Anyone can die of sepsis. The number one killer in hospitals has a reputation for felling the infirm and elderly, but while the immunocompromised are at highest risk, sepsis isn’t that selective.

Take 12-year-old Rory Staunton. In 2012, the healthy boy scratched his arm diving for a ball in gym class at his school in Jackson Heights, NY. Bacteria entered his arm through the cut and he died days later of septic shock.

His story is not unique. Physician Sarma Velamuri saw this firsthand in his internal medicine practice at St. Luke’s Health Center and his residency at Baylor, both in Houston. But it really struck home when he watched helplessly as a friend’s 22-year-old daughter lost her life to sepsis. He had to tell his friend that she would not be coming home.

“There are 300,000-plus people a year who die of sepsis,” says Velamuri. “It’s important that people understand it’s not just those who are most susceptible to infections.”

This fact is not only unfortunate, but preventable. And that’s why Velamuri, who describes himself as “a recovering hospitalist,” co-founded Luminare in 2014. A full-time CEO since 2017, Velamuri, who runs the company with co-founder and CTO Marcus Rydberg, is based in the TMC Innovation Factory.

“Because of the complex workflows in hospitals, sometimes it takes 10 people to get the patient the care they need,” Velamuri explains.

And because of the pervasiveness of sepsis, it’s important to screen every patient who enters an institution before it gets to that point.

Luminare’s technology allows nurses, who are notoriously spread thin, to automatically screen patients in 10 seconds using 50 different parameters.

“We’re looking at a vast amount of data simultaneously,” says Velamuri. “We’re not generating any new data, we’re taking data that exists and shining a light on it.”

In 2020, the technology found a new application when Velamuri and his team created a version of Luminare that helped with the hospital workflow surrounding COVID PCR testing and vaccine management. Since then, it has also been used to help identify and treat monkeypox.

Though Velamuri says he doesn’t want to distract Luminare from its goal of making sepsis the number-two killer in hospitals, he is also aware that his technology can be instrumental in identifying and treating patients at risk for countless other maladies, including heart failure and stroke, and even helping with oncology workflows.

Velamuri says that his team is Luminare’s biggest strength, far more than the AI that they have designed.

“I have this saying that AI is a great servant but a terrible master. It doesn’t solve the problem,” says Velamuri.

Though the company is distributed as far afield as Stockholm, about half of its people live and work in Houston. Of the company’s placement in TMC’s Innovation Factory, Velamuri says, “They’ve been tremendous partners to us. The company would not be as successful today without their supportive partnership.” Not least of that is working with in the same space as other founders who can share their expertise as easily as a trip to the coffee machine.

And the company is growing quickly. Last year, Luminare participated in Cedars-Sinai’s accelerator program. Thanks to that partnership, the hospital is now using Luminare’s technology for sepsis screening. The team is working to partner with even more large hospital systems on solutions for one of the health industry’s biggest problems. And data that shows that Luminare can be the path to preventing death from hospitals’ most prolific killer.

Baylor scientist lands $2M grant to explore links between viruses and Alzheimer’s

Alzheimer’s research

A Baylor College of Medicine scientist will begin exploring the possible link between Alzheimer’s disease and viral infections thanks to a $2 million grant awarded in March.

Dr. Ryan S. Dhindsa is an assistant professor of pathology & immunology at Baylor and a principal investigator at Texas Children’s Duncan Neurological Research Institute (Duncan NRI). He hypothesizes that Alzheimer’s may have some link to previous viral infections contracted by the patient. To study this intriguing possibility, the American Brain Foundation has gifted him the Cure One, Cure Many award in neuroinflammation.

“It is an honor to receive this support from the Cure One, Cure Many Award. Viral infections are emerging as a major, underappreciated driver of Alzheimer's disease, and this award will allow our team to conduct the most comprehensive screen of viral exposures and host genetics in Alzheimer's to date, spanning over a million individuals,” Dhindsa said in a news release. “Our goal is to identify which viruses matter most, why some people are more vulnerable than others, and ultimately move the field closer to new therapeutic strategies for patients.”

Roughly 150 million people worldwide will suffer from Alzheimer’s by 2050, making it the most common cause of dementia in the world. Despite this, scientists are still at a loss as to what exactly causes it.

Dhindsa’s research is part of a new range of theories that certain viral infections may trigger Alzheimer’s. His team will take a two-fold approach. First, they will analyze the medical records of more than a million individuals looking for patterns. Second, they will analyze viral DNA in stem cell-derived brain cells to see how the infections could contribute to neurological decay. The scale of the genomic data gathering is unprecedented and may highlight a link that traditional studies have missed.

Also joining the project are Dr. Caleb Lareau of Memorial Sloan Kettering Cancer Center and Dr. Artem Babaian of the University of Toronto. Should a link be found, it would open the door to using anti-virals to prevent or treat Alzheimer’s.

Tesla Robotaxi service officially launches in Houston and Dallas

Future of the Roads

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.
