As we reported a month ago, the Cybertruck-only clause was added to the public version of Tesla’s Motor Vehicle Order Agreement Terms & Conditions and then deleted after the lawsuit threat attracted some attention. But now, people who ordered the limited launch edition “Foundation Series” Cybertruck say the order agreement they received from Tesla has the clause added back in.

The clause says Cybertruck buyers must offer the car back to Tesla at a reduced price before any attempt to resell the vehicle within one year of delivery. If Tesla declines to buy the Cybertruck back, the owner could resell it only if Tesla provides “written consent.”

Grok, the AI language model created by Elon Musk’s xAI, went into wide release last week, and people have begun spotting glitches. On Friday, security tester Jax Winterbourne tweeted a screenshot of Grok denying a query with the statement, “I’m afraid I cannot fulfill that request, as it goes against OpenAI’s use case policy.” That made ears perk up online since Grok isn’t made by OpenAI—the company responsible for ChatGPT, which Grok is positioned to compete with.

Interestingly, xAI representatives did not deny that this behavior occurs with its AI model. In reply, xAI employee Igor Babuschkin wrote, “The issue here is that the web is full of ChatGPT outputs, so we accidentally picked up some of them when we trained Grok on a large amount of web data. This was a huge surprise to us when we first noticed it. For what it’s worth, the issue is very rare and now that we’re aware of it we’ll make sure that future versions of Grok don’t have this problem. Don’t worry, no OpenAI code was used to make Grok.”

In reply to Babuschkin, Winterbourne wrote, “Thanks for the response. I will say it’s not very rare, and occurs quite frequently when involving code creation. Nonetheless, I’ll let people who specialize in LLM and AI weigh in on this further. I’m merely an observer.”

This month, JEDEC, a semiconductor engineering trade organization, announced that it had published the JESD318: Compression Attached Memory Module (CAMM2) standard, as spotted by Tom’s Hardware.

CAMM2 was originally introduced as CAMM via Dell, which has been pushing for standardization since it announced the technology at CES 2022. Dell released the only laptops with CAMM in 2022, the Dell Precision 7670 and 7770 workstations.

Oil-producing countries are apparently succeeding in their attempts to eliminate language from an international climate agreement that calls for countries to phase out the use of fossil fuels. Draft forms of the agreement had included text that called upon the countries that are part of the Paris Agreement to work toward “an orderly and just phase out of fossil fuels.” Reports now indicate that this text has gone missing from the latest versions of the draft.

The agreement is being negotiated at the United Nations’ COP28 climate change conference, taking place in the United Arab Emirates. The COP, or Conference of the Parties, meetings are annual events that attempt to bring together UN members to discuss ways to deal with climate change. They were central to the negotiations that brought about the Paris Agreement, which calls for participants to develop plans that should bring the world to net-zero emissions by the middle of the century.

Initial plans submitted by countries would lower the world’s greenhouse gas emissions, but not by nearly enough to reach net zero. However, the agreement included mechanisms by which countries would continue to evaluate their progress and submit more stringent goals. So, additional COP meetings have included what’s termed a “stocktake” to evaluate where countries stand, and statements are issued to encourage and direct future actions.

Google Play Movies & TV is getting a shutdown date, again. Google previously sent out an email to users saying “Google Play Movies & TV is going away on 05 October 2023,” but 9to5Google spotted a new support page that now says January 17, 2024, is the new shutdown date. It’s not entirely clear why we got two different shutdown dates, but the October 5 shutdown definitely happened in the US; perhaps this message is for international users.

Google’s page says that in January, “Google Play Movies & TV will no longer be available on Android TV devices or the Google Play website.” This should be the last of the Google Play Movies brand. Phones and tablets have already switched over to a “Google TV” app (not to be confused with the Google TV OS), and the Play Store abandoned media sales in 2022.

With the one-stop-shop Play Store dead, Google says your purchased content will now be in different apps, depending on what Google platform you’re on. The support page says: “On TVs and streaming devices powered by Android TV,” purchased content is in the “Shop” tab but on “cable boxes or set-top boxes powered by Android TV” the content will be in the YouTube app. On the web, purchased content is on YouTube.com.

“Emergency physician Elise Tiebie, the driving force behind this project, saw online that this was really a rumor, from tip websites to Wikipedia as well as an anecdote in a British newspaper about paramedics saving a life by using cola. I’ve even heard doctors recommending it,” said co-author Arjan Bredenoord, a gastroenterologist at Amsterdam University Medical Centers. Getting food stuck in one’s esophagus “can be really dangerous, so it’s important that people get the correct treatment,” he added. “That’s why we wanted to check if this works.”

The technical term is “esophageal food bolus obstruction,” more commonly known as “steakhouse syndrome” or “backyard barbecue syndrome.” It’s usually pieces of poorly masticated meat (steak, poultry, pork) that get stuck, and when that happens, the unfortunate soul will have trouble swallowing to the point of drooling (since they can’t even swallow their saliva). They may also have chest or neck pain, and there’s always the chance that the esophagus will be perforated, leading to aspiration into the lungs. Hence, a trip to the ER is necessary.

Musk restored the @RealAlexJones account after polling X users. With almost 2 million votes, about 70 percent of users supported reinstating Jones, who was banned by Twitter in 2018.

“I vehemently disagree with what he said about Sandy Hook, but are we a platform that believes in freedom of speech or are we not? That is what it comes down to in the end. If the people vote him back on, this will be bad for X financially, but principles matter more than money,” Musk wrote on Saturday. Musk also spoke with Jones about his Sandy Hook comments in a live interview on X.

Electrification is a big challenge if you’re a small automaker. And Mazda is a small automaker, one that’s in danger of being caught out by a range of inefficient gasoline- and diesel-powered vehicles. But the Japanese company hasn’t given up on electric vehicles, it says. In an interview with Auto News, Mazda CEO Masahiro Moro says the company will be an “intentional follower” in this space and that questionable demand for EVs justifies this strategy.

“One of the big issues for us is demand is uncertain,” Moro said. “In the current market, the reality for electrification, in particular for battery EVs, is the pace is not that high. So we may start a little slower in terms of the ramp-up. Not necessarily in terms of timing, but the ramp-up.”

In time, we should see a family of new Mazda-designed EVs built on a new platform. But the division that has to design them, called e-Mazda, was only created in November. Moro told Auto News that the division will focus on making EVs lighter and more affordable but won’t develop compact or smaller EVs as the cost of batteries makes them unprofitable.

BOLOGNA, ITALY—For decades, owning an Italian motorcycle required a tradeoff. On one hand, Italian bikemakers led the pack with gorgeous designs and the most exotic, highest-performing engines in the world. No other country could come close to matching the sounds and smells of a Ducati, Moto Guzzi, or Aprilia revving by. But build quality and reliability always presented a challenge for owners, not to mention parts availability and exorbitant maintenance costs.

Ducati arguably led the charge in every regard, setting a standard as the Ferrari of the motorcycle world with eye-catching Rosso Corsa red paint jobs to go along with real racing success in MotoGP and World Superbike thanks to famous—some might say infamous—desmodromic engines. However, In recent years under Volkswagen Group’s ownership, Ducati has made great strides in reliability and build quality, which explains to a large extent why 2022 was the firm’s most profitable year ever, with 62,000 bikes sold worldwide.

During a recent trip to Italy, I visited the Ducati factory in Bologna to learn how modernizing the production facility at Borgo Panigale helped improve the bikes built there over the decade since joining the Volkswagen group.

Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We’ll let other publications offer you a daily horoscope. At Ars Technica, we’re going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.

I know there are people who will want to buy the Homey Pro. I’ve seen them on social media and in various home automation forums, and I’ve even noticed them in the comments on this website. For this type of person, the Homey Pro might serve as a specialized, locally focused smart home hub, one that’s well worth the cost. But you should be really, truly certain that you’re that person before you take a $400 leap with it.

Homey Pro is a smart home hub pitched primarily at someone who wants to keep things local as much as possible, forgoing phone apps, speakers, and cloud connections. That means using the Homey Pro to boost a primarily Zigbee or Z-Wave network, while also looping in local Wi-Fi, Bluetooth, and even infrared remotes. It’s for someone willing to pay $400 for a device that offers robust local or cloud backups, professional design, advanced automation, and even a custom scripting language, along with access to some “experiments” and still-in-progress tech like Matter and Thread. It’s for someone who might want to add a select cloud service or two to their home, but not because they have no other option.

But this somebody has also, somehow, not already invested in Home Assistant, Hubitat, or HomeBridge, which are more open to both add-on hardware (like new capabilities added on by USB stick or GPIO pins) and deep tinkering. It’s someone who is willing to check that every device they want to control will work with Homey. While the device offers a pretty sizable range of apps and integrations, it’s far from the near-universal nature of major open-source projects or even the big smart home platforms. And you have to do a little checking further, still, to ensure that individual products are supported, not just the brand.

The launch company’s chief executive, Tory Bruno, announced the delay on the social media site X on Sunday. United Launch Alliance had been working toward a debut flight of the lift booster on Christmas Eve, from Cape Canaveral Space Force Station in Florida.

Bruno made the announcement after the company attempted to complete a fueling test of the entire rocket, known as a wet dress rehearsal.

Women and girls across much of the developing world lack access to menstrual products. This means that for at least a week or so every month, many girls don’t go to school, so they fall behind educationally and often never catch up economically. 

Many conventional menstrual products have traditionally been made of hydrogels made from toxic petrochemicals, so there has been a push to make them out of biomaterials. But this usually means cellulose from wood, which is in high demand for other purposes and isn’t readily available in many parts of the globe. So Alex Odundo found a way to solve both of these problems: making maxi pads out of sisal, a drought-tolerant agave plant that grows readily in semi-arid climates like his native Kenya.

Putting an invasive species to work

Sisal is an invasive plant in rural Kenya, where it is often planted as livestock fencing and feedstock. It doesn’t require fertilizer, and its leaves can be harvested all year long over a five- to seven-year span. Odundo and his partners in Manu Prakash’s lab at Stanford University developed a process to generate soft, absorbent material from the sisal leaves. It relies on treatment with dilute peroxyformic acid (1 percent) to increase its porosity, followed by washing in sodium hydroxide (4 percent) and then spinning in a tabletop blender to enhance porosity and make it softer.

When Ars first drove the then-new Ford Mustang Mach-E back in early 2021, the car was an attention magnet. Now, almost three years later, the Mustang Mach-E is a much more common sight on our roads, but so are other electric crossovers from most of Ford’s usual rivals, including the sales juggernaut that is the Tesla Model Y. We decided to book a few days with a Mustang Mach-E to see how (or if) this equine EV has matured since launch.

Originally, Ford had been working on a much more boring battery electric car until Tesla started delivering its Model 3s, at which point a hastily convened “Team Edison” set to work adding some much-needed brio to the design, rethinking Ford’s EV strategy in the process.

Giving this midsize crossover EV a Mustang name tag remains divisive—I expect a reasonable percentage of comments to this story will be people showing up to complain, “It ain’t no real Mustang.” The crossover’s name is what it is, and there are plenty of Mustang styling cues, but even with the designers’ trick of using black trim to make you ignore the bits they don’t want you to see, there’s no denying the proportions are pretty far from coupe-like.
