A team of researchers from Rice University have received a $2 million grant to develop a unique technology that speeds up the analysis of wastewater for viruses from hours to seconds.

The team is based out of Rice’s George R. Brown School of Engineering and led by Rafael Verduzco, associate chair and a professor of chemical and biomolecular engineering and of materials science and nanoengineering. The four-year grant from the National Science Foundation will support the development of the technology, which includes wastewater-testing bioelectric sensors that deliver immediate notice of presence of viruses like SARS-CoV-2, which causes COVID-19, according to a news release from Rice.

The research project — with its partners at the Houston Health Department — have already developed water testing procedures and have analyzed samples from locations around the city. The current process includes taking samples and transferring them to Rice for analysis, but the new technology would be able to monitor systems onsite and instantly. The parties involved with this work are also collaborating with the Centers for Disease Control and Prevention Center of Excellence for wastewater epidemiology that was announced in August.

“Monitoring wastewater for COVID has been pretty effective as a way to get an idea of where we are as a population,” says Verduzco in the release. “But the way it’s done is you have to sample it, you have to do a PCR test and there’s a delay. Our selling point was to get real-time, continuous monitoring to see just how much of this virus is in the wastewater.”

The grant's co-principal investigators include Jonathan Silberg, the Stewart Memorial Professor of BioSciences and director of the Systems, Synthetic and Physical Biology Ph.D. program, and Caroline Ajo-Franklin, a professor of biosciences. Co-investigators also include Lauren Stadler, an assistant professor of civil and environmental engineering, and Kirstin Matthews, a fellow at the Baker Institute for Public Policy.

“These are engineered microbes we’re putting into wastewater, and even though they’re encapsulated, we want to know if there are concerns from health authorities and the general population,” Verduzco said. “Kirstin’s role is to look at the policy side, and also gauge public reaction and educate people about what it means when we talk about engineered bacteria.”

City launches public dashboard for tracking COVID-19 in Houston's wastewater

data points

In 2020, a group of researchers began testing Houston's wastewater to collect data to help identify trends at the community level. Now, the team's work has been rounded up to use as an online resource.

The Houston Health Department and Rice University launched the dashboard on September 22. The information comes from samples collected from the city's 39 wastewater treatment plants and many HISD schools.

"This new dashboard is another tool Houstonians can use to gauge the situation and make informed decisions to protect their families," says Dr. Loren Hopkins, chief environmental science officer for the health department and professor in the practice of statistics at Rice University, in a news release. "A high level of virus in your neighborhood's wastewater means virus is spreading locally and you should be even more stringent about masking up when visiting public places."

The health department, Houston Water, Rice University, and Baylor College of Medicine originally collaborated on the wastewater testing. Baylor microbiologist Dr. Anthony Maresso, director of BCM TAILOR Labs, led a part of the research.

"This is not Houston's first infectious disease crisis," Maresso says in an earlier 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."

It's an affordable way to track the virus, says experts. People with COVID-19 shed viral particles in their feces, according to the release, and by testing the wastewater, the health department can measure important infection rate changes.

The dashboard, which is accessible online now, is color-coded by the level of viral load in wastewater samples, as well as labeled with any recent trend changes. Houstonians can find the interactive COVID-19 wastewater monitoring dashboard, vaccination sites, testing sites, and more information at houstonemergency.org/covid19.

Health tech startup launches Houston study improve stroke patients recovery

now enrolling

A Houston-born company is enrolling patients in a study to test the efficacy of nerve stimulation to improve outcomes for stroke survivors.

Dr. Kirt Gill and Joe Upchurch founded NeuraStasis in 2021 as part of the TMC Biodesign fellowship program.

“The idea for the company manifested during that year because both Joe and I had experiences with stroke survivors in our own lives,” Gill tells InnovationMap. It began for Gill when his former college roommate had a stroke in his twenties.

“It’s a very unpredictable, sudden disease with ramifications not just for my best friend but for everyone in his life. I saw what it did to his family and caregivers and it's one of those things that doesn't have as many solutions for people to continue recovery and to prevent damage and that's an area that I wanted to focus myself on in my career,” Gill explains.

Gill and Upchurch arrived at the trigeminal and vagus nerves as a potential key to helping stroke patients. Gill says that there is a growing amount of academic literature that talks about the efficacy of stimulating those nerves. The co-founders met Dr. Sean Savitz, the director of the UTHealth Institute for Stroke and Cerebrovascular Diseases, during their fellowship. He is now their principal investigator for their clinical feasibility study, located at his facility.

The treatment is targeted for patients who have suffered an ischemic stroke, meaning that it’s caused by a blockage of blood flow to the brain.

“Rehabilitation after a stroke is intended to help the brain develop new networks to compensate for permanently damaged areas,” Gill says. “But the recovery process typically slows to essentially a standstill or plateau by three to six months after that stroke. The result is that the majority of stroke survivors, around 7.6 million in the US alone, live with a form of disability that prevents complete independence afterwards.”

NeuraStasis’ technology is intended to help patients who are past that window. They accomplish that with a non-invasive brain-stimulation device that targets the trigeminal and vagus nerves.

“Think of it kind of like a wearable headset that enables stimulation to be delivered, paired to survivors going through rehabilitation action. So the goal here is to help reinforce and rewire networks as they're performing specific tasks that they're looking to improve upon,” Gill explains.

The study, which hopes to enroll around 25 subjects, is intended to help people with residual arm and hand deficits six months or more after their ischemic stroke. The patients enrolled will receive nerve stimulation three times a week for six weeks. It’s in this window that Gill says he hopes to see meaningful improvement in patients’ upper extremity deficits.

Though NeuraStasis currently boasts just its two co-founders as full-time employees, the company is seeing healthy growth. It was selected for a $1.1 million award from the National Institutes of Health through its Blueprint MedTech program. The award was funded by the National Institute of Neurological Disorders and Stroke. The funding furthers NeuraStasis’ work for two years, and supports product development for work on acute stroke and for another product that will aid in emergency situations.

Gill says that he believes “Houston has been tailor-made for medical healthcare-focused innovation.”

NeuraStasis, he continues, has benefited greatly from its advisors and mentors from throughout the TMC, as well as the engineering talent from Rice, University of Houston and Texas A&M. And the entrepreneur says that he hopes that Houston will benefit as much from NeuraStasis’ technology as the company has from its hometown.

“I know that there are people within the community that could benefit from our device,” he says.

Texas Space Commission launches, Houston execs named to leadership

future of space

Governor Greg Abbott announced the Texas Space Commission, naming its inaugural board of directors and Texas Aerospace Research and Space Economy Consortium Executive Committee.

The announcement came at NASA's Johnson Space Center, and the governor was joined by Speaker Dade Phelan, Representative Greg Bonnen, Representative Dennis Paul, NASA's Johnson Space Center Director Vanessa Wyche, and various aerospace industry leaders.

According to a news release, the Texas Space Commission will aim to strengthen commercial, civil, and military aerospace activity by promoting innovation in space exploration and commercial aerospace opportunities, which will include the integration of space, aeronautics, and aviation industries as part of the Texas economy.

The Commission will be governed by a nine-member board of directors. The board will also administer the legislatively created Space Exploration and Aeronautics Research Fund to provide grants to eligible entities.

“Texas is home to trailblazers and innovators, and we have a rich history of traversing the final frontier: space,” Lieutenant Governor Dan Patrick says in a news release. “Texas is and will continue to be the epicenter for the space industry across the globe, and I have total confidence that my appointees to the Texas Space Commission Board of Directors and the Texas Aerospace Research and Space Economy Consortium Executive Committee will ensure the Texas space industry remains an international powerhouse for cutting-edge space innovation.”

TARSEC will independently identify research opportunities that will assist the state’s position in aeronautics research and development, astronautics, space commercialization, and space flight infrastructure. It also plans to fuel the integration of space, aeronautics, astronautics, and aviation industries into the Texas economy. TARSEC will be governed by an executive committee and will be composed of representatives of each higher education institution in the state.

“Since its very inception, NASA’s Johnson Space Center has been home to manned spaceflight, propelling Texas as the national leader in the U.S. space program,” Abbott says during the announcement. “It was at Rice University where President John F. Kennedy announced that the U.S. would put a man on the moon—not because it was easy, but because it was hard.

"Now, with the Texas Space Commission, our great state will have a group that is responsible for dreaming and achieving the next generation of human exploration in space," he continues. "Texas is the launchpad for Mars, innovating the technology that will colonize humanity’s first new planet. As we look into the future of space, one thing is clear: those who reach for the stars do so from the great state of Texas. I look forward to working with the Texas Space Commission, and I thank the Texas Legislature for partnering with industry and higher education institutions to secure the future of Texas' robust space industry."

The Houston-area board of directors appointees included:

  • Gwen Griffin, chief executive officer of the Griffin Communications Group
  • John Shannon, vice president of Exploration Systems at the Boeing Company
  • Sarah "Sassie" Duggleby, co-founder and CEO of Venus Aerospace
  • Kirk Shireman, vice president of Lunar Exploration Campaigns at Lockheed Martin
  • Dr. Nancy Currie-Gregg, director of the Texas A&M Space Institute

Additionally, a few Houstonians were named to the TARSEC committee, including:

  • Stephanie Murphy, CEO and executive chairman of Aegis Aerospace
  • Matt Ondler, president and former chief technology officer at Axiom Space
  • Jack “2fish” Fischer, vice president of production and operations at Intuitive Machines
  • Brian Freedman, president of the Bay Area Houston Economic Partnership and vice chairman of Wellby Financial
