Another Houston scientist has won one of the highly competitive National Science Foundation (NSF) CAREER Awards.

Lei Li, an assistant professor of electrical and computer engineering at Rice University, has received a $550,000, five-year grant to develop wearable, hospital-grade medical imaging technology capable of visualizing deep tissue function in real-time, according to the NSF. The CAREER grants are given to "early career faculty members who demonstrate the potential to serve as academic models and leaders in research and education."

“This is about giving people access to powerful diagnostic tools that were once confined to hospitals,” Li said in a news release from Rice. “If we can make imaging affordable, wearable and continuous, we can catch disease earlier and treat it more effectively.”

Li’s research focuses on photoacoustic imaging, which merges light and sound to produce high-resolution images of structures deep inside the body. It relies on pulses of laser light that are absorbed by tissue, leading to a rapid temperature rise. During this process, the heat causes the tissue to expand by a fraction, generating ultrasound waves that travel back to the surface and are detected and converted into an image. The process is known to yield more detailed images without dyes or contrast agents used in some traditional ultrasounds.

However, current photoacoustic systems tend to use a variety of sensors, making them bulky, expensive and impractical. Li and his team are taking a different approach.

Instead of using hundreds of separate sensors, Li and his researchers are developing a method that allows a single sensor to capture the same information via a specially designed encoder. The encoder assigns a unique spatiotemporal signature to each incoming sound wave. A reconstruction algorithm then interprets and decodes the signals.

These advances have the potential to lower the size, cost and power consumption of imaging systems. The researchers believe the device could be used in telemedicine, remote diagnostics and real-time disease monitoring. Li’s lab will also collaborate with clinicians to explore how the miniaturized technology could help monitor cancer treatment and other conditions.

“Reducing the number of detection channels from hundreds to one could shrink these devices from bench-top systems into compact, energy-efficient wearables,” Li said in the release. “That opens the door to continuous health monitoring in daily life—not just in hospitals.”

Rice University spinout lands $500K NSF grant to boost chip sustainability

cooler computing

HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.

science supported

An assistant professor at Rice University has won one of the highly competitive National Science Foundation's CAREER Awards.

The award grants $670,406 over five years to Amanda Marciel, the William Marsh Rice Trustee Chair of chemical and biomolecular engineering, to continue her research in designing branch elastomers that return to their original shape after being stretched, according to a statement from Rice. The research has applications in stretchable electronics and biomimetic tissues.

“My goal is to create a new paradigm for designing elastomers,” Marciel said in a statement. “The research has four aims: to determine the role of comb polymer topology in forming elastomers, understanding the effects of that topology on elastomer mechanics, characterizing its effects on elastomer structure and increasing the intellectual diversity in soft matter research.”

Marciel, who joined the faculty at Rice in 2019, is one of about 500 researchers to receive the NSF's CAREER Award each year. The award recognizes early-career faculty members who “have the potential to serve as academic role models in research and education and to lead advances in the mission of their department or organization,” according to the NSF.

In addition to supporting Marciel's research, the funds will also go toward creating opportunities in soft matter research for undergraduates and underrepresented scientists. It will establish a new annual symposium called the Texas Soft Matter Meeting, where community college teachers can participate in a soft matter laboratory module and students in the Research Experiences for Undergrads program at Rice will present their summer research.

Recently, Rice also launched the new Rice Synthetic Biology Institute, which aims to strengthen the synthetic biology community across disciplines at the university. It is part of an $82 million investment the university put toward synthetic biology, neuroengineering and physical biology in 2018.

A fellow team or Rice researcher is also working on wearable haptic accessories. A member of the team was recently named to the 2024 cohort of Rice Innovation Fellows. Click here to learn more.

Houston autonomous trucking co. completes first test run without human intervention

on the road

Houston-based Bot Auto, an autonomous trucking company, has completed its first test run without human assistance. Bot Auto conducted the test in Houston.

“The truck operated seamlessly within its defined operational domain with no one in the cab or remote assistance, navigating real-world traffic conditions,” the company said in a news release. “The run was executed at sunset, successfully navigating day and night operations.”

Bot Auto, a transportation-as-a-service startup, added that this milestone “serves as a validation benchmark, demonstrating the maturity and safety of Bot Auto’s autonomy stack and test protocols.”

The successful test comes two years after Xiaodi Hou, a globally recognized expert in autonomous vehicles, founded Bot Auto.

“This validation run is a meaningful step, but it’s a waypoint, not the destination,” Hou, CEO of Bot Auto, added in the release. “Success is simple: Autonomy must beat human cost-per-mile, consistently and safely. And at Bot Auto, humanless means no human — not in the driver’s seat, not in the back seat, and not behind a remote joystick.”

For several months, Bot Auto has been conducting autonomous trucking tests on a Houston-to-San Antonio route. In the coming months, Bot Auto will operate its first commercial cargo run without human assistance between its Houston and San Antonio hubs.

“Our mission is to revolutionize the transportation industry with our autonomous trucks, making a lasting positive impact on humanity,” the company says.

Last October, Bot Auto announced it had raised $20 million in pre-series A funding from Brightway Future Capital, Cherubic Ventures, EnvisionX Capital, First Star Ventures, Linear Capital, M31 Capital, Taihill Venture, Uphonest Capital, and Welight Capital.

This summer, Hou told the Front Lines podcast that Bot Auto had raised more than $45 million altogether.

Hobby debuts solar canopy as airport system reaches new sustainability milestone

solar solutions

Houston's William P. Hobby Airport is generating its own clean energy.

Houston Aiports announced that Hobby's red garage is now home to a "solar canopy" that is producing energy at 100 percent capacity to power daily operations. The photovoltaic (PV) solar system generated more than 1.1 gigawatt-hours of electricity in testing, and is expected to produce up to 1 megawatt-hour now that it's operating at full power.

“This project is proof that sustainability can be practical, visible and directly tied to the passenger experience,” Jim Szczesniak, director of aviation for Houston Airports, said in a news release. “Passengers now park under a structure that shields their cars from the Texas sun while generating clean energy that keeps airport operations running efficiently, lowering overall peak demand electrical costs during the day and our carbon footprint. It’s a win for travelers, the city and the planet.”

The project was completed by Texas A&M Engineering Experiment Station (TEES) and CenterPoint Energy. It's part of Houston Airport's efforts to reduce carbon emissions by 40 percent over its 2019 baseline.

In a separate announcement, the airport system also shared that it recently reached Level 3 in the Airports Council International (ACI) Airport Carbon Accreditation program after reducing emissions by 19 percent in three years. This includes reductions at George Bush Intercontinental Airport (IAH), Hobby and Ellington Airport/Houston Spaceport.

The reductions have come from initiatives such as adding electric vehicles to airport fleets, upgrading airfield lighting with LED bulbs, adding smarter power systems to terminals, and improving IAH's central utility plant with more efficient equipment. Additionally, the expansion to Hobby's West Concourse and renovations at IAH Terminal B incorporate cleaner equipment and technology.

According to Houston Airports, from 2019 to 2023:

  • IAH reduced emissions by 17 percent
  • Hobby reduced emissions by 32 percent
  • Ellington Airport reduced emissions by 4 percent

"I see firsthand how vital it is to link infrastructure with sustainability,” Houston City Council Member Twila Carter, chair of the council’s Resilience Committee, said in the release. “Reducing carbon emissions at our airports isn’t just about cleaner travel — it’s about smarter planning, safer communities and building a Houston that can thrive for generations to come.”

Houston health orgs lost $58M in canceled, stalled NIH grants, new report shows

research cuts

Seven institutions in the Houston area have lost nearly $60 million in grants from the National Institutes of Health (NIH) that were aimed at funding health research.

The Science & Community Impacts Mapping Project identified 37 cancelled or frozen NIH grants worth $58.7 million that were awarded to seven Houston-area institutions. The University of Texas Medical Branch at Galveston suffered the biggest loss — five grants totaling nearly $44.8 million.

The Harvard University T.H. Chan School of Public Health reported in May that over the previous several months across the U.S., the federal government had terminated roughly 2,100 NIH research grants worth around $9.5 billion.

In August, the U.S. Supreme Court derailed researchers’ efforts to reinstate almost $2 billion in research grants issued by NIH, according to Nature.com.

“Make no mistake: This was a decision critical to the future of the nation, and the Supreme Court made the wrong choice. History will look upon these mass National Institutes of Health (NIH) research grant terminations with shame,” the American Association of Medical Colleges said in a statement. “The Court has turned a blind eye to this grievous attack on science and medicine, and we call upon Congress to take action to restore the rule of law at NIH.”

Texas health researchers rely heavily on NIH grants and contracts. During the federal government’s 2024 budget year, NIH awarded $1.9 billion in grants and contracts that directly supported 30,553 jobs and more than $6.1 billion in economic activity in Texas, according to the United for Medical Research coalition.

Here’s a rundown of the cancelled and frozen NIH grants in the Houston area.

  • University of Texas Medical Branch at Galveston: Five cancelled or frozen grants, totalling approximately $44.8 million in funding lost.
  • Baylor College of Medicine: 17 grants cancelled or frozen, totalling approximately $8 million in funding lost
  • University of Houston. Five cancelled or frozen grants, totalling approximately $3.7 million in funding lost
  • University of Texas Health Science Center Houston: Five grants cancelled or frozen, totaling approximately $1.1 million in funding lost.
  • University of Texas MD Anderson Cancer Center: Two grants cancelled or frozen, totalling $831,581 in funding
  • Rice University. Two grants cancelled or frozen, totaling $254,645 in funding lost
  • Prairie View A&M University: One grant cancelled or frozen, totalling $31,771 in funding lost
