In 2018, Brazilian and British scientists were exploring the seafloor around a volcanic plateau known as the Rio Grande Rise when they spotted rocks that looked like they belonged on dry land. Watching video relayed from their remotely operated submersible 650 meters (2,100 feet) below the surface, unusual red clay layers caught their attention. "You just don't find red clay on the seabed," said Bramley Murton, a marine geologist from the National Oceanographic Centre in [...]

The first half of Jair Bolsonaro's presidency was so destructive for the Amazon that it was comparable to the record 2016 El Niño drought and heatwave in terms of carbon emissions, according to scientists. Annual emissions from the world's largest rainforest roughly doubled in 2019 and 2020, compared with the 2010 to 2018 average, according to a new study published in Nature, as swaths of forest were deliberately cleared and burned for cattle ranching and farming during the [...]

Amazon dark earth boosts tree growth as much as sixfold A type of soil called terra preta da Amazônia, or Amazon dark earth (ADE), promotes faster growth of trees and enhances their development in qualitative terms, according to an article published in the journal Frontiers in Soil Science. The findings reported in the article resulted from studies supported by FAPESP (projects 20/08927-0, 18/19000-4 and 14/50320-4) under the aegis of its Biodiversity, Characterization, [...]

Between approximately 450 BCE and 950 CE, millions of Amerindian people living in today’s Amazonia transformed the originally poor soil through various processes. Over many human generations, soils were enriched with charcoal from their low-intensity fires for cooking and burning refuse, animal bones, broken pottery, compost, and manure. The result is Amazonian dark earth (ADE) or terra preta, exceptionally fertile because rich in nutrients and stable organic matter derived from charcoal, [...]

The geology of Brazil’s volcanic Trindade Island has fascinated scientists for years, but the discovery of rocks made from plastic debris in this remote turtle refuge is sparking alarm. Melted plastic has become intertwined with rocks on the island, located 1,140 km (708 miles) from the southeastern state of Espirito Santo, which researchers say is evidence of humans’ growing influence over the earth’s geological cycles. “This is new and terrifying at the same [...]

- video at link - A Mysterious Ring Surrounding Dwarf Planet Puzzles Astronomers unbranded - Newsworthy / VideoElephant Astronomers have been left baffled following the discovery of a ring around a dwarf planet. The rare occurrence has been observed inside our solar system around a newly discovered mini-planet, named Quaoar. Quaoar is around half the size of Pluto and orbits the Sun past Neptune. What makes the ring around Quaoar unusual is the distance between the system and the [...]

The biodiversity of terrestrial insects in Brazil, which includes animals such as butterflies, bees, and beetles, is on a downward trend. This is one of the results of a survey carried out by researchers from the State University of Campinas (Unicamp) and the federal universities of São Carlos and Rio Grande do Sul. The information was gathered from 45 scientific pieces of research on the theme, besides questionnaires sent to researchers who have been studying insects for [...]
