IBGE estimates production of 328 million, 12% more. The figures for March [...]ver notícia -
Microplastics contaminate protected marine areas in Brazil
Publicado emBrazilian and Australian scientists evaluated particle volume using oysters, shellfish and mussels in ten reserves Not even protected marine areas (AMPs) – areas with various restrictions on human activity – are free from microplastic contamination in Brazil. This is what shows a study by Brazilian and Australian scientists and published in the magazine Environmental Research. By international classification, microplastics can be up to five millimeters in diameter, [...]ver notícia -
135,000 years ago, humans had developed a key component of universal culture: language
Publicado emA way of thinking about thousands of languages spoken by humanity is to visualize them as branches of a tree, thus drawing the evolution of these languages over time. If we move forward in time, we will see the diversification of some languages and the death of others. If we invest the time needle we can see the branch or the common trunk that joins some languages with others. For example, if we draw the history of Galician and Romanian, we will see in Latin the [...]ver notícia -

Second smallest vertebrate in the world is Brazilian – and it fits on a coin
Publicado em 29 outubro 2024Brazilian researchers have described the second smallest vertebrate in the world, a frog measuring less than 7 millimeters found in Ubatuba, on the north coast of São Paulo. A species of the same genus had already been located in southern Bahia – and it was even smaller. The article reporting the discovery was published this month in the journal PeerJ. Flea frog Brachycephalus dacnis found in Ubatuba (SP) measures 6.95 millimeters. Image: Lucas Machado Botelho/Projeto [...]ver notícia -
The asteroid that wiped out the dinosaurs turned ants into “farmers”
Publicado em 14 outubro 2024New research has highlighted how the asteroid impact that ended the dinosaurs helped give rise to the mutualistic relationship between ants and fungi, marking an early form of agriculture, long before humans began farming. The asteroid that wiped out the dinosaurs turned ants into “farmers” The mutualistic relationship between ants and fungi arose after an asteroid impact The asteroid impact that killed the dinosaurs 66 million years ago may have led to an extraordinary [...]ver notícia -
Microplastics end up mostly in the brain, which poses the risks
Publicado em 05 outubro 2024Microplastics are now everywhere in the human body. Wherever researchers have looked for them, there they are. The highest concentrations were found in vital organs such as the brain, but also the placenta and the cardiovascular tree. For example, in the brain, the levels of micro- and nanoplastics detected in an average-weight adult brain correspond to the equivalent of a third of a 1.5-liter plastic bottle. This is highlighted by research commissioned by Vera Studio to a group of experts [...]ver notícia -
Microplastics can reach the brain through the nose; find out more
Publicado em 03 outubro 2024Microplastics are everywhere, including in humans. Previous work has already shown how particles can enter our bodies in three ways: through ingestion, breathing or absorption through the skin – and, from there, reach other parts of the body. A recent study showed that microplastics can also reach the brain. And the gateway could be the nose. The discovery refutes the idea that the central organ of the nervous system is isolated from the rest of the body and that the blood-brain [...]ver notícia
