Researchers at the Faculty of Chemical Engineering (FEQ) of the State University of Campinas (Unicamp) have developed a carbon dioxide (CO₂)-based technology to dry sugarcane bagasse, a process that could significantly improve energy generation and operational efficiency at sugar and ethanol mills. The technology, licensed to Unicamp spin-off company Quimergia Inovação, uses carbon dioxide generated within sugar mills as the drying medium instead of conventional hot combustion gases, [...]

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 [...]

Recent research has revealed intriguing insights into the capabilities of some long-necked dinosaurs, particularly two South American sauropods: Uberabatitan from Brazil and Neuquensaurus from Argentina. Approximately 66 million years ago, these dinosaurs exhibited the ability to stand upright on their hind legs, a skill believed to be more practiced when they were younger and smaller in size. This capacity to elevate their front ends may have served multiple purposes, such as accessing high [...]

Life in the Atlantic Forest is rarely static. Even animals that spend much of their time high in the canopy must constantly balance feeding, avoiding rivals, conserving energy and coping with changing weather. For brown howler monkeys, that balancing act appears to shape how far they travel each day. A study published in the International Journal of Primatology, titled “ Determinants of daily path length in Alouatta guariba in a continuous forest ”, examined the daily movements of a wild [...]

People living with diabetes may face a much tougher road to recovery after COVID-19 than previously thought, with lingering health problems affecting their heart, mobility and daily life months after leaving hospital, according to a new study from the University of São Paulo published in Scientific Reports. The Brazilian researchers followed 870 adults who had been hospitalised with COVID-19 during the first wave of the pandemic, before vaccines became available. Around seven months after [...]

When we stroll along the sunny, picturesque beaches of Rio de Janeiro or sit by the tranquil banks of a wide Amazonian river, our minds usually drift toward a very specific scene of pristine tropical wilderness. We picture clean, undisturbed waters teeming with vibrant native fish, colourful birds nesting in thick overhanging branches, and a perfectly balanced aquatic ecosystem that has remained unchanged for thousands of years. For generations, traditional coastal and rural life has taught us [...]

Researchers in Brazil have developed an innovative biomaterial utilizing components such as jackfruit latex, pomegranate peel extract, and simvastatin, a medication commonly used to lower cholesterol. This new composite could represent a significant advancement in the treatment of periodontitis, a severe gum disease that affects the supporting structures of teeth and ultimately leads to complications like bone loss. The research team hails from the Faculty of Medical and Health Sciences [...]

For years, scientists have studied how animals protect and care for their young, but harvestman spiders have revealed a surprising twist. In many species, fathers—not mothers—take on the responsibility of guarding eggs. Researchers have used decades of field observations combined with citizen science data to uncover how this rare parenting behavior evolved. The discovery shows how online platforms like iNaturalist are changing the way scientists study the natural world. The world of [...]

How could 45 newly discovered Salmonella toxins help scientists develop future antibiotics and therapies? Scientists at the University of São Paulo (USP) in Brazil have identified 45 previously unknown toxins produced by Salmonella bacteria, including strains linked to foodborne illnesses. The discovery, made by researchers at the Center for Research in Bacterial and Bacteriophage Biology (B3 RIDC), provides new insights into how bacteria compete and survive in complex microbial [...]
