Researchers isolated a strain of Pseudomonas alcaligenes that can withstand temperatures as high as 44 °C from a hot spring in Chile, and characterized the substances produced by the bacterium that help it survive extreme conditions.

An estimated 800 million people's food and income are threatened by rapidly spreading cassava diseases. But in good news for cassava breeders and farmers, breakthrough research has established the pathogens and the first diagnostic tests for two diseases: Cassava Frogskin Disease and Cassava Witches’ Broom Disease. This achievement can revolutionize cassava disease management across Latin America and the Caribbean as well as Southeast Asia, where farmers and researchers have been working side-by-side to fight the spread of these diseases for decades.

A study published in Nature Climate Change predicts that 36% of anurans’ habitats worldwide will soon be threatened by a combination of rising temperatures and water scarcity. Brazil has the greatest diversity of anurans in the world and some of the most vulnerable anuran habitats.

Scientists have organized structural barriers to food systems change into a comprehensive framework, with the aim of empowering policymakers, civil society organizations, and researchers to tackle food sustainability challenges more effectively.

The researchers synthesized a molecule inspired by a substance present in Nectandra leucantha (canela-seca or canela-branca). Animal trials have produced promising results.

School addresses the connections between academic research and reparation processes, recognizing the relevant role of the university in promoting the right to memory and social reparation initiatives. Registrations are due on January 27, 2025.

Plant collections are full of surprises. It may take decades to id plant samples, but it’s worth the effort, especially when some of these species are not known from anywhere else on Earth.

Researchers tested the effects of the plant’s methanolic extract and an isolated alkaloid substance, palmatine, on mice. The results were promising.

Land use and land cover (LULC) analysis has become increasingly significant in environmental studies due to its direct impact on the environment. Changes in LULC affect the ecological and climatic balance, in addition to increase the terrain’s susceptibility to hazardous phenomena. However, one of the key challenges in analyzing LULC time series is the presence of classification errors, which can result in invalid transitions. Invalid transitions, which represent unlikely or impossible land cover changes in a given period, can lead to misinterpretations of causes or consequences of hazard events, especially in highly susceptible areas, such as mountainous regions.
