To a driver passing Fish Lake on State Route 25, in Utah, an aspen grove would look just like a forest of pale trunks. But this is isn’t your average forest. Rather, it’s a single quaking aspen masquerading as a forest; one organism, spread across 106 acres (43,000 square meters), joined underground by one living […]

A atualização anual da chamada "lista 1260H" alarga o escrutínio dos EUA a gigantes tecnológicos e industriais chineses não estatais que, em princípio, não teriam qualquer ligação ao setor da defesa. A medida surge menos de um mês após a cimeira de Trump em Pequim. A China prometeu retaliar.

Deep in Taiwan’s misty mountains, researchers have confirmed the tallest tree in the country: a thousand-year-old fir tree higher than a 20-story building, which they’ve named “the heaven sword of the Da’an River.” Climbers scaled the tree and dropped a measuring tape from the top to the forest floor during the Lunar New Year holiday in January 2023. The tree measured 84.1-meters (276-feet). The findings have been published in Frontiers in Forests and Global Change. A team of ecologists, geologists, remote-sensing specialists, professional climbers and Indigenous people that calls itself the “Taiwan tree seekers” began the search in 2014. “The common characteristics [of the team] are probably that we are all tree lovers and like adventures,” Rebecca Chia-Chun Hsu, lead author from Division of Forest Ecology, Institute of Taiwan Forestry Research, told CNN. ‘The Heaven Sword’, Taiwan’s tallest tree, measures 84.1 meters.

The island sits where the tropics meet the subtropics, and its mountains host several giant conifer species. The species behind the new record, Taiwania cryptomerioides, is known to the Indigenous Rukai people as “the tree that hits the moon.” Although nearly 60% of Taiwan is covered in forest, loggers cleared much of the island’s old-growth forest between 1912 and 1991. However, its steep slopes were too dangerous to reach, and pockets of ancient forest survived. Still, finding the tallest tree amid the rugged terrain was a task.

Deep in the mountains of northern Taiwan, a towering Taiwania cryptomerioides -- a large coniferous tree in the cypress family Cupressaceae whose ancestors date back 100 million years -- has been confirmed as the tallest known tree in East Asia.
