Hot weather and air pollution may create a especially hazardous combination for older adults at risk of stroke, research from Brazil suggests. The findings point to a connection between environmental conditions and sudden interruptions in blood flow to the brain. scientists reported that strokes were more likely around periods when heat waves and particulate pollution occurred together. Their analysis adds to efforts to understand how the places people live can influence brain health [...]

Studies 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 [...]

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, [...]

Researchers at the University of São Paulo (USP) in Brazil and their international collaborators have created a computational model that can generate a "digital twin" of the human thorax. The goal is to personalize the treatment of respiratory diseases using a special type of light. Described in a paper published in PNAS, the journal of the U.S. National Academy of Sciences, the new technology uses CT scans to predict the path that light radiation will take inside the body. This makes it [...]

SAO PAULO, Oct. 22 (Xinhua) -- In 2010-2024, Brazil's Amazon emitted an annual average of 1.17 billion tons more carbon dioxide than it absorbed, according to a study published on Thursday by the Sao Paulo Research Foundation. The imbalance is adding to global warming and eroding the rainforest's role as the planet's most important tropical climate regulator. The study, also published in the British scientific journal Nature, showed fires released approximately 1.47 billion [...]

One 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 [...]

A 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 [...]

A 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 [...]
