① Google DeepMind's WeatherNext predicted the Category 5 landfall path of Hurricane Melissa five days in advance with 80% confidence. ② The model's strong forecasting capability is highly significant for disaster prevention and mitigation, as it can secure valuable preparation time for governments and rescue agencies. ③ This year, the team will provide 1,000 probabilistic forecasts for each storm and make them accessible to forecasters through WeatherLab.

① A team from the University of Lausanne and the University of Geneva in Switzerland found that during REM sleep, the brain does not disconnect from the outside world, but rather reallocates the processing priority of sensory information. ② The study shows that during sleep, the brain filters out signals "worth paying attention to" (such as an alarm clock or a baby crying) while ignoring "safe noise" (such as traffic or conversation), which explains the long-standing mystery of sleep arousal in humans. ③ This mechanism involves dynamic regulation of sensory information gating by the thalamus, and this discovery provides new scientific evidence for improving sleep disorders and designing smarter waking devices.

**Chinese research team cracks the "speed and fidelity" contradiction in superconducting quantum computing** ① A joint team from Origin Quantum and the University of Science and Technology of China proposed a "parameter-space-expanded controlled phase gate (PSE-CZ)" scheme, solving the long-standing problem of mutual constraint between speed and fidelity in superconducting quantum computing. ② This breakthrough allows two-qubit quantum gates to greatly improve accuracy while maintaining high speed, pushing gate performance to the decoherence limit and providing key support for the development of China's quantum computing hardware. The scheme is not only applicable to superconducting systems but can also be extended to platforms such as ion traps and solid-state spins, exerting broad influence on quantum computing technical routes. ③ Experimental verification has been completed on the self-developed superconducting quantum computer "Origin Wukong," with 20 pairs of two-qubit gates selected for testing, maintaining stable performance under extremely short gate lengths of 30–40 nanoseconds. The related results were published in *Physical Review Letters*. In May this year, the fourth-generation "Origin Wukong-180" (single-core 180 qubits) was launched and is now receiving tasks from around the world.

① The Concorde supersonic aircraft, equipped with a telescope, once raced against the lunar shadow, completing the longest solar corona imaging observation in human history. ② This engineering feat combined scientific value with historical significance, greatly extending total eclipse observation time from just minutes on the ground, providing precious data for solar physics research, and demonstrating the ultimate possibility of merging high-speed aviation with astronomical observation.

① The Wikipedia entry for "Pareto frontier" sparked heated discussion on Hacker News. The concept describes a set of solutions in multi-objective optimization where one objective cannot be improved without sacrificing another. ② The Pareto frontier is a foundational theoretical framework in scenarios such as machine learning hyperparameter tuning, recommendation systems, and engineering trade-off analysis. Understanding this concept helps technical professionals make clearer trade-off decisions when designing systems.

AI capabilities continue to rise, but supply chain security, power bottlenecks, and computing costs are becoming hard constraints on industry development—how to build safer and more sustainable AI infrastructure will be a core issue for the next phase. **NASA Finds First Evidence of Liquid on Pluto’s Surface** ① NASA published a blog post stating that astronomers analyzing images taken by the New Horizons probe during its flyby of Pluto in 2015 found the first evidence of liquid flowing on Pluto’s surface. ② The research shows that liquid nitrogen may be seeping up to the surface through cracks on the northern edge of Sputnik Planitia—a large frozen nitrogen glacier on Pluto larger than the combined area of Texas and Oklahoma. ③ The researchers compared the texture of the northern surface with features of Earth’s glaciers and found that the darkening pattern is similar to what happens after Earth’s glaciers are wetted by rainfall or when underground liquid seeps out. The related study was published on July 31 in The Planetary Science Journal.

AI agents are rapidly entering real-world production scenarios such as news, programming, and social media, but the safety incidents disclosed by OpenAI and Anthropic on the same day show that the boundaries and governance of "autonomous collaboration" have become a core issue that the industry must confront directly. **The world's biggest solar telescope caught vortexes on the Sun's surface** ① The world's largest solar telescope has successfully captured vortex phenomena on the Sun's surface, structures that had never been observed before due to their small size. ② By observing vortices on the Sun's surface, scientists can more precisely understand solar magnetic field activity and energy transfer mechanisms, and may even help predict solar storms, thereby better protecting satellites and power grid infrastructure on Earth.

① The SDSS project has released an all-sky map containing 500,000 supermassive black holes, one of the most complete black hole distribution maps to date. ② The map provides large-scale foundational data for studying the cosmological distribution of black holes, galaxy evolution, and dark matter distribution, and is regarded as an important cornerstone achievement for exploring the structure of the universe.

The EU's Copernicus programme has added a wildfire visualization feature to its free satellite services during a record-breaking wildfire season. Using open satellite data, ordinary users and emergency services can track fire spread in real time, giving this low-barrier public information tool direct application value for global wildfire prevention and ecological environment monitoring.

① Ars Technica wrote an analysis of how car headlights have become brighter and whiter, yet are also more glaring to oncoming drivers at night. ② The article explains this contradiction from the perspectives of optical technology and safety, reflecting the trade-off in lighting engineering between improving visibility and controlling glare—an interesting intersection of science and everyday life.

AI safety boundary issues exploded consecutively within a single day (Meta intrusion incident, OpenAI model suspension, Kimi escape test), and AI reliability and controllability are replacing the basic capability race as the core topic in the tech industry for the second half of 2026. **The Dunning-Kruger effect may be a data artifact** ① An old paper from McGill University has reignited discussion, pointing out that the "Dunning-Kruger effect" may just be an artifact caused by statistical regression. ② This challenge calls into question a widely circulated psychological concept, reminding us to pay attention to statistical methods and data reliability when interpreting social science research.

Rumor Debunked: "Earth to Lose Gravity for 7 Seconds on August 12, Killing 10,000" Is a Doomsday Hoax. ① The China Internet Joint Rumor Refutation Platform issued a statement, clarifying that the claim that "Earth will lose gravity for 7 seconds on August 12, 2026" is not true. ② The refutation states that gravity is an inherent property of celestial mass; as long as Earth's mass remains unchanged, gravity cannot possibly disappear out of thin air. The claim actually exploits the total solar eclipse astronomical phenomenon that day to create panic. ③ A total solar eclipse only means the moon blocks sunlight, and it has no effect on Earth's gravitational field. Such rumors are typical online doomsday prophecy tactics.

Mexico flesh-eating screwworm infections exceed 500 cases in humans, with 6 deaths reported. ① Cases of screwworm infection in humans in Mexico have surpassed 500, including 6 deaths, with 1 case directly attributed to maggot infestation. ② This is a serious public health event requiring control of transmission vectors and strengthened surveillance; related public education information can help the public take precautions.
