The most abundant electric fish are found from the bottom of large rivers to igarapés, where they can bury themselves in the sand or blend into the leaf litter. In two weeks, an expedition in the Negro River basin collected 27 species of the group.
One of the fishing methods used to collect electric fish in the DEGy Negro River Expedition was employed for the first time on a large scale in freshwater during the Calhamazon project, which brought together researchers from Brazil and the United States between 1993 and 1996.
In tests involving animals, nanoparticles containing substances already approved for human use reduced inflammation in the biological microenvironment where malignant tumors flourish and facilitated the action of the immune system.
Researchers detected SARS-CoV-2 in male reproductive cells under the microscope even when PCR testing failed to detect the virus in semen. The discovery serves as a warning of possible implications for natural conception and particularly for assisted reproduction.
A startup supported by FAPESP is developing a system to assure the proper use of elements capable of guaranteeing structural integrity at high temperatures while reducing heat transfer from machinery and equipment to the environment.
In the fourth 2024 FAPESP Lecture, Carlos Jaramillo, a Colombian geologist, palynologist and paleobiologist affiliated with the Smithsonian Tropical Research Institute (STRI) in Panama, showed how South America’s landscapes and biomes have evolved over geological time.
In a study involving mice, scientists used a technique that combines light stimulation and bioengineering to activate a cluster of nerve cells deep inside the brain. The discovery could pave the way to future treatment of eating disorders.
In experiments with mice, researchers at the State University of Campinas (UNICAMP) in Brazil and the Pasteur Institute in Lille (France) found that viral load and inflammation decreased in animals infected by influenza virus when they were given the substance.
Center for Carbon Research in Tropical Agriculture
Today’s key issues, such as artificial intelligence, climate change, cancer and Brazilian institutions, will be the focus of inter-institutional and multidisciplinary teaching and research; the new organization gives groups more autonomy and agility.
Center for Research on Biodiversity Dynamics and Climate Change
The first Research, Innovation and Dissemination Center (RIDC) hosted by São Paulo State University (UNESP) will promote innovation focusing on sustainable solutions and accelerated knowledge dissemination.
Obesity and Comorbidities Research Center
In an article published in Nature Metabolism, researchers based in Brazil and Mexico analyze the Latin American obesity epidemic from a broad perspective that includes socioeconomic, cultural and epigenetic factors. For the authors, solutions must focus on collective action rather than individualization of the problem.
Human Genome and Stem-Cell Research Center
Through experiments with human cells and animals, researchers from the University of São Paulo and collaborators have shown how gene-environment interactions during the craniofacial development of the embryo can lead to malformations.
In a study with 49 participants, researchers at the State University of Campinas found that daily consumption of a dietary supplement containing 15 g of the substance for five weeks improved glucose metabolism even after meals.
Chemical analysis of stalagmites in the Peruaçu Caves National Park showed that global warming has disrupted the hydrological cycle in Brazil’s central region, making a significant proportion of any rain that falls evaporate before it can penetrate the soil.
Center for Research on Redox Processes in Biomedicine
Researchers at a FAPESP-supported research center showed that the addition of bromine to extracellular matrix proteins is a physiological modification dependent on the enzyme peroxidasin – the study extends knowledge of the scope of this enzyme’s activity in the mammalian organism.
