"Triple-Arrow Assault" Confirms a Cosmic "Natural Accelerator" Ejecting Protons at Energies 100 Times That of the Large Hadron Collider

Astronomers, using three observation facilities operating in different wavelength bands, have confirmed a mysterious celestial body in the direction of the Aquila constellation in the Milky Way as a natural cosmic accelerator. This object is continuously ejecting high-speed particles with energies far exceeding any man-made accelerator on Earth, equivalent to 100 times that of the Large Hadron Collider (LHC). This discovery provides key clues for tracing the origin of the highest-energy cosmic rays in the Milky Way, and the research findings were published in the latest issue of The Astrophysical Journal.

Linn County, Iowa, rejects rezoning application for data center site near nuclear power plant

The Linn County Board of Supervisors in Iowa said Monday it will not proceed with amendments to the EU-2 zoning district. This decision means that large data centers will not be permitted to be built near nuclear facilities through this zoning rule for the time being. The current EU-2 zoning primarily allows for nuclear power generation facilities, nuclear waste storage facilities, and natural gas power generation facilities, and does not list large data centers as permitted uses. The zoning adjustment drew attention due to the potential restart of the Duane Arnold Energy Center near Palo. If the nuclear facility were to resume operations, it could provide a stable power source for energy-intensive data centers, prompting interest from data center companies in surrounding...

Typhoon "White Dolphin" Approaches Fujian-Zhejiang Coast, Ningde Nuclear Power Initiates Typhoon Emergency Deployment

According to the forecast of the Central Meteorological Observatory, Typhoon White Dolphin is expected to make landfall along the coast from Zhoushan, Zhejiang to Fuding, Fujian between the night of August 9 and the morning of August 10, with an intensity of 12 to 14 levels at landfall, classified as a typhoon or severe typhoon. Affected by this round of typhoon, Fujian has upgraded its emergency defense level. The Fujian Provincial Meteorological Observatory upgraded the typhoon warning to Level II at 9:00 on August 9, and the Fujian Provincial Flood Control and Drought Relief Headquarters upgraded the typhoon emergency response to Level II at the same time. Heavy to torrential rain is expected in northern Fujian from August 9 to 10, with localized extremely heavy rain. State Grid Fujian Electric Power has issued a Level III warning for typhoon and rainstorm, and activated a Level IV emergency response for typhoon, rainstorm, and flood disasters. Located in Fujian...
