Researchers across the world are coming up with innovative breakthroughs regarding the coronavirus, but Houston research institutions are also making health and wellness discoveries outside of COVID-19.

Here are three from Houston researchers from a muscular atrophy study from outer space to a research project that might allow blind patients to "see."

Houston Methodist researcher Alessandro Grattoni and his team published research on muscular atrophy in astronauts. The research was published in Advanced Therapeutics and focused on his 2017 RR-6 muscle atrophy study that was conducted on the International Space Station.

While the current standard practice for astronauts maintaining their muscles is working out over two hours a day, the research found that use of drugs could also help preserve muscles. On a SpaceX refuel mission, mice that were implanted with a "Nanofluidic Delivery System" were sent up to space and monitored, according to a report. The device gradually released small doses of formoterol, an FDA approved drug for use in bronchodilation that has also been shown to stimulate increased muscle mass.

University of Houston researchers are looking into the way the body responds to fear in order to enhance mental health treatment. Rose Faghih, assistant professor of electrical and computer engineering, and doctoral student Dilranjan Wickramasuriya in the Computational Medicine Lab (CML) are leading the project.

"We developed a mixed filter algorithm to continuously track a person's level of sympathetic nervous system activation using skin conductance and heart rate measurements," writes Faghih in the journal PLOS One. "This level of sympathetic activation is closely tied to what is known as emotional arousal or sympathetic arousal."

When this sympathetic nervous system is activated — sometimes known as the "fight or flight" response — the heart beats faster and more oxygen is delivered to the muscles, according to a press release. Then, the body begins to sweat in order to cool down.

"Using measurements of the variations in the conductivity of the skin and the rate at which the heart beats, and by developing mathematical models that govern these relationships, CML researchers have illustrated that the sympathetic nervous system's activation level can be tracked continuously," reports Faghih.

This algorithm could be used in a wearable electronic device that could be worn by a patient diagnosed with a fear or anxiety disorder.

When someone loses their vision, it's likely due to damage to the eyes or optic nerve. However, the brain that interprets what they eyes sees, works perfectly fine. But researchers from Baylor College of Medicine have worked on a thesis that a device with a camera could be designed and implemented to do the seeing for the blind patient.

"When we used electrical stimulation to dynamically trace letters directly on patients' brains, they were able to 'see' the intended letter shapes and could correctly identify different letters," says Dr. Daniel Yoshor, professor and chair of neurosurgery in a press release. "They described seeing glowing spots or lines forming the letters, like skywriting."

Through a study supported by the National Eye Institute with both sighted and blind people using implanted devices, the investigators determined that the process was promising. According to the release, the researchers identified several obstacles must be overcome before this technology could be implemented in clinical practice.

"The primary visual cortex, where the electrodes were implanted, contains half a billion neurons. In this study we stimulated only a small fraction of these neurons with a handful of electrodes," says said Dr. Michael Beauchamp, professor and in neurosurgery, in the release.

"An important next step will be to work with neuroengineers to develop electrode arrays with thousands of electrodes, allowing us to stimulate more precisely. Together with new hardware, improved stimulation algorithms will help realize the dream of delivering useful visual information to blind people."

Building Houston

Is the Space City poised to continue its reign as an innovative hub for space exploration? All signs point to yes, according to a group of experts.

The Greater Houston Partnership hosted its annual State of Space this week. The virtual event featured a keynote address from Vanessa Wyche, director of NASA Johnson Space Center, and a panel moderated by David Alexander, chair of aerospace and aviation committee at the GHP and the director of the Rice Space Institute.

The conversations focused on the space innovation activity happening in Houston, as well as an update on the industry as a whole has space commercialization continues to develop. All the speakers addressed how Houston has what it takes to remain a hub for the sector.

"The future looks very bright for Houston that we will remain a leader in Houston spaceflight," Wyche says in her address.

Here are a few other memorable moments from the event.

"Houston, I feel, is poised to be a leader. We have led in human space flight, and we will a leader in commercialization."

— Wyche says in her keynote address, which gave a thorough overview of what all NASA is working on at JSC. She calls out specifically how startups are a driving force in commercialization. JSC is working with local accelerator programs at The Ion and MassChallenge.

"These startups help us to connect to tomorrow's space innovation leaders, and gives our team the opportunity to mentor these entrepreneurs as we work to advance both our scientific and technical knowledge," she says.

"The ability to have a place where government, academia, and industry can come together and share ideas and innovation is incredibly powerful."

​— Steve Altemus, president and CEO of Intuitive Machines LLC, specifically talking about the Houston Spaceport, where Intuitive Machines has signed on as a tenant. Altemus adds that a major key to leading space commercialization is a trained workforce, which the spaceport is focused on cultivating.

"We shouldn't discount the character that Houston has from the standpoint as a great place to build a business."

— Tim Kopra, vice president of robotics and space at MDA Ltd., says, adding that Houston is a big city that feels like a small town. "We need to incentivize companies to come and stay," he says.

"Great cities — like great companies — understand that if you're still, you're probably moving backwards. ... I think Houston gets it in that regard."

— Todd May, senior vice president of science and space at KBR, says, adding that Houston realizes it needs to be on the offensive side to bring innovation to the game, positioning the city very well for the future.
