Most people are familiar with conventional cubical six-sided dice, but there are also polyhedral versions like the 20-sided dice used in ancient Rome and to play Dungeons and Dragons. Researchers have figured out how to design dice with even more exotic shapes, like a kitten, a dragon, or an armadillo. And they are "fair" dice: Experiments with 3D-printed versions produced results that closely matched predicted random outcomes, according to a forthcoming paper currently in press at the journal ACM Transactions on Graphics.

Dice are examples of so-called "rigid bodies," broadly defined as shapes that move as one solid piece, with no need for bending or twisting. Such shapes "are of scientific interest because they model so many of the phenomena we encounter in our daily lives: anything from the way your dishes roll around on the floor when you drop them, to how the gears in your watch push on each other, to how a satellite tumbles around under the pull of gravity," co-author Keenan Crane of Carnegie-Mellon University told Ars. "So there's an intense focus on developing computational methods for understanding and predicting how rigid bodies are going to behave."

Crane and his co-authors—including lead author and CMU graduate student Hossein Baktash, as well as co-authors from Nvidia Research and Adobe Research—wanted to explore where and how a rigid body will land when tossed. They chose dice as the best (and most fun) context in which to explore that question.

The ability to study ancient DNA has revolutionized our ability to understand our own species' past. It has clarified our relationship with Neanderthals and revealed the existence of Denisovans. But even in the most favorable environments, DNA degrades over time, setting a limit on how far back we can hope to resolve questions about our ancestors. And most of the species we've had trouble understanding lived in Africa, where the conditions are far less favorable for DNA's survival.

But a large international team has now found another way to get some information about the genetics out of far older remains. They've extracted fragments of enamel proteins from the teeth of fossils of the species Paranthropus robustus and used them to test whether the remains truly belonged to one species, despite dramatic differences in size. Because one of the proteins is male-specific, they also found the size of the individual wasn't necessarily related to its sex.

A complicated species

Remains that have been classified as Paranthropus show up in the fossil record nearly 3 million years ago and persist for roughly a million years. That means it overlapped both with australopithecines and early members of the Homo genus. Four different species have been assigned to this genus, but the situation is complicated. It shares a lot of similarities with some species of Australopithecus, raising the possibility of interbreeding. There's also a lot of variation within remains identified as Paranthropus, notably in the size of individuals. Some have suggested that this might be due to male/female differences in this species (termed "sexual dimorphism"), but that has been difficult to test.

The latest Mac mini is a tiny computer that packs a high-performance Apple M4 series processor into a tiny chassis that measures just 5″ x 5″ x 2″. It also has a reasonably large number of ports for such as small computer, including Ethernet, HDMI, and audio jacks, two USB Type-C ports, and three Thunderbolt […]

Last week, Google introduced Veo 3, its newest video generation model that can create 8-second clips with synchronized sound effects and audio dialog—a first for the company's AI tools. The model, which generates videos at 720p resolution (based on text descriptions called "prompts" or still image inputs), represents what may be the most capable consumer video generator to date, bringing video synthesis close to a point where it is becoming very difficult to distinguish between "authentic" and AI-generated media.

Google also launched Flow, an online AI filmmaking tool that combines Veo 3 with the company's Imagen 4 image generator and Gemini language model, allowing creators to describe scenes in natural language and manage characters, locations, and visual styles in a web interface.

Both tools are available now to US subscribers of Google AI Ultra, a plan that costs $250 a month and comes with 12,500 credits. Veo 3 videos cost 150 credits per generation, allowing 83 videos on that plan before you run out. Extra credits are available for the price of 1 cent per credit in blocks of $25, $50, or $200. That comes out to about $1.50 per video generation. But is the price worth it? We ran some tests with various prompts to see what this technology is truly capable of.

Nintendo's Switch 2 has a small handful of new releases in its launch lineup, but for the first few months after its release, the main thing you'll be able to play on it will be your existing library of Switch games. And while Nintendo has promised reasonably comprehensive backward compatibility, the company is still working through the process of testing over 15,000 third-party Switch games with the new console.

With a week to go until launch, Nintendo has updated its compatibility support page with the results of nearly two months of extra testing. Of the "over 15,000" third-party Switch games, Nintendo says roughly two-thirds of them either have "no issues" or have problems that will be resolved quickly at or after launch. On the original version of this support page, Nintendo had only performed its basic compatibility testing on roughly 20 percent of all third-party Switch games.

Nintendo says that nearly all of the roughly 5,000 remaining Switch games will launch just fine on the Switch 2 but that "further tests" are "in progress." The support page doesn't say when Nintendo will provide its next update.

Three years ago, pirated Blu-ray copies of “Spider-Man: No Way Home” began circulating on pirate sites, weeks before its official release.

Such high-profile leaks are rare, and the source of the breach remained unknown until earlier this year.

In February, the U.S. Department of Justice indicted 37-year-old Steven Hale from Tennessee, a former employee of a disc manufacturing and distribution company in Memphis. While working at the unnamed company between 2021 and 2022, Hale allegedly stole numerous “pre-release” DVD and Blu-ray discs from his employer.

These stolen discs contained many high-profile movie titles including “Spider-Man: No Way Home”.

Hale Pleads Guilty

Hale initially pleaded not guilty to two criminal copyright infringement charges and an additional charge of interstate transportation of stolen goods. This week Hale changed his plea, admitting guilt to one of the charges, and signing a plea agreement with the prosecution.

Hale entered his guilty plea to Count Two of the indictment. The charge relates to his distribution of ten or more copies of copyrighted works, including pre-release movies, for commercial advantage and private financial gain. This includes the pre-release ‘Spider-Man: No Way Home’ disc, which is likely the source of the leak.

The other films covered by this count are ‘Jungle Cruise,’ ‘Venom: Let There Be Carnage,’ ‘Encanto,’ ‘Eternals,’ ‘The King’s Man,’ ‘Shang-Chi and the Legend of the Ten Rings,’ ‘Resident Evil: Welcome to Raccoon City,’ ‘Marry Me,’ ‘Sing 2,’ and ‘The Matrix Resurrections.’

Lower Sentence, Limited Damages

As part of the agreement, the prosecution agreed to drop two other counts and the Justice Department will recommend that the court awards the maximum available sentence reduction because Hale accepted responsibility. It will also recommend that the defendant is sentenced at the low end of the guideline range.

For the remaining count, Hale faces a potential maximum penalty of five years imprisonment, a $250,000 fine, and three years of supervised release. In addition, he has also agreed to pay restitution to all identifiable victims who suffered losses due to his criminal conduct.

Interestingly, for sentencing guideline purposes, the plea agreement puts the “infringement amount” between $15,000 and $40,000. That’s lower than the tens of millions of dollars in estimated losses mentioned in the indictment related to ‘Spider-Man: No Way Home. The final damages amount has yet to be determined by the court.

1,160 Blu-rays and DVDs

The plea agreement doesn’t add much detail to what is already publicly known. Importantly, however, it does reveal that law enforcement seized approximately 1,160 Blu-rays and DVDs from the defendant on or around March 14, 2022.

This means that the authorities had tracked down Hale as a potential suspect just days after the ‘Spider-Man’ movie leaked online. After that, it took nearly three years before the defendant was indicted.

Why the indictment took so long is unknown, but the case may have been part of a broader ongoing investigation.

Speculation and Sentencing

While one can only speculate beyond this point, it is worth pointing out that the early online leaks of “Spider-Man: No Way Home” were shared publicly by the infamous release group EVO. This group was known for distributing pre-release content.

A few months after the authorities tracked down Hale, EVO was dismantled by the Portuguese authorities. There is no evidence to suggest that these two cases are connected, but it’s not impossible either.

What we do know for sure is that Hale will be sentenced by the District Court of Tennessee later this year. This sentencing hearing is scheduled to take place at the end of August.

Donald Trump can't impose whatever tariffs he wants on a whim, a federal court ruled Wednesday, issuing an opinion that analysts say has only stoked more trade chaos.

The ruling permanently blocked some of the most controversial tariffs and reportedly scrambled Trump's ongoing trade talks with many countries pressured into negotiations by the threat of those tariffs, CNN reported.

The blocked tariffs—which the court found were implemented unconstitutionally under the International Emergency Economic Powers Act (IEEPA)—included tariffs the administration said were designed to stop drug and human trafficking, as well as retaliatory tariffs placed on all countries that were supposed to put an end to persistent US trade deficits.

Discord is further distancing itself from its ad-free beginnings by offering users a new virtual currency for clicking on in-platform advertisements.

Acoording to a blog post this week by Peter Sellis, Discord’s SVP of product, a “small group” of Discord users around the globe can now earn "Orbs" through Play Quests, which Discord announced in March 2024 and let users earn in-game rewards by getting people to watch a stream of them playing a sponsored game. With enough Orbs, Discord users can purchase items in Discord's shop, including customization options for their profiles and credits for Nitro, a subscription add-on that offers features like 500MB uploads and HD resolution streaming.

The goal is to fuel Discord’s advertising business by making clicking on ads more appealing. Advertisers also benefit by associating their ads with the ability to get desirable rewards.

Elon Musk said he is leaving the Trump administration, attributing his departure not to any disagreement with Trump but rather to the legal limit on the number of days a special government employee may serve each year.

"As my scheduled time as a Special Government Employee comes to an end, I would like to thank President @realDonaldTrump for the opportunity to reduce wasteful spending," Musk wrote on X. "The @DOGE mission will only strengthen over time as it becomes a way of life throughout the government."

Musk's "off-boarding will begin tonight," a White House official told Reuters on Wednesday. Under US law, special government employees in the executive branch are limited to serving 130 days in a 365-day period. They are subject to more lenient ethics rules than other federal employees and officials.
