The Chagas disease parasite (Trypanosoma cruzi) undergoes a major transformation throughout its life cycle in order to infect humans and other mammals. It alters the types and amounts of proteins in its body to adapt. The factors that drive this transformation are still poorly understood. In May, a study was published in the journal PLOS Pathogens revealing that part of this process involves chemical changes in transfer RNA (tRNA). This molecule acts as a cellular "delivery person," [...]

Researchers from the Brazilian Agricultural Research Corporation (EMBRAPA) and the University of São Paulo (USP) described the role of three bacteria in suppressing a soil-borne wheat pathogen that causes root rot. 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 [...]

Low concentrations of caustic soda (sodium hydroxide, NaOH) are more efficient than high doses for preparing organic waste for biogas production. This finding increases methane production, reduces reagent consumption and, consequently, diminishes process costs and minimizes the risk of inhibiting the microorganisms responsible for the process. The raw material for the study that reached such a conclusion was the banana – its peels and parts unfit for sale collected from wholesale [...]

According to a study conducted by Brazilian scientists and published in the journal NPJ Biodiversity, most of the new mammal species described over the past 35 years are housed in institutions in countries of the so-called Global North, even though the vast majority of them were discovered in poor or developing countries in the Southern Hemisphere. The study analyzed 1,116 new mammal species described between 1990 and 2025. It concluded that 95% of the species were native to the Global [...]

In May, a study was published in Nature Communications that identified an unusual regime of quantum oscillations in a three-dimensional topological insulator. The results show that, when subjected to temperatures near absolute zero and extreme magnetic fields, electrons in the material zirconium pentatelluride (ZrTe₅) exhibit behavior that deviates from the pattern predicted by conventional theory. The study, led by researchers from the University of São Paulo (USP) in Brazil, the Los [...]

Brazilian researchers exposed newborn rats to cigarette smoke for five minutes, twice a day, starting on the second day of life. When the experiment ended 26 days later, they pulled the animals' teeth and photographed them. The exposed animals' incisors looked slightly yellower than the controls', but there were no chips, no opacities, and no missing structures. By the standard a dentist would apply in a clinic, nothing was wrong. Only when the team ran the enamel through [...]

A study involving more than 58,000 adolescents from 21 countries found that "unstructured free time" – defined as periods without adult supervision or activities guided by educational, cultural, or athletic goals – is strongly associated with delinquent behavior and exposure to violence among young people. The study was published in May in the journal PLOS ONE by researchers affiliated with the International Self-Report Delinquency Study (ISRD) consortium, which brings together teams [...]

A combination of omega-3 and low-dose acetylsalicylic acid (ASA) produced results comparable to antibiotics in treating severe periodontitis. This conclusion is based on a study conducted by researchers affiliated with Albert Einstein Israelite Hospital, Guarulhos University (UNG), the University of Taubaté (UNITAU), and the Ribeirão Preto School of Dentistry at USP (FORP-USP) in Brazil, as well as Harvard University in the United States. The findings were published in the Journal of [...]
