As cancer cases have increased worldwide, the disease has become more complex, presenting challenges to scientific advances in diagnosis and treatment. In this context, artificial intelligence (AI) has emerged as a valuable tool for predicting and detecting cases. A tool developed by Brazilian and Polish researchers may contribute to this process. The machine learning model can predict the aggressiveness of certain tumors by identifying specific proteins. It generates a stemness index [...]

The age at which a woman has her first period can offer valuable clues about her long-term risk for conditions like obesity, diabetes, heart disease and reproductive health issues, according to a study being presented Sunday at ENDO 2025, the Endocrine Society's annual meeting in San Francisco, Calif. The Brazilian study found that both early and late menarche-the age when women first get their period-are linked to different health risks. Women who had their first period before age 10 [...]

Researchers at the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, are developing a panel of biomarkers for the early detection of Alzheimer's disease and for distinguishing it from other types of dementia using blood tests. The research project is supported by FAPESP and is based on the genotype analysis of 500 volunteers with and without the disease. One of the most recent findings by the research group, published in the journal Neurobiology [...]

Long overlooked and underestimated, glial cells - non-neuronal cells that support, protect and communicate with neurons - are finally stepping into the neuroscience spotlight. A new Florida Atlantic University study highlights the surprising influence of a particular glial cell, revealing that it plays a much more active and dynamic role in brain function than previously thought. Using sophisticated computational modeling and machine learning, researchers discovered how [...]

The growing demand for healthy alternatives to traditional wheat products has boosted the search for new functional ingredients. In this context, partially defatted sunflower seed flour (SF) – a by-product of industrial sunflower oil extraction – is a promising option for enriching breads with proteins, fibers, and antioxidant compounds. "Our aim was to optimize the reuse of sunflower seed flour considering its high protein and chlorogenic acid content," says [...]

In recent years, scientists have been exploring the use of renewable polymers derived from natural sources. Materials such as vegetable cellulose, bacterial cellulose, chitosan, and starch offer attractive properties for biomedical applications, especially in controlled drug release systems and regenerative medicine. However, despite their potential, many of these polymers still face significant challenges in reaching commercialization. The study conducted by Lopes et al. points out that [...]

A study by the Center for Redox Processes in Biomedicine (Redoxoma) led by Marilene Demasi from the Butantan Institute (São Paulo, Brazil) presents a valuable new experimental model for investigating the interaction between the proteasome and mitochondrial function. In eukaryotic cells, the proteasome is a protein complex responsible for eliminating damaged and nonfunctional proteins, thereby helping to maintain cellular balance and proper functioning. In recent years, studies have [...]
