Ten months ago, in a moment of digital deja vu, MetaMask teased the world with the promise of Bitcoin, only to keep us waiting like a child counting down to Christmas. 🎄 But here we are, with Bitcoin now joining the ranks of supported assets from the Ethereum, Solana, Monad, and Sei blockchains in a blockchain tango. 💃🕺
![The study of the XXZ model, incorporating a localized defect as described by $Eq. (11)$, reveals how spectral statistics-specifically the mean level spacing ratio $\langle\tilde{r}\rangle$ computed for a system of $L=18$-and local dynamical probes, such as averaged subsystem state purity $\overline{\mathcal{P}}$ [Eq. (6)] and the averaged Choi echo $\langle\text{Tr}[\mathcal{D}(t)^{2}]\rangle\_{\mathrm{Haar},t}$ [Eq. (8)], demonstrate a clear sensitivity to parameter variations $J_{xy}/J_{z}$ and $\varepsilon/J_{z}$, and explicitly break spatial reflection symmetry through defect placement.](https://arxiv.org/html/2512.11030v1/x4.png)
Researchers have developed a novel metric, the ‘Choi echo,’ to quantify how easily quantum dynamics can be reversed, offering new insights into the interplay of decoherence and chaos.
The potential for real-world consequences is what makes these games so captivating, but also surprisingly insightful – and sometimes a little unsettling.
Man, 2025 was HUGE for Team Cherry! Everyone was waiting for Hollow Knight: Silksong, and it totally lived up to the hype. Seriously, the game almost broke the internet when it launched – servers were crashing everywhere as we all rushed to get it. But it wasn’t just a flash in the pan; Hollow Knight: Silksong kept getting amazing reviews and awards all year long. It even got five nominations at The Game Awards, including Game of the Year! While it didn’t win the big one, it did take home Best Action Adventure Game, which was awesome. Now, everyone’s been wondering what Team Cherry would do next – would they start a new project or keep adding to Hollow Knight: Silksong? Well, we finally have our answer, and I’m excited to see what they announce!
I’ve been following ARC Raiders and it’s interesting – some people really like it as it is, with both player-versus-environment and player-versus-player elements. But a lot of us are hoping for a mode where you can just focus on the environment and team up without worrying about other players. It’s been the most requested feature since the game came out, and honestly, I think it’s because the game world is so engaging! If ARC Raiders didn’t pull you in so much, I doubt we’d be asking for a purely cooperative experience as strongly – or even at all.
Megabonk offers a lot of unlockable characters and weapons, and players were excited to see what the developers at Vedinad would add next.

Hollow Knight, initially funded through Kickstarter and released in 2017, quickly became a beloved indie hit. Players take on the role of a silent knight, battling challenging bosses and venturing through the insect-ridden kingdom of Hallownest. Praised for its stunning art style and demanding gameplay, it’s considered one of the most successful independent games of the last decade. Its sequel, Hollow Knight: Silksong, launched in 2025 to critical acclaim and numerous awards, including several Game of the Year nominations. Now, Team Cherry is bringing both games to the new Nintendo Switch 2 console.
Rodriguez and his chum William Lonergan Hill, both of whom seem to have landed themselves in a spot of bother over their crypto mixing protocol, were handed sentences of five and four years respectively. Quite the holiday camp, what? 🏖️⚖️
A new systematic evaluation reveals that the ‘best’ multi-party computation protocol depends heavily on the specifics of your application and network.
