Researchers at São Paulo State University (UNESP) in Brazil have developed a strategy for removing glyphosate, one of the world's most frequently used herbicides, from water. Inspired by the concept of the circular economy, the technique is based on sugarcane bagasse, a waste material produced by sugar and ethanol plants. Application of glyphosate-containing products is restricted or banned in Austria, Bulgaria, Colombia, Costa Rica, Denmark, El Salvador, Germany and Greece, among [...]

The consequences of climate change in the Caatinga, the semi-arid shrubland and thorn forest biome in Brazil’s Northeast region, will include species loss, substitution of rare plants by more generalist vegetation, biotic homogenization (in which previously distinct plant communities become progressively more similar), increasing aridity, and even desertification in some areas.  These are some of the findings of a study reported in the Journal of Ecology by [...]

An international study has revealed strong associations between oral health and survival among people diagnosed with head and neck cancer. Specifically, better oral health, as evidenced by the number of natural teeth and dental visits prior to the time of diagnosis, was associated with increased survival. Importantly, those who had more frequent dental visits were more likely to have their cancer diagnosed at an earlier, and less deadly, stage of the disease than those who had few or no dental [...]

A research project supported by FAPESP shows that the construction of new hydroelectric power plants in Brazil’s South region could have an impact on more than 30% of the habitat of Phrynops williamsi, the Williams’ side-necked turtle. The species occurs only in areas of Atlantic Rainforest and Pampa (the grassland biome adjacent to Brazil’s border with Uruguay and Argentina), and is classed as “Vulnerable” (facing a high risk of extinction) by the [...]

As global temperatures continue to reach all-time highs and discussions intensify about ways to mitigate the adverse effects of climate change, researchers at the University of São Paulo’s Luiz de Queiroz College of Agriculture (ESALQ-USP) in Brazil have reported the results of a scientific study showing that if all the country’s active legal mining sites continue to operate in the coming decades, emissions will total an estimated 2.55 gigatonnes of equivalent carbon dioxide [...]

 Acetone is an essential chemical industry input and is used in the manufacturing of a wide array of products, such as adhesives, antibiotics,  electronic components, solvents and removers, inks and vitamins, among others. Its production is complex and hazardous. To simplify the process and make it safer and cheaper, researchers in Brazil and Germany have developed an innovative method that uses only light and photoactive iron chloride (FeCl3), an inexpensive chemical [...]

Oral health deteriorates in morbidly obese people on a diet in preparation for bariatric surgery and patients who have undergone the procedure, with increasing caries, gingivitis and periodontitis. This is the conclusion of a study conducted by researchers at the Federal University of São Paulo (UNIFESP) in Brazil. Articles on the study are published in the Journal of Oral Rehabilitation and Clinical Oral Investigations, stressing the importance of participation by a [...]

About a third of the restaurants listed on iFood, the food delivery app most used by Brazilians, are “dark kitchens”, according to the first study of the topic conducted in Brazil, and one of only a few worldwide. An article on the study is published in the journal Food Research International. It has eight authors; the first three and the last are researchers at the State University of Campinas (UNICAMP) in São Paulo state. Defined in the article as delivery-only [...]

Factors such as technological advancement, globalization and demographic changes are transforming the world we live in, making it more turbulent, polarized and unpredictable. This tension manifests itself through climate change, heightened migration crises, ethnic conflicts, socioeconomic inequality and authoritarianism, as well as a growing lack of trust in institutions. To address these and other global challenges, scientists around the world must cross borders and work [...]
