An article recently published in Science, titled "The global tree restoration potential," presented what it called "the most effective solution at our disposal to mitigate climate change." The lead author is Jean-François Bastin, an ecologist affiliated with the Swiss Federal Institute of Technology (ETH Zurich). The article reports the results of a study in which Bastin and collaborators used remote sensing and modeling techniques to estimate that forest restoration [...]

Researchers at the University of São Paulo (USP) in Brazil have described a system present in a species of opportunistic bacterium found in hospital environments that injects a cocktail of toxins into competing bacteria and completely eliminates them. This discovery can be used in the future development of new antimicrobial compounds. The study was supported by São Paulo Research Foundation—FAPESP and published in PLOS Pathogens by researchers affiliated with USP's [...]

In an article published in the journal PLOS ONE, a group of researchers supported by FAPESP has updated the description of the Ghost knifefish, Tembeassu marauna, a neotropical electric fish species found only once in the wild. The study, conducted in Brazil, was based on an analysis of external anatomy and internal details that could be seen thanks to an advanced, high-resolution computed tomography (CT) technique that revealed characteristics of the fish's bones without requiring [...]

In the 2019 harvest, members of the Landless Workers' Movement (MST), in Rio Grande do Sul state, Brazil, commemorated a harvest estimated at 16,000 tons of organic and agroecological rice, the biggest production of its kind in the whole country. 363 families in 15 settlements work in the rice production. In the south of the state of Minas Gerais, 20 families of the Campo Grande "quilombo" community produce Guaií organic and agroecological coffee, internationally [...]

Say hello to two new species of electric eel, including one that can discharge up to 860 volts, the strongest of any known animal, researchers say. Electric eels send out an electrical discharge to stun prey. After analyzing data on 107 specimens from the Amazon in Brazil, Suriname, French Guiana and Guyana, researchers from São Paulo Research Foundation and the Smithsonian’s National Museum of Natural History concluded thatnaked-back knifefishshould be reclassified into two new [...]

There are at least three species of electric eels (Electrophorus spp.), not just one as previously believed. Two new species have recently been described with São Paulo Research Foundation—FAPESP's support by a group of researchers affiliated with the Smithsonian Institution and National Geographic Society, among other institutions. One of the new species can discharge up to 860 volts, the strongest of any known animal. Electric eels are naked-back knifefishes (Gymnotidae) and [...]

Titanium oxide (TiO2) nanofibers can have various applications, such as in catalyzers and filters. When TiO2 is excited by ultraviolet light, it degrades organic material. Hence, TiO2 can be applied to filter wastewater for reuse, for example. A new method of fabricating these fibers has been developed in Brazil by Rodrigo Savio Pessoa and Bruno Manzolli Rodrigues, researchers at the Aeronautical Technology Institute's Plasma and Process Laboratory (LPP-ITA) and the Science and Technology [...]

Corn starch, an abundant, cheap and biodegradable raw material, is the basis for a novel larvicide developed by researchers at the University of Campinas (UNICAMP) in São Paulo State, Brazil. The material is used in microcapsules for storage and controlled release of active compounds to kill larvae of Aedes aegypti, the mosquito that transmits dengue, zika, yellow fever, and chikungunya. A patent application has been filed via UNICAMP's innovation agency (Inova). The methodology is [...]

The main finding is that skipping breakfast, a common habit among teenagers, correlates directly with increased waist circumference and body mass index in this age group.The habit can lead to an unbalanced diet and other unhealthy behaviors, potentially making the adolescents vulnerable to weight gain. "We found that skipping breakfast is associated with adiposity markers in adolescents regardless of where they live and how much sleep they get, or whether they're male or female," [...]
