A team of Rice University engineers has developed an implantable probe over a hundred times smaller than the width of a hair that aims to help develop better treatments for spinal cord disease and injury.

Detailed in a recent study published in Cell Reports, the probe or sensor, known as spinalNET, is used to explore how neurons in the spinal cord process sensation and control movement, according to a statement from Rice. The research was supported by the National Institutes of Health, Rice, the California-based Salk Institute for Biological Studies, and the philanthropic Mary K. Chapman Foundation based in Oklahoma.

The soft and flexible sensor was used to record neuronal activity in freely moving mice with high resolution for multiple days. Historically, tracking this level of activity has been difficult for researchers because the spinal cord and its neurons move so much during normal activity, according to the team.

“We developed a tiny sensor, spinalNET, that records the electrical activity of spinal neurons as the subject performs normal activity without any restraint,” Yu Wu, a research scientist at Rice and lead author of the study said in a statement. “Being able to extract such knowledge is a first but important step to develop cures for millions of people suffering from spinal cord diseases.”

The team says that before now the spinal cord has been considered a "black box." But the device has already helped the team uncover new findings about the body's rhythmic motor patterns, which drive walking, breathing and chewing.

"Some (spinal neurons) are strongly correlated with leg movement, but surprisingly, a lot of neurons have no obvious correlation with movement,” Wu said in the statement. “This indicates that the spinal circuit controlling rhythmic movement is more complicated than we thought.”

The team said they hope to explore these findings further and aim to use the technology for additional medical purposes.

“In addition to scientific insight, we believe that as the technology evolves, it has great potential as a medical device for people with spinal cord neurological disorders and injury,” Lan Luan, an associate professor of electrical and computer engineering at Rice and a corresponding author on the study, added in the statement.

Rice researchers have developed several implantable, minimally invasive devices to address health and mental health issues.

In the spring, the university announced that the United States Department of Defense had awarded a four-year, $7.8 million grant to the Texas Heart Institute and a Rice team led by co-investigator Yaxin Wang to continue to break ground on a novel left ventricular assist device (LVAD) that could be an alternative to current devices that prevent heart transplantation.

That same month, the university shared news that Professor Jacob Robinson had published findings on minimally invasive bioelectronics for treating psychiatric conditions. The 9-millimeter device can deliver precise and programmable stimulation to the brain to help treat depression, obsessive-compulsive disorder and post-traumatic stress disorder.

Rice University launches hub in India to drive education, tech innovation abroad

global mission

Rice University is launching Rice Global India, which is a strategic initiative to expand India’s rapidly growing education and technology sectors.

“India is a country of tremendous opportunity, one where we see the potential to make a meaningful impact through collaboration in research, innovation and education,” Rice President Reginald DesRoches says in a news release. “Our presence in India is a critical step in expanding our global reach, and we are excited to engage more with India’s academic leaders and industries to address some of the most pressing challenges of our time.”

The new hub will be in the country’s third-largest city and the center of the country’s high-tech industry, Bengaluru, India, and will include collaborations with top-tier research and academic institutions.

Rice continues its collaborations with institutions like the Indian Institute of Technology (IIT) Kanpur and the Indian Institute of Science (IISc) Bengaluru. The partnerships are expected to advance research initiatives, student and faculty exchanges and collaborations in artificial intelligence, biotechnology and sustainable energy.

India was a prime spot for the location due to the energy, climate change, artificial intelligence and biotechnology studies that align with Rice’s research that is outlined in its strategic plan Momentous: Personalized Scale for Global Impact.

“India’s position as one of the world’s fastest-growing education and technology markets makes it a crucial partner for Rice’s global vision,” vice president for global at Rice Caroline Levander adds. “The U.S.-India relationship, underscored by initiatives like the U.S.-India Initiative on Critical and Emerging Technology, provides fertile ground for educational, technological and research exchanges.”

On November 18, the university hosted a ribbon-cutting ceremony in Bengaluru, India to help launch the project.

“This expansion reflects our commitment to fostering a more interconnected world where education and research transcend borders,” DesRoches says.

UH-backed project secures $3.6M to transform CO2 into sustainable fuel with cutting-edge tech

funds granted

A University of Houston-associated project was selected to receive $3.6 million from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy that aims to transform sustainable fuel production.

Nonprofit research institute SRI is leading the project “Printed Microreactor for Renewable Energy Enabled Fuel Production” or PRIME-Fuel, which will try to develop a modular microreactor technology that converts carbon dioxide into methanol using renewable energy sources with UH contributing research.

“Renewables-to-liquids fuel production has the potential to boost the utility of renewable energy all while helping to lay the groundwork for the Biden-Harris Administration’s goals of creating a clean energy economy,” U.S. Secretary of Energy Jennifer M. Granholm says in an ARPA-E news release.

The project is part of ARPA-E’s $41 million Grid-free Renewable Energy Enabling New Ways to Economical Liquids and Long-term Storage program (or GREENWELLS, for short) that also includes 14 projects to develop technologies that use renewable energy sources to produce sustainable liquid fuels and chemicals, which can be transported and stored similarly to gasoline or oil, according to a news release.

Vemuri Balakotaiah and Praveen Bollini, faculty members of the William A. Brookshire Department of Chemical and Biomolecular Engineering, are co-investigators on the project. Rahul Pandey, is a UH alum, and the senior scientist with SRI and principal investigator on the project.

Teams working on the project will develop systems that use electricity, carbon dioxide and water at renewable energy sites to produce renewable liquid renewable fuels that offer a clean alternative for sectors like transportation. Using cheaper electricity from sources like wind and solar can lower production costs, and create affordable and cleaner long-term energy storage solutions.

“As a proud UH graduate, I have always been aware of the strength of the chemical and biomolecular engineering program at UH and kept myself updated on its cutting-edge research,” Pandey says in a news release. “This project had very specific requirements, including expertise in modeling transients in microreactors and the development of high-performance catalysts. The department excelled in both areas. When I reached out to Dr. Bollini and Dr. Bala, they were eager to collaborate, and everything naturally progressed from there.”

The PRIME-Fuel project will use cutting-edge mathematical modeling and SRI’s proprietary Co-Extrusion printing technology to design and manufacture the microreactor with the ability to continue producing methanol even when the renewable energy supply dips as low as 5 percent capacity. Researchers will develop a microreactor prototype capable of producing 30 MJe/day of methanol while meeting energy efficiency and process yield targets over a three-year span. When scaled up to a 100 megawatts electricity capacity plant, it can be capable of producing 225 tons of methanol per day at a lower cost. The researchers predict five years as a “reasonable” timeline of when this can hit the market.

“What we are building here is a prototype or proof of concept for a platform technology, which has diverse applications in the entire energy and chemicals industry,” Pandey continues. “Right now, we are aiming to produce methanol, but this technology can actually be applied to a much broader set of energy carriers and chemicals.”

Houston innovator drives collaboration, access to investment with female-focused group

HOUSTON INNOVATORS PODCAST EPISODE 262

After working in technology in her home country of Pakistan, Samina Farid, who was raised in the United States, found her way to Houston in the '70s where business was booming.

She was recruited to work at Houston Natural Gas — a company that would later merge and create Enron — where she rose through the ranks and oversaw systems development for the company before taking on a role running the pipelines.

"When you're in technology, you're always looking for inefficiencies, and you always see areas where you can improve," Farid says on the Houston Innovators Podcast, explaining that she moved on from Enron in the mid-'80s, which was an exciting time for the industry.

"We had these silos of data across the industry, and I felt like we needed to be communicating better, having a good source of data, and making sure we weren't continuing to have the problems we were having," she says. "That was really the seed that got me started in the idea of building a company."

She co-founded Merrick Systems, a software solutions business for managing oil and gas production, with her nephew, and thus began her own entrepreneurial journey. She came to another crossroads in her career after selling that business in 2014 and surviving her own battle with breast cancer.

"I got involved in investing because the guys used to talk about it — there was always men around me," Farid says. "I was curious."

In 2019, she joined an organization called Golden Seeds. Founded in 2005 in New York, the network of angel investors funding female-founded enterprises has grown to around 280 members across eight chapters. Suzan Deison, CEO of the Houston Women's Chamber, was integral in bringing the organization to Houston, and now Farid leads it as head of the Houston Chapter of Golden Seeds.

For Farid, the opportunity for Houston is the national network of investors — both to connect local female founders to potential capital from coast to coast and to give Houston investors deal flow from across the country.

"It was so hard for me to get funding for my own company," Farid says. "Having access to capital was only on the coasts. Software and startups was too risky."

Now, with Golden Seeds, the opportunity is there — and Farid says its an extremely collaborative investor network, working with local organizations like the Houston Angel Network and TiE Houston.

"With angel investing, when we put our money in, we want these companies to succeed," she says."We want more people to see these companies and to invest in them. We're not competing. We want to work with others to help these companies succeed."
