These factors combined have worsened the severe drought conditions in the transition zone between the eastern Amazon and the Brazilian savanna, where the main soybean-producing region (MaToPiBa) is located. The researchers who detected the trend warn that crop yields could fall.
A multicenter research team investigated an outbreak in 2019, which proved to be due to a subtype of the pathogen that causes Newcastle disease. According to the researchers, the risk to humans and poultry is low.
Patients submitted to a procedure that “resets” the immune system were tracked for a year by scientists at a FAPESP-supported research center. Their clinical improvement correlated with renewal of a group of defense cells known as B lymphocytes.
Experiments were conducted on mice by a group at the University of São Paulo. The results, reported in the journal Endocrinology, could have future implications for therapies to control body weight.
The tambaqui ranks second in Brazil in terms of fish production, behind only the tilapia. Consumers appreciate its meat, and it produces many offspring and grows fast. To conquer the global market, however, researchers argue that investment in innovation and genetic improvement is needed.
In a study conducted by researchers at the University of São Paulo involving experiments on mice, the synthetic substance not only prevented the neuropathic pain typically induced by chemo drugs but was also beneficial against cancer.
A study by researchers in Brazil and the UK reinforces the hypothesis that Drosophila melanogaster has a mutualistic relationship with Wolbachia bacteria. Their findings can help make the fight against mosquito-borne diseases more effective.
Brazilian researchers analyzed data for 2,777 patients hospitalized between January 5 and September 12, 2021. For those who had been fully vaccinated, being over 60 and having kidney failure were the sole predictors of hospitalization and death from COVID-19.
Survey by National Disaster Surveillance and Early Warning Center (CEMADEN) highlights simultaneity of extreme weather episodes due to heavy rain in North, Southeast and parts of Center-West, and drought in South and parts of Northeast.
The process is sustainable and is described by researchers at universities in Brazil and Portugal in the journal Green Chemistry. The article is one of those highlighted as “hot” by the journal’s editors and referees.
Although this variant of SARS-CoV-2 is less aggressive, the explosive growth of case numbers has again driven health services to the verge of collapse. Lack of tests and a “data blackout” at the Health Ministry make an accurate assessment of the situation impossible.
Brazilian researchers tracked 425 patients for six to nine months after hospital discharge. Over half reported memory decline, and tests showed significant cognitive impairments in the group.
A study led by Brazilian researchers measured species numbers and attributes, as well as carbon dynamics, in two areas of the Brazilian savanna – one is regularly burned and no fires have occurred in the other for 16 years.
The wearable device has screen-printed sensors on three fingers to detect the presence of toxic substances in fruit and vegetables. Prior preparation of samples is not required, and no waste is generated.
An article in the Journal of Medical Virology by researchers affiliated with the Federal University of São Paulo in Brazil argues that this is the reason for the relatively small proportion of severe cases and deaths among vaccinated patients despite omicron’s greatly increased transmissibility.
Detection of high-frequency gravitational waves would offer knowledge of phases of the early Universe not accessible to investigation based on electromagnetic waves, potentially paving the way to a new physics beyond the Standard Model.
Women who were poor as children are more likely to develop mental health disorders, such as attention deficit and hyperactivity; the study assessed 1,590 schoolchildren for some seven years.
The new Engineering Research Center will be led by scientists affiliated with the University of Campinas’s Interdisciplinary Center for Energy Planning, in partnership with colleagues at universities and research institutions in the state of São Paulo, Brazil.
Research conducted at São Paulo State University (UNESP) in Brazil showed that the technique inhibits bacterial activity and can be used in the consulting room.
A randomized, double-blind, placebo-controlled clinical trial conducted by the University of São Paulo found that a vaccine taken sublingually for 18 months had positive results, reducing skin lesions and itchiness.
Researchers have found that nanoparticles resulting from human activities such as the burning of fossil fuels rapidly grow in the atmosphere and influence cloud formation. The discovery will help make meteorological models and climate change simulations more accurate.
The technique is used for in vitro studies of the behavior of astrocytes in a three-dimensional format, and can be adapted for neurons and other cell types. The model has been used to investigate the effects of COVID-19 on the central nervous system.
The clinical trial involved 44 volunteers with advanced bladder cancer. The award of a US patent should facilitate cooperation between the researchers and the pharmaceutical industry to proceed to the next stage of drug development.
Brazilian researchers demonstrate in field experiments that these large mammals help keep a balance between areas with different levels of productivity in biomes like the Atlantic Rainforest and regulate the spatial structure of plant communities.
Brazilian researchers followed 38 COVID-19 patients and found that it took a month on average for the diagnostic test to become negative. In three patients, the virus remained detectable for more than 70 days.
Scientists affiliated with institutions in Brazil and elsewhere presented research findings that highlighted the importance of data sharing in the fight against COVID-19.
