Overtraining affects the brain’s chemical regulation, study shows
Publicado em 30 de outubro de 2026
Excessive physical exercise affects more than just the muscles; it can also alter brain chemistry. A new study published in the journal Neuroscience revealed that exhaustive training without adequate rest alters the regulation of dopamine in the hippocampus, a brain region closely linked to memory and the regulation of emotions.
When observing mice subjected to an intense exercise routine, Brazilian researchers noted that dopamine, a neurotransmitter essential for alertness and motivation, [...]

New metabolic marker predicts longevity and risk of chronic diseases
Publicado em 29 outubro 2026Studies conducted in various countries indicate that approximately 60% of people over the age of 65 currently live with two or more chronic conditions simultaneously. With the aim of reversing this trend and promoting healthy aging, European researchers have created a new personalized indicator that provides a detailed snapshot of a patient’s metabolism by analyzing, with high precision, the chemicals the body produces to function. Presented during FAPESP Week Netherlands by Joris Deelen [...]ver notícia -
Project uses biomarkers to prevent infections and injuries in Paralympic athletes
Publicado em 29 outubro 2026During a competitive cycle, a Paralympic athlete is 20 times more likely to contract an infection and 11 times more likely to be hospitalized due to such complications than an Olympic athlete. In addition, 30% of Paralympic athletes suffer from infections in the upper respiratory tract – an area that includes the nose, mouth, and throat – compared to just 2% of Olympic athletes. Among wheelchair users, up to 30% experience recurrent urinary tract infections. To mitigate this immune [...]ver notícia -
System using drones and artificial intelligence identifies the ideal time for cattle slaughter
Publicado em 29 outubro 2026In beef cattle production, determining the ideal time to sell makes all the difference in a producer’s costs. This is because, once an animal reaches its natural growth limit, it stops gaining weight significantly. From that point on, every additional day in feedlot means spending money on feed without gaining meat in return. To identify this optimal window without having to weigh every animal in the herd on a scale – a time-consuming and stressful process for the cattle – a group of [...]ver notícia -
Crop diversification protects fields from extreme weather and boosts productivity
Publicado em 29 outubro 2026Varying crop rotations and keeping the soil constantly covered with vegetation helps protect crops against droughts and floods, in addition to increasing productivity. This technique was tested in Rio Grande do Sul state, Brazil, by researchers from the Center for Carbon Research in Tropical Agriculture ( CCARBON ) at the University of São Paulo (USP). The study compared traditional crops with areas that used “cover crops” – plants grown not for sale, but to protect and nourish the [...]ver notícia -
Platform simulates lowest-cost pathways for Brazil to achieve carbon neutrality by 2050
Publicado em 29 outubro 2026A new public, open-source digital platform developed by scientists at the State University of Campinas (UNICAMP) in Brazil and Princeton University in the United States promises to facilitate the formulation of climate policies in Brazil. Named “NetZero Brazil 2050” , the system cross-references georeferenced data on energy demand, land use, and macroeconomics to simulate carbon-neutrality scenarios. In practice, the tool calculates in real time the lowest-cost decarbonization pathways for [...]ver notícia -
Heat waves and pollution increase stroke risk in older adults, study finds
Publicado em 28 outubro 2026A study conducted in Brazil by researchers at the University of São Paulo (USP) found that each additional day spent under a heat wave in São Paulo is associated with an increased risk of acute stroke in people aged 65 and older. For the research, a heat wave was defined as at least two consecutive days with maximum temperatures of 33.1 °C or higher. This impact becomes even more critical when high temperatures are combined with air pollution from fine particulate matter (PM10) – a [...]ver notícia -
Supercurrent enables the reading of quantum information without destroying it
Publicado em 23 outubro 2026One of the fundamental challenges of quantum computing is obtaining information from a quantum bit, or qubit. Unlike a conventional bit, which can be read repeatedly without altering its content, direct measurement of a quantum system typically causes the state to collapse before it can be determined. In other words, reading the information modifies it. A new study with support from FAPESP proposes circumventing this problem by utilizing a unique property of a certain type of qubit called an [...]ver notícia -
Brazilian biobank may help personalize cancer prevention in the public health system
Publicado em 20 outubro 2026A bank of biological samples from thousands of Brazilians could help the Unified Health System (SUS), which is public and free, identify people at higher risk of developing certain types of cancer. In the future, the SUS could offer these individuals more personalized prevention and screening strategies. Developed at Hospital de Amor in Barretos, a city in the Southeast region of Brazil, the initiative collects genetic, epidemiological, and lifestyle data from people with and without cancer to [...]ver notícia -
Survey of 102 cities reveals more than 40,000 new viruses
Publicado em 14 outubro 2026A global mapping project revealed tens of thousands of previously unknown viruses circulating in environments with high human traffic, such as transit stations, hospitals, and sewage systems. The study, detailed in an article published in the journal Nature Communications , analyzed 2,922 samples collected in 102 cities across 31 countries, including São Paulo, Brazil. An international team, including Brazilian researchers, used this data to compile the UPVAtlas (Urban and Peri-urban RNA Virus [...]ver notícia
