Belly fat and weak muscles after 50 increase death risk by 83%
Publicado em 13 de dezembro de 2025
Many people know that too much belly fat can be bad for their health. But a new study shows that when belly fat is combined with muscle loss, the risk of dying goes up by 83%.
This is compared to people who don’t have these problems. The study was done by scientists from the Federal University of São Carlos in Brazil and University College London in the UK.
This dangerous combination is called sarcopenic obesity. It happens when a person loses muscle and gains fat at the same time. [...]

Brazilian plant could reduce inflammation and arthritis, study finds
Publicado em 12 dezembro 2025Researchers in Brazil have discovered that a native plant known as Joseph’s Coat (Alternanthera littoralis) may be useful in treating inflammation, pain, and arthritis. The study, published in the Journal of Ethnopharmacology, was conducted by scientists from the Federal University of Grande Dourados (UFGD), the State University of Campinas (UNICAMP), and São Paulo State University (UNESP). Joseph’s Coat grows along the Brazilian coast and has long been used in traditional medicine [...]ver notícia -
New drug could help reverse Alzheimer’s symptoms
Publicado em 23 novembro 2025A research team in Brazil has developed a new chemical compound that might one day help treat Alzheimer’s disease. The scientists, based at the Federal University of ABC (UFABC), used computer models, lab tests, and animal experiments to study the new drug. Their early results are promising, and they hope to work with pharmaceutical companies to begin testing the compound in human patients. The team’s main goal is to fight the buildup of beta-amyloid plaques in the brain. [...]ver notícia -
Ancient stone tools from Kenya reveal a turning point in human evolution
Publicado em 06 novembro 2025In a groundbreaking discovery, scientists have uncovered one of the oldest and longest-lasting collections of stone tools ever found—evidence that early humans had already mastered technology nearly 2.75 million years ago. The tools, discovered at the Namorotukunan Site in Kenya’s Turkana Basin, show that our ancient ancestors were remarkably skilled and adaptable, even as they faced dramatic environmental upheavals. The study, published in Nature Communications, describes how [...]ver notícia -
Mindfulness meditation could ease chronic jaw pain in women
Publicado em 05 novembro 2025Living with constant pain can wear down both body and mind. For women suffering from temporomandibular disorder (TMD)—a condition that affects the jaw joint and chewing muscles—everyday life can be a challenge. The disorder often causes persistent pain in the jaw, temples, face, or ears, along with headaches and difficulty chewing. Now, new research from the University of São Paulo (USP) in Brazil shows that practicing mindfulness meditation can help women with TMD [...]ver notícia -
How exercise trains the immune system to fight better
Publicado em 09 outubro 2025Exercise is well known for strengthening muscles, lungs, and the heart, but new research shows it also “trains” the immune system. An international team of scientists has found that older adults who have been doing endurance sports for decades have immune cells that are stronger, more adaptable, and less likely to trigger harmful inflammation. The study, published in Scientific Reports, looked closely at natural killer (NK) cells. These white blood cells are part of the [...]ver notícia -
‘Invisible’ asteroids near Venus could pose a future threat to Earth
Publicado em 24 setembro 2025Scientists have identified a hidden population of asteroids that could pose a serious threat to Earth, even though we can’t see them with current telescopes. These objects, known as Venusian co-orbital asteroids, share their orbit with Venus and remain extremely difficult to detect because of their position in the sky. A new study led by researchers at São Paulo State University (UNESP) in Brazil warns that some of these asteroids could one day cross Earth’s path and, [...]ver notícia -
Microplastics may be weakening our bones, scientists warn
Publicado em 21 setembro 2025Plastic has become a part of nearly every aspect of modern life. More than 400 million tons are produced each year, and the waste is polluting beaches, rivers, and even the deepest parts of the ocean—some as far down as 11,000 meters. Plastic is also a major contributor to climate change, releasing about 1.8 billion tons of greenhouse gases annually during production. But beyond its impact on the environment, scientists are now finding troubling evidence that plastics may also be [...]ver notícia -
Microplastics in daily products may damage your bones
Publicado em 20 setembro 2025Every year, over 400 million tons of plastic are produced and used around the world. This huge amount of plastic pollutes beaches, rivers, and even the deepest parts of the ocean—up to 11,000 meters down. But plastic doesn’t just hurt the environment. It also contributes to climate change, producing 1.8 billion tons of greenhouse gases each year. Scientists are also finding that plastic use can affect human health. Tiny plastic particles, known as microplastics, break off [...]ver notícia -
Blood sugar swings may signal more severe heart attack damage
Publicado em 06 setembro 2025A new study by Brazilian researchers has found that variations in blood sugar levels may help predict how much damage a heart attack causes, regardless of whether the patient has diabetes. The findings, published in Diabetology & Metabolic Syndrome, suggest that a simple, inexpensive test could become an important tool for identifying patients at higher risk after their first heart attack. The research focused on “glycemic delta,” which measures the difference between a [...]ver notícia
