According to a report, Houston traffic is actually the worst. Local.AllState.com

Honk if you hate Houston traffic. According to a new study, you’re more than justified in laying on the horn to express frustration over Houston’s clogged roads.

The study, released by geolocation technology company TomTom, shows the typical Houston driver wasted 46 hours last year due to traffic congestion. Houston’s traffic congestion rate was 20 percent. This means average travel times in jammed-up traffic were 20 percent longer than they were in uncongested traffic.

While those figures alone highlight the drive-me-up-a-wall status of Houston commutes, what’s worse is that the city ranks first in Texas, No. 16 in the U.S., and No. 214 in the world for snarled traffic in 2021. The study says Houston’s traffic congestion went up 4 percent compared with 2020 but went down 4 percent compared with pre-pandemic 2019.

Where’s the worst of the worst traffic in Houston? According to Texas A&M Transportation Institute data published in December, the 610 West Loop was the state’s most congested stretch of roadway in 2020, trading places with I-35 in Austin, which held the top spot in 2019.

On top of that, Houston is home to 10 of the 14 worst trucking bottlenecks in Texas, according to an American Transportation Research Institute ranking released earlier this month. The absolute worst: I-45 at I-69 and U.S. Highway 59. The institute deemed that intersection the third worst trucking bottleneck in the country for 2021.

“Bottlenecks around the state continue to waste time and money, further damaging the already fragile supply chain,” John Esparza, president and CEO of the Texas Trucking Association, says in a news release. “With the newly available federal resources for infrastructure projects, there’s no excuse — these bottlenecks must be addressed. A reliable and stable transportation network is essential to our economy — just like the trucking industry.”

Here’s how other major Texas cities fared in the TomTom study:

  • McAllen ranked second in Texas, 18th in the U.S., and 218th in the world for traffic congestion. Time wasted in traffic last year for a typical driver: 46 hours. Congestion rate: 20 percent. Congestion up 4 percent from 2020 and up 1 percent from 2019.
  • Austin ranked third in Texas, 21st in the U.S., and 221st in the world for traffic congestion. Time wasted in traffic last year for a typical driver: 46 hours. Congestion rate: 20 percent. Congestion up 2 percent from 2020 and down 7 percent from 2019.
  • Dallas-Fort Worth ranked fourth in Texas, 37th in the U.S., and 305th in the world for traffic congestion. Time wasted in traffic last year for a typical driver: 39 hours. Congestion rate: 17 percent. Congestion up 4 percent from 2020 but down 2 percent from 2019.=
  • San Antonio ranked fifth in Texas, 41st in the U.S., and 318th in the world for traffic congestion. Time wasted in traffic last year for a typical driver: 36 hours. Congestion rate: 16 percent. Congestion up 3 percent from 2020 and down 3 percent from 2019.
  • El Paso ranked sixth in Texas, 44th in the U.S., and 324th in the world for traffic congestion. Time wasted in traffic last year for a typical driver: 36 hours. Congestion rate: 16 percent. Congestion up 4 percent from 2020 and the same as 2019.

Not surprisingly, the TomTom study awards New York City the title of the worst-congested place in the country. In 2021, the typical New York driver wasted 80 hours in traffic, with a 35 percent congestion rate.

Racking up a congestion rate of 62 percent last year, Istanbul, Turkey, claimed the title of the world’s worst city for traffic. There, motorists wasted 142 hours in traffic in 2021.

UH, Baylor researchers make breakthrough with new pediatric leukemia treatment device

childhood cancer

A team of Houston researchers has developed a new microfluidic device aimed at making treatments safer for children with hyperleukocytosis, a life-threatening hematologic emergency often seen in patients with leukemia.

Dr. Fong Lam, an associate professor of pediatrics at Baylor College of Medicine and a pediatric intensive care physician at Texas Children’s Hospital, partnered with Sergey Shevkoplyas, a professor of biomedical engineering at UH, on the device that uses a large number of tiny channels to quickly separate blood cells by size in a process called controlled incremental filtration, according to a news release from UH.

They tested whether performing cell separation with a high-throughput microfluidic device could alleviate the limitations of traditional conventional blood-filtering machines, which pose risks for pediatric patients due to their large extracorporeal volume (ECV), high flow rates and tendency to cause significant platelet loss in the patient. The results of their study, led by Mubasher Iqbal, a Ph.D. candidate in biomedical engineering at UH, were published recently in the journal Nature Communications.

“Continuously and efficiently separating leukocytes from recirculating undiluted whole blood — without device clogging and cell activation or damage — has long been a major challenge in microfluidic cell separation,” Shevkoplyas said in a news release. “Our study is the first to solve this problem.”

Hyperleukocytosis is a condition that develops when the body has an extremely high number of white blood cells, which in many cases is due to leukemia. According to the release, up to 20 percent to 30 percent of patients with acute leukemia develop hyperleukocytosis, and this places them at risk for potentially fatal complications.

The new device utilizes tiny channels—each about the width of a human hair—to efficiently separate blood cells through controlled incremental filtration. According to Lam, the team was excited that the new device could operate at clinically relevant flow rates.

The device successfully removed approximately 85 percent of large leukocytes and 90 percent of leukemic blasts from undiluted human whole blood without causing platelet loss or other adverse effects. It also operates with an ECV that’s about 1/70th of conventional leukapheresis machines, which makes it particularly suitable for infants and small children.

“Overall, our study suggests that microfluidics leukapheresis is safe and effective at selectively removing leukocytes from circulation, with separation performance sufficiently high to ultimately enable safe leukapheresis in children,” Shevkoplyas said in the release.

Greentown Labs adds 5 new Houston startups to climatetech incubator

Going Green

Greentown Labs announced that it added five startups to its Houston community in Q1 of 2025.

The companies are among a group of 19 that joined the climatetech incubator, which is co-located in Houston and Boston, in the same time period. The companies that joined the Houston-based lab specialize in a number of "green" applications, from converting plastic waste into sustainable materials to developing energy-storage solutions.

The new Houston members include:

  • Concept Loop, a project of Pakistan-based Innova8e Inc., aims to repurpose post-industrial and post-consumer plastic waste into sustainable building materials.
  • GeoFuels, a Sugar Land-based company that produces hydrogen by using baseload geothermal power and methane pyrolysis.
  • PLASENE, a Houston-based company with an innovative platform that converts plastic waste into liquid fuel and low-carbon hydrogen through its proprietary catalysts and modular, scalable, pre-engineered units platform. The company was named to Greentown's ACCEL Year 3 cohort earlier this year.
  • RepAir Carbon, an Israeli company with a fully electric, zero-heat carbon-removal technology that consumes minimal energy, operates without liquids or solvents, and produces no hazardous materials or waste.
  • RotorVault from Pasadena, California, is commercializing energy-storage and load-following solutions that are containerized, modular, and field-deployable systems built on flywheel technology.

Fourteen other companies will join Greentown Boston's incubator. See the full list here.

PLASENE and five other new members—Thola, Respire Energy, Andros Innovations, FAST Metals and Tato Labs—join Greentown Labs through its most recent Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, cohort. ACCEL, which works to advance BIPOC-led startups in the climatetech space, announced its third cohort last month.

Houston startup unveils its innovative leather alternative at the rodeo

sustainable fashion

Last month’s Houston Livestock Show and Rodeo stirred up another rootin’ tootin’ time for Houstonians and beyond.

But before the annual event galloped into the sunset, there were quite a few memorable innovations on display, with one notably coming from Rheom Materials.

The Houston-based pioneer of next-generation materials presented its scalable, bio-based alternative known as Shorai, a 93 percent bio-based leather, through two custom, western-inspired outfits that showed off cowboy flair through a sustainable lens.

“I'm a Houstonian, I love the rodeo,” Megan Beck, Rheom’s business development manager, recalls. “We're sitting there talking about it one day and we're like, ‘Okay, we've got to do something with this leather to show people how good it can look in apparel, how easy it is to wear.’”

Buoyed by the idea that their materials are meant to “change your impact, not your life,” Rheom captured the real-life energy of their bio-leather outfits under the rodeo’s neon lights in a short commercial video and photo shoot with models donning the samples, while dancing and enjoying the festivities. Rheom created a skirt, a leather jacket, and then a leather top for the look.

“Houston is such a vibrant city,” Beck says. “There's so much innovation here. I think the rodeo is just a really, really great example of that. And so we wanted to take this opportunity to take some of these garments out there and go on the slide, go on some of the rides, go into the wine garden and go dancing, because if you've ever felt some of the materials in the market in this space, they're very stiff, you can't really move in them, they're a little fragile, they kind of fall apart.”

Not only do the models in the video look fashionable, but they also look comfortable, and the leather looks natural and supple. And to the naked eye, Shorai appears to be like the leather most wearers are accustomed to.

“What we really wanted to showcase in this is the energy and the movement of the leather, and to show people how good it can look in apparel, and how easy it is to wear, which I think we were able to accomplish,” Beck says.

Next up, Beck says Rheom wants to scale production of Shorai, the Japanese word for “future,” at a competitive price point, while also reducing its carbon footprint by 80 percent when compared to synthetic leather. According to Beck, Rheom plans to see Shorai products come to market sometime this year.

“We have companies globally right now that are testing materials, that are prototyping, that are making garments, making handbags and footwear, and making eyewear because we have a plastic, as well,” Beck says. “So, this year, I do believe we'll start seeing those products actually come to market, which is very, very exciting for us.”

And with their large-scale production partner already set up for Shorai, Rheom plans to start its first production run of the product soon.

“In April, we'll actually be starting our first production run,” Beck says. “We'll be doing it at full scale, full width, and a full run of materials. So over the next five years, we're only going to just try to increase that capacity.”
