Invasive alien species, defined as animals and plants that breed and disperse in a landscape beyond their native range, have negative environmental, social, and economic impacts. One example among many is the forage grass genus Brachiaria, originally African and introduced to Brazil to form cattle pasture. It has become a major threat to the survival of native species and biodiversity at several spatial scales. Complete eradication of invasive species is often impracticable. Attempts to do so [...]

Lung ultrasound, considered a simple method for diagnosing lung disease, can also help predict the clinical progression of severe COVID-19 patients, according to a study conducted at the University of São Paulo’s Medical School (FM-USP) in São Paulo City, Brazil. The principal investigator for the study was Heraldo Possolo de Souza, a professor at FM-USP and an attending physician at its teaching and general hospital, Hospital das Clínicas (HC). The researchers [...]

The COVID-19 pandemic has affected people’s behavior everywhere. Fear, apprehensiveness, sadness, anxiety, and other troublesome feelings have become part of the daily lives of many families since the first cases of the disease were officially recorded early last year. These turbulent feelings are often expressed in dreams reflecting a heavier burden of mental suffering, fear of contamination, stress caused by social distancing, and lack of physical contact with others. In addition, [...]

Technology based on nanoparticles identifies IgG antibodies and costs only about a fifth of similar devices now on the market. It was developed by scientists at the University of São Paulo and Brazilian startup Biolinker. A test that detects antibodies to the novel coronavirus in 10 minutes and costs only a fifth of the market average has been developed by researchers at the University of São Paulo’s São Carlos Chemistry Institute (IQSC-USP) and Brazilian startup [...]

Incubated at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, and supported by São Paulo Research Foundation- FAPESP’s Innovative Research in Small Business Program (PIPE), BIOinFOOD is a startup that is developing a rapid COVID-19 diagnostic test based on a patent application filed by students at UNICAMP’s Genomics and Bioenergy Laboratory. The test is based on a biosensor consisting of a genetically modified brewer’s yeast (Saccharomyces [...]

In a review article published in Frontiers of Endocrinology, Brazilian researchers estimate a reduction of 35% in levels of physical activity and a rise of 28% in sedentary behavior in the initial months of confinement imposed by the pandemic Social distancing and working from home help prevent transmission of the novel coronavirus but can be conducive to unhealthy behavior such as bingeing on fast food or spending more time in a chair or on a couch staring at a screen, and generally moving [...]

Brazilian researchers have managed to decipher the structure of a protein found in parasites that cause neglected tropical diseases, paving the way to the development of novel medications. Thanks to the discovery it will be possible to seek more potent molecules capable of destroying the pathogens directly, with fewer adverse side-effects for patients. The study detailed the structural characteristics of the protein deoxyhypusine synthase (DHS), found in Brugia malayi, one of the [...]

A study performed at one of the Research Centers supported by FAPESP resulted in development of a novel rehabilitation device. The article was recognized as outstanding by the 20th International Conference on Computational Science and its Applications Virtual reality-based rehabilitation programs are becoming an important complement to conventional motor therapy for stroke patients and individuals with neurodegenerative diseases. Immersion in virtual environments stimulates several sensory [...]

There is growing evidence that adipose tissue plays a key role in the aggravation of COVID-19. One of the theories under investigation is that fat cells (adipocytes) act as a reservoir for SARS-CoV-2 and increase viral load in obese or overweight individuals. Scientists also suspect that during infection fat cells release into the bloodstream substances that boost the inflammatory reaction triggered by the virus in the organism. These hypotheses are being investigated by researchers at the [...]
