Findings may represent promising strategies for promoting muscle function during aging Newswise — BOSTON — Proven to protect against a wide array of diseases, exercise may be the most powerful anti-aging intervention known to science. However, while physical activity can improve health during aging, its beneficial effects inevitably decline. The cellular mechanisms underlying the relationship among exercise, fitness and aging remain poorly understood.   In a [...]

Enhancing the sensitivity of atomic magnetometers used to measure the alpha waves emitted by the human brain is one of the potential applications. Newswise — Scientists are increasingly seeking to discover more about quantum entanglement, which occurs when two or more systems are created or interact in such a manner that the quantum states of some cannot be described independently of the quantum states of the others. The systems are correlated, even when they are separated by a large [...]

December 14, 2022 by Maria Fernanda Ziegler, FAPESP Religion influences secondary school students' understanding and acceptance of evolutionary theory, but social and cultural factors such as nationality, perceptions of science and household income are more influential, according to a study involving 5,500 Brazilian and Italian students aged 14-16. An article on the study is published in the journal PLOS ONE The participants were asked to agree or disagree with a number of statements [...]

Researchers in Brazil and the UK analyzed data for more than 3,000 people aged 50 or more to prove the importance of vitamin D to muscles. Newswise — Vitamin D plays an important role in the regulation of calcium and phosphorus absorption by the organism. It also helps keep the brain and immune system working. Researchers at the Federal University of São Carlos (UFSCar) in Brazil and University College London (UCL) in the United Kingdom have now shown that vitamin D [...]

Nature in Madagascar, an island off southeast Africa slightly larger than metropolitan France, is so unusual that 82% of its plant species and 90% of its vertebrates are endemic, only occurring there. Living amidst this unique biodiversity is a population so deprived that the country’s human development index (HDI) is one of the world’s lowest, posing the challenge of harmonizing conservation with economic and social development. A portrait of Madagascar’s biological riches [...]

Newswise — In Brazil, a group of researchers has reported the largest outbreak to date of COVID-associated candidemia caused by the same drug-resistant strain of Candida parapsilosis, a fungus that invades the bloodstream and can lead to death. The outbreak occurred in 2020-21 in an intensive care unit (ICU) at a tertiary referral hospital in Salvador, Bahia state, during one of the peaks of the COVID-19 pandemic. In an article published in the journal Emerging Microbes and Infections, [...]

The discovery helps explain at the molecular level why some people infected by SARS-CoV-2 develop a potentially fatal systemic inflammation Newswise — Researchers at the University of São Paulo (USP) in Brazil have found that severe COVID-19 is associated with an imbalance in an important immune system signaling pathway. The discovery helps explain at the molecular level why some people infected by SARS-CoV-2 develop a potentially fatal systemic inflammation. It also paves the [...]

In the Cerrado and Caatinga, they use stones as hammers and anvils to crack open cashew nuts, seed pods of Hymenaea courbaril (West Indian locust; jatobá in Brazil) and other hard foods. In an article published in Scientific Reports , Brazilian researchers show that food hardness and tool size do not always correlate as closely as has been thought. In their study, the researchers observed three populations of bearded capuchin monkeys ( Sapajus libidinosus ), measuring food [...]

Conclusion came from a Brazilian study that analyzed active fire occurrences between 2003 and 2020 in the nine countries with Amazon Rainforest areas. Brazil accounted on average for 73% of the fires detected in the period. Brazilian study analyzed active fire occurrences between 2003 and 2020 in the nine countries with Amazon Rainforest areas. Brazil accounted on average for 73% of the fires detected in the period. Newswise — A Brazilian study shows that the number of fires [...]
