Concrete is an essential material in the construction industry, where it is fundamental to the foundations and structures of dwellings and office buildings, as well as roads, dams and bridges, among many other infrastructure projects. However, the service life of concrete is limited, and it must be monitored in order to guarantee the safety of these structures. To facilitate fast, low-cost, in-situ analysis that dispenses with the need to take samples to a laboratory, researchers at the [...]

Propolis has long been used in traditional medicine and has won attention from the scientific community following proof of its health benefits, which include antioxidant, anti-inflammatory, antimicrobial, antitumor and immunomodulatory properties. Its composition varies according to origin, geographic location, and the bee species that produces it. Researchers affiliated with São Paulo State University (UNESP) in Brazil and the University of Southern Denmark (SDU) set out to analyze [...]

Study mapped knowledge of nature-based solutions among municipal staff responsible for projects in 20 Brazilian cities. The survey points to the need to adapt the approach used in the northern hemisphere to local conditions Initiatives involving nature-based solutions (NbS) are increasingly frequent in Europe and the United States, but still scarce in Brazil and rarely part of local public policy even when mayors are aware of the concept. This is one of the findings of a survey conducted [...]

A study by a group at the University of São Paulo reported in a scientific journal involved the construction of a database and models. Preliminary results are described in the article. Researchers at the University of São Paulo (USP) in Brazil are using artificial intelligence (AI) and Twitter, one of the world’s largest social media platforms, to try to create anxiety and depression prediction models that could in future provide signs of these disorders before clinical [...]

The news gave different weights to some threats when juxtaposed with the Red List of Threatened Species maintained by the International Union for the Conservation of Nature (IUCN) Peer-Reviewed Publication  A group of researchers supported by FAPESP analyzed 192 news reports published on the internet between 2011 and 2021 on Brazilian deer species (Cervidae) in order to find out whether news of threats to these animals matched the actual risk of their extinction. In an article on [...]

The study analyzed fossilized bones from three Brazilian species of the Late Triassic (about 233 million years ago), the period in which the dinosaurs emerged. All the bones were found in recent decades in Rio Grande do Sul, Brazil’s southernmost state Dinosaurs as big as buses or five-story buildings would not be possible if their bones were dense and heavy like ours. Like present-day birds, dinosaurs had hollow bones with inner structures known as air sacs, which made their skeletons [...]

Microplastic particles separated from a sediment sample from the Guarapiranga reservoir in metropolitan São Paulo show different particle sizes In the last decade, growing numbers of researchers have studied plastic pollution, one of the world’s most pressing environmental hazards. They have made progress but still face challenges, such as the comparability of results, especially with regard to microplastic particles. There is no standard sample collection and analysis [...]

A Brazilian study identified more than 74,000 active fires in the period. Half of the Amazon is typically vulnerable to fire in period analyzed. Human action was the main cause of the recent destruction. 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 [...]

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 supplementation reduces the risk of dynapenia in older people by 78%. Dynapenia is an age-associated loss of muscle strength. It can be partially explained by muscle [...]
