On Tuesday, Adobe unveiled Firefly, its new AI image synthesis generator. Unlike other AI art models such as Stable Diffusion and DALL-E, Adobe says its Firefly engine, which can generate new images from text descriptions, has been trained solely on legal and ethical sources, making its output clear for use by commercial artists. It will be integrated directly into Creative Cloud, but for now, it is only available as a beta.

Since the mainstream debut of image synthesis models last year, the field has been fraught with issues around ethics and copyright. For example, the AI art generator called Stable Diffusion gained its ability to generate images from text descriptions after researchers trained an AI model to analyze hundreds of millions of images scraped from the Internet. Many (probably most) of those images were copyrighted and obtained without the consent of their rights holders, which led to lawsuits and protests from artists.

To avoid those legal and ethical issues, Adobe created an AI art generator trained solely on Adobe Stock images, openly licensed content, and public domain content, ensuring the generated content is safe for commercial use. Adobe goes into more detail in its news release:

Android is doing a pretty good job of colonizing the in-car infotainment ecosystem. At first, Google's operating system started showing up in new vehicles as custom installations, but more recently the company developed Android Automotive, which you can find in new cars from General Motors, Polestar, Volvo, Honda, and soon, both BMW and Volkswagen Group.

A perennial question that has accompanied the spread of Android Automotive has been the question of support. A car has a much longer expected service life than a smartphone, especially an Android smartphone, and with infotainment systems so integral to a car's operations now, how long can we reasonably expect those infotainment systems to be supported?

So far, a bit more than seven years is the longest any Android phone has received support, before unsupported chips finally called time on the Fairphone. I'm not sure anyone would be OK with having their car sent to the scrap heap after just seven years, however.

Yesterday, about 50 AI-generated images imagining what former President Donald Trump’s arrest would look like spread across Twitter. The images caused confusion for some users because the Midjourney v5 engine used to create them generates such realistic-looking content.

Today, the Midjourney user behind the images—Bellingcat founder Eliot Higgins—alleged to Buzzfeed News that he was banned from Midjourney over the images. Buzzfeed also reported that Midjourney has banned the word “arrest” from being used in text prompts to generate images.

Midjourney has not yet confirmed the ban. An Ars test indicates that prompts using Donald Trump’s name also seem to be blocked on the engine, generating instead an error message saying that the prompt was blocked because “it may conflict with our content policy.” We got the same error message when we used prompts including other Trump family names and all the presidents’ names. However, other celebrity names, like former NFL player Tom Brady, are still seemingly acceptable in prompts.

Two months after dumping Newsmax instead of paying a new fee, DirecTV has reached a deal to put the conservative news network back in the satellite provider's channel lineup.

Newsmax had waged an aggressive public relations campaign against DirecTV. "This is a blatant act of political discrimination and censorship against Newsmax," Newsmax CEO Christopher Ruddy said on January 25 in an article on the network's website.

Newsmax changed its tune today when announcing the deal that will put Newsmax back on DirecTV starting tomorrow. "While we raised the issue of censorship relating to our removal, we now believe in DirecTV's commitment to distributing diverse viewpoints, including conservative ones," Newsmax said in a statement provided to Ars.

Ludwig van Beethoven is one of the greatest composers of all time, but he was plagued throughout his life by myriad health problems, most notably going mostly deaf by 1818. These issues certainly affected his career and emotional state, so much so that Beethoven requested—via a letter addressed to his brothers—that his favorite physician examine his body after his death to determine the cause of all his suffering.

Nearly two centuries after the composer's demise, scientists say they have sequenced his genome based on preserved locks of hair. While the analysis of that genome failed to pinpoint a definitive cause of Beethoven's hearing loss or chronic digestive problems, he did have numerous risk factors for liver disease and was infected with hepatitis B, according to a new paper published in the journal Current Biology. The researchers also found genetic evidence that somewhere in the Beethoven paternal line, an ancestor had an extramarital affair.

“We cannot say definitely what killed Beethoven, but we can now at least confirm the presence of significant heritable risk and an infection with hepatitis B virus,” said co-author Johannes Krause, an expert in ancient DNA at the Max Planck Institute of Evolutionary Anthropology. “We can also eliminate several other less plausible genetic causes.” The fully sequenced genome will be made publicly available so other researchers can have access to conduct future studies.

When it comes to reducing gaming's aggregate impact on climate change, previous research has shown that the energy needed to power the game-playing hardware is responsible for the bulk of the industry's greenhouse gas emissions. That's especially true for console and PC games, which can draw hundreds of watts of power between the game hardware, display, and speakers.

To help limit the environmental impact of all this gameplay, Microsoft announced Wednesday the release of new tools for Xbox developers to measure and limit the amount of power drawn by their games.

Designing games to be more energy-efficient is not a new concept in the industry, of course. Mobile developers often must be conscious of how quickly a game will drain a limited smartphone battery. On the other end of the spectrum, pushing a PC or console GPU too far could literally melt it.
