Lee Butler, 36, was last spotted at his Staffordshire home on Tuesday, 26 May. His loved ones reported him as a missing person when they became concerned for his welfare.
Milky Way black hole's missing wind finally found after a half-century-long search
Milky Way black hole's missing wind finally found after a half-century-long search Sadie Harley Scientific Editor Robert Egan Associate Editor After more than 50 years of searching, astrophysicists at Northwestern University have finally discovered evidence of a powerful wind blowing from the Milky Way's central supermassive black hole, Sagittarius A* (Sgr A*). According to theoretical physics and a long-accepted understanding of galaxies' evolution, as black holes consume materials, they...
'The Heaven Sword' crowned as East Asia's tallest tree after a nearly decade-long search
'The Heaven Sword' crowned as East Asia's tallest tree after a nearly decade-long search Sadie Harley Scientific Editor Robert Egan Associate Editor Taiwan, historically known as Formosa, holds a secret deep within its rugged interior: it is one of the rare locations on Earth capable of supporting "giant" trees—specimens that tower over 80 meters in height. Since 2014, a dedicated group, the "Taiwan tree seekers," has been on a mission to locate and document these sky-piercing giants. The...
Segment-level Tree Search for Long Meeting Document Summarization
Announce Type: new Abstract: Meeting documents are challenging to summarize due to their length and complex conversational structure. Existing approaches typically adopt multi-stage pipelines that extract information prior to summarization; however, these approaches often suffer from cumulative error propagation without intermediate validation, a limitation further amplified by short and low-quality reference summaries. We propose segment-level summarization via Monte Carlo Tree Search (S3),...
LongTraceRL: Learning Long-Context Reasoning from Search Agent Trajectories with Rubric Rewards
Announce Type: new Abstract: Long-context reasoning remains a central challenge for large language models, which often fail to locate and integrate key information in extensive distracting content. Reinforcement learning with verifiable rewards (RLVR) has shown promise for this task, yet existing methods are limited by low-confusability distractors and sparse, outcome-only reward signals that cannot supervise intermediate reasoning steps. To address these issues, we introduce...
Ecuador’s disappeared: Inside one family’s search for answers
Not long ago, Ecuador was one of the safest countries in Latin America. Now, it is one of the deadliest. Violent drug cartels have arrived from around the world — from Mexico to the Balkans — to secure cocaine trafficking routes to the coast.
Two-Fidelity Best-Action Identification for Stochastic Minimax Tree
Announce Type: new Abstract: We study fixed-confidence best-action identification (BAI) in stochastic minimax trees. This problem is increasingly relevant in modern AI planning, where deep minimax search and Monte Carlo Tree Search (MCTS) with language model long rollouts face a fundamental tradeoff: heuristic evaluations are cheap but biased, while accurate rollouts are reliable but prohibitively expensive. We propose 2FFS, a two-fidelity tree-search algorithm that brings multi-fidelity...
DiBS: Diffusion-Informed Branch Selection
arXiv:2606.06518v1 Announce Type: new Abstract: Sudoku is a representative constraint satisfaction problem that requires global structural reasoning under strict discrete constraints. The existing works of solving Sudoku mainly focus on two dominant approaches, i.e., traditional heuristic and deep learning solver. However, they suffer from two complementary limitations: learning-based solvers lack hard correctness guarantees, while complete symbolic solvers are still prone to long-tail search.
Cold case of missing news anchor rocked by claim of confession in roadside meltdown: report
A private investigator has reportedly identified a possible suspect in the three-decades-old mystery surrounding the cold-case disappearance of an Iowa news anchor. The case began in the early-morning hours of June 27, 1995, when Jodi Huisentruit did not show up to work to anchor the local morning news in Mason City, Iowa. Her disappearance sparked a three-decades-long search by authorities that prompted multiple theories surrounding the case, though her body has never been recovered and no...
