Even the smallest pollution particles change the rainfall regime in the Amazon
Publicado em 04 de fevereiro de 2022
Even the finest particles of pollution influence the process of cloud formation and the rainfall regime. A study conducted in Manaus, the capital of Amazonas state in Brazil’s North region, shows that oxidation leads small aerosols expelled by factories and car exhausts, for example, to grow very rapidly, reaching up to 400 times their original size, and that this affects raindrop formation.

Citizen Scientists Help Assure Quality of Coastal Biodiversity Monitoring
Publicado em 21 outubro 2021In 2019, history student Rodrigo Gomes found out on social media about a call for volunteers to take part in a scientific project relating to the ocean and conducted by the Federal University of São Paulo’s Institute of Marine Sciences (IMAR-UNIFESP) in Santos, on the coast of the state of São Paulo, Brazil. He signed up for the project, took workshops, and trained in the field. “I was very fortunate to have all that contact with professors and learned a great deal [...]ver notícia -
Climate Change Will Alter Functioning of Marine Microbial Communities, Study Shows
Publicado em 14 outubro 2021A study by an international group of researchers shows that interaction between communities of plankton – microorganisms that live at the bottom of the food chain in the oceans and supply most of the planet’s oxygen – will be affected by climate change in different ways depending on location.

Concepts from physics explain importance of quarantine to control spread of COVID-19
Publicado em 23 junho 2021Mathematical models that describe the physical behavior of magnetic materials can also be used to describe the spread of the novel coronavirus that causes COVID-19. Mathematical models that describe the physical behavior of magnetic materials can also be used to describe the spread of the novel coronavirus that causes COVID-19. This is the conclusion of a study conducted in Brazil by researchers affiliated with São Paulo State University (UNESP) in Rio Claro and Ilha Solteira and [...]ver notícia -
Experiments Simulate Possible Impact of Climate Change on Crabs
Publicado em 15 junho 2021Albeit very small, with a carapace width of only 3 cm, the Atlantic mangrove fiddler crab Leptuca thayeri can be a great help to scientists seeking to understand more about the effects of global climate change. In a study published in the journal Estuarine, Coastal and Shelf Science, Brazilian researchers supported by FAPESP show how the ocean warming and acidification forecast by the end of the century could affect the lifecycle of these crustaceans. Embryos of L. thayeri were exposed [...]ver notícia -
Research identifies climate-change refugia in dry-forest region
Publicado em 26 maio 2021Several indicators point to the adverse impacts of climate change on the planet’s vegetation, but a little-known positive fact is the existence of climate-change refugia in which trees are far less affected by the gradual rise in temperatures and changing rainfall regimes. Climate-change refugia are areas that are relatively buffered from climate change, such as wetlands, land bordering water courses, rocky outcrops, and valleys with cold-air pools or inversions, for example. A study [...]ver notícia -
Forest fires drive expansion of savannas in the heart of the Amazon
Publicado em 04 maio 2021White-sand savannas are expanding in the heart of the Amazon as a result of recurring forest fires, according to a study published in the journal Ecosystems. White-sand savannas are expanding in the heart of the Amazon as a result of recurring forest fires, according to a study published in the journal Ecosystems. The study was supported by FAPESP, and conducted by Bernardo Monteiro Flores, currently a postdoctoral fellow in ecology at the Federal University of Santa Catarina (UFSC) in [...]ver notícia -
High-Fiber Diet May Play a Role in Controlling the Inflammation Associated With COVID-19
Publicado em 31 março 2021A study conducted at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, shows that compounds produced by gut microbiota (bacteria and other microorganisms) during fermentation of insoluble fiber from dietary plant matter do not affect the ability of the novel coronavirus SARS-CoV-2 to enter and replicate in cells lining the intestines. A study conducted at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, shows that compounds [...]ver notícia -
Urban Growth in São Paulo Creates Distortions Between Providers and Receivers of Ecosystem Services
Publicado em 31 março 2021In Brazil, researchers are puzzling over socioeconomic and environmental indicators that do not add up. They are concerned with what they call the São Paulo Macrometropolitan Area, a mega-region comprising five metropolitan areas in the state of São Paulo with a total of 180 municipalities, some of which provide ecosystem services while others receive them. The problem is that the former, which provide the others with water, food and power generation inputs, suffer from steep [...]ver notícia -
