A new breakthrough prototype out of the University of Houston was inspired by science fiction.

"As a big science fiction fan, I could envision a ‘science-fiction-esque future’ where our clothes are smart, interactive and powered,” according to a statement Haleh Ardebili, who last month published a paper on a new stretchable fabric-based lithium-ion battery in the Extreme Mechanics Letters.

“It seemed a natural next step to create and integrate stretchable batteries with stretchable devices and clothing," she said. "Imagine folding or bending or stretching your laptop or phone in your pocket. Or using interactive sensors embedded in our clothes that monitor our health.”

The battery uses conductive silver fabric as a platform and current collector, which stretches (or mechanically deforms) while allowing movement for electrons and ions. Traditional lithium batteries are quite rigid and use a liquid electrolyte, which are flammable and have potential risks of exploding.

The technology is only a prototype now, but Ardebili, who's the Bill D. Cook Professor of Mechanical Engineering at UH, and the paper's first author Bahar Moradi Ghadi, a former doctoral student, think the battery could have many applications, including in smart space suits, consumer electronics and implantable biosensors.

The team's focus now is to ensure the battery is "as safe as possible" before it becomes available on the market.

“Commercial viability depends on many factors such as scaling up the manufacturability of the product, cost and other factors,” Ardebili said. “We are working toward those considerations and goals as we optimize and enhance our stretchable battery.”

Ardebili first conceptualized the product several years ago and has since earned several key wards and grants to support the design, including a five-year National Science Foundation CAREER Award in 2013, a New Investigator Award from the NASA Texas Space Center Grant Consortium in 2014 and an award from the US Army Research Lab in 2017.

A number of Houston-based organizations are working to create innovative batteries.

Earlier this summer, TexPower EV Technologies Inc. opened a 6,000-square-foot laboratory and three-ton-per-year pilot production line in Northwest Houston to help the University of Texas-born company to further commercialize its cobalt-free lithium-ion cathode, which can be used in electric vehicles.

Another Houston-based company Zeta Energy has also developed proprietary sulfur-based cathodes and lithium metal anodes that have shown to have higher capacity and density and better safety profiles than lithium sulfur batteries. The company landed a $4 million grant from the U.S. Department of Energy's ARPA-E Electric Vehicles for American Low-Carbon Living, or EVs4ALL, program, in January.

Houston Nobel Prize nominee earns latest award for public health research

Prized Research

Houston vaccine scientist Dr. Peter Hotez can add one more prize to his shelf.

Hotez — dean of the National School of Tropical Medicine and professor of Pediatrics and Molecular Virology & Microbiology at Baylor College of Medicine, co-director of the Texas Children’s Center for Vaccine Development (CVD) and Texas Children’s Hospital Endowed Chair of Tropical Pediatrics — is no stranger to impressive laurels. In 2022, he was even nominated for a Nobel Peace Prize for his low-cost COVID vaccine.

His first big win of 2025 is this year’s Hill Prize, awarded by the Texas Academy of Medicine, Engineering, Science and Technology (TAMEST).

Hotez and his team were selected to receive $500,000 from Lyda Hill Philanthropies to help fund The Texas Virosphere Project. The endeavor was born to help create a predictive disease atlas relating to climate disasters. Because the climate crisis has ushered in changes to the distribution of diseases, including dengue, chikungunya, Zika, Chagas disease, typhus and tick-borne relapsing fever, it’s important to predict outbreaks before they become a menace.

Rice University researchers are collaborating with Hotez and his team on a project that combines climate science and metagenomics to access 3,000 insect genomes. The goal is to aid health departments in controlling disease and informing policy.

The Hill Prize, which is being awarded to six innovators for the first time, thanks to a $10 million commitment from the philanthropic organization, is intended to back ideas that are high-risk and high-reward. Each of the projects was chosen for its potential real-life impact on some of Texas's — and the world’s — most challenging situations. Hotez’s prize is the first Hill Prize to be given in the realm of public health. The additional winners are:

  • Hill Prize in Medicine: Kenneth M. Hargreaves, D.D.S., Ph.D., The University of Texas Health Science Center at San Antonio
  • Hill Prize in Engineering: Joan Frances Brennecke, Ph.D. (NAE), The University of Texas at Austin
  • Hill Prize in Biological Sciences: David J. Mangelsdorf, Ph.D. (NAM, NAS), UT Southwestern Medical Center
  • Hill Prize in Physical Sciences: James Chelikowsky, Ph.D., The University of Texas at Austin
  • Hill Prize in Technology: Robert De Lorenzo, M.D., EmergenceMed, LLC

How Houston's cost of living compares to other major Texas cities in 2025

Calculating Costs

A new cost-of-living index yields a result that many Houstonians will find surprising: Houston is not the most expensive place to live in Texas. Dallas and Austin are costlier.

Numbeo’s cost-of-living index for 2025 shows Dallas ranks first in Texas and 24th in North America, landing at 65.8. The cost-of-living index compares the cost of living in New York City (which sits at 100) with the cost of living in another city. Austin is at 61.7, Houston at 60.6, and San Antonio at 58.8.

Houston ranks 40th overall in North America, out of 52 cities in the index.

Numbeo’s cost-of-living index takes into account the cost of items like groceries, restaurant meals, transportation, and utilities. The index excludes rent.

When rent is added to the cost-of-living index, Houston is still third among Texas cities. Dallas grabs the No. 21 spot in North America (57.1), one notch above Austin (56.6). Houston ranks 35th (51.4), and San Antonio ranks 42nd (34.6).

Rent index
While Dallas holds the top Texas spot on Numbeo’s overall cost-of-living index, Austin faces the highest rent prices. Numbeo's rent index for Austin sits at 50.1, putting it in 12th place among major cities in North America and highest in Texas, above the indexes for Dallas, Houston, and San Antonio. Houston lands at 27th.

The rent index in New York City, which tops the list, is 100. As Numbeo explains, the rent index estimates the cost of renting an apartment in a city compared with New York City. If the rent index is 50, for example, this suggests the average rent in that city is 50 percent below the average rent in New York City.

Around Texas, the rent index is:

  • 46.2 in Dallas
  • 39.8 in Houston
  • 34.6 in San Antonio

Restaurant index
In contrast to its showing on the rent and cost-of-living indexes, Houston outranks Dallas, Austin, and San Antonio on Numbeo’s restaurant index. This index compares the prices of meals and drinks at restaurants and bars to those in New York City.

Houston sits at No. 25 on the restaurant index, at 68.9. Dallas comes in at No. 32 (67.1), Austin at No. 34 (66.6), and San Antonio at No. 36 (65.2).

The National Restaurant Association reported in December that menu prices in the U.S. had risen 3.6 percent in the past 12 months, outpacing gains in grocery prices and the federal government’s overall Consumer Price Index. Fortunately for diners, that was the smallest 12-month increase in menu prices since August 2020, according to the association.

Toast, which provides a cloud-based restaurant management system, says the higher menu prices reflect higher food prices.

“Food prices have been increasing due to inflation, labor expenses, fuel costs, and supply chain disruptions, all of which impact restaurant profitability, Toast says. “While raising menu prices is one option to combat rising food costs, some restaurants have introduced service charges and simplified menus to avoid passing all costs onto customers.”

Houston startup taps strategic partner to produce novel 'biobased leather'

cleaner products

A Houston-based next-gen material startup has revealed a new strategic partnership.

Rheom Materials, formerly known as Bucha Bio, has announced a strategic partnership with thermoplastic extrusion and lamination company Bixby International, which is part of Rheom Material’s goal for commercial-scale production of its novel biobased material, Shorai.

Shorai is a biobased leather alternative that meets criteria for many companies wanting to incorporate sustainable materials. Shorai performs like traditional leather, but offers scalable production at a competitive price point. Extruded as a continuous sheet and having more than 92 percent biobased content, Shorai achieves an 80 percent reduction in carbon footprint compared to synthetic leather, according to Rheom.

Rheom, which is backed by Houston-based New Climate Ventures, will be allowing Bixby International to take a minority ownership stake in Rheom Materials as part of the deal.

“Partnering with Bixby International enables us to harness their extensive expertise in the extrusion industry and its entire supply chain, facilitating the successful scale-up of Shorai production,” Carolina Amin Ferril, CTO at Rheom Materials, says in a news release. “Their highly competitive and adaptable capabilities will allow us to offer more solutions and exceed our customers’ expectations.”

In late 2024, Rheom Materials started its first pilot-scale trial at the Bixby International facilities with the goal of producing Shorai for prototype samples.

"The scope of what we were doing — both on what raw materials we were using and what we were creating just kept expanding and growing," founder Zimri Hinshaw previously told InnovationMap.
