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.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
