Outbreaks at two care homes in São Paulo state (Brazil) show that even people who have been vaccinated with one dose of the AstraZeneca vaccine or two doses of CoronaVac can transmit the virus. The cases were asymptomatic or mild and did not require hospitalization, but underscore the importance of rapidly vaccinating the entire population while continuing to require face coverings and social distancing even for those who have been vaccinated.
Meta-analysis by researchers at the Federal University of São Paulo in partnership with universities in Spain and Chile supports the idea that muscle strengthening can not only reduce cancer incidence and morality but also yield even greater benefits when it is associated with aerobic activities.
The molecule described by Brazilian researchers in the journal Scientific Reports acts on different sugars present in several sources of plant biomass, making it attractive to other industries as well.
With FAPESP’s support, Cellco created a novel process to produce enzymes used in DNA manipulation in vitro, including cloning, sequencing and mutagenesis, among other techniques, with applications in medical diagnostics and forensic analysis based on genetic material.
In non-resistant pacu, infection by Aeromonas hydrophila causes hemorrhagic septicemia, whose symptoms include reddened fins, skin lesions and bleeding, often followed in a few hours by death.
A webinar held by FAPESP featured researchers from Brazil and Germany whose findings offer clues as to how SARS-CoV-2 invades the central nervous system and which cells are most affected.
Brazilian researchers coupled the molecule with a protein that binds to SARS-CoV-2. The presence of antibodies against the virus in the sample is confirmed by light emission.
Action to reduce greenhouse gas emissions by subnational governments could help countries achieve their climate targets and contribute to the post-pandemic economic recovery, experts suggested at an event hosted by FAPESP.
Two plants frequently found in the North of Brazil could become alternatives to sugarcane as raw materials for the production of second-generation ethanol and bioelectricity, according to studies by Brazilian researchers.
The study shows that the phenomenon can be produced by means of adiabatic compression, without any exchange of heat with the environment. The process aligns the spins of the material’s particles and magnetizes the system.
If greenhouse gas emissions continue at the current level, the average temperature will tend to rise by as much as 4 °C in some regions. Under this scenario, extreme weather events will be more intense and frequent, according to projections made using the IPCC’s new climate models.
Based on data for 344 volunteers, Brazilian researchers compared the physical and mental health benefits of workouts led in person by a fitness instructor, unsupervised online sessions, and classes supervised remotely via video call. Gradually increasing intensity was associated with improvements in mental health.
Study at the Federal University of São Paulo developed a recipe combining chickpea flour and psyllium, a plant-derived soluble fiber. The product is nourishing and rated highly by consumers in qualitative surveys.
Non-invasive method uses samples of saliva or other body fluids. The diagnosis can be obtained by means of computational techniques for visualizing data and machine learning.
