Researchers in Brazil have found that a simple vitamin D supplement may help chemotherapy work better in women with breast cancer. The study, carried out at the Botucatu School of Medicine at São Paulo State University (FMB-UNESP), suggests that low doses of the vitamin could improve treatment outcomes and potentially serve as a more accessible option compared to certain expensive or hard-to-obtain drugs designed to enhance chemotherapy response. The research, funded by FAPESP, included 80 [...]

Researchers at the Institute of Science and Technology of São Paulo State University (ICT-UNESP) in São José dos Campos, Brazil, have found that Moringa oleifera , commonly known as moringa or white acacia, could help remove microplastics from water. The findings were published in ACS Omega , a journal of the American Chemical Society. Moringa is native to India and grows well in many tropical regions. Its leaves and seeds are widely consumed as food due to their nutritional value. [...]

Researchers in Brazil are advancing a promising form of cancer immunotherapy by making natural killer (NK) cells more powerful and precise. In a recent study, scientists at the Ribeirão Preto Blood Center and the Center for Cell-Based Therapy (CTC) used the NK-92 cell line to test new designs of chimeric antigen receptors (CARs). These engineered receptors included specific costimulatory components, such as 2B4 and DAP12, that help activate the cells. The findings showed that these additions [...]

A new type of artificial saliva, delivered as a mouthwash and made using a lab-modified sugarcane protein called CANECPI-5, could help protect the teeth of patients with head and neck cancer. These patients often undergo radiotherapy near the mouth, which can damage salivary glands and reduce saliva production. Because saliva plays a key role in controlling bacteria and maintaining oral health, its loss can lead to serious dental problems. Researchers at the Bauru School of Dentistry at the [...]

Around 66 million years ago, two types of long-necked, four-legged dinosaurs stood out from other sauropods. They had the ability to rise up on their hind legs and stay upright for extended periods. This posture likely helped them reach leaves high in trees and may have made them look larger and more intimidating to predators. The Brazilian Uberabatitan and the Argentine Neuquensaurus were roughly the size of modern elephants. Even though they were considered small compared to other [...]

Researchers from the Federal University of São Carlos (UFSCar) in Brazil, working with University College London (UCL) in the United Kingdom, found that having both excess abdominal fat and reduced muscle mass significantly raises the risk of death. People with this combination were 83% more likely to die than those without either condition. This pairing points to a more serious underlying issue known as sarcopenic obesity. It occurs when muscle mass declines while body fat increases. The [...]

Researchers from the Center for Nuclear Energy in Agriculture at the University of São Paulo (CENA-USP) have identified multiple classes of antibiotics in the Piracicaba River, a major waterway in São Paulo state, Brazil. Their findings, published in Environmental Sciences Europe , show that these substances are not only present in the water but also accumulate in fish. The team also examined whether a common aquatic plant in the region, Salvinia auriculata , could help reduce this [...]

Researchers at the State University of Campinas (UNICAMP) in São Paulo, Brazil, have created a new product that blends native bee honey with cocoa bean shells. The result can be eaten on its own or added to foods and cosmetic formulations. The findings were published in ACS Sustainable Chemistry & Engineering, which highlighted the study on its cover. To make the product, the team used honey from native bees as a natural, edible solvent to draw out beneficial compounds from cocoa shells, a [...]

Scientists have identified Brazil's first known field of tektites, the glassy material created when an asteroid or other extraterrestrial object strikes Earth with extreme force. These newly recognized specimens, called geraisites after the state of Minas Gerais where they were first found, form a previously unknown strewn field. The discovery helps fill gaps in South America's incomplete record of ancient impact events. The findings were detailed in the journal Geology by a research [...]
