This 23-second balance test more accurately predicts one's fall risk
Publicado em 12 de fevereiro de 2025
Current 10-second balance tests may miss early warning signs of fall risk in older adults; researchers recommend extending tests to 23 seconds or longer for better prediction
For every extra second someone can maintain challenging positions like heel-to-toe or single-leg stance, their risk of falling in the next 6 months drops by 5%
Healthcare providers can use this simple timing test without special equipment, making it accessible for any clinical setting while potentially preventing [...]

76% fewer brain plaques: Aerobic exercise proves powerful weapon against Alzheimer's
Publicado em 20 janeiro 2025Brain cells regenerate, inflammation could drop as much as 68% when seniors exercise regularly BRISTOL, England — As pharmaceutical companies pour billions into developing new Alzheimer's treatments, researchers at the University of Bristol and Federal University of São Paulo have uncovered evidence that a far simpler intervention – regular aerobic exercise – might offer comprehensive protection against the disease. Their study reveals how physical activity [...]ver notícia -
An asteroid wiped out the dinosaurs — But it invented something amazing for ants
Publicado em 19 outubro 2024WASHINGTON — The asteroid that wiped out the dinosaurs also brought opportunities for new life. Scientists have found that after the asteroid wiped out many plants, ants started farming fungi to help them survive and get the food they needed in tough times. The meteor impact 66 million years ago created a low-light environment that allowed fungi that fed on organic matter to survive, as many plants and animals died. Additionally, the dust in the skies made it difficult for plants to [...]ver notícia -

Brazilian Frogs Unleash Ear-Piercing Ultrasonic Screams To Deter Predators, Study Finds
Publicado em 09 abril 2024SÃO PAULO, Brazil — In the lush depths of Brazil's Atlantic Rainforest, a tiny frog has been hiding a secret weapon: a scream so intensely high-pitched that it's inaudible to human ears. This groundbreaking discovery, reported in the journal Acta Ethologica , marks the first recorded use of ultrasound by amphibians in South America and sheds light on a never-before-seen defense mechanism against predators. The star of this study is the Leaf litter frog Haddadus [...]ver notícia -
An Overactive Brain Circuit May Explain Persistent Food Cravings
Publicado emLOS ANGELES — If you're guilty of opening up the fridge or pantry right after eating a meal, it might not just be because your appetite is too big. Psychologists from the University of California Los Angeles (UCLA) have discovered that people who do this might have overactive food-seeking neurons. During experiments with mice, researchers found a circuit in the brain that makes them crave food and go looking for it, even when they weren't hungry. When stimulated, this [...]ver notícia -
Glitter is even worse for the environment than anyone thought
Publicado emKey Findings: Glitter polluting oceans and rivers is blocking out sunlight underwater. Photosynthesis rates were significantly higher in cleaner bodies of water. The problem stems from metals like aluminum in glitter. SÃO PAULO, Brazil — It might be time to put down the glitter and find a new way to sparkle. Researchers at the Federal University of São Carlos (UFSCar) in Brazil found a hazard posed by glitter: its detrimental effect on aquatic life. Glitter , [...]ver notícia -
Mental illness may be waiting for stressed out teens in adulthood
Publicado em 31 janeiro 2024SÃO PAULO, Brazil — Teenagers who are constantly stressed out have a higher risk of suffering mental illness when they enter adulthood. Researchers at the University of São Paulo's Ribeirão Preto Medical School (FMRP-USP) in Brazil have discovered that excessive stress during adolescence can lead to changes in the gene expression in the brain. These changes, particularly in genes related to bioenergy, may impact cell respiration, leading to behavioral issues [...]ver notícia -
Common treatment for sleep apnea also slows the aging process
Publicado em 16 outubro 2023SÃO PAULO, Brazil — Obstructive sleep apnea (OSA), a condition where breathing stops repeatedly during sleep, not only disrupts one's peaceful slumber but also has links to a host of health issues including hypertension, heart failure, and even diabetes. Symptoms such as fatigue, daytime drowsiness, and memory lapses can severely hamper an individual's quality of life. However, a new ray of hope has emerged as Brazilian researchers have found that a common sleep apnea [...]ver notícia -
We're swimming in glitter: Over 8 million metric tons of tiny plastics found in oceans
Publicado em 10 outubro 2023SÃO PAULO, Brazil — Festive glitter, a common ingredient in makeup, greeting cards, and holiday decorations, may have a darker side than its shiny surface suggests. Researchers from the University of São Paulo (USP) in Brazil have found that glitter can negatively impact aquatic organisms vital to underwater ecosystems, with several million metric tons winding up in the oceans. Popular in various products, from nail polish to Carnival [...]ver notícia
