Researchers and scientists at Rice University and Houston Methodist are developing a “sleep cap” that aims to protect the brain against dementia and other similar diseases by measuring and improving deep sleep.

The project is a collaboration between Rice University engineering professors Daniel Preston, Vanessa Sanchez and Behnaam Aazhang; and Houston Methodist neurologist Dr. Timea Hodics and Dr. Gavin Britz, director of the Houston Methodist Neurological Institute and chairman of the Department of Neurosurgery.

According to Rice, deep sleep is essential for clearing waste products from the brain and nightly “cleaning cycles” help remove toxic proteins. These toxic proteins, like amyloids, can accumulate during the day and are linked to Alzheimer’s disease and other neurological issues.

Aazhang, director of the Rice Neuroengineering Initiative, and his team are building a system that not only tracks the brain’s clearing process but can also stimulate it, improving natural mechanisms that protect against neurodegeneration.

Earlier proof-of-concept versions of the caps successfully demonstrated the promise of this approach; however, they were rigid and uncomfortable for sleep.

Preston and Sanchez will work to transform the design of the cap into a soft, lightweight, textile-based version to make sleep easier, while also allowing the caps to be customizable and tailored for each patient.

“One of the areas of expertise we have here at Rice is designing wearable devices from soft and flexible materials,” Preston, an assistant professor of mechanical engineering, said in a news release. “We’ve already shown this concept works in rigid device prototypes. Now we’re building a soft, breathable cap that people can comfortably wear while they sleep.”

Additionally, the research team is pursuing ways to adapt their technology to measure neuroinflammation and stimulate the brain’s natural plasticity. Neuroinflammation, or swelling in the brain, can be caused by injury, stroke, disease or lifestyle factors and is increasingly recognized as a driver of neurodegeneration, according to Rice.

“Our brain has an incredible ability to rewire itself,” Aazhang added in the release. “If we can harness that through technology, we can open new doors for treating not just dementia but also traumatic brain injury, stroke, Parkinson’s disease and more.”

The project represents Rice’s broader commitment to brain health research and its support for the Dementia Prevention Research Institute of Texas (DPRIT), which passed voter approval last week. The university also recently launched its Rice Brain Institute.

As part of the project, Houston Methodist will provide access to clinicians and patients for early trials, which include studies on patients who have suffered traumatic brain injury and stroke.

“We have entered an era in neuroscience that will result in transformational cures in diseases of the brain and spinal cord,” Britz said in the release. “DPRIT could make Texas the hub of these discoveries.”

Bairitone Health

Bairitone Health is bringing anatomy imaging for sleep apnea to the home environment. The company's platform maps users' anatomy during natural sleep using a facial patch to determine the root cause of airway obstruction. It then offers effective therapies for each patient. The system is currently in the research and development phase and is being used in clinical trials and studies.

The company was founded in 2022 in the Texas Medical Center's Biodesign program by CEO Meagan Pitcher, CTO Onur Kilic and chief medical officer Britt Cross. It was a member of Activate Houston's inaugural cohort and has participated in numerous accelerators and incubators. It raised a pre-seed round last year of $435,000.

Corveus Medical

Corveus Medical has developed a novel catheter device that allows cardiologists to perform a splanchnic nerve ablation, restoring the pressure balance in patients with moderate heart failure. Its pre-FDA-approved, minimally invasive solution deactivates a nerve that has been demonstrated to be a root cause behind heart failure progression, which allows physicians to treat patients who have traditionally had few options.

The company, formerly known as Caridian Medical, was founded in 2021 by CEO Tyler Melton and CMO Ishan Kamat. It has participated in incubators such as TMC Biodesign, Y Combinator, MedTech Innovator and Fogarty Innovation and was named one of the 10 most promising life science companies at Texas Life Science Forum in 2022. The company says it will move toward validation and verification testing for its device in Q4 of this year.

FibroBiologics

Regenerative medicine company FibroBioligics uses fibroblasts, the body’s most common type of cell, rather than stem cells, to help grow new cells to repair tissue and modulate the immune system. The cell therapies offer treatments for chronic conditions such as degenerative disc disease, multiple sclerosis and non-healing wounds.

The publicly traded company was founded in 2021 by CEO Pete O'Heeron. It opened a new 10,000-square-foot Houston lab earlier this year to scale up research efforts and pave the way for in-house manufacturing. The company says it plans to launch its first clinical trial for diabetic foot ulcers soon, representing the transition of its fibroblast technology to the clinic setting.

Koda Health

Koda Health has developed an advance care planning platform (ACP) that allows users to document and share their care preferences, goals and advance directives for health systems. The web-based platform guides patients through values-based decisions with interactive tools and generates state-specific, legally compliant documents that integrate seamlessly with electronic health record systems. The company also added kidney action planning to its suite of services for patients with serious illnesses last year.

Koda Health was founded out of the TMC's Biodesign Fellowship in 2020 by CEO Tatiana Fofanova, chief medical officer Dr. Desh Mohan, and chief technology officer Katelin Cherry. The company raised a $7 million series A earlier this year, and also announced major partnerships and integrations with Epic, Guidehealth, Medical Home Network, Privia Health and others.

NanoEar

NanoEar has miniaturized hearing aid technology so that it can be implanted across the eardrum, allowing adults with age-related hearing loss to enjoy better sound quality than they would with behind-the-ear hearing aids.

Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist, developed the technology, and the company was founded in 2016 with CFO Willem Vermaat and COO Michael Moore. The company participated in the TMC Innovation Institute in 2016. It has issued nine U.S. patents and performed successful human cadaver and animal proof-of-concept experiments. Its next step is developing a prototype.

Wellysis USA

Wellysis USA Inc. works to detect heart rhythm disorders with its continuous ECG/EKG monitor with AI reporting. Its S-Patch cardiac monitor is designed for extended testing periods of up to 14 days on a single battery charge. The device weighs only 9 grams, is waterproof and designed to be comfortable to wear, and is considered to have a high detection rate for arrhythmias. It is ideally suited for patient-centric clinical trials to help physicians make diagnoses faster, cheaper and more conveniently.

It was established in Houston in 2023 and participated in the JLABS SFF Program the same year. It closed a $12 million series B last year. It was founded by CEO Young Juhn, CTO Rick Kim, CFO JungSoo Kim and chief strategy officer JoongWoo Kim.

10 Houston companies clock in with best corporate cultures, says Forbes

Where to Work

Two of Houston's biggest medical institutions – Houston Methodist and MD Anderson Cancer Center – have just landed top-50 spots on Forbes' new ranking of "America's Best Employers for Company Culture." The report highlighted eight more Houston-area companies for their inspiring company culture.

Forbes partnered with market research firm Statista to survey over 218,000 workers at companies with at least 1,000 employees throughout the U.S, and relied on data from the past three years of employee surveys (with an emphasis on the most recent data and recommendations from current employees). Companies don't pay to be included, Forbes additionally noted.

Among the final list of 600 U.S. companies, 30 Texas employers were praised for providing "a unifying company culture that inspires a sense of purpose and loyalty among employees."

Houston Methodist climbed into the No. 15 spot nationally and outranked all other Texas companies on the list, while MD Anderson ranked 47th nationwide. Both institutions have dominated U.S. News' annual rankings of the best Texas hospitals for over a decade, proving exactly how having a great company culture can also improve the service provided to patients.

According to the report's research, employers with a successful company culture don't rely on "surface-level perks" such as free lunches, wellness apps, and flex days to inspire employee engagement. Instead, employers that focused on conflict resolution and coaching their managers saw a reduction in employee burnout and an increase in "perceptions of fairness and leadership care."

"In fact, the researchers noted that when 'senior leaders changed how they led — how they ran meetings, gave feedback, made decisions and responded to challenge — trust scores rose by an average of 26 percent,'" the report said.

The eight other Houston-area companies that earned national acclaim for their company culture are:

  • No. 220 – Stewart Info Services
  • No. 325 – BP
  • No. 332 – Baylor College of Medicine
  • No. 492 – Chevron Phillips Chemical, The Woodlands
  • No. 525 – Insperity
  • No. 558 – NRG Energy
  • No. 586 – Waste Management
  • No. 593 – LyondellBassell

Other Texas employers with great company culture:

Elsewhere in Texas, 15 North Texas companies and five Central Texas companies were included on Forbes' list of employers with the best company culture.

The three Austin-area companies that earned spots on the list include Austin Community College District (No. 56), Round Rock-based Dell Technologies (No. 207), and Keller Williams Realty (No. 352).

The two San Antonio-based companies that made the cut are beloved Texas grocery chain H-E-B (No. 445), and municipal electric utility company CPS Energy (No. 551).

The 15 Dallas-Fort Worth-based companies that made the list include:

  • No. 58 – The Container Store, Coppell
  • No. 73 – Lewisville Independent School District, Lewisville
  • No. 117 – Southwest Airlines, Dallas
  • No. 123 –Topgolf, Dallas
  • No. 170 – McKesson, Irving
  • No. 190 – Kimberly-Clark, Irving
  • No. 245 – Jacobs Solutions,Dallas
  • No. 312 – Brinker International, Coppell
  • No. 350 – Texas Health Resources, Arlington
  • No. 482 – Toyota North America, Plano

Houston Methodist receives $25M gift, renames department of medicine

med funding

Houston-based nonprofit The Duncan Fund has awarded a $25 million gift to Houston Methodist's department of medicine to establish new endowed fellowships, streamline complex care and bring artificial intelligence into the fold to develop more personalized treatment plans.

In turn, the health care system announced that it will rename the department the Houston Methodist Charles W. Duncan Jr. Department of Medicine.

“We are deeply appreciative of the Duncan family’s support, which allows us to further programs at the intersection of personalized medicine and preventive health care to benefit our patients,” Dr. Eleftherios Mylonakis, chair of the department and the Charles and Anne Duncan Presidential Distinguished Chair, said in a news release.

The department of medicine is Houston Methodist's largest, and comprises 14 clinical programs, ranging from general medicine to highly specialized care, as well as research and education.

According to Houston Methodist, the latest grant from the Duncan family will:
  • Coordinate complex, multidisciplinary care by hospitalists
  • Implement programs that leverage data and AI to tailor treatments and preventive strategies
  • Establish five endowed fellowships, including a new fellowship for students known as MedTech Innovator

“Our vision is to redefine how care is delivered in our country by creating a national model for true continuity — one that follows the patient across every transition, from home to hospital and back again,” Mylonakis added in the release. “We are also advancing a deeper understanding of health span, shifting from reactive treatment to a proactive, lifelong strategy that maximizes not just how long we live but how well we live.”

The Duncan family has been a longtime supporter of Houston Methodist—and Houston organizations at large. The late Charles Duncan Jr. sat on the system's board for decades, and his son, Charles “Carlos” Duncan III, serves on the Houston Methodist Hospital Foundation Board. Additionally, the family established the Charles and Anne Duncan Scholars Program and endowed chairs in nephrology and endocrinology.

Charles Duncan Jr. is also the namesake behind Rice University's Duncan Residential College and was one of the founders of the Greater Houston Partnership. He served as Secretary of Energy during the Carter Administration.

Rice University researchers unveil new model that could sharpen MRI scans

MRI innovation

Researchers at Rice University, in collaboration with Oak Ridge National Laboratory, have developed a new model that could lead to sharper imaging and safer diagnostics using magnetic resonance imaging, or MRI.

In a study recently published in The Journal of Chemical Physics, the team of researchers showed how they used the Fokker-Planck equation to better understand how water molecules respond to contrast agents in a process known as “relaxation.” Previous models only approximated how water molecules relaxed around contrasting agents. However, through this new model, known as the NMR eigenmodes framework, the research team has uncovered the “full physical equations” to explain the process.

“The concept is similar to how a musical chord consists of many notes,” Thiago Pinheiro, the study’s first author, a Rice doctoral graduate in chemical and biomolecular engineering and postdoctoral researcher in the chemical sciences division at Oak Ridge National Laboratory, said in a news release. “Previous models only captured one or two notes, while ours picks up the full harmony.”

According to Rice, the findings could lead to the development and application of new contrast agents for clearer MRIs in medicine and materials science. Beyond MRIs, the NMR relaxation method could also be applied to other areas like battery design and subsurface fluid flow.

“In the present paper, we developed a comprehensive theory to interpret those previous molecular dynamics simulations and experimental findings,” Dilipkumar Asthagiri, a senior computational biomedical scientist in the National Center for Computational Sciences at Oak Ridge National Laboratory, said in the release. ”The theory, however, is general and can be used to understand NMR relaxation in liquids broadly.”

The team has also made its code available as open source to encourage its adoption and further development by the broader scientific community.

“By better modeling the physics of nuclear magnetic resonance relaxation in liquids, we gain a tool that doesn’t just predict but also explains the phenomenon,” Walter Chapman, a professor of chemical and biomolecular engineering at Rice, added in the release. “That is crucial when lives and technologies depend on accurate scientific understanding.”

The study was backed by The Ken Kennedy Institute, Rice Creative Ventures Fund, Robert A. Welch Foundation and Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory.

Luxury transportation startup connects Houston with Austin and San Antonio

On The Road Again

Houston business and leisure travelers have a luxe new way to hop between Texas cities. Transportation startup Shutto has launched luxury van service connecting San Antonio, Austin, and Houston, offering travelers a comfortable alternative to flying or long-haul rideshare.

Bookings are now available Monday through Saturday with departure times in the morning and evening. One-way fares range from $47-$87, putting Shutto in a similar lane to Dallas-based Vonlane, which also offers routes from Houston to Austin and San Antonio.

Shutto enters the market at a time when highway congestion is a hotter topic than ever. With high-speed rail still years in the future, its model aims to provide fast, predictable service at commuter prices.

The startup touts an on-time departure guarantee and a relaxed, intimate ride. Only 12 passengers fit inside each Mercedes Sprinter van, equipped with Wi-Fi and leather seating. And each route includes a pit stop at roadside favorite Buc-ee's.

In announcing the launch, founder and CEO Alberto Salcedo called the company a new category in Texas mobility.

“We are bringing true disruptive mobility to Texas: faster and more convenient than flying (no security lines, no delays), more comfortable and exclusive than the bus or train, and up to 70 percent cheaper than private transfers or Uber Black,” Salcedo said in a release.

“Whether you’re commuting for business, visiting family, exploring Texas wineries, or doing a taco tour in San Antonio, Shutto makes traveling between these cities as easy and affordable as riding inside the city."

Beyond the scheduled routes, Shutto offers private, customizable trips anywhere in the country, a service it expects will appeal to corporate retreat planners, party planners, and tourists alike.

In Houston, the service picks up and drops off near the Galleria at the Foam Coffee & Kitchen parking lot, 5819 Richmond Ave.. In San Antonio, it is located at La Panadería Bakery’s parking lot at 8305 Broadway. In Austin, the location is the Pershing East Café parking lot at 2501 E. Fifth St.

Houston-area lab grows with focus on mobile diagnostics and predictive medicine

mobile medicine

When it comes to healthcare, access can be a matter of life and death. And for patients in skilled nursing facilities, assisted living or even their own homes, the ability to get timely diagnostic testing is not just a convenience, it’s a necessity.

That’s the problem Principle Health Systems (PHS) set out to solve.

Founded in 2016 in Clear Lake, Texas, PHS began as a conventional laboratory but quickly pivoted to mobile diagnostics, offering everything from core blood work and genetic testing to advanced imaging like ultrasounds, echocardiograms, and X-rays.

“We were approached by a group in a local skilled nursing facility to provide services, and we determined pretty quickly there was a massive need in this area,” says James Dieter, founder, chairman and CEO of PHS. “Turnaround time is imperative. These facilities have an incredibly sick population, and of course, they lack mobility to get the care that they need.”

What makes PHS unique is not only what they do, but where they do it. While they operate one of the largest labs serving skilled nursing facilities in the state, their mobile teams go wherever patients are, whether that’s a nursing home, a private residence or even a correctional facility.

Diagnostics, Dieter says, are at the heart of medical decision-making.

“Seventy to 80 percent of all medical decisions are made from diagnostic results in lab and imaging,” he says. “The diagnostic drives the doctor’s or the provider’s next move. When we recognized a massive slowdown in lab results, we had to innovate to do it faster.”

Innovation at PHS isn’t just about speed; it’s about accessibility and precision.

Chris Light, COO, explains: “For stat testing, we use bedside point-of-care instruments. Our phlebotomists take those into the facilities, test at the bedside, and get results within minutes, rather than waiting days for results to come back from a core lab.”

Scaling a mobile operation across multiple states isn’t simple, but PHS has expanded into nine states, including Texas, Oklahoma, Kansas, Missouri and Arizona. Their model relies on licensed mobile phlebotomists, X-ray technologists and sonographers, all trained to provide high-level care outside traditional hospital settings.

The financial impact for patients is significant. Instead of ambulance rides and ER visits costing thousands, PHS services often cost just a fraction, sometimes only tens or hundreds of dollars.

“Traditionally, without mobile diagnostics, the patient would be loaded into a transportation vehicle, typically an ambulance, and taken to a hospital,” Dieter says. “Our approach is a fraction of the cost but brings care directly to the patients.”

The company has also embraced predictive and personalized medicine, offering genetic tests that guide medication decisions and laboratory tests that predict cognitive decline from conditions like Alzheimer's and Parkinson’s.

“We actively look for complementary services to improve patient outcomes,” Dieter says. “Precision medicine and predictive testing have been a great value-add for our providers.”

Looking to the future, PHS sees mobile healthcare as part of a larger trend toward home-based care.

“There’s an aging population that still lives at home with caretakers,” Dieter explains. “We go into the home every day, whether it’s an apartment, a standalone home, or assisted living. The goal is to meet patients where they are and reduce the need for hospitalization.”

Light highlighted another layer of innovation: predictive guidance.

“We host a lot of data, and labs and imaging drive most treatment decisions,” Light says. “We’re exploring how to deploy diagnostics immediately based on results, eliminating hours of delay and keeping patients healthier longer.”

Ultimately, innovation at PHS isn’t just about technology; it’s about equity.

“There’s an 11-year life expectancy gap between major metro areas and rural Texas,” Dieter says. “Our innovation has been leveling the field, so everyone has access to high-quality diagnostics and care, regardless of where they live.”
