Artificial intelligence in the health care setting has a lot of potential, and one Houston institution is looking into one particular use.

Researchers at Baylor College of Medicine’s Human Genome Sequencing Center have trained an AI assistant to explain genetic test results to patients. According to findings published in the Journal of the American Medical Informatics Association (JAMIA), the team has developed generative AI to understand and interpret genetic tests. They have also tested its accuracy against Open AI’s ChatGPT 3.5.

“We created a chatbot that can provide guidance on general pharmacogenomic testing, dosage implications, and the side effects of therapeutics, and address patient concerns,” explains first author Mullai Murugan in a press release. Murugan is director of software engineering and programming at the Human Genome Sequencing Center. “We see this tool as a superpowered assistant that can increase accessibility and help both physicians and patients answer questions about genetic test results.”

The initial chatbot training specifically targeted pharmacogenomic testing for statins, meaning a patient’s potential response to cholesterol-lowering drugs, as dictated by genetics.

Murugan explains why they decided to create their own chatbot in the key publication on statin pharmacogenomics was published in May 2022, four months after the training cutoff date for ChatGPT 3.5 in January 2022. Alternatively, her team’s technology uses Retrieval Augmented Generation (RAG) and was trained on the most recent guidelines.

How did the two AI assistants compare? Four experts on cardiology and pharmacogenomics rated both chatbots based on accuracy, relevancy, risk management, and language clarity, among other factors. Though the AI scored similarly on language clarity, Baylor’s chatbot scored 85 percent in accuracy and 81 percent in relevancy compared to ChatGPT’s 58 percent in accuracy and 62 percent in relevancy when asked questions from healthcare providers.

“We are working to fine-tune the chatbot to better respond to certain questions, and we want to get feedback from real patients,” Murugan says. “Based on this study, it is very clear that there is a lot of potential here.” Nonetheless, Murugan emphasized that there is much work still to be done before the program is ready for clinical applications. That includes training the chatbot to explain results in the language used by genetic counselors. Funds from the NIH’s All of Us Research Program helped to make the research possible.

Houston startup hopes to revolutionize the chatbot business

chatterboxes

It seems like every other webpage nowadays has a virtual assistant that pops up via a chat box. A Houston startups is hoping to ride the wave of this digital marketing initiative.

Houston-based alive5 has created a platform that allows small-to-medium-sized businesses to engage customers using Chatbot Technology, from their websites, apps, SMS text-message, and social media pages.

"What we do at alive5 is really simple," says Glenn Gutierrez, COO and co-founder of alive5. "We help your business make more conversations."

Gutierrez and his co-founder Dustin Yu started out in 2017 as Alive Chat System and they were one of the first chat systems in Texas.

"Our chat system was kind of a common system that you might see on a website that says, 'Hey, how can I help you today?" says Gutierrez. "And when you press that button, somebody on the other end sends a message and says, 'Hey, how are you doing today? How can I help you?"

After exploring how to take the company, which was initially a lifestyle product, to scale, they added new products and found new ways for their clients to have more conversations with their customers.

"We had to create as many channels as possible outside of web chat," says Gutierrez. "We talked about the live chat system, moving into SMS text message, moving into social media and interestingly enough, we started moving into business cards with QR codes where people can actually scan a QR code or text a phone number and we can automatically build a relationship with a customer at an event, in person or from a billboard.

"And that activates pretty much all the rest of the system for businesses to be able to engage a customer. So we think about ourselves as the best way to help you create more conversations, not just on your website, but pretty much anywhere you would engage a customer."

The platform enjoyed a meteoric rise in the chat space due to its participation in Capital Factory's accelerator program. From there, they were placed in another accelerator program in Philadelphia, the Comcast NBCUniversal LIFT Labs Accelerator, powered by Techstars.

"Because of the boost from the accelerator programs, we developed relationships with a lot of great organizations," says Gutierrez. "Today, we service over 800 customers, including 200 of the top college sports teams and pro teams like the NBA, NFL and NHL."

The platform's collaboration helps teams sell more tickets, especially premium seat tickets, by facilitating conversations with VIP clients and allowing fans the opportunity to go to the team's website to use the automated chat solution.

"A good example of one of those is the Jacksonville Jaguars website," says Gutierrez. "You can go there and see one of our chat boxes available to assist with inquiries or questions that you may have before, during or after a game. And our solution is built for organizations with a high volume of customer interactions to automate some of those tier one questions."

Alive5 also services customers like Royal Caribbean Cruise Line, major hotel brands and other companies in the hospitality space. They are also now collaborating with Spectra Venue Management, which manages hundreds of venues throughout North America, to pilot alive5's messaging and concierge services.

Outside of their inroads in the chat space, the platform is creating AI-powered strategies to help companies maximize their communication opportunities at personal touchpoint events such as conferences and trade shows.

"With our A.I. powered business cards, we're able to take an engagement that happens at a conference, an event or at a networking session and turn that into a prospect that's now part of a company's digital lead funnel," says Gutierrez. "What we're proposing is to give them a laser-etched metal business card with the QR code. That is better than just giving them a paper business card that they will take and may or may not call you and that's it, that's the end of the interaction.

"With the QR code, a potential contact can scan it and it will send them a demo of our product to their phone and it will give them all of a client's contact details so they can reach out to that client anytime they're ready to buy. The best part about that is that now you have something that no other system can do and you have that customer's phone number available to you at any point in time."

Moving forward, the Houston-based platform wants to do everything within its power to be one of the most successful chat companies nationwide.

"I like to think about our product like a Lego set," says Gutierrez. "It's up to you to choose what package you want. I've been in the startup space for a long time and to finally see that ecosystem starting to mature to the point that businesses are more open to digitally transforming their organizations, where they're understanding the need to take risks, to try new things, that's great for us.

"When you think about a company that can help you with your communication, I want alive5 to be the first company on their minds."

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.”
