Eraser Director Explains How Mission: Impossible Triggered a Rewrite

Eraser Director Explains How Mission: Impossible Triggered a Rewrite

Published by Daniella Wilson

Eraser director Chuck Russell had a major problem on the 1995 set of his Arnold Schwarzenegger-led actioner. He and his team caught wind of the fact that their third-act set piece had just been pulled off by Tom Cruise and Brian De Palma on the recently wrapped Mission: Impossible. With Eraser scheduled to release a month after the first installment in Cruise’s now-signature action franchise, Russell and co. pivoted on the fly.  “The heist scene where Tom Cruise drops in on wires, I had Arnold doing almost exactly the same thing to get a disc out of the CIA, and we had to rewrite it to instead have Arnold get into the enemy company, Cyrez, another way,” Russell tells The Hollywood Reporter in support of Eraser’s 30th anniversary 4K release. “I at least changed that much. I didn’t want to have exactly the same scene.” Written by Tony Puryear and Walon Green, Eraser chronicles Schwarzenegger’s U.S. Marshal character, John “Eraser” Kruger, who serves as the last line of defense for witnesses who’ve been compromised while in …

Researchers introduce Self-Harness, a framework that lets AI agents rewrite their own rules, boosting performance up to 60%

Researchers introduce Self-Harness, a framework that lets AI agents rewrite their own rules, boosting performance up to 60%

Not every company can or should build their own frontier AI language model. However, the harness controlling the model is something that most enterprises can and should customize for their specific purposes. Of course, this is easier said than done. Agent harnesses are still largely tuned through manual, ad hoc debugging — a process that relies heavily on intuition rather than systematic feedback loops, making it difficult to keep pace with rapidly evolving LLMs. To solve this challenge, researchers at the Shanghai Artificial Intelligence Laboratory have introduced “Self-Harness,” a new paradigm in which an LLM-based agent systematically improves its own operating rules. By examining its own execution traces to apply edits, the system trades manual guesswork for empirical evidence. Self-improving harnesses can enable development teams to deploy robust custom agents that continually adapt their own execution protocols to overcome model-specific weaknesses. The challenge of harness engineering An LLM-based agent’s performance is not determined solely by its underlying base model, but also by its harness: the surrounding system that provides context and enables the model to …

Ancient crocodile-like predators rewrite current knowledge of how animals adapted to the land

Ancient crocodile-like predators rewrite current knowledge of how animals adapted to the land

The first four-legged vertebrates did not grow up like tadpoles after all. That idea has shaped the story of life on land for decades. Early tetrapods, the ancient animals that gave rise to mammals, birds, reptiles, and amphibians, were widely thought to begin life much like modern amphibians. They were believed to hatch into a larval stage and later transform into adult bodies through metamorphosis. But newly described fossils of baby tetrapods suggest that picture is wrong. Writing in Science, researchers report that some of the earliest known hatchlings from the fish-to-tetrapod transition lacked the hallmark features of amphibian larvae, especially external gills. Instead of passing through a frog-like tadpole stage, these animals appear to have developed more directly. “When a lot of us were in high school, we were taught this simplified story of evolution: that some fish evolved into amphibians, and some of those amphibians evolved into reptiles, and some of those reptiles evolved into mammals. And our study shows that this basic underlying premise, that the first four-legged vertebrates grew up like …

Remarkable fossils rewrite the story of how animals conquered the land

A fossil baby embolomere from Mazon Creek, Illinois Arjan Mann A set of exquisitely preserved 300-million-year-old fossils suggests that early four-limbed vertebrates did not undergo a metamorphosis between their juvenile and adult stages, challenging conventional ideas about the evolution of life on land. “We have for a very long time assumed that these animals were broadly amphibian-like, and that this life cycle would have bridged the gap between life in the water and life on land,” says Jason Pardo at the Field Museum of Natural History in Chicago. Today’s reptiles, birds, mammals and amphibians belong to a group called tetrapods, which evolved from lobe-finned fish around 390 million years ago. But almost nothing was known about the early developmental stages of these ancestral lobe-finned fish, says John Long at Flinders University in Adelaide, Australia. Pardo and his colleague Arjan Mann, also at the Field Museum, examined a collection of fossils that were unearthed between the 1960s and 1990s at the Mazon Creek fossil site, south-west of Chicago. The preserved animals lived 307 million to 309 …

The extensive collection, with some pieces dating back over two centuries, was produced by J&D Paton, a leading tartan manufacturer throughout the 19th and 20th centuries. Stuart Paton, the great-great grandson of the firm’s founder, has donated the fabrics to National Museums Scotland (NMS). Among the items are fabrics made for Queen Victoria and the royal family during the 19th-century Highland revival, military tartans supplied to Scottish regiments, and previously unrecorded clan designs. There are also rare examples woven for women’s fashion. Experts suggest that the collection, which chronicles the company’s history from its 1820s foundation to its closure in the 1960s, could …

Frontier AI models don’t just delete document content — they rewrite it, and the errors are nearly impossible to catch

Frontier AI models don’t just delete document content — they rewrite it, and the errors are nearly impossible to catch

Published by skeptic

As large language models become more capable, users are tempted to delegate knowledge tasks where models process documents on their behalf and provide the finished results. But how far can you trust the model to stay faithful to the content of your documents when it has to iterate over them across multiple rounds? A new study by researchers at Microsoft shows that large language models silently corrupt documents that they work on by introducing errors. The researchers developed a benchmark that simulates multi-step autonomous workflows across 52 professional domains, using a method that automatically measures how much content degrades over time. Their findings show that even top-tier frontier models corrupt an average of 25% of document content by the end of these workflows. And providing models with agentic tools or realistic distractor documents actually worsens their performance. This serves as a warning that while there is increasing pressure to automate knowledge work, current language models are not fully reliable for these tasks. The mechanics of delegated work The Microsoft study focuses on “delegated work,” an …

Physicists rewrite Einstein’s equations to define spacetime evolution

Physicists rewrite Einstein’s equations to define spacetime evolution

Published by Jenni Sidey

Spacetime is often described as the stage on which the universe unfolds, a four-dimensional blend of space and time that bends, stretches and shifts as matter and energy move through it. However, despite more than a century of work since Einstein introduced general relativity, physicists still struggle to describe how that stage evolves when gravity becomes violent, nonlinear and hard to predict. A new theoretical study points to a different way of looking at the problem. Instead of treating spacetime only as geometry, researchers found that some of its structures may behave more like features in an electrically conducting fluid. In this view, these structures stay connected as spacetime changes. That idea comes from researchers at Adolfo Ibáñez University in Chile and Columbia University, whose work was published in Physical Review Letters. Using tools borrowed from electrodynamics and plasma physics, they argue that spacetime can contain what they call gravitational field connections. Additionally, they describe conserved quantities that place topological limits on how curved spacetime can evolve. In plain terms, topology deals with what stays …

Poland’s president plans constitution rewrite – POLITICO

Poland’s president plans constitution rewrite – POLITICO

Published by Sam Flores

Poland’s nationalist President Karol Nawrocki on Sunday appointed a council to rewrite the country’s constitution. The members announced for the council include several figures associated with the Law and Justice (PiS) party. While all parliamentary groups are invited to take part, it is unclear if they will do so. Nawrocki announced his plans to review the constitution on Friday, drawing criticism from Prime Minister Donald Tusk on social media. Before working on a new constitution, “I suggest starting with abiding by the current one,” Tusk wrote in response to Friday’s announcement. The appointment of key council positions on Sunday was symbolic, as May 3 is Poland’s Constitution Day. In a social media post to mark the occasion, Tusk wrote: “Only those nations that respect their constitutions stand a chance of victory.” The Council for the New Constitution has until the end of Nawrocki’s current term, which runs until 2030, to come up with an alternative draft of the constitution.

The Triumphant New LACMA Has the Potential to Rewrite Art History

The Triumphant New LACMA Has the Potential to Rewrite Art History

Published by José Betancourt

Can an art museum tell a non-linear version of art history and still be legible to its visitors? That’s the question guiding the David Geffen Galleries, the new building for the Los Angeles County Museum of Art that opens to members on April 19 and to the public on May 4. Typically, museums narrate millennia of artistic expression as a series of progressive movements limited to the US and Europe, with everything else pushed to the margins. LACMA has historically been one of those museums, with one of the buildings it tore down to make way for the Geffen Galleries being devoted primarily to art of the Americas.   Related Articles Now, with other institutions embracing a more global art history that emphasizes plurality, here comes the new LACMA, where artworks made across multiple centuries press up against each other, as do pieces made within in the same decade but in drastically different geographical contexts. It’s a triumph. The plan to rethink LACMA’s entire campus has been in the works for 25 years, starting with …

New framework lets AI agents rewrite their own skills without retraining the underlying model

New framework lets AI agents rewrite their own skills without retraining the underlying model

Published by skeptic

One major challenge in deploying autonomous agents is building systems that can adapt to changes in their environments without the need to retrain the underlying large language models (LLMs). Memento-Skills, a new framework developed by researchers at multiple universities, addresses this bottleneck by giving agents the ability to develop their skills by themselves. “It adds its continual learning capability to the existing offering in the current market, such as OpenClaw and Claude Code,” Jun Wang, co-author of the paper, told VentureBeat. Memento-Skills acts as an evolving external memory, allowing the system to progressively improve its capabilities without modifying the underlying model. The framework provides a set of skills that can be updated and expanded as the agent receives feedback from its environment. For enterprise teams running agents in production, that matters. The alternative — fine-tuning model weights or manually building skills — carries significant operational overhead and data requirements. Memento-Skills sidesteps both. The challenges of building self-evolving agents Self-evolving agents are crucial because they overcome the limitations of frozen language models. Once a model is …
