Recent research has found that screen time of more than three hours a day, proximity to the screen, and poor posture such as sitting or lying on your stomach are risk factors for thoracic spine pain (TSP) in 14- to 18-year-old students. The study, which showed a one-year TSP prevalence of 38.4% and an incidence of 10.1%, suggested that these results could inform health education programs and strategies to reduce TSP risk, and stressed the importance as adolescents with back pain are often less [...]

Brazilian scientists are proposing to conduct experiments on lab-grown mini-brains to study the effects of drugs on fetal brain development. Depression affects a significant proportion of pregnant women worldwide, with estimates ranging from 10% to 16%. While most women can improve with the help of antidepressants, the effects of these drugs on fetal brain development are not fully understood. Brazilian researchers reviewed over 100 scientific articles on the subject and concluded that [...]

Jairo Kenupp Bastos first heard about the insect while visiting Canavieiras on the southern coast of Bahia, a state in northeastern Brazil. “Local beekeepers told me about a tiny beetle that was digging holes in a plant called Dalbergia ecastaphyllum [Coinvine]a member of the pea family, and that the holes leaked a resin that was used by bees to make red propolis,” said Bastos, professor of pharmacognosy (the study of medicines made from natural sources such as plants, animals and [...]

Washington, January 31st - Some people infected with SARS-CoV-2 may be able to transmit the virus for longer than the recommended quarantine period without necessarily showing symptoms in the final stages of infection, a study has found. The study, recently published in the journal Frontiers in Medicine, included 38 Brazilian patients who were followed weekly between April and November 2020. Researchers at the Pasteur-USP Scientific Platform, a partnership between France’s [...]

Researchers at the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, in collaboration with colleagues from University College London in the UK, have discovered an efficient, simple and inexpensive way to predict the risk of functional impairment in the elderly. They analyzed data from more than 3,000 over-60s living in England and found that walking slowly alone can be viewed as a predictor of loss of the ability to perform the basic and instrumental [...]

Magnetizing a material without applying an external magnetic field is suggested by researchers at São Paulo State University (UNESP), Brazil, in an article published in the journal Scientific reportswhere they describe the experimental approach used to achieve this goal. The study was part of the Ph.D. Research by Lucas Squillante under the direction of Mariano de Souza, professor at the Department of Physics at UNESP in Rio Claro. Contributions were also made by Isys Mello, another [...]

Consuming low-calorie foods can have a protective effect against certain diseases, as the number of calories that a person eats directly has an influence Researchers say the performance of different cells. The study in mice showed that a low-calorie diet can protect the brain from neuronal cell death associated with diseases such as Alzheimer's, Parkinson's, epilepsy and cerebral vascular accidents (CVA). "We are studying how dietary changes affect metabolism and how likely it is [...]
