A California-based tech company has got the green light today to move forward a new line of autonomous vehicles that will soon hit Houston streets.

Nuro, which has a few self-driving delivery pilot programs across Houston, has been granted its exemption petition from the United States Department of Transportation's National Highway Traffic Safety Administration. This move is a first for DOT, and it allows Nuro to roll out its vehicles on public roads without the features of traditional, passenger-carrying vehicles — like side mirrors or windshields, for instance.

"Since this is a low-speed self-driving delivery vehicle, certain features that the Department traditionally required – such as mirrors and windshield for vehicles carrying drivers – no longer make sense," says U.S. Secretary of Transportation Elaine L. Chao in a news release.

Now, with this permission, Nuro has unveiled its newest model — the R2. The new model is more narrow than the R1, and has 65 percent more climate-controlled space for its food deliveries. The vehicle also has new safety features, like 360-degree vision using lidar, radar, and cameras and even has a pedestrian-protecting feature that enables the car to collapse on impact.

"We founded Nuro on the belief that we could reimagine, design, and develop an autonomous vehicle that would make the world a safer place," says Nuro co-founder and president, Dave Ferguson, in a release. "Our second-generation vehicle will advance our goal of transforming local commerce, and we are gratified that the Department of Transportation, under Secretary Chao's leadership, is promoting public safety and providing regulatory certainty for the self-driving industry."

The R2 models are being assembled in the U.S. with Nuro's partner, Roush Enterprises, which is based in Michigan. Per the NHTSA announcement, Nuro can deploy up to 5,000 R2 vehicles during the two-year exemption period. According to the DOT release, the organization will be monitoring Nuro's work throughout those two years.

"NHTSA is dedicated to facilitating the safe testing and deployment of advanced vehicle technologies, including innovative vehicle designs, which hold great promise for future safety improvements," says NHTSA Acting Administrator James Owens in the release. "As always, we will not hesitate to use defect authority to protect public safety as necessary."

Nuro currently has three pilot programs — all of which were announced last year. The company is working with Domino's, Kroger, and Walmart on food and grocery deliveries in six Houston ZIP codes. Since entering the Houston market, Nuro has been using its fleet of self-driving Prius vehicles to research and map the city's roads.

With this permission granted from DOT, Nuro can start making deliveries using its R2 fleet with its three retail and restaurant partners.

"Today's decision shows that 'exemption' can mean more safety," says Ferguson. "Our world-class team solved countless novel problems to create this design, and, after extensive modeling, research, and testing, created a vehicle unlike any other on the road today."

Kroger's autonomous car fleet heads to Houston for a new grocery delivery service

Look ma, no hands

Hold on to your hats, Houston. Autonomous cars are hitting the streets this spring as Kroger rolls out its fleet of self-driving, grocery-delivery cars.

Two Houston Kroger locations will provide the service to four ZIP codes — 10306 South Post Oak Road, servicing 77401 and 77096, and 5150 Buffalo Speedway, servicing 77005 and 77025.

Kroger, along with California-based robotics company, Nuro, has been operating self-driving cars delivering groceries in Scottsdale. Arizona since August. According to the release, the service has delivered thousands of orders in the self-driving vehicles.

"We've seen first-hand in Arizona how enthusiastic customers are about getting their Kroger groceries delivered by a Nuro self-driving vehicle," says Nuro co-founder, Dave Ferguson, in a release. "Texas has been a leader in encouraging self-driving innovation, and we're excited to help deliver that future for Houston — a dynamic, diverse, and welcoming metropolitan city that we're excited to soon explore and serve with this autonomous delivery service."

The service costs a flat fee of $5.95, and users can order in the app or online for same-day or next-day delivery, seven days a week. The program will launch using Toyota Prius vehicles. Currently, the exact start date of the service hasn't been provided.

"Our Arizona pilot program confirmed the flexibility and benefits provided by autonomous vehicles and how much customers are open to more innovative solutions," says Yael Cosset, Kroger's chief digital officer, in a release. "It's always been our shared vision to scale this initiative to new markets, using world-changing technology to enable a new type of delivery service for our customers. We operate 102 stores in Houston—an energetic market that embraces digital and technology advancement. The launch is one more way we are committed to sustainably providing our customers with anything, anytime, and anywhere, the way they want it."

In January, the Texas Department of Transportation created the Connected and Autonomous Vehicle Task Force to focus on being a comprehensive resource for information on all Texas CAV projects, investments, and initiatives.

"With our world-class universities, top-notch workforce and startup culture, Texas is a national leader in the development of new technologies," says Gov. Greg Abbott in the release. "As transportation technology advances, the CAV Task Force will ensure that the Lone Star State remains at the forefront of innovation."

Houston medtech startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization

Texas still ranks as No. 1 in U.S. for inbound moves, but growth dips

by the numbers

Texas continues to be the country’s No. 1 magnet for newcomers from other states, giving a boost to the state’s economy. However, Texas’ appeal weakened in 2024 compared with the previous year, due in large part to spiking home prices.

An analysis of U.S. Census Bureau data by self-storage platform StorageCafe shows Texas saw net interstate migration of 76,000 people in 2024. Texas’ net interstate migration dropped nearly 50 percent from 2023, according to the analysis. Net migration refers to the number of incoming residents minus the number of outgoing residents.

California remained the top source of newcomers for Texas, sending nearly 77,000 residents to the Lone Star State in 2024, the analysis says. Florida ranked second, followed by New York, Colorado and Illinois.

“These trends reveal Texas’ continued pull from both high-cost coastal markets and other large Sun Belt states, resulting in a mix of affordability-driven and job-driven relocation,” StorageCafe says.

Putting a damper on the influx of new residents: a roughly 124 percent surge in Texas home prices over the past decade, according to StorageCafe.

“While the state remains significantly more affordable than California, its top feeder state, the once-wide pricing gap has narrowed,” says StorageCafe. “For many movers, Texas is still a relative bargain, but no longer an undisputed one.”

Nonetheless, Texas keeps attracting young, highly educated people, which bodes well for the state’s long-term economic outlook, StorageCafe says. More than half of new arrivals to Texas in 2024 held at least a bachelor’s degree, and the age of newcomers averaged 32.

Where are most of these young, highly educated newcomers settling?

Lloyd Potter, former Texas state demographer, tells StorageCafe that population growth in Texas is happening most rapidly in suburban “ring counties” at the expense of slowing growth in urban cores. Ring counties are on the outskirts of major metro areas.

“Many people are moving from urban cores to suburban rings seeking lower costs, newer housing, better schools, and more space,” Potter says. “Typically, a move to a suburban county will be within commuting or hybrid‑commuting distance of major metro economies.”

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”
