Epstein's shadow: Why Bill Gates pulled out of Modi's AI summit Microsoft founder Bill Gates has cancelled his keynote speech at India's flagship AI summit just hours before he was due to take the stage on Thursday. Gates, who has faced renewed scrutiny over his past ties to the late sex offender Jeffrey Epstein, withdrew to "ensure the focus remains on the AI Summit's key priorities", the Gates Foundation said in a statement. India's Prime Minister Narendra Modi had billed the summit as an opportunity for India to shape the future of AI, drawing high-profile attendees, including French President Emmanuel Macron and Brazilian President Luiz Inacio Lula da Silva. Instead, it has been dogged by controversy, from Gates's abrupt exit to an incident in which an Indian university tried to pass off a Chinese-made robotic dog as its own innovation. So, what exactly went wrong at India's flagship AI gathering and why has it drawn such intense scrutiny?

Kleber Mendonça Filho wants his films to reclaim lost history. For Kleber Mendonça Filho, filmmaking is an act of both provocation and preservation. Mendonça was born in 1968, in the early years of a ruthless military dictatorship--a time when cinema, like much else, was harshly constrained. His mother, Joselice Jucá, was a historian who studied Brazil's abolitionist movement, and she taught him that filling gaps in the cultural memory was a way to expose concealed truths. His relationship with film is inextricably linked with his home town, Recife--a port city where attractive beaches and high-rise developments coexist with sprawling favelas and rampant crime. In his youth, Mendonça was fascinated by the city's grand cinema palaces. He carried a Super 8 camera to the tops of marquees and shot dizzying images; he spent hours in projection booths, learning the mechanics of how films reached the screen. Over time, Mendonça watched those theatres fall into decline, an experience that he likened to being aboard a ship as it wrecked. But even as Recife lost its allure, he made the city a fixture of his films--a way of vindicating its place in history. His first narrative feature, "Neighboring Sounds," takes place on a street where he lived as a child, a setting that he spent years documenting. Later, he made "Pictures of Ghosts," a documentary about Recife told largely through its cinemas.

Leaders at Mira Murati's startup believe Barret Zoph engaged in an incident of "serious misconduct." The details are now coming to light. Leaders at Mira Murati's Thinking Machines Lab confronted the startup's cofounder and former CTO, Barret Zoph, over an alleged relationship with another employee last summer, WIRED has learned. That relationship was likely the alleged "misconduct" that has been mentioned in prior reporting, including by WIRED . To protect the privacy of the individuals involved, WIRED is not naming the employee in question.

The news is a blow for Thinking Machines Lab. Two narratives are already emerging about what happened. Thinking Machines cofounders Barret Zoph and Luke Metz are leaving the fledgling AI lab and rejoining OpenAI, the ChatGPT-maker announced on Thursday. OpenAI's CEO of applications, Fidji Simo, shared the news in a memo to staff Thursday afternoon. The news was first reported on X by technology reporter Kylie Robison, who wrote that Zoph was fired for "unethical conduct."

A unique mating call led biologists to this newly discovered pint-sized amphibian. 'Brachycephalus lulai' is a tiny pumpkin toadlet measuring less than 14 millimeters in length. It is sitting on a pencil tip for scale. Breakthroughs, discoveries, and DIY tips sent every weekday. A new pumpkin toadlet species was recently discovered in the mountains of southern Brazil. is just over one centimeter (only 0.39 inches) long and the size of a pencil tip.

The worlds people have strong opinions about artificial intelligence (AI), and they want policymakers to listen. Governments are inviting public comment on AI, but as they translate input into policy, much of what citizens say is lost. Policymakers are missing a critical opportunity to build trust in AI and its governance. This paper compares three countries, Australia, Colombia, and the United States, that invited citizens to comment on AI risks and policies. Using a landscape analysis, the authors examined how each government solicited feedback and whether that input shaped governance. Yet in none of the three cases did citizens and policymakers establish a meaningful dialogue. Governments did little to attract diverse voices or publicize calls for comment, leaving most citizens unaware or unprepared to respond. In each nation, fewer than one percent of the population participated. Moreover, officials showed limited responsiveness to the feedback they received, failing to create an effective feedback loop. The study finds a persistent gap between the promise and practice of participatory AI governance. The authors conclude that current approaches are unlikely to build trust or legitimacy in AI because policymakers are not adequately listening or responding to public concerns. They offer eight recommendations: promote AI literacy; monitor public feedback; broaden outreach; hold regular online forums; use innovative engagement methods; include underrepresented groups; respond publicly to input; and make participation easier.

Retrieval-Augmented Generation (RAG) systems in the legal domain face a critical challenge: standard, flat-text retrieval is blind to the hierarchical, diachronic, and causal structure of law, leading to anachronistic and unreliable answers. This paper introduces the Structure-Aware Temporal Graph RAG (SAT-Graph RAG), an ontology-driven framework designed to overcome these limitations by explicitly modeling the formal structure and diachronic nature of legal norms. We ground our knowledge graph in a formal, LRMoo-inspired model that distinguishes abstract legal Works from their versioned Expressions. We model temporal states as efficient aggregations that reuse the versioned expressions (CTVs) of unchanged components, and we reify legislative events as first-class Action nodes to make causality explicit and queryable. This structured backbone enables a unified, planner-guided query strategy that applies explicit policies to deterministically resolve complex requests for (i) point-in-time retrieval, (ii) hierarchical impact analysis, and (iii) auditable provenance reconstruction. Through a case study on the Brazilian Constitution, we demonstrate how this approach provides a verifiable, temporally-correct substrate for LLMs, enabling higher-order analytical capabilities while drastically reducing the risk of factual errors. The result is a practical framework for building more trustworthy and explainable legal AI systems.

Colombia has been submerged in decades of armed conflict, yet until recently, the systematic documentation of violence was not a priority for the Colombian government. This has resulted in a lack of publicly available conflict information and, consequently, a lack of historical accounts. This study contributes to Colombia's historical memory by utilizing GPT, a large language model (LLM), to read and answer questions about over 200,000 violence-related newspaper articles in Spanish. We use the resulting dataset to conduct both descriptive analysis and a study of the relationship between violence and the eradication of coca crops, offering an example of policy analyses that such data can support. Our study demonstrates how LLMs have opened new research opportunities by enabling examinations of large text corpora at a previously infeasible depth.

Breakthroughs, discoveries, and DIY tips sent every weekday. The yearslong international fight to lay claim to the suspected "world's richest shipwreck" likely won't end anytime soon, especially after a research team's most recent conclusions. Experts have confirmed that dozens of gold coins scattered across the ocean floor off the coast of Colombia belonged to the San José, an ill-fated Spanish treasure galleon that sank over 300 years ago during a battle with British warships. The findings were published on June 10 in the journal Antiquity. In June 1708, the San José and a fleet of 17 other vessels departed the capital of Colombia for Europe laden with gold, silver, and uncut gems.

In the days ahead of the proposed truce, Moscow and Kyiv exchanged a barrage of strikes. Flights at airports across Russia were cancelled and some 60,000 passengers left stranded in the wake of Ukrainian drone attacks. Heavy restrictions are in place in the centre of Moscow as Russia prepares to mark the Soviet Union's victory over Nazi Germany. Russia says 27 world leaders are attending the event, with thousands of troops marching on Red Square ahead of a parade of some of Russia's latest weaponry. Brazil's Luiz Inácio Lula da Silva and Venezuelan President Nicolas Maduro are among the assembled guests, along with Serbian President Aleksandar Vucic and Robert Fico, Slovakia's prime minister who is the only European Union leader to travel to Moscow. Ukraine's Volodymyr Zelensky had earlier warned that he could not guarantee the safety of anyone attending the event and has urged heads of state not to travel to Moscow.
