'Blood rain' flows down Iranian mountain - video

The Stunning Transformation of Hormuz: A Crimson Coastal Marvel A breathtaking natural phenomenon has made the Iranian island of Hormuz a topic of global discussion. In December 2025, its shores were transformed into a surreal blood-red landscape, capturing the fascination of tourists, scientists, and nature enthusiasts alike. This extraordinary event, triggered by heavy rainfall, turned Hormuz 's beaches and shallow waters a striking crimson hue, generating amazement, curiosity, and even concern online.  The Science Behind the Spectacle The scientific explanation for this spectacular phenomenon lies in the island's unique geology. Hormuz is characterized by a rich presence of iron oxide, particularly hematite, a mineral known for imparting a deep reddish hue to the soil and rocks. When rainwater seeps through the island's iron-rich soil, it dissolves and carries iron oxide particles toward the coast. This process enhances the reddish color of the sand and water, particular...

A mountain was split in China to build one of the world's tallest bridges

  In the remote mountains of China's Guizhou province, an engineering feat is taking shape that is destined to enter history: the Huajiang Canyon Bridge . Once completed, this suspended bridge will be the tallest in the world, spanning the canyon at an impressive height of 625 meters above the ground. To give an idea of its magnitude, the Eiffel Tower could pass underneath without touching it. An Ambitious Project The Huajiang Canyon Bridge is an integral part of the Liuzhi–Anlong Expressway , a new 152-kilometer roadway designed to connect this mountainous region to China's high-speed road and rail network. This project will not only improve accessibility to the area but also represents a significant step toward the economic and social development of the province. The Ministry of Foreign Affairs of the People's Republic of China shared a video of the project on social media, accompanied by the caption: "For the people and development, no mountain is too high....
