There's good news for chocolate and wine lovers, as scientists have found some of our favorite treats may help reduce the risk of heart disease. A study of more than 6,000 people found a link between diets rich in foods including fruit, vegetables, chocolate, coffee and wine, and the reduced risk of metabolic syndrome. Metabolic syndrome is a cluster of conditions that occur together—including increased blood pressure, high blood sugar, excess body fat around the waist and [...]

Getting your steps in could help fight off Alzheimer's, new research has found. Regular aerobic exercise was linked to a reduction in markers in the brains of in rats that associated with the onset of Alzheimer's, including amyloid plaques, according to a new paper in the journal Brain Research. Doing cardio could therefore help fight off the development of Alzheimer's, the researchers say. "Alzheimer's is a progressive neurodegenerative disorder with no known [...]

While humans may think of agriculture as a uniquely human achievement, ants have been farming their own food for millions of years, a new study has revealed. Researchers found that ants began cultivating fungi 66 million years ago, around the time an asteroid struck Earth and caused a global mass extinction. This mass extinction event, which wiped out the dinosaurs, also created conditions that allowed fungi to thrive. With plentiful decaying plant matter on the [...]

Ultra-processed foods, such as meat replacements and protein powders, allow vegans to meet their protein requirements, according to recent research. Nutrition experts have often debated whether a vegan diet can provide enough protein because plant-based foods tend to be less protein-rich than meat, eggs and dairy. However, the 774 vegan Brazilians who participated in this study were found, on average, to consume a healthy amount of protein and all the essential amino acids, which are the [...]

Cheese could be healthier in the future now that microbiologists in Brazil have discovered three novel strains of probiotic bacteria in samples of traditional cheeses. Probiotics are live microorganisms that, when eaten in food, may remain in the gut. People who have lots of—and lots of different types of—probiotic bacteria and yeasts in their gut are thought to have healthy microbiomes, i.e., microbial communities. A healthy gut microbiome is associated with good mental [...]

Researchers in Brazil have discovered that both Mayaro and chikungunya viruses are unexpectedly circulating in the Amazon rainforest at the same time. This discovery overturns the belief that antibodies from one virus would prevent an infection influx from the other in the same area. Samples analyzed between December 2018 and December 2021 showed outbreaks of both infections in Roraima, Brazil's northernmost state. Mayaro and chikungunya are arboviruses, viruses [...]

A huge amount of cocaine contamination in Brazilian waters could be making marine life high, with a range of severe effects. The drug has been found in the water and sediments of the Bay of Santos, one hour from the city of São Paulo, researchers at the Federal University of São Paulo (UNIFESP) have found. Santos, with its beach, is a popular destination for São Paulo residents and the area is home to the largest seaport in Latin America. Researchers found through a [...]

The Amazon may be approaching the point of near total collapse, a new study has concluded. The research, published in the journal Nature , found that climate change, combined with water stress and deforestation, could be pushing the Amazon rainforest closer to a tipping point where it is at risk of near or total collapse. Led by the Federal University of Santa Catarina in Brazil, alongside experts from the University of Birmingham in the U.K., scientists identified thresholds [...]

A new species of jellyfish has been discovered deep below the waves, and it may possess venoms that we have never seen before. The new species, named Santjordia pagesi , was discovered at a depth of 2,664 feet near Japan's Ogasawara Islands, floating around a deep-sea volcano known as the Sumisu Caldera. The new jellyfish, which has been sighted only twice, is an umbrella-shaped medusa species, measuring around 4 inches across and with a red cross in the center of its body, according [...]
