"Our team has discovered a new fossil ant species representing the earliest undisputable geological record of ants," study co-author Anderson Lepeco, a researcher at the Zoological Museum of the University of São Paulo in Brazil, said in a statement. "What makes this discovery particularly interesting is that it belongs to the extinct 'hell ant,' known for their bizarre predatory adaptations." The newly discovered ancient ant species, which researchers have [...]

Adverse situations experienced by the mother during childhood – such as neglect or physical, psychological or sexual violence – can trigger excessive weight gain in male children as early as the first two months of life. This was shown in a study that followed 352 pairs of newborns and their mothers in the cities of Guarulhos and São Paulo, Brazil. The results were published in the journal Scientific Reports. The analyses indicated the occurrence of very early [...]

Scientists in Brazil have discovered that a specific protein in the brain, called hnRNP A1, plays a key role in protecting nerve fibers and could be important in treating diseases like schizophrenia and multiple sclerosis (MS). Their research, published in the Journal of Neurochemistry, focused on how this protein helps maintain the brain’s protective coating called myelin. Myelin is like an insulating layer around nerves. It helps messages travel quickly and smoothly between brain [...]

Research published in the Journal of Neurochemistry has detailed the role of a protein, hnRNP A1, in the formation and stability of myelin, suggesting an important impact on neurodegenerative diseases and mental disorders such as multiple sclerosis and schizophrenia. The findings pave the way for new research and potential treatments. Myelin is a fatty substance produced by oligodendrocytes (cells of the central nervous system) that forms a sheath, like a kind of "insulator." It [...]

Melanoma is the most aggressive form of skin cancer. Although less common, it is the most serious due to its high potential for metastasis. Despite the health benefits of sunlight, prolonged exposure to ultraviolet rays is the main risk factor for developing the disease. Excessive radiation induces oxidative stress and inflammation in skin cells through photo-oxidation reactions. Both ultraviolet and visible light can activate photosensitizers naturally present in tissues. This process [...]

Brazil is the world's largest producer of soybeans and one of the reasons is the incorporation of bio-inputs, microorganisms that promote biological nitrogen fixation. Without this practice, this essential nutrient would have to be supplemented with fertilizer. By managing fertilizer use, Brazilian growers can save an estimated USD 15 billion per year. The main bio-input used commercially today is bacteria of the genus Bradyrhizobium spp. (rhizobia). In a study supported by FAPESP , [...]

Drinking eight or more alcoholic beverages each week could have a damaging effect on the brain, according to a new study published in Neurology, the medical journal of the American Academy of Neurology (AAN). That volume of alcohol was linked to a higher risk of developing a type of brain lesion called hyaline arteriolosclerosis, which causes a narrowing and thickening of blood vessels and impedes the flow of blood in the brain. This can lead to memory and cognition problems, according to [...]
