"We have more people voting on the app than we do in many political elections taking place across the country," says the show's executive producer. Walls of cameras so millions of Americans can watch your spicy summer flings happen in real time? The app, where levels of viewer engagement are so high that it crashed during the first vote. Fans of the real-time dating show relish controlling the action through their in-app votes, helping decide who couples up and who gets dumped. Fan votes happen around five times during each season.

The Latin American nation is poised to swing right as nationalist lawyer and political novice Abelardo de la Espriella will succeed the country’s first leftist President, Gustavo Petro.

Unlike traditional benchmarks for scientific literature understanding and synthesis, SciArena engages the research community directly, following the Chatbot Arena evaluation approach of community voting on model comparisons. By leveraging collective intelligence, SciArena offers a community-driven evaluation of model performance on open-ended scientific tasks that demand literature-grounded, long-form responses. The platform currently supports 47 foundation models and has collected over 20,000 votes from human researchers across diverse scientific domains. Our analysis of the data collected so far confirms its high quality. We discuss the results and insights based on the model ranking leaderboard. To further promote research in building modelbased automated evaluation systems for literature tasks, we release SciArena-Eval, a meta-evaluation benchmark based on collected preference data. It measures the accuracy of models in judging answer quality by comparing their pairwise assessments with human votes. Our experiments highlight the benchmark's challenges and emphasize the need for more reliable automated evaluation methods.

We study fundamental connections between coalition formation games and clustering, illustrating the cross-disciplinary relevance of these concepts. We focus on graphical hedonic games where agents' preferences are compactly represented by a friendship graph and an enmity graph. In the context of clustering, friendship relations naturally align with data point similarities, whereas enmity corresponds to dissimilarities. We consider two stability notions based on single-agent deviations: local popularity and local stability.

Trump Risks Key Surveillance Authority Over'Unqualified' Spy-Chief Pick US lawmakers are alarmed that Bill Pulte, a housing official with no intelligence experience, is poised to take charge of one of the government's most powerful surveillance tools. A sweeping warrantless surveillance authority remains on track to expire Friday, with no clear path to a deal, after President Donald Trump refused this week to abandon his pick of housing official Bill Pulte to temporarily lead the US intelligence community--even tasking Pulte with gutting the Office of the Director of National Intelligence in a DOGE-style "downsizing" before a permanent director is named. In a Truth Social post after his second White House meeting in two days with House speaker Mike Johnson, Trump called Section 702 of the Foreign Intelligence Surveillance Act "very important to our military, and keeping the American people safe" and asked Congress for a short-term extension to give him time to find a permanent director of national intelligence. Section 702 lets the government collect the communications of foreign targets abroad without a warrant, sweeping in an unknown volume of Americans' messages that the FBI can later search. It faces a first-ever lapse in its legal authorization if Congress does not act by the end of Friday, June 12.

India's communists once ruled millions. For the first time since 1957, India no longer has a single communist-led state government. The defeat of the Communist Party of India (Marxist)-led Left Democratic Front (LDF) in Kerala this month, after a decade in power, marked the end - at least for now - of one of the world's most enduring experiments in democratic communism. At their peak, India's communist parties ruled states stretching from West Bengal to Kerala and Tripura. They impacted the lives of more than 100 million people through trade unions, peasant organisations, student wings and disciplined cadre networks.
