Scientists Discover New Frog Species in the Amazon's Flooded Forests
Publicado em 17 de setembro de 2026
Identified in western Acre, Adenomera varcena reveals a hidden diversity that could be confirmed only through call and DNA analyses.
Identified in western Acre, Adenomera varcena reveals a hidden diversity that could be confirmed only through call and DNA analyses.
Scientists from Brazil and other countries have discovered a new species of frog in the flooded forests of the western Amazon. They named it Adenomera varcena. This finding significantly advances our understanding of Amazonian [...]

Soil bacteria protect wheat from pathogenic fungus
Publicado em 25 agosto 2026Their study, published in the journal NPJ Biofilms and Microbiomes, paves the way for the development of inoculants that can be used in agriculture. Their study, published in the journal NPJ Biofilms and Microbiomes, paves the way for the development of inoculants that can be used in agriculture. “We selected three bacteria from a group we had isolated in a previous study that showed the greatest potential to improve plant growth and exert an antagonistic effect against the pathogen.

Study Reveals How Giant Trees in Tropical Forests Transport Water to Their Uppermost Branches
Publicado em 06 julho 2026The study published in Science helps us understand the role of this little-studied type of vegetation in climate change. The study published in Science helps us understand the role of this little-studied type of vegetation in climate change. One percent of the tallest trees store more than half of the carbon in tropical forest ecosystems. The giant trees of tropical forests are important allies in the fight against climate change due to their ability to store carbon, yet they are still [...]ver notícia -
The Impact of Global Warming on Fish Reproduction May be Temporary
Publicado em 25 junho 2026In many fish species, water temperature determines the sex of the fry. In many fish species, water temperature determines the sex of the fry. This biological mechanism threatens to wipe out entire populations due to a shortage of females in the face of global warming. However, an international study conducted in Spain, France, and Brazil found that this well-known masculinization effect can be offset over generations. In a ten-year experiment involving more than 3,000 European seabass [...]ver notícia -
Longer Droughts and Changes in Rainfall Are Already Occurring in the Amazon, Research Indicates
Publicado em 28 maio 2026According to two recently published studies led by scientists from Brazil's National Institute for Space Research (INPE), the Brazilian Amazon is already beginning to experience scenarios previously projected for the coming decades, including longer dry seasons and changes in rainfall patterns.

Fires, Droughts, and Windstorms Reduce the Diversity of Amazonian Vegetation
Publicado em 24 abril 2026Even after fires, severe droughts, and windstorms, the vegetation in degraded Amazonian forests demonstrates a high capacity for regeneration, including tree species. Even after fires, severe droughts, and windstorms, the vegetation in degraded Amazonian forests demonstrates a high capacity for regeneration, including tree species. However, recovery occurs under new ecological conditions, resulting in a loss of diversity and increased vulnerability to new disturbances. On April 20, [...]ver notícia -
Solar Hydrogen Can Now Be Produced Efficiently Without the Scarce Metal Platinum
Publicado em 09 janeiro 2026A research team led by Chalmers University of Technology, Sweden, have presented a new way to produce hydrogen gas without the scarce and expensive metal platinum. A research team led by Chalmers University of Technology, Sweden, have presented a new way to produce hydrogen gas without the scarce and expensive metal platinum. Using sunlight, water and tiny particles of electrically conductive plastic, the researchers show how the hydrogen can be produced efficiently, sustainably and at low [...]ver notícia -
'Almost Half of the Beaches Will Disappear by the End of the Century,' Warns Researcher
Publicado em 27 novembro 2025Beaches around the world are undergoing a process known as “coastal squeeze” due to a combination of rising sea levels caused by climate change and urbanization in coastal areas. Beaches around the world are undergoing a process known as “coastal squeeze” due to a combination of rising sea levels caused by climate change and urbanization in coastal areas. This phenomenon not only profoundly affects the biodiversity living on the sand, but it also harms activities such as fishing [...]ver notícia -
Study Identifies Great Potential for Forest Restoration in Urban Fringe Areas
Publicado em 24 novembro 2025A study conducted at the University of São Paulo (USP) by researchers from the Nucleus of Analysis and Synthesis of Nature-Based Solutions (BIOTA Synthesis), a FAPESP Science Center for Development (SCD), identified approximately 410,000 hectares in the state of São Paulo, Brazil, with potential for forest restoration in urban fringe areas. These peripheral areas of urban centers are characterized by diverse land uses, such as residential neighborhoods, agricultural land, [...]ver notícia -
Study Assesses Livestock Vulnerability to Climate Change
Publicado em 01 outubro 2025With a pioneering, comprehensive approach on a global scale, Brazilian researchers have developed a methodology that allows them to project the physiological responses of herds of different production animal species to the impacts of climate change between 2050 and 2100.
