A University of Houston professor has received a grant from the Texas Department of Transportation (TxDOT) to improve the efficiency and effectiveness of how bridges are inspected in the state.

The $505,286 grant will support the project of Vedhus Hoskere, assistant professor in the Civil and Environmental Engineering Department, over three years. The project, “Development of Digital Twins for Texas Bridges,” will look at how to use drones, cameras, sensors and AI to support Texas' bridge maintenance programs.

“To put this data in context, we create a 3D digital representation of these bridges, called digital twins,” Hoskere said in a statement. “Then, we use artificial intelligence methods to help us find and quantify problems to be concerned about. We’re particularly interested in any structural problems that we can identify - these digital twins help us monitor changes over time and keep a close eye on the bridge. The digital twins can be tremendously useful for the planning and management of our aging bridge infrastructure so that limited taxpayer resources are properly utilized.”

The project began in September and will continue through August 2026. Hoskere is joined on the project by Craig Glennie, the Hugh Roy and Lillie Cranz Cullen Distinguished Chair at Cullen College and director of the National Center for Airborne Laser Mapping, as the project’s co-principal investigator.

According to Hoskere, the project will have implications for Texas's 55,000 bridges (more than twice as many as any other state in the country), which need to be inspected every two years.

Outside of Texas, Hoskere says the project will have international impact on digital twin research. Hoskere chairs a sub-task group of the International Association for Bridge and Structural Engineering (IABSE).

“Our international efforts align closely with this project’s goals and the insights gained globally will enhance our work in Texas while our research at UH contributes to advancing bridge digitization worldwide,” he said. “We have been researching developing digital twins for inspections and management of various infrastructure assets over the past 8 years. This project provides us an opportunity to leverage our expertise to help TxDOT achieve their goals while also advancing the science and practice of better developing these digital twins.”

Last year another UH team earned a $750,000 grant from the National Science Foundation for a practical, Texas-focused project that uses AI. The team was backed by the NSF's Convergence Accelerator for its project to help food-insecure Texans and eliminate inefficiencies within the food charity system.

Self-driving semi trucks are now hauling cargo in and out of Houston

Autopilot

The Interstate 45 freight corridor between Houston and Dallas now serves as a testing ground for self-driving cargo trucks.

Silicon Valley startup Kodiak Robotics Inc. recently began sending its autonomous 18-wheel trucks on trips between Texas' two largest metro areas, co-founder and CEO Don Burnette says. The trucks are carrying paid cargo, but Kodiak won't identify the customer or customers. The company also won't say how many trips the trucks are making each day.

The Texas initiative represents Kodiak's first foray into commercial deliveries. Wired.com notes that pretty much every player in the autonomous truck sector has conducted tests in Texas or is carrying commercial loads in the Lone Star State, which boasts more than 2,300 miles of interstate highways.

For its part, Kodiak aims to make Texas "the home of self-driving trucks."

According to a 2016 report from the Texas Department of Transportation, nearly half of all truck freight in Texas goes through the I-45 corridor's 11 counties. In some spots, trucks make up more than one-fourth of the traffic in the corridor, which runs 276 miles from Galveston to where I-45 intersects with Interstate 20 in Dallas County, the TxDOT report says.

"The importance of the I‐45 freight corridor to the movement of goods extends beyond Texas because much of the freight originating or passing through the corridor is destined to other domestic and international markets," the report says.

For now, Burnette says, two people are aboard each Kodiak truck traveling between Houston and Dallas — a safety driver and a safety engineer.

"Dallas will be our home base for testing and operations for the foreseeable future," Burnette says. "Kodiak plans to continue refining and testing its trucks until the last truck-involved accident happens on public roads."

Kodiak's Dallas office, which opened in March, employs eight people. The company plans to relocate soon to new office space in the Dallas suburb of Lancaster, Burnette says.

At this time, Kodiak doesn't plan to hire any workers in Houston, he says.

From its base in the Dallas area, Kodiak envisions expanding its service to routes throughout Texas, but it's focusing solely on the Houston-to-Dallas route for the time being, Burnette says.

Kodiak picked Texas for its truck tests, in part, because of the "warm welcome" extended by Gov. Greg Abbott, TxDOT, the Texas Department of Public Safety, the Texas A&M Transportation Institute, and other segments of the public sector, he says.

In addition, Burnette says, Kodiak chose Texas "because of its great people, freight-rich economy, reasonable regulatory structure, and robust infrastructure."

In 2017, Texas enacted laws enabling driverless vehicles, including long-haul trucks, to operate on the state's roads.

"Texas is a leader in the testing and implementation of connected and automated vehicles, and Kodiak's willingness to partner with academia and public agencies to ensure safe deployment of new technology will add significant value to our transportation system," Christopher Poe, assistant director of the Texas A&M Transportation Institute, says in a release.

Burnette, co-founder of Otto Trucking LLC, a self-driving truck startup purchased in 2016 by Uber Technologies Inc., and fellow entrepreneur Paz Eshel established Kodiak in 2018 to "redefine" long-haul trucking through self-driving technology.

Kodiak says its autonomous technology is designed to ease pressures facing the trucking industry, including a shortage of drivers and high turnover among drivers, while improving highway safety, fostering business efficiency, reducing traffic congestion, and cutting down on harmful emissions.

"Long-haul trucking is primed for autonomous technology," Kodiak says in a post on Medium. "Highway driving is more structured and predictable than urban driving. This means there are fewer decisions for drivers to make and [it's] a better fit for autonomous vehicles."

"As hard as it is to navigate city streets, autonomous vehicles are much closer to being able to drive on more structured interstate highways, which have no jaywalking pedestrians, no aggressive cyclists, and no runaway pets," Kodiak adds. "That's why we've focused on building technology specifically for long-haul trucks driving on highway routes, often referred to as the 'middle mile.'"

TxDOT asks Houstonians for input on rail projects

All aboard

The Texas Department of Transportation is updating a document called the Texas Rail Plan and is seeking input from the public.

The update is designed to reflect the latest rail project priorities and fulfill eligibility requirements for federal funding. Federal requirements say that states' rail plans must be updated every four years to establish policy, priorities, and implementation strategies for freight and passenger rail in the state.

The Texas Rail Plan includes a list of current and future rail projects, which are also depicted on a map. The plan keeps inventory of all rail lines; analyzes rail service goals and contributions to the economy; catalogs and assesses potential infrastructure projects; and examines finance strategies.

The update project began in summer 2018. Meetings of stakeholders were held, and now there's an opportunity for public input. (Stakeholders include citizens, neighboring states, public agencies, and the private rail industry.)

There'll be another round of meetings in the spring, and then the updated plan will be released in summer 2019.

TxDOT hosted a public meeting on December 11, when it presented the update and asked for public questions and input. After that meeting, they extended their deadline for comments to March 1, 2019.

As for now, the public can review and provide input on the plan via this website which explains the history of the Rail Plan and some of the reasons why an update is being done.

There's a survey and online form to submit public comments until January 8, 2019.

If you feel equipped to answer 10 questions such as, "What could be done in Texas to improve freight rail access, promote economic development, and enhance the state's competitiveness in national markets and the global marketplace?" — then this survey should be right up your alley. (Although it should be noted that the hardest questions are first and they get easier as you go along. Also, it's multiple choice.)

These options provide an opportunity for the public to comment on all rail-related issues in Texas, both freight and passenger, as well as existing and future projects and programs.

Houston lab develops AI tool to improve neurodevelopmental diagnoses

developing news

One of the hardest parts of any medical condition is waiting for answers. Speeding up an accurate diagnosis can be a doctor’s greatest mercy to a family. A team at Baylor College of Medicine has created technology that may do exactly that.

Led by Dr. Ryan S. Dhindsa, assistant professor of pathology and immunology at Baylor and principal investigator at the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital, the scientists have developed an artificial intelligence-based approach that will help doctors to identify genes tied to neurodevelopmental disorders. Their research was recently published the American Journal of Human Genetics.

According to its website, Dhindsa Lab uses “human genomics, human stem cell models, and computational biology to advance precision medicine.” The diagnoses that stem from the new computational tool could include specific types of autism spectrum disorder, epilepsy and developmental delay, disorders that often don’t come with a genetic diagnosis.

“Although researchers have made major strides identifying different genes associated with neurodevelopmental disorders, many patients with these conditions still do not receive a genetic diagnosis, indicating that there are many more genes waiting to be discovered,” Dhindsa said in a news release.

Typically, scientists must sequence the genes of many people with a diagnosis, as well as people not affected by the disorder, to find new genes associated with a particular disease or disorder. That takes time, money, and a little bit of luck. AI minimizes the need for all three, explains Dhindsa: “We used AI to find patterns among genes already linked to neurodevelopmental diseases and predict additional genes that might also be involved in these disorders.”

The models, made using patterns expressed at the single-cell level, are augmented with north of 300 additional biological features, including data on how intolerant genes are to mutations, whether they interact with other known disease-associated genes, and their functional roles in different biological pathways.

Dhindsa says that these models have exceptionally high predictive value.

“Top-ranked genes were up to two-fold or six-fold, depending on the mode of inheritance, more enriched for high-confidence neurodevelopmental disorder risk genes compared to genic intolerance metrics alone,” he said in the release. “Additionally, some top-ranking genes were 45 to 500 times more likely to be supported by the literature than lower-ranking genes.”

That means that the models may actually validate genes that haven’t yet been proven to be involved in neurodevelopmental conditions. Gene discovery done with the help of AI could possibly become the new normal for families seeking answers beyond umbrella terms like “autism spectrum disorder.”

“We hope that our models will accelerate gene discovery and patient diagnoses, and future studies will assess this possibility,” Dhindsa added.

Texas robotics co. begins new search for missing Malaysia Airlines flight 370

International News

Malaysia’s government has given final approval for a Texas-based marine robotics company to renew the search for Malaysia Airlines Flight 370, which is believed to have crashed in the southern Indian Ocean more than a decade ago.

Cabinet ministers agreed to terms and conditions for a “no-find, no-fee” contract with Texas-based Ocean Infinity to resume the seabed search operation at a new 5,800-square-mile site in the ocean, Transport Minister Anthony Loke said in a statement Wednesday. Ocean Infinity will be paid $70 million only if wreckage is discovered.

The Boeing 777 plane vanished from radar shortly after taking off on March 8, 2014, carrying 239 people, mostly Chinese nationals, on a flight from Malaysia’s capital, Kuala Lumpur, to Beijing. Satellite data showed the plane turned from its flight path and headed south to the far-southern Indian Ocean, where it is believed to have crashed.

An expensive multinational search failed to turn up any clues to its location, although debris washed ashore on the east African coast and Indian Ocean islands. A private search in 2018 by Ocean Infinity also found nothing.

The final approval for a new search came three months after Malaysia gave the nod in principle to plans for a fresh search.

Ocean Infinity CEO Oliver Punkett earlier this year reportedly said the company had improved its technology since 2018. He has said the firm is working with many experts to analyze data and had narrowed the search area to the most likely site.

Loke said his ministry will ink a contract with Ocean Infinity soon but didn’t provide details on the terms. The firm has reportedly sent a search vessel to the site and indicated that January-April is the best period for the search.

“The government is committed to continuing the search operation and providing closure for the families of the passengers of flight MH370,” he said in a statement.

Harris County booms with 3rd biggest population in U.S.

Boomtown

Newly released U.S. Census Bureau data has revealed Harris County became the third most populous county nationwide in 2024, and it had the highest year-over-year growth rate from 2023.

The new population report, published this month, estimated year-over-year population data from 2023 to 2024 across all 3,144 U.S. counties, and 387 metro areas.

Harris County's numeric growth rate outpaced all other U.S. counties from July 1, 2023 to July 1, 2024, the report found. The Census Bureau estimated Harris County's population grew by 105,852 people year-over-year, bringing the total population to 5,009,302 residents. That's around a 2.16 percent growth rate.

Los Angeles County, California (No. 1) and Illinois' Cook County (No. 2) are the only two U.S. counties that have larger populations than Harris County. Los Angeles County now boasts a population of nearly 9.76 million, while Cook County's has increased to more than 5.18 million people.

The top 10 most populous counties in the U.S. are:

  • No. 1 – Los Angles County, California
  • No. 2 – Cook County, Illinois
  • No. 3 – Harris County, Texas
  • No. 4 – Maricopa County, Arizona
  • No. 5 – San Diego County, California
  • No. 6 – Orange County, California
  • No. 7 – Miami-Dade County, Florida
  • No. 8 – Dallas County, Texas
  • No. 9 – Kings County, New York
  • No. 10 – Riverside County, California

Montgomery County also ranked among the top 10 U.S. counties with the highest numeric growth, ranking 9th nationally after gaining 34,268 residents from 2023 to 2024. Montgomery County's population has now grown to 749,613 people.

In the report's national comparison of counties with the largest population growth by percentage, Montgomery County ranked No. 7 with a year-over-year growth rate of 4.8 percent.

Most populated U.S. metro areas

The U.S. Census Bureau additionally found Houston-Pasadena-The Woodlands nearly led the nation as the second-fastest growing metro area in 2024.

From July 2023 to July 2024, the Houston metro added 198,171 residents to bring the total population to 7,796,182.

New York-Newark-Jersey City was the only metro area to outpace Houston's growth during the one-year period. The New York-New Jersey metro added 213,403 new residents, which brought the total population to over 19.94 million last year.

Kristie Wilder, a Census Bureau Population Division demographer, said in the report that the nation's population growth in its major metros was largely impacted by international migration rather than changes in birth rates.

"While births continue to contribute to overall growth, rising net international migration is offsetting the ongoing net domestic outmigration we see in many of these areas," Wilder said.

Dallas-Fort Worth-Arlington was right behind Houston as the third-fastest growing U.S. metro in 2024. The Metroplex gained 177,922 residents last year, and now has a total population of more than 8.34 million.

The top 10 U.S. metros with the highest numeric growth from 2023 to 2024 are:

  • No. 1 – New York-Newark-Jersey City, New York-New Jersey
  • No. 2 – Houston-Pasadena-The Woodlands, Texas
  • No. 3 – Dallas-Fort Worth-Arlington, Texas
  • No. 4 – Miami-Fort Lauderdale-West Palm Beach, Florida
  • No. 5 – Washington-Arlington-Alexandria, D.C.-Virginia-Maryland-West Virginia
  • No. 6 – Phoenix-Mesa-Chandler, Arizona
  • No. 7 – Orlando-Kissimmee-Sanford, Florida
  • No. 8 – Atlanta-Sandy Springs-Roswell, Georgia
  • No. 9 – Chicago-Naperville-Elgin, Illinois-Indiana
  • No. 10 – Seattle-Tacoma-Bellevue, Washington
