In a groundbreaking study, researchers from São Paulo State University (UNESP) in Jaboticabal, in collaboration with the Brazilian Agricultural Research Corporation (EMBRAPA), have designed an innovative artificial intelligence tool aimed at evaluating stress levels in tambaqui, a native fish that holds the title of the most extensively farmed species in Brazil. This work is detailed in the peer-reviewed journal Aquaculture The significance of this study lies not only in the [...]

In a critical examination of Brazil's environmental policies, researchers highlight the systematic neglect of diffuse seeps—vital to water security and the formation of wetlands in the Cerrado savanna biome. Despite existing legal protections, these ecosystems remain largely overlooked by public policies, environmental consultants, landowners, and regulatory agencies. Diffuse seeps are characterized by groundwater flowing continuously across large areas, rather than emerging from a [...]

Once a harmless drifter in the Sargasso Sea, an algae known as sargassum is now flooding tropical beaches, from Brazil to the Caribbean, with stinky, toxic piles. As it rots, it releases gases like ammonia and methane, turning paradise into a health hazard. It’s bad for tourism, fishing, and marine life, and worse, most of it ends up dumped in landfills. No reuse. No recycling. Just rot. Can we turn this tide into something useful? For some time now many smart minds have been [...]

Researchers in Brazil have discovered a new species of bacteria belonging to the genus Bartonella in phlebotomine insects, commonly known as sand flies, in the Amazon National Park in the state of Para. While sand flies are usually linked to transmitting leishmaniasis, the DNA of this new bacterium shows similarities to Bartonella bacilliformis and Bartonella ancashensis, both responsible for Carrion’s disease—also called Peruvian wart or Oroya fever—in Andean [...]

In Brazil, researchers at São Paulo State University (UNESP) conducted experiments on rats and identified that a protein-deficient diet during pregnancy and breastfeeding can compromise the reproductive health of male offspring. A study published in the journal Biology Open found that maternal protein restriction causes changes in the structure and function of the epididymis, an organ in the reproductive system responsible for the maturation and storage of sperm. Following the [...]

Recent research from the University of São Paulo has revealed concerning data about the impact of deforestation on the Brazilian Amazon. The study, published in Nature Communications , quantifies how forest loss and global climate change have contributed to significant alterations in the biome, notably during the dry season. According to the findings, deforestation is responsible for approximately 74.5% of the rainfall reduction and 16.5% of the temperature increase observed in the [...]

University of São Paulo develops eco-friendly ceramic clay using sargassum, reducing coastal pollution and improving energy efficiency. Brazilian researchers have developed a ceramic clay that is lighter than that normally used in civil construction by adding algae from the Sargassum genus to the manufacturing process. These brown algae, also known as sargassum, are common in the central Atlantic Ocean. However, they have been washing up in large quantities on beaches in the [...]

A new species of bacteria from the genus Bartonella has been identified in the Amazon National Park in Pará, Brazil, specifically within phlebotomine insects, commonly known as sand flies. These insects, associated primarily with the transmission of leishmaniasis, have now become the focus of research due to the genetic similarities of this newly discovered microorganism with two Andean Bartonella species, B. bacilliformis and B. ancashensis. Both of these species are known to cause [...]

A recent study has uncovered significant evidence of osteomyelitis, a severe bone disease, in fossilized remains of sauropods, the long-necked dinosaurs that roamed the Earth around 80 million years ago. The findings, stemming from fossils discovered in Ibirá, São Paulo, Brazil, shed light on a potentially fatal health crisis for these ancient creatures. Researchers examined six individual fossils from the Cretaceous period and found clear indicators of osteomyelitis—an [...]
