University of Houston College of Optometry Professor John O’Brien has received a $2.6 million grant from the National Eye Institute to continue his research on the retina and neurological functions.

O’Brien is considered a leading expert in retinal neuroscience with more than 20 years of research in the field. The new funding will allow O’Brien and his team to continue to study the dense assembly of proteins associated with electrical synapses, or gap junctions, in the retina.

Gap junctions transfer electrical signals between neurons. And the plasticity of gap junctions changes the strength of a synapse, in turn changing how visual information is processed. Previous research has shown that reduced functions of electrical synapses could be linked to autism, while their hyperfunction may lead to seizures.

“The research we propose will significantly advance our understanding of the molecular complexes that control the function of electrical synapses,” O’Brien said in a news release.

The team at UH will work to identify the proteins and examine how they impact electrical synapses. It is particularly interested in the Connexin 36, or Cx36, protein. According to O’Brien, phosphorylation of Cx36, a short-term chemical modification of the protein, serves as a key driver of plasticity. And the protein has been linked to refractive error development, which is one of the largest vision problems in the world today.

Additionally, OBrien’s research has shown that plasticity is essential for all-day vision, allowing the retina to adjust sensitivity and sharpen images. He has also built a catalog of the core set of proteins surrounding electrical synapses that are conserved across species. His research has been funded by the NEI since 2000.

Houston organization is providing access to special education resources 'anywhere there is Wi-Fi'

Autism Awareness Month

A Houston-based online platform is hoping to provide easy access to special education resources to support individuals with special needs, as well as their employers, teachers, and caregivers — or anyone with internet access.

The online program, Incuentro, launched April 1, coinciding with the start of Autism Awareness Month. The first 15 classes are slated to go live in June. These virtual classes are intended to be a resource for people from first grade all the way through adulthood who are coping with Autism, ADD, Asperger's, social anxiety, or learning differences.

"Over 30 students participated in the pilot program over the past 9 months," says Wendy Dawson, founder of Incuentro. "I've seen students relate to the lessons, make connections with the topics, engage in peer conversation, and find support and learning in a safe environment."

Students learn and practice skills applicable to school, employment, and social situations in the virtual company of a qualified teacher and peers from the comfort of their own home. The teaching style is as interactive as possible and requires participants to engage in discussion.

Life education
Dawson says that students will get the most out of this experience if they are verbal, able to sustain attention, and participate in a video conference forum. Hour-long classes focus on friendship, behavior, social interactions in the primary and elementary years, while tweens focus on making peer connections.

"We want to provide help upfront to reduce the anxiety and depression that we commonly see later in life," Dawson says.

Teen classes set up students with skills for future employment and transitions post-high school. Adult learners benefit from job skills and workplace behavior norms.

Students who are employed or looking for employment learn about topics like conversing with coworkers and supervisors, appropriate social interactions, and understanding the rules of the workplace. Equally important, teachers discuss with participants ways that they can be their own advocate as they maneuver through society.

A focus on inclusion
Incuentro offers employer training as well, to help foster a climate of inclusion in the workplace, to discourage a lowering of expectations when accommodating employees with Autistic traits. Classes give supervisors understanding and practicalities that will foster a positive environment for employees who are also enrolled in the course.

"Employers are coached on topics such as: understanding a literal mind, being factual, making simple accommodations like visual schedules, delivering information in a low-stress manner, and understanding learning styles," Dawson says.

Incuentro helps to bridge the gap between the service and people in need through technology.

"There is a huge disconnect between the people who need services, and the actual resources. Many times they don't know where to go, or are too far away to access them."

All you need is internet access
Accessing the classes remotely removes the barrier of accessibility for people in rural areas, as well as people who would rather not drive to a class after a long day at work or school. Oftentimes, students will feel more comfortable participating in a one-hour, online discussion with 5-7 peers, rather than enduring the social pressures of a classroom setting.

"Our desire is to bring access to special education expertise to anywhere there is Wi-Fi," says Dawson.

Incuentro curriculum is created by Education Visionary Specialist Brandi Timmons, a Board Certified Behavior Analyst (BCBA) and a Licensed Behavior Analyst (LBA). Classes are taught by expert teachers who specialize in special needs education.

Family business
Dawson's passion behind Incuentro was inspired by her step-son, Cameron Dawson, who was diagnosed with Autism at the age of two.

"There were no services to fit his needs available in the market," Dawson says, "so we've spent 10 years advocating and learning, and figuring out how to best bring services to people who need them."

Cameron participated in the Incuentro pilot program while attending Texas Tech, and in May he will be graduating with his degree in Communication Studies. Upon returning home to Houston, he will be seeking a job in one of many local churches, where Dawson says he has experienced love and support throughout his life.

As a mother of a child with Autism and advocate for people with special needs, Dawson has seen the challenges faced by parents. Parents not only must navigate the ups and downs of school life and home life with their child each step of the way, but also plan next steps past high school graduation, and long-term care, if necessary. Incuentro helps to facilitate the discussion and provide resources for caregivers wanting to learn what options are available.

With April designated as Autism Awareness Month, Incuentro seeks to partner with organizations serving special needs populations, such as school districts, health clinics, or Autism support networks, and reach the people who need it most. Incuentro has pledged to donate a portion of its profits to a Houston non-profit that offers in-person classes for people with special needs, Social Motion. At its heart, Incuentro intends to be an answer to the question: how do we set individuals with special needs up for success, and help give them the tools to live an independent and fulfilling life?

Houston medtech startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization

Texas still ranks as No. 1 in U.S. for inbound moves, but growth dips

by the numbers

Texas continues to be the country’s No. 1 magnet for newcomers from other states, giving a boost to the state’s economy. However, Texas’ appeal weakened in 2024 compared with the previous year, due in large part to spiking home prices.

An analysis of U.S. Census Bureau data by self-storage platform StorageCafe shows Texas saw net interstate migration of 76,000 people in 2024. Texas’ net interstate migration dropped nearly 50 percent from 2023, according to the analysis. Net migration refers to the number of incoming residents minus the number of outgoing residents.

California remained the top source of newcomers for Texas, sending nearly 77,000 residents to the Lone Star State in 2024, the analysis says. Florida ranked second, followed by New York, Colorado and Illinois.

“These trends reveal Texas’ continued pull from both high-cost coastal markets and other large Sun Belt states, resulting in a mix of affordability-driven and job-driven relocation,” StorageCafe says.

Putting a damper on the influx of new residents: a roughly 124 percent surge in Texas home prices over the past decade, according to StorageCafe.

“While the state remains significantly more affordable than California, its top feeder state, the once-wide pricing gap has narrowed,” says StorageCafe. “For many movers, Texas is still a relative bargain, but no longer an undisputed one.”

Nonetheless, Texas keeps attracting young, highly educated people, which bodes well for the state’s long-term economic outlook, StorageCafe says. More than half of new arrivals to Texas in 2024 held at least a bachelor’s degree, and the age of newcomers averaged 32.

Where are most of these young, highly educated newcomers settling?

Lloyd Potter, former Texas state demographer, tells StorageCafe that population growth in Texas is happening most rapidly in suburban “ring counties” at the expense of slowing growth in urban cores. Ring counties are on the outskirts of major metro areas.

“Many people are moving from urban cores to suburban rings seeking lower costs, newer housing, better schools, and more space,” Potter says. “Typically, a move to a suburban county will be within commuting or hybrid‑commuting distance of major metro economies.”

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”
