A team of Rice University engineers has developed an implantable probe over a hundred times smaller than the width of a hair that aims to help develop better treatments for spinal cord disease and injury.

Detailed in a recent study published in Cell Reports, the probe or sensor, known as spinalNET, is used to explore how neurons in the spinal cord process sensation and control movement, according to a statement from Rice. The research was supported by the National Institutes of Health, Rice, the California-based Salk Institute for Biological Studies, and the philanthropic Mary K. Chapman Foundation based in Oklahoma.

The soft and flexible sensor was used to record neuronal activity in freely moving mice with high resolution for multiple days. Historically, tracking this level of activity has been difficult for researchers because the spinal cord and its neurons move so much during normal activity, according to the team.

“We developed a tiny sensor, spinalNET, that records the electrical activity of spinal neurons as the subject performs normal activity without any restraint,” Yu Wu, a research scientist at Rice and lead author of the study said in a statement. “Being able to extract such knowledge is a first but important step to develop cures for millions of people suffering from spinal cord diseases.”

The team says that before now the spinal cord has been considered a "black box." But the device has already helped the team uncover new findings about the body's rhythmic motor patterns, which drive walking, breathing and chewing.

"Some (spinal neurons) are strongly correlated with leg movement, but surprisingly, a lot of neurons have no obvious correlation with movement,” Wu said in the statement. “This indicates that the spinal circuit controlling rhythmic movement is more complicated than we thought.”

The team said they hope to explore these findings further and aim to use the technology for additional medical purposes.

“In addition to scientific insight, we believe that as the technology evolves, it has great potential as a medical device for people with spinal cord neurological disorders and injury,” Lan Luan, an associate professor of electrical and computer engineering at Rice and a corresponding author on the study, added in the statement.

Rice researchers have developed several implantable, minimally invasive devices to address health and mental health issues.

In the spring, the university announced that the United States Department of Defense had awarded a four-year, $7.8 million grant to the Texas Heart Institute and a Rice team led by co-investigator Yaxin Wang to continue to break ground on a novel left ventricular assist device (LVAD) that could be an alternative to current devices that prevent heart transplantation.

That same month, the university shared news that Professor Jacob Robinson had published findings on minimally invasive bioelectronics for treating psychiatric conditions. The 9-millimeter device can deliver precise and programmable stimulation to the brain to help treat depression, obsessive-compulsive disorder and post-traumatic stress disorder.

Houston startup with unique vascular innovation enrolls subjects in new trial

medical device momentum

A Houston-based company has enrolled the initial subjects in a first-of-its-kind trial.

VenoStent was created to improve vascular surgery outcomes for patients undergoing arteriovenous fistula (AVF) creation surgery.

“When a vein is connected to an artery, as in AVF creation, the vein experiences a 10x increase in pressure and flow that is traumatizing to veins. Many fail to become usable for dialysis,” Geoffrey Lucks, VenoStent COO and co-founder, says in a news release.

Enter VenoStent’s SelfWrap Bioabsorbable Perivascular Wrap, better known as simply SelfWrap. In May 2023, SelfWrap gained FDA approval to begin its US IDE Study, SAVE-FistulaS: The SelfWrap-Assisted ArterioVEnous Fistula Study.

Roughly half a million Americans need hemodialysis just to survive another day. Nearly all of those patients require a vascular access creation surgery, but the procedure has a 50-percent failure rate in its first year. VenoStent and SelfWrap are aimed at improving those odds. It works by using the body’s own healing mechanism.

SelfWrap is a flexible, bioabsorbable vascular wrap that helps to recreate the arterial environment in veins. Over time, the body replaces the SelfWrap with venous tissue.

The company has begun to enroll patients for what will eventually be a 200-subject study. Some of those people have radiocephalic fistulas, others have brachiocephalic ones. This is important, because it will likely prove that the technology works for most types of AVFs. The sites for this clinical trial are at the Surgical Specialists of Charlotte, P.A. in Charlotte, NC, and the Cardiothoracic and Vascular Surgeons in Austin.

“While it’s ambitious and sets a high bar for FDA Approval, we owe it to the chronic kidney disease (CKD) patient community to provide the highest level of clinical evidence,” Timothy Boire, CEO and cofounder, says in the release. “We’re confident based on years of preclinical and clinical data that we’ll demonstrate superiority to standard of care with this breakthrough technology.”

VenoStent recently completed a $16 million Series A, financed by Good Growth Capital and IAG Capital. This is the first-ever randomized controlled trial of a medical device designed to improve outcomes from arteriovenous fistula (AVF) creation surgery in the United States.

Rice University medical device spinout secures nearly $19M series A

fresh funding

A health tech startup based out of a newly formed accelerator program at Rice University has raised venture funding.

Motif Neurotech closed its series A round with an oversubscribed $18.75 million. The company, which develops minimally invasive bioelectronics for mental health treatment, was formed out of the Rice Biotech Launch Pad that launched last fall.

The round was led by Arboretum Ventures, with participation from new investors KdT Ventures, Satori Neuro, Dolby Family Ventures, re.Mind Capital and existing investors Divergent Capital, TMC Venture Fund, PsyMed Ventures, Empath Ventures and Capital Factory, according to a news release from Rice.

“Minimally invasive bioelectronics are the future of mental health treatment,” Jacob Robinson, CEO and founder of Motif Neurotech, says in the release. “Thirty percent of patients with depression don’t respond to two or more medications, and there is a significant need for additional treatment options that are effective and easily accessible."

The fresh funding will go toward developing the inaugural product, the DOT microstimulator, a wireless, battery-free device that can provide at-home therapy for treatment-resistant depression, or TRD, a major depressive disorder.

“This is a pivotal moment for the company as it closes its Series A in addition to the recent successful completion of the proof-of-concept first-in-human implant of the DOT stimulator device," Tom Shehab, managing partner of Arboretum Ventures, says in the release. "We believe Motif’s device will greatly improve the quality of life for patients who have been diagnosed with difficult to treat mental health disorders, including TRD."

Shehab, along with Amy Kruse, chief investment officer of Satori Neuro, will reportedly join Motif Neurotech's board of directors alongside Anthony Arnold, president and CEO of Sensydia Corporation, and Jacob Robinson, professor of electrical and computer engineering and bioengineering at Rice.

The Rice Biotech Launch Pad was established to take biotech innovations from concept to clinical trials in five years or less. It occupies 15,000 square feet of space on campus and is funded through federal grants and donations.

Houston innovator makes major headway on his portable stroke rehab device

research milestone

A University of Houston professor has taking a huge step in advancing his game-changing stroke recovery tech.

Jose Luis Contreras-Vidal, the director of the UH BRAIN Center, recently published his work on a noninvasive brain-machine in a summer issue of the journal Sensors. InnovationMap first reported on Contreras-Vidal's technology in 2022, when it was being tested.

Contreras-Vidal's device uses a wireless, mobile dry-electrode headset placed on the scalp to convert electroencephalography (EEG) recordings (or measurements of electrical activity in different parts of the brain) to interface with a closed-loop brain–computer (BCI) and communicate with exoskeleton devices. Together, the technology triggers robotic movement based on the wearer's brain activity.

The technology has potential to boost cortical plasticity after a stroke, which can improve motor skills recovery.

According to a statement from UH, a patent is pending on Contreras-Vidal's BCI algorithm and the self-positioning dry electrode bracket used on the scalp. The technology has also now been validated and tested at the University of Houston.

Contreras-Vidal says the technology makes stroke recovery easier for the user and even possible at home.

“Most commercial EEG-based BCI systems are tethered to immobile processing hardware or require complex programming or set-up, making them difficult to deploy outside of the clinic or laboratory without technical assistance or extensive training," he says in a statement. "A portable and wireless BCI system is highly preferred so it can be used outside lab in clinical and non-clinical mobile applications at home, work, or play.”

Additionally, the technology uses off-the-shelf components and is adjustable to fit about 90 percent of the population, according to UH.

"Current commercial EEG amplifiers and BCI headsets are prohibitively expensive, lack interoperability, or fail to provide a high signal quality or closed-loop operation, which are vital for BCI applications,” Contreras-Vidal adds.

The development of this technology was originally funded in part by an $813,999 grant from the National Science Foundation’s Division of Translational Impacts. UH reports that about 795,000 people in the United States suffer from a stroke annually.

Other leaders in Houston’s medical industry have tapped into innovative ways to treat and rehabilitate stroke patients in recent years. Baylor St. Luke's Hospital began using AI to reduce the time it takes to treat patients who've suffered from a stroke in 2021.

Houston health tech startup secures $16M series A, prepares for first U.S. clinical trials

money moves

Fueled by fresh funding in the bank, a medical device startup has announced upcoming trials.

VenoStent, Inc., a company developing an innovative tool to improve outcomes for hemodialysis patients, has closed $16 million in a series A round of financing. Two Charleston, South Carolina-based firms — Good Growth Capital and IAG Capital Partners — led the round.

The company also announced it received Investigational Device Exemption from the FDA for its United States clinical trial, SAVE-FistulaS.

“Our mission at VenoStent is to improve the quality and length of life of dialysis patients. On the heels of our very promising results in several preclinical studies and a 20-patient feasibility study that led to our Breakthrough Designation last year, this recent IDE approval is perhaps our biggest milestone to date," Tim Boire, CEO of VenoStent, says in a news release. "We now enter an exciting new epoch in our company’s development that we believe will ultimately result in FDA Approval and vastly improve the quality and length of life for patients."

VenoStent's series A will fund the trial, expand manufacturing capabilities, and more. The company is targeting the more than 800,000 people in the U.S. with end-stage renal disease. Currently, more than half of the surgeries performed to initiate hemodialysis fail within a year. VenoStent's novel therapeutic medical device is a bioabsorbable wrap that reduces vein collapse by providing mechanical support and promoting outward vein growth.

“This trial is designed to provide the highest level of clinical evidence. We’re excited to be in this position to treat the first patients in the United States with this technology, and demonstrate the safety and efficacy of our device,” continues Boire in the release.

Per the release, the company is aiming for FDA Approval and be the first-to-market device to improve hemodialysis access surgery.

“We’re extremely pleased to be partnering with VenoStent on this critical mission. This company and technology are poised for commercial success to address a critical, unmet need,” says Bob Crutchfield, operating partner at Good Growth Capital, in the release.

The TMC Venture Fund also contributed to the series A investment round, along with SNR, Baylor Angel Network / Affinity Fund, Creative Ventures, Cowtown Angels, Alumni Ventures, and other notable angel investors. Past investors in VenoStent include KidneyX, National Science Foundation, National Institute of Health, Y Combinator, Health Wildcatters, and the Texas Halo Fund.

“VenoStent’s data and traction to date is impressive and gives us a lot of confidence in their continued success. We look forward to helping them get this Breakthrough product to market and help patients that are in dire need of this innovative technology,” says Joel Whitley, partner at IAG Capital Partners, in the release.

Houston scientists earn prestigious geophysics career awards

winner, winner

Two Rice University professors have been recognized by the American Geophysical Union, one of the world’s largest associations for Earth and space science.

Rice climatologist Sylvia Dee was awarded the 2025 Nanne Weber Early Career Award by the AGU’s Paleoceanography and Paleoclimatology Section. Richard Gordon, a Rice professor of geophysics also received the 2025 Walter H. Bucher Medal by the AGU. They will both be recognized at the AGU25 event on Dec.15-19 in New Orleans.

The Nanne Weber Early Career Award recognizes contributions to paleoceanography and paleoclimatology research by scientists within 10 years of receiving their doctorate.

“Paleoclimate research provides essential context for understanding Earth’s climate system and its future under continued greenhouse warming," Dee said in a news release. “By studying how climate has evolved naturally in the past, we can better predict the risks and challenges that lie ahead.”

Dee’s work explores how Earth’s natural modes of variability interact with the changing climate and lead to extreme weather. It shows how these interactions can add to climate risks, like flooding and rainfall patterns all around the world.

The Bucher Medal is awarded to just one scientist for their original contributions to the knowledge of the Earth’s crust and lithosphere.

Gordon’s research has reshaped how scientists understand the movement and interaction of Earth’s tectonic plates. He helped reveal the existence of diffuse plate boundaries—areas where the planet’s crust slowly deforms across broad regions instead of along a single fault line. His work also explored true polar wander, a phenomenon in which Earth gradually shifts its orientation relative to its spin axis.

Gordon introduced the concept of paleomagnetic Euler poles, a method for tracing how tectonic plates have moved over millions of years. He also led the development of major global plate motion models, including NUVEL (Northwestern University Velocity) and MORVEL (Mid-Ocean Ridge Velocity).

“Receiving the Walter Bucher Medal is a profound honor,” Gordon said in a news release. “To be included on a list of past recipients whose work I have long admired makes this recognition especially meaningful. There are still countless mysteries about how our planet works, and I look forward to continuing to explore them alongside the next generation of scientists.”

3 Houston-area companies appear on Fortune’s inaugural AI ranking

eyes on ai

Three companies based in the Houston area appear on Fortune’s inaugural list of the top adopters of AI among Fortune 500 companies.

The three companies are:

  • No. 7 energy company ExxonMobil, based in Spring
  • No. 7 tech company Hewlett Packard Enterprise, based in Spring
  • No. 47 energy company Chevron, based in Houston

All three companies have taken a big dive into the AI pool.

In 2024, ExxonMobil’s executive chairman and CEO, Darren Woods, explained that AI would play a key role in achieving a $15 billion reduction in operating costs by 2027.

“There is a concerted effort to make sure that we're really working hard to apply that new technology to the opportunity set within the company to drive effectiveness and efficiency,” Woods told Wall Street analysts.

Hewlett Packard Enterprise is also employing AI to decrease costs. In March, the company announced a restructuring plan — including the elimination of 3,000 jobs — aimed at cutting about $350 million in annual expenses. The restructuring is scheduled to wrap up by the end of October.

Hewlett Packard Enterprise’s Catalyst cost-cutting program includes a push to use AI across the company to improve efficiency, Marie Myers, the company’s executive vice president and chief financial officer, told Wall Street analysts in June.

“Our ambition is clear: A leaner, faster, and more competitive organization. Nothing is off limits. We are focused on rethinking the business — not just reducing our costs, but transforming the way we operate,” Myers said.

At Chevron, AI tools are being used to quickly analyze data and extract insights from it, according to tech news website VentureBeat. Also, Chevron employs advanced AI systems known as large language models (LLMs) to create engineering standards, specifications and safety alerts. AI is even being put to work in Chevron’s exploration initiatives.

Bill Braun, Chevron’s chief information officer, said at a VentureBeat-sponsored event in 2024 that AI-savvy data scientists, or “digital scholars,” are always embedded within workplace teams “to act as a catalyst for working differently.”

The Fortune AIQ 50 ranking is based on ServiceNow’s Enterprise AI Maturity Index, an annual measurement of how prepared organizations are to adopt and scale AI. To evaluate how Fortune 500 companies are rolling out AI and how much they value AI investments, Fortune teamed up with Enterprise Technology Research. The results went into computing an AIQ score for each company.

At the top of the ranking is Alphabet (owner of Google and YouTube), followed by Visa, JPMorgan Chase, Nvidia and Mastercard.

Aside from ExxonMobil, Hewlett Packard Enterprise, and Chevron, two other Texas companies made the list: Arlington-based homebuilder D.R. Horton (No. 29) and Austin-based software company Oracle (No. 37).

“The Fortune AIQ 50 demonstrates how companies across industry sectors are beginning to find real value from the deployment of AI technology,” Jeremy Kahn, Fortune’s AI editor, said in a news release. “Clearly, some sectors, such as tech and finance, are pulling ahead of others, but even in so-called 'old economy' industries like mining and transport, there are a few companies that are pulling away from their peers in the successful use of AI.”
