Houston is a car dependent city and Houstonians spend approximately 75 hours a year in traffic. Ridesharing is a safer and more comfortable way to connect people and the places they need to travel. As Houston continues to grow — the city added 250 people a day in the last year — transportation options are crucial to connect people to the places they need to go.

What’s an alternative to driving your own vehicle? Ridesharing.

Ridesharing has many benefits, and it’s crucial that rideshare models both deliver a safe and consistent experience to passengers while supporting the needs of the cities in which they operate. In my view, responsible ridesharing has three parts: safety, fleet optimization, and sustainability.

The most obvious benefit is safety. The most important objective rideshare businesses have is to transport passengers from point A to point B; everyone in the vehicle is precious cargo. If you’re out drinking, for example, you can ditch your personal vehicle and call for a ride. Having drivers that are professionally trained and their mission to make sure you arrive at your destination safely is the most important priority.

I founded Alto with the mission to create a safer rideshare experience for passengers and drivers alike. To me, personal safety while riding or driving should be the top priority of a ridesharing company. Safety is at the core of Alto’s business model, and it’s built into everything we do. At the center of our business is our W-2 employee drivers who are background checked and complete a driver safety training program. Other features include in-car surveillance, telematic tracking, and in-app tracking of your Alto’s position and status. These features are key in creating a safer way to travel as well as building rapport with customers.

Responsible rideshare services also need to have purposeful wait times. Calling for an on-demand ride and receiving a two-minute pick up time is not sustainable and not good for cities. It doesn’t make sense for your ride to arrive faster than an ambulance would. Having such short wait times incentivizes putting more cars on the road and increases the number of drivers driving around a small section of the city waiting for the next ride request. More cars on the road lead to road congestion and even slowing down road lanes that are dedicated to public transit. Even extending a wait time for pick up to 10-15 minutes can greatly reduce the number of vehicles needed to serve customers, alter customers’ approach to hailing a ride, and with a little planning, create greater efficiencies for the city, customers, and the business.

Rideshare fleets that have sustainable assets are essential for acting as a responsible industry in cities and demonstrates a business’s positive impact. For many years we’ve been hearing about the great electric vehicle (EV) revolution for personal vehicles. But what about rideshare fleets? I think ridesharing services will continue to grow as a transportation alternative and I believe that the rideshare industry should prioritize electrification.

It’s not enough to put vehicles on the road without trying to make the industry more sustainable and climate conscious. Houston, an energy sector powerhouse, is leading the green energy transition and I think Houstonians, along with riders all over the country, want to see EV rideshare fleets.

My company Alto, for example, has announced its vision to transition our entire fleet to EVs over the next two years. There are few discussions about the EV transition for fleets and I’m proud that Alto is leading the industry in this regard. This EV vision is one example of how a rideshare company can build a better and more accountable industry, and these steps also give Houstonians a more responsible and sustainable transportation solution.

As Houston continues to grow, Houstonians will need transportation alternatives that meet various trip demands and do not overwhelm or harm the city’s transportation capabilities. Safety protocols, optimized fleets, and sustainability are all essential factors needed in a transportation framework to keep up with Houston’s economic and population growth. To get to that dinner reservation, the game at the Toyota Center, or that conference at the Convention Center, Houstonians should have access to a transportation alternative — ridesharing — to get them to their destination responsibly, safely, and sustainably.

Houston suburb ranks as No. 3 best place to retire in Texas

Rankings & Reports

Texas retirees on the hunt for the right place to settle down and enjoy their blissful retirement years will find their haven in the Houston suburb of Pasadena, which just ranked as the third-best city to retire statewide.

A new study conducted by the research team at RetirementLiving.com, "The Best Cities to Retire in Texas," compared the affordability, safety, livability, and healthcare access for seniors across 31 Texas cities with at least 90,000 residents.

Wichita Falls, about 140 miles northwest of Dallas, claimed the top spot as the No. 1 best place to retire in Texas.

The senior living experts said Pasadena has the best healthcare access for seniors in the entire state, and it ranked as the No. 8 most affordable city on the list.

"Taking care of one’s health can be stressful for seniors," the report said. "Harris County, where [Pasadena is] located, has 281.1 primary care physicians per 1,000 seniors — that’s almost 50-fold the statewide ratio of 5.9 per 1,000."

Pasadena ranked 10th overall for its livability, and ranked 25th for safety, the report added.

Meanwhile, Houston proper ranked as the No. 31 best place to retire in Texas, but its livability score was the 7th best statewide.

Seven of the Lone Star State's top 10 best retirement locales are located in the Dallas-Fort Worth Metroplex: Carrollton (No. 2), Plano (No. 4), Garland (No. 5), Richardson (No. 6), Arlington (No. 7), Grand Prairie (No. 8), and Irving (No. 9). McAllen, a South Texas border town, rounded out the top 10.

RetirementLiving said Carrollton has one of the lowest property and violent crime rates per capita in Texas, and it ranked as the No. 5 safest city on the list. About 17 percent of the city's population is aged 65 or older, which is higher than the statewide average of just 14 percent.

The top 10 best place to retire in Texas in 2026 are:

  • No. 1 – Wichita Falls
  • No. 2 – Carrollton
  • No. 3 – Pasadena
  • No. 4 – Plano
  • No. 5 – Garland
  • No. 6 – Richardson
  • No. 7 – Arlington
  • No. 8 – Grand Prairie
  • No. 9 – Irving
  • No. 10 – McAllen

Rice University lands $18M to revolutionize lymphatic disease detection

fresh funding

An arm of the U.S. Department of Health and Human Services has awarded $18 million to scientists at Rice University for research that has the potential to revolutionize how lymphatic diseases are detected and help increase survivability.

The lymphatic system is the network of vessels all over the body that help eliminate waste, absorb fat and maintain fluid balance. Diseases in this system are often difficult to detect early due to the small size of the vessels and the invasiveness of biopsy testing. Though survival rates of lymph disease have skyrocketed in the United States over the last five years, it still claims around 200,000 people in the country annually.

Early detection of complex lymphatic anomalies (CLAs) and lymphedema is essential in increasing successful treatment rates. That’s where Rice University’s SynthX Center, directed by Han Xiao and Lei Li, an assistant professor of electrical and computer engineering, comes in.

Aided by researchers from Texas Children’s Hospital, Baylor College of Medicine, the University of Texas at Dallas and the University of Texas Southwestern Medical Center, the center is pioneering two technologies: the Visual Imaging System for Tracing and Analyzing Lymphatics with Photoacoustics (VISTA-LYMPH) and Digital Plasmonic Nanobubble Detection for Protein (DIAMOND-P).

Simply put, VISTA-LYMPH uses photoacoustic tomography (PAT), a combination of light and sound, to more accurately map the tiny vessels of the lymphatic system. The process is more effective than diagnostic tools that use only light or sound, independent of one another. The research award is through the Advanced Research Projects Agency for Health (ARPA-H) Lymphatic Imaging, Genomics and pHenotyping Technologies (LIGHT) program, part of the U.S. HHS, which saw the potential of VISTA-LYMPH in animal tests that produced finely detailed diagnostic maps.

“Thanks to ARPA-H’s award, we will build the most advanced PAT system to image the body’s lymphatic network with unprecedented resolution and speed, enabling earlier and more accurate diagnosis,” Li said in a news release.

Meanwhile, DIAMOND-P could replace the older, less exact immunoassay. It uses laser-heated vapors of plasmonic nanoparticles to detect viruses without having to separate or amplify, and at room temperature, greatly simplifying the process. This is an important part of greater diagnosis because even with VISTA-LYMPH’s greater imaging accuracy, many lymphatic diseases still do not appear. Detecting biological markers is still necessary.

According to Rice, the efforts will help address lymphatic disorders, including Gorham-Stout disease, kaposiform lymphangiomatosis and generalized lymphatic anomaly. They also could help manage conditions associated with lymphatic dysfunction, including cancer metastasis, cardiovascular disease and neurodegeneration.

“By validating VISTA-LYMPH and DIAMOND-P in both preclinical and clinical settings, the team aims to establish a comprehensive diagnostic pipeline for lymphatic diseases and potentially beyond,” Xiao added in the release.

The ARPA-H award funds the project for up to five years.
