The study is published in PLOS ONE. Equations suggest viral population variability can be estimated on the basis of epidemiological data.

In a review of the scientific literature, researchers at the Federal University of São Paulo concluded that infection by SARS-CoV-2 during pregnancy can reduce the availability of ACE2, a protein that plays an important part in placental development, control of blood pressure, and the circulatory adaptations required for fetal development.

The result was obtained in a study of 20 volunteers by researchers at São Paulo State University. The treatment is painless and uses a weak current delivered by electrodes placed over specific brain regions.

Long-Term Monitoring of the Bat Species Saccopteryx bilineata in Their Natural Setting Revealed That Pups Display Babbling Behavior Strikingly Similar to That of Human Infants

A study conducted by researchers at the Center for Cell-Based Therapy in São Paulo State, Brazil, identified a genetic signature that can be used to predict whether patients should be submitted to radiation therapy

The results of a study conducted at a Brazilian university point the way to the development of more effective treatment for the cutaneous form of the disease.

Based on data collected in the field, Brazilian researchers showed that small and medium trees suffer most in the first two years after a fire, but the overall impact on vegetation can last decades. Carbon stocks fall 12.8% in burned areas on average.

In an article published in PNAS, researchers affiliated with Butantan Institute describe the genome of Bothrops jararaca and suggest the origin of genes responsible for toxins in its venom.

New Zealand Giraffe Weevils are not only the longest beetles in the world, they also have the biggest adult size-range discovered for any beetle species in the world. Researchers from the Smithsonian Tropical Research Institute, the University of Aukland and the University of Arizona found that larger weevils afford the energetic cost of maintaining disproportionately larger weapons because they make them out of a larger proportion of cuticle, a metabolically cheaper material.

Estudo divulgado na Nature Medicine avaliou indivíduos imunizados com a CoronaVac. Com base nos resultados, pesquisadores da Faculdade de Medicina da USP estão testando novas estratégias, entre elas suspender o tratamento desses pacientes uma ou duas semanas antes da vacinação.
