Researchers have designed a probiotic to suppress autoimmunity in the brain, which occurs when the immune system attacks the cells of the central nervous system and  is at the core of several diseases, including multiple sclerosis. In a new study, researchers at Brigham and Women’s Hospital demonstrated the treatment’s potential using preclinical models of these diseases, finding that the technique offered a more precise way to target brain inflammation with reduced [...]

A type of soil called terra preta da Amazônia, or Amazon dark earth (ADE), promotes faster growth of trees and enhances their development in qualitative terms, according to an article published in the journal Frontiers in Soil Science. The findings reported in the article resulted from studies supported by FAPESP (projects 20/08927-0, 18/19000-4 and 14/50320-4) under the aegis of its Biodiversity, Characterization, Conservation, Restoration and [...]

Regular physical exercise, such as resistance training, can prevent Alzheimer’s disease, or at least delay the appearance of symptoms, and serves as a simple and affordable therapy for Alzheimer’s patients. This is the conclusion of an article published in Frontiers in Neuroscience by Brazilian researchers affiliated with the Federal University of São Paulo (UNIFESP) and the University of São Paulo (USP). Although older people and dementia [...]

Low-level laser therapy proves to be the most effective treatment for tinnitus, a widespread symptom affecting around 750 million people worldwide, as revealed by a study conducted by Brazilian scientists from the Optics and Photonics Research Center (CEPOF). The research indicates that laser therapy, including laser acupuncture, significantly helps alleviate tinnitus symptoms through anti-inflammatory action and promoting inner ear cell proliferation and blood flow. CEPOF, a Research, [...]

Bone cavities called air sacs appeared in the ancestors of long-necked dinosaurs about 225 million years ago, according to the analysis of a specimen found in Rio Grande do Sul state, South Brazil. The study also shows that air sacs did not evolve as linearly as scientists believe (credit: Márcio L. Castro) The missing link has just been found between the earliest dinosaurs, whose size ranged from a few centimeters to at most 3 meters in length, and more recent giants that could be [...]

A recent study conducted at the State University of Campinas (UNICAMP) in São Paulo, Brazil, has shed light on the question of which type of resistance training promotes greater muscle growth: high load with fewer repetitions or low load with more repetitions. Surprisingly, the study found that it makes no difference. The eight-week study involved 18 volunteers who were divided into two groups following different training protocols. One group performed high-load (HL) exercises with [...]

A study by researchers at the State University of Campinas showed that although the two types of training produce similar metabolic stress, muscle activation is different.   Peer-Reviewed Publication FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO Which kind of resistance training promotes more muscle growth: low load with many repetitions or high load with fewer repetitions? According to a study conducted at the State University of Campinas [...]

Researchers at the University of São Paulo (USP) in Brazil are using artificial intelligence (AI) and Twitter, one of the world’s largest social media platforms, to try to create anxiety and depression prediction models that could in future provide signs of these disorders before clinical diagnosis. The study is reported in an article published in the journal Language Resources and Evaluation. Construction of a database, called SetembroBR, was the first step in the study. The [...]

Pain afflicts at least 1.5 billion people worldwide, and despite the availability of various painkilling drugs, not all forms of pain are treatable. Moreover, pain medications can have side-effects such as dependence and tolerance, especially in the case of morphine and other opioids. In search of novel painkillers, researchers at Butantan Institute’s Special Pain and Signaling Laboratory (LEDS) in São Paulo, Brazil, studied TRPV1, a sensory neuron receptor that captures noxious [...]
