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 [...]

Scientists have developed a new electronic chip component that works more like the human brain than today’s computers. The new device can both process information and store it at the same time, which could help create faster, smarter and more energy-efficient computers in the future. The research was carried out by an international team of scientists, including Professor Victor López-Richard from the Federal University of São Carlos (UFSCar) in Brazil. Their findings were published [...]

The giant trees of tropical forests are important allies in the fight against climate change due to their ability to store carbon, yet they are still poorly understood by science. However, a study published July 2, 2026, in the journal Science reveals a crucial survival mechanism: these trees, which exceed 70 meters in height, have no difficulty transporting water to their tops and are no more vulnerable than smaller trees. They have developed internal adaptations that compensate for the [...]

A new study published in New Contaminants suggests that several drugs widely used during the COVID-19 pandemic can be toxic to marine organisms, even at relatively low concentrations. The research tested five pharmaceuticals, hydroxychloroquine, ivermectin, nitazoxanide, loratadine, and betamethasone, on nauplii of the brine shrimp Artemia salina, a small crustacean commonly used in marine ecotoxicology. "The pandemic changed not only public health systems, but also the chemical pressure [...]

A study published in the journal Biological Invasions indicates that Brazil currently has at least 82 non-native mollusk species, in addition to 13 whose origin cannot be determined. This represents a 215% increase compared to 2011, when 26 species were reported. Twenty of these species are considered invasive because they cause ecological, socioeconomic, or health damage. Thirteen species have insufficient data to determine their impact. This is the most comprehensive inventory of [...]

Major liver surgery places extraordinary demands on the body. Although the liver is famous for its ability to regenerate, rebuilding lost tissue requires huge amounts of energy, healthy cells, and careful coordination inside the organ. Scientists are increasingly exploring whether they can strengthen the liver before surgery instead of focusing only on recovery afterward. A new study from researchers at the State University of Campinas (UNICAMP) in Brazil suggests that a common [...]

People with diabetes who have had COVID-19 tend to recover more slowly, experience more long COVID complications, have a poorer quality of life, and require closer and more prolonged monitoring by medical teams. This was demonstrated in a study by the University of São Paulo, which involved 870 individuals followed for up to seven months after hospitalization. The study was published in the journal Scientific Reports. "Diabetes isn't only a risk factor for the acute phase of [...]
