As global temperatures continue to reach all-time highs and discussions intensify about ways to mitigate the adverse effects of climate change, researchers at the University of São Paulo’s Luiz de Queiroz College of Agriculture (ESALQ-USP) in Brazil have reported the results of a scientific study showing that if all the country’s active legal mining sites continue to operate in the coming decades, emissions will total an estimated 2.55 gigatonnes of equivalent carbon dioxide [...]

Brazilian researchers combined environmental physical, social and economic indicators to create an index that measures a region's vulnerability and used it to analyze the basins of the Parnaíba River and São Francisco River in the Northeast of Brazil. The index is named SEVI (for Socio-Environmental Vulnerability). The Parnaíba and São Francisco basins are considered crucial to agricultural expansion and biodiversity conservation. They contain more than 780 [...]

About a third of the restaurants listed on iFood, the food delivery app most used by Brazilians, are “dark kitchens”, according to the first study of the topic conducted in Brazil, and one of only a few worldwide. An article on the study is published in the journal Food Research International . It has eight authors; the first three and the last are researchers at the State University of Campinas (UNICAMP) in São Paulo state. Defined in the article as delivery-only [...]

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, Conservation, Restoration and Sustainable Use Program ( BIOTA [...]

An article to be published in Nature Ecology & Evolution reveals that Luzio, the oldest human skeleton found in São Paulo state (Brazil), was a descendant of the ancestral population that settled the Americas at least 16,000 years ago and gave rise to all present-day Indigenous peoples, such as the Tupi. Based on the largest set of Brazilian archeological genomic data, the study reported in the article also offers an explanation for the disappearance of the oldest coastal [...]

Tropical mountain ecosystems, including montane forests, are relatively little studied, yet they are home to significant biodiversity and provide important ecosystem services, such as water supply and participation in regulation of temperature and regional and global climate. The data available on mountain vegetation and its dynamics falls far short of what is needed to simulate with confidence its interaction with the atmosphere in response to climate change. A new study published in the [...]

The number of active fires recorded in the Brazilian Amazon in August-September 2022 was the highest since 2010, according to an article published in the journal Nature Ecology & Evolution. Besides the record number of fires (74,398), the researchers found they were due not to extreme drought, as in 2010, but to recent deforestation by humans. “The idea of publishing our findings came up when we analyzed data provided free of charge by the Queimadas program,” said Guilherme [...]

Despite similarities with other Neotropical biomes like the Caatinga (a mosaic of scrub with patches of seasonally dry forest in Northeast Brazil) and Cerrado (savanna in Central Brazil), the Gran Chaco, or simply Chaco, is globally unique. Located mainly in Bolivia and Argentina, with patches in Brazil and Paraguay, the region is the world’s largest continuous dry tropical forest. Snakes must adapt in various ways to survive there. Sheltering from the sun and climbing trees are [...]

For many soccer fans, penalties are moments of utmost tension and potential glory. In 2019, the International Football Association Board (IFAB), which establishes the laws of the sport, decided to allow goalkeepers to put one foot in front of the goal line as a penalty is kicked, giving in to the demands of goalkeepers and overruling fears that referees would have to repeat too many penalties. Previously, both of the goalkeeper’s feet had to be on or behind the line until the moment the [...]
