Researchers at the University of São Paulo (USP) in Brazil have discovered 45 new toxins produced by Salmonella bacteria, some of which are associated with foodborne infections. The study was conducted at the Center for Research in Bacterial and Bacteriophage Biology (B3 RIDC) and was published in the journal PLOS Biology. It shows that these substances primarily act in the competition among microorganisms for space and resources. The study also suggests that these substances may [...]

The fungus that causes sporotrichosis is typically transmitted among cats and results in serious lesions. Recently, it was found in the internal organs of wild animals. The study, supported by FAPESP, was published in March in the journal Mycopathologia. Three species were detected, all of which are in the genus Sporothrix. One of these species, S. brasiliensis, is endemic to Brazil. In addition to S. brasiliensis, S. globosa and S. schenckii were found; the latter is predominant and has [...]

Researchers at the Center for Sustainable Management of Pests, Diseases, and Weeds (CEMASU) , one of the Science Centers for Development ( SCDs ) funded by FAPESP in the state of São Paulo, Brazil, used a biopolymer to encapsulate and extend the storage life and release rate of a bioinsecticidal fungus. The study was published in the scientific journal ACS Omega. The goal is to extend the shelf life of Beauveria bassiana, a fungus widely used as a bioinsecticide on various [...]

The wetlands and veredas of Brazil's Cerrado savanna-like biome can store up to 1,200 tons of carbon per hectare. This is about six times the biomass stock of typical Amazonian forests. Dating indicates that this carbon has, on average, been in place for 11,000 years and, in some cases, as long as 20,000 years. This is the result of a slow accumulation process favored by the lack of oxygen in water-saturated soils. The findings come from a study published in the scientific journal [...]

A pioneering study has uncovered a unique genetic characteristic in sloths that could unlock secrets to healthy ageing and metabolic efficiency, with potential implications for human health and even long-duration space travel. In a scientific first, researchers have successfully sequenced and analysed the genome of the tree-dwelling mammal, identifying specific "jumping genes" – DNA sequences capable of relocating within the genome – that have been remarkably preserved [...]

In the coming weeks, the Human Genome and Stem Cell Research Center (HUG-CELL) will begin recruiting participants for the "Our Genes" project. The initiative aims to identify couples at an increased risk of transmitting recessive genetic disorders, where a child inherits two altered copies of the same gene, one from each parent, as well as Fragile X syndrome, a common cause of intellectual disability that is passed down through families. The work will be carried out in partnership with the [...]

Unifesp's Institute of Marine Sciences Leads Coastal Research Efforts The Universidade Federal de São Paulo, known as Unifesp, has established itself as a key player in Brazilian marine science through its Institute of Marine Sciences, or IMAR-UNIFESP, located in Santos on the coast of São Paulo state. Researchers there focus on long-term monitoring of coastal environments, combining academic expertise with community involvement to track biodiversity changes. One notable [...]

A species of moth that was first described in 1818 was believed to be a single species. However, it has since been discovered that it is actually a complex of species, eight of which are found in Brazil. These findings are the result of a study that integrated molecular techniques, morphological data, and the identification of host plants from populations in the Amazon, Atlantic Forest, and Pantanal regions. The study was published in the journal Scientific Reports by researchers from [...]

Box jellyfish are often feared as dangerous animals, with some species capable of causing severe or even fatal stings. However, box jellyfish nematocysts – organelles responsible for this toxic sting – are theorized to also play an unexpected role in reproduction. While many studies focus on researching the range of toxicity levels exhibited by the over 50 species of box jellyfish, their reproductive process is poorly understood. In this study, a research team examined reproductive [...]
