An international team of researchers has developed an innovative strategy for producing new vaccines. They created a genetically modified version of the Chikungunya virus that replicates only once, yet still trains the immune system to defend itself without causing disease. In tests conducted on mice, a single dose of the formulation containing the modified immature virus was sufficient to generate antibodies and protect the rodents against lethal infection. The study was published in May in [...]

According to a study conducted in Brazil by researchers at the Federal University of São Paulo (UNIFESP) with participants from the São Paulo Epidemiological Sleep Study (EPISONO 2018), people with hypothyroidism experience a higher frequency and severity of obstructive sleep apnea (OSA). The results also indicated that patients receiving hormone replacement therapy for thyroid dysfunction slept longer and spent more time in deep sleep. The researchers from UNIFESP’s Department of [...]

People with chronic shoulder pain naturally avoid movements involving that part of the body, fearing they will injure themselves again or experience more discomfort. However, if this behavior continues beyond the necessary healing period for a fracture, the pain can become chronic and the joint can become more impaired. Consequently, patients have a poorer prognosis for regaining shoulder function, muscle strength, and mobility. This cycle can delay recovery and worsen functional impairment, [...]

A moth caterpillar identified by the agribusiness sector as one of the most destructive pests of soybean, cotton, and corn crops may harbor fungi and bacteria in its gut that can degrade expanded polystyrene, also known as Styrofoam. In an article published in the journal BMC Microbiology , researchers from the Federal University of São Carlos (UFSCar) and São Paulo State University (UNESP) in Brazil presented the results of a study investigating the gut microbiota of Helicoverpa armigera and [...]

The critically endangered sand tiger shark ( Carcharias taurus ) appears to have found a refuge off the northern coast of the state of São Paulo, Brazil, for mating and reproduction. This was revealed in a study conducted by scientists and divers in the Alcatrazes Archipelago, a protected marine area located 35 kilometers off the coast of São Sebastião. The results were published in the Journal of Fish Biology by researchers from the Federal University of São Paulo (UNIFESP), São Paulo [...]

Brazil’s HIV/AIDS response program is considered a success story. As early as 1987, Brazil became the first developing country to guarantee free treatment. The country is also known for its social activism, which helped build the Unified Health System (SUS) and shape public policies based on scientific evidence and human rights. Important milestones in the fight against AIDS emerged through the alliance between civil society, public health professionals, and the government, such as [...]

Xanthan gum is found almost everywhere. This food additive has thickening, stabilizing, and gelling properties and is one of the most widely used by the food industry to adjust the consistency of ice cream, yogurt, cakes, sauces, and gluten-free pasta. It is also used to prepare beverages for people with dysphagia, or difficulty swallowing. However, a study conducted at the Federal University of São Paulo (UNIFESP) in Brazil raised an important red flag by demonstrating that chronic xanthan [...]

According to a study that analyzed the behavior of 1,500 São Paulo residents between 2014 and 2024, the implementation of new bike lanes, parks, and other public facilities in the Brazilian city has encouraged transportation-related physical activity and promoted public health benefits. The researchers found that the presence of bike lanes within 500 meters of residents’ homes was a key factor in keeping them active and encouraging cycling. “We’re observing a natural experiment in [...]

A 0.5% alcohol-based chlorhexidine antiseptic, combined with the natural organic compounds eugenol and menthol, can eliminate 99.9% of Candida parapsilosis cells. This fungus is one of the leading causes of infections in hospital settings, such as intensive care units (ICUs). During testing, the formulation was more effective at eliminating C. parapsilosis than 70% ethanol, a common alternative for this type of disinfection. The results were published in the journal Pathogens . The discovery [...]
