Predicting Power Grid Failures with AI
![A novel contingency screening framework leverages conditional graph diffusion to efficiently identify high-risk [latex]N-k-k[/latex] outage scenarios in power networks by directly sampling from the severity distribution and utilizing a topology-aware EVGNN-trained on base-case and [latex]N-1[/latex] data-as a fast risk surrogate, thereby circumventing the computational intractability of exhaustive contingency analysis caused by combinatorial growth and eliminating the need for iterative AC power-flow simulations.](https://arxiv.org/html/2602.09461v1/x1.png)
A new approach leverages diffusion models to rapidly identify critical vulnerabilities in power systems before they escalate into widespread outages.

As Ethereum languidly loses its upward momentum, one cannot help but notice the on-chain data-those enigmatic signals of the digital realm-flashing with a caution that would cause even the most audacious speculator to pause in bewilderment. It seems our short-term ETH holders have taken to exhibiting behavior that could only be described as woefully bearish.

I was so incredibly saddened to hear the news. James Van Der Beek’s wife, Kimberly, shared on Instagram that he’s passed away after a brave fight with stage 3 colorectal cancer. He was diagnosed back in August 2023, and while he kept it private for a while, he eventually shared the news with everyone in November 2024. It’s just heartbreaking.

Fans around the world can tune in to the Evangelion 30+ celebration starting February 21st. The event kicks off with a special presentation featuring the original voice actors, creator Hideaki Anno, and singer Yoko Takahashi. Following that will be a concert called Back to Neon Genesis EVA Fes Ver., bringing classic music from the anime to life. Over the following days, the anniversary event will also livestream a live-action Kabuki performance and other content – all for free. However, one particular project won’t be available to viewers outside of Japan.

James Van Der Beek publicly shared his battle with colorectal cancer. He announced his diagnosis in November 2024, expressing a positive outlook and saying he was feeling well. Though his health prevented him from attending a Dawson’s Creek reunion in September 2025, he continued to report feeling good. Van Der Beek was surprised to learn he had stage-three cancer, as he hadn’t experienced any symptoms. In a December 2025 interview with Today, he emphasized the importance of getting regular screenings, saying, “If anybody takes anything away from this interview, it would be get tested.”

In 2024, the actor publicly shared that he had been diagnosed with colorectal cancer the previous year. As medical bills piled up, he began selling items from his career – including costumes and props from his films and TV shows – in late 2025 to help cover the cost of his treatment, just three months before he passed away.

I’m really excited about this new superhero movie! The lead actor is Taylor Lautner – I remember him as Jacob Black from the Twilight Saga movies, but I was surprised to learn he actually started out as Sharkboy in The Adventures of Sharkboy and Lavagirl way back in 2005! It’s cool to see how far he’s come.

The critically praised sci-fi Western series, which debuted on Prime Video in 2022, stars Josh Brolin as Royal Abbot, a Wyoming rancher. Abbot is caught in a feud with a competing ranching family, the Tillersons, but his problems take a strange turn when a puzzling black hole appears on his land, and a mysterious stranger shows up at his ranch.

Robert Downey Jr. has had a remarkably diverse career, long before becoming famous as Iron Man. Early on, he played Charlie Chaplin in a serious biographical film and collaborated with acclaimed directors like Robert Altman and Oliver Stone. He’s shared the screen with a wide range of actors, from the esteemed Ian McKellan to the comedic Rodney Dangerfield. Even after initially stepping away from Marvel, he continued to take on significant roles, culminating in an Academy Award-winning performance in Christopher Nolan’s Oppenheimer.
According to the cryptic wizards over at Santiment, these Ethereum addresses with more than 1,000 ETH have been on a selling spree since Christmas. Who knew Santa’s elves were actually crypto traders? The key indicator here is the “Supply Distribution,” which tells us how much of this digital gold the whales are hoarding-or not hoarding, as it would seem.
