According to researchers at Baylor College of Medicine, who are working in partnership with the Houston Health Department and Rice University, testing the city's wastewater for SARS-CoV2 can help predict where outbreaks are likely to happen.

In May, researchers analyzed wastewater samples that were collected every week from 39 sites in the city and found traces of the virus. The research project was directed by Baylor microbiologist Dr. Anthony Maresso, director of BCM TAILOR Labs.

"This is not Houston's first infectious disease crisis," Maresso says in a news release. "Wastewater sampling was pioneered by Joseph Melnick, the first chair of Baylor's Department of Molecular Virology and Microbiology, to get ahead of polio outbreaks in Houston in the 1960s. This work essentially ushered in the field of environmental virology, and it began here at Baylor. TAILOR Labs is just continuing that tradition by providing advanced science measures to support local public health intervention."

The researchers will continue into 2021 and are working with the city and local governments on their findings.

"It's a cost effective way to gauge Houston's total viral load. It tracks well ahead of positivity rate, 10 days in some cases," sways Dr. Austen Terwilliger, director of operations at TAILOR, in the release. "At the moment, we are at the lowest viral levels since we started sampling, which is excellent news."

University of Houston researchers looking into effect of pandemic on mental illness

While physical health and economic impacts of the coronavirus have been the focus of attention amid the pandemic, mental health effects are estimated to inflict more damage if not address, according to new research by Michael Zvolensky, University of Houston professor of psychology and director of the Anxiety and Health Research Laboratory/Substance Use Treatment Clinic.

Zvolensky has published two papers on his research discussing the psychological behavior issues related to the COVID-19 pandemic from a behavioral science perspective, according to a press release from UH.

"The impact of COVID-19 on psychological symptoms and disorders, addiction and health behavior is substantial and ongoing and will negatively impact people's mental health and put them at greater risk for chronic illness and drug addiction," reports Zvolensky in Behaviour Research and Therapy. "It will not equally impact all of society. Those at greater risk are those that have mental health vulnerabilities or disorders."

For those who 'catastrophize' the pandemic, Zvolensky explains in his paper, the impact from stress is increased — as is the possibility for substance abuse.

"That sets in motion a future wave of mental health, addiction and worsening health problems in our society. It's not going to go away, even with a vaccination, because the damage is already done. That's why we're going to see people with greater health problems struggling for generations," says Zvolensky in the release.

He evaluated a group of 160 participants on pandemic-related fear and worry and substance abuse as a coping method. The "results may provide critical clinical information for helping individuals cope with this pandemic," he says.

Bioinformatics research group at Rice University is designing novel SARS-CoV-2 test

Can software help save lives in this pandemic? A Rice University computer scientist thinks it's worth a shot.

Bioinformatics researcher Todd Treangen is working with a molecular diagnostics company to optimize the design and computational evaluation of molecular detection assays for viral RNA of SARS-CoV-2, according to a press release from Rice. Great Basin Scientific and the Rice researchers hope their work will streamline the development and commercialization of COVID-19 testing.

"This exciting collaboration with Great Basin will allow for computational methods and software developed in my research group to directly contribute to fast, sensitive and affordable detection and monitoring of SARS-CoV-2 and emerging pathogens," Treangen said.

The company, which is based in Salt Lake City, will use Treangen lab's novel bioinformatics software called OliVar to work on the diagnostic test. Great Basin Scientific is expected to seek emergency use authorization for the test from the Food and Drug Administration later this year.

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.”
