Brasil habría evitado la muerte de unos 47.000 ancianos, así como la hospitalización de otros 104.000, en caso de que hubiese anticipado o intensificado su campaña de vacunación contra la covid, según un estudio publicado este lunes. El gigante latinoamericano, uno de los dos países más castigados por la pandemia en el mundo, con cerca de 689.000 muertes y más de 35 millones de contagios, tan solo inició su campaña [...]

The Pantanal represents 1.8% of Brazil’s total area, occupying 150,000 square kilometers in Mato Grosso and Mato Grosso do Sul states. With a mixture of floodable and non-floodable savannas, meadows, pastures and forests, the macro-region contains the world’s largest floodplain. Together with the Chaco region, which lies further south, the Pantanal is a complex of wetlands with ample biodiversity that provides cultural and ecosystem services to Brazil, Bolivia and Paraguay. As in [...]

For the first time, scientists at the Federal University of São Paulo (UNIFESP) in Brazil have shown that infection by SARS-CoV-2, the virus that causes COVID-19, changes the functioning of host cell RNA. They arrived at this conclusion by analyzing 13 datasets obtained during four studies of viral, human and animal cell RNA. The most recent study, reported in an article published in Frontiers in Cellular and Infection Microbiology, examined the epitranscriptome of Vero cells (derived [...]

Tiger Beach in the Bahamas is famous for its paradisiacal beauty and for being frequented by an animal that might scare most people away but is actually an outstanding diving tourism attraction: the Tiger shark (Galeocerdo cuvier). The sea is crystal clear and only 5 m deep on average, so the sharks, which can surpass 3 m in length, can easily be seen. They are drawn to the site by local tour operators, who throw fish and other food into the water. A group of scientists in Brazil and the [...]

No Brasil, há cerca de 10 milhões de hectares de plantações comerciais de madeira, dos quais aproximadamente 80% são compostos por eucalipto destinado majoritariamente à produção de papel e celulose. Mais da metade das plantações dessa árvore no país usam um único clone (plantas com a mesma composição genética), contou Pedro Brancalion, professor da Escola Superior de Agricultura Luiz [...]

Oito universidades paulistas serão interligadas por uma rede de fibra óptica de alta velocidade que, além da conexão entre elas, permitirá troca de informações com instituições estrangeiras. Chamada de Backbone SP, a rede está em fase de instalação e já está disponível na Universidade Federal de São Paulo (Unifesp) e na Universidade Federal do ABC (UFABC). A iniciativa vai [...]

Spin is the intrinsic magnetic moment of a particle—an electron, for example. It is a fundamental magnitude, like mass and charge. Simply put, it is as if the particle had a magnet inside it that enabled it to interact, even while at rest, not only with the spins of other particles but also with external magnetic fields. By analogy with usual liquids, a system in which spins do not exhibit magnetic order, even at temperatures close to absolute zero, is termed a spin liquid. In [...]

An application developed in collaboration with vulnerable communities to transmit early warnings of the risk of floods and environmental disasters has become public policy in Brazil, and the methodology is being replicated for use elsewhere. With practical results obtained in 2022, part of the discussions involving proposals to improve flood risk governance began at least two years ago. An article published in Disaster Prevention and Management: An International Journal reflects one of the [...]
