Back in April, we ran a series of useful and/or somewhat goofy prompts through Google’s (then-new) PaLM-powered Bard chatbot and OpenAI’s (slightly older) ChatGPT-4 to see which AI chatbot reigned supreme. At the time, we gave the edge to ChatGPT on five of seven trials, while noting that “it’s still early days in the generative AI business.”

Now, the AI days are a bit less “early,” and this week’s launch of a new version of Bard powered by Google’s new Gemini language model seemed like a good excuse to revisit that chatbot battle with the same set of carefully designed prompts. That’s especially true since Google’s promotional materials emphasize that Gemini Ultra beats GPT-4 in “30 of the 32 widely used academic benchmarks” (though the more limited “Gemini Pro” currently powering Bard fares significantly worse in those not-completely-foolproof benchmark tests).

This time around, we decided to compare the new Gemini-powered Bard to both ChatGPT-3.5—for an apples-to-apples comparison of both companies’ current “free” AI assistant products—and ChatGPT-4 Turbo—for a look at OpenAI’s current “top of the line” waitlisted paid subscription product (Google’s top-level “Gemini Ultra” model won’t be publicly available until next year). We also looked at the April results generated by the pre-Gemini Bard model to gauge how much progress Google’s efforts have made in recent months.

Google Podcasts has been sitting on Google’s death row for a few months now since the September announcement. Now, a new support article details Google’s plans to kill the product, with a shutdown coming in April 2024.

Google Podcasts (2016–2024) is Google’s third attempt at a podcasting app after the Google Reader-powered Google Listen (2009–2012) and Google Play Music Podcasts (2016–2020). The product is being shut down in favor of podcast app No. 4, YouTube Podcasts, which launched in 2022.

Google support article details how you can take your subscriptions with you. If you want to move from Google Podcasts to YouTube Podcasts, Google makes that pretty easy with a one-click button at music.youtube.com/transfer_podcasts. If you want to leave the Google ecosystem for something with less of a chance of being shut down in three to four years, you can also export your Google Podcast subscriptions as an OPML file at podcasts.google.com/settings. Google says exports will be available until August 2024.

Modern EVs have some pretty huge batteries, but like their gas-powered counterparts, the main thing they do is sit in one place, unused. The Ford F-150 Lightning was built with two-way power in mind, and soon it might have a use outside emergency scenarios.

Ford and Resideo, a Honeywell Home thermostat brand, recently announced the EV-Home Power Partnership. It’s still in the testing phases, but it could help make EVs a more optimal purchase. Put simply, you could charge your EV when it’s cheap, and when temperatures or demand make grid power time-of-use expensive (or pulled from less renewable sources), you could use your truck’s battery to power the AC. That would also help with grid reliability, should enough people implement such a backup.

The F-150 Lightning already offers a whole-home backup power option, one that requires the professional installation of an 80-amp Ford Charge Station Pro and a home transfer switch to prevent problems when the grid switches back on. Having a smart thermostat allows for grid demand response, so the F-150 would be able to more actively use its vehicle-to-home (V2H) abilities.

In his petition asking the Supreme Court to hear the case, Musk said the SEC settlement forced him to “waive his First Amendment rights to speak on matters ranging far beyond the charged violations.”

The SEC case began after Musk’s August 2018 tweets stating, “Am considering taking Tesla private at $420. Funding secured” and “Investor support is confirmed. Only reason why this is not certain is that it’s contingent on a shareholder vote.” The SEC sued Musk and Tesla, saying the tweets were false and “led to significant market disruption.”

Marbled paper is an art form that dates back at least to the 17th century, when European travelers to the Middle East brought back samples and bound them into albums. Its visually striking patterns arise from the complex hydrodynamics of paint interacting with water, inspiring a winning video entry in this year’s Gallery of Fluid Motion.

The American Physical Society’s Division of Fluid Dynamics sponsors the gallery each year as part of its annual meeting, featuring videos and posters submitted by scientists from all over the world. The objective is to highlight “the captivating science and often breathtaking beauty of fluid motion” and to “celebrate and appreciate the remarkable fluid dynamics phenomena unveiled by researchers and physicists.”

The three videos featured here are the winners of the Milton Van Dyke Awards, which also included three winning posters. There were three additional general video winners—on the atomization of impinging jets, the emergent collective motion of condensate droplets, and the swimming motion of a robotic eel—as well as three poster winners. You can view all the 2023 entries (winning and otherwise) here.

Google is facing controversy among AI experts for a deceptive Gemini promotional video released Wednesday that appears to show its new AI model recognizing visual cues and interacting vocally with a person in real time. As reported by Parmy Olson for Bloomberg, Google has admitted that was not the case. Instead, the researchers fed still images to the model and edited together successful responses, partially misrepresenting the model’s capabilities.

“We created the demo by capturing footage in order to test Gemini’s capabilities on a wide range of challenges,” a spokesperson said. “Then we prompted Gemini using still image frames from the footage, & prompting via text,” a Google spokesperson told Olson. As Olson points out, Google filmed a pair of human hands doing activities, then showed still images to Gemini Ultra, one by one. Google researchers interacted with the model through text, not voice, then picked the best interactions and edited them together with voice synthesis to make the video.

Right now, running still images and text through massive large language models is computationally intensive, which makes real-time video interpretation largely impractical. That was one of the clues that first led AI experts to believe the video was misleading.

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.

On November 22, a few days after OpenAI fired (and then re-hired) CEO Sam Altman, The Information reported that OpenAI had made a technical breakthrough that would allow it to “develop far more powerful artificial intelligence models.” Dubbed Q* (and pronounced “Q star”) the new model was “able to solve math problems that it hadn’t seen before.”

Reuters published a similar story, but details were vague.

Both outlets linked this supposed breakthrough to the board’s decision to fire Altman. Reuters reported that several OpenAI staffers sent the board a letter “warning of a powerful artificial intelligence discovery that they said could threaten humanity.” However, “Reuters was unable to review a copy of the letter,” and subsequent reporting hasn’t connected Altman’s firing to concerns over Q*.

The problem was, I was never ready to attack until I had my base perfectly in order—until the workers carrying oil or crystals or whatnot had the most efficient route from the mine to the base or until my buildings were arranged for optimal use of the revealed land. I just needed one more little guy, one more tower. OK, maybe two. I’m a turtler’s turtler.

Vega has a missing parts problem. In unhappy news for Italian rocket-maker Avio, two of the four propellant tanks on the fourth stage of the Vega rocket—the upper stage, which is powered by dimethylhydrazine and nitrogen tetroxide fuel—went missing earlier this year. Now, it seems that the propellant tanks have been found. However, Ars reports, the tanks were recovered in a dismal state, crushed alongside metal scraps in a landfill. This is a rather big problem for Avio, as this was to be the final Vega rocket launched, and the production lines are now closed for this hardware.

While it may be the reason behind tires skidding, pipes bursting, and closed roads making traffic a nightmare, ice doesn’t always form as easily as it seems. It often gets an assist from proteins made by fungi. 

Never mind the common thinking that ice forms at 0° C (32° F). Though this is water’s freezing point, pure water will only freeze when temperatures plummet as low as minus 46° C (minus 50.8° F). So why does it usually freeze at zero anyway? Organisms such as bacteria, insects, and fungi produce proteins known as ice nucleators (non-protein nucleators can also be of abiotic origin). These proteins can kick-start the formation, or nucleation, of ice at higher temperatures than pure water would freeze at.

While the exact reason fungi make these proteins remains unknown, researchers Valeria Molinero of the University of Utah and Konrad Meister of Boise State University led a study that has revealed more about how fungal ice nucleators can both promote and hold back ice formation more efficiently than those of many other life-forms.

Google is dealing with its second “lost data” fiasco in the past few months. This time, it’s Google Drive, which has been mysteriously losing files for some people. Google acknowledged the issue on November 27, and a week later, it posted what it called a fix.

It doesn’t feel like Google is describing this issue correctly; the company still calls it a “syncing issue” with the Drive desktop app versions 84.0.0.0 through 84.0.4.0. Syncing problems would only mean files don’t make it to or from the cloud, and that doesn’t explain why people are completely losing files. In the most popular issue thread on the Google Drive Community forums, several users describe spreadsheets and documents going missing, which all would have been created and saved in the web interface, not the desktop app, and it’s hard to see how the desktop app could affect that. Many users peg “May 2023” as the time documents stopped saving. Some say they’ve never used the desktop app.

Drive has multiple ways of syncing files, which complicates any explanation or diagnosis of what’s going on. The most suspect mode in the whole fiasco is the default “file streaming,” mode which is actually cloud-first. Files get removed from your computer and stored in the cloud, saving space and leaving only a web link in their place. Perhaps a “syncing” issue could remove files from your computer before uploading (that still doesn’t explain the claims of missing web documents, though).

A small fleet of rideshare Fiat 500e electric vehicles will become testbeds for battery-swap technology in 2024. The experiment is being conducted by Ample, a startup working on battery swaps, and Stellantis, Fiat’s parent company, the Verge reported today.

This isn’t Ample’s first test of its battery-swapping technology; in 2021 it started a small trial in the Bay Area to demo its modular battery, which replaces the existing traction battery in an EV and allows Ample’s automated swap stations to switch out depleted packs for charged ones. But the fact that this deal was made with an OEM like Stellantis is still significant.

As we detailed last time we looked at Ample’s technology, the EVs require some engineering work for this to all be possible. Ample has to design a structural frame to replace the existing battery pack that will instead contain the swappable modules, while still conforming to the engineering requirements of the original pack—down to the same fasteners, bolts, and connectors.

Three short HP video ad campaigns detailed by Marketing Communication News include one with a customer supremely frustrated with his printer’s low ink warning. He kicks his hardware off the table before words appear saying, “No more low ink with HP ink solutions.” Another HP video brags of “no more installation fails” and points to HP’s Smart app. Both of these claims fall apart with a look at HP’s recent and poorly executed firmware rollouts.

The shutdown is scheduled for February 27, 2024, Twitch CEO Dan Clancy announced on Tuesday. Transmitting data in Korea “is prohibitively expensive” despite the company’s efforts to reduce data usage, he wrote.

“First, we experimented with a peer-to-peer model for source quality. Then, we adjusted source quality to a maximum of 720p. While we have lowered costs from these efforts, our network fees in Korea are still 10 times more expensive than in most other countries. Twitch has been operating in Korea at a significant loss, and unfortunately there is no pathway forward for our business to run more sustainably in that country,” Clancy wrote.
