Collaborators from two Houston universities are leading the way in engineering a biomaterial into a scalable, multifunctional material that could potentially replace plastic.

The research was led by Muhammad Maksud Rahman, an assistant professor of mechanical and aerospace engineering at the University of Houston and an adjunct assistant professor of materials science and nanoengineering at Rice University. The team shared its findings in a study in the journal Nature Communications earlier this month. M.A.S.R. Saadi, a doctoral student in material science and nanoengineering at Rice, served as the first author.

The study introduced a biosynthesis technique that aligns bacterial cellulose fibers in real-time, which resulted in robust biopolymer sheets with “exceptional mechanical properties,” according to the researchers.

Biomaterials typically have weaker mechanical properties than their synthetic counterparts. However, the team was able to develop sheets of material with similar strengths to some metals and glasses. And still, the material was foldable and fully biodegradable.

To achieve this, the team developed a rotational bioreactor and utilized fluid motion to guide the bacteria fibers into a consistent alignment, rather than allowing them to align randomly, as they would in nature.

The process also allowed the team to easily integrate nanoscale additives—like graphene, carbon nanotubes and boron nitride—making the sheets stronger and improving the thermal properties.

“This dynamic biosynthesis approach enables the creation of stronger materials with greater functionality,” Saadi said in a release. “The method allows for the easy integration of various nanoscale additives directly into the bacterial cellulose, making it possible to customize material properties for specific applications.”

Ultimately, the scientists at UH and Rice hope this discovery could be used for the “next disposable water bottle,” which would be made by biodegradable biopolymers in bacterial cellulose, an abundant resource on Earth.

Additionally, the team sees applications for the materials in the packaging, breathable textiles, electronics, food and energy sectors.

“We envision these strong, multifunctional and eco-friendly bacterial cellulose sheets becoming ubiquitous, replacing plastics in various industries and helping mitigate environmental damage,” Rahman said the release.

Houston team’s discovery brings solid-state batteries closer to EV use

A Better Battery

A team of researchers from the University of Houston, Rice University and Brown University has uncovered new findings that could extend battery life and potentially change the electric vehicle landscape.

The team, led by Yan Yao, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering at UH, recently published its findings in the journal Nature Communications.

The work deployed a powerful, high-resolution imaging technique known as operando scanning electron microscopy to better understand why solid-state batteries break down and what could be done to slow the process.

“This research solves a long-standing mystery about why solid-state batteries sometimes fail,” Yao, corresponding author of the study, said in a news release. “This discovery allows solid-state batteries to operate under lower pressure, which can reduce the need for bulky external casing and improve overall safety.”

A solid-state battery replaces liquid electrolytes found in conventional lithium-ion cells with a solid separator, according to Car and Driver. They also boast faster recharging capabilities, better safety and higher energy density.

However, when it comes to EVs, solid-state batteries are not ideal since they require high external stack pressure to stay intact while operating.

Yao’s team learned that tiny empty spaces, or voids, form within the solid-state batteries and merge into a large gap, which causes them to fail. The team found that adding small amounts of alloying elements, like magnesium, can help close the voids and help the battery continue to function. The team captured it in real-time with high-resolution videos that showed what happens inside a battery while it’s working under a scanning electron microscope.

“By carefully adjusting the battery’s chemistry, we can significantly lower the pressure needed to keep it stable,” Lihong Zhao, the first author of this work, a former postdoctoral researcher in Yao’s lab and now an assistant professor of electrical and computer engineering at UH, said in the release. “This breakthrough brings solid-state batteries much closer to being ready for real-world EV applications.”

The team says it plans to build on the alloy concept and explore other metals that could improve battery performance in the future.

“It’s about making future energy storage more reliable for everyone,” Zhao added.

The research was supported by the U.S. Department of Energy’s Battery 500 Consortium under the Vehicle Technologies Program. Other contributors were Min Feng from Brown; Chaoshan Wu, Liqun Guo, Zhaoyang Chen, Samprash Risal and Zheng Fan from UH; and Qing Ai and Jun Lou from Rice.

University of Houston archaeologists make history with Mayan tomb discovery

History in the Making

Two University of Houston archaeologists have made scientific history with the discovery of a Mayan king's tomb in Belize.

The UH team led by husband and wife scientists Arlen F. Chase and Diane Z. Chase made the discovery at Caracol, the largest Mayan archeological site in Belize, which is situated about 25 miles south of Xunantunich and the town of San Ignacio. Together with Belize's Institute of Archeology, as well as support from the Geraldine and Emory Ford Foundation and the KHR Family Fund, they uncovered the tomb of Caracol's founder, King Te K’ab Chaak. Their work used airborne light detection and ranging technology to uncover previously hidden roadways and structures that have been reclaimed by the jungle.

The tomb was found at the base of a royal family shrine. The king, who ascended the throne in 331 AD, lived to an advanced enough age that he no longer had teeth. His tomb held a collection of 11 pottery vessels, carved bone tubes, jadeite jewelry, a mosaic jadeite mask, Pacific spondylus shells, and various other perishable items. Pottery vessels found in the chamber depict a Maya ruler wielding a spear as he receives offerings from supplicants represented as deities; the figure of Ek Chuah, the Maya god of traders, surrounded by offerings; and bound captives, a motif also seen in two related burials. Additionally, two vessels had lids adorned with modeled handles shaped like coatimundi (pisote) heads. The coatimundi, known as tz’uutz’ in Maya, was later adopted by subsequent rulers of Caracol as part of their names.

During the Classical Period, Caracol was one of the main hubs of the Mayan Lowlands and covered an area bigger than that of present-day Belize City. Populations survived in the area for at least 1,000 years before the city was abandoned sometime around 900 AD. The royal dynasty established by Te K’ab Chaak continued at Caracol for over 460 years.

The find is also significant because this was roughly when the Mexican city of Teotihuacan made contact with Caracol, leading to a long relationship of trade and cultural exchange. Cremation sites found in Caracol contain items that would have come from Teotihuacan, showing the relationship between the two distant cities.

"Both central Mexico and the Maya area were clearly aware of each other’s ritual practices, as reflected in the Caracol cremation," said Arlen F. Chase, professor and chair of Comparative Cultural Studies at the University of Houston.

“The connections between the two regions were undertaken by the highest levels of society, suggesting that initial kings at various Maya cities — such as Te K’ab Chaak at Caracol — were engaged in formal diplomatic relationships with Teotihuacan.”

The Chases will present their findings at a conference on Maya–Teotihuacan interaction hosted by the Maya Working Group at the Santa Fe Institute in New Mexico in August 2025.

2 Houston universities declared among world’s best in 2026 rankings

Declaring the Best

Two Houston universities are in a class of their own, earning top spots on a new global ranking of the world's best universities.

Rice University and University of Houston are among the top 1,200 schools included in the QS World University Rankings 2026. Ten more schools across Texas make the list.

QS (Quacquarelli Symonds), a London-based provider of higher education data and analytics, compiles the prestigious list each year; the 2026 edition includes more than 1,500 universities from around the world. Factors used to rank the schools include academic reputation; employer reputation; faculty-student ratio; faculty research; and international research, students, and faculty.

In Texas, University of Texas at Austin lands at No. 1 in the state, No. 20 in the U.S., and No. 68 globally.

Houston's Rice University is close behind as Texas' No. 2 school. It ranks 29th in the U.S. and No. 119 in the world. Unlike UT, which fell two spots globally this year (from No. 66 to 68), Rice climbed up the charts, moving from 141st last year to No. 119.

University of Houston impresses as Texas' 4th highest-ranked school. It lands at No. 80 in the U.S. and No. 556 globally, also climbing about 100 spots up the chart.

Rice and UH are on a roll in regional, national, and international rankings this year.

Rice earned top-15 national rankings by both Niche.com and Forbes last fall. Rice claimed No. 1 and UH ranked No. 8 in Texas in U.S. News & World Report's 2025 rankings. Rice also topped WalletHub's 2025 list of the best colleges and universities in Texas for 2025.

More recently, in April, both UH and Rice made U.S. News' 2025 list of top grad schools.

In all, 192 U.S. universities made the 2026 QS World University Rankings — the most of any country. Topping the global list is the Massachusetts Institute of Technology (MIT).

“The results show that while U.S. higher education remains the global leader, its dominance is increasingly challenged by fast-rising emerging systems,” says the QS World University Rankings report. “A decade ago, 32 American universities [were] featured in the world’s top 100; today, that number has dropped to 26, and only 11 of these institutions have improved their position this year."

The 12 Texas universities that appear in the QS World University Rankings 2026 list are:

University of Texas at Austin, No. 20 in the U.S. and No. 68 in the world (down from No. 66 last year).
Rice University, No. 29 in the U.S. and No. 119 in the world (up from No. 141 last year).
Texas A&M University, No. 32 in the U.S. and No. 144 in the world (up from No. 154 last year).
University of Houston, No. 80 in the U.S. and No. 556 in the world (up from 651-660 last year).
University of Texas at Dallas, No. 85 in the U.S. and No. 597 in the world (down from 596 last year).
Texas Tech University, No. 104 in the U.S. and No. 731-740 in the world (unchanged from last year).
University of North Texas, No. 123 in the U.S. and No. 901-950 in the world (up from 1,001-1,200 last year)
Baylor University, tied for No. 136 in the U.S. and at No. 1,001-1,200 in the world (unchanged from last year).
Southern Methodist University, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
University of Texas Arlington, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
University of Texas at San Antonio, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).

2 Texas cities named on LinkedIn's inaugural 'Cities on the Rise'

jobs data

LinkedIn’s 2025 Cities on the Rise list includes two Texas cities in the top 25—and they aren’t Houston or Dallas.

The Austin metro area came in at No. 18 and the San Antonio metro at No. 23 on the inaugural list that measures U.S. metros where hiring is accelerating, job postings are increasing and talent migration is “reshaping local economies,” according to the company. The report was based on LinkedIn’s exclusive labor market data.

According to the report, Austin, at No. 18, is on the rise due to major corporations relocating to the area. The datacenter boom and investments from tech giants are also major draws to the city, according to LinkedIn. Technology, professional services and manufacturing were listed as the city’s top industries with Apple, Dell and the University of Texas as the top employers.

The average Austin metro income is $80,470, according to the report, with the average home listing at about $806,000.

While many write San Antonio off as a tourist attraction, LinkedIn believes the city is becoming a rising tech and manufacturing hub by drawing “Gen Z job seekers and out-of-state talent.”

USAA, U.S. Air Force and H-E-B are the area’s biggest employers with professional services, health care and government being the top hiring industries. With an average income of $59,480 and an average housing cost of $470,160, San Antonio is a more affordable option than the capital city.

The No. 1 spot went to Grand Rapids due to its growing technology scene. The top 10 metros on the list include:

No. 1 Grand Rapids, Michigan
No. 2 Boise, Idaho
No. 3 Harrisburg, Pennsylvania
No. 4 Albany, New York
No. 5 Milwaukee, Wisconsin
No. 6 Portland, Maine
No. 7 Myrtle Beach, South Carolina
No. 8 Hartford, Connecticut
No. 9 Nashville, Tennessee
