Exercise and omega-3s could be the secret to healthier teeth
Publicado em 26 de outubro de 2025
Researchers found that combining regular exercise with omega-3 supplements can make a big difference for oral health. The duo helps the immune system fight off chronic tooth root infections and reduces bone loss around the teeth. In animal studies, those that both exercised and took omega-3s had much lower inflammation and healthier bone structure.
Working out and taking omega-3s may quietly heal your mouth from within. The combination helps the immune system reduce inflammation and protect [...]

Exercise might be the key to a younger, sharper immune system
Publicado em 15 outubro 2025Endurance exercise may train the immune system as much as the muscles. Older adults with decades of running or cycling had immune cells that functioned better and aged more slowly. Their inflammation levels were lower and their cells resisted fatigue even under stress. The findings point to a direct link between lifelong fitness and healthier immune regulation. Lifelong endurance training strengthens the immune system by making key defense cells more adaptable, efficient, and less [...]ver notícia -
Scientists reveal green tea's fat-burning secret
Publicado em 08 outubro 2025New research shows green tea may help the body burn fat and balance blood sugar. In a study with obese mice, it improved metabolism and muscle health without harming lean animals. Scientists say its powerful plant compounds work together to regulate fat and energy use. The findings hint that green tea could be a natural support for healthy weight management. Green tea extract helped obese mice lose up to 30% of their body weight and improved metabolic function, even under carefully [...]ver notícia -
A plant compound might be the secret weapon against gum disease
Publicado em 30 setembro 2025Morin-based powder, extracted from guava leaves, apple peel, and figs, can be slowly released with the help of polymers and serve as an alternative to antibiotics. A powder based on morin, a natural compound extracted from plants such as guava leaves, apple and fig peels, certain teas, and almonds, has shown antimicrobial, anti-inflammatory, and antioxidant effects against bacteria that cause periodontal disease. It is expected that the substance, released in a controlled manner through [...]ver notícia -
Scientists discover microplastics deep inside human bones
Publicado em 19 setembro 2025Plastic waste isn’t just choking oceans—it’s infiltrating our bodies in ways that scientists are only beginning to uncover. The production and use of over 400 million tons of plastic each year has polluted beaches, rivers, and even the deepest parts of the ocean, reaching depths of up to 11,000 meters. In addition to visible environmental impacts, plastic contributes to climate change. It is estimated that plastic production generates 1.8 billion tons of greenhouse gases [...]ver notícia -

Mysterious bone disease ravaged Brazil's giant dinosaurs
Publicado em 02 setembro 2025Researchers found sauropod bones with signs of osteomyelitis, an infectious disease that can be caused by viruses, bacteria, fungi, or protozoa and that killed the animals quickly. The discovery suggests that favorable conditions for the disease existed. Date: September 2, 2025 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Fossilized bones in Brazil reveal that deadly infections plagued sauropods 80 million years ago.

400-million-year-old fish exposes big mistake in how we understood evolution
Publicado em 29 julho 2025Researchers reanalyzed the skull musculature of coelacanths, a group of fish that has existed for 400 million years, and concluded that many structures had been incorrectly described.ver notícia -
Stirling Research Could Extend Biopesticide Effectiveness
Publicado em 27 maio 2025Changes to a pest's diet could slow the evolution of resistance to biopesticides, according to research from University of Stirling scientists. It is hoped that the findings could allow the development of biopesticides that are effective for longer, potentially increasing food security, reducing damage to the natural environment and boosting agro-ecological biodiversity. Researchers discovered that cotton bollworm pests -- a species of moth that can cause considerable agricultural [...]ver notícia -
Scientists have figured out how extinct giant ground sloths got so big and where it all went wrong
Publicado em 22 maio 2025Most of us are familiar with sloths, the bear-like animals that hang from trees, live life in the slow lane, take a month to digest a meal and poop just once a week. Their closest living relatives are anteaters and armadillos, and if that seems like an odd pairing, there’s a reason why. Today, there are only two sloth species, but historically, there were dozens of them, including one with a bottle-nosed snout that ate ants and another that likely resembled the ancestors of modern [...]ver notícia
