The increase in marine heat waves in the coming decades, caused by global climate change, should considerably affect the forms of life in this environment, including those at the base of the food chain. This is what a study published in the journal Estuarine, Coastal and Shelf Science by Brazilian researchers who work in Brazil, Norway and the United States points out. Marine heat waves are characterized by periods of more than five days with water temperatures exceeding 90% of the [...]

The new Secretary of Science and Technology of São Paulo, Vahan Agopyan, said that Governor Tarcísio de Freitas (Republicans) will not interfere in the financial and management autonomy of the state universities of São Paulo and FAPESP (Fundação de Amparo à Pesquisa do Estado de São Paulo ). “The governor was very clear in saying that he respects the autonomy, both financial and management, of the institutions and that this will be [...]

Many recent studies suggest that the practice of resistance exercises in polluted environments can produce undesirable effects on human health. But a work recently published in the American Journal of Physiology by scientists from the Study Group on Aerobic Performance at the Faculty of Physical Education and Sports at the University of São Paulo points out that, perhaps, this is not true for practitioners who are already used to vehicle pollution. The team evaluated ten male [...]

The governor-elect of São Paulo, Tarcísio de Freitas (Republicans), appointed this Friday (23) the engineer Vahan Agopyan, former dean of USP, as secretary of Science, Technology and Innovation of the state. Agopyan was one of the academics who signed a manifesto against Tarcísio's election in October, “in defense of science, culture and the public university”. With no party affiliation, the former dean told the Sheet that the future governor knows [...]

Dogs that walk daily with their owners are less aggressive. Dogs owned by women reportedly bark less at strangers. Heavier canines, on the other hand, tend to be less insolent towards their owners than lighter weights. Pugs, bulldogs, shih-tzus and other animals with a shortened muzzle can be more offensive to humans than dogs with a medium and long muzzle, such as the golden retriever and the popular caramel mutt. That's what a study done by researchers from USP (University of [...]

Research carried out in Serrana (313 km from São Paulo), a model city for immunization against Covid-19 in Brazil, proved that mass vaccination reduced death rates and severe cases of the disease even during the circulation of the gamma and delta strains, considered to be of concern due to their faster spread than previous strains. Based on the evolutionary analysis of Sars-CoV-2 (phylogenetics), the scientists showed that the virus replacement dynamics in the city was similar to the [...]

The cerrado is the most threatened of the major biomes in the Brazilian territory. And a particularly vulnerable part are its wetlands, which guarantee the existence of perennial rivers and supply no less than eight hydrographic basins. The Xingu, Tocantins, Araguaia, São Francisco, Parnaíba, Jequitinhonha, Paraná and Paraguay, among other important rivers, originate in the cerrado. The destruction of wetlands is not just a threat to biodiversity and the extraordinary [...]

An article published in the journal Nature Ecology & Evolution this month found that the accumulation of hot spots in the Amazon in August and September 2022 was the highest since 2010. In addition to the record volume, exceeding 74,000 hot spots, the research group found that their cause did not result from extreme drought, as 12 years ago, but from recent human actions of deforestation. “The idea for the publication came up when we analyzed data provided free of charge by the [...]

A study published in the journal Science of The Total Environment demonstrated that pastures with grasses in the Amazon increase the methane sequestration capacity when compared to pasture areas with bare soil. CH4 (methane) is one of the most important greenhouse gases—up to 86 times more capable of trapping heat in the atmosphere than CO2 (Carbon Dioxide). Thus, pasture management strategies have the potential to mitigate climate warming. “We studied the consequences of [...]
