Brazil's Mega-Sena lottery held contest 3068, and players in Mato Grosso do Sul had notable luck at the lower prize tiers. Campo Grande News reports that 103 bets from the state matched four numbers, the quadra, splitting R$ 91 thousand in prizes. Lottery results routinely draw heavy search interest in Brazil, especially when local winners are involved.

Brazil's Quina lottery held contest 7137, and attention turned to the results after five bets placed in Paraná matched four numbers (the quadra), each taking home a share of the secondary prizes. Lottery players across the country are checking the drawn numbers and prize breakdown, with local outlets reporting on the Paraná winners and whether anyone claimed the jackpot.

A new paper posted on arXiv claims subquadratic algorithms for the 3SUM problem and subcubic algorithms for all-pairs shortest paths, two of the most studied problems in theoretical computer science. If verified, the results would mark a significant breakthrough on longstanding open questions in fine-grained complexity, and researchers are examining the proofs closely.

Isles Bun & Coffee in Uptown Minneapolis is being celebrated for its cinnamon buns, described by one food lover as the best 'in this quadrant of the galaxy'. The bakery remains a fixture of the neighborhood, with locals and visitors urging that no trip to Uptown is complete without a stop there for the long-running treat.

A new paper on arXiv reports progress on two landmark problems in theoretical computer science: 3SUM, where the authors claim a subquadratic-time algorithm, and all-pairs shortest paths (APSP), with a claimed subcubic-time algorithm. Both problems have long-standing conjectures asserting such speedups are impossible, so if the results hold up they would overturn widely believed hardness assumptions. The work is drawing early attention from algorithm researchers discussing its validity.

A new paper on arXiv claims subquadratic algorithms for the 3SUM problem and subcubic algorithms for all-pairs shortest paths, two of the most studied open problems in theoretical computer science. If verified, the results would break long-standing barriers that many researchers believed were optimal, making the claim a major talking point among algorithm experts.
