This Chinese ghost town became one with nature
|
view preview
An old fishing village on the island of Shengshan on the Yangtze River was abandoned for economic reasons, only to become one with nature. The island, a few hours east of Hangzhou Bay, is a stark contrast to the vibrant metropolitan skyline of nearby Shanghai - an image conjured up in many westerners' minds when imagining populous China. Some of the islands at the mouth of the Yangtze river are popular tourist destinations and have been described as a paradise for seafood lover, while others are inhabitable. The stunning scenery on Shengshan Island is the result of the houses and outbuildings being slowly consumed by nature. The seaside village now lies empty because it was more economical for the fishermen to move and work on the mainland ...

All trees, regardless of size, break once this wind speed is reached

The magic number is 42 m/s (94 mph). Using mathematical data and physical experiments, scientists say they have found the law that governs the resistance of wooden beams under stress. According to the study ( link), researchers hung weights from wooden rods and pieces of pencil lead to record the amount of force needed to snap the cylinder. As one might sense, they found that for a fixed length, increasing the diameter made the rods stronger: They could bend more before breaking. This would make tall skinny trees most vulnerable, but, as the team points out, trees don’t grow taller without getting disproportionately thicker as well. By incorporating established laws of tree allometry - which explain the relationship of tree size parameters ...

World's deadliest tree
|
view preview
The manchineel tree ( Hippomane mancinella) has taken the title of world’s most dangerous tree. This evergreen grows up to 15 metres (49 ft) tall, and is native to tropical southern North America and northern South America. It has reddish-greyish bark, small greenish-yellow flowers, and shiny green leaves ranging in size from 5 to 10 cm (2–4 inches) long. All parts of the tree contain strong toxins, some unidentified. The leaves and fruit of the tree superficially resemble an apple tree, however one bite of the tree’s fruit can cause abdominal pain, vomiting, bleeding, or death due to an acetylcholine inhibitor known as physostigmine found in the fruit.

The year summer was erased
|
view preview
The eruption of Mount Tambora was so massive, it erased summer that year.The 1815 eruption of Mount Tambora was one of the most powerful eruptions in recorded history. The eruption of the volcano, on the island of Sumbawa in the Dutch East Indies (present-day Indonesia), reached a climax on 10 April 1815 and was followed by between six months and three years of increased steaming and small phreatic eruptions. The ash from the eruption column dispersed around the world and lowered global temperatures, leading to worldwide harvest failures in an event sometimes known as the Year Without a Summer in 1816. The eruption resulted in a brief period of significant climate change that led to various cases of extreme weather. Several climate forcings ...
