Range Rover provided flights from Washington, DC, to London and accommodation so Ars could see the RR GT, as well as some other things you can read about in early September. Ars does not accept paid editorial content. WOLVERHAMPTON, England—One can argue about whether or not Range Rover invented the luxury SUV category, but there's no question that since the first Range Rover went on sale in 1970, the brand has made itself the standard that other luxury SUVs have to measure against. But what if

The Odyssey might be cleaning up at the box office at the moment, but in two weeks another mega-blockbuster hits theaters: Spider-Man: Brand New Day, directed by Destin Daniel Cretton (Shang-Chi and the Legend of the Ten Rings). Sony Pictures dropped one last trailer for this follow-up to 2021’s No Way Home, which is purportedly intended to launch a fresh trilogy of films with Tom Holland in the title role. No Way Home ended on a pretty bleak note, with Peter Parker (Holland) asking Doctor Stra

Federal officials on Monday reaffirmed that iceberg lettuce from Taylor Farms still appears to be the source of Cyclospora, the microscopic parasite behind a multi-state surge in explosive diarrhea cases. The assertion was intended to clear up confusion that began swirling over the weekend around a false positive test from the Food and Drug Administration—which Taylor Farms celebrated, sparking confusion. Still, many details of the outbreak remain murky, largely due to the vague recall informati

Nintendo urged a court to dismiss a lawsuit demanding that it pass tariff refunds on to customers, saying that people who bought a Switch console or other products have no legal right to refunds that Nintendo is due to receive from the government. Nintendo said in a motion to dismiss yesterday that plaintiffs are "ask[ing] this Court to invent a legal duty out of whole cloth to retroactively re-price completed sales simply because the legal landscape has changed."

Naked mole rats are weird. They spend their lives almost entirely underground, are largely insensitive to some kinds of pain, can persist without oxygen for a long time, rarely develop cancer, and can live past 30 years, which is decades longer than similarly sized rodents. They are also eusocial, like ants, bees, or termites—in a colony that can hold more than a hundred animals, only one female, the queen, breeds. We didn’t know how exactly naked mole-rat queens stop other females from breeding

We present RynnBrain 1.1, a family of embodied foundation models spanning 2B, 9B, and 122B-A10B scales. Trained with a unified spatio-temporal and physically grounded framework, RynnBrain 1.1 supports embodied perception, spatial reasoning, localization, and planning. Compared with RynnBrain 1.0, it further introduces contact-point prediction across the model family and native 3D grounding for the 2B and 9B models, yielding representations and outputs that are more directly aligned with robot ma

Video multimodal large language models (MLLMs) can describe what happens in a video, but rarely identify when the supporting evidence occurs. We study generalist video temporal grounding, in which one model predicts a variable-cardinality set of evidence intervals across video lengths, domains, query forms, and viewpoints. Existing training strategies are misaligned with this set-valued task: long-video labels often rely on brittle one-pass annotation, while reinforcement-learning rewards either

Training tool-use agents to improve from their own experience remains challenging, as supervised fine-tuning relies on fixed teacher-distilled trajectories, while sparse-reward reinforcement learning provides weak supervision for long-horizon interactions. We present DeepSearch-Evolve, a self-distillation framework for web agents built on DeepSearch-World, a deterministic and verifiable environment with reproducible search and page-reading tools. DeepSearch-World contains 420K multi-hop QA tasks

This paper introduces EvolvingWorld, a framework and benchmark for character and world co-evolution in interactive literary worlds. Existing systems either treat interactive literary simulation as static persona imitation or isolated scene generation, failing to capture how characters and worlds evolve together over time. To address this, EvolvingWorld models literary simulation as a long-horizon process where characters interact, scenes progress, and character and world states are persistently

Pruning long context for coding agents has been a vital technology for efficient context management. While existing context pruning methods such as SWE-Pruner realize this by attaching a separate code classifier, we find the agent itself encodes internal representations indicating the relevance of code context when reading tool output. Based on this finding, we propose SWE-Pruner Pro, which prunes tool outputs directly inside the agent. Concretely, a small head turns the agent's own internal rep
