 | Mathematical analysis demonstrates that the universe cannot be a computer simulation. The fundamental nature of reality requires non-algorithmic understanding, as shown using theorems like Gödel’s incompleteness theorem. Since computation alone cannot fully describe all aspects of reality, no simulation—being inherently algorithmic—can replicate the universe. |

 | Abandoned coal mines release significant amounts of CO2 through acidic drainage that dissolves carbonate rocks, liberating ancient carbon. Emissions from mine drainage can rival those of small power plants, yet the full scale remains uncertain due to poor mine documentation. Improved measurement and remediation could help limit this overlooked source of atmospheric CO2. |

 | Genomic analysis of 156 ancient individuals shows that Carpathian Basin Sarmatians descended from steppe Sarmatians originating in the Ural and Kazakhstan regions, with Romanian Sarmatians as a genetic bridge. A male-driven founder effect is evident, with Y-chromosome haplogroup R1a spreading westward, while maternal ancestry is mainly local European. Steppe ancestry declined over time due to admixture with local populations. |

 | A newly discovered fossil crocodile, Wadisuchus kassabi, from Egypt's Western Desert represents the earliest known member of Dyrosauridae, dating to about 80 million years ago. Its anatomical features indicate early adaptations for marine life and suggest that dyrosaurids originated and diversified in Africa earlier than previously recognized, revising the timeline and location of their evolutionary history. |

 | Analysis of the "Dueling Dinosaurs" fossil confirms Nanotyrannus lancensis as a distinct, fully mature species rather than a juvenile Tyrannosaurus rex. Growth ring and anatomical data show clear developmental differences incompatible with T. rex. This finding increases recognized tyrannosaur diversity in late Cretaceous ecosystems and identifies a new species, N. lethaeus. |

 | The "dairy barn of the future" concept integrates cow-calf contact, year-round indoor-outdoor access, automated milking and feeding, and a visitor corridor to enhance animal welfare, data collection, and transparency. Digital simulation confirms feasibility, and the planned facility aims to support long-term studies on welfare, efficiency, and biosecurity. |

 | Poverty Point was constructed by egalitarian hunter-gatherers as a temporary gathering site for trade, socializing, rituals, and spiritual offerings, rather than as a permanent settlement ruled by a chiefdom. The earthworks likely served as cooperative religious monuments intended to address environmental uncertainties, with no evidence of long-term habitation or hierarchical society. |

 | Integration of artificial intelligence with molecular biology identified a 53-gene signature distinguishing inflammatory from tissue-healing macrophages in the gut. The NOD2 gene, when mutated, disrupts its interaction with girdin, leading to macrophage imbalance and chronic inflammation in Crohn's disease. Restoring this interaction may offer new therapeutic strategies. |

 | Idiopathic hypersomnia causes persistent, nonrestorative sleepiness, leaving individuals never fully awake and often experiencing automatic behaviors and limited physical energy. The disorder significantly impairs relationships, daily functioning, and mental health. Patient-reported experiences highlight the need for improved clinical care, targeted therapies, and greater awareness. |

 | Six-million-year-old ice from Antarctica’s Allan Hills contains the oldest directly dated air and ice samples, offering unique insights into past climates with warmer temperatures and higher sea levels. Oxygen isotope analysis shows Antarctica cooled by about 12 °C over this period. These findings extend the ice core climate record far beyond previous limits, enabling direct study of ancient atmospheric conditions. |

 | Analysis of Palomar Observatory photographs from 1949–1957 identified transient sky objects whose occurrences strongly correlated with nuclear weapons tests and UAP reports. Transients were 45% more likely within a day of a nuclear test, and their frequency rose 8.5% per additional UAP sighting. The findings suggest a link between these phenomena and nuclear activity, narrowing possible explanations. |

 | A previously unrecognized hub in the brain's lymphatic drainage system, the middle meningeal artery (MMA), has been identified as a pathway for passive cerebrospinal fluid flow, indicating its role in waste clearance. High-resolution imaging confirmed the presence of lymphatic vessels around the MMA, suggesting implications for understanding and treating neurological and psychiatric disorders. |

 | Six previously unrecognized tube-nosed bat species (genus Murina) have been identified in the Philippines through morphological and genetic analyses. This discovery increases the known bat diversity in the region and highlights the Philippines as a hotspot for unique mammalian fauna. The findings underscore the importance of continued biodiversity research and conservation in forested habitats. |

 | Between 2008 and 2010, the average number of close social contacts increased from about two to four or five, coinciding with a marked rise in societal polarization. Analysis of extensive survey data and mathematical modeling indicate that as social network density surpasses a critical threshold—estimated between three and four close relationships—polarization intensifies sharply, resembling a phase transition. This shift, likely influenced by the proliferation of smartphones and social media, leads to more tightly-knit, ideologically uniform groups with fewer connections between them, reducing societal tolerance and potentially undermining democratic processes. |

 | A new low-frequency radio image of the Milky Way offers twice the resolution, ten times the sensitivity, and double the sky coverage of previous maps, cataloguing 98,000 radio sources. This image enables detailed study of star formation, supernova remnants, and pulsars, providing unprecedented insight into the galaxy’s structure and stellar evolution. |

 | Interstellar comet 3I/ATLAS exhibited an unprecedented and rapid brightening as it neared perihelion, with a blue hue indicating strong gas emissions, likely from molecules such as carbon. Its unusual activity may be due to a unique composition, including higher CO2 and volatile ices, distinguishing it from typical solar system comets. The exact cause remains uncertain. |

 | DNA from a Neanderthal bone fragment at Crimea’s Starosele site, dated to about 45,900–45,300 years ago, confirms genetic links between European and Siberian Neanderthals. Most animal bones at the site are horse, indicating a primary food source. Habitat modeling suggests a migration corridor along 55°N enabled Neanderthal movement between Europe and Asia. |

 | Quantum computers are unable to efficiently recognize the phases of matter in certain quantum states, as the computational time required grows exponentially with the correlation length ξ and becomes super-polynomial in system size n when ξ = ω(log n). This computational hardness applies to a wide range of phases, including symmetry-breaking and topological phases, and persists even for classical phases and both pure and mixed states. |

 | Chimpanzees and bonobos organize their social relationships in layered circles similar to humans, focusing intense grooming on a few partners while maintaining weaker ties with others. Chimpanzees are more selective, especially with age, whereas bonobos distribute social effort more evenly. These patterns indicate shared evolutionary principles in social organization among great apes and humans. |

 | Honey bee colonies replace their queen through supersedure when viral infections shrink her ovaries, reducing egg-laying and production of the pheromone methyl oleate, which signals her fitness. Lower methyl oleate levels prompt workers to rear a new queen. Supplementing colonies with synthetic methyl oleate can reduce premature supersedure, offering a potential management strategy for beekeepers. |
