Most trees in the Amazon (90%), the Atlantic Forest (90%), or the Cerrado, the Brazilian savannah-like biome (60%), depend on animals to disperse their seeds, ensure their reproduction, and keep the forest standing. Birds, mammals, fish, and even a species of amphibian play a crucial role in forest diversity around the world. However, this process has been disintegrating as populations of seed-dispersing animals have declined dramatically. The loss of frugivorous animals (whose diet [...]

The population of one species of coral in the main island of the Alcatrazes Archipelago Wildlife Refuge (REVIS), located off the southern coast of the state of São Paulo, Brazil, retains about 20 tons of carbon per year. This amount is equivalent to the carbon emissions from burning 324,000 liters of gasoline. These results come from a study published in the journal Marine Environmental Research by researchers supported by FAPESP at the Institute of Marine Science of the [...]

Biodiversity is important in every ecosystem. Research has shown having a richer diversity of plant and animal species bolsters ecosystem functioning and stability, making habitats more resilient to the threats of things like pests, disease and climate change. Still, there are varying degrees of importance. Now, research led by the University of Michigan reveals some of the real-world implications of this fact in forests, providing valuable insights for land managers and conservationists [...]

A team of physicists from the University of Sao Paulo (USP) in Brazil has introduced a new theoretical framework that could advance the search for dark matter by focusing on inelastic particles that interact with ordinary matter through a novel type of force carrier. Their study, published in the Journal of High Energy Physics, proposes a model involving a massive vector boson that enables interaction between dark and visible matter. "Dark matter constitutes roughly 27% of the universe, [...]

An international study has found tropical trees have remained minimally affected by droughts but an increase in climate change events is likely to have long-term effects on stem growth resilience. Emeritus Professor Patrick Finnegan, from The University of Western Australia’s School of Biological Sciences, was a co-author of the study led by Wageningen University & Research and published in Science. “Carbon dioxide, taken from the atmosphere through photosynthesis, is [...]

Brazilian researchers have taken an important step toward precision medicine by identifying four genes that can predict which melanoma patients will not respond to immunotherapy. Although this treatment has revolutionized the fight against melanoma, the most aggressive and lethal form of skin cancer, it is still costly and variable in efficacy, which limits its use, especially in the SUS (Sistema Único de Saúde), the country's national public health system. The goal is to use [...]

During Brazil's COVID-19 vaccination campaign, when several brands of vaccines were available and the Chinese vaccine was the most common, an unprecedented phenomenon occurred. People crossed neighborhoods or even cities in search of vaccination centers that administered a specific brand of vaccine. Photos of people getting vaccinated were posted on social media alongside proud hashtags praising the national health system, such as "Long live the SUS" (in reference to the [...]

The coelacanth is known as a "living fossil" because its anatomy has changed little in the last 65 million years. Despite being one of the most studied fish in history, it continues to reveal new information that could transform our understanding of vertebrate evolution. This is revealed in a study published in the journal Science Advances by researchers from the University of São Paulo (USP) in Brazil and the Smithsonian Institution in the United States. Upon [...]
