The mechanism by which defense cells respond to infection by Mayaro virus has been described by a team affiliated with the Center for Research on Inflammatory Diseases - CRID in an article published in the journal PLOS Pathogens. According to the authors, by establishing an experimental model of Mayaro fever in adult mice and identifying the processes involved in the immune response, the study provides a basis for the development of drugs against this disease. CRID is one of the Research, [...]

Researchers from the University of São Paulo (USP) in Brazil have developed a strategy for treating the most aggressive type of brain cancer in adults that combines a photoactive molecule and a chemotherapeutic agent - both encapsulated in protein-lipid nanoparticles. Results of the research, supported by São Paulo Research Foundation - FAPESP, were presented during the FAPESP Week France symposium, by Antônio Claudio Tedesco, of the Center for Nanotechnology, Tissue [...]

More than half the world's population runs the risk of contracting infectious diseases transmitted by mosquitoes in the next few years. With climate change, these so-called arboviruses - once a problem concentrated in the planet's tropical regions - appear to also be occurring in places with a temperate climate. "Recent studies indicate that the bacteria present in the intestine of vector mosquitoes contribute to the adaptive potential of these insects. It is therefore important [...]

The impact of the soil microbiota on the mitigation of greenhouse gases in tropical forests was the topic of a lecture given by Tsai Siu Mui, a professor and vice-director at CENA-USP. As the researcher reiterated, greenhouse gases retain the thermal energy reflected by the Earth's surface. However, in soils of tropical forests, such as the Amazon, elements such as methane and nitrous oxide are actively recycled through biogeochemical processes. "This was demonstrated by measuring [...]

In the search for new drugs to treat neglected diseases and malaria, researchers at the University of Campinas (UNICAMP) and University of Sao Paulo (USP) will assemble a team of scientists in a global collaboration network co-funded by the São Paulo Research Foundation (FAPESP), the Drugs for Neglected Diseases initiative (DNDi) and the Medicines for Malaria Venture (MMV). The international consortium, supported by São Paulo Research Foundation - FAPESP under the auspices of its [...]

In the last two years, almost 30,000 families have been removed from their homes in São Paulo Metropolitan Area (SPMA), Brazil, and the homes of more than 170,000 are under threat. The data come from the Removals Observatory, a project coordinated by Labcity at the School of Architecture and Urbanism of the University of São Paulo (USP), in partnership with the Federal University of the ABC (UFABC) and the Federal University of São Paulo (UNIFESP). The collaborative [...]

The second law of thermodynamics states that the total entropy of an isolated system always tends to increase over time until it reaches a maximum. In other words, disorganization increases without outside intervention. Even the best electrical equipment inevitably heats up, as part of the energy that should be converted into mechanical work is dissipated in the form of heat, and supposedly inanimate objects deteriorate as time progresses but do not spontaneously regenerate. However, this [...]

The burning of sugarcane, carried out to eliminate dry leaves before harvesting, for years altered the air quality in the central region of the State of São Paulo, Brazil. The particles launched into the atmosphere during the process were visible to the region's inhabitants and were deposited in the streets and on cars. Atmospheric pollution also caused respiratory problems among the population, impacts on biodiversity and the native vegetation, and contaminated [...]

One of the speakers at FAPESP Week France, held in Lyon and Paris until November 27th, Livia Freire, a researcher at the Institute of Mathematical and Computing Sciences of the University of São Paulo (ICMC-USP), has been developing computer simulations to try to broaden the knowledge on the transport of aerosols. "Our interest lies in knowing how these particles are transported by atmospheric flows, which are very complicated movements to simulate and understand, because they are [...]
