Scientists use stem cells to grow animal-free pork in a lab

A new study published in the journal Scientific Reports has taken us one step closer to the dream of animal-free meat. (And, no, in case your mind immediately goes to the 1973 sci-fi movie Soylent Green, it ain’t people, either!)

“What the paper describes is research designed to generate muscle from a newly established pig stem-cell line, rather that from primary cells taken directly from a pig,” co-author Dr. Nicholas Genovese, a stem-cell biologist (and vegetarian), told Digital Trends. “This entailed understanding the biology of relatively uncharacterized and recently-derived porcine induced pluripotent stem cell lines. What conditions support cell growth, survival and differentiation? These are all questions I had to figure out in the lab before the cells could be turned into muscle.”

As you can imagine, this wasn’t straightforward.

“It was exceptionally [distressing] when conditions I thought would support differentiation caused all of the cells to die,” Genovese continued. “But fortunately I was able to identify a solution that would allow the stem cells to survive, allowing their transition to skeletal muscle.”

It may not sound like the most appetizing of foodstuffs, but pig skeletal muscle is in fact the main component of pork. The fact that it could be grown from a stem-cell line, rather than from a whole pig, is a major advance. This is also true of the paper’s second big development: the fact that this cultivation of pig skeletal muscle didn’t use animal serum, a component which has been used in other livestock muscle cultivation processes.

Genovese is the chief science officer and co-founder of Memphis Meats, a foodie startup which aims to grow edible meat in a lab. Having last year debuted a lab-grown meatball, the company is now working on developing other meats and scaling its business.

“My motivation originates from exploring better ways to produce meat,” Genovese said. “Environmental degradation, food safety, food security, emerging infectious disease, and animal suffering are all challenges becoming increasingly relevant due to the increasing global demand for conventionally produced animal products, especially meat. An innovative solution to this dilemma, was, and remains, my core motivation.”

He also acknowledges that there are other non-food-related possibilities the work hints at. “There is a contingent interest in using the pig as a model to study disease and test regenerative therapies for human conditions,” he said.

While we’re still a way away from lab-grown meat being readily available and affordable (the aforementioned meatball cost $1,200 to grow), the plan is for this to happen over the next 5-10 years. In other words, Memphis Meats is a startup worth keeping an eye on.

Cadillac offers first glimpse of upcoming Optiq-V performance EV
cadillac optiq v teaser ev

Cadillac has released the first official teaser images of the 2026 Optiq-V, offering a preview of the brand’s second all-electric model to join the performance-focused V-Series lineup. The images, which highlight subtle styling upgrades, mark the first confirmation of the new variant ahead of its full reveal later this year.
The Optiq-V builds on the foundation of the standard Optiq, Cadillac’s compact electric SUV introduced for the 2025 model year. According to the automaker, this V-Series version will feature a more dynamic driving experience, with enhancements to steering, suspension, and overall agility. While technical details remain limited, Cadillac’s press release emphasizes that the Optiq-V was engineered for “precision” and an “exhilarating” feel behind the wheel.
Reports from CarScoops suggest the Optiq-V could produce up to 515 horsepower through a dual-motor all-wheel-drive system, significantly surpassing the 300 horsepower of the base model. Teaser images reveal a diamond-pattern mesh grille, V-Series badging, and a rear spoiler — all nods to its performance orientation. Photos also hint at additional visual updates, such as redesigned bumpers, 21-inch wheels, and larger brakes.
The base Optiq, reviewed recently by Digital Trends, is positioned as Cadillac’s entry-level EV and shares its underpinnings with the Chevrolet Equinox EV. Despite that connection, the Optiq features premium materials, a curved 33-inch display, Google built-in tech, and standard dual-motor all-wheel drive. While the review noted some drawbacks in steering feel and performance tuning, it praised the vehicle's cabin quality and overall comfort.
The Optiq-V is expected to retain the standard model’s 85-kWh battery and roughly 300-mile range, though final figures have yet to be announced. Cadillac says more details on specs and pricing will be available closer to the model’s official launch.
With the addition of the Optiq-V, Cadillac continues expanding its electric lineup while reinforcing its V-Series as a key part of its identity — now in the EV era.

Nissan delays price increases until June amid U.S. tariffs
nissan rogue hybrid 2025 2024

Nissan buyers, take note: if you're eyeing a new ride, you might want to make your move before summer. The automaker has announced it won’t raise prices on imported vehicles until at least June 2, giving car shoppers a brief reprieve from the impact of the new 25% U.S. import tariffs.
According to a memo sent to U.S. dealers and reported by Automotive News, Nissan is able to hold prices steady thanks to a stockpile of tariff-free vehicles—enough to last nearly three months. But once that inventory runs dry? Prices are likely heading north. Nissan’s U.S. sales chief Vinay Shahani assured dealers that the company is working to "minimize the impact" of tariffs on customers, but he was also frank: “There will be an impact.”
To soften the blow, Nissan is ramping up production at its U.S. plants in Smyrna, Tennessee, and Canton, Mississippi. Those factories were only running at about half capacity last year, so there’s plenty of room to grow. The Rogue—Nissan’s best-seller—will get a second shift on its assembly line, increasing production by about 60,000 vehicles. Other models like the Pathfinder, Frontier, and Murano will also see higher domestic output.
The goal? Build more cars stateside and dodge the tariff altogether.
Nissan’s move puts it in line with other automakers holding the line on prices—at least for now. Hyundai, Toyota, and Honda have made similar pledges, while rivals like Ford and Stellantis are rolling out temporary discounts to ease the pain.
As Digital Trends noted, Nissan’s decision comes as it rethinks its production and pricing strategy in the face of shifting trade policies and a nervous market. With high-volume imports like the Sentra and Ariya still coming from Mexico and Japan, this pricing grace period might not last long.

Buick, Audi, and Nissan score top marks in latest IIHS safety ratings
2025 Audi Q6 e-tron front quarter view.

The Insurance Institute for Highway Safety (IIHS) has added four more vehicles to its coveted 2025 Top Safety Pick and Top Safety Pick+ lists. If you appreciate knowing your vehicle is built with safety in mind, this update is worth noting.

Among the standout performers: the Audi Q6 e-tron, Buick Enclave, and Nissan Armada—each earning the institute’s highest honor, the Top Safety Pick+ award. The GMC Acadia also made the grade, picking up a Top Safety Pick award. For Buick and GMC, these honors mark a significant return to form, as neither brand had received IIHS awards in several years. In fact, it’s the first time since 2013 that the Enclave has been recognized.
So, how does IIHS hand out these awards? Picture a battery of tests that simulate real-world crashes—everything from small overlap front impacts to updated side crashes. To make the list, vehicles must ace (i.e., earn a “good” rating in) key crashworthiness tests, show competence in pedestrian crash prevention, and offer headlights that don’t blind oncoming drivers. For the higher-tier Top Safety Pick+, there's an extra hurdle: a “good” rating in the updated moderate front overlap test, which now factors in rear-seat passenger protection.
Improvements to the Enclave and Acadia’s headlights, introduced after January 2025, helped push them over the finish line. Unfortunately, not all models in this testing round were so lucky. The Cadillac Lyriq, Audi Q6 Sportback e-tron, Kia K4, and several Nissan models—including the Kicks, Rogue, and Sentra—fell short. Common issues? Poor headlight performance or incomplete testing.
The IIHS notes that these evaluations are ongoing. Not every vehicle released for 2025 has been fully assessed, and late-year updates can still improve a model’s score. For the full list of safety awards, you can check out the IIHS website.
