With such a dynamic virus like COVID-19 that affects patients with different levels of severity, the first challenge doctors face when treating infected patients is assessing the situation. CHI St. Luke's Health has been implementing a new technology that allows its physicians better access to that initial diagnosis.

Dr. Jose Diaz-Gomez, an anesthesiologist at CHI St. Luke's Health and ultrasonography expert, says the Butterfly iQ's portable ultrasonography technology has been a key tool in his team's point of care for COVID-19 patients. Over the past few years, ultrasonography equipment has been evolving to be more portable and more accurate. That's what the Butterfly iQ technology provides, and Diaz-Gomez says his team was quick to realize how the technology can help in diagnostics and treatment of coronavirus patients.

A traditional approach to examining a patient's lungs would mean radiography, but Diaz-Gomez says his team saw the opportunity ultrasonography and these new, portable devices had on providing more accurate and timely diagnostics.

"In conditions that are dynamic, you want to have a diagnostic tool that, over time as you're treating a patient, you can see meaningful changes — good or bad," Diaz-Gomez says. "The pandemic has enabled us to use — from the initial care to when they are on the ventilator — ultrasonography to see the changes in the patient's' lungs."

The Butterfly iQ device is different from its ultrasound predecessors in that it's built to be more accurate, portable, easy to use, and low cost (even being made available for commercial purchase). According to Diaz-Gomez, he could train someone on the device in just a few hours.

Ahead of the pandemic, CHI St. Luke's had 20 of these devices and now has doubled that initial fleet. Along with the other non-Butterfly iQ ultrasonography devices, Diaz-Gomez's team has access to 70 ultrasonography devices — 80 percent of which are dedicated to COVID-19 patients.

"Our institution was very supportive of bringing a very robust roll-out program for point-of-care ultrasonography during the pandemic," Diaz-Gomez says. "We were able to incorporate 40 ultrasound devices — the Butterfly system. Not only that, we actually implemented a very rigorous infection control process to make sure we do it in a safe manner. You don't want to bring tools that will be another source of transmission from patient to patient."

While this new technology is continuing to make a difference in St. Luke's COVID units, Diaz-Gomez is already looking forward to the difference the devices will make post pandemic.

"Whatever we will face after the pandemic, many physicians will be able to predict more objectively when a patient is deteriorating from acute respiratory failure," he says. "Without this innovation, we wouldn't have been able to be at higher standards with ultrasonography."

The device, with its portability, low cost, and ease of use, also has an application for telemedicine and at-home health, and that's something that's exciting for Diaz-Gomez. However, both in his COVID units or in the home setting, the device is only as good as the clinician who's interpreting the images paired with the other diagnostics.

"The integration of ultrasonography with the clinical practice itself — it has to go hand in hand," Diaz-Gomez says. "The clinical decision will depend on that integration."

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.
