More than $3.5 million
  • Methodist Hospital Research Institute — More than $3.3 million
  • University of Houston — $1.4 million

Dr. Pavan Reddy, a CPRIT scholar who is a professor at the Baylor College of Medicine and director of its Dan L Duncan Comprehensive Cancer Care Center, says the CPRIT funding “will help our investigators take chances and explore bold ideas to make innovative discoveries.”

The Houston-area funding was part of nearly $99 million in grants and awards that CPRIT recently approved.

Houston space company's lunar lander touches down on the moon in historic mission

touchdown

A private lander on Thursday made the first U.S. touchdown on the moon in more than 50 years, but managed just a weak signal back until flight controllers scrambled to gain better contact.

Despite the spotty communication, Intuitive Machines, the company that built and managed the craft, confirmed that it had landed upright. But it did not provide additional details, including whether the lander had reached its intended destination near the moon’s south pole. The company ended its live webcast soon after identifying a lone, weak signal from the lander.

“What we can confirm, without a doubt, is our equipment is on the surface of the moon,” mission director Tim Crain reported as tension built in the company’s Houston control center.

Added Intuitive Machines CEO Steve Altemus: “I know this was a nail-biter, but we are on the surface and we are transmitting. Welcome to the moon.”

Data was finally starting to stream in, according to a company announcement two hours after touchdown.

The landing put the U.S. back on the surface for the first time since NASA’s famed Apollo moonwalkers.

Intuitive Machines also became the first private business to pull off a lunar landing, a feat achieved by only five countries. Another U.S. company, Astrobotic Technology, gave it a shot last month, but never made it to the moon, and the lander crashed back to Earth. Both companies are part of a NASA-supported program to kick-start the lunar economy.

Astrobotic was among the first to relay congratulations. “An incredible achievement. We can’t wait to join you on the lunar surface in the near future,” the company said via X, formerly Twitter.

Intuitive Machines “aced the landing of a lifetime,” NASA Administrator Bill Nelson tweeted.

The final few hours before touchdown were loaded with extra stress when the lander's laser navigation system failed. The company's flight control team had to press an experimental NASA laser system into action, with the lander taking an extra lap around the moon to allow time for the last-minute switch.

With this change finally in place, Odysseus descended from a moon-skimming orbit and guided itself toward the surface, aiming for a relatively flat spot among all the cliffs and craters near the south pole.

As the designated touchdown time came and went, controllers at the company's command center anxiously awaited a signal from the spacecraft some 250,000 miles (400,000 kilometers) away. After close to 15 minutes, the company announced it had received a weak signal from the lander.

Launched last week, the six-footed carbon fiber and titanium lander — towering 14 feet (4.3 meters) — carried six experiments for NASA. The space agency gave the company $118 million to build and fly the lander, part of its effort to commercialize lunar deliveries ahead of the planned return of astronauts in a few years.

Intuitive Machines' entry is the latest in a series of landing attempts by countries and private outfits looking to explore the moon and, if possible, capitalize on it. Japan scored a lunar landing last month, joining earlier triumphs by Russia, U.S., China and India.

The U.S. bowed out of the lunar landscape in 1972 after NASA's Apollo program put 12 astronauts on the surface. Astrobotic of Pittsburgh gave it a shot last month, but was derailed by a fuel leak that resulted in the lander plunging back through Earth's atmosphere and burning up.

Intuitive Machines’ target was 186 miles (300 kilometers) shy of the south pole, around 80 degrees latitude and closer to the pole than any other spacecraft has come. The site is relatively flat, but surrounded by boulders, hills, cliffs and craters that could hold frozen water, a big part of the allure. The lander was programmed to pick, in real time, the safest spot near the so-called Malapert A crater.

The solar-powered lander was intended to operate for a week, until the long lunar night.

Besides NASA’s tech and navigation experiments, Intuitive Machines sold space on the lander to Columbia Sportswear to fly its newest insulating jacket fabric; sculptor Jeff Koons for 125 mini moon figurines; and Embry-Riddle Aeronautical University for a set of cameras to capture pictures of the descending lander.
