Waymo has suspended driverless car services in Houston and other major Texas cities, and in Atlanta, after one of its vehicles was stranded by flooding during heavy rains that will likely also hinder travel in a large swath of the U.S over the holiday weekend.

Severe thunderstorms with large hail and gusty winds were possible Friday, May 22 in Texas and other parts of the Southern and Central Plains, the National Weather Service said.

Forecasters warned of possible flash flooding along the Gulf Coast of Texas and Louisiana on Saturday, when rain and thunderstorms were expected across much of the central and eastern U.S.

The Waymo vehicle got stuck during a downpour in Atlanta on Wednesday that flooded streets and even part of a downtown highway. The vehicle was not occupied and was later recovered, the company said in a statement. At least one other Waymo vehicle was waylaid during the storm.

Waymo serves only the city of Atlanta in Georgia, and services Dallas, Houston, Austin, and San Antonio in Texas.

The company paused service in Texas “out of an abundance of caution for the forecasted severe weather,” the statement said.

Self-driving rideshare company cruises its robotaxies into Houston

look ma, no driver

Anew driverless ridehail service is coming to Houston: Cruise, the all-electric, driverless car company backed by GM, is expanding in Texas with launches in both Dallas and the Bayou City.

This follows an initial launch in Austin in 2022, their first city in Texas.

Cruise builds and operates driverless vehicles that you can call via an app, like any other ride hailing service. "But our vehicles show up without anyone else inside," they say.

The entire fleet is all-electric and the vehicles are equipped with a 360-view, with the ability to react to whatever they encounter on the road.

They test their vehicles using simulations, through millions of scenarios and virtual miles; they’ve also driven more than 4 million real miles, mostly in San Francisco.

They have not defined what the cost will be but according to The Verge, the rates in San Francisco vary depending on length of trip and time of day: "A customer taking a 1.3-mile trip would pay 90 cents per mile and 40 cents per minute, in addition to a $5 base fee and 1.5 percent city tax, for a total of $8.72." By comparison, an Uber ride for the same trip would cost at least $10.41.

The company was founded in 2013 and vehicles began to hit the road in 2022. They operate a total fleet of roughly 300 all-electric AVs, powered 100 percent by renewable energy. In addition to Austin, they operate in San Francisco and Phoenix, where they've completed 35,000 self-driving deliveries in a partnership with Walmart.

According to a statement from CEO Kyle Vogt, they'll begin supervised driving (with a safety driver behind the wheel) in Houston as they finetune their AI technology to understand the nuances and unique elements of the city, with Dallas to follow shortly after.

In a blog post, Vogt says their cars drive the speed limit and come to a complete stop at every stop sign. They respond to police sirens, flashing lights on fire trucks or ambulances, and stop signs that fold out of school buses.

They react to people on scooters, people using bike lanes, and cars driving on the wrong side of the road. "In short, they are designed to drive safely by obeying the law and driving in a humanlike way," he says. Actually, that sounds better than humans.

When vehicles encounter a situation where they aren’t 100 percent sure of what to do, they slow down or stop and pull over to the side of the road. This has caused some bumps in San Francisco where cars stopped and idled in the street for no apparent reason, delaying bus riders and disrupting the work of firefighters.

Some of the "bumps" have been comical, such as the 2022 incident in which a confused San Francisco police officer pulled a Cruise over, and then the Cruise drove away.

And as Reuters notes, autonomous vehicles have not rolled out as fast as anticipated, due to regulations, safety investigations, and arduous technology.

When Cruise first enters a city, they hire a mapping and data collection team to learn bike lanes, school zones, and major intersections. But most of the time, the vehicles will be carrying riders in the back seat, or completely empty and en route to another pickup.

The company partners with first responders, including police and fire departments, to ensure they’re ready and familiar with how to interact with the vehicles, engaging with those agencies before and after launch.

"Our guiding mission has always been to improve road safety, reduce emissions, and reduce congestion with our driverless ride-hail service in cities, which is where we’ll see the most significant positive impact the soonest," Vogt says. "Houston and Dallas are committed to reducing traffic deaths as part of their Vision Zero commitments, and we are excited to operate in and partner with these new communities in this shared mission."

Houston researchers report promising first in-human trial for implantable cancer therapy

cancer breakthrough

When it comes to cancer remedies, the treatment can be as challenging for the body as its cause. But what if immunotherapy could be localized? That’s precisely what a Houston team may soon make a reality.

Rice University researchers, in partnership with MD Anderson Cancer Center, recently published their findings from the first in-human trial of an implantable cancer-fighting treatment in the journal Clinical Cancer Research. The paper details testing of AVB-001, encapsulated cells engineered to release interleukin-2 (IL-2)—a naturally occurring signaling protein that boosts immunity—in the peritoneal cavities of 14 patients. The goal is to avoid the toxicity usually experienced with less targeted treatments, as well as find a solution to IL-2s’ abbreviated half-lives.

“Traditional IL-2 therapy has shown potent antitumor activity, but its clinical use has been limited by severe side effects and delivery challenges,” Omid Veiseh, director of the Rice Biotech Launch Pad, professor of bioengineering at Rice and a senior author on the study, said in a press release. “This platform allows us to localize and sustain cytokine exposure directly where tumors reside while minimizing systemic toxicity.”

Serous ovarian carcinoma is especially well-suited to the use of AVB-001 because it tends to spread throughout the abdomen. After a minimally invasive laparoscopic procedure, patients implanted with the cells were noted to tolerate the treatment well. Half of the enrolled patients’ cancer was stabilized, with several among them reporting extended signs of benefit. No maximum tolerated dose was reached and there were no life-threatening events tied to the study.

If that sounds like less-than-earth-shaking results, this is only the beginning. The capsules were implanted for about one week because IL-2 activity drops off after that. The researchers now know that further testing should include either higher levels, repeated doses, or a combination thereof, in order to create stronger advances.

The team has already made early headway on this next step. Preclinical studies in nonhuman primates were not only tolerated well, but without added toxicity, the apes had consistent pharmacological effects.

“This is a foundational step,” Veiseh explained. “We now have evidence that the platform is safe, biologically active and potentially scalable. The next phase is optimizing dosing and exploring combination therapies to unlock its full clinical potential.”

The combination would also include a checkpoint inhibitor, which might improve AVB-001’s tumor-fighting power. “What is exciting is that we are not just delivering a drug, we are programming a microenvironment,” added Dr. Amir Jazaeri, professor of gynecologic oncology at MD Anderson, member of the Rice Biotech Launch Pad’s clinical advisory board and a senior author on the study. “This opens the door to combination strategies that could amplify immune responses in ways that have not been feasible before.”
