The Translational Research Institute for Space Health, or TRISH, at Baylor College of Medicine announced a unique program that will work with commercial spaceflight providers and their passengers. The EXPAND — Enhancing eXploration Platforms and Analog Definition — Program will collect information and data from multiple space flights and organize it in one place. TRISH selected TrialX to build the centralized database.

"The space environment causes rapid body changes. This can help us understand how we humans react to and overcome stress. Ensuring that space explorers remain healthy pushes us to invent new approaches for early detection and prevention of medical conditions," says Dorit Donoviel, executive director at TRISH, in the release.

"Studying a broad range of people in space increases our knowledge of human biology. TRISH's EXPAND program will leverage opportunities with commercial spaceflight providers and their willing crew to open up new research horizons." Click here to read more.

Nuri Firat Ince, an associate professor of biomedical engineering at UH, has received a federal grant aimed at helping stop epileptic seizures before they start. The BRAIN Initiative at the National Institute of Neurological Disorders and Stroke awarded the $3.7 million grant to go toward Ince's work to create a seizure-halting device based on his research.

According to UH, Ince has reduced by weeks the time it takes to locate the seizure onset zone (SOZ), the part of the brain that causes seizures in patients with epilepsy. He's done this by detecting high-frequency oscillations (HFO) forming "repetitive waveform patterns" that identify their location in the SOZ.

"If the outcomes of our research in acute settings become successful, we will execute a clinical trial and run our methods with the implanted … system in a chronic ambulatory setting," Ince says. Click here to read more.

In her guest column for InnovationMap, Vanessa Wade addressed some of the challenges she faced founding a company as a person of color — specifically the lack of access to funding. In the article, she calls corporations to action to help business leaders like herself.

"The journey ahead can feel discouraging, but the good news is that now I have a much better idea of what it will take to build an equitable road back and get businesses like mine on even footing," she writes. Click here to read more.

A professor at the University of Houston has received a federal grant aimed at helping stop epileptic seizures before they start.

The BRAIN Initiative at the National Institute of Neurological Disorders and Stroke awarded the $3.7 million grant to Nuri Firat Ince, an associate professor of biomedical engineering at UH. The grant will go toward Ince's work to create a seizure-halting device based on his research.

According to UH, Ince has reduced by weeks the time it takes to locate the seizure onset zone (SOZ), the part of the brain that causes seizures in patients with epilepsy. He's done this by detecting high-frequency oscillations (HFO) forming "repetitive waveform patterns" that identify their location in the SOZ.

Ince plans to use those HFOs to help control seizures. But he first must determine whether the HFOs can be detected with an implantable closed-loop device, enabling delivery of electrical stimulation that can control seizures. The device is called a brain interchange system. A closed-loop system supplies stimulation only when it detects the onset of a seizure.

Ince's neurotechnology partner, Cortec GMBH of Freiburg, Germany, is supplying the brain interchange system. Houston's Baylor College of Medicine eventually will be the site where medical professionals implant the device in pediatric and adult epilepsy patients.

"If the outcomes of our research in acute settings become successful, we will execute a clinical trial and run our methods with the implanted … system in a chronic ambulatory setting," Ince says in a UH news release.

Research published recently in the journal AJOB Neuroscience found that a closed-loop brain implant being used to treat refractory epilepsy does not alter patients' personalities or self-perception.

"Next-generation brain stimulation devices can modulate brain activity without human intervention, which raises new ethical and policy questions," lead author Tobias Haeusermann of the University of California, San Francisco, says in a news release. "But while there is a great deal of speculation about the potential consequences of these innovative treatments, very little is currently known about patients' experiences of any device approved for clinical use."

The study, however, found no evidence that the device Haeusermann and his colleagues studied had changed patients' personalities or self-perception.

Haeusermann and his fellow researchers based their study on a closed-loop device that's currently available. In 2013, the U.S. Food and Drug Administration (FDA) approved this brain stimulation system for treatment of refractory epilepsy. It's the first clinically approved and commercially available closed-loop brain stimulation device for epilepsy patients. Refractory epilepsy occurs when medication no longer controls seizures.

According to a research article published in 2018, epilepsy ranks among the most common neurological disorders, affecting about 1% of the global population. For patients who suffer seizures that cannot be treated with drugs, a frequent treatment is surgical removal of the SOZ.

In this country, about 3 million adults and 470,000 children have epilepsy, according to the U.S. Centers for Disease Control and Prevention, including nearly 293,000 Texans. In the U.S., epilepsy is the fourth most common neurological disorder, preceded by migraine, stroke and Alzheimer's disease, the Epilepsy Foundation of Michigan says.

About 150,000 Americans are diagnosed each year with epilepsy.

Epilepsy is prevalent among people with autism, cerebral palsy, Down syndrome, and intellectual disabilities.

About 30 types of seizure occur among the more than 60 types of epilepsy, the Michigan foundation says. A seizure briefly disturbs electrical activity in the braining, causing temporary changes in movement, awareness, feelings, behavior, and other bodily functions.

Daily medication is the standard treatment for epilepsy, according to the Michigan foundation. Still, 30 percent to 40 percent of people with epilepsy continue to experience seizures.

Each year, U.S. health care costs associated with epilepsy add up to roughly $28 billion, according to the American Journal of Managed Care.

"Most people with epilepsy are able to lead productive and fulfilling lives, but for many, epilepsy can be a devastating condition," the foundation says.

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.”
