Resonant-tunneling diodes are used in high-frequency oscillators, wave emitters and detectors, logic gates, photodetectors, and optoelectronic circuits. The study was a collaboration between Brazilian and German researchers.
The new cutoff values for a metric widely used by geriatricians, physical therapists and nutritionists are more accurate, facilitate early diagnosis and contribute to preventive treatment.
The researchers concluded that water stress, soil fertility and human-induced forest degradation cause gaps in the world’s largest tropical forest.
By means of specific biomarkers, a diagnostic test developed by the Brazilian startup Onkos shows whether a lump in the gland is benign or malignant, reducing the risk of unnecessary surgery.
The platform developed by researchers from Brazil and Chile lets users view geolocation of cases, deaths and vaccinations over time.
A study by the University of São Paulo has discovered that when macrophages engulf cells infected by the novel coronavirus, they begin producing excessive amounts of pro-inflammatory molecules, and their capacity to recognize and phagocytize dead cells is reduced twelvefold.
Brazilian researchers monitoring the population of metropolitan São Paulo have reported atypical cases in which SARS-CoV-2 continues to replicate in the organism for longer than the recommended isolation period.
A method created in Brazil by the Human Genome and Stem Cell Research Center could be used for large-scale production of livers for transplantation.
Brazilians are working in more than 60 scientific fields in over 50 German cities. An online event hosted by the Brazilian Embassy in Berlin featured researchers and representatives of institutions.
In an online seminar hosted by FAPESP, researchers from Brazil, the United States and France analyzed the impact of the pandemic on educational inequality.
Extracorporeal membrane oxygenation (ECMO) can keep patients alive until the disease recedes.
Brazilian researchers treated cells infected by SARS-CoV-2 with compounds produced by gut microbiota from dietary fiber. The intervention did not mitigate viral replication but reduced expression of a gene that plays a key role in viral entry into cells and a receptor involved in the inflammatory process.
Luciferin-luciferase system developed in collaboration with Japanese researchers produces brighter and longer-lasting far red light. The innovation can be used to image cells and tissues for diagnosis and biomedical research.
Laboratory trial by Butantan Institute in partnership with the University of São Paulo involved inoculation of variants P.1 and P.2 into cultured cells containing blood serum from vaccinated subjects. The results were satisfactory, according to the researchers.
The technology uses ultraviolet-C, which can inactivate the novel coronavirus. Startup BioLambda was supported by FAPESP and partnered with the Albert Einstein Jewish-Brazilian Hospital in São Paulo.
Brazilian researchers tested the capacity of different materials to produce sensors for the detection of PCA3, a gene that is overexpressed in prostate cancer. The technique can also be used to diagnose infectious diseases, including COVID-19.
In a study of the effects of cigarette smoking on exacerbation of the disease, scientists at a FAPESP-supported research center identified a novel pathway in the inflammatory process relating to bone damage.
In Araraquara, state of São Paulo, researchers detected the P.1 variant in 93% of samples from patients diagnosed at a primary healthcare facility in the first two months of the year.
Blood plasma from COVID-19 convalescents was tested against Brazilian variant isolates obtained from patients diagnosed in Manaus. The study also assessed the effectiveness of plasma from volunteers immunized with CoronaVac.
Published by an Anglo-Brazilian epidemiological research center, the study revealed that in only seven weeks SARS-CoV-2 lineage P.1 became the most prevalent strain of the virus in Manaus. Analysis of more than 900 samples from patients diagnosed in the period pointed to a higher viral load.
In a study conducted at the University of São Paulo, researchers used infrared laser irradiation to accelerate the activity of enzymes immobilized on gold nanoparticles. The technique could have biomedical and industrial applications.
Developed by researchers at the University of São Paulo, the non-invasive methodology facilitates identification of immature or poor-quality seeds without destroying them or creating residues.
Study conducted at University of Campinas in collaboration with University of Michigan explains nanoscale physics of this manmade material in article published in Science Advances.
Agricultural residues already produce 25% of the electricity used by households in the state. The proportion could jump to 70%, according to researchers who took part in an online seminar on the topic.
