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 team’s discovery brings solid-state batteries closer to EV use

A Better Battery

A team of researchers from the University of Houston, Rice University and Brown University has uncovered new findings that could extend battery life and potentially change the electric vehicle landscape.

The team, led by Yan Yao, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering at UH, recently published its findings in the journal Nature Communications.

The work deployed a powerful, high-resolution imaging technique known as operando scanning electron microscopy to better understand why solid-state batteries break down and what could be done to slow the process.

“This research solves a long-standing mystery about why solid-state batteries sometimes fail,” Yao, corresponding author of the study, said in a news release. “This discovery allows solid-state batteries to operate under lower pressure, which can reduce the need for bulky external casing and improve overall safety.”

A solid-state battery replaces liquid electrolytes found in conventional lithium-ion cells with a solid separator, according to Car and Driver. They also boast faster recharging capabilities, better safety and higher energy density.

However, when it comes to EVs, solid-state batteries are not ideal since they require high external stack pressure to stay intact while operating.

Yao’s team learned that tiny empty spaces, or voids, form within the solid-state batteries and merge into a large gap, which causes them to fail. The team found that adding small amounts of alloying elements, like magnesium, can help close the voids and help the battery continue to function. The team captured it in real-time with high-resolution videos that showed what happens inside a battery while it’s working under a scanning electron microscope.

“By carefully adjusting the battery’s chemistry, we can significantly lower the pressure needed to keep it stable,” Lihong Zhao, the first author of this work, a former postdoctoral researcher in Yao’s lab and now an assistant professor of electrical and computer engineering at UH, said in the release. “This breakthrough brings solid-state batteries much closer to being ready for real-world EV applications.”

The team says it plans to build on the alloy concept and explore other metals that could improve battery performance in the future.

“It’s about making future energy storage more reliable for everyone,” Zhao added.

The research was supported by the U.S. Department of Energy’s Battery 500 Consortium under the Vehicle Technologies Program. Other contributors were Min Feng from Brown; Chaoshan Wu, Liqun Guo, Zhaoyang Chen, Samprash Risal and Zheng Fan from UH; and Qing Ai and Jun Lou from Rice.

University of Houston archaeologists make history with Mayan tomb discovery

History in the Making

Two University of Houston archaeologists have made scientific history with the discovery of a Mayan king's tomb in Belize.

The UH team led by husband and wife scientists Arlen F. Chase and Diane Z. Chase made the discovery at Caracol, the largest Mayan archeological site in Belize, which is situated about 25 miles south of Xunantunich and the town of San Ignacio. Together with Belize's Institute of Archeology, as well as support from the Geraldine and Emory Ford Foundation and the KHR Family Fund, they uncovered the tomb of Caracol's founder, King Te K’ab Chaak. Their work used airborne light detection and ranging technology to uncover previously hidden roadways and structures that have been reclaimed by the jungle.

The tomb was found at the base of a royal family shrine. The king, who ascended the throne in 331 AD, lived to an advanced enough age that he no longer had teeth. His tomb held a collection of 11 pottery vessels, carved bone tubes, jadeite jewelry, a mosaic jadeite mask, Pacific spondylus shells, and various other perishable items. Pottery vessels found in the chamber depict a Maya ruler wielding a spear as he receives offerings from supplicants represented as deities; the figure of Ek Chuah, the Maya god of traders, surrounded by offerings; and bound captives, a motif also seen in two related burials. Additionally, two vessels had lids adorned with modeled handles shaped like coatimundi (pisote) heads. The coatimundi, known as tz’uutz’ in Maya, was later adopted by subsequent rulers of Caracol as part of their names.

During the Classical Period, Caracol was one of the main hubs of the Mayan Lowlands and covered an area bigger than that of present-day Belize City. Populations survived in the area for at least 1,000 years before the city was abandoned sometime around 900 AD. The royal dynasty established by Te K’ab Chaak continued at Caracol for over 460 years.

The find is also significant because this was roughly when the Mexican city of Teotihuacan made contact with Caracol, leading to a long relationship of trade and cultural exchange. Cremation sites found in Caracol contain items that would have come from Teotihuacan, showing the relationship between the two distant cities.

"Both central Mexico and the Maya area were clearly aware of each other’s ritual practices, as reflected in the Caracol cremation," said Arlen F. Chase, professor and chair of Comparative Cultural Studies at the University of Houston.

“The connections between the two regions were undertaken by the highest levels of society, suggesting that initial kings at various Maya cities — such as Te K’ab Chaak at Caracol — were engaged in formal diplomatic relationships with Teotihuacan.”

The Chases will present their findings at a conference on Maya–Teotihuacan interaction hosted by the Maya Working Group at the Santa Fe Institute in New Mexico in August 2025.
