The YMCA of Greater Houston has launched a virtual platform called HTX+. Image via HTXplus.org

It started with a Zoom class. Shelby Saylor remembers shutting the doors to the YMCA of Greater Houston on March 17, 2020, as the threat of the coronavirus pandemic surged across the city. Like the rest of the world, the executive director of healthy living had no idea when the YMCA would reopen to its community.

"How do we reach our friends and our community in a time where they are isolated and maybe a little lost?" asked Saylor.

Using a webcam, the staff at YMCA of Greater Houston began recording videos and supportive content for members within the early days of the pandemic.

"We were more concerned with getting a product out there because it was needed, and then we iterated for quality," she says.

Over time, the concept of digital programming evolved into HTX+, the YMCA of Greater Houston's new on-demand virtual platform with fitness and wellness courses and resources for all ages.

The platform has emerged at a time when digital resources have become a necessity for people to work and live. The YMCA has been a long-held bastion of community outreach, making its resources accessible to all and working to eradicate inequalities. The virtual service emerged as a solution for addressing food insecurity, racial inequities, health disparities, social isolation, and learning gaps from afar.

"It was a two-pronged process," explains Shelby. "We had to serve the immediate needs...so we looked at the gaps in our communities as well as the gaps from closing out brick-and-mortar for a period of time," she says.

From there, the YMCA answered another question: "What gaps can we fill once we are at 100 percent capacity?"

"People are going to come back at different levels," says Saylor. She describes her own uneasiness going into a crowded grocery store and feeling her heart race. "It's going to take some time [for people] to unlearn some of that social isolation," she anticipates.

HTX+ includes fitness, mindfulness, virtual personal training, and educational resources members can access from anywhere. Saylor feels the platform, available on the Houston YMCA app and online, will help enhance the Y experience even after the pandemic. She notes the interactive platform can supplement members' in-person workouts and also provide the connection to those who are not yet comfortable returning to the facility.

"It has tremendously grown with webinars where you can ask questions and be a part of more than just the content that we're all used to consuming right now," she says.

One offering that has helped members at the YMCA handle the onslaught of pandemic stress is meditations. Saylor, who says she typically prefers to be behind the camera, was proud to step out of her comfort zone to teach a midday meditation.

Programs targeted to different age groups, from children to seniors, have helped provide resources and tools to two generations with unique needs.

"I'm really proud of our ability to find stuff for younger members because there is just not that much out there," she says. The HTX Kids program has evolved to include STEM activities, sports, crafts, and learning. "Seeing all come to fruition from one Zoom video to where it is now—I couldn't be more proud," she continued.

ForeverWell, a program for members ages 55 and up, has also expanded digital opportunities to members.

"We focus on things that maybe younger communities don't have to tackle beyond your social isolation but as well as activities of daily living, balance and things they can do that will improve how they can move around, stay healthy, and stay connected," says Saylor.

The YMCA's mission to provide health equity also helps communities that are disproportionately impacted by disasters like the pandemic and recent winter storm. The organization has set up food drives and even put warming centers in place during Winter Storm Uri.

"That's what makes us not a gym. We're going to open our facility for you to come and get a hot shower, unlike a big box gym. We're going to do that because it's not about fitness; it's about making sure basic needs are met," says Saylor.

Saylor knows that communities of color as well as the senior population, who may be on a restricted income, can benefit from the tool.

"It really helps them become stronger, healthier, and attach to something. That connectedness is worth its weight in gold," she says.

The YMCA of Greater Houston adds content to HTX+ on a weekly basis, and Saylor says programming will continue to grow long after the pandemic.

"Now that people have been exposed and have integrated digital into their life, regardless of when the pandemic ends, I believe that will always be a part of our new way of life," she says.

"Digital is never final. It's going to take our whole team and our whole community to work together to continue to meet those digital needs because it's not going anywhere," she continues.

Houston wearable biosensing company closes $13M pre-IPO round

fresh funding

Wellysis, a Seoul, South Korea-headquartered wearable biosensing company with its U.S. subsidiary based in Houston, has closed a $13.5 million pre-IPO funding round and plans to expand its Texas operations.

The round was led by Korea Investment Partners, Kyobo Life Insurance, Kyobo Securities, Kolon Investment and a co-general partner fund backed by SBI Investment and Samsung Securities, according to a news release.

Wellysis reports that the latest round brings its total capital raised to about $30 million. The company is working toward a Korea Securities Dealers Automated Quotations listing in Q4 2026 or Q1 2027.

Wellysis is known for its continuous ECG/EKG monitor with AI reporting. Its lightweight and waterproof S-Patch cardiac monitor is designed for extended testing periods of up to 14 days on a single battery charge.

The company says that the funding will go toward commercializing the next generation of the S-Patch, known as the S-Patch MX, which will be able to capture more than 30 biometric signals, including ECG, temperature and body composition.

Wellysis also reports that it will use the funding to expand its Houston-based operations, specifically in its commercial, clinical and customer success teams.

Additionally, the company plans to accelerate the product development of two other biometric products:

  • CardioAI, an AI-powered diagnostic software platform designed to support clinical interpretation, workflow efficiency and scalable cardiac analysis
  • BioArmour, a non-medical biometric monitoring solution for the sports, public safety and defense sectors

“This pre-IPO round validates both our technology and our readiness to scale globally,” Young Juhn, CEO of Wellysis, said in the release. “With FDA-cleared solutions, expanding U.S. operations, and a strong AI roadmap, Wellysis is positioned to redefine how cardiac data is captured, interpreted, and acted upon across healthcare systems worldwide.”

Wellysis was founded in 2019 as a spinoff of Samsung. Its S-Patch runs off of a Samsung Smart Health Processor. The company's U.S. subsidiary, Wellysis USA Inc., was established in Houston in 2023 and was a resident of JLABS@TMC.

Elon Musk vows to launch solar-powered data centers in space

To Outer Space

Elon Musk vowed this week to upend another industry just as he did with cars and rockets — and once again he's taking on long odds.

The world's richest man said he wants to put as many as a million satellites into orbit to form vast, solar-powered data centers in space — a move to allow expanded use of artificial intelligence and chatbots without triggering blackouts and sending utility bills soaring.

To finance that effort, Musk combined SpaceX with his AI business on Monday, February 2, and plans a big initial public offering of the combined company.

“Space-based AI is obviously the only way to scale,” Musk wrote on SpaceX’s website, adding about his solar ambitions, “It’s always sunny in space!”

But scientists and industry experts say even Musk — who outsmarted Detroit to turn Tesla into the world’s most valuable automaker — faces formidable technical, financial and environmental obstacles.

Feeling the heat

Capturing the sun’s energy from space to run chatbots and other AI tools would ease pressure on power grids and cut demand for sprawling computing warehouses that are consuming farms and forests and vast amounts of water to cool.

But space presents its own set of problems.

Data centers generate enormous heat. Space seems to offer a solution because it is cold. But it is also a vacuum, trapping heat inside objects in the same way that a Thermos keeps coffee hot using double walls with no air between them.

“An uncooled computer chip in space would overheat and melt much faster than one on Earth,” said Josep Jornet, a computer and electrical engineering professor at Northeastern University.

One fix is to build giant radiator panels that glow in infrared light to push the heat “out into the dark void,” says Jornet, noting that the technology has worked on a small scale, including on the International Space Station. But for Musk's data centers, he says, it would require an array of “massive, fragile structures that have never been built before.”

Floating debris

Then there is space junk.

A single malfunctioning satellite breaking down or losing orbit could trigger a cascade of collisions, potentially disrupting emergency communications, weather forecasting and other services.

Musk noted in a recent regulatory filing that he has had only one “low-velocity debris generating event" in seven years running Starlink, his satellite communications network. Starlink has operated about 10,000 satellites — but that's a fraction of the million or so he now plans to put in space.

“We could reach a tipping point where the chance of collision is going to be too great," said University at Buffalo's John Crassidis, a former NASA engineer. “And these objects are going fast -- 17,500 miles per hour. There could be very violent collisions."

No repair crews

Even without collisions, satellites fail, chips degrade, parts break.

Special GPU graphics chips used by AI companies, for instance, can become damaged and need to be replaced.

“On Earth, what you would do is send someone down to the data center," said Baiju Bhatt, CEO of Aetherflux, a space-based solar energy company. "You replace the server, you replace the GPU, you’d do some surgery on that thing and you’d slide it back in.”

But no such repair crew exists in orbit, and those GPUs in space could get damaged due to their exposure to high-energy particles from the sun.

Bhatt says one workaround is to overprovision the satellite with extra chips to replace the ones that fail. But that’s an expensive proposition given they are likely to cost tens of thousands of dollars each, and current Starlink satellites only have a lifespan of about five years.

Competition — and leverage

Musk is not alone trying to solve these problems.

A company in Redmond, Washington, called Starcloud, launched a satellite in November carrying a single Nvidia-made AI computer chip to test out how it would fare in space. Google is exploring orbital data centers in a venture it calls Project Suncatcher. And Jeff Bezos’ Blue Origin announced plans in January for a constellation of more than 5,000 satellites to start launching late next year, though its focus has been more on communications than AI.

Still, Musk has an edge: He's got rockets.

Starcloud had to use one of his Falcon rockets to put its chip in space last year. Aetherflux plans to send a set of chips it calls a Galactic Brain to space on a SpaceX rocket later this year. And Google may also need to turn to Musk to get its first two planned prototype satellites off the ground by early next year.

Pierre Lionnet, a research director at the trade association Eurospace, says Musk routinely charges rivals far more than he charges himself —- as much as $20,000 per kilo of payload versus $2,000 internally.

He said Musk’s announcements this week signal that he plans to use that advantage to win this new space race.

“When he says we are going to put these data centers in space, it’s a way of telling the others we will keep these low launch costs for myself,” said Lionnet. “It’s a kind of powerplay.”

Johnson Space Center and UT partner to expand research, workforce development

onward and upward

NASA’s Johnson Space Center in Houston has forged a partnership with the University of Texas System to expand collaboration on research, workforce development and education that supports space exploration and national security.

“It’s an exciting time for the UT System and NASA to come together in new ways because Texas is at the epicenter of America’s space future. It’s an area where America is dominant, and we are committed as a university system to maintaining and growing that dominance,” Dr. John Zerwas, chancellor of the UT System, said in a news release.

Vanessa Wyche, director of Johnson Space Center, added that the partnership with the UT System “will enable us to meet our nation’s exploration goals and advance the future of space exploration.”

The news release noted that UT Health Houston and the UT Medical Branch in Galveston already collaborate with NASA. The UT Medical Branch’s aerospace medicine residency program and UT Health Houston’s space medicine program train NASA astronauts.

“We’re living through a unique moment where aerospace innovation, national security, economic transformation, and scientific discovery are converging like never before in Texas," Zerwas said. “UT institutions are uniquely positioned to partner with NASA in building a stronger and safer Texas.”

Zerwas became chancellor of the UT System in 2025. He joined the system in 2019 as executive vice chancellor for health affairs. Zerwas represented northwestern Ford Bend County in the Texas House from 2007 to 2019.

In 1996, he co-founded a Houston-area medical practice that became part of US Anesthesia Partners in 2012. He remained active in the practice until joining the UT System. Zerwas was chief medical officer of the Memorial Hermann Hospital System from 2003 to 2008 and was its chief physician integration officer until 2009.

Zerwas, a 1973 graduate of the Houston area’s Bellaire High School, is an alumnus of the University of Houston and Baylor College of Medicine.
