Researchers at Texas A&M University System are collaborating on a new device that uses artificial intelligence in a breathalyzer situation to detect whether individuals should be tested for COVID-19. The technology is being developed through a collaboration with Dallas-based company, Worlds Inc., and the U.S. Air Force.

The device is called Worlds Protect and a patient can use a disposable straw to blow into a copper inlet. In less than a minute, test results can be sent to the person's smartphone. Worlds Inc. co-founders Dave Copps and Chris Rohde envision Worlds Protect kiosks outside of highly populated areas to act as a screening process, according to a news release.

"People can walk up and, literally, just breathe into the device," says Rohde, president of Worlds Inc., in the release. "It's completely noninvasive. There's no amount of touching. And you quickly get a result. You get a yay or nay."

The university system has contributed $1 million in the project's development and is assisting Worlds Inc. with engineering and design, prototype building and the mapping of a commercial manufacturing process. According to the release, the plan was to test the prototypes will be tried out this fall on the Texas A&M campus.

"Getting tech innovations to market is one of our sweet spots," says John Sharp, chancellor of the Texas A&M System, in the release. "This breakthrough could have lasting impact on global public health."

Baylor College of Medicine researchers to determine cyclosporine’s role in treating hospitalized COVID-19 patients

The Baylor College of Medicine has launched a randomized clinical trial to look into how the drug cyclosporine effects the prevention of disease progression in pre-ICU hospitalized COVID-19 patients. The drug has been used for about 40 years to prevent rejection of organ transplants and to treat patients with rheumatoid arthritis and psoriasis.

"The rationale is strong because the drug has a good safety profile, is expected to target the body's hyperimmune response to COVID and has been shown to directly inhibit human coronaviruses in the lab," says Dr. Bryan Burt, chief of thoracic surgery in the Michael E. DeBakey Department of Surgery at Baylor, says in a press release.

Burt initiated this trial and BCM is the primary site for the study, with some collaboration with Brigham and Women's. The hypothesis is that the drug will help prevent the cytokine storm that patients with COVID-19 experience that causes their health to decline rapidly, according to the release.

The study, which is funded by Novartis, plans to enroll 75 hospitalized COVID-19 patients at Baylor St. Luke's Medical Center who are not in the ICU. There will be an initial evaluation at six months but Burt expects to have the final study results in one year.

Rice University is collaborating with other Houston institutions to create the Biomedical Expert Panel, supported by Texas Policy Lab, to assist officials in long-term pandemic recovery.

"Not all agencies and decision-makers have an in-house epidemiologist or easy access to leaders in infectious disease, immunology and health communications," says Stephen Spann, chair of the panel and founding dean of the University of Houston College of Medicine, in a news release. "This panel is about equity. We must break out of our knowledge siloes and face this challenge together, with a commitment to inclusivity and openness."

The purpose of the panel is to be available as a free resource to health departments, social service agencies, school districts and other policymakers. The experts will help design efficient public health surveillance plans, advise on increasing testing capacity and access for underserved communities, and more.

"The precise trajectory of the local epidemic is difficult to predict, but we know that COVID-19 will continue to be a long-term challenge," says E. Susan Amirian, an epidemiologist who leads the TPL's health program, in the release. "Although CDC guidelines offer a good foundation, there is no one-size-fits-all approach when managing a crisis of this magnitude across diverse communities with urgent needs."

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.”
