Based on data collected in the field, Brazilian researchers showed that small and medium trees suffer most in the first two years after a fire, but the overall impact on vegetation can last decades. Carbon stocks fall 12.8% in burned areas on average.
Correlating whole-genome sequencing with epidemiological data for the city of São José do Rio Preto in Brazil, researchers show that severe COVID-19 and deaths from the disease rose sharply when the variant became prevalent in the region. A two-week lockdown and vaccination of the elderly averted a collapse of the health system.
In an article published in PNAS, researchers affiliated with Butantan Institute describe the genome of Bothrops jararaca and suggest the origin of genes responsible for toxins in its venom.
An article in Trees - Structure and Function reports findings from an analysis of 7,000 tree falls in a three-year period. Stormy weather was the main cause during the rainy season.
A study conducted at the University of São Paulo and published in Science correlates birds and plants in seed dispersal networks.
A study alerts to the conjunction between a climate change scenario and little inspection with the arrival of the dry season in the country, which favors large-scale fires – such as that which occurred in the Pantanal in 2020. To avoid further tragedies, researchers defend the implementation of a policy of integrated fire management.
A study published in Nature Medicine evaluated individuals before and after taking CoronaVac. Based on the results, researchers at the University of São Paulo’s Medical School are testing novel strategies such as suspending treatment one or two weeks before vaccination.
Researchers analyzed strategies for ecosystem conservation and rehabilitation of degraded areas in the second part of the FAPESP 60 Years Lectures.
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.
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.
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.
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.
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.
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.
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.
Developed by startup In Situ from stem cells and a hydrogel, the product is bioprinted and placed lightly on the skin.
Study shows that males of the species Manogea porracea protect spiderlings and eggs against predators even if they cannot be sure of their paternity.
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.
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.
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.
Researchers compared data for pregnant women in Rio de Janeiro and Manaus who were infected by zika virus in 2015-16. Factors that influenced the risk of fetal malformation were the high zika attack rate in the area and being infected in the first trimester of pregnancy.
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.
A project led by researchers at Getúlio Vargas Foundation in Brazil and the University of Michigan in the US produced a detailed analysis of the effects of public policies and government decisions on the response to COVID-19, highlighting the factors that influenced its success or failure in many countries and regions around the world.
The study was conducted in the city of São Paulo, with over 2,000 participants who were active or retired staff of the University of São Paulo and enrolled in the Brazilian Longitudinal Study of Adult Health (ELSA-Brazil). The researchers say the city has one of the highest prevalence rates of psychiatric disorders in the world.
The initiative is being implemented as a partnership between local government, DASA Laboratories and FAPESP.
