Stanford predicts the impact of climate on a severe disease
Publicado em 06 agosto 2024
Investigators from Stanford and Brazil are collaborating to predict the impact of climate and environmental changes on the spread of schistosomiasis, a parasitic disease in Brazil.
The disease is spread by freshwater snails and affects over 200 million people in tropical regions worldwide. Climate change, deforestation, urban sprawl, and changing rainfall patterns can shift the locations where the snails thrive, affecting the spread of the disease. Roseli Tuan, a senior researcher at the [...]

State University of Campinas study improves quantum networks
Publicado em 12 dezembro 2023The development of advanced quantum networks for supercomputing heavily relies on transmitting information coherently across the electromagnetic spectrum, ranging from microwave to infrared frequencies. This capability is essential for achieving efficient and reliable communication within these networks. Quantum networking involves transmitting and manipulating quantum states, which are highly delicate and easily disrupted. Therefore, ensuring coherent transmission of information is [...]ver notícia -
Brazilian reserachers show how to unlock the strength of specialty glass with niobium oxide
Publicado em 06 setembro 2023Applications of specialty glass range from astronomy to medicine, as well as data and power transmission. The study combined spectroscopy and molecular dynamics (MD) and Monte-Carlo (MC) simulations to show how the structure of the material is affected by the addition of niobium oxide. A study conducted at the Center for Research, Education, and Innovation in Vitreous Materials (CeRTEV) in São Carlos, São Paulo state, Brazil, shows for the first time that including niobium [...]ver notícia -
Brazil identifies flood-prone areas of cities
Publicado em 12 junho 2023The study combined models that predict urban expansion and land-use changes with hydrodynamic models, and the results were validated using actual data for São Caetano do Sul, a city in metropolitan São Paulo. Scientists affiliated with the National Space Research Institute (INPE) in Brazil have combined models that predict urban expansion and land-use changes with hydrodynamic models to create a methodology capable of supplying geographical information that identifies [...]ver notícia -

Brazilian researchers develop tool that encodes patient data as DNA sequences to integrate databases for epidemiological analysis
Publicado em 04 outubro 2022Brazilian researchers have created an innovative and agile computational tool to link and analyze different health databases with millions of patient records. Called Tucuxi-BLAST, the platform encodes identification records in a database, such as patient name, mother’s name, and place of birth, using letters that represent the nucleotides in a DNA sequence (A, T, C, or G). This “conversion” of individuals to DNA enables accurate record linkage across databases despite [...]ver notícia -
Researchers use AI to define priority areas for action to combat deforestation in the Amazon
Publicado em 24 agosto 2022Using a method based on satellite images and artificial intelligence, Brazilian researchers have shown that the priority area for actions to combat illegal deforestation could comprise 27.8% less territory than the 11 municipalities monitored by the federal government under the current strategy, known as the Amazon Plan 2021/2022. This monitoring ignores new deforestation frontiers outside the targeted areas. According to an article by the researchers, published in June in Conservation [...]ver notícia -
Brazilian researchers show superconductivity at higher temperature than usual
Publicado em 10 agosto 2022Certain materials at very low temperatures conduct electric current without resistance or losses. This property, known as superconductivity, was discovered in 1911 by Dutch physicist Heike Kamerlingh Onnes (1853-1926), who won the 1913 Nobel Prize in Physics for his research in the field. Even though more than a century has passed since its discovery, research on superconductivity is still intense, owing both to the amount of information it provides about fundamental aspects of [...]ver notícia -
Brazilian researchers combine aerial photography, AI to identify urban areas at risk for diseases transmitted by mosquitoes
Publicado emBrazilian researchers have developed a computer program that locates swimming pools and rooftop water tanks in aerial photographs with the aid of artificial intelligence to help identify areas vulnerable to infestation by Aedes aegypti, the mosquito that transmits dengue, zika, chikungunya, and yellow fever. The innovation, which can also be used as a public policy tool for dynamic socio-economic mapping of urban areas, resulted from research and development work by professionals [...]ver notícia -
Even the smallest pollution particles change the rainfall regime in the Amazon
Publicado em 04 fevereiro 2022Researchers have found that nanoparticles resulting from human activities such as the burning of fossil fuels rapidly grow in the atmosphere and influence cloud formation Even the finest particles of pollution influence the process of cloud formation and the rainfall regime. A study conducted in Manaus, the capital of Amazonas state in Brazil’s northern region, shows that oxidation leads small aerosols expelled by factories and car exhausts, for example, to grow very rapidly, reaching [...]ver notícia
