Taco Bell's AI Drive-Thru Plan Gets Caught Up On Trolls and Glitches

Slashdot.org - Fri, 08/29/2025 - 05:00
Taco Bell's rollout of AI-powered drive-thru assistants has run into problems, with glitches and trolls gaming the system by making absurd orders like thousands of water cups. It's so bad that the company is reconsidering where and how to deploy the tech, admitting it may not work well in "super busy" restaurants. "We're learning a lot, I'm going to be honest with you," Dane Mathews, Taco Bell's chief digital and technology officer, told the WSJ. "I think like everybody, sometimes it lets me down, but sometimes it really surprises me." The Verge reports: Since announcing plans to put AI in the drive-thru last year, Taco Bell has deployed the tech in over 500 locations across the US, according to the WSJ. Other fast-food chains are experimenting with AI, too, including McDonald's, Wendy's, and White Castle. Mathews tells the outlet that while the company still plans on pushing ahead with AI voice technology and evaluating the data, he's discovered that using AI exclusively in certain situations, like a drive-thru for "super busy restaurants with long lines," might not be such a great idea after all.

Nanoparticles Turn Houseplants Into Night Lights

Slashdot.org - Fri, 08/29/2025 - 02:00
Longtime Slashdot reader cristiroma shares a report from New Atlas: Wouldn't it be great if the plants in your home could do more than just sit there looking pretty? Researchers at South China Agricultural University in the city of Guangzhou have found a way to upgrade them into soft glowing night lights in a range of hues, with the use of nanoparticles. The team developed a light-emitting phosphor compound that enabled succulents with fleshy leaves to charge in sunlight or indoor LED light in just a couple of minutes, and then emit a soft uniform glow that lasts up to two hours. The afterglow phosphor compound -- which is similar to those found in glow-in-the-dark toys -- is inexpensive, biocompatible, and negates the need for more complex methods of infusing bioluminescence in plants, like genetic modification. It simply gets injected into the leaves. [...] Beyond modifying a commercial compound for this project, the team also had to figure out the right size for the phosphor particles so they'd work as intended inside plants. Shuting Liu, first author on the study that appeared in Matter this week, noted, "Smaller, nano-sized particles move easily within the plant but are dimmer. Larger particles glowed brighter but couldn't travel far inside the plant." Through extensive testing, the researchers arrived at an optimal size of around 7 micrometers, about the width of a red blood cell. They also determined through experimentation that the particles worked best in succulents, rather than plants with thinner leaves like bok choy. Once they'd landed on the right particle size, loading concentration, and plant type, the team found that the phosphor material diffused into succulent leaves almost instantly, and uniformly lit up entire leaves -- enough to illuminate nearby objects. The scientists were also able to create modified phosphors that glowed in colors like green, red, and blue. That could make for novel indoor or garden decor, as well as pathway lighting. These luminous plants also don't cost much -- according to Liu, "Each plant takes about 10 minutes to prepare and costs a little over 10 yuan (about $1.4), not including labor." Over the course of 10 days, the injected plants didn't show any signs of damage, yellowing, structural integrity, or even reduced levels of chlorophyll.

Florida Deploys Robot Rabbits To Control Invasive Burmese Python Population

Slashdot.org - Thu, 08/28/2025 - 22:30
An anonymous reader quotes a report from CBS News: They look, move and even smell like the kind of furry Everglades marsh rabbit a Burmese python would love to eat. But these bunnies are robots meant to lure the giant invasive snakes out of their hiding spots. It's the latest effort by the South Florida Water Management District to eliminate as many pythons as possible from the Everglades, where they are decimating native species with their voracious appetites. In Everglades National Park, officials say the snakes have eliminated 95% of small mammals as well as thousands of birds. "Removing them is fairly simple. It's detection. We're having a really hard time finding them," said Mike Kirkland, lead invasive animal biologist for the water district. "They're so well camouflaged in the field." The water district and University of Florida researchers deployed 120 robot rabbits this summer as an experiment. Previously, there was an effort to use live rabbits as snake lures but that became too expensive and time-consuming, Kirkland said. The robots are simple toy rabbits, but retrofitted to emit heat, a smell and to make natural movements to appear like any other regular rabbit. "They look like a real rabbit," Kirkland said. They are solar powered and can be switched on and off remotely. They are placed in small pens monitored by a video camera that sends out a signal when a python is nearby. "Then I can deploy one of our many contractors to go out and remove the python," Kirkland said. The total cost per robot rabbit is about $4,000, financed by the water district, he added.

Amtrak's New 160mph Acela Trains Take Just As Long As the Old Ones

Slashdot.org - Thu, 08/28/2025 - 21:02
Amtrak's new 160 mph tilting Acela trains have debuted on the Northeast Corridor, offering smoother rides, upgraded interiors, faster Wi-Fi, and 27% more seating capacity. However, "they don't complete the journey any faster than the old trains," reports The Independent. From the report: Acela runs from Washington, DC's Union Station to Boston via Philadelphia, New York Penn Station, New Haven, and Providence. It's a total distance of 457 miles, with the fastest next-gen Acela journey being six hours and 43 minutes, five minutes slower than the quickest end-to-end time offered by the old Acela trains, introduced in 2000. However, this may be because, as is common practice with new trains the world over, Amtrak is scheduling longer dwell times at stations so staff and passengers can adjust to them. The next-gen sets have a top service speed that's 10mph faster -- though this can only be achieved on certain sections of the mostly 110mph route -- and an enhanced "anticipative" tilting system that allows for higher speeds through curves.

Microsoft Reveals Two In-House AI Models

Slashdot.org - Thu, 08/28/2025 - 20:25
Today, Microsoft unveiled two in-house AI models: MAI-Voice-1, a high-speed speech-generation system now live in Copilot, and MAI-1-Preview, its first end-to-end foundation model trained on 15,000 H100 GPUs. Neowin reports: MAI-Voice-1 is a speech generation model and is already available in Copilot Daily and Podcasts. To preview the full capabilities of this voice model, Microsoft has created a new Copilot Labs experience that anyone can try today. With the Copilot Audio Expressions experience, users can just paste text content and select the voice, style, and mode to generate high-fidelity, expressive audio. They can also download the generated audio if required. Microsoft also highlighted that this MAI-Voice-1 model is very fast and efficient. In fact, it can generate a full minute of audio in under a second on a single GPU. Second, Microsoft has begun public testing of MAI-1-preview on LMArena, a popular platform for community model evaluation. This represents MAI's first foundation model trained end-to-end and offers a glimpse of future offerings inside Copilot. They are actively spinning the flywheel to deliver improved models and will have much more to share in the coming months. MAI-1-preview is an MoE (mixture-of-experts) model, pre-trained and post-trained on nearly 15,000 NVIDIA H100 GPUs. Notably, MAI-1-preview is Microsoft's first foundation model trained end-to-end in-house. Microsoft claims that this model is better at following instructions and can offer helpful responses to everyday user questions. Microsoft will be rolling out this new model to certain text use cases within Copilot over the coming weeks.

Stellantis Shelves Level 3 Driver-Assistance Program

Slashdot.org - Thu, 08/28/2025 - 19:02
Stellantis has put its fully developed Level 3 driver-assistance system on hold due to high costs, technical hurdles, and weak consumer demand. Reuters reports: As recently as February, Stellantis said its in-house system, which is part of the AutoDrive program, was ready for deployment and a key pillar of its strategy. The company said the system, which enables drivers to have their hands off the wheel and eyes off the road under certain conditions, would allow them to temporarily watch movies, catch up on emails, or read books. That Level 3 software was never launched, the company confirmed to Reuters. But it stopped short of saying that the program was canceled. "What was unveiled in February 2025 was L3 technology for which there is currently limited market demand, so this has not been launched, but the technology is available and ready to be deployed," a Stellantis spokesperson said. The three sources, however, said that the program was put on ice and is not expected to be deployed. When asked how much time and money was lost on the initiative, Stellantis declined to say, responding that the work done on AutoDrive will help support its future versions. [...] Stellantis said it is leaning on aiMotive, a tech startup it acquired in 2022, to deliver the next generation of the AutoDrive program. Stellantis declined to say when that program would be ready for market or if it would include Level 3 capability.
