The Houston toad is a species that was discovered in Harris County in the 1950s. It has a very distinct, loud call that reverberates at quite a high pitch. But the Houston toad's call hasn't been heard in the city of Houston for almost 50 years. The species is locally extinct and critically endangered elsewhere. In fact, it's the most endangered amphibian in North America, says Cassidy Brown Johnson, a Rice University lecturer and president of the Coastal Prairie Partnership.

"When we think about extinction, we think of the dodo bird or the woolly mammoth," Johnson says. "But extinction is happening right underneath our noses."

The Houston Zoo has a breeding facility for Houston toad, but other than that, it's extremely unlikely that the Houston toad will ever reside naturally in its namesake city.

"We have modified the environment so heavily, that it'd be a bit of a dicey thing to do [to reintroduce the species] because there are so few of them, it's better to focus on an environment where it's still OK for them," Johnson says. The largest population of the Houston toad is actually in Bastrop, however due to the Bastrop fires in 2011, the species is only just recently back to a good place even there.

Johnson is giving a free lecture in April at Rice regarding extinction, where she'll bring her Astros-named Houston toads, Springer and Julia Morales, as her teacher aids.

Changing tides in conservation
As cities like Houston continue to be developed, scientists and researchers are challenged with finding new ways to effect conservation. Johnson says within the industry, there's been a shift in thinking when it comes to preserving nature.

"There's a new burgeoning movement in conservation called urban conservation," she says. "For a long time, if you talked to the traditional conservationists, the idea of conservation is to protect big spaces — the national and state park systems are the perfect example."

But large parks are expensive and a huge undertaking. It's still the strongest form of conservation, but introducing conservation efforts in a city — perhaps in some of Houston's parks, like Memorial Park or Hermann Park — helps not only the species of animals involved, but also educates the local population and forms a connection with residents.

"That has a twofold kind of benefit," Johnson says. "It protects the greenspace so species to live with us, and then also it makes the connection to this place we try to protect."

Of course, this type of effort is new, and there's not a lot of data to show how this would affect the ecosystem and its species, from the migratory and genetic diversity standpoints. Despite the lack of data, Johnson says this type of effort needs to happen.

"We're going to continue to manipulate the world, and maybe if we started thinking about this now, that we can get to a point were we understand enough were we can make these some sort of functioning ecosystem," she says.

Part of the shift in thinking about these ecosystems has to do with new ways of tracking species and understanding their environments.

"Technology is helping us ask a lot of these questions," Johnson says. "Ecology is surprisingly complicated. There's so many variables. ... I think technology and our advance with computing is definitely going to help us understand it."

Using preservation to solve flooding
The educational component is also very important to conservation, and Johnson is making strides on campus with her class. Last year, her department and her class introduced a pocket prairie right on the Rice campus.

Before it was the fourth largest city in America, Houston was a prairie. That type of ecosystem — thick with prairie grass — is very absorbing when it comes to rain water.

"It's really surprising to people that the trees and all this lushness is actually all artificial," Johnson says. "We know that this ecosystem evolved with the cyclical flooding events that happened here."

This movement to bring back Houston's ancient ecosystem is a new focus on a few prairie conservationist groups — and even the Harris County Flood Control. This has been going on for a while, but recent flooding events have opened the eyes of people now looking for reliable solutions to flooding problems.

"After Hurricane Harvey, people started realizing that this might be one of the solutions we could actually investigate and see if it can help us," Johnson says. "A green space is going to absorb way more water than a parking lot."

Of course, there are other flood solutions being discussed — some even incorporating tech or even a tube system underground.

"Historically, there has been some budding of heads between the environment and technology, but I really think moving forward, those two fields have to work together. We need to use technology to save the environment," Johnson says. "I think Houston is one of the places where that conversation is starting to happen."

Houston professor awarded $2.6M grant for retina, neurological research

seeing green

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.

Capwell Services

Houston-based methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the US and Canada, equivalent to more than 400 million metric tons of CO2e per year. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by current CEO Andrew Lane. It has since participated in programs with Greentown Labs and Rice Clean Energy Accelerator. The company moved to Houston in 2023 and raised a pre-seed round. It has also received federal funding from the DOE. Capwell is currently piloting its commercial unit with oil and gas operators.

According to the company, its patented DERA system can be installed quietly without heavy-lift vessels, reducing anchor-related costs by up to 75 percent and lifecycle CO2 emissions by up to 80 percent.

The company was founded in 2023 by current CEO Junho Lee and CTO Charles Aubeny. Lee earned his Ph.D. in geotechnical engineering from Texas A&M University, where Aubeny is a professor of civil and environmental engineering. The company has not raised VC funding, but has participated in numerous accelerators and incubators, including Greentown Labs, MassChallenge, EnergyTechNexus LiftOff and others. Lee is an Activate 2025 fellow.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers and rubbers. The company reports that it plans to open its first commercial plant in the next 18 months.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch and lead engineer Trey Sheridan, the company has raised just under $1 million in capital and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch and other organizations.
