Researchers at the Brazilian Center for Research in Energy and Materials (CNPEM) have developed microscopic technology that can grow cells in three dimensions (3D). The goal is to conduct toxicity tests on new products by more accurately simulating living organisms. This technology is a breakthrough for drug development, material safety assessment, and ecotoxicology research (the study of the impact of substances on ecosystems). It also helps reduce the need for animal testing. The device [...]

For centuries, the study of ancient history relied primarily on interpreting classical texts and examining inscriptions and archaeological remains at their sites of origin or in museums. In recent years, however, a little-known transformation has profoundly changed this landscape. The digitization of extensive archaeological collections, coupled with the development of quantitative methods that can integrate millions of scattered records, is ushering in a new era of historical research. Like [...]

A combination of omega 3 supplements and low dose aspirin performed about as well as a standard antibiotic regimen in patients with severe gum disease, according to a year long randomized trial published in May in the Journal of Periodontology. About 58 percent of patients treated with antibiotics reached the study's clinical target. In the omega-3 and aspirin group, 57.7 percent did. Both substantially outperformed the comparison group. Among patients who received the standard deep [...]

For people with moderate to severe asthma, increasing the number of daily steps may be as effective as structured aerobic training sessions for managing the disease. This finding comes from a study led by researchers at the University of São Paulo (USP) and published in the journal Pulmonology. The study demonstrated that both approaches improve quality of life, alleviate symptoms of anxiety and depression, and control asthma in the medium term. This offers doctors and patients more [...]

Capuchin monkeys hunt prey when fruits and vegetables become scarce, potentially mirroring the habits of human ancestors, according to a study published August 26, 2026 in the open access journal PLOS One by Susana Carvalho (Gorongosa National Park, Mozambique), Noemi Spagnoletti (Sapienza University of Rome, Italy) and colleagues. Humans are the only living primates who regularly hunt animals larger than themselves, a lifestyle thought to have emerged alongside large brains and complex [...]

Climate change is reshaping global livestock production systems and leading to increased research on the topic. However, science still faces the challenge of translating advances in knowledge into practical solutions for the field and public policy. This is one of the main conclusions of a study published in the journal Tropical Animal Health and Production by researchers from the Luiz de Queiroz College of Agriculture at the University of São Paulo (ESALQ-USP) in Brazil. The study [...]

A study published  in the journal Ecological Monographs indicates that large mammals, such as tapirs, peccaries, agoutis, and deer, alter the chemical composition of litter and soil in tropical forests of the Brazilian Atlantic Forest. As a result, they increase nutrient availability and, possibly, soil fertility. The study was conducted by members of the Center for Research on Biodiversity and Climate Change ( CBioClima ), a Research, Innovation, and Dissemination Center ( RIDC ) [...]

When a 10,000-year-old prairie is plowed up to plant corn or a savanna is consumed by a strip mall, these once-grassy expanses, if left to regrow, can eventually look vaguely like they did before. But a growing body of research suggests that what comes back isn't the same as what was lost, even decades later. And now scientists are starting to understand why. That's the takeaway of a new study of grasslands worldwide published in the journal Proceedings of the National Academy [...]
