Corn farming sustained large pre-colonial villages in the Brazilian savanna
Publicado em 14 de outubro de 2026
According to a study published in the journal Science Advances , corn cultivation was essential for the subsistence and development of large villages inhabiting the Cerrado – Brazil’s savanna biome – between the 9th and 17th centuries. The research, led by archaeologists from the University of São Paulo and supported by FAPESP, reveals the subsistence strategies of these densely populated communities for the first time. They employed sophisticated land-use practices involving the [...]

Strength training causes fat cells to shrink even before weight loss
Publicado em 22 setembro 2026Just seven days of strength training increased visceral fat burning in obese mice, even before any weight loss could be seen on a scale. In an experiment conducted at the State University of Campinas (UNICAMP), researchers observed that a short period of strength training activated mechanisms involved in fat breakdown, reduced fat cell size, and decreased fat around the animals’ intestines. The study, published in the journal Life Sciences , aimed to understand how adipose tissue responds [...]ver notícia -
New technique identifies stars that have swallowed planets
Publicado em 09 setembro 2026An international team led by researchers from the University of São Paulo (USP) in Brazil has developed an innovative method to identify stars that have consumed the planets around them. The technique detects variations in the abundance of beryllium, a relatively rare chemical element, and could open a new window into studying the evolution of planetary systems. The study, published in the journal Astronomy & Astrophysics , analyzed a binary system consisting of two very similar stars, both [...]ver notícia -
Traces of nearly four million coins reveal how Rome achieved economic integration
Publicado em 03 setembro 2026For 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 [...]ver notícia -
Increasing daily steps is as effective as aerobic exercise in managing asthma
Publicado em 02 setembro 2026For 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 flexible, [...]ver notícia -
Although research on animal production and climate is growing, bringing science to the field remains challenging
Publicado em 25 agosto 2026Climate 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 analyzed [...]ver notícia -
Soil bacteria protect wheat from pathogenic fungus
Publicado em 21 agosto 2026Researchers 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 [...]ver notícia -
Air pollution induces changes in the oral mucosa and worsens periodontal disease
Publicado em 19 agosto 2026Air pollution can affect oral health. A study conducted in Brazil by researchers from São Paulo State University (UNESP) and the University of São Paulo (USP) demonstrated for the first time that exposure to fine particulate matter (PM2.5), a main component of urban air pollution, causes changes in oral tissues and accelerates the destruction of periodontal tissues that support teeth. The study was supported by FAPESP and the results were obtained by exposing mice to polluted air collected [...]ver notícia -
Artificial intelligence acts as an ‘ideological chameleon’ and may deepen political polarization, study finds
Publicado em 18 agosto 2026Researchers at the State University of Campinas (UNICAMP) in the state of São Paulo, Brazil, examined the ideological stance of large language models – artificial intelligence systems trained to understand and generate human language – and discovered that when informed of a user’s political views, they tend to mirror those views. According to the researchers, this behavior could exacerbate political polarization in Brazil. The political influence of these tools does not necessarily [...]ver notícia -
Most mammal species discovered in the South since 1990 are found in the North
Publicado em 17 agosto 2026According 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 [...]ver notícia
