The adoption of management techniques that reduce the impact of timber harvesting can promote the recovery of tropical forests, such as the Amazon, and store carbon in the long term while maintaining biodiversity and ecosystem services. Research published in the Journal of Environmental Management provides evidence that these good practices increase above-ground biomass, unlike conventional logging. This reinforces the effectiveness of reduced-impact logging forest management (RIL-FM) as a [...]

Brazilian researchers have developed an index that can measure the health of mangrove soils at different stages. When applied to degraded, restored, and preserved areas, the index revealed that healthy mangroves, including recovered ones, provide ecosystem services at nearly maximum capacity. In contrast, deforested mangroves have only a small fraction of this potential. The Soil Health Index (SHI) ranges from 0 (worst) to 1 (best) and is described in an article published in the journal [...]

Initial tests with a natural dye produced by the Amazonian fungus Talaromyces amestolkiae show that eco-friendly cosmetics, such as face creams, gel sticks, and shampoos, can be developed with antioxidant and antibacterial properties. This finding is significant because microbial dyes, which are still under-explored in cosmetic research, can serve as a sustainable alternative to synthetic dyes. The fungus produces vibrant dyes ranging from red to yellow with high industrial potential. [...]

Scientists have discovered that a widely recognized Amazonian antbird is not one, but five distinct species – including two completely new to science. This revelation of hidden biodiversity was achieved by integrating artificial intelligence, vocal analysis, and traditional museum work, demonstrating how cutting-edge technology can transform our understanding of life in Earth's richest ecosystems. The study was conducted by Vagner Cavarzere and his master’s student Enrico L. [...]

Researchers at the University of São Paulo (USP) in Brazil have discovered a set of genes that can predict how viral hepatitis may progress in the body. They call this network of genes the “neuroimmunoma,” which connects the nervous and immune systems. The neuroimmunoma can serve as a biomarker to predict the severity of liver damage and the risk of liver cancer resulting from a hepatitis virus infection. The study was supported by FAPESP and published in the Journal of Medical Virology [...]

Even the most remote regions of the globe are not free from plastic pollution. In a study published in Marine Pollution Bulletin , researchers from São Paulo State University (UNESP) in Brazil detected plastic rocks on Trindade Island, the easternmost point of South America. They also found that green turtle (Chelonia mydas) nests are particularly conducive to plastic accumulation and burial. This increases the likelihood that plastic will remain in the geological record and also compromises [...]

Researchers at the University of São Paulo (USP) in Brazil have discovered that two osteoporosis drugs (etidronate and tiludronate) may combat diseases caused by iron accumulation in the body. In tests conducted on human cells, the drugs bound to excess iron, reduced oxidative stress, and prevented cell damage. The study was published in the journal BioMetals . “Currently, only three drugs are approved to treat iron overload, known as chelators. They bind to the metal and thus facilitate [...]

Researchers at the Ribeirão Preto Blood Center and the Center for Cell-Based Therapy ( CTC ) conducted a study using the NK-92 cell line to test new models of chimeric antigen receptors (CARs) with specific costimulatory domains, such as 2B4 and DAP12. The tests showed that these components helped make the cells “ready to attack,” thereby increasing their ability to destroy tumors. The results were published in the journal Frontiers in Immunology . The CTC is one of the Research, [...]

To find new ways to shield hair from heat, sunlight and air pollution, researchers in Brazil are turning to vegan-friendly ingredients for shampoos and conditioners. Published in ACS Omega , early tests show that a fruit-algae combination added to haircare products coats strands with a protective film. Although the botanical film makes hair slightly less elastic, it improves shine and makes locks easier to comb compared to hair washed and conditioned with products not containing the [...]
