Newswise — Even in the wettest parts of the Amazon, the impact of forest fires, which spread through these areas only during extreme droughts, is sufficient to change the characteristics of the vegetation in the coming decades, although it is not as significant as in other parts of the biome. According to an innovative study that measured the effects of fire in situ, burned forest in a wet area loses 27.3% of its stem density on average. The destruction affects mainly trees of small and [...]

Magnetizing a material without applying an external magnetic field is proposed by researchers at São Paulo State University (UNESP), Brazil, in an article published in the journal Scientific Reports, where they detail the experimental approach used to achieve this goal. The study was part of the Ph.D. research pursued by Lucas Squillante under the supervision of Mariano de Souza, a professor at UNESP’s Department of Physics in Rio Claro. Contributions were also made by Isys Mello, [...]

Em um estudo divulgado na plataforma medRxiv, pesquisadores brasileiros deram os primeiros passos para entender por que algumas pessoas são naturalmente resistentes à infecção pelo novo coronavírus. O trabalho se baseou na análise do material genético de 86 casais em que apenas um dos cônjuges foi infectado pelo SARS-CoV-2, embora ambos tenham sido expostos. Os resultados – ainda em processo de revisão por pares – [...]

The study shows that the 2019-20 drought resulted from a natural meteorological phenomenon similar to the one that caused the 2014-16 critical water shortage in São Paulo state, Southeast Brazil. Fundação de Amparo à Pesquisa do Estado de São Paulo The extreme drought suffered by the Pantanal in 2019-20, considered the worst in the last 50 years, was caused by natural climate conditions similar to those underlying the 2014-16 water crisis in São Paulo [...]

Pantanal'in son 2019 yilin en kötüsü olarak kabul edilen 20-50'de yasadigi asiri kuraklik, São Paulo eyaletindeki 2014-16 su krizinin altinda yatanlara benzer dogal iklim kosullarindan kaynaklandi. Pantanal, dünyanin en büyük sulak alanlarindan biridir. Brezilya kismi, Merkez-Bati bölgesinde, özellikle Mato Grosso do Sul eyaletinde yer almaktadir. 2019-20 asiri kuraklik, Dogal Afet Gözetleme ve Erken Uyari Merkezi (CEMADEN), Ulusal [...]
