When a young man from California broadcast his death on X, profit-hungry traders piled into a cryptocurrency created in his image.

In October 2019, Amazon sued the Pentagon, alleging that President Donald Trump had blocked the company from securing a $10 billion cloud-computing contract because of his animus toward The Washington Post and its owner Jeff Bezos—whom the US president derided as “Jeff Bozo.”

At the time, the dispute was just one example of the near-constant skirmishes between Trump’s White House and corporate America. But the episode left an enduring mark on Bezos, the Amazon founder and the world’s second-richest person.

Over the past year, Bezos has executed a sharp public reversal in his relationship with Trump—whom he previously criticised as a “threat to democracy”—that has surprised even longtime associates and has stunned the Post’s newsroom.

A Norwegian man said he was horrified to discover that ChatGPT outputs had falsely accused him of murdering his own children.

According to a complaint filed Thursday by European Union digital rights advocates Noyb, Arve Hjalmar Holmen decided to see what information ChatGPT might provide if a user searched his name. He was shocked when ChatGPT responded with outputs falsely claiming that he was sentenced to 21 years in prison as "a convicted criminal who murdered two of his children and attempted to murder his third son," a Noyb press release said.

ChatGPT's "made-up horror story" not only hallucinated events that never happened, but it also mixed "clearly identifiable personal data"—such as the actual number and gender of Holmen's children and the name of his hometown—with the "fake information," Noyb's press release said.

As bird flu continues to rampage in dairy farms and poultry facilities around the country, the office tasked with coordinating the federal government's response to pandemic threats, including bird flu, has been sidelined by President Trump and sits nearly empty, according to CNN.

The White House Office of Pandemic Preparedness and Response Policy (OPPR)—established by a congressional statute in 2022 in response to failures during the COVID-19 pandemic—used to include a staff of around 20 people. Now, only one staffer remains, and it's unclear who they report to. The OPPR director has been moved to the National Security Council (NSC).

The report on the vacancies comes amid other moves that call into question the country's ability to respond to a pandemic threat under the Trump administration. The USDA has shifted its response to the ongoing bird flu outbreak away from the health threat. For instance, in late February, agriculture secretary Brooke Rollins touted a $1 billion effort to combat bird flu as a "strategy to deliver affordable eggs."

A new study examining meme creation found that AI-generated meme captions on existing famous meme images scored higher on average for humor, creativity, and "shareability" than those made by people. Even so, people still created the most exceptional individual examples.

The research, which will be presented at the 2025 International Conference on Intelligent User Interfaces, reveals a nuanced picture of how AI and humans perform differently in humor creation tasks. The results were surprising enough to have one expert declaring victory for the machines.

"I regret to announce that the meme Turing Test has been passed," wrote Wharton professor Ethan Mollick on Bluesky after reviewing the study results. Mollick studies AI academically, and he's referring to a famous test proposed by computing pioneer Alan Turing in 1950 that seeks to determine whether humans can distinguish between AI outputs and human-created content.

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy Spectroscopic Instrument (DESI)—namely that the dark energy, rather than being constant, might vary over time. Granted, those hints were still below the necessary threshold to claim discovery and hence fell under the rubric of "huge, if true."

But now we have more data from DESI, combined with other datasets, and those hints have gotten significantly stronger—so much so that Mustapha Ishak-Boushaki of the University of Texas at Dallas, who co-chairs one of the DESI working groups, said that "we are getting to the point of no return" for confirming dynamical dark energy. Ishak-Boushaki and several other DESI team members presented their results at the American Physical Society's Global Physics Summit today in Anaheim, California. Several relevant papers have also been posted to the physics arXiv.

Einstein’s cosmological constant (lambda) implied the existence of a repulsive form of gravity. (For a more in-depth discussion of the history of the cosmological constant and its significance for dark energy, see our 2024 story.) Quantum physics holds that even the emptiest vacuum is teeming with energy in the form of “virtual” particles that wink in and out of existence, flying apart and coming together in an intricate quantum dance. This roiling sea of virtual particles could give rise to dark energy, giving the Universe a little extra push so that it can continue accelerating. The problem is that the quantum vacuum contains too much energy: roughly 10120 times too much.

Ana de Armas stars as an assassin in training in From the World of John Wick: Ballerina.

Lionsgate dropped a new trailer for Ballerina—or, as the studio is now calling it, From the World of John Wick: Ballerina, because what every film needs is a needlessly clunky title. There's nothing clunky about this new trailer, however: It's the stylized, action-packed dose of pure adrenaline one would expect from the franchise, and it ends with Ana de Armas' titular ballerina facing off against none other than John Wick himself (Keanu Reeves).

(Spoilers for 2019's John Wick Chapter 3: Parabellum.)

Chronologically, Ballerina takes place during the events of John Wick Chapter 3: Parabellum. As previously reported, Parabellum found Wick declared excommunicado from the High Table for killing crime lord Santino D'Antonio on the grounds of the Continental. On the run with a bounty on his head, he makes his way to the headquarters of the Ruska Roma crime syndicate, led by the Director (Anjelica Huston). That's where we learned Wick was originally named Jardani Jovonovich and trained as an assassin with the syndicate. The Director also trains young girls to be ballerina-assassins, and one young ballerina (played by Unity Phelan) is shown rehearsing in the scene. That dancer, Eve Macarro, is the main character in Ballerina, now played by de Armas.

A United States District Court for the Northern District of California judge has signed off on a settlement agreement between HP and its customers, who sued the company for issuing firmware updates that prevented their printers from working with non-HP ink and toner.

In December 2020, Mobile Emergency Housing Corp. and a company called Performance Automotive & Tire Center filed a class-action complaint against HP [PDF], alleging that the company “wrongfully compels users of its printers to buy and use only HP ink and toner supplies by transmitting firmware updates without authorization to HP printers over the Internet that lock out its competitors’ ink and toner supply cartridges.” The complaint centered on a firmware update issued in November 2020; it sought a court ruling that HP’s actions broke the law, an injunction against the firmware updates, and monetary and punitive damages.

“HP’s firmware ‘updates’ act as malware—adding, deleting or altering code, diminishing the capabilities of HP printers, and rendering the competitors’ supply cartridges incompatible with HP printers,” the 2020 complaint reads.

Human speech arises courtesy of some significant neural horsepower. Different areas of the brain are involved in determining the meaning that's desired, finding the words to express it, and then converting those words to a specific series of sounds—and all that comes before the correct sequence of nerve impulses is sent to the muscles that produce the final output. Humans are far from alone in the animal kingdom with an impressive range of vocalizations, though. That raises the prospect that we can understand a bit more about our own speech by studying how vocalization is managed in different animals.

One group of species that's especially interesting is birds. They're distant relatives compared to other animals with interesting vocal capabilities, like whales and elephants, and their brains have some notable differences from ours. They also show a range of behaviors, from complex songs to vocal mimicry to whatever it is that you want to call what parrots do. Thanks to a newly released study, however, we now have evidence that these different types of vocalization are the product of different control systems in the brain.

The study relied on electrodes placed in the brains of parrots and songbirds and tracked the behavior of neurons in a region that controls vocalization. It showed that the two relied on different types of control, with parrots having a system that operates similarly to the one used by humans.
