 | Individuals with anxiety disorders exhibit approximately 8% lower choline levels in the brain, particularly in the prefrontal cortex, compared to those without anxiety. Choline is essential for brain function, and most people do not meet recommended intake levels. The findings suggest a potential link between choline deficiency and anxiety, but further research is needed to assess dietary interventions. |

 | A mathematical model demonstrates that Neanderthal disappearance could be explained by genetic dilution through repeated small-scale Homo sapiens immigrations, leading to near-complete replacement of Neanderthal genes within 10,000–30,000 years. This scenario is consistent with genetic and archaeological evidence, though other factors such as environment and competition may have also contributed. |

 | Estrogen enhances learning in female rats by increasing dopamine activity in the brain's reward center, strengthening reward signals. Suppressing estrogen reduces this effect and impairs learning, while decision-making remains unaffected. These findings suggest hormone-driven dopamine modulation may underlie cognitive fluctuations and relate to neuropsychiatric disorder symptoms. |

 | Increasing NAD+ levels corrects RNA splicing errors via the protein EVA1C, restoring gene function and improving memory in Alzheimer's disease models. This mechanism was validated across worms, mice, and human brain samples, linking NAD+ metabolism to RNA processing and protein homeostasis, and suggesting new therapeutic strategies for neurodegeneration. |

 | Pancreatic cancer cells form pseudosynapses that exploit the nervous system by taking up glutamate via NMDA receptors, triggering calcium influx and sustained signaling that promotes tumor growth and metastasis. Blocking these receptors in mice slowed tumor progression and reduced metastases, suggesting a potential therapeutic target. Similar mechanisms may exist in other tumor types. |

 | Analysis of radio galaxy distributions indicates the solar system is moving over three times faster than predicted by the standard cosmological model, with a dipole anisotropy 3.7 times stronger than expected. This significant deviation, confirmed at over five sigma, challenges assumptions about the universe’s large-scale structure or the uniformity of radio galaxy distribution. |

 | Modern imaging has revealed that chameleons possess uniquely long, coiled optic nerves, a structure not found in other lizards and previously overlooked due to limitations of dissection-based studies. This adaptation develops before hatching and likely provides the necessary slack for their eyes' independent, wide-ranging movement, compensating for limited neck mobility and enabling their nearly 360° vision. |

 | Less than a second after the Big Bang, particle interactions in an Early Matter-Dominated Era could have led to the formation of compact objects such as black holes, boson stars, and cannibal stars. These structures may have formed from gravothermal collapse of matter halos, with some primordial black holes potentially accounting for dark matter or evaporating before nucleosynthesis. |

 | A full simulation of a 50-qubit universal quantum computer has been achieved using the JUPITER exascale supercomputer, surpassing the previous 48-qubit record. This was enabled by hybrid CPU-GPU architecture, advanced memory management, and data compression, allowing efficient simulation of complex quantum operations. The simulator will support quantum algorithm development and benchmarking for future quantum systems. |

 | AlphaProof, an AI system developed by Google DeepMind, achieved medal-level performance at the 2024 International Mathematical Olympiad, marking a first for AI. Unlike large language models, AlphaProof guarantees 100% correct solutions by verifying every logical step using the Lean proof assistant. Its training combined large-scale code and math text, expert proofs, and reinforcement learning on millions of problems. |

 | Mass could originate from geometric torsion in hidden extra dimensions, specifically evolving G2-manifolds, rather than from the Higgs field. This approach suggests that particle properties and fundamental forces may emerge from the dynamic geometry of spacetime, potentially explaining mass, symmetry breaking, and the cosmological constant through purely geometric means. |

 | Alterations in the GRIN2A gene alone can directly cause mental illnesses, distinguishing it from previously assumed polygenic origins. Certain GRIN2A variants are linked to early-onset psychiatric disorders, sometimes without other neurological symptoms. Reduced NMDA receptor activity was observed, and L-serine therapy showed symptom improvement, suggesting new diagnostic and treatment approaches. |

 | In patients with prior ischemic stroke, achieving very low LDL-cholesterol levels (<40 mg/dL) is associated with reduced rates of major adverse cardiovascular events and recurrent stroke, without an observed increase in hemorrhagic stroke. These results suggest potential benefits of intensive LDL-cholesterol lowering in this high-risk group. |

 | DNA analysis indicates Adolf Hitler likely had Kallmann Syndrome, a genetic disorder associated with low testosterone, undescended testicles, and micropenis, and showed high genetic predisposition to autism, schizophrenia, and bipolar disorder. The results also rule out Jewish ancestry through his paternal line. These findings do not account for or excuse his actions during World War II. |

 | A time rondeau crystal, a new phase of matter, displays long-range temporal order at specific intervals while exhibiting controllable random fluctuations between them. Using carbon-13 nuclear spins in diamond, this phase was realized and maintained for over 170 cycles. The system allows information encoding in temporal disorder and may enable new quantum sensing or memory applications. |

 | Simulations indicate that carbon nanotubes combined with circularly polarized laser light can generate intense, coherent X-rays on a microchip, potentially replicating the capabilities of large synchrotron facilities in a device only micrometers wide. This approach could enable widespread access to advanced X-ray sources for medicine, materials science, and research, pending experimental validation. |

 | Simulations incorporating magnetic fields demonstrate that massive, fast-spinning black holes like those in GW231123 can form from rapidly rotating stars. Magnetic fields drive outflows that eject stellar material, reducing the final black hole mass and influencing its spin. This process explains black holes in the 70–140 M☉ mass gap and suggests a link between black hole mass and spin. |

 | Deep-sea fishes display a wide range of body shapes, with greater diversity among pelagic species in open water than among benthic species on the ocean floor. Evolutionary rates and pathways differ by habitat: pelagic fish show varied, distantly related forms, while benthic fish are more similar and closely related. Increasing depth accelerates body shape diversification, influenced by environmental factors like darkness and food availability. |

 | A Raman quantum memory using a far-off resonant scheme achieved 94.6% efficiency and 98.91% fidelity, overcoming previous noise and efficiency–fidelity trade-offs. The approach employs atom-light spatiotemporal mapping via the Hankel transform, enabling fast, robust quantum storage and retrieval, and holds promise for advanced quantum communication and computing applications. |

 | Turicibacter, a gut bacterium, significantly reduces obesity and improves metabolic health in mice, even on a high-fat diet. Its beneficial effects are linked to the production of specific bacterial lipids that suppress host ceramide synthesis, a process associated with fat accumulation. Low Turicibacter levels correlate with obesity in humans, suggesting potential for probiotic therapies. |
