The results of a study conducted by Brazilian researchers will be useful both for epidemiological surveillance and to improve the treatment available to patients. An article on the study is published in PLOS ONE.
Genetic analysis of Aquarana catesbeiana, a species that originally came from North America and is now found in nine Brazilian states, shows that the lineage introduced in 1935 prevails in both captive and feral bullfrogs. Law enforcement to maintain sanitary standards is difficult. The invaders prey on native amphibians and transmit diseases to them.
The type of ependymoma studied mainly affects children, has a low survival rate and has no specific chemotherapeutic treatment. A combination of two experimental drugs inhibited tumor growth in vitro.
The combination is particularly dangerous for women, according to a study by researchers in Brazil and the UK who analyzed data for 5,310 people aged 50+ followed in a ten-year health survey.
Researchers in Brazil have developed a selection method performed directly with coffee beans in real time. It does not require roasting, does not destroy the samples and can be included as a step in the production process.
The topic was discussed on August 9 by Barry O’Keefe of the US National Cancer Institute during the FAPESP 60 Years School on Exact, Natural and Life Sciences. The other speakers on the second day of the event were José Nelson Onuchic of Rice University and Virgilio Almeida of the Federal University of Minas Gerais.
The system is being developed by a Brazilian startup supported by FAPESP and can be used by biologists in scientific research, by NGOs to track endangered species, and by environmental consultants.
This and related issues were discussed by Martin Ravallion from Georgetown University and Marcelo Medeiros from Columbia University (USA) during the 13th FAPESP 60 Years Conference.
While some patients die with a high viral load and little inflammation, others succumb to inflammatory complications that arise after the virus is eliminated from the organism. According to scientists at the University of São Paulo, lasting inflammasome activation is key in such cases. The findings can be used to develop personalized therapeutic approaches.
A study using satellite imagery and machine learning techniques shows that many deforestation hotspots lie outside the 11 municipalities currently monitored by the Brazilian federal government under its Amazon Plan 2021/2022.
Research conducted by Brazilian scientists has demonstrated that chlorophyll fluorescence is a reliable predictor of seed maturity. The greener the seed, the lower the quality. Manual separation is the rule in Brazil.
Researchers at the University of São Paulo in Brazil fed data for different coronaviruses into a machine learning model. The results reinforced the role of flying mammals as the first reservoirs of the virus that caused the COVID-19 pandemic. The tool can be used in future emergencies.
Astronomers from Brazil, Italy and South Africa have begun installing the first of nine telescopes sensitive to gamma rays on Tenerife in Spain’s Canary Islands.
The need to adapt was emphasized by Guy Brasseur, director of the Max Planck Institute for Meteorology, Nobel Peace Laureate in 2007, and keynote speaker on the last day of the FAPESP 60 Years School.
Researchers at the University of São Paulo in Brazil followed up hundreds of COVID patients after discharge from hospital in São Paulo City. Tests conducted six months later showed that those with the most severe sensory disorders also performed worse in tests of cognitive functions, especially memorization.
Spherules were discovered in the sediments present at depths of 180-224 m inside the crater located in São Paulo, Brazil. Their shape suggests local rock was pulverized, nebulized, and expelled upward by the collision.
Conducted by Brazilian researchers, the study focused on the fused deposition modeling technique and was featured on the cover of Analytical Chemistry, a journal of the American Chemical Society.
Funding from six institutions, including the São Paulo Research Foundation (FAPESP), will be used to accelerate completion of the GMT’s seven primary mirrors and scientific instrumentation.
In a webinar held to present the third chapter of the book published by the São Paulo State Academy of Sciences to commemorate FAPESP’s sixtieth anniversary, specialists showed that protection of terrestrial and marine environments contributes to food production and job creation, among other benefits.
Researchers at the University of São Paulo showed, through experiments on animals and genetically modified cells, that this type of cancer advances more slowly when the light-sensitive molecule known as melanopsin is deactivated. The discovery could point to novel therapeutic strategies.
Discovery by Brazilian researchers featured on cover of the journal Nanoscale is noteworthy because of possible applications in next-generation electronic devices.
Researchers at the University of São Paulo measured the speed with which volunteers recognized expressions of happiness, sadness, anger, disgust or fear. The participants were unknowingly exposed to different smells during the test. The findings are reported in PLOS ONE.
Researchers at the University of São Paulo tested a therapeutic intervention that proved capable of reducing the mortality rate from MA-ARDS in experiments on mice. The findings point to an avenue for the development of novel treatments for human patients.
In a longitudinal survey of children born in 2015 and 2016 in a city in Acre State, North Brazil, over half of the participants reported experiencing hunger in the previous month. The occurrence of symptoms also correlated with social vulnerability, and with the mother’s schooling and skin color.
The strategy was tested at the Federal University of São Carlos. The conversion took place under ambient temperature and pressure conditions, which could enable methane, a potent greenhouse gas, to be used to produce fuel. The process currently used by the chemical industry consumes large amounts of energy.
